    Full Text Available OBJECTIVE: To assess the occurrence of upper urinary tract urothelial tumors (UUTT in Brazil. MATERIALS AND METHODS: We performed a clinical and histopathologic study of 33 patients who were diagnosed with a malignant neoplasm in the renal pelvis or ureter in the period of 1994 to 2004, in a single institution. RESULTS: Among the patients with upper urinary tract carcinoma, 70% were males and 30% females, with mean age of 65 ± 16 years (ranging from 31 to 91 years. Nineteen patients presented renal pelvis tumor (58%, 9 ureteral tumor (27% and 5 synchronic pelvic and ureteral tumors (15%. Renal pelvis tumors represented 2.8% of all the urothelial neoplasms, and 11.4% of all renal neoplasms treated in the same period. Ureteral tumors represented 1.6% of all the urothelial malignancies surgically managed in these 11 years. Tobacco smoking was the most common risk factor, and analgesic abuse was not reported by those patients. Most carcinomas were high-grade and muscle-invasive. Mean time to diagnosis was 7 months, being hematuria the most common symptom. CONCLUSIONS: A high association was also found between UUTT and bladder urothelial carcinoma. UUTT were mostly seen in men in their seventies and related to a high overall and cancer-related mortality rate. The overall disease-specific survival was 40%, much lower than found in most of the reported series.

    Full Text Available Multilocular cystic nephroma (MCN is a rare tumor at the most benign end of the spectrum of the multilocular cystic neplasms of kidney. Nephrectomy is curative for MCN. In this case-report, we present a 16-month-old girl with a 10x15 cm multilocular cystic renal tumor extending into the renal pelvis and proximal ureter on the right side demonstrated on magnetic resonance imaging. Nephrectomy was performed. The pathology was completely consistent with MCN.

    1. We have investigated the effect of the potassium (K) channel opener, cromakalim, on the spontaneous myogenic activity of the guinea-pig isolated renal pelvis and on myogenic contractions evoked by direct electrical stimulation of the guinea-pig isolated ureter. 2. In the presence of Bay K 8644 (1 microM), electrical stimulation of the guinea-pig ureter (10 Hz for 1 s, pulse width 5 ms, 60 V) produced regular tetrodotoxin-(1 microM) resistant phasic contractions which were suppressed by 3 microM cromakalim. Glibenclamide (0.1-3 microM), 4-aminopyridine (4-AP, 0.1-2 mM) and tetraethylammonium (TEA, 1-10 mM) produced a concentration-dependent inhibition of the effect of cromakalim with the rank order of potency (EC50 in parentheses): glibenclamide (0.64 microM) > 4-AP (1.11 mM) > TEA (6.6 mM). Apamin (0.1-0.3 microM) was without effect. 3. Cromakalim (0.1-10 microM) produced concentration-dependent inhibition and suppression of spontaneous contractions of the guinea-pig isolated renal pelvis and of evoked contractions of the ureter with EC50 values of 0.71 and 0.47 microM, respectively. 4. Glibenclamide (1 microM) produced a rightward shift of the concentration-response curve to cromakalim in both the renal pelvis and ureter, without producing depression of the maximal inhibitory effect. Glibenclamide did not affect the spontaneous activity of the renal pelvis while it produced a slight enhancement (10-15% increase) of evoked contractions of the ureter. Glibenclamide did not affect the inhibitory action of the adenylate cyclase activator, forskolin, in the renal pelvis or ureter. 5. In electrophysiological experiments (sucrose gap), cromakalim (0.3 and 1 microM) produced hyperpolarization of ureter smooth muscle. Cromakalim also produced a transient suppression of action potentials and accompanying phasic contractions evoked by electrical stimulation. Before suppression of evoked contractions, a shortening of action potential duration was observed concomitant with

    The mechanism by which the ureteropelvic junction (UPJ) regulates the passage of urine from the renal pelvis to the ureter, and prevents urinary backflow from the the ureter to the renal pelvis, is not completely understood. The current communication studies this mechanism in 18 dogs. With the dogs under anesthesia, nephrostomy was done through which two catheters (one pressure and one balloon-tipped) were introduced into the UPJ and the renal pelvis, respectively. Renal pelvis distension with a balloon filled with 1 ml of saline effected a rise of renal pelvic pressure from a mean basal pressure of 4.8 +/- 1.2 cm H2O to 6.9 +/- 2.3 cm H2O (P pelvic balloon (P > 0.05). Renal pelvic distension with 2, 3, and 4 ml caused a significant rise of renal pelvic pressure to 8.4 +/- 2.7 (P 0.05). In contrast, the UPJ showed no significant pressure change upon distension of the locally anesthetized renal pelvis or ureter, respectively. Likewise, the locally anesthetized UPJ exhibited no significant pressure response to renal pelvic or ureteric distension. The study demonstrates that urine might have to accumulate in the renal pelvis up to a certain volume and pressure so as to effect UPJ opening, which occurs at its maximum irrespective of the distending volume. UPJ opening upon renal pelvic distension postulates a reflex relationship which we call "pelviureteral inhibitory reflex." This reflex is believed to regulate the passage of urine from the renal pelvis to the ureter. Ureteric distension closes the UPJ; we call this reflex action the "ureteropelvic excitatory reflex" as it seems to prevent reflux of urine through the UPJ and thus protects the kidney. The concept that the UPJ acts as a physiologic sphincter is put forward.

    BACKGROUND The American Joint Committee on Cancer’s (AJCC) 7th edition cancer staging manual reflects recent changes in cancer care practices. This report assesses changes from the AJCC 6th to the AJCC 7th edition stage distributions and the quality of site-specific factors (SSFs). METHODS Incidence data for renal parenchyma and pelvis and ureter cancers from 18 Surveillance, Epidemiology, and End Results (SEER) registries were examined, including staging trends during 2004–2010, stage distribution changes between the AJCC 6th and 7th editions, and SSF completeness for cases diagnosed in 2010. RESULTS From 2004 to 2010, the percentage of stage I renal parenchyma cancers increased from 50% to 58%, whereas stage IV and unknown stage cases decreased (18% to 15%, and 10% to 6%, respectively). During this period, the percentage of stage 0a renal pelvis and ureter cancers increased from 21% to 25%, and stage IV and unknown stage tumors decreased (20% to 18%, and 7% to 5%, respectively). Stage distributions under the AJCC 6th and 7th editions were about the same. For renal parenchymal cancers, 71%–90% of cases had known values for 6 required SSFs. For renal pelvis and ureter cancers, 74% of cases were coded as known for SSF1 (WHO/ISUP grade) and 47% as known for SSF2 (depth of renal parenchymal invasion). SSF values were known for larger proportions of cases with reported resections. CONCLUSIONS Stage distributions between the AJCC 6th and 7th editions were similar. SSFs were known for more than two-thirds of cases, providing more detail in the SEER database relevant to prognosis. PMID:25412394

    Our purpose was to delineate the course of the ureter in the female pelvis in relationship to several important surgical landmarks. Ten female cadavers with undissected pelves were used. The ureter was identified at the pelvic brim and traced inferiorly to the bladder. Sets of measurements (+/- 0.1 cm) that help define the location of the ureter were obtained at the three landmarks; the ischial spine, the obturator canal and the insertion of the arcus tendineus on the pubic bone. The mean distances from the ureter to the pelvic floor were ischial spine, 3.2 +/- 0.1 cm; obturator canal, 3.2 +/- 0.1 cm; and the insertion of the arcus tendineus on the pubic bone, 1.6 +/- 0.1 cm. The mean distances from the arcus tendineus to the pelvic floor were ischial spine, 1.9 +/- 0.1 cm; obturator canal, 2.8 +/- 0.1 cm; and the insertion of the arcus tendineus on the pubic bone, 3.2 +/- 0.1 cm. This study defines the relationship of the ureter to the pelvic floor through measurements taken at three landmarks. The data should be useful to pelvic surgeons and are important for the development of future surgical techniques.

    Most renal calculi can be classified using well-established criteria in a manner that reflects both composition and fine structure under specific pathophysiological conditions. However, when a large patient population is considered, rare renal calculi invariably appear, some of which have never been classified; careful study is required to establish stone etiology in such cases. The patient in the present case report formed two types of calculi. One was attached on the wall of the renal pelvis near the ureter and part of the calculus was embedded inside pelvic renal tissue. The calculus developed on an ossified calcification located in the pelvis tissue. Current knowledge on the development of calcification in soft tissues suggests a pre-existing injury as an inducer of its development. A mechanism of calculus formation is proposed. The second stone was a typical jack-stone calculus.

    Introduction Both, the renal pelvis and the ureter, are affected by developmental, reactive and neoplastic disorders, though rare in incidence. Aim This series of cases were analysed to study the clinicopathological characteristics of the common and comparatively rare lesions involving the renal pelvis and pelviureteric junction. Materials and Methods A retrospective collection of 476 nephrectomies and pelviureteric junction resections, received over a period of 13 years from 2001 to 2013 was done. The patients’ clinical details were obtained and the histopathological findings reviewed. The lesions were classified into non-neoplastic and neoplastic categories. Results Primary involvement of the renal pelvis and pelviureteric junction was seen in 105 of 476 specimens. The mean age was 54.5 years with a male to female ratio of 2.2:1. The non-neoplastic lesions accounted for 76.2% of cases with a majority being pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy (68.6%) causing hydronephrosis. Urothelial carcinomas were encountered in 20% of the cases. A majority of the urothelial carcinomas were infiltrative (81%) and high grade (71%) tumours. Conclusion Renal pelvis, a conduit to propel urine, can be the site for numerous disorders. Non-neoplastic lesions were more common than neoplasms. Pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy was the commonest lesion in our study. In the neoplastic category, urothelial carcinoma was most common. However, rare lesions such as hamartomatous fibroepithelial polyp, Von Brunn’s nests, flat urothelial hyperplasia and intramuscular haemangioma of upper ureter at the pelviureteric junction were encountered along with occasional cases of tuberculosis and squamous cell carcinomas.

    Full Text Available Urothelial carcinomas are the most common neoplasms in the renal pelvis. However mucinous cystadenocarcinomas (MCA are very rare in this localization. Although some theories are attributed on the patogenesis of MCA, its exact etiology is not known. Herein, we present histopathological characteristic of a case with MCA. Multiple cystic lesions and millimetric calculi with ectasia of the left kidney were detected by abdominal ultrasound and magnetic resonance imaging. Left simple nephrectomy was performed because of a pre-diagnosis of atrophic pyonephrotic kidney. The sections of the nephrectomized kidney revealed, multilocular mucinous cysts and histopathological appearance of MCA. We aimed to present this rare case mimicking atrophic cystic kidney with clinical, radiological findings, and histopathological characteristics in the lights of literature.J Clin Exp Invest 2015; 6(1: 78-80

    Full Text Available ABSTRACT: Double ureter is a result of premature division of t he ureteric bud. The ureters may join in the lower third of their course and open thr ough a common orifice into the bladder. If they open independently into the bladder, the ureter draining the upper pelvis opens into the bladder below the opening of the other ureter. Patie nts with double ureter or double pelvis are more likely to develop urinary infection and calculi .

    Sarcomatoid transitional cell carcinoma of the renal pelvis is a rare neoplasm with only 14 well-illustrated examples reported previously. Duplex kidney is the most common congenital abnormality of the urinary tract, with an incidence of around 2%. Neoplasia of the renal pelvis in duplex kidney is rare. We reported a case whose sarcomatoid carcinoma originated from the upper portion of the duplicated renal pelvis with hydronephrosis, and total nephroureterectomy with bladder cuff excision surgery of both renal units was carried out. Because of the rare nature of renal pelvic sarcomatoid carcinoma and its apparent lack of response to adjuvant therapy, it is essential to do early diagnosis and early radical surgery to improve survival. It is important to stress the need for frequent and diligent monitoring or treating complex duplex kidney with hydronephrosis of either moiety in case of a risk of having neoplasias.

  1. BILATERAL MULTIPLE RENAL VASCULAR VARIATIONS AND RIGHT SIDED BIFID URETER: A CASE REPORT

    2015-09-01

    Full Text Available Renal blood supply presents a large degree of variations. In the present case there was existence of bilateral variations in renal blood supply along with right sided bifid ureter. During routine cadaveric dissection in a middle aged male cadaver we found two renal veins draining right kidney and a bifurcating single renal vein on left side. On both sides one polar artery arising from main renal artery going to upper pole of kidney and left side accessory renal artery originating from abdominal aorta and giving origin to left testicular artery were observed. There is bifid ureter on the right side. The knowledge of renal vascular anatomy and its variations are very much essential in case of renal transplantation, renal surgeries, uroradiology, gonadal color Doppler imaging, in abdominal aortic aneurysmal and gonadal surgeries.

    Full Text Available PURPOSE: To demonstrate the feasibility of pure robotic retrocaval ureter repair. MATERIALS AND METHODS: A 33 year old female presented with right loin pain and obstruction on intravenous urography with the classical "fish-hook" appearance. She was counseled on the various methods of repair and elected to have a robot assisted repair. The following steps are performed during a pure robotic retrocaval ureter repair. The patient is placed in a modified flank position, pneumoperitoneum created and ports inserted. The colon is mobilized to expose the retroperitoneal structures: inferior vena cava, right gonadal vein, right ureter, and duodenum. The renal pelvis and ureter are mobilized and the renal pelvis transected. The ureter is transposed anterior to the inferior vena cava and a pyelopyelostomy is performed over a JJ stent. RESULTS: This patient was discharged on postoperative day 3. The catheter and drain tube were removed on day 1. Her JJ stent was removed at 6 weeks postoperatively. The postoperative intravenous urography at 3 months confirmed normal drainage of contrast medium. CONCLUSION: Pure robotic retrocaval ureter is a feasible procedure; however, there does not appear to be any great advantage over pure laparoscopy, apart from the ergonomic ease for the surgeon as well the simpler intracorporeal suturing.

  3. Endourological Evaluation and Management of Leukoplakia of the Renal Pelvis

    1996-01-01

    Full Text Available Since August 1989, we have seen 4 patients with leukoplakia of the renal pelvis associated with a longstanding renal stone. In 2 of them, excretory or retrograde pyelography revealed multiple filling defects in the left renal pelvis as well as a renal stone, although urine cytological examination was negative. One of the other 2 patients underwent extracorporeal shock wave lithotripsy (ESWL for the renal stone, but this was not followed by the passage of stone fragments. The renal stone in the remaining patient was associated with staghorn calculi. For stone extraction as well as endoscopic evaluation of the intrapelvic lesion, percutaneous nephroscopy was performed. A small to large amount of tissue-like white debris in sheets characteristic of leukoplakia was found in the renal pelvis with stones embedded in it and was removed directly by forceps or suction and then by irrigating with saline. We propose that 1 the endourological approach should be recommended for patients with renal pelvic lesions associated with longstanding renal stones or for patients who show difficulty in passing stone fragments after ESWL and 2 this entity of leukoplakia should be kept in mind for the differential diagnosis of renal pelvic lesions associated with renal stones.

    A common soft-tissue tumor, malignant fibrous histiocytoma (MFH) occurs in mainly limbs, retroperitoneal and peritoneal space, and occurrence in kidneys or the ureter is very rare. Dioctophyma renale (D. renale) since first discovered in dog's kidney was found in the kidneys of animals such as mink, coyote and weasel, and human infection has only been reported in only approximately 20 cases worldwide. MFH of the ureter and D. renale infection very rarely occur in humans, and has not been reported in our country. Here, we described the case of an adult man in whom MFH of the ureter simultaneously occurred with D. renale infection. An initial CT scan showed a well-defined, persistent, enhancing polypoid mass-like lesion in the upper ureter. After 10 months, D. renale was excreted in the urine and a follow-up CT scan showed an increase in the size of that lesion and irregular thickening of the ureter wall. The diagnosis of MFH was pathologically verified.

    Full Text Available Introduction. In males the ectopic ureter usualy drains into the prostate (50%. During ureteric developement a thin membrane (Chawalla’s membrane separates the lumen of the ureter and the urogenital sinus at the point where the ureter joins the urogenital sinus. This membrane ruptures allowing urin to drain from the ureter to the urogenital sinus. The authors reported a case of renal dysplasia associated with ipsilateral uretral ectopia mimicking prostatic abscess. Case report. A subfebrile (37.3°C, 23-year-old patient, otherwise healthy, presented with persistent ascending perineal pain non-responsive to antibiotics and analgetics. Digitorectal examination (DRE showed asymmetric prostate with a soft, tender, buldging left lobe suggestive of prostatic abscess. The diagnosis was suspected using transrectal ultrasonography (TRUS, but the picture of the anechoic tubular structure in the left lobe of the prostate with a proximal undefined extraprostatic extension and a caudal intraprostatic blind end was incoclusive for the definitive diagnosis of prostatic abscess. Magnetic resonance imaging (MRI was ordered and definitive diagnosis of renal dysplasia associated with the ipsilateral ectopic ureter filled with inflamed content mimicking prostatic abscess was made. Transurethral incision/minimal resection of the distal, blindly closed end of left ectopic ureter was done. Endoscopic surgical treatment was sufficient for relief of clinical symptoms. The patient’s recovery was uneventful. Conclusion. To the best of our knowledge, a case of renal dysplasia with the ipsilateral ectopic ureter mimicking prostate abscess has not been reported so far. Cystic pelvic malformations in males may result from too craniall sprouting of the ureteral bud, with delayed absorption and ectopic opening of the distal end of the ureter.

    An ultrasonographic reproductive health examination of a 26-yr-old female African elephant (Loxodonta africana) revealed bilateral ureteral wall thickening and dilatation. On ultrasonographic examination, the bladder and both ureters were normal near the trigone; however, the cranial-most aspect of each ureter was dilated and thickened for a length of 30-50 cm. The same month, elevated blood creatinine (3.0 mg/dl), and urine protein-creatinine ratio (4.0) were observed. Chronic renal failure was diagnosed based on these abnormalities, and the persistent ureteral dilatation was seen on subsequent ultrasound examinations. Complete blood cell counts, serum chemistries, and urinalyses remained relatively unchanged until 24 mo after diagnosis, at which time azotemia, hypophosphatemia, and hypercalcemia (including elevated ionized calcium) developed. Hydronephrosis of both kidneys and prominent sacculation of the left ureter were noted on ultrasonographic examination. Lethargy, ventral edema, and oral mucosal ulceration acutely developed 30 mo after diagnosis. Although blood urea nitrogen remained elevated, creatinine, total calcium, and ionized calcium returned to within reference ranges at that time. Due to rapid clinical decline and grave prognosis, humane euthanasia was elected. Bilateral ureteral dilatation, dysplasia of the right kidney, and chronic nephritis of the left kidney were identified postmortem.

    Longstanding renal calculus is a risk factor of squamous cell carcinoma (SCC) of the renal pelvis. It is highly aggressive and usually diagnosed at advanced stages with a poor prognosis. We present two cases of kidney stone complications with renal pelvic SCC. These two patients had a radical nephrectomy and the dissected tissues were renal pelvic SCC. Our cases further emphasize that renal pelvic SCC should be considered in patients with longstanding renal calculus. These cases contribute greatly to an early diagnosis and early treatment, both of which will significantly minimize the damage of, and markedly improve the prognosis of, renal pelvic SCC.

    Malignant neoplasms of the kidney represent about 2% of all cancers, being renal cell carcinoma the most frequent presentation in this group with a frequency of 80% to 90%. Adenocarcinoma of the renal pelvis is a rare neoplasm, which occurs in less than 1% of patients with renal malignancies and is associated, most of the times, to inflammatory processes of the organ and to renal stones. For all these reasons it was decided to publish a clinical case diagnosed in the Anatomical Pathology Department of the Dr. Gustavo Aldereguía Lima General University Hospital in Cienfuegos. A female patient over forty years old presented this histological variant of kidney cancer.

    Las neoplasias malignas del riñón representan alrededor del 2 % de todos los cánceres, el carcinoma de células renales es el más frecuente dentro de este grupo con una frecuencia del 80 al 90 %. El adenocarcinoma de pelvis renal es una neoplasia muy rara, que se presenta en menos del 1 % de los pacientes con neoplasias malignas renales, asociada, la mayoría de las veces, a procesos inflamatorios del  órgano y litiasis. Por tales razones se decidió la publicación de un caso clínico diagnosticado  en el Departamento de Anatomía Patológica del Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos, con esta variante histológica de cáncer renal, en una mujer en la cuarta década de la vida.

    IgG4-related disease is a recently recognized systemic disease characterized by storiform fibrosis with infiltration of IgG4-positive plasma cells. In rare incidences, IgG4-related renal disease can present as a solitary mass lesion at renal pelvis and can pose a diagnostic challenge since these lesions mimic malignancy. Herein, we present a rare case of IgG4-related disease presenting as inflammatory pseudotumor lesion, involving the renal pelvis and also neighboring renal parenchyma. A 75-year-old man with no history of IgG4-related disease underwent computed tomography (CT) scan for evaluation of prostatic cancer. The CT scan incidentally revealed a mass lesion located at the right renal pelvis. Radiologic findings were highly suggestive of malignancy. Therefore, the patient underwent right nephroureterectomy. Microscopically, the mass lesion showed storiform fibrosis with diffuse and intense inflammatory cell infiltration. Infiltrating cells were mainly histiocytes and plasma cells. Tubulointerstitium adjacent to the lesion also showed fibrosis with abundant plasmacytic infiltration. Immunohistochemical staining revealed the presence of IgG4-positive plasma cells in both the mass lesion and tubulointerstitium (mean of 94/HPF per field). Considering these findings, we diagnosed the mass lesion as IgG4-related inflammatory pseudotumor of the renal pelvis. In patients with renal pelvic masses, IgG4-related inflammatory pesudotumor should be considered in the differential diagnosis to avoid unnecessary surgical intervention.

    Full Text Available Background/Aim. Ureteropelvic junction obstruction and vesicoureteral reflux are the most frequent entities identified on the basis of antenatal hydronephrosis. The aim of this study was to determine the incidence and pattern of abnormal renal scintigraphy findings in postnatal investigation of children with antenatal hydronephrosis. Methods. Twenty four infants (19 boys and five girls presented with antenatal hydronephrosis and mild to moderate hydronephrosis on ultrasound in newborn period were referred for renal scintigraphy. Ten patients with vesicoureteral reflux documented on micturating cystoureterography underwent 99mTc-DMSA renal scintigraphy and 14 patients were subjected to 99mTc-DTPA scintigraphy. Results. Anteroposterior pelvic diameter on ultrasound ranged from 11 to 24 mm. Renal DMSA scans identified congenital scars in two boys with bilateral reflux of grade V and unilateral reflux of grade III. Relative kidney uptake (RKU less than 40% was found in three, and poor kidney function (RKU less than 10% in two patients. Significant obstruction was shown on DTPA diuretic renal scintigraphy in 6/14 patients. Some slowing in dranaige (T1/2 greater than 10 minutes with no reduction in differential renal function was identified in three patients. Differential renal function less than 10% was obtained in one case. Conclusion. A high percent of abnormal renal scintigraphy findings was obtained. Renal scintigraphy was useful in determination of underlying cause of antenatally detected hydronephrosis.

    Hernia through a defect of the broad ligament is extremely rare in children. These defects can result from a developmental defect or a spontaneous rupture of cystic formations remnants of mesonephric ducts or Müller. Genital anomalies associated with unilateral renal agenesis are more common in females. We report the case of a 13 months girl allowed for assessment of recurrent urinary tract infection; abdominal examination did not objectified palpable mass, the external genitalia were without abnormalities. Abdominal ultrasound revealed a left renal space is empty with a retrovesical cyst. Cystography was requested that objectified a large pelvic cystic mass retrovesical communicating with the bladder, there was also a left vesicoureteral reflux. Uro- MRI showed a cystic formation retrovesical communicating with the bladder, the right pelvic kidney; uterus is normal size for age. DMSA scintigraphy confirmed the absence of the left kidney with the right kidney that ensures 100% of total renal function. To surgical exploration we found a hernia of the bladder through the left broad ligament, the uterus was dislocated on the right side; left ovary was hypoplasic; the ipsilateral ureter was blind with renal agenesis, we performed by reduction of the bladder then closing the hernial orifice, dissection of the ureter with its ligation and section at the vesical stoma. The postoperative course was uneventful. Evolution is favorable. This observation illustrates a hernia of the bladder through the broad ligament associated with ovarian hypoplasia, renal agenesis and ipsilateral ureter blind ending; this association was not described to our knowledge in the literature.

    Full Text Available We present a rare case of an unobstructed dilated renal pelvis in a newborn female. Prenatal imaging documented a large abdominal cyst in a stable fetus. Postnatal imaging confirmed persistence of this large cyst but with an unclear etiology. The child was taken to surgery by the pediatric surgeons with concern for a possible harmful nonurologic diagnosis. Intraoperative findings were that of a severely dilated renal pelvis; however, in the absence of an expected ureteropelvic junction obstruction. Reduction pyeloplasty without interference of the ureteropelvic junction proved successful.

    Background Retrocaval ureter is a rare congenital abnormality.Operative repair is always suggested in cases of significant functional obstruction.Laparoscopic procedures have been employed as the minimally invasive therapeutic option for retrocaval ureter.However,the laparoscopic techniques for retrocaval ureter might be technically challenging to some surgeons.The aim of this article was to present our experience and surgical techniques of pure transperitoneal laparoscopic pyelopyelostomy and ureteroureterostomy in nine patients with retrocaval ureter.Methods A total of nine patients of retrocaval ureter underwent pure laparoscopic pyelopyelostomy or ureteroureterostomy.The operation was performed with the patients placed in the 70-degree lateral decubitus position via a three port transperitoneal approach with two 10-mm and one 5-mm ports.The distal part of the dilated renal pelvis was transected at the ureteropelvic junction and the ureter was relocated anterior to the inferior vena cava.The tension-free pyeloureteral or ureteroureteral anastomosis was completed with the intracorporal freehand suturing and in situ knot-tying techniques combined with interrupted and continuous fashion.A double J ureteral stent was inserted in an antegrade manner during laparoscopy.Intravenous urography or computerized tomography and renal ultrasonography were performed after 3 months postoperatively.Results All operations were completed laparoscopically,and no open conversion was required.The mean operative time was 135 minutes (range,70-250 minutes),with minimal blood loss (less than 60 ml).No intra-operative complications or significant bleeding occurred.All patients presented mild postoperative pain and quick convalescence.The symptoms disappeared and hydronephrosis decreased substantially after surgery.Conclusions Pure transperitoneal laparoscopic correction for retrocaval ureter was associated with an excellent outcome,minimal invasiveness and short hospital stay.It is

    pressure in the renal pelvis corresponded positively to the sensory ratings but the referred pain area was diffuse located and varied in size. The present study provides a method for describing the mechanosensory properties and 3D deformation of the complex renal pelvis geometry. Although...... there was a relation between pressure and pain score, the non-homogenous spatial strain distribution suggests that the 3D biomechanical properties of the renal pelvis are not reflected by simple estimates of tension based on pressure and volume....... for first sensation and for pain. 3D deformation and strain were calculated in five patients. The deformation of pelvis during distension was not uniform due to the complex geometry. The pelvis deformed to 113 ± 6% and 115 ± 11% in the longitudinal and circumferential directions, respectively. Endoluminal...

MRU is definitely the better investigation for the diagnosis of this condition as compared to the conventional radiological investigations. Laparoscopic nephroureterectomy is a very good procedure for the management of these cases.

  18. Overexpression of Heme Oxygenase-1 Prevents Renal Interstitial Inflammation and Fibrosis Induced by Unilateral Ureter Obstruction.

    Directory of Open Access Journals (Sweden)

    Xiao Chen

    Full Text Available Renal fibrosis plays an important role in the onset and progression of chronic kidney diseases. Many studies have demonstrated that heme oxygenase-1 (HO-1 is involved in diverse biological processes as a cytoprotective molecule, including anti-inflammatory, anti-oxidant, anti-apoptotic, antiproliferative, and immunomodulatory effects. However, the mechanisms of HO-1 prevention in renal interstitial fibrosis remain unknown. In this study, HO-1 transgenic (TG mice were employed to investigate the effect of HO-1 on renal fibrosis using a unilateral ureter obstruction (UUO model and to explore the potential mechanisms. We found that HO-1 was adaptively upregulated in kidneys of both TG and wild type (WT mice after UUO. The levels of HO-1 mRNA and protein were increased in TG mice compared with WT mice under normal conditions. HO-1 expression was further enhanced after UUO and remained high during the entire experimental process. Renal interstitial fibrosis in the TG group was significantly attenuated compared with that in the WT group after UUO. Moreover, overexpression of HO-1 inhibited the loss of peritubular capillaries. In addition, UUO-induced activation and proliferation of myofibroblasts were suppressed by HO-1 overexpression. Furthermore, HO-1 restrained tubulointerstitial infiltration of macrophages and regulated the secretion of inflammatory cytokines in UUO mice. We also found that high expression of HO-1 inhibited reactivation of Wnt/β-catenin signaling, which could play a crucial role in attenuating renal fibrosis. In conclusion, these data suggest that HO-1 prevents renal tubulointerstitial fibrosis possibly by regulating the inflammatory response and Wnt/β-catenin signaling. This study provides evidence that augmentation of HO-1 levels may be a therapeutic strategy against renal interstitial fibrosis.

    Full Text Available Carcinoma of the renal pelvis is an uncommon renal neoplasm. Clear cell adenocarcinoma in the urinary tract is rare and has a histomorphology resembling that of the female genital tract. We herein present a case of clear cell adenocarcinoma of the renal pelvis, which is the first example in a male patient to our knowledge. A 54-year-old man presented with right flank pain. The tumor was associated with renal stones and hydronephrosis and invaded into the peripelvic fat tissue with regional lymph node metastasis. The patient died of metastatic disease six months postoperatively. Histologically, the tumor showed complex papillary architecture lined with clear and hobnail cells. Clear cell adenocarcinoma of the renal pelvis may pose a diagnostic challenge on histological grounds, particularly in the distinction from renal cell carcinoma. The immunohistochemical stains could help confirm the diagnosis. Due to its rarity, an effective treatment regimen remains to be determined.

    Congenital giant megaureter (CGM) is uncommon in the pediatric population. The major clinical presentations are marked protruberances and abdominal cysts. We reported a case of CGM with almost the whole left ureter dilation accompanied with a 1 cm stricture at the entrance of the bladder and renal dysplasia, immediately compressing the contralateral ureter and causing bilateral hydronephrosis for the first time. At one-stage of the operation, a left nephrostomy with a right ureterolysis were performed, and a poor left kidney function was found. Then, the left kidney and ureter were cut off by nephroureterectomy at the second-stage. Eventually, the follow-up showed that the patient recovered well by abdominal ultrasound. Based on the findings of these reported literatures, CGM is rare. The physical and imaging examinations are essential for the diagnosis of CGM, and the appropriate treatment methods should be performed based on patients' specific condition.

    A case of primary adenocarcinoma of the renal pelvis occurring in a 57-year-old woman who had no previous history is reported. The lesions were thought to be a renal destruction by pyelolithiasis upon symptomatology and imaging study data. A nephrectomy was thus performed. Macroscopic examination revealed voluminous and exophytic lesions surrounding lithiasis. Diagnosis of intestinal-type adenocarcinoma of the renal pelvis was established on histological examination. No evidence of other tumor localization was revealed by complete exploration. Primary adenocarcinoma of renal pelvis is a rare and often mucinous intestinal-type tumour. Chronic inflammation and renal lithiasis seem to be associated with this tumour. Few cases are reported and prognosis is doubtful. The main differential diagnosis to eliminate is secondary lesions to the kidney of adenocarcinoma from another origin. A careful pathological examination in case of pyelonephritic kidney is necessary to look for an associated tumour.

    Single system ureteral ectopia and associated congenital dysplastic kidney is surgically curable etiology of incontinence with other wise normal pattern of voiding in female child. We share our experience of eight cases in last one year and its management with laparoscopic nephroureterectomy at a tertiary care hospital in India which is one of the largest series in such a short duration of this rare anomaly. Materials and Methods: Patients presented with clinical features of continence with otherwise normal pattern of voiding were clinically examined and investigated by ultrasound (USG), nuclear renal scan, magnetic resonance urography (MRU). Laparoscopic nephroureterectomy was done in all the eight cases and renal dysplasia was confirmed on histological examination. Results: All the patients were females in the age group of five months to five years. USG detected the renal dysplasia in three out of eight cases; however, it could not detect the course of the ectopic ureter in any of the cases. MRU picked up the dysplastic moieties and their location as well as functional status and also depicted the course of the ectopic ureter opening into the vaginal wall in all the eight cases. Laparoscopic nephroureterectomy was done in all the cases and patients were cured off their symptoms. Conclusion: Single system ectopic ureter associated with congenital renal dysplasia is exceedingly rare. MRU is definitely the better investigation for the diagnosis of this condition as compared to the conventional radiological investigations. Laparoscopic nephroureterectomy is a very good procedure for the management of these cases. PMID:19955670

    Full Text Available We aimed, in this study, to determine the distribution of α-1 AR subtypes in rat and human pelvis and calyces, and to evaluate, by comparing these two species, the possibility of rats to be used as models for humans. Twenty patients with renal carcinoma were included into the study. The patients underwent radical nephrectomy for renal cell carcinoma (RCC. After nephrectomy, specimens were evaluated and excisional biopsies from healthy pelvis and calyces tissues were performed. When pathology confirmed the non-invasion of RCC, specimen was included into the study. A total of 7 adult Wistar Albino (250-300 g female rats were used in this study. Specimens included renal pelvis and calyces. All specimens were evaluated under light microscope histopathologically. The concentrations of the receptor densities did not differ between the two groups. With the demonstration of the α receptors in rat kidneys and calyces, many receptor-based studies concerning both humans and rats can take place. Novel medication targeting these subtypes -in this matter α1A and α1D for renal pelvis and calyces- may be helpful for expulsive therapy and/or pain relief. With the demonstration of similar receptor densities between human and rat tissues, rat model may be useful for α-receptor trials for renal pelvis and calyces.

    Spontaneous rupture of renal pelvis with urine extravasation is a rare condition and usually associated with obstructing ureteric calculus. It poses diagnostic and therapeutic dilemmas, while a stepwise approach for the confirmation of diagnosis, treatment and follow up is needed. We present a case of a 75-year old male patient who had a renal pelvis rupture with perirenal extravasation of urine due to a 4 mm stone located at the right ureterovesical junction. Diagnosis was confirmed by computed tomography, while the patient was treated successfully with the placement of a percutaneous nephrostomy. A week later a CT- nephrostomography showed the healing of renal pelvis with no extravasation and no evidence of the obstructing stone.

    Human primary epithelial cells of renal pelvis was established to investigate the adherence of uropathogenic Escherichia coli (UPEC) to this cell line, in which the primary cell culture was performed by using cultivation of the normal epithelium of renal pelvis in keratinocyte serum free medium (K-SFM)with epidermal growth factor (EGF) and bovine pituitary extract (BPE). Both UPEC132 obtained from urine specimen of patients with pyelonephritis and the pilus-free representative strain E. coli K-12p678-54 were used to study the adherence of these strains on human primary epithelial cells of renal pelvis.The UPEC adherence was performed with observation on the morphological changes of the adhered cells,while the adhesion rates and indices were calculated in different times of experiment. In addition, the virulence genes hly and cnf1 of UPEC132 were detected by multiplex PCR assay. In this study, the human primary epithelial cells of renal pelvis was found to exhibit the character of the transitional epithelial cells. Compared with the control group, the adhesion rates and indices began to increase from 15 min of the experiment time and reached its peak in 120 min. The adhesion rate and index of UPEC132 to human primary epithelial cells of renal pelvis were 74.4% and 34.0 respectively. Many microscopic changes in the primary cells adhered with UPEC132 could be detected, such as rounding or irregularity in shape,unevenness in staining and the cytoplasmic and nuclear changes. It suggests that human primary epithelial cells of renal pelvis can be used for the experiment on UPEC adhesion, thus providing a basis for the further study on the pathogenesis of UPEC.

    An immunohistochemical and western blot expression analysis of human ureters was performed in order to characterize the alpha-1-adrenergic receptor distribution along the length of the human ureteral wall. Mapping the distribution will assist in understanding the potential role alpha -1-adrenergic receptors and their subtype density might have in the pathophysiology of ureteral colic and stone passage. Patients diagnosed with renal cancer or bladder cancer undergoing nephrectomy, nephroureterectomy, or cystectomy had ureteral specimens taken from the proximal, mid, distal and tunneled ureter. Tissues were processed for fresh frozen examination and fixed in formalin. None of the ureteral specimens were involved with cancer. Serial histologic sections and immunohistochemical studies were performed using antibodies specific for alpha-1-adrenergic receptor subtypes (alpha 1a, alpha 1b, alpha 1d). The sections were examined under a light microscope and scored as positive or negative. In order to validate and quantify the alpha receptor subtypes along the human ureter. Western blotting techniques were applied. Human ureter stained positively for alpha -1-adrenergic receptors. Immunostaining appeared red, with intense reaction in the smooth muscle of the ureter and endothelium of the neighboring blood vessels. There was differential expression between all the receptors with the highest staining for alpha-1D subtype. The highest protein expression for all three subtypes was in the renal pelvis and decreased with advancement along the ureter to the distal ureter. At the distal ureter, there was marked increase in expression as one progressed towards the ureteral orifice. The same pattern of protein expression was exhibited for all three alpha -1-adrenergic receptor subtypes. We provide preliminary evidence for the ability to detect and quantify the alpha-1-receptor subtypes along the human ureter which to the best of our knowledge has never been done with

    2005-10-01

    To test the hypothesis that activation of the vanilloid receptor 1 (VR1) expressed in sensory nerves innervating the renal pelvis leads to diuresis and natriuresis, a selective VR1 receptor agonist, capsaicin (2.4 nmol), or vehicle was perfused intravenously or into the left renal pelvis of anesthetized rats at a rate without changing renal perfusion pressure. Mean arterial pressure was not altered by capsaicin administered intravenously or into the renal pelvis. Capsaicin perfusion into the left renal pelvis but not intravenously caused significant increases in urine flow rate and urinary sodium excretion bilaterally in a dose-dependent manner, which were abolished by capsazepine, a selective VR1 receptor antagonist, given ipsilaterally to the renal pelvis or by ipsilateral renal denervation. Capsaicin given intravenously or into the left renal pelvis increased plasma calcitonin gene-related peptide levels to the same extent. Increased plasma calcitonin gene-related peptide levels induced by capsaicin (68.9+/-2.8 pg/mL) perfusion into the renal pelvis was prevented either by capsazepine (22.5+/-10.1 pg/mL) given ipsilaterally into the renal pelvis or by ipsilateral renal denervation (25.9+/-2.3 pg/mL). Taken together, our data show that unilateral activation of VR1-positive sensory nerves innervating the renal pelvis leads to bilateral diuresis and natriuresis via a mechanism that is independent of plasma calcitonin gene-related peptide levels. These data suggest that VR1-positive sensory nerves in the kidney enhance renal excretory function, a mechanism that may be critically involved in sodium and fluid homeostasis.

    Full Text Available Abstract Introduction Congenital renal arteriovenous malformations (AVMs are very rare benign lesions. They are more common in women and rarely manifest in elderly people. In some cases they present with massive hematuria. Contemporary treatment consists of transcatheter selective arterial embolization which leads to resolution of the hematuria whilst preserving renal parenchyma. Case presentation A 72-year-old man, who was heavy smoker, presented with massive hematuria and flank pain. CT scan revealed a filling defect caused by a soft tissue mass in the renal pelvis, which initially led to the suspicion of a transitional cell carcinoma (TCC of the upper tract, in view of the patient's age and smoking habits. However a subsequent retrograde study could not depict any filling defect in the renal pelvis. Selective right renal arteriography confirmed the presence of a renal AVM by demonstrating abnormal arterial communication with a vein with early visualization of the venous system. At the same time successful selective transcatheter embolization of the lesion was performed. Conclusion This case highlights the importance of careful diagnostic work-up in the evaluation of upper tract hematuria. In the case presented, a congenital renal AVM proved to be the cause of massive upper tract hematuria and flank pain in spite of the initial evidence indicating the likely diagnosis of a renal pelvis tumor.

    Carcinosarcomas are rare biphasic malignant neoplasms with epithelial and a spindle cell component. We present a 62-year-old man with a history of noticeably abdominal distension, proved by surgery to be caused by carcinosarcoma of the renal pelvis and urinary bladder, occupying the entire left abdominal flank. We also illustrate the appearance of this rare entity on sonography and computed tomography.

    Partial spontaneous rupture of the upper urinary tract is rare and usually associated with nephrolithiasis. Other reported causes, apart from instrumentation and trauma, involve obstructive ureteral tumor in the pelvic cavity, retroperitoneal fibrosis, fluid overload, and pregnancy. We report a case of spontaneous rupture of renal pelvis secondary to ureteral obstruction caused by urothelial tumor, clinically suspected and evaluated by CT scans and MRIs, discussing the relevant findings for diagnosis.(author)

    Motility of ureter. Changes of secretion-phase during sequential scintigraphy of the kidneys under the influence of Metamizol - a parameter to study the effect of Metamizol: The aim of the study is to get quantitative information about the effect of Metamizol (Novalgin) on the motility of the ureter. We compared the renal excretion of 99m-Tc-MDP (Tecebon) and the extent of flowing off towards gravity through the ureter with and without Metamizol. The effect of Metamizol is shown in comparing the final amplitudes of nephrograms recorded during sequential scintigraphy of the kidneys and comparing the integrals of these curves before and after injection of Metamizol. It can be demonstrated that the flow off towards gravity through the ureter is significantly diminished under Metamizol caused by its spasmolytic effect.

    We performed construction of continent urinary reservoir in an 8-year-old girl with cloacal exstrophy who had double stoma of ileostomy and colon conduit. Preoperative evaluation revealed non-functioning right kidney with severely dilated renal pelvis and calyxes in her pelvis. Urinary reservoir was constructed using detubularized colon segment which had been used as the urinary conduit and dilated renal pelvis of non-functioning pelvic kidney. Using Mitrofanoff's principle, continent catheterizable channel was also made of the anterior wall of the renal pelvis. Postoperative course was uneventful. Reservoir capacity increased to 350 ml one and half year postoperatively and she is almost dry with clean intermittent catheterization 5 times a day. Dilated upper urinary tract is one of the ideal material for bladder enlargement that avoids the complication associated with the use of gastrointestinal tract.

    A 68-year-old woman was found incidentally to have right hydronephrosis and a renal pelvic mass by abdominal ultrasonography. Radiographic examinations revealed a heterogeneous renal pelvic tumor, and right nephroureterectomy was performed. The tumor was well circumscribed yellow-whitish solid mass with scattered cysts. Histologically, the tumor was composed of both mesenchymal and epithelial components. The mesenchymal elements consisted of fibroblasts and smooth muscle cells, and the epithelial elements of cystic and tubular structures lined by cuboidal epithelium. Atypia and mitoses were not identified. The patient was free of recurrence 42 months postoperatively. Mixed epithelial and stromal tumor of the kidney is a recently recognized neoplasm that occurs almost exclusively in perimenopausal woman. Similar tumors have been reported previously under various names, including adult mesoblastic nephroma and cystic hamartoma of the renal pelvis. Histogenesis of the tumor is still controversial.

    Full Text Available Purpose. It was to quantify the intraobserver and interobserver variability of the sonographic measurements of renal pelvis and classify hydronephrosis severity. Methods. Two ultrasonographers evaluated 17 fetuses from 23 to 39 weeks of gestation. Renal pelvis APD were taken in 50 renal units. For intraobserver error, one of them performed three sequential measurements. The mean and standard deviation from the absolute and percentage differences between measurements were calculated. Bland-Altman plots were used to visually assess the relationship between the precision of repeated measurements. Hydronephrosis was classified as mild (5.0 to 9.9 mm, moderate (10.0 to 14.9 mm, or severe (≥15.0 mm. Interrater agreement were obtained using the Kappa index. Results. Absolute intraobserver variation in APD measurements was 5.2±3.5%. Interobserver variation of ultrasonographers was 9.3±9.7%. Neither intraobserver or interobserver error increased with increasing APD size. The overall percentage of agreement with the antenatal hydronephrosis diagnosis was 64%. Cohen's Kappa to hydronephrosis severity was 0.51 (95% CI, 0.33 to 0.69. Conclusion. Inter and intraobserver APD measurement errors were low in these group, but the agreement to hydronephrosis diagnosis and classification was fair. We suggest that standard and serial APD measurement can better define and evaluate fetal hydronephrosis.

    Full Text Available We report a case of granulocyte-colony stimulating factor (G-CSF producing infiltrating urothelial carcinoma of the left renal pelvis. The patient was referred to our hospital for fever and anorexia. Blood tests showed elevated level of leukocytosis without any infectious diseases. The serum concentration of G-CSF was remarkably elevated. Abdominal computed tomography (CT revealed a huge mass in the left renal pelvis and para-aortic lymph node enlargement. He was underwent left nephroureterectomy and para-aortic lymphadenectomy. The histological examination revealed infiltrating urothelial carcinoma with positive staining for G-CSF antibody. The postoperative course was smooth and the leukocyte count became normalized within a week postoperatively. However, multiple lung metastasis and leukocytosis were revealed about 2 months after the operation. G-CSF producing infiltrating urothelial carcinoma of the renal pelvis is reported to have a significantly poor prognosis, so it is very important to monitor closely after the operation.

    Full Text Available Background. The objective of this paper was to examine the epidemiology, natural history, and prognostic factors of carcinosarcoma of the kidney and renal pelvis (CSKP using population-based registry. Patients and Methods. Forty-three patients with CSKP, diagnosed between January 1973 and December 2007, were identified from the national Surveillance, Epidemiology, and End Results (SEER database and reviewed. Results. 79% of all patients with known SEER stage were classified as having regional or distant stage; almost all the patients with known histology grade had poorly or undifferentiated histology. The median cancer specific survival was 6 months (95% CI 4–9. The 1-year cancer-specific survival rate for entire cohort was 30.2%. There were no differences in terms of age at diagnosis, histological grade, tumor stage on presentation, and frequency of nephrectomy between carcinosarcoma of kidney (CSK or renal pelvis (CSP. In multivariate analysis, age at diagnosis, tumor stage, and year of diagnosis were found to be significant predictors for cancer-specific survival. Conclusion. CSKP commonly presented as high-grade, advanced stage disease, and was associated with a poor prognosis regardless of location.

    Full Text Available The study was carried at two different centres. Only 9 cases of primary malignant tumours of the renal pelvis could be collected during the period of 7 years (1984-1990. Renal pelvis malignancies constituted 0.21% of all the malignancies and 12.16% of all the malignant growths of the kidney (9 out of 74 cases. The age of these patients ranged from 24 to 70 years; the mean being 41.7 years. Male/female ratio was 8:1. Common triad of complaints (pain, haematuria and lump was noticed in 22.2% of patients. Individually they were noticed in 77.8%, 66.7% and 44.4% of patients respectively. Transitional cell carcinoma was the commonest, seen in 7 patients (77.8% whereas squamous cell carcinoma and adenocarcinoma were noticed in one patient (11.1% each. Hydronephrosis, chronic pyelonephritis and nephrolithiasis were noticed in 66.7%, 44.4% and 22.2% of patients respectively. Ultrastructural study of urothelial tumours revealed tumour cells in various stages of differentiation with loss of intercellular junctions and dense collection of rough endopasmic reticulum fibrils around the nucleus.

    We report an extremely rare case of a pancake kidney with a single ureter. During the medicolegal autopsy on the body of a traffic accident victim, the kidneys were not located in the abdomen. The anterior surfaces of both kidneys were completely fused in the pelvic cavity, and the kidney was shaped like a pancake. This pancake kidney had accessory renal arteries around it and one renal vein from each kidney. The left renal vein was much smaller in diameter than the right one. There were two major calyces, one each from each kidney. The major calyces joined to form a single renal pelvis from both the kidneys, which continued as a single ureter. The renal pelvis and ureter lay posterior to the pancake kidney. Urologists and pelvic surgeons should be aware of the variant anatomy of the pancake kidney, particularly concerning its vasculature, to prevent unexpected catastrophic bleeding. If the kidneys are not located in the abdominal cavity, the autopsy surgeon must consider the possibility of its presence in the pelvic cavity. This could be especially important during medicolegal investigations into allegations of missing kidneys and unlawful kidney transplantations.

    Viprakasit, Davis P.; Macejko, Amanda M.; Nadler, Robert B.

    2009-01-01

    Laparoscopic nephroureterectomy (LNU) is becoming an increasingly common alternative treatment for transitional cell carcinoma (TCC) of the renal pelvis and ureter due to decreased perioperative morbidity, shorter hospitalization, and comparable oncologic control with open nephroureterectomy (ONU). Mobilization of the kidney and proximal ureter may be performed through a transperitoneal, retroperitoneal, or hand-assisted approach. Each technique is associated with its own benefits and limitations, and the optimal approach is often dictated by surgeon preference. Our analysis of the literature reflects equivalent cancer control between LPN and OPN at intermediate follow-up with significantly improved perioperative morbidity following LPN. Several methods for bladder cuff excision have been advocated, however, no individual technique for management of the distal ureter proved superior. Overall, complete en-bloc resection with minimal disruption of the urinary tract should be optimized to maintain oncologic outcomes. Longer follow-up and prospective studies are needed to fully evaluate these techniques. PMID:19148293

    Full Text Available Primary squamous cell carcinoma (SCC of the renal pelvis is a very rare tumor often associated with renal calculi and chronic infections. There are only a few articles in literature which report renal pelvis SCC in kidneys treated for renal tuberculosis, diagnosed after nephrectomy. We report the case of SCC in a hydronephrotic kidney previously treated for tuberculosis, diagnosed by ultrasound (US-guided fine-needle aspiration cytology (FNAC, prior to core biopsy and nephrectomy. Our report highlights the utility of FNAC and the need for a careful search for renal collecting system tumors, in patients previously treated for renal tuberculosis.

    Full Text Available Primary Squamous Cell Carcinoma in the kidney is a rare malignant neoplasm associated with nephrolithiasis, typically monobacterial pyonephrosis and rarely Xanthogranulomatous pyelonephritis. It is an aggressive disease with a poor prognosis mostly due to lack of presenting clinical features like a palpable mass, gross haematuria and pain. We report a case presenting with renal calculus and pyonephrosis managed initially with percutaneous nephrostomy followed by nephrectomy due to complete loss of renal function. Histopathological evaluation revealed poorly differentiated squamous cell carcinoma which is managed by chemotherapy, although initially beneficial, patients later develop disseminated metastatic disease which holds a poor prognosis.

    [Objective] To explore the CT diagnosis and the reason of missed diagnosis of kidney calculi with renal pelvis malignant tumor. [Methods] The CT data of 9 cases of kidney calculi with renal pelvis malignant tumor confirmed by pathology were analyzed retrospectively. The site of pathogenesis, histological type, metastasis, complication and the relation with the surrounding tissue were observed. [Results] Among 9 cases of kidney calculi with renal pelvis malignant tumor, 5 cases were transitional cell carcinoma, 3 cases were squamous cell carcinoma and 1 case was adenocarcinoma. Retroperitoneal lymph node metastasis was found in 5 cases including one case of adenocarcinoma and one case of transitional cell carcinoma involving the metastasis of renal capsule and adjacent adipose tissue, liver and adrenal gland. Seven cases were combined with the inflammation of renal pelvis and ureter or pyonephrosis. Three cases were combined with inflammatory granulation of renal pelvis. Two cases of transitional cell carcinoma and one case of cases of squamous cell carcinoma were misdiagnosed as kidney calculi with hydronephrosis infection. The definite diagnosis rate was 66. 7% (6/9) and the misdiagnosis rate was 33. 3% (3/9). [Conclusion] Multi-slice CT for kidney calculi with renal pelvis malignant tumor has higher diagnostic value. However, kidney calculi with renal pelvis accompanied by other lesions are easy to be misdiagnosed.%[目的]探讨肾结石并肾盂恶性肿瘤的CT诊断和漏诊原因.[方法]回顾性分析经手术病理证实的9例肾结石并肾盂恶性肿瘤的CT资料,重点观察肾结石并肾盂恶性肿瘤的发生部位、病理类型、有无转移、合并症及与周围组织关系.[结果]9例肾结石并肾盂恶性肿瘤患者5例为肾盂移行细胞癌,3例为肾盂鳞癌,1例腺癌;5例有腹膜后淋巴结转移,鳞癌、移行细胞癌各1例,累及肾被膜及邻近脂肪组织及肝、肾上腺等多处转移;7例合并肾盂、

    To establish a threshold value for fetal renal pelvis dilatation measured by automatic volume calculation (SonoAVC) in the third trimester of pregnancy to predict neonatal uropathies, and to compare these results with conventional antero-posterior (AP) measurement, fetal kidney 3D volume and renal parenchymal thickness. In a prospective cohort study, 125 fetuses with renal pelvis AP diameter of ≥5 mm both at 20 weeks of gestation and in the third trimester, underwent an additional 3D volume measurement of the fetal kidney in the third trimester. Receiver operating characteristic (ROC) curves for establishing threshold values for fetal renal pelvis volume, AP measurement, fetal kidney volume and renal parenchymal thickness to predict neonatal uropathies were analyzed. Also, sensitivity, specificity, area under the curve (AUC) and likelihood ratios were calculated. A cut-off point of 1.58 cm³ was identified in the third trimester of pregnancy (AUC 0.865 (95% CI 0.789-0.940), sensitivity 76.3%, specificity 87.4%, LR+ 6.06, LR- 0.27) for measurements with SonoAVC. A cut-off value of 11.5 mm was established in the third trimester of pregnancy (AUC 0.828 (95% CI 0.737-0.918), sensitivity 71.1%, specificity 85.1%, LR+ 4.77, LR- 0.34) for the conventional AP measurement. A cut-off point for fetal kidney volume was calculated at 13.29 cm³ (AUC 0.769 (95% CI 0.657-0.881), sensitivity 71%, specificity 66%, LR+ 2.09, LR- 0.44). For renal parenchymal thickness, a cut-off point of 8.4 mm was established (AUC 0.216 (95% CI 0.117-0.315), sensitivity 31.6%, specificity 32.6%, LR+ 0.47, LR- 2.10). This study demonstrates that 3D fetal renal pelvis volume measurements and AP measurements both have a good and comparable diagnostic performance, fetal renal volume a fair accuracy and renal parenchymal thickness a poor accuracy in predicting postnatal renal outcome.

    Full Text Available Blunt rupture of the renal pelvis is a exceedingly rare injury. Hematuria is absent in one-third of cases. Such injuries are usually caused by desacceleration forces. Despite improved imaging techniques, diagnosis of this injuries is frequently delayed. Diagnosis is suggested by the presence of massive medial extravasation of contrast material at excretory urography or computed tomography. Surgical treatment consists in pyeloplasty or pyeloraphy with stent placement (double J or nephrostomy.

Both neoplasms were similar in size and appeared symmetrical. Despite its small size, the medullary carcinoma metastasized in multiple cervical lymph nodes. The second patient had a high-grade invasive papillary urothelial carcinoma of the renal pelvis that infiltrated the renal parenchyma and metastasized in one of the lungs. Five months later, a papillary carcinoma was discovered in the thyroid gland. The 2 papillary thyroid carcinomas were of the follicular variant. Adjacent to 1 papillary carcinoma, there was a dominant nodule of a colloid and adenomatous goiter. The medullary carcinoma contained stromal amyloid and was immunoreactive for calcitonin and carcinoembryonic antigen. There was no C-cell hyperplasia (medullary carcinoma in situ). The 2 patients are alive, 1 is living with pulmonary metastasis from the high-grade urothelial carcinoma. Twelve cases of this neoplastic association were registered in the Survey, Epidemiology, and End Results Program from 1980 to 2009. We believe that the combination of these unusual neoplasms in the same patient may represent a new sporadic neoplastic syndrome.

    Full Text Available Sarcomatoid carcinoma is a rare malignant tumor that has both malignant epithelial and mesenchymal components. We describe a sarcomatoid carcinoma arising in the left renal pelvis of a 49-year-old man. The dominant component of the tumor was chondrosarcomatous, but there were also focal carcinomatous areas. The carcinomatous tumor cells consisted of papillary urothelial carcinoma. Immunohistochemical assay showed that the sarcomatous tumor cells were positive for vimentin and S 100 and negative for cytokeratin. The papillary urothelial carcinoma was positive for cytokeratin and negative for vimentin. The patient underwent neoadjuvant chemotherapy and after downsizing the tumor, radical nephrectomy was performed with excision of the cuff of bladder.

    Full Text Available Retrocaval ureter is one of the very rare congenital anomalies. We report a case of retrocaval ureter in a 6-year-old girl who presented with right flank pain and hydronephrosis. The diagnosis was made on intravenous urography which showed typical “J” shape deformity in the proximal dilated ureter with moderate hydronephrosis. CT scan delineated the course of ureter. The patient was operated and findings were confirmed. The ureter was transected near the pelvis and a pyeloureteric anastomosis with pre-caval transposition of the ureter was performed and the patient was discharged in fair health.

    Full Text Available Researches of the capabilities of radionuclide diagnosis are one of the most important trends in modern medical science and practice, especially in the area of dynamic renal scintigraphy. This technique proved to be safe and highly informative when used in oncogyne- cology to evaluate defects of renal drainage. However, failure to make an objective evaluation of ureteral patency reduces significant- ly the capabilities of the technique in patients after small pelvis surgery and radiotherapy. The study issues presented in this article are devoted to this particular problem. The authors have developed an original procedure for evaluating renal drainage disorders during dynamic renal scintigraphy. The specific visual and digital parameters which characterize both normal and obstructed urine outflow in the supravesical segment are given. Criteria for serious disorders in urine derivation from the kidneys through the ureters are defined. Risk factors for urine outflow disorders are identified in cervical cancer patients who receive various treatments.

    The aim of the present study was to assess the morbidity of ampullary renal pelvis (ARP) and document its natural history in post-natal life. A total of 1,167 newborn infants with prenatally suspected hydronephrosis were retrospectively analyzed. Of these, 65 patients were diagnosed with ARP by computed tomography urography (CTU) and/or magnetic resonance urography (MRU). All cases were followed up with ultrasonogrophy at 1, 3, 6 and 12 months after birth, and one case was followed up for 5 years. Changes in the separation of the renal pelvis collection system were recorded. Children with ARP accounted for 5.57% of the total cases (65/1,167) followed-up. No lack of connection between the renal calyces and the renal pelvis was detected. The long-term follow-up revealed that the separation of the renal pelvis collection system did not tend to increase over time. In addition to imaging examinations, long-term follow-up observation is recommended for the accurate diagnosis of pediatric ARP, particularly for differentiation from hydronephrosis.

    Full Text Available Background: The objective of the following study is to determine and to compare the different morphological parameters with duration of obstruction created experimentally in unilateral upper ureters of rats. Materials and Methods: Unilateral upper ureteric obstruction was created in 60 adult Wistar rats that were reversed after predetermined intervals. Rats were sacrificed and ipsilateral kidneys were subjected for analysis of morphological parameters such as renal height, cranio-caudal diameter, antero-posterior diameter, lateral diameter, volume of the pelvis and average cortical thickness: Renal height. Results: Renal height and cranio-caudal diameter of renal pelvis after ipsilateral upper ureteric obstruction started rising as early as 7 days of creating obstruction and were affected earlier than antero-posterior and lateral diameter and also were reversed earlier than other parameters after reversal of obstruction. Renal cortical thickness and volume of the pelvis were affected after prolonged obstruction (> 3 weeks and were the late parameters to be reversed after reversal of obstruction. Conclusions: Cranio-caudal diameter and renal height were the early morphological parameters to be affected and reversed after reversal of obstruction in experimentally created ipsilateral upper ureteric obstruction.

    Full Text Available Introduction. Xanthogranulomatous pyelonephritis (XGP is a type of chronic renal inflammation that usually occurs in immunocompromised middle-aged women with chronic urinary tract infection or ureteral obstruction induced by the formation of ureteral stones. XGP with an incomplete double ureter is extremely rare. Case Presentation. A 76-year-old woman was referred to our department to undergo further examination for a left renal tumor that was detected by ultrasonography. Dynamic contrast computed tomography (CT revealed an enhanced tumor in the upper renal parenchyma. Laparoscopic radical nephrectomy was performed based on a preoperative diagnosis of renal cell carcinoma. Histological sections showed the aggregation of foam cells; thus, XGP was diagnosed. Conclusion. We herein report a rare case of XGP in the upper pole of the kidney, which might have been associated with an incomplete double ureter.

    2011-01-01

    We report a 12-year-old male child with an unusual cause of abdominal pain, i.e. a blind-ending ureter with vesicoureteral reflux. The pain improved with antibiotic therapy, implying infection as the cause of pain. This entity is difficult to diagnose clinically, thereby affecting management. Usually, a blind-ending ureter is not filled on intravenous urography (IVU) and the diagnosis is confirmed by retrograde pyelography, which is an invasive procedure. We illustrate the contribution of IVU and computerized tomographic cystography, which has not been reported earlier, in the evaluation of such cases. PMID:21747603

    2012-01-01

    A female patient from a remote village and poor socioeconomic background presented to our clinic with abdominal pain at the right flank. She had a history of endoscopic double J stent placement four years prior. However, the details were not available, as neither the patient nor her relatives were aware of the history. An ultrasonography was performed and revealed moderate hydronephrosis of the right kidney with two calculi measuring 2.9 cm at the pyeloureteral junction (PUJ), a 2.6 cm calculus in the renal pelvis, and a 4 cm vesicle calculus. An intravenous urography revealed delayed excretion of contrast medium in the right kidney. A cystoscopy was then performed and the lower end of the forgotten double J stent was cut along with the encrusted stone in bladder [1, 2]. Removal of the large encrusted bladder stone was aided by lithotripsy. This was followed by the removal of the two PUJ calculi and the remaining portion of the encrusted double J stent, which was extracted with relative ease via a right-sided open pyelolithotomy [3]. The post-operative course was uneventful and her kidney function test was absolutely normal following the procedures. The patient was found to be stone-free and was discharged home. In light of this situation we have deemed it necessary to maintain contact and ensure regular follow-up visits for patients with double J stent placements in order to avoid such dangerous complications in the future. By following this custom, we aim to reduce the patient morbidity and avoid any unnecessary inconvenience. PMID:24578973

  1. Giant Ectopic Ureter Mimicking Pelvic Organ Prolapse: A Case Report

    Directory of Open Access Journals (Sweden)

    Adnan Simsir

    2011-01-01

    Full Text Available Ectopic ureter is one of the most common urinary tract anomalies. We, herein, present a case of a giant ureter with ectopic orifice, mimicking pelvic organ prolapse, which is the first in the literature. A 59-year-old female patient presenting with frequently recurrent urinary tract infection had grade 3 pelvic organ prolapse. On examination, the organ producing the appearance of prolapse was found to be a right ureter of giant size and was obstructed by a large stone at the distal segment. The proximal end of the ureter ended blindly. After exploration, the stone was removed, the ureter was detached from the urethra, and the lumen was tied off and cut 5 cm proximally. At 6 months postoperatively, the patient is being followed up without any clinical problems. In such cases with nonfunctioning renal segment draining proximally, the chance of cure can be obtained without a need for a comprehensive intervention such as total abdominal ureterectomy.

    Objective To review the diagnosis and treatment of squamous cell carcinoma of renal pelvis. Methods The clinical data from October 1991 to May 2009 of eight cases of squamous cell carcinoma of renal pelvis were reviewed and analyzed retrospectively. The symptoms of the patients were hematuria (eight cases), pain (seven cases) and abdominal mass (one case). All patients underwent B-ultrasound and IVU examination and four cases underwent CT scan. Three cases were diagnosed as having a tumor before surgery. Five cases were diagnosed as renal calculus, two of the five cases were diagnosed by intraoperative frozen section. Radical nephroureterectomy were performed in four cases, nephrectomy in three cases and palliative resection in one case. Results Histological classification revealed that six cases were moderately differentiated, one case was well differentiated and one case was poorly differentiated. Two cases had stage pT1/pT2 and six cases had stage pT3/pT4. 2 cases had regional lymph nodes metastasis. Seven cases were followed-up. All patients died of tumor recurrence or metastasis. The median tumor specific survive time was six months (range from two months to 42 months). Conclusions Squamous cell carcinoma of renal pelvis is often occurs concurrently with urolithiasis which could lead to difficulty in diagnose before operation. As the most of the patients were diagnosed with advanced stage disease, squamous cell carcinoma of renal pelvis tended to early recurrence and metastasis and the prognosis was very poor.%目的 探讨肾盂鳞状细胞癌的诊治特点.方法 回顾性分析1991年10月至2009年5月收治8例肾盂鳞状细胞癌患者资料.临床表现血尿8例,腰痛7例,腹部包块1例.B超检查8例,IVU检查8例,CT检查4例.术前诊断为肿瘤3例,诊断为肾结石5例,结石术中发现肿瘤并经冰冻病理确诊2例.8例患者均经手术治疗,行根治性肾输尿管切除4例、单纯性肾切除3例、姑息性切除术1

    Retroiliac ureter is a rare condition where the ureter passes behind the iliac vessels. The diagnosis is usually intraoperative and the reports of preoperative imaging diagnosis are scarce. Herein, we report the computed tomography appearance of a unique variant in which the right ureter partially encircles the right common iliac artery bifurcation; passing first in front of the common iliac artery and then medial to the artery and finally posterior to the external iliac artery, and then regains its normal course in the pelvis.

  7. Robot-assisted pyeloplasty for pelvi-ureteric junction obstruction of lower moiety in partial duplex system: A technical challenge

    Directory of Open Access Journals (Sweden)

    Girdhar S Bora

    2016-01-01

    Full Text Available Management of pelvi-ureteric junction obstruction (PUJO in a duplex system is technically challenging as dissection at the pelvis may jeopardize the vascularity of the normal moiety ureter. Anastomosing the pelvis to the one single ureter will have a risk of future development of stricture which then will risk both the moieties. Robotic assistance enables appropriate tissue dissection; minimal handling of normal ureter and precision in suturing, overcoming the potential challenges involved in the minimally invasive management of such complex cases. We report the feasibility and efficacy of robot-assisted laparoscopic pyeloplasty in such case.

    A rare case of large periureteral lipoma in a 66-year-old woman is reported. The tumor measuring 16×7×7cm in size was located from the upper portion of the right ureter to the renal pelvis. It is considered that the severe hydronephrosis and renal lithiasis occurred as a result of stenosis in the upper urinary tract due to compression by the tumor. Although the differential diagnosis was difficult radiologically, the tumor was easily diagnosed as lipoma by hi stop athological investigation.

    The present study reports the clinical data of two patients with renal pelvis carcinoma and one patient with renal carcinoma who developed port-site metastasis following retroperitoneal laparoscopic surgery. The current study aimed to identify the cause and prognosis of the occurrence of port-site metastasis subsequent to laparoscopic radical resection of renal pelvis carcinoma and nephron-sparing surgery. Post-operative pathology confirmed the presence of high-grade urothelial cell carcinoma in two patients and Fuhrman grade 3 renal clear cell carcinoma in one patient. Port-site metastasis was initially detected 1–7 months post-surgery. The two patients with renal pelvis carcinoma succumbed to the disease 2 and 4 months following the identification of the port-site metastasis, respectively, whereas the patient with renal carcinoma survived with no disease progression during the targeted therapy period. The occurrence of port-site metastasis may be attributed to systemic and local factors. Measures to reduce the development of this complication include strict compliance with the operating guidelines for tumor surgery, avoidance of air leakage at the port-site, complete removal of the specimen with an impermeable bag, irrigation of the laparoscopic instruments and incisional wound with povidone-iodine when necessary, and enhancement of the body's immunity. Close post-operative follow-up observation for signs of recurrence or metastasis is essential, and systemic chemotherapy may be required in patients with high-grade renal pelvis carcinoma and renal carcinoma in order to prolong life expectancy.

    The aim of this study was to present CT findings of occult ureteropelvic junction obstruction in patients with renal trauma and to describe the clinical signs and singular CT features that are characteristically observed with trauma and are relevant to management of these patients. We retrospectively reviewed 82 helical CT studies in patients with renal trauma referred to our institution. We found 13 cases of occult preexisting renal pathology, six of which were occult ureteropelvic junction obstructions. The clinical presentation, radiologic findings of trauma according to the Federle classification, and CT findings of obstructed ureteropelvic junction are presented. We found three category-I lesions (one in a horseshoe kidney), two of them treated with nephrostomy because of increased ureteropelvic junction obstruction due to pelvic clots; two category-II lesions (parenchymal and renal pelvis lacerations) that had presented only with microhematuria; and one category-IV lesion (pelvic laceration alone). Pelvic extension was demonstrated in all the cases with perirenal collections. The CT studies in all the cases with suspected ureteropelvic junction obstruction showed decreased parenchymal thickness and enhancement, and dilatation of the renal pelvis and calyx, with a normal ureter. Computed tomography can provide information to confidently diagnose underlying ureteropelvic junction obstruction in renal trauma, categorize the traumatic injury (at times clinically silent) and facilitate proper management according to the singularities observed, such us rupture of the renal pelvis alone (Federle category IV) and increasing ureteropelvic obstruction due to clots which can be decompressed by nephrostomy.

    Full Text Available A Retrocaval Ureter ( Circumcaval Ureter is a developmental anamoly of inferior vena cava (IVC. Unfortunately both term suggest that ureter is at fault whereas in reality it is the IVC. There are two types of retrocavalureter.ie. T he high loop and low loop. This abnormality occurs as a result of the right supracardinal system failing to develop normally. The right posterior C a rdinal ve in persists and therefore ends up passing in front of ureter. With one exception, the anamoly always occurs on right side as this is the site of normal IVC. Many patients are asymptomatic but depending on the degree of compression, patients may develop partial ureteral obstruction or recurrent urinary tract infection (UTI due to urinary stasis. Though congenital anamoly , patients do not present until 3rd to 4 t h decade of life resulting from hydronephrosis (HDN. Surgical correction of the ureteric anamoly anterior to IVC can be performed in these cases. This case describes a case of retrocaval ureter in a 27year old female with recurrent UTI and flank pain in which open surgical uretero - ureteric anastomosi s (uretero - ureterostomy was done with excision of retrocaval part of ureter.

    We describe a case of renal pelvi-ureteric fungus ball managed with placement of two nephrostomy tubes and amphotericin B irrigation through a nephrostomy tube with the other to free drain. A 46-year-old man with uncontrolled Type 2 diabetes mellitus was referred to the urology clinic for workup of recurrent urinary tract infection. Urine culture grew Candida albicans. The patient was started on oral fluconazole therapy. Cystoscopy and cystogram revealed a grade 3 left vesicoureteral reflux and right retrograde pyelogram revealed a filling defect in the right renal pelvis extending into the proximal ureter with severe hydroureteronephrosis. Two nephrostomy tubes were placed (mid-pole and lower pole) to ensure that the system was not obstructed. Amphotericin B (50 mg/1000 ml normal saline) irrigation was then instilled through the mid-pole nephrostomy tube at a rate of 30 ml/h with the lower pole nephrostomy tube to free drain. An antegrade nephrostogram was performed after 5 days of amphotericin B instillation, showing complete resolution of the fungus ball. The patient is awaiting definitive minimally invasive management of the distal ureteral narrowing. Renal and pelvi-ureteric fungus ball is a challenging clinical entity. It must be addressed promptly and efficiently to be successful. We describe a minimally invasive approach that was tolerated well and resulted in complete clearance of the fungus ball in a relatively short time frame.

    Full Text Available Ureter duplication is the most common congenital anomaly of the urinary system. Ureteral duplication varies from a bifid pelvis to completely separate ureters. The reported incidence varies from 0.8% in an autopsy series, to 40% in a pyelography review, and displays a wide spectrum of imaging findings . The unilateral form occurs about 6 times more commonly than the bilateral form, with the left and right sides being almost equally involved. A 37 year old male with no previous history for stone disease presented to the urology department with right sided colicky pain for three hours. Ultrasonography and Computurized Tomography (CT were performed. We demonstrated radiologic findings of distal ureter with partially double lumen. According to our knowledge, it has not been reported in the literature previously.

    Objective To investigate the pmgnostic value of EpCAM and E-Cadherin in urothelial carcinoma of rpnal pelvis. Methods Ep-CAM and E-Cadherin were analyzed by immunohistochemistry using monoclonal antiliodies in 50 cases of normal mucosa and 76 cases of urothelial carcinoma of renal pelvis. Results The positive rate of EpCAM in urothelial carcinoma of renal pelvis was 60.5% .which was significantly higher than in para-cancerous mucosa of 27.6%. The expression of EpCAM was significantly related with the differential clinical stage,pathological degree,distant metastasis and bladder tumor recurrence (all P< 0.05). The expression of E-Cadherin was significantly re-lated with the differential clinical stage,pathological degree and distant metastasis (all P < 0.05). There was negative correlation between the expression of EpCAM and E-Cadherin in urothelial carcinoma of renal pelvis ( r =-0.425,P < 0.01). Conclusion The expression EpCAM and E-Cadherin are highly related to occurrence,development,infiltration and metastasis of urothelial carcinoma of renal pelvis,and evaluation of the two proteins could be a very applicable guidance for the diagnosis of metastasis and invasion of urothelial carcinoma of renal pelvis.%目的 探讨EpCAM和E-Cadherin的表达与肾盂癌病理分级和临床分期的关系.方法 应用免疫组织化学SP法检测76例不同级别肾盂癌和50例癌旁正常组织中EpCAM和E-Cadherin的表达.结果 EpCAM在肾盂癌阳性表达率为60.5%(46/76),明显高于癌旁组织27.6%(21/76),差异具有统计学意义(P<0.05);EpCAM的表达与肾盂癌不同临床分期、病理分级、远处转移及继发膀胱肿瘤相关(P<0.05);EpCAM与E-Cadherin在肾盂癌中表达呈负相关(r=-0.425,P< 0.01).结论 EpCAM及E-Cadherin的表达变化与肾盂癌的发生发展、浸润转移有良好的相关性,同步检测二者在肾盂癌组织中的表达并综合分析两者之间的关系对评价肾盂癌的侵袭转移能力判断具有一定价值.

    Full Text Available Renal calculus is a solid or crystal aggregation formed in the kidneys from minerals in the u rine . Many calculi are formed and passed without causing symptoms. A kidney stone is a hard, crystalline mineral material formed within the kidney or urinary tract. Renal calculi affect all geographical, racial and groups with a worldwide prevalence of bet ween 2 and 20%. Majority of the patients are usually between the 20 - 55 years of age. The highest incidence of kidney stone is in 30 - 45 years of age group and the incidence declines after the age of 50 years of age. Stones that obstruct the ureter or renal pelvis cause excruciating, intermittent pain.

    Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

    To compare intravenous urography (IVU) and magnetic resonance urography (MRU) in the preoperative evaluation of pelvi-ureteric junction obstruction (PUJO) in children. A total of 35 children up to 10 years of age in whom unilateral or bilateral PUJO were suspected on ultrasonography were enrolled in this prospective study. All children underwent IVU and MRU, and the findings were compared. Of the 70 kidneys evaluated, 14 (20%) were not visualized on IVU because of nonexcretion of contrast, whereas all the 70 (100%) kidneys were visualized on MRU. On IVU, nephrogram was not visualized in 66 (94.2%) of the 70 kidneys, whereas MRU showed prompt and homogeneous nephrogram in 68 (97.1%) of the 70 kidneys. No evidence of PUJO was seen in 31 (44.2%) kidneys on both IVU and MRU. IVU showed PUJO in 26 (37.1%) kidneys, whereas MRU showed it in 38 (54.2%) kidneys. MRU detected two duplex systems that were missed on IVU. A focal renal lesion and two incidental extra renal abnormalities were detected on MRU, which were not visualized on IVU. MRU is better than IVU, especially in case of poorly functioning kidneys which are not visualized on IVU. MRU also provides anatomic details of the ureter and vessels with better evaluation of renal parenchyma. It also has an additional advantage of detecting incidental extra renal abnormalities, if present.

    To describe the radiological findings associated with ectopic ureterocele and ectopic ureter in pediatric patients. To assess the role of ultrasound (US), serial micturating cystourethrography (SM-CU) and intravenous urography (IVU) in the diagnosis of these two entities. The authors performed a retrospective study of 132 patients, 73 with ectopic ureterocele and 59 with ectopic ureter. The imaging studies used were US, SMCU, IVU and methods to determine renal function (diuretic renography and renal scintigraphy). The findings were confirmed during surgery in every case. The most common radiological findings in ectopic ureterocele were renal duplication (86,3%). vesicoureteral reflux (VUR) to the lower half of the kidney (46.6%), dilatation of the lower pole of the kidney (38.4%) and contralateral duplication (30.1%). In boys, the ectopic ureter entered via bladder neck and posterior urethra (73.7%) or into seminal vesicles (15.8%); in girls, it went to vagina (32.5%), bladder neck (30%) or urethra (22.5%). Renal duplication was associated in 64.4%, with VUR to the ectopic ureter in 21% while there was a single renal system in 35.6%, with VUR to the ectopic ureter in 57.1% and contralateral renal agenesis in 19%. Eighteen patients (13.6%) presented a single, dy plastic, nonfunctioning renal system (6 cases of ureterocele and 12 of ectopic ureter). Knowledge of the embryological development of ureteral duplication is essential for the understanding of these two entities and helps to differentiate between them, thus facilitating a sometimes complicated diagnosis. Ectopic ureters and ureteroceles accompanied by a single, dysplastic renal system are associated with a greater incidence of congenital anomalies and a higher rate of complications than the duplicate systems. A prenatal US examination enables early diagnosis. The anatomical information provided by US is, on occasion, more valuable than that resulting from IVU or SMCU, However, IVU is indispensable in girls

    The retrocaval ureter is a rare congenital entity, classically managed with open pyeloplasty techniques. The experience obtained with the laparoscopic approach of other more frequent causes of ureteropelvic junction (UPJ) obstruction has opened the method for the minimally invasive approach of the retrocaval ureter. In our paper, we describe a clinical case of a right retrocaval ureter managed successfully with laparoscopic dismembered pyeloplasty. The main standpoints of the procedure are described. Our results were similar to others published by other urologic centers, which demonstrates the safety and feasibility of the procedure for this condition. PMID:27635277

    In a 23-year-old man attacks of nephritic colic led to the discovery of an obstruction on the left lumbar ureter. Segmental resection of the ureter was performed, removing 10 mm of malformed, obstructed ureter. This was an incomplete duplication, the two ureteral segments lying side-by-side, each with its own musculature, for a distance of 7mm. Above and below the anomaly, the ureter was normal. This exceptional malformation is compared with other internal obstructions of the ureter.

    Lithium induces proliferation in the epithelium of renal collecting ducts. A recent small-scale cohort study reported a strong association between use of lithium and increased risk of renal neoplasia. We therefore conducted a large-scale pharmacoepidemiologic study of the association between long-term use of lithium and risk of upper urinary tract cancer, including renal cell cancer and cancers of the renal pelvis or ureter. We identified all histologically verified upper urinary tract cancer cases in Denmark between 2000 and 2012 from the Danish Cancer Registry. A total of 6477 cases were matched by age and sex to 259,080 cancer-free controls. Data on lithium use from 1995 to 2012 were obtained from the Danish Prescription Registry. We estimated the association between long-term use of lithium (≥5 years) and risk of upper urinary tract cancer using conditional logistic regression with adjustment for potential confounders. Long-term use of lithium was observed among 0.22% of cases and 0.17% of controls. This yielded an overall nonsignificant adjusted odds ratio (OR) of 1.3 (95% confidence interval [95% CI], 0.8-2.2) for upper urinary tract cancer associated with long-term use of lithium. Analyses stratified by stage and subtype of upper urinary tract cancer revealed slight but nonsignificant increases in the ORs for localized disease (OR, 1.6; 95% CI, 0.8-3.0) and for renal pelvis/ureter cancers (OR, 1.7; 95% CI, 0.5-5.4). In conclusion, in our nationwide case-control study, use of lithium was not associated with an increased risk of upper urinary tract cancer.

  15. Laparoendoscopic Single-site Repair of Retrocaval Ureter Without any Special Devices

    2013-01-01

    Full Text Available INTRODUCTION The retrocaval ureter is a rare congenital anomaly. The extrinsic compression may be responsible for obstruction and pain symptoms. The laparoscopic approach has been used with good results and less morbidity than the open surgery. Herein we describe a case of retrocaval ureter treated with LESS. To our knowledge, this represents the second such case reported in the literature, and the first without using any special devices, such as, single port or bended instruments. PRESENTATION Female, 23 years, complaining of right low back pain for a long time and recurrent urinary tract infection. Renal ultrasound demonstrated right-sided hydronephrosis and intravenous urography suggested the presence of retrocaval ureter. DTPA renal scintigraphy confirms delay in the elimination of contrast through the right kidney. A laparoendoscopic single-site repair was planned. The patient was placed in rightside-up modified flank position. A semicircular intra-umbilical incision was made and the conventional trocars (one 10 mm and two 5 mm were inserted through the same incision on different points of the aponeurosis. The colon was dissected medially and the proximal ureter lateral to the vena cava was identified and dissected. An extra corporeal repair with Vycril 2-0 was used to facilitate the ureteral dissection and the anastomosis. A segment of ureter was ressected due to the tortuosity. Two 4-0 Vycril sutures were used to perform a running anastomosis. An ureteral stent was placed after the posterior layer on an antegrade fashion. A suction drain was left through the umbilicus. RESULTS The total operative time was 145 min. The blood loss was minimal. The patient was discharged on the third postoperative day and resumed total activity about 10 days after surgery. The double J was removed within 4 weeks. DISCUSSION Albeit technically challenging, LESS repair for retrocaval ureter might represent a feasible new treatment option for this rare anatomic

    Background The delayed diagnosis of pelvi-ureteric junction (PUJ) disruption in children following blunt abdominal trauma can result in loss of function of the involved kidney. We examined the potential for kidney preservation and the limits of diagnostic delays. Methods A retrospective review of 17 cases of PUJ disruption at Beijing Children's Hospital from 1993 to 2009 was done with respect to diagnosis, treatment and follow-up. Results The interval from trauma to diagnosis of PUJ disruption was (52±52) days. If one case with nephrectomy was excluded, the interval from trauma to diagnosis was (40±20) days. The average time between injury and first treatment was (49±25) days. Pelvi-ureteric reanastomosis and caliceal ureterostomy were performed separately in 11 and 4patients, respectively. lleal replacement for ureter injuries was finally performed in one patient. Hydronephrosis of the injured kidney was reduced and the function improved in 15 out of 17 patients (88%). Only one patient received nephrectomy and the nephrectomy rate was 5.9%. Conclusion Differential renal function at the PUJ disruption side can be saved and the rate of nephrectomy reduced by appropriate surgery if the time to diagnosis and first treatment is limited to within two months.

    Full Text Available We present the case of a young man with Klinefelter syndrome, who was admitted to our clinic with renal colic. Shortly after admittance, spontaneous decrease in pain has occurred. Ultrasound and intravenous contrast computed tomography were performed, which showed the evidence of urine extravasation at the level of left renal pelvis and a 4 mm stone in the lower third of the left ureter. The management with a double-J ureteric stent for three weeks was successful. Then, the stent was removed and computed tomography confirmed the absence of urine extravasation. We also analyze the literature related to this case and discuss the main mechanisms of collecting system rupture.

    The widespread use of fetal ultrasonography results in a frequent antenatally observation of hydronephrosis, ureteropelvic junction obstruction (UPJO) accounting for the greatest fraction of congenital obstructive nephropathy. UPJO may be considered, in most cases, as a functional obstructive condition, depending on defective fetal smooth muscle/nerve development at this level, with lack of peristaltic wave propagation--aperistaltic segment--and, therefore, poor urine ejection from the renal pelvis into the ureter. The UPJO-related physiopathologic events are, at first, the compliant dilatation of renal pelvis that, acting as hydraulic buffer, protects the renal parenchyma from the rising intrapelvic pressure-related potential damages, and, subsequently, beyond such phase of dynamic balance, the tubular cell stretch-stress induced by increased intratubular pressure and following parenchymal inflammatory lesions: inflammatory infiltrates, fibroblast proliferation, activation of myofibroblasts, tubulo-interstitial fibrosis. Reactive oxygen species (ROS), nitric oxide (NO), several chemo- and cytokines, growth factors, prostaglandins and eicosanoids, angiotensin-II are the main pathogenetic mediators of the obstructive nephropathy. Apoptosis of tubular cells is the major cause of the tubular atrophy, together with epithelial-mesenchymal transdifferentiation. Some criticisms on tout court semantic renal pelvis dilatation-obstruction connection have been raised considering that the renal pelvis expansion isn't, in any case, linked to an ostructive condition, as it may be verified by diuretic (furosemide) renogram together with scintiscan-based evaluation of differential renal function. In this regard, rather than repetitive invasive nuclear procedures that expose the children to ionizing radiations, an intriguing noninvasive strategy, based on the evaluation of urinary biomarkers and urinary proteome, can define the UPJO-related possible progress of parenchymal lesions

    Full Text Available We had a 14 year old boy, who presented with recurrent attacks of right loin pain. Investigations revealed a retrocaval ureter. A transperitoneal three port laparoscopic approach was undertaken. The retrocaval portion of ureter was excised. A double J stent was placed laparoscopically and ureteroureterostomy was done with intracorporeal suturing. The patient was discharged after 72 hours and the stent was removed on the 15th day. Follow up showed regression of hydronephrosis. We recommend this approach compared to open surgery, as it offers several advantages compared to conventional open surgery like decreased postoperative pain, decreased hospital stay and a cosmetically more acceptable surgical scar.

    Full Text Available The case of a 45-year-old woman who was admitted to our university hospital for polymenorrhea, weight gain and pain in the left iliac region is reported. An abdominal ultrasound revealed a 9.5 × 5.2-cm, hypoechoic and inhomogeneous mass located on the left side of the pelvis and behind the ovary. The patient underwent surgery. The pelvic mass was firmly anchored to the small intestine, colon, sigma and uterine fundus. After removing the adhesions, double ureters, which had been incorporated in the mass, were observed on the left side. Resection of the unilateral double ureters was necessary in order to remove the entire mass, and thereafter, a left salpingoophorectomy was performed. A histological examination showed a malignant retroperitoneal mass. Termino-terminal ureteral anastomosis with two double-J stents was carried out. Total hysterectomy with preservation of the right adenexum and regional lymphadenectomy was performed. The purpose of this case report is to discuss the physical and psychological implications related to the combination of two rare entities: leiomyosarcoma and a double ureter located within the mass. A literature review on the clinical management and psychological aspects from a female cancer patient's perspective undergoing surgery with the aforementioned disorders will be discussed.

    To explore the diagnostic value of magnetic resonance urography (MRU) in ectopic ureters. Seventeen female children with ectopic ureter were examined by sonography, intravenous urography (IVU), computer tomography (CT), MRU and so on. The mean age of the female children was 4.5 years (7 months approximately 12 years). Seventeen patients were examined by sonography, including 3 dysplasia little kidneys, 1 kidney absence, 12 duplex kidneys with hydroureter, 1 normal.Seven patients were examined by IVV, including 3 hydronephrosis and 4 no image or not clear. Fourteen patients were examined by CT, including 3 dysplasia little kidneys, 11 duplex kidneys with hydronephrosis. Five were determined by cystoscope, including 2 ecto-pic urethral orifices which angiography could only display the expansion of ureter. All children were diagnosed by MRU and an accurate anatomical picture of the entire urinary tract was obtained. To accurately and noninvasively depict the urinary tract and the independence of renal function, MRU may be used for patients with ectopic ureter undiagnosed with sonography and IVU.

    Full Text Available Duplex system is a duplication of renal parenchyma, pelvis and collecting system. It could be complete, if ureters lead to bladder separately or incomplete, if they joint before coming out. This study aims duplex system management evaluation, defining indications of conservative or demolitive therapy, and results. Materials and methods. At the section of pediatric surgery of University of Siena we have observed 27 patients with duplex system from January 1980 to May 2011: 7 male (26% and 20 female (74%, 18 (67% with complete duplicity, 9 (33% with incomplete one. Patients were divided into 2 groups: the first one was composed by 12 children (44%, they had negative diagnostic exams for alterations of renal function and associated diseases and no symptoms;the second group had 15 children (56% whose diagnostic-therapeutic iter was based on associated malformations and symptoms of each case. We found: 5 RVU (33% with 1 Hutch diverticulum; 5 ureteroceles (33%; 3 ectopic ureters (20%; 4 megaureters (26%, 6 renal dysplasia and upper pole function <10% (40%. Results. Children belonging to second group were treated in different ways. 5 babies (33% with RVU were approached with submeatal infiltration; 1 baby (7% with ureterocele was treated with excision of the malformation and Cohen reimplatation; 2 ureteroceles (13% were incised by transurethral approach and RVU appeared, 1 of them was then treated with eminephroureterectomy; in 1 case of ureterocele (7%and 1 of ectopic ureter (7% no treatment was undertaken and 1 baby with ureterocele (7% needed eminephoureterectomy; 4 kidneys (26% with upper pole impaired function required em- inephroureterectomy. All second group patients, except 3, had a 2-16 years follow-up and they showed normal growth and no symptoms. First group children had negative exams and excellent clinic conditions. Conclusions. Our results suggest that management should be decided on patient’s age, clinic presentation and associated

    Renal masses account for 55% of cases presenting as palpable abdominal mass in children.[1] An eight year male presented with palpable abdominal mass and pain. The patient underwent renal dynamic scan, which raised possibility of left duplex kidney with non-functioning moiety, as the size of left kidney was smaller than seen on Ultrasonography (USG). Magnetic resonance (MR)urography confirmed the findings with patient undergoing left hemi-nephrectomy and is doing well. In case of discrepancy in size of kidney on USG and renal scan, duplex kidney should be considered as differential, other causes being, renal cyst, benign/malignant mass and renal calculi. Gross hydro-ureter presenting as palpable abdominal mass is very rare with few reported cases.[234].

    Magnetic resonance urography (MRU) is one of the most attractive imaging modalities in paediatric urology, providing largest diagnostic information in a single protocol. Therefore, the aim of our study was to assess the diagnostic value of MRU in children with urogenital anomalies (especially anomalies of the renal pelvis and ureter) and the renal function using different post-processing functional software. Ninety six children (7 days - 18 years old) were examined. In 54 patients of them, a static T(2) MRU was completed by excretory T(1) MRU after gadolinium administration and functional analysis has been performed using two functional analysis softwares "CHOP-fMRU" and "ImageJ" software. MRU showed suspicious renal and the whole urinary tract anomalies with excellent image quality in all children. In ureteropelvic obstruction, MRU was confirmatory to the other imaging techniques, but it was superior modality concerning the evaluation of end-ureteral anomalies. There was an excellent correlation between the MRU data and diagnosis, determined by surgery. The renal transit times, renal volumes and volumetric differential renal function were assessed separately by "CHOP-fMRU" and "ImageJ" with excellent agreement with 99(m)Tc-DTPA and among them. MRU overcomes a lot of limitations of conventional imaging modalities and has a potential to become a leading modality in paediatric uroradiology. Synthesis of both anatomical and functional criteria in MR urography enables to select the best candidates for surgical treatment. Even small kidney dysfunction can be detected by functional analysis software.

  12. Double obstruction of ureter: A diagnostic challenge

    Full Text Available Introduction: Isolated obstruction of the ureteropelvic junction and the vesico-ureteric junction are the two most common causes of hydronephrosis in a pediatric population. [1] They do not pose diagnostic difficulties when are present alone but when together can be difficult to diagnose. Here, we discuss the problems we faced when we encountered these two anomalies in the same ureter and the way in which we managed them. Aim: To assess the difficulties in diagnosis of pediatric patients who present with both ureteropelvic junction obstruction (UPJO and vesico-ureteric junction obstruction (VUJO in the ipsilateral ureter and their management protocol. Materials and Methods: This is a retrospective study. The study period is from 1 January 2004 to 31 December 2011. Out of 254 children who were diagnosed to have hydronephrosis due to UPJO in our institute, 5 patients (in the age range of 5 to 10 years had both UPJO and VUJO in the ipsilateral ureter. The problems we faced in diagnosing the two conditions are mentioned with a literature review. Results: Operative intervention was used in four out of five patients; none of the patients had an accurate diagnosis before surgery. All patients were suspected of having double obstruction during pyeloplasty when appropriate size double J stent could not be negotiated through the vesicoureteric junction into the bladder. Postoperative nephrostogram confirmed the diagnosis in all patients. Conclusion: Children with double obstruction of the ipsilateral ureter present as a diagnostic dilemma. Because of the rarity of this condition it can escape the eye of even an astute clinician. Early diagnosis can be made if this condition is kept in mind while treating any hydronephrosis due to UPJO or UVJO.

    Kaposi sarcoma after an organ transplant is rare and infrequently involves internal organs. There are 2 reported cases in the English literature of Kaposi sarcoma originating from the transplant ureter after kidney transplant. We report a case of Kaposi sarcoma that occurred in the native ureter of the liver transplant recipient. Initially, the patient refused any further investigation and management and 2 years subsequent, had to undergo a left radical nephroureterectomy owing to the loss of renal function and distending pain. He recovered very well and no recurrence was detected at 47 months' follow-up. To our knowledge, it is the first report in English. We review the literature on this topic and explore the therapeutic principles and histologic features of this sarcoma.

    Ectopic ureters are often very difficult to diagnose with conventional diagnostic modalities (physical examination, ultrasound, intravenous urography, cystography, urethro-cystoscopy, isotop examinations) in children. The authors report their experience with a relatively new method, the magnetic resonance urography (MRU) diagnosing ectopic ureters in childhood. MRU was used in 7 girls to detect an ectopic ureter in the last 3 years. On the basis of typical clinical signs, an ectopic ureter was suspected in all patients, but it could not be demonstrated by conventional diagnostic methods. Thus, MRU was done to confirm the suspected diagnosis. In all of the 7 patients, the examinations demonstrated ectopic ureters with the intraoperative findings further confirming the pre-operative diagnosis. In 2 patients, the intraoperative findings of the upper urinary tract anomalies were slightly different from the MRU report. The MRU is a reliable diagnostic method to diagnose ectopic ureters which are not easily detectable with conventional diagnostic modalities.

  15. Analysis of Urine Flow in Three Different Ureter Models

    Directory of Open Access Journals (Sweden)

    Kyung-Wuk Kim

    2017-01-01

    Full Text Available The ureter provides a way for urine to flow from the kidney to the bladder. Peristalsis in the ureter partially forces the urine flow, along with hydrostatic pressure. Ureteral diseases and a double J stent, which is commonly inserted in a ureteral stenosis or occlusion, disturb normal peristalsis. Ineffective or no peristalsis could make the contour of the ureter a tube, a funnel, or a combination of the two. In this study, we investigated urine flow in the abnormal situation. We made three different, curved tubular, funnel-shaped, and undulated ureter models that were based on human anatomy. A numerical analysis of the urine flow rate and pattern in the ureter was performed for a combination of the three different ureters, with and without a ureteral stenosis and with four different types of double J stents. The three ureters showed a difference in urine flow rate and pattern. Luminal flow rate was affected by ureter shape. The side holes of a double J stent played a different role in detour, which depended on ureter geometry.

    2015-01-01

    Full Text Available Background: Primary congenital bladder diverticulum (PCBD is related to a deficient detrusor layer allowing out-pouching of the bladder mucosa through the inadequate muscularis wall. We aimed to review our experience with symptomatic PCBD in order to correlate clinical findings with anatomical aspects and to present late outcome. Materials and Methods: We reviewed all patients operated in our institution since 2004. We evaluated the charts for complaints, radiological exams, method of treatment, complications and length of follow-up. Results: We treated 10 cases (11 renal units - [RU], predominantly males (9/10, mean age at surgery of 5.3 years. All patients had significant urological complaints presenting either with antenatal hydronephrosis (4 or febrile urinary tract infection (5 and urinary retention in one. The ureter was found implanted inside the diverticulum in 8/11 RU. An extravesical psoas-hitch ureteroneocystostomy and diverticulum resection was performed in 10/11 cases, whereas 1 case was treated intravesically based on surgeon′s preference without performing cystoscopy. Mean follow-up was 34.1 months (1-120 without complications. Conclusions: PCBD is an uncommon diagnosis and has a high probability of drainage inside the diverticulum (72.7%. We recommend the extravesical approach associated with diverticulectomy and ureteroneocystostomy as the preferred technique to treat this abnormality.

  3. Ureter smooth muscle cell orientation in rat is predominantly longitudinal.

    Directory of Open Access Journals (Sweden)

    Bart Spronck

    Full Text Available In ureter peristalsis, the orientation of the contracting smooth muscle cells is essential, yet current descriptions of orientation and composition of the smooth muscle layer in human as well as in rat ureter are inconsistent. The present study aims to improve quantification of smooth muscle orientation in rat ureters as a basis for mechanistic understanding of peristalsis. A crucial step in our approach is to use two-photon laser scanning microscopy and image analysis providing objective, quantitative data on smooth muscle cell orientation in intact ureters, avoiding the usual sectioning artifacts. In 36 rat ureter segments, originating from a proximal, middle or distal site and from a left or right ureter, we found close to the adventitia a well-defined longitudinal smooth muscle orientation. Towards the lamina propria, the orientation gradually became slightly more disperse, yet the main orientation remained longitudinal. We conclude that smooth muscle cell orientation in rat ureter is predominantly longitudinal, though the orientation gradually becomes more disperse towards the proprial side. These findings do not support identification of separate layers. The observed longitudinal orientation suggests that smooth muscle contraction would rather cause local shortening of the ureter, than cause luminal constriction. However, the net-like connective tissue of the ureter wall may translate local longitudinal shortening into co-local luminal constriction, facilitating peristalsis. Our quantitative, minimally invasive approach is a crucial step towards more mechanistic insight into ureter peristalsis, and may also be used to study smooth muscle cell orientation in other tube-like structures like gut and blood vessels.

    2017-05-01

    No bone in the human postcranial skeleton differs more dramatically from its match in an ape skeleton than the pelvis. Humans have evolved a specialized pelvis, well-adapted for the rigors of bipedal locomotion. Precisely how this happened has been the subject of great interest and contention in the paleoanthropological literature. In part, this is because of the fragility of the pelvis and its resulting rarity in the human fossil record. However, new discoveries from Miocene hominoids and Plio-Pleistocene hominins have reenergized debates about human pelvic evolution and shed new light on the competing roles of bipedal locomotion and obstetrics in shaping pelvic anatomy. In this issue, 13 papers address the evolution of the human pelvis. Here, we summarize these new contributions to our understanding of pelvic evolution, and share our own thoughts on the progress the field has made, and the questions that still remain.

  13. Fstl1 antagonizes BMP signaling and regulates ureter development.

    Directory of Open Access Journals (Sweden)

    Jingyue Xu

    Full Text Available Bone morphogenetic protein (BMP signaling pathway plays important roles in urinary tract development although the detailed regulation of its activity in this process remains unclear. Here we report that follistatin-like 1 (Fstl1, encoding a secreted extracellular glycoprotein, is expressed in developing ureter and antagonizes BMP signaling activity. Mouse embryos carrying disrupted Fstl1 gene displayed prominent hydroureter arising from proximal segment and ureterovesical junction defects. These defects were associated with significant reduction in ureteric epithelial cell proliferation at E15.5 and E16.5 as well as absence of subepithelial ureteral mesenchymal cells in the urinary tract at E16.5 and E18.5. At the molecular level, increased BMP signaling was found in Fstl1 deficient ureters, indicated by elevated pSmad1/5/8 activity. In vitro study also indicated that Fstl1 can directly bind to ALK6 which is specifically expressed in ureteric epithelial cells in developing ureter. Furthermore, Sonic hedgehog (SHH signaling, which is crucial for differentiation of ureteral subepithelial cell proliferation, was also impaired in Fstl1(-/- ureter. Altogether, our data suggest that Fstl1 is essential in maintaining normal ureter development by antagonizing BMP signaling.

    PurposeThis study was designed to demonstrate the accordion sign within the transplant ureter and evaluate its ramifications during balloon dilation of strictures.MethodsA retrospective electronic chart and imaging review included demographic characteristics, procedure reports, and complications of 28 renal transplant patients having ureteral strictures treated with percutaneous balloon dilation reported in our transplant nephrology database during an 8-year period. The accordion sign was deemed present or absent on the basis of an imaging review and was defined as present when a tortuous ureter became kinked and irregular when foreshortened after placement of a wire or a catheter. Procedure-related urine leaks were categorized as occurring at the stricture if within 2 cm; otherwise, they were considered away from the stricture.ResultsThe accordion sign was associated with a significantly greater occurrence of leaks away from the stricture (P = 0.001) but not at the stricture (P = 0.34).ConclusionsThe accordion sign is an important consideration when performing balloon dilation procedures on transplant ureteral strictures, given the increased risk of leak away from the stricture. Its presence should prompt additional care during wire and catheter manipulations.

    Background Magnetic resonance urography (MRU) is one of the most attractive imaging modalities in paediatric urology, providing largest diagnostic information in a single protocol. Therefore, the aim of our study was to assess the diagnostic value of MRU in children with urogenital anomalies (especially anomalies of the renal pelvis and ureter) and the renal function using different post-processing functional software. Patients and methods Ninety six children (7 days – 18 years old) were examined. In 54 patients of them, a static T2 MRU was completed by excretory T1 MRU after gadolinium administration and functional analysis has been performed using two functional analysis softwares “CHOP-fMRU” and “ImageJ” software. Results MRU showed suspicious renal and the whole urinary tract anomalies with excellent image quality in all children. In ureteropelvic obstruction, MRU was confirmatory to the other imaging techniques, but it was superior modality concerning the evaluation of end-ureteral anomalies. There was an excellent correlation between the MRU data and diagnosis, determined by surgery. The renal transit times, renal volumes and volumetric differential renal function were assessed separately by “CHOP-fMRU” and “ImageJ” with excellent agreement with 99mTc-DTPA and among them. Conclusions MRU overcomes a lot of limitations of conventional imaging modalities and has a potential to become a leading modality in paediatric uroradiology. Synthesis of both anatomical and functional criteria in MR urography enables to select the best candidates for surgical treatment. Even small kidney dysfunction can be detected by functional analysis software. PMID:22933962

    At present, the renal pelvis cancer incidence in China to rise, and its cause is not clear, most of the patients at the age of 41~63 years old in the elderly population, and in males. The most common clinical symptoms of renal pelvic carcinoma is the whole process of indirect visible to the naked eye hematuria, and with low back pain, decreased appetite, dif iculty in urination and other symptoms. Research and analysis to continuously in recent years, the incidence of carcinoma of renal pelvis and the environment, food chemical factors have correlation, some research shows that smoking is more concrete, and also has a direct relationship. At the same time of renal pelvis carcinoma is a common evil tumor in urinary system, at the same time as the disease position is special, in the ureter, bladder and urethra, confirmed the need for detailed examination, by examining the early diagnosis of comprehensive system, prevent to delay the disease, which is crucial for carcinoma of renal pelvis examination.%目前肾盂癌在我国的发病率以呈上升趋势,其发生的原因还不清楚,多数患者年龄在41~63岁的中老年人群,并且以男性居多。临床肾盂癌最常见症状是间接性肉眼可见血尿全过程,并且伴随腰痛、食欲下降、排尿困难等症状。通过近年来不断的研究和分析,提出肾盂癌的发病与环境、饮食化学物质等因素都有关联,有些研究显示更具体,表明与吸烟也有直接的关系。同时肾盂癌作为泌尿系统中常见恶的肿瘤,同时由于病症位置比较特殊,在输尿管、膀胱乃至尿道地,确诊需要进行详细的检查,通过全面系统的检查早期确诊,防止耽误病情,由此对于肾盂癌的检查至关重要。

    loss of significant lengths of ureter when substitution with bowel or bladder fails is a disaster in urology. This study is conducted to evaluate the results of subcutaneous nephron-vesical bypass (SNVB) in ureteral damage of different etiologies. Seventeen SNVB were employed in patients with ureteral injuries. We employed a device consisted of an internal silicone tube covered by a coiled PTFE tube to replace the ureter. This is called artificial ureter (AU). Proximal end of the AU was introduced in the kidney percutaneously, the tube was passed through a subcutaneous tunnel, while the distal end was inserted in the bladder through a small suprapubic incision. Follow-up ranged from six months to ten years. We removed the prosthetic ureter in one patient due to gross hematuria two months after insertion. One of the patients was reoperated two days after the procedure because of urinary leakage. In all other patients, the procedure was safe and effective. Subcutaneous nephron-vesical bypass is a safe and appealing alternative to a nephrostomy tube. This is a permanent device with no need for exchange. The technique can be applied in ureteral injuries due to various causes.

    Full Text Available Purpose The objective of this paper is to analyze the structure of the ureter in normal and anencephalic human fetuses. Materials and Methods We studied 16 ureters from 8 human fetuses without congenital anomalies aged 16 to 27 weeks post-conception (WPC and 14 ureters from 7 anencephalic fetuses aged 19 to 33 WPC. The ureters were dissected and embedded in paraffin, from which 5 µm thick sections were obtained and stained with Masson trichrome, to quantify smooth muscle cells (SMC and to determine the ureteral lumen area, thickness and ureteral diameter. The samples were also stained with Weigert Resorcin Fucsin (to study elastic fibers and Picro-Sirius Red with polarization and immunohistochemistry analysis of the collagen type III fibers to study collagen. Stereological analysis of collagen, elastic system fibers and SMC were performed on the sections. Data were expressed as volumetric density (Vv-%. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done using the Image Pro and Image J programs. For biochemical analysis, samples were fixed in acetone, and collagen concentrations were expressed as micrograms of hydroxyproline per mg of dry tissue. Means were statistically compared using the unpaired t-test (p < 0.05. Results The ureteral epithelium was well preserved in the anencephalic and control groups. We did not observe differences in the transitional epithelium in the anencephalic and control groups. There was no difference in elastic fibers and total collagen distribution in normal and anencephalic fetuses. SMC concentration did not differ significantly (p = 0.1215 in the anencephalic and control group. The ureteral lumen area (p = 0.0047, diameter (p = 0.0024 and thickness (p = 0.0144 were significantly smaller in anencephalic fetuses. Conclusions Fetuses with anencephaly showed smaller diameter, area and thickness. These differences could indicate that anencephalic fetal

    A 58-year-old Japanese female was admitted to our hospital for treatment of ovarian cancer. She had no urinary tract symptoms at the time of presentation. Preoperative CT (Computed Tomography) was performed for surgical planning, and it revealed two left-sided ureters including a short ureter with a blind, cystic ending and a short ureter joined to the main ureter before entering into the bladder. On CT urography, these radiological findings were compatible with a blind-ending bifid ureter. Preoperatively, a double J stent was inserted into the normal left ureter, and then the blind-ending bifid ureter was resected before an ovarian cancer operation.

    Urolithiasis is an ancient disease with global distribution. It refers to stones originating anywhere in the urinary system. Urinary calculi or stones are the most common cause of acute urinary system obstruction. The study was aimed with finding out the common site of urinary calculus in kidney ureter bladder (KUB) region. This was a prospective cross-sectional study conducted from June 2012 to September 2012 at Tribhuvan University, Teaching Hospital, Maharajgunj. A total 240 urolitiasis patients were enrolled for plain KUB examination. Site of urinary calculus was identified by observing KUB film of the subjects under the supervision of radiologist. The data were analyzed prospectively with outcome measures of gender & stone location. Out of 240 patients, 138 were male and 102 were female with male to female ratio of 1.35:1. The age ranged from 9 to 83 years. Out of total 240 patients, 71.9% (187) patients belonged to productive age group (20-60 years). Total number of urinary calculi was 345 in which 208 were found in male patients and 137 were found in female patients. Of total 345 calculi, 237 were renal stones, 47 were ureteric stones, 22 of the stones were found in pelviureteric junction (PUJ), 33 of stones were found in vesicoureteric junction (VUJ), and 6 were in bladder. In conclusion, urinary stone disease is a major public health problem in a developing country like Nepal with male and productive age group predominance. Kidney stones are most common. Distal ureter is the most common site of ureteric stone.

    Full Text Available CONTEXT: The association of primary carcinoma of the ureter and lithiasis is extremely rare. We report a rare case of a primary carcinoma of the ureter with corariform calculus. CASE REPORT: 60-year-old phaeodermal female, reported a history of right-side nephritic colic, hyperthermia and pyuria during the past 20 years and had received treatment for urinary infections a number of times. The first clinical presentation was related to lithiasis and the tumor had not been shown up by excretory urography, cystoscopy or ultrasonography. Two months after the calculus had been eliminated, the patient began to have serious symptoms and a grade III transitional cell carcinoma of the ureter was discovered. Total nephroureterectomy and M.V.A.C. (Metotrexate + Vinblastina + Doxo Rubicina + Cisplatina chemotherapy were tried unsuccessfully. In this report we emphasize the diagnostic difficulty caused by the concomitant presence of the two pathologies. In our opinion, the rapid evolution in this case is directly related to the high grade of the tumor.

    Full Text Available Objective: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. Material and methods: Here we report our experience in two cadaveric transplant patients with urolithiasis. The first case was a patient of 68 years with a 20 mm stone located in the transplanted kidney pelvis and another smaller in a lower calyx. The second case was a patient of 65 years with a 15 mm stone in the distal part of the transplanted ureter. In both cases the patients were asymptomatic, but they had a reduction in urine output associated with worsening of the transplanted kidney function. The diagnosis was performed in both cases with ultrasound study, showing a severe hydronephrosis and it was confirmed by computed tomography scan. In both cases, we performed a Percutaneous Nephrolithotomy (PCNL. Access was made after targeting the stone, through a lower pole puncture under ultrasound guidance. The first case was treated with pneumatic and laser energy, breaking stones through a nephroscope. In the second case we performed a laser lithotripsy of the ureteral stone, using a flexible videoureteroscope. At the end of both procedures a Double-J stent and a 14 Fr Malecot nephrostomy were positioned, that were removed at 6 weeks and 10 days, respectively. Results: Both patients achieved a resolution of the worsening of renal function, recovering the spontaneous diuresis. The surgical procedure using ultrasound guidance was safe and allowed quick access to the renal pelvis. Both patients experienced no bleeding or infection during hospitalization. Conclusions

    Full Text Available Objective To investigate the protective effects of sirolimus on unilateral ureteral obstruction (UUO induced renal fibrosis by blockage of mTOR and its mechanism. Methods Forty-two female rats were randomized to 3 groups: UUO group, sirolimus group (Sir group, and control group. UUO rats underwent unilateral ureteral ligation to reproduce renal fibrosis model. Sir group received sirolimus 2mg/kg wt per day (0.4ml, intragastric administration from one day before the UUO procedure to the end of study. The control group underwent surgery but without ureteral ligation. Obstructed kidneys were harvested on 7th and 14th day, and histological examination was performed for observing and comparing the degree of renal and renal tubule expansion. The concentrations of sodium, potassium and calcium ion in the urine obtained from the pelvis of the kidneys with ligated ureters were determined. At the same time, the expression of proliferating cell nuclear antigen (PCNA and apoptosis were observed with immunohistochemical method and TUNEL respectively. MicroRNAs quantities (mir-29c, mir-143, and mir-155 were assayed by quantitative PCR. Results At abovementioned two time-points, swollen kidneys and expanded renal tubules were observed in UUO and Sir groups as compared to control group, however, kidney in Sir group showed significantly less swelling and than that in UUO group (P < 0.01. Histological observation found tubular injury, cellular infiltration, and fibrosis were more marked in UUO group as compared to Sir group. Na+, K+ and Ca2+ of retention urine were significantly lower in Sir group than in UUO group (P < 0.05. PCNA-positive cell ratio and apoptosis ratio were higher in UUO group than in Sir and control groups (P < 0.01. No significant difference in expression of miR-155 or miR-143 was found between 3 groups, however, miR-29c expression in UUO group was down-regulated and significantly lower than that in control or Sir group (P < 0

    2013-09-01

    Full Text Available The paper presents the principles of performing proper ultrasound examinations of the urinary tract. The following are discussed: preparation of patients, type of optimal apparatus, technique of examination and conditions which its description should fulfill. Urinary track examination in adults and in children constitutes an integral part of each abdominal examination. Such examinations should be performed with fasting patients or several hours after the last meal, with filled urinary bladder. Apparatus: Ultrasound examinations in children and infants are performed using transducers with the frequency of 5.0–9.0 MHz and in adults – with the frequency of 2.0–6.0 MHz. Doppler options are desirable since they improve diagnostic capacity of sonography in terms of differentiation between renal focal lesions. Scanning technique: Renal examinations are performed with the patients in the supine position. The right kidney is examined in the right hypochondriac region using the liver as the ultrasound “window.” The left kidney is examined in the left hypochondriac region, preferably in the posterior axillary line. Ultrasound examinations of the upper segment of the ureters are performed after renal examination when the pelvicalyceal system is dilated. A condition necessary for a proper examination of the perivesical portion of the ureter is full urinary bladder. The scans of the urinary bladder are performed in transverse, longitudinal and oblique planes when the bladder is filled. Description of the examination: The description should include patient’s personal details, details of the referring unit, of the unit in which the examination is performed, examining physician’s details, type of ultrasound apparatus and transducers as well as the description proper.

    Full Text Available In renal transplantation surgery, double J stents (DJS are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmantation, encrustation and rarely sepsis are among the late complications of DJS. In this report we describe a renal transplantation case whose DJS stent was forgotten because the patient did not attend the regular follow-up and noticed 5 years after surgery.

    Conventional imaging modalities are limited in the assessment of complex lower urinary tract anomalies including ectopic insertion of ureters. MR urography can be useful in these situations. To share our experience with MR urography in assessing lower urinary tract anomalies and to determine its accuracy in depicting ectopic ureters. We conducted a retrospective review of all MR urography examinations done between November 2007 and March 2013 to note the presence or absence of duplex kidneys and insertion of ureters. We reviewed patient charts, surgical findings and results of other investigations including cystoscopy with retrograde ureterogram in order to establish presence or absence of ectopic ureter. This served as a reference standard against which we compared MR urography results. Of 22 MR urography examinations (3 boys, 19 girls; age range 3-16 years, mean 9.2 years) performed during the study period, 19 were performed to rule out ectopic ureters, two to assess complex anatomy and one to rule out crossing vessel in ureteropelvic junction obstruction. MR urography showed ectopic ureter in 9/19 children; one proved to be a false-positive. MR urography correctly showed normal insertion in 7/19 children. In the remaining 3/19 children distal ureter could not be seen, hence insertion was indeterminate on MR urography. One of these children had an ectopic ureter on cystoscopy and surgery. Statistical analysis showed MR urography's sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) to be 88.8-100%, 70-90%, 75-88.8% and 90-100% for the detection of ectopic ureter. MR urography is highly accurate in the assessment of ectopic ureters. In incontinent girls, MR urography should be the method of choice for depicting or ruling out ectopic ureter. (orig.)

    Full Text Available Introduction Ureteroscopy has improved from the first use of ureteroscope in the 1970's. Although the success rate increased in the last years, (1 new treatment techniques are being developed for impacted and large proximal ureter stones (2. Pneumatic lithotripsy has high efficiency with low complication rates (2. However, in case of steinstrasse and large (> 1 cm ureter stones, fragmented small stones may obstruct insertion of a ureteroscope after initial lithotripsy. In order to triumph over this issue, multiple ureteroscopic passages and manipulations needed for extraction of these small stones by forceps or basket catheters. The overall incidence of stricture was found upto 14.2% when the fragments were removed with a grasping forceps or a basket (3. We present our technique to disperse small fragmented stones in order to contact non-fragmented rest stone. Materials and Methods Ureteral lithotripsy was performed with an 8-9.8F semirigid ureteroscope using a pneumatic lithotripter (Swiss LithoClast, EMS, Nyon, Switzerland. The stone was fragmented into small pieces as small as 2-3 mm. by pneumatic lithotripter. Eventually, these fragmented stones interfered with vision and the lithotripter to get in touch with the rest stone. After fragmenting distal part of the large stone, the ureteroscope was pulled back out of ureter. While pulling back, the operating channel was closed and irrigation fluid was flowing in order not to decrease pressure behind the stones. Simultaneously, a person tilted the operating table to about 30° in reverse Trendelenburg position. When the ureteroscope was out of ureteral orifice, the operating channel was opened and irrigation fluid was stopped. This maneuver aided decreasing pressure in the bladder more rapidly in addition to feeding tube. Stone dust and antegrade fluid flow were easily seen out of the ureteral orifice. Ureteroscope was re-inserted after 30-60 seconds. While reaching the rest of the stone, small

    Full Text Available We report the first known case of anuric renal failure after same-session bilateral atraumatic flexible ureteroscopy for renal calculi. Although, there is no consensus about stenting patients who undergo same-session bilateral ureteroscopy due to the lack of prospective randomized studies; strong consideration should be given to stenting the ureter at least one side to avoid this complication.

    1975-06-01

    Fourty-one patients with primary invasive carcinomas of the ureter were seen at Memorial Hospital from 1947 to 1972. Overall survuval patterns were similiar in 19 patients with and 22 patients without prior or concomitant urothelial cancers elsewhere in the urinary tract, with 5-year survival rates, as estimated by the product-limit methos, of41% for both groups. Prognosis was determined primarily by anatomical stage of ureteral cancer. In 11 Stage A (submucosal) patients, 7 Stage B (muscular), 12 Stage C (periureteric fat), and 9Stage D (extraureteral), the similarly estimated 5-year survival rates were 91%, 43%, 23%, and nil, respectively. None of Stage A cases had metastases for periods ranging from 5 to 11 years after surgery alone. Seventy-eight percent of patients with more advanced stages died within 3 years of treatment, withmetastases mainly in pelvic and para-aortic lymph nodes.

  11. Circumcaval Ureter with Vesico Ureteral Reflux: The First Association in Literature

    Directory of Open Access Journals (Sweden)

    Full Text Available A circumcaval ureter is a rare congenital anomaly in which the ureter passes behind, and is compressed by, the inferior vena cava. Its etiology is assumed to be abnormal embryologic development of the inferior vena cava as a result of atrophy failure of the right subcardinal vein in the lumbar portion. A circumcaval ureter is also termed a retrocaval ureter. The right supracardinal system fails to develop, whereas the right posterior cardinal vein persists. With one reported exception, the anomaly always occurs on the right side. Patients with this anomaly may develop partial right ureteral obstruction or recurrent urinary tract infections. Therapeutic options include surgical relocation of the ureter anterior to the cava. A 14-year-old female patient came with complaints of fever, intermittent colic and dysuria 4 years ago. A right ureteric fourth-grade VUR and circumcaval ureter were established. An anomaly in which both of these are together could not be found in literature. If after the VUR treatment he has progressive abdomen pain and advancing hydronephrosis, a circumcaval ureter as an additive anomaly must not be forgotten. For that reason, in a patient having a urinary system anomaly, a likely extra anomaly should be searched. [Arch Clin Exp Surg 2012; 1(3.000: 191-194

    Full Text Available Villous adenoma is a rare primary tumor of the urinary system, especially the bladder and kidneys. This study presents two cases of right pelvis villous adenoma, including that of a 61-year-old patient who had experienced hematuria for more than 1 year and was diagnosed with bladder and ureteral stones via B-ultrasound examination, and the other one involving a 65-year-old patient who was hospitalized for 6 days due to a right upper quadrant mass and diagnosed with right renal pelvis stones and hydrops via B-ultrasound examination. Both patients underwent nephrectomy, and their histological analysis demonstrated papillary projections covered by columnar cells and goblet cells. The first patient had a large amount of renal pelvis mucus accumulation with obvious microscopic intestinal metaplasia and mild-moderate nuclear atypia. Immunohistochemical studies revealed positive carcinoembryonic antigen and the caudal type homeobox 2 staining with varying degrees of cytokeratin (CK-7 and CK20 expression in both patients. Recurrences or metastasis was not observed during the follow-up period of 3-4 years.

The diagnosis is often missed at intravenous urography (IVU and US because the ipsilateral ureter and kidney are grossly normal. In this case the diagnosis was established with ultrasound (US and mainly with multidetector computerized tomography (MDCT imaging using multiplanar reformats and 3-D reconstructions which were unique to this case. MDCT scans not only revealed the exact diagnosis and anatomic relationships but also ruled out other pathologies included in the differential diagnosis as well, such as ureter and bladder diverticula.

    To describe Magnetic Resonance Urography (MRU) appearances of the circumcaval ureter, a rare congenital cause of hydronephrosis. Seven cases of circumcaval ureter, suspected on intravenous urography (IVU), underwent subsequent static MRU using heavily T2-weighted sequences. The various appearances of circumcaval ureter on IVU and MRU were studied and compared. The circumcaval portion of the ureter was especially well seen on axial MRU sections, though this portion was routinely not visualized on IVU. In one case with a ureteric calculus, MRU also depicted a circumcaval course of the ureter, thus providing a complete diagnosis. In yet another case, where a circumcaval ureter was suspected on IVU, MRU proved the actual cause of ureteric obstruction to be a crossing vessel. Static MRU using heavily T2-weighted coronal and axial sequences can make or exclude the diagnosis of circumcaval ureter unequivocally.

    Full Text Available The primitive neuroectodermal tumor (PNET belongs to a group of highly malignant tumors and is composed of small round cells of a neuroectodermal origin. Categorized in the same tumor family as Ewing sarcoma, the PNET is most likely to occur in bones and soft tissues. However, a small number of PNET cases arising in the pelvis have been reported as well. We present three cases of pelvic PNET: two cases in the ovary and one case in the broad ligament. The PNET often exhibits aggressive clinical behavior with worse outcomes than other small round cell tumors. The significant prognostic factors of the PNET include site of tumor, volume of neoplasm, and presence of metastasis. The treatment protocol is multimodal and includes local surgical treatment followed by chemotherapy. We herein describe three PNET cases as a rare entity in the pelvis. Pelvic PNETs should be included in the differential diagnosis of pelvic masses.

    To determine trends in incidentally detected age- and gender-associated chondrocalcinosis on pelvic CT. Twenty patients of each gender at the center of each decade of life who underwent a CT scan of the pelvis performed 2009-2013 were identified and selected for a total of 400 pelvic CTs. Images were reviewed independently by two radiologists for the presence or absence of chondrocalcinosis within the pelvis. Patients with hip or low back pain, known CPPD arthropathy or any known predisposing condition, prior hip arthroplasty, or articular fracture were excluded. Logistic regression was used to predict the presence/absence of chondrocalcinosis as a function of patient age and gender. The presence/absence of chondrocalcinosis was found to be associated with patient age (p = 0.016) but not patient gender (p = 0.929). In the pelvis, chondrocalcinosis was most frequently identified at the pubic symphysis. Incidental chondrocalcinosis was not identified in any patients under 50 years of age. Chondrocalcinosis increased in frequency from 12.5 at 55 years of age to 27.5 % of patients 95 years of age. Chondrocalcinosis is common and more prevalent in late adulthood, occurs without a gender predilection, and is infrequently identified in patients younger than 50 years of age. (orig.)

    Purpose: To investigate the meaning of ureter dilatation during ultrasonography (US) in infants for evaluating vesicoureteral reflux (VUR). Materials and methods: We retrospectively reviewed abdominal US images of infants who were diagnosed with urinary tract infection (UTI group) or only hydronephrosis without UTI (control group). Hydronephrosis (graded 0–4) and ureter dilatation (present or absent) were evaluated on each side with US. Voiding cystourethrography (VCUG) within 3 months time interval with US was also reviewed and VUR was graded (0–5) on each side. Hydronephrosis, ureter dilatation, and VUR were then compared between the two groups. Results: Four hundred and three infants (142 in the UTI group and 261 in the control group) were included and VCUG was performed in 129 infants (68 in UTI and 61 in control groups). VUR grades were not different between the two groups (p = 0.252). Hydronephrosis grade was not related to VUR in either group (p > 0.05). However, ureter dilatation had a significant relationship with VUR in the UTI group (p = 0.015), even among patients with a high-grade VUR (p = 0.005). Whereas, ureter dilatation was not associated with VUR in the control group (p = 0.744). The relationship between ureter dilatation and VUR was different between the two groups for both all grades (p = 0.014) and high-grade (p = 0.004) VUR. Ureter dilatation had 66.7% sensitivity, 80.3% specificity, and 79.4% accuracy for evaluating high-grade VUR in the UTI group. Conclusion: Ureter dilatation on US can be a helpful finding for detecting VUR in infants with UTI, but not infants without UTI.

    With the greater frequency of renal transplant surgery, more female pts are becoming pregnant and carrying to term. In the renal allograft blood vessels and ureter may be compressed resulting in impaired renal function and/or, hypertension. Toxemia of pregnancy is seen more frequently than normal. Radionuclide renal scan monitoring may be of significant value in this high risk obstetrical pt. After being maintained during the pregnancy, renal function may also deteriorate in the post partum period. 5 pregnant renal transplant pts who delivered live babies had renal studies with Tc-99m DTPA to assess allograft perfusion and function. No transplanted kidney was lost during or after pregnancy as a result of pregnancy. No congenital anomalies were associated with transplant management. 7 studies were performed on these 5 pts. The 7 scans all showed the uterus/placenta. The bladder was always distorted. The transplanted kidney was rotated to a more vertical position in 3 pts. The radiation dose to the fetus is calculated at 0.024 rad/mCi administered. This study demonstrates the anatomic and physiologic alterations expected in the transplanted kidney during pregnancy when evaluated by renal scan and that the radiation burden may be acceptable in management of these pts.

    Discovery of a pelvis attributed to the Late Jurassic armor-plated dinosaur Gargoyleosaurus sheds new light on the origin of the peculiar non-vertical, broad, flaring pelvis of ankylosaurs. It further substantiates separation of the two ankylosaurs from the Morrison Formation of the western United States, Gargoyleosaurus and Mymoorapelta. Although horizontally oriented and lacking the medial curve of the preacetabular process seen in Mymoorapelta, the new ilium shows little of the lateral flaring seen in the pelvis of Cretaceous ankylosaurs. Comparison with the basal thyreophoran Scelidosaurus demonstrates that the ilium in ankylosaurs did not develop entirely by lateral rotation as is commonly believed. Rather, the preacetabular process rotated medially and ventrally and the postacetabular process rotated in opposition, i.e., lateral and ventrally. Thus, the dorsal surfaces of the preacetabular and postacetabular processes are not homologous. In contrast, a series of juvenile Stegosaurus ilia show that the postacetabular process rotated dorsally ontogenetically. Thus, the pelvis of the two major types of Thyreophora most likely developed independently. Examination of other ornithischians show that a non-vertical ilium had developed independently in several different lineages, including ceratopsids, pachycephalosaurs, and iguanodonts. Therefore, a separate origin for the non-vertical ilium in stegosaurs and ankylosaurs does have precedent.

    of clinical complications after electro-thermal injury to the ureter by bipolar electrocoagulation. Methods Thirty-six Japanese long-eared rabbits (1.9-2.4 kg, 6-8 months old) were randomly divided into two groups for phase Ⅰ and Ⅱ experiments (12 and 24 animals respectively). In phase Ⅰ experiment, totally 60 pieces of smooth muscles were collected from the 24 ureters of the 12 rabbits. The 60 pieces of ureteral smooth muscles were then divided into control, and 1- and 3-second electrocoagulation (bipolar electrocoagulation at 40 W) groups with 20 in each. The extent and frequency of smooth muscles contraction in the 1- and 3-second electrocoagulation groups, as well as histopathological changes of the injured segments were determined. In phase Ⅱ experiment, the rest 24 rabbits were randomly divided into 1- and 3-second electrocoagulation groups with 12 in each; electrocoagulation was made at the ureter at one side, 8 cm away from the renal pelvis. We observed the complications occurred to the ureter during two weeks after the operation, and then killed the rabbits to collect the injured ureter to determine its histopathological changes. Results In phase Ⅰ experiment, the frequency and extent of contraction of the ureteral smooth muscles were (15.85 ±3.65) times/min and (0.835 ±0.182) g; (36.35 ±9.54) times/min and (0.335 ±0.096) g, and (43. 95 ± 10. 03) times/min and (0. 320 ± 0. 096) g, respectively in the control, and 1- and 3-second electrocoagulation groups. After electrocoagulation, the frequency of muscle contraction increased significantly, and extent of contraction decreased significantly (both P= 0.000). In phase Ⅱ experiment, in 1-second electrocoagulation group, 2 cases of urine leakage were detected (2/12, 17% ) , which was cured spontaneously afterwards; the frequency and extent of ureteral contraction were (25. 58 ± 3. 20) times/min and (0.483 ±0.093) g, which were significantly lower and higher respectively than those in the 1

    Undifferentiated sarcomas are rare tumors not classified into any sarcoma subtype. Due to their rarity, imaging findings of undifferentiated sarcomas are poorly characterized. The purpose of this report was to present imaging findings of a pathologically confirmed undifferentiated sarcoma originated from the left kidney of a 12-year-old boy. The mass was infiltrative involving the renal pelvis. It mimicked massive hilar lymphadenopathy with a preserved renal contour visible by both ultrasonography and CT. Renal vein thrombosis was also observed. Although undifferentiated sarcomas are rare, they should be considered in differential diagnosis of infiltrative renal masses with renal pelvis invasion in children.

  9. Atypical twin renal arteries with altered hilar anatomy

    Full Text Available Twin renal arteries (superior and inferior were encountered on the left side in a 58-year-old male Indian cadaver. Both the renal arteries took a tortuous course to the hilum. The inferior renal artery, labeled as the accessory renal artery travelled sinuously and anteriorly over the left renal vein to enter the inferior most part of the hilum. The superior artery, labeled as main renal artery bifurcated before the hilum and its two branches were placed anterior to the vein. Thus the normal anteroposterior disposition of structures viz. renal vein, renal artery and the renal pelvis was not seen. Such renal arteries having sinuous course with atypical sequence of structures at the hilum are of worth concern to the urologists performing renal angiography and to surgeons performing laparoscopies or renal transplantation.

    The most frequent renal diseases in paediatrics include urinary tract infections, hydronephrosis, kidney anomalies and reflux. The main reason for performing DMSA scintigraphy in paediatrics is the detection of cortical abnormalities related to urinary tract infection. Because the amount of tracer retained in the tubular cells is associated with the distribution of functioning renal parenchyma in the kidney, it is possible, to evaluate the split renal function. In comparison to ultrasound and intravenous urography the sensitivity in the detection of acute as well as chronic inflammatory changes is very high, however less specific. An indication for a renography in neonates and children is beside an estimation of the total renal function and the calculation of the split renal function, the assessment of renal drainage in patients with unclear dilatation of the collecting system in ultrasound. The analysis of the time activity curve provides, especially for follow-up studies, a reproducible method to assess the urinary outflow. The diuretic scintigraphy allows the detection of urinary obstruction. Subsequently it is possible to image the micturition phase to detect vesico-ureteric reflux (indirect MCU) after drainage of tracer from the renal pelvis. An reflux in the ureters or the pelvicalyceal system is visible on the scintigraphic images and can be confirmed by time activity curves. A more invasive technique is the direct isotope cystography with bladder catheterization. The present paper should give an overview about the role of nuclear medicine in paediatric urology. (orig.)

    Objective To evaluate postoperative renal function in children with congenital moderate or severe hydronephrosis. Methods 99m Tc-labeled diethylenetriaminepenta-acetic acid scintigraphy was performed in 50 children with unilateral moderate or severe hydronephrosis to determine postoperative renal function. We also analyzed the factors influencing renal function recovery. Results Average postoperative renal function in 50 cases was 40.62%±10.09%. Among them, 32% of patients had nearly normal renal function and differentiated renal function reached up to 45%. Average preoperative and postoperative renal function in 25 cases was 23.89%±11.65% and 39.33%±8.59% respectively and the increase of renal function was about 15.44%±11.18% (P=0.0003). Renal parenchyma thickness was negatively correlated with postoperative renal function (r=-0.62, P=0.0009). The follow-up period was positively correlated with postoperative renal function (r=0.58, P=0.0026). The patients'age had no correlation with renal function recovery (r=-0.05, P=0.80). Recovery of renal function in hydronephrosis with extrarenal pelvis was greater than that in hydronephrosis with intrarenal pelvis (P=0.016). Conclusions Postoperative renal function in children with moderate or severe hydronephrosis can recover to normal. Recovery of renal function was more obvious in hydronephrosis with thinner renal parenchyma, longer follow-up period and extrarenal pelvis.

  12. Renal autotransplantation: current perspectives.

    Autotransplantation, with or without an extracorporeal renal operation, has been done 39 times in 37 patients. Indications for the procedure included severe ureteral injury in 4 patients, failed supravesical diversion in 2, renal carcinoma in a solitary kidney in 1, renovascular hypertension in 1 and donor arterial reconstruction before renal transplantation in 29. Success was obtained in all but 2 procedures, both of which involved previously operated kidneys with severe inflammation and adhesions involving the renal pelvis and pedicle. Based on our experience and a review of currently available literature we believe that renal autotransplantation and extracorporeal reconstruction can provide the best solution for patients with severe renovascular and ureteral disease not correctable by conventional operative techniques. The technique can be of particular value in removing centrally located tumors in solitary kidneys and in preparing donor kidneys with abnormal arteries for renal transplantation. The role of autotransplantation in the management of advanced renal trauma and calculus disease is less clear. A long-term comparison of patients treated by extracorporeal nephrolithotomy versus conventional lithotomy techniques will be necessary before a conclusion is reached in these disease categories.

  14. The Omo-Kibish I pelvis.

    2017-07-01

    Omo-Kibish I (Omo I) from southern Ethiopia is the oldest anatomically modern Homo sapiens skeleton currently known (196 ± 5 ka). A partial hipbone (os coxae) of Omo I was recovered more than 30 years after the first portion of the skeleton was recovered, a find which is significant because human pelves can be informative about an individual's sex, age-at-death, body size, obstetrics and parturition, and trunk morphology. Recent human pelves are distinct from earlier Pleistocene Homo spp. pelves because they are mediolaterally narrower in bispinous breadth, have more vertically oriented ilia, lack a well-developed iliac pillar, and have distinct pubic morphology. The pelvis of Omo I provides an opportunity to test whether the earliest modern humans had the pelvic morphology characteristic of modern humans today and to shed light onto the paleobiology of the earliest humans. Here, we formally describe the preservation and morphology of the Omo I hipbone, and quantitatively and qualitatively compare the hipbone to recent humans and relevant fossil Homo. The Omo I hipbone is modern human in appearance, displaying a moderate iliac tubercle (suggesting a reduced iliac pillar) and an ilium that is not as laterally flaring as earlier Homo. Among those examined in this study, the Omo I ischium is most similar in shape to (but substantially larger than) that of recent Sudanese people. Omo I has features that suggest this skeleton belonged to a female. The stature estimates in this study were derived from multiple bones from the upper and lower part of the body, and suggest that there may be differences in the upper and lower limb proportions of the earliest modern humans compared to recent humans. The large size and robusticity of the Omo I pelvis is in agreement with other studies that have found that modern human reduction in postcranial robusticity occurred later in our evolutionary history.

    2014-01-01

    Full Text Available Primary adenocarcinoma of the upper urinary tract, particularly of the ureter, is an extremely rare entity. We are reporting on the first case of metachronous appearance in one patient. The 71-year-old man underwent partial ureterectomy (R0 resection for primary adenocarcinoma of the left distal ureter. 3 years later, nephroureterectomy had to be performed because of metachronous primary adenocarcinoma of the left proximal ureter. Extensive examinations revealed no evidence for further malignancies at both times. Primary adenocarcinoma of the upper urinary tract is rare but should be kept in mind, especially in patients with chronic inflammation and urinary tract obstruction. Due to the low incidence, there is a lack of data regarding its pathogenesis, diagnosis, and optimal treatment.

  17. Calcitonin gene-related peptide (CGRP) regulates excitability and refractory period of the guinea pig ureter.

    1994-08-01

    Previous studies have indicated that calcitonin gene-related peptide (CGRP), released from the peripheral endings of capsaicin-sensitive primary afferent neurons, may play a role as an inhibitory transmitter in the guinea pig ureter. The aim of this study was to compare the effect of capsaicin desensitization and administration of a CGRP receptor antagonist on the excitability and refractory period of the guinea pig ureter to electrical field stimulation. Electrical field stimulation using a long (5 msec.) pulse width produced phasic contractions of the ureter which were unaffected by tetrodotoxin, that is, were produced through direct excitation of ureteral smooth muscle. Human alpha CGRP (1 to 10 nM.) produced a concentration-dependent transient suppression of the evoked contractions, and its effect was prevented by the CGRP receptor antagonist human alpha CGRP(8-37) (1 microM.). In vitro capsaicin pretreatment (10 microM. for 15 minutes) to block neuropeptide release from peripheral endings of sensory nerves or administration of the CGRP receptor antagonist enhanced the responsiveness of the guinea pig ureter to electrical stimulation. In control ureters, the application of two trains of electrical stimuli failed to produce a second contraction at intertrain intervals greater than 20 seconds. The intertrain interval required to obtain a second contraction averaging 50% of the amplitude of the first response (ITI50) of control ureters was about 50 seconds. In vitro capsaicin pretreatment or administration of the CGRP receptor antagonist reduced the refractory period of the ureter to electrical field stimulation: ITI50 averaged 8.8 and 9.1 seconds after capsaicin or CGRP antagonist pretreatment, respectively. These findings demonstrate that capsaicin pretreatment or blockade of CGRP receptors produced qualitatively and quantitatively similar excitatory effects on ureteral excitability and refractory period and are in general agreement with the idea that CGRP is a

    The goal of this study is to evaluate the feasibility and efficacy of percutaneous transarterial embolization for the treatment of serious renal hemorrhage after renal biopsy. Nine patients with renal hemorrhage had frank pain and gross hematuria as main symptoms after renal biopsy. Intrarenal arterial injuries and perinephric hematoma were confirmed by angiography in all cases. The arterial injuries led to two types of renal hemorrhage, Type I: severe renal injure or intrarenal renal artery rupture (n=5), with contrast medium spilling out of the artery and spreading into renal pelvis or kidney capsule in angiography; Type II, pseudo aneurysm or potential risk of intrarenal artery injure (n=4), where contrast medium that spilled out of intraartery was retained in the parenchyma as little spots less than 5 mm in diameter in angiography. Transcatheter superselective intrarenal artery embolization was performed with coils or microcoils (Type I intrarenal artery injure) and polyvinyl alcohol particles (Type II injure). The intrarenal arterial injuries were occluded successfully in all patients. Light or mild back or abdominal pain in the side of the embolized kidney was found in three patients following embolization procedures and disappeared 3 days later. Serum creatinine and perinephric hematoma were stable, and gross hematuresis stopped immediately (n=4) or 3-5 days (n=3) after embolization. In conclusions, transcatheter superselective intrarenal artery embolization as a minimally invasive therapy is safe and effective for treatment of serious renal hemorrhage following percutaneous renal biopsy.

    Renal function was studied, using radionuclide renography, in 142 patients, suffering acute obstructive pyelonephritis, in 73 of whom transcutaneous nephrostomy was applied and in 69--the ureter's stenting, for the urine passage restoration. The investigation was peformed in 1 month and 1 year after miniinvasive treatment. After comparison of the investigation results there was established, that after transcutaneous nephrostomy, using miniinvasive technologies, the affected kidney's functional inhibition was trustworthy less, than after stenting. Because of better preservation of renal function, the transcutaneous nephrostomy conduction in patients, suffering an acute obstructive pyelonephritis, constitutes a less invasive method, than the ureter's stenting.

    We retrospectively review patients who underwent ureteral implantation with a psoas hitch during obstetric or gynecologic operations and describe a new modification. Between December 1997 and May 2005, 20 patients between 26 and 56 years underwent ureteral reimplantation by using the nonrefluxing, extravesical Lich-Gregoir onlay technique with psoas hitch at our institution by the same reconstructive surgery team. Additionally, we used a urethral catheter balloon as a landmark for the bladder mucosa and fixed the bladder to the psoas tendon by using the balloon. We performed 14 ureteral reimplantations during the surgery as intraoperative reconstruction. In 6 patients, delayed reconstruction of the ureter was performed a few days following the previous operation. For intraoperative and delayed reconstructions, the mean operation time for ureteral reimplantation was 24 and 75 min. We took out the urethral catheter on the second operative day and the anastomotic drain on the third. The average hospital stay was 5.7 days. No cases of chronic flank pain, recurrent pyelonephritis, persistent severe hydronephrosis or compromised renal function occurred. No patient required reoperation. Modified psoas hitch ureteral reimplantation is an effective and safe way of reconstruction for treating defects in ureteral length. Copyright © 2010 S. Karger AG, Basel.

    Upper urinary tract tumours are exceptional in the context of renal polycystic disease. The authors report the case of Mrs B. F., 56 years old, who presented with left loin pain associated with haematuria. Clinical examination was normal and ultrasound examination revealed bilateral renal polycystic disease with a mass in the left renal sinus. CT urography showed a tumour arising from the renal pelvis suggestive of an upper urinary tract tumour. The laboratory assessment revealed normal renal function and normal urine cytology. Treatment consisted of radical nephroureterectomy with resection of a bladder cuff. Histological examination revealed a urothelial tumour of the renal pelvis with negative surgical margins. In the light of this case, the authors discuss the diagnostic difficulties and specificities, the treatment and the outcome of this unusual clinical association.

    Objective To investigate the incidence of urological malignancy in renal allograft recipients and explore the mechanism of increased incidence in China and the management. Methods A retrospective study was performed on 22 patients with urological malignancy in renal allograft recipients between 1978 and 2010. Results Twenty-two cases of urological malignancy were diagnosed by pathologic evidence, including 9 cases of transitional cell carcinoma (TCC) of bladder, 1 case of squamous cell carcinoma of bladder, 1 case of adenocarcinoma of bladder, 1 case of TCC of pelvis, 1 case of TCC of bladder and pelvis, 1 case of TCC of ureter complicated with adenocarcinoma of bladder, 2 cases of TCC of ureter, 2 cases of TCC of ureter and bladder, 3 cases of clear cell carcinoma of kidney, and 1 case of undifferentiated carcinoma of kidney. All the malignancies belonged to native organs. All the patients suffering bladder cancer had normal function of allograft. Five patients with TCC of pelvis or ureter survived and 2 cases died early after operation. All the patients suffering renal carcinoma deceased within 6 months after diagnosis. One-year survival rate was 73. 7 % after the diagnosis of urological malignancy. Conclusion Urological malignancy ranked highest in malignancy in renal allograft recipients, and rare pathological types of urological malignancy in non-renal allograft recipients are often demonstrated. The strategy of treatment should take consideration of the relationship between the usage of immunosupressive agents and the preservation of allograft function. It is critical for the therapy of malignancies to possess satisfactory allograft function. The prognosis of renal cell carcinoma is poor.%目的 分析肾移植受者泌尿系统恶性肿瘤的发病情况,并探讨其发病机理及治疗方法.方法 回顾性分析1978年至2010年12月间肾移植受者发生泌尿系统恶性肿瘤22例的资料.结果 22例的病理检查结果分别

    Full Text Available We present a case of an ectopic renal tumor in a 61-year-old morbidly obese man with a pelvic kidney found after presenting with hematuria and irritative voiding symptoms. The mass, along with the ectopic kidney and ureter, was radically resected through an open operation that involved removing both them and the renal vessels from the underlying iliac vessels. Pathological analysis demonstrated an 8.3 cm papillary renal cell carcinoma (RCC with oncocytic features, Fuhrman nuclear grade 3, with angiolymphatic invasion and negative margins. The patient has been recurrence-free for over four years since tumor resection.

  4. Techniques to resect the distal ureter in robotic/laparoscopic nephroureterectomy

    Full Text Available Treatment of clinically-organ confined high grade urothelial carcinoma of the upper tract has historically comprised open nephroureterectomy, with the distal ureter and bladder cuff mobilized through a separate open pelvic incision. To decrease morbidity, urologists have increasingly adopted laparoscopy and robotics in performing nephroureterectomy. In many published series of laparoscopic nephroureterectomy, the distal ureter and bladder cuff are detached from the bladder endoscopically by a variation of the “pluck” technique, with the resulting bladder defect left to heal by prolonged indwelling urethral catheter drainage. While the distal ureter and bladder cuff can be excised laparoscopically, it does require advanced laparoscopic skills. With the wrist articulation and stereoscopic vision in robotic surgery, robotic nephroureterectomy (RNU and bladder cuff excision can be performed in antegrade fashion to mimic the open technique together with the ability to intracorporeally close the bladder defect in a watertight, mucosa to mucosa fashion after excising the bladder cuff. In this review, we discuss the published minimally invasive techniques in resecting the distal ureter and bladder cuff during laparoscopic and RNU.

    Introduction. Laparoscopic radical nephroureterectomy (LNU) is being increasingly performed at several centers across the world. We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for upper tract transitional cell carcinoma (TCC). Results and Discussion. LNU for upper tract TCC is performed pure laparoscopically (LNU) or hand-assisted (HALNU). The management of the distal ureter is still debated. LNU appears to have superior perioperative outcomes when compared to open surgery. Intermediate term oncologic outcomes after LNU are comparable to open nephroureterectomy (ONU). Conclusions. Excision of the distal ureter and bladder cuff during nephroureterectomy remains controversial. Intermediate term oncologic outcomes for LNU compare well with ONU. Initial long-term oncologic outcomes are encouraging. Prospective randomized comparison between LNU and open surgery is needed to define the role of these modalities in the current context.

    2007-06-01

    A renal ossifying tumor of infancy is a rare event with few cases having been published, and the etiology has not yet been established. We report on two new cases of this unusual neoplasm. A 2-year-old boy presented with intermittent painless gross hematuria. After several diagnostic procedures, an open pyelolithotomy was performed and the histological diagnosis of renal tumor of infancy was finally made. The history of the second case is very similar. An 8-week-old infant presented with gross hematuria. As in the first case, an open pyelolithotomy was performed and a tumor entirely covered with blood clots was found in the renal pelvis and completely removed. A histological diagnosis of renal ossifying tumor of infancy was made. Using the literature available, the histological criteria and biological behavior are discussed, together with the diagnostic and therapeutic algorithm for this tumor. In infants with gross hematuria and a calcified (non-)invasive mass in the pelvi-calceal system, renal ossifying tumor should be considered in the differential diagnosis. MRI or CT scan offers a good diagnostic guide.

    Twenty-four young girls (mean age 13.0 years) with unilateral occlusion of a duplicated uterus and ipsilateral renal agenesis, dysplasia or hypoplasia were studied with magnetic resonance imaging (MRI) following ultrasound examination. Hydrocolpos (n=4), hydrometrocolpos (n=2), hematocolpos (n=11), hematometrocolpos (n=5), hematocolpometra, hematosalpinx (n=3) and hematometra, hematosalpinx (n=1) were noted (two of these patients had presented with hydrocolpos and hematocolpos before and after the menarche). Twenty-two of these girls presented with ipsilateral renal agenesis (right 11, left 11) with ectopic ureters to Gartner`s dust cysts (GDC) in two, in one renal hypoplasia and in one renal dysplasia with ectopic ureters to GDC. MRI offered specific images of the genital tract, showing the exact type of muellerian duct anomaly and providing high diagnostic accuracy. Such preoperative identification of a uterine anomaly, complemented with appropriate surgical intervention, can assist young girls in achieving normal fertility in the future. (orig.)

    Wakim, A; Barbet, J P; Lair-Milan, F; Dubousset, J

    1997-01-01

    By using a three-dimensional computed tomography (CT) scanner, we compared the anatomic features of the pelvis of three fetuses of same gestational age, one with a normal pelvis representing the reference model, one with classic bladder exstrophy, and one with cloacal exstrophy. The tomography slices were selected at the same levels for each case. Three angles expressing external opening of the pelvis were defined. Comparing normal and abnormal pelvises allowed definition of three criteria for the correction of the malformation: (a) the sum of the differential angles gives the amplitude of the correction needed; (b) a supraacetabular osteotomy appears to allow best closure of the pelvic ring; (c) only three slices of a CT scan are needed, which cannot be harmful, especially for neonates. Therefore, we believe that a CT scan of the pelvis should be performed whenever an osteotomy is planned in the surgical reconstruction of bladder and cloacal exstrophy.

    The Middle Pleistocene site of Sima de los Huesos in Sierra de Atapuerca, Spain, has yielded around 2,500 fossils from at least 33 different hominid individuals. These have been dated at more than 200,000 years ago and have been classified as ancestors of Neanderthals. An almost complete human male pelvis (labelled Pelvis 1) has been found, which we associate with two fragmentary femora. Pelvis 1 is robust and very broad with a very long superior pubic ramus, marked iliac flare, and a long femoral neck. This pattern is probably the primitive condition from which modern humans departed. A modern human newborn would pass through the birth canal of Pelvis 1 and this would be even larger in a female individual. We estimate the body mass of this individual at 95 kg or more. Using the cranial capacities of three specimens from Sima de los Huesos, the encephalization quotients are substantially smaller than in Neanderthals and modern humans.

    A 4-month-old boy presented with persistent gross hematuria. At ultrasonography, a 3.5-cm echogenic mass with posterior shadowing and tumor vascularity was detected within the right renal pelvis. Precontrast CT showed a slightly hyperattenuating mass in the renal pelvis. At MRI the mass was heterogeneously hypointense on T2-weighted images and isointense on T1-weighted images. Contrast-enhanced CT and MRI both revealed peripheral enhancement of the mass. A histological diagnosis of ossifying renal tumor of infancy was made after open pyelostomy and tumor enucleation. We suggest that ossifying renal tumor of infancy should be considered when a mass with posterior acoustic shadowing and tumor vascularity on US, hyperattenuation on precontrast CT and hypointensity on T2-weighted MRI is seen within the renal pelvis of an infant with hematuria.

    Actually, among of the most often neoplasm types are the cancer of prostate, bladder and intestine. The incidence of the intestine neoplasm in Brazil is at fourth among the most frequent tumors of the male sex, barely close to the stomach, lung and prostate incidences. Phantoms are objects used as simulators for investigating ionizing radiation transport on humans, especially during radiation therapy or radiological diagnostic. The purpose of this work is the achievement of a set of computerized tomography (CT) images of a male pelvis phantom, with anthropomorphic and anthropometric features. It investigates and analyses the set of phantom CT images in according to a correspondent human pelvis one. The reason to develop a pelvis phantom is the needs of reproducing well established spatial dose distribution in radiation therapy, especially during calibration and protocol setup for various pelvis neoplasms. It aims to produce dose optimization on radiation therapy, improving health tissue protection and keeping control tumor dose. A male pelvis phantom with similar shape made of equivalent tissues was built for simulating the ionizing radiation transport to the human body. At the phantom, pelvis organs were reproduced including the bladder, the intestine, the prostate, the muscular and greasy tissue, as well as the bone tissue and the skin. A set of CT images was carried out in axial thin sections of 2mm thickness. As results, the constituent tissues had a tomography response on Hounsfield scale similar to values found on the human pelvis. Each tissue has its respective Hounsfield value, demonstrated here. The CT images also show that the organs have equivalent anthropometric measures and anthropomorphic features of the radiological human anatomy. The anatomical physical arrangement of the organs is also similar to of the pelvis human male, having the scales of gray and numerical scale of Hounsfield compatible with the scale of the human tissue. The phantom presents

    Crossed renal ectopia is an uncommon developmental anomaly in which both kidneys are located on the same side of the body. The present case describes a 20-year-old man who underwent the military entrance physical examination. The ultrasound showed the right kidney in normal site with slightly increased size, but the left kidney was not identified. Tc-MAG3 scan showed a single kidney with 2 ureters, and the orifices of the ureters were connected at both sides of bladder. Tc-DMSA SPECT and contrast-enhanced multidetector CT were performed and revealed crossed fused renal ectopia.

    Full Text Available Introduction A duplicated renal collecting system is a relatively common congenital anomaly rarely presenting in adults. Aim In this video we demonstrate our step-by-step technique of Robotic heminephrectomy in a patient with non-functioning upper pole moiety. Materials and Methods Following cystoscopy and ureteral catheter insertion the patient was placed in 600 modified flank position with the ipsilateral arm positioned at the side of the patient. A straight-line, three arm robotic port configuration was employed. The robot was docked at a 90-degree angle, perpendicular to the patient. Following mobilization the colon and identifying both ureters of the duplicated system, the ureters were followed cephalically toward, hilar vessels where the hilar anatomy was identified. The nonfunctioning pole vasculature was ligated using hem-o-lok clips. The ureter was sharply divided and the proximal ureteral stump was passed posterior the renal hilum. Ureteral stump was used as for retraction and heminephrectomy is completed along the line demarcating the upper and lower pole moieties. Renorrhaphy was performed using 0-Vicryl suture with a CT-1 needle. The nonfunctioning pole ureter was then dissected caudally toward the bladder hiatus, ligated using clips, and transected. Results The operating time was 240 minutes and blood loss was 100 cc. There was no complication post-operatively. Conclusions Wrist articulation and degree of freedom offered by robotic platform facilitates successful performance of minimally invasive heminephrectomy in the setting of an atrophic and symptomatic renal segment.

    Between 1949 and 1974, 449 patients with bladder cancer were treated by radical cystectomy either alone (137 patients), or following three preoperative radiation schemes (312 patients). True pelvis irradiation was delivered either 4000 cGy (rad) over 4 weeks in 119 patients, or 2000 cGy over 1 week in 86 patients; radical cystectomy was performed after periods averaging 6 weeks and 2 days, respectively. Whole pelvic irradiation of 2000 cGy in 5 consecutive days was given to 107 patients who underwent cystectomy within 2 days later. Five-year survival rates for low-stage TIS-T/sub 2/ tumors of low histologic grade were 60-66% in the four treatment groups. The 5-year survival for high-stage tumors of high histologic grade, mainly in T/sub 3/ patients, was 9% in the cystectomy alone patients versus 24-32% in the preoperatively irradiated patients. The 5-year survival rates for high-stage low-grade and low-stage high-grade tumors, were 30% in the cystectomy alone group and 39-51% in the preoperative irradiation groups; the more favorable survival was noted in the whole pelvic irradiation group, which included 18% 5-year survivals for T/sub 4/ patients. Pelvic recurrence was reduced from 28% after cystectomy alone to 14-16% with true pelvis irradiation and 8% with whole pelvic irradiation. The reduced incidence of local recurrence, observed mainly in high stage or high grade tumors, was associated with tumor downstaging after irradiation. Extrapelvic metastases developed in 21-35% of the four treatment groups, underlining the inadequacy of the local radiation and surgical treatment in preventing subsequent distant spread.

    Full Text Available Introduction: Management of renal stones in children with a solitary kidney is a challenge. In the current study, the efficacy and safety of retrograde intrarenal surgery (RIRS in these children were determined. Patients and Methods: Records of children with renal stones who were treated at our institute between August 2011 and August 2014 were retrospectively assessed. Inclusion criteria were: Children with single renal stone <2 cm size, in a solitary kidney. A 7.5 Fr flexible ureteroscope (FURS was introduced into the ureter over a hydrophilic guidewire under visual and fluoroscopic guidance - applying a back-loading technique. The stone was completely dusted using 200 μm laser fiber (0.2-0.8 joules power and10-30 Hz frequency. At the end of the maneuver, a 5 Fr JJ stent was inserted into the ureter. The children were discharged home 24 h postoperative - provided that no complications were detected. Results: Fourteen children (3 girls and 11 boys with median age 9.5 years (range 6-12 were included. The mean stone burden was 12.2 ± 1.5 mm (range 9-20. Stones were successfully accessed in all of the cases by the FURS except for 2 cases in whom a JJ stent was inserted into the ureter and left in place for 2 weeks to achieve passive dilatation. All of the stones were dusted completely. The immediate postoperative stone-free rate (SFR was 79%, and the final SFR was 100% after 3 weeks. No intraoperative complications were observed. Conclusions: RIRS for renal stone <2 cm in children with a solitary kidney is a single-session procedure with a high SFR, low complication rate, and is a minimally invasive, natural orifice technique.

  1. Cytokeratin 15 marks basal epithelia in developing ureters and is upregulated in a subset of urothelial cell carcinomas.

    Full Text Available The mammalian ureter contains a water-tight epithelium surrounded by smooth muscle. Key molecules have been defined which regulate ureteric bud initiation and drive the differentiation of ureteric mesenchyme into peristaltic smooth muscle. Less is known about mechanisms underlying the developmental patterning of the multilayered epithelium characterising the mature ureter. In skin, which also contains a multilayered epithelium, cytokeratin 15 (CK15, an acidic intermediate filament protein, marks cells whose progeny contribute to epidermal regeneration following wounding. Moreover, CK15+ precursor cells in skin can give rise to basal cell carcinomas. In the current study, using transcriptome microarrays of embryonic wild type mouse ureters, Krt15, coding for CK15, was detected. Quantitative polymerase chain reaction analyses confirmed the initial finding and demonstrated that Krt15 levels increased during the fetal period when the ureteric epithelium becomes multilayered. CK15 protein was undetectable in the ureteric bud, the rudiment from which the ureter grows. Nevertheless, later in fetal development, CK15 was immunodetected in a subset of basal urothelial cells in the ureteric stalk. Superficial epithelial cells, including those positive for the differentiation marker uroplakin III, were CK15-. Transformation-related protein 63 (P63 has been implicated in epithelial differentiation in murine fetal urinary bladders. In wild type fetal ureters, CK15+ cells were positive for P63, and p63 homozygous null mutant ureters lacked CK15+ cells. In these mutant ureters, sections of the urothelium were monolayered versus the uniform multilayering found in wild type littermates. Human urothelial cell carcinomas account for considerable morbidity and mortality. CK15 was upregulated in a subset of invasive ureteric and urinary bladder cancers. Thus, in ureter development, the absence of CK15 is associated with a structurally simplified urothelium whereas

    The authors report two cases of recurrent transitional cell carcinoma at the anastomotic site of the ileal conduit and ureter after total cystectomy. In one patient, a recurrent tumor was also found in the distal ureter which had not been removed during previous nephrectomy. At follow up, the patients presented with gross hematuria or hydronephrosis, and the presence of mass lesions was demostarted by intravenous urography, antegrade pyelography, and/or loopography. Transitional cell carcinoma was diagnosed by surgery and pathologic examination.

    Objective: To review the epidemiological feature, clinical and diagnostic data of post-traumatic diaphragmatic hernia (TDH) associated with pelvis fracture reported in recent 10 years.Methods: A 10-year retrospective study was undertaken to analyze the incidence, diagnosis, management, morbidity and mortality of patients with traumatic diaphragmatic hernia associated with pelvis fractures. A total of 46 cases in our country were reviewed.Results: The incidence of TDH associated with pelvis fractures was relatively rare and the diagnosis was often delayed or missed. A total of 72.34% of these patients were diagnosed as TDH associated with pelvis fractures after injury for 36 hours to 1 week. Although the trans-thorax approach was preferred for surgical closure in the acute phase, its mortality still reached 8.51%.Conclusions: TDH associated with pelvis fractures is difficult to be diagnosed because of its varied clinical and radiological signs and the patients may not present with symptoms for a long time after injury. In clinical, a high index of suspicion with appropriate examination is the mainstay of management, which can be helpful in prognosis.

    Objective To analyze the risk factors causing postoperative urosepsis in ureter endoscopic lithotripsy without infection preoperatively, in order to make a more effective and safer preventive and therapeutic strategy. Methods From January 2010 to January 2015, 5 ureteral calculus patients undergoing ureter endoscopic lithotripsy with holmium laser were retrospectively enrolled in this clinical study. These patients suffered urosepsis postoperatively confirmed by the clinical presentations and laboratory results, while they had no infection in their blood and urine preoperatively. Without delay, 5 patients were treated by anti-inflammation and anti-shock. Results The vasopressor drug was stopped gradually after 12-36 hours. The body temperature was recovered to normal in 2 or 3 days, and the blood and urine test results were not abnormal in 7 days. At last, 5 patients were all cured. Conclusions Stone and operation themselves are potential factors to cause urosepsis after ureter endoscopic lithotripsy. Especially for patients who had not presented infection preoperatively, careful preparation preoperatively, corrective manipulation, low pressure irrigation, drainage and controlling time during operation, and early diagnosis, appropriate treatment postoperatively are the key to cure and prevent urosepsis.

    Full Text Available Abstract Background Three kidney systems appear during vertebrate development: the pronephroi, mesonephroi and metanephroi. The pronephric duct is the first or primary ureter of these kidney systems. Its role as a key player in the induction of nephrogenic mesenchyme is well established. Here we investigate whether the duct is involved in urine modification using larvae of the freshwater amphibian Ambystoma mexicanum (axolotl as model. Results We investigated structural as well as physiological properties of the pronephric duct. The key elements of our methodology were: using histology, light and transmission electron microscopy as well as confocal laser scanning microscopy on fixed tissue and applying the microperfusion technique on isolated pronephric ducts in combination with single cell microelectrode impalements. Our data show that the fully differentiated pronephric duct is composed of a single layered epithelium consisting of one cell type comparable to the principal cell of the renal collecting duct system. The cells are characterized by a prominent basolateral labyrinth and a relatively smooth apical surface with one central cilium. Cellular impalements demonstrate the presence of apical Na+ and K+ conductances, as well as a large K+ conductance in the basolateral cell membrane. Immunolabeling experiments indicate heavy expression of Na+/K+-ATPase in the basolateral labyrinth. Conclusions We propose that the pronephric duct is important for the subsequent modification of urine produced by the pronephros. Our results indicate that it reabsorbs sodium and secretes potassium via channels present in the apical cell membrane with the driving force for ion movement provided by the Na+/K+ pump. This is to our knowledge the first characterization of the pronephric duct, the precursor of the collecting duct system, which provides a model of cell structure and basic mechanisms for ion transport. Such information may be important in understanding

    A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used. Although considered to be accompanied with risks of bleeding, bowel injury, and renal dysfunction, PNL is effective for urinary lithiasis after renal transplantation. TUL is less invasive, but access may be difficult when the ureter has an unusual course or ureteral stricture exists, as in our patient.

    We report a case of a 24-year-old male patient with cystic dilatation of the seminal vesicle associated with renal agenesis and megaureter. This patient complained of left renal colic with pollakiuria. We performed intravenous urography and ultrasound showed a cyst in the seminal vesicle associated with left megaureter and right renal agenesis. Treatment consisted of resection of the cyst and reimplantation of the left ureter into the bladder. No postoperative complications were observed. This association is rare and can be explained by the common embryological origin of the seminal vesicle and kidney and ureter. Its diagnosis is now facilitated by ultrasound and CT. The treatment of this tumor is surgical only when the lesions are responsible for clinical symptoms.

    The distinction of pain in pregnancy due to urolithiasis from that related to physiological dilation of the renal tract is a common conundrum as renal colic is one of the commonest causes for non-obstetric pain in pregnancy. Ultrasound is the first-line imaging test but although it may demonstrate renal dilation, it may not show the cause. Magnetic resonance imaging (MRI) is able to make the distinction. Physiological dilation will show smooth tapering of the ureter in the middle third as it is compressed between the gravid uterus and the retroperitoneum. Obstruction due to calculi causes renal enlargement and perinephric oedema. When a stone is lodged in the lower ureter, a standing column of dilated ureter will be seen below the physiological constriction. The stone itself may be shown. Computed tomography (CT) is an acceptable alternative if there is a contraindication to MRI, but even low-dose regimes involve some ionising radiation. This paper serves to highlight the role of MRI compared to US and CT in the imaging of renal colic in pregnancy. Multidisciplinary collaboration between obstetricians, urologists, and radiologists is required for effective management.

    The pelvis is an essential element in the study of scoliosis since it constitutes the base of the spine and its orientation may affects postural balance. In order to study the role of the pelvis in the evolution and treatment of this disease, a new technique for the 3D personalised reconstruction of the pelvis was developed. It consists in identifying and digitizing 19 pelvic anatomical landmarks on postero-anterior and lateral x-rays and to reconstruct them in 3D with two techniques: the DLT algorithm developed by Marzan (1976) and, for 6 of the 19 landmarks, an adaptation of it called DLT with confidence coefficients. The latter takes into account the confidence given to the identification of the landmarks on each x-rays. Two methods were used to validate the reconstruction of the pelvis. The first one, used for 11 scoliotic patients and 2 dry pelvis specimens, consists in applying the reconstruction algorithm in an inverse way on the 3D coordinates of the reconstructed landmarks to obtain their 2D retroprojection on the x-ray planes, and thus comparing the retroprojected coordinates with the 2D digitized coordinates. The second method consists in measuring a dry pelvis specimen and comparing the 3D measured landmarks with the ones reconstructed with the x-rays of this specimen. For the first validation, results have shown that the lowest retroprojection errors (less than 2.5 +/- 2.6 mm) for the scoliotic patient group are located on the superior base of the sacrum, on the sacral curve and on the acetabula, while the highest (6.4 +/- 7.2 mm) were on the iliac crests. For the dry specimens, the retroprojection errors were below the millimeter. The second validation method showed 3D differences of 2.4 +/- 1.2 mm between measured and reconstructed landmarks of a dry specimen, which is of the same order of magnitude as what is reported in the literature for vertebrae. The reconstruction of the pelvis is thus considered adequate and its graphical wireframe

    Objective: To evaluate age-dependent changes in fetal kidney measurements with MRI. Patients and methods: Fetal MRI examinations were used to study the kidney length (218 fetuses), signal intensities of renal tissue, renal pelvis, and liver tissue on T2-weighted images (223 fetuses), and the whole-kidney apparent diffusion coefficient (107 fetuses). A 1.5 T superconducting unit with a phased array coil was used in patients from 16 to 39 weeks' gestation. The imaging protocol included T2-weighted single-shot fast spin-echo, T2-weighted balanced angiography and diffusion-weighted sequences. Slice thickness ranged from 3 to 5 mm. Results: Fetal kidney length as a function of gestational age was expressed by the linear regression: kidney length (mm) = 0.190 x gestational age (d) - 8.034 (R {sup 2} 0.883, p < 0.001). Paired t-test analysis showed a highly statistically significant difference between the ratio of renal tissue signal intensity to renal pelvis signal intensity and the ratio of liver signal intensity to renal pelvis signal intensity on T2-weighted images (t = -50.963, d.f. = 162, p < 0.001), with renal tissue hyperintense to liver tissue. The apparent diffusion coefficient in relation to gestational age was described by the equation: ADC ({mu}m{sup 2}/s) = 0.0302 x square (gestational age (d)) - 14.202 x gestational age (d) + 2728.6 (R {sup 2} = 0.225, p < 0.001). Conclusion: The length, signal intensity on T2-weighted images, and apparent diffusion coefficient of the fetal kidney change significantly with gestational age. The presented data may help in the prenatal diagnosis of renal anomalies.

  13. The coordinated movement of the spine and pelvis during running.

    Previous research into running has demonstrated consistent patterns in pelvic, lumbar and thoracic motions between different human runners. However, to date, there has been limited attempt to explain why observed coordination patterns emerge and how they may relate to centre of mass (CoM) motion. In this study, kinematic data were collected from the thorax, lumbar spine, pelvis and lower limbs during over ground running in n=28 participants. These data was subsequently used to develop a theoretical understanding of the coordination of the spine and pelvis in all three body planes during the stance phase of running. In the sagittal plane, there appeared to be an antiphase coordinate pattern which may function to increase femoral inclination at toe off whilst minimising anterior-posterior accelerations of the CoM. In the medio-lateral direction, CoM motion appears to facilitate transition to the contralateral foot. However, an antiphase coordination pattern was also observed, most likely to minimise unnecessary accelerations of the CoM. In the transverse plane, motion of the pelvis was observed to lag slightly behind that of the thorax. However, it is possible that the close coupling between these two segments facilitates the thoracic rotation required to passively drive arm motion. This is the first study to provide a full biomechanical rationale for the coordination of the spine and pelvis during human running. This insight should help clinicians develop an improved understanding of how spinal and pelvic motions may contribute to, or result from, common running injuries.

    The ability to determine sex from unknown skeletal remains is vital, and methods to do this on the various bones of the human skeleton have been researched extensively. Many researchers have emphasized the need for population specific data for methods which are based on measurements, as there are vast differences in body size in various populations. The pelvis is known to be the most sexually dimorphic part of the human body, and no discriminant function formulae for this bone are available for Greek or other Mediterranean groups. The purpose of this study was therefore to develop discriminant functions which can be used for sex determination on measurements of the pelvis of modern Greeks. A sample of 97 male and 95 female pelves in a skeletal collection housed in Heraklion, Crete, was used. Measurements were taken from the articulated pelvis, single os coxae and the sacrum. Discriminant function formulae for all measurements and various combinations were used in order to assess the degree of sexual dimorphism in various parts of the pelvis, and to make the formulae usable on fragmented remains. For the single os coxae, average accuracies of 79.7-95.4% (79.1-93.5% on cross-validation) were found. However, it was found that measurements of the sciatic notch were unreliable and yielded poor results, and it is advisable that this characteristic must only be used as a last resort. Dimensions of the sacrum were not very dimorphic (average accuracy 60.9%), while measurements from the articulated pelvis yielded poorer results than that from single innominate bones. The diameter of the acetabulum was the single most dimorphic characteristic, providing on average 83.9% accuracy when used in isolation.

    Abstract Objective: To describe the management of the distal ureter during radical nephroureterectomy with the transvesical laparoendoscopic single-site surgery (T-LESS) approach. Methods: Between January 2010 and October 2013, five patients underwent laparoscopic radical nephroureterectomy for upper urinary tract carcinoma (UTUC) with the T-LESS approach. Patients were placed in the supine position. A 2.5-cm skin incision was made in the line between the pubis and the umbilicus. The bladder was identified and a multiport was inserted into the bladder. The patients were repositioned to a lateral decubitus position; pneumovesicum was established and the ureteral openings were identified. We marked the bladder cuff with electrocautery all the way through to the extravesical fat. The bladder defect was sealed with sutures. After checking for any leak or bleeding, the multiport was removed and the bladder was closed. At this point, we continued with nephrectomy by standard laparoscopy or LESS. A 18F Foley catheter was placed into the bladder. Results: The mean age was 70 years (range 58-81 years), the mean operative time was 198 minutes (range 115-390 minutes), the mean time for the management of the distal ureter was 35 minutes (range 27-45 minutes), the mean estimated blood loss was 234 mL (range 60-850 mL), and the mean hospital stay was 3.8 days (range 2-8 days). In all patients the bladder cuff was free of disease. Conclusion: The transvesical laparoendoscopic single-site approach to the distal ureter for UTUC appears safe and reproducible, with faster closure of the bladder defect and improved cosmesis.

  7. Hydrogen sulfide plays a key role in the inhibitory neurotransmission to the pig intravesical ureter.

    Full Text Available According to previous observations nitric oxide (NO, as well as an unknown nature mediator are involved in the inhibitory neurotransmission to the intravesical ureter. This study investigates the hydrogen sulfide (H2S role in the neurogenic relaxation of the pig intravesical ureter. We have performed western blot and immunohistochemistry to study the expression of the H2S synthesis enzymes cystathionine γ-lyase (CSE and cystathionine β-synthase (CBS, measurement of enzymatic production of H2S and myographic studies for isometric force recording. Immunohistochemical assays showed a high CSE expression in the intravesical ureter muscular layer, as well as a strong CSE-immunoreactivity within nerve fibres distributed along smooth muscle bundles. CBS expression, however, was not consistently observed. On ureteral strips precontracted with thromboxane A2 analogue U46619, electrical field stimulation (EFS and the H2S donor P-(4-methoxyphenyl-P-4-morpholinylphosphinodithioic acid (GYY4137 evoked frequency- and concentration-dependent relaxations. CSE inhibition with DL-propargylglycine (PPG reduced EFS-elicited responses and a combined blockade of both CSE and NO synthase (NOS with, respectively, PPG and NG-nitro-L-arginine (L-NOARG, greatly reduced such relaxations. Endogenous H2S production rate was reduced by PPG, rescued by addition of GYY4137 and was not changed by L-NOARG. EFS and GYY4137 relaxations were also reduced by capsaicin-sensitive primary afferents (CSPA desensitization with capsaicin and blockade of ATP-dependent K+ (KATP channels, transient receptor potential A1 (TRPA1, transient receptor potential vanilloid 1 (TRPV1, vasoactive intestinal peptide/pituitary adenylyl cyclase-activating polypeptide (VIP/PACAP and calcitonin gene-related peptide (CGRP receptors with glibenclamide, HC030031, AMG9810, PACAP6-38 and CGRP8-37, respectively. These results suggest that H2S, synthesized by CSE, is involved in the inhibitory neurotransmission

    We present four cases of transitional cell carcinoma of the transplant ureter (TCCtu). In three cases, localized tumor resection and a variety of reconstructive techniques were possible. Transplant nephrectomy with cystectomy was performed as a secondary treatment in one locally excised case. Transplant nephroureterectomy was performed as primary treatment in one case. The role of oncogenic viruses and genetic fingerprinting to determine the origin of TCCtu are described. Our cases and a systematic literature review illustrate the surgical, nephrological, and oncological challenges of this uncommon but important condition.

    2014-11-01

    Traditional treatment of upper tract transitional cell carcinoma (TCC) is nephroureterectomy with a bladder cuff. This is in keeping with the nature of the disease, in that TCC is a panurothelial disease. However, there are a few rare occasions when this would mean making a subject anephric, as in a TCC in a solitary kidney or bilateral synchronous/metachronous disease. We present a case of a patient with a dysplastic, poorly functioning left kidney and with a TCC of the ureter on the right side.

  11. Acute renal failure after ingestion of guaifenesin and dextromethorphan.

    2014-07-01

    Guaifenesin is a common nonprescription medication that has been implicated in drug-induced nephrolithiasis. Dextromethorphan, a nonprescription antitussive found in some guaifenesin-containing preparations, is increasingly recognized as a substance of abuse by many youth and young adults. Renally excreted medications known to have poor solubility in urine have the potential to precipitate when ingested in large quantity, leading to acute obstruction of the ureters and renal failure. We describe the case of a 22-year-old male who developed severe bilateral flank pain, hematuria, and oliguria after an isolated recreational ingestion of guaifenesin and dextromethorphan. The patient was found to have bilateral ureteral obstruction and acute renal failure, suspected to be secondary to precipitation of medication metabolites in the urine. This case highlights the potential for acute renal failure secondary to guaifenesin and dextromethorphan abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Apresentamos uma revisão sobre trauma renal, com ênfase na avaliação radiológica, particularmente com o uso da tomografia computadorizada, que tem se tornado o exame de eleição, ao invés da urografia excretora e arteriografia. O sucesso no tratamento conservador dos pacientes com trauma renal depende de um acurado estadiamento da extensão da lesão, classificado de acordo com a Organ Injury Scaling do Colégio Americano de Cirurgiões. O tratamento conservador não-operatório é seguro e consiste de observação contínua, repouso no leito, hidratação endovenosa adequada e antibioti- coterapia profilática, evitando-se uma exploração cirúrgica desnecessária e possível perda renal. As indicações para exploração cirúrgica imediata são abdome agudo, rápida queda do hematócrito ou lesões associadas determinadas na avaliação radiológica. Quando indicada, a exploração renal após controle vascular prévio é segura, permitindo cuidadosa inspeção do rim e sua reconstrução com sucesso, reduzindo a probabilidade de nefrectomia.We present a revision of the renal trauma with emphasis in the radiographic evaluation, particularly CT scan that it has largely replaced the excretory urogram and arteriogram in the diagnostic worh-up and management of the patient with renal trauma. The successful management of renal injuries depends upon the accurate assessment of their extent in agreement with Organ Injury Scaling classification. The conservative therapy managed by careful continuous observation, bed rest, appropriate fluid ressuscitation and prophylactic antibiotic coverage after radiographic staging for severely injured kidneys can yield favorable results and save patients from unnecessary exploration and possible renal loss. The indications for immediate exploratory laparotomy were acute abdomen, rapidly dropping hematocrit or associated injuries as determinated from radiologic evaluation.

    Microvascular surgical techniques of renal transplant in rats have evolved over the past 5 decades to achieve successful rat renal transplant; these modifications have included surgical techniques to address the anatomic variations in the renal blood vessels and those to reduce ischemic and operation durations. Here, we review the surgical techniques of renal transplant in rats and evaluate the advantages and disadvantages of individual techniques of vascular and ureteric anastomoses. For this review, we performed a systematic literature search using relevant medical subject heading terms and included appropriate publications in the review. Since the first description of a rat model of renal transplant by Bernard Fisher and his colleagues in 1965, which used end-to-side anastomosis between the renal vein and renal artery to the recipient inferior vena cava and aorta, several vascular and ureteric anastomosis techniques have been modified. Vascular anastomosis techniques now include end-to-end anastomosis, use of donor aortic and inferior vena cava conduits, sleeve and cuff anastomoses, and application of fibrin glue. Likewise, restoration of the urinary tract can now be achieved by direct anastomosis of the donor ureter to the recipient bladder, end-to-end anastomosis between the donor and recipient ureters, and donor bladder cuff to the recipient bladder. There are advantages and disadvantages attributable to individual techniques. The range of vascular and ureteric anastomosis techniques that has emerged reflects the need for mastering more than one technique to suit the vascular anatomy of individual animals and to reduce operating time for achieving successful outcomes after renal transplant.

    Transitional-cell carcinoma (TCC) of the upper tract in a case of circumcaval ureter (CCU) is a rare entity. Laparoscopic transperitoneal nephroureterectomy in such case represents a unique challenge in the era of minimally invasive surgery. We report a case of complete transperitoneal laparoscopic nephroureterectomy with bladder cuff excision done for TCC in a case of CCU. This case report describes the first point of technique of the procedure done for this rare entity. A 38-year-old male patient underwent the procedure for high-grade TCC of right lower calix. The essential tenets of the procedure included performance of the technique in a manner contrary to the conventional nephroureterectomy. The case report describes the procedure in the following steps: management of lower ureter and bladder cuff followed upper tract procedure after transposition of bladder cuff posterior to inferior vena cava. The procedure was accomplished utilizing four ports and a 6 cm Pfannenstiel incision with operative time of 220 minutes and blood loss of 50 mL.

    @@ Leiomyosarcoma most frequently arises in the retroperitoneum, the intra-abdominal space, and the subcutaneous tissue of the extremities. Primary leiomyosarcoma of bone is a rare malignant neoplasm, most commonly involving bones around the knee.~1 Although whether leiomyosarcoma can be considered a true primary bone tumor remains questionable, refinements in immunohistochemical techniques are causing this recognition to slowly gain favor. We report a case of a huge primary leiomyosarcoma of bone in the right pelvis.

    Three dead dogs were brought to the College of Veterinary Medicine, Kyungpook National University for study. Clinically, all the dogs showed emaciation, anorexia, depression, hemorrhagic vomiting and diarrhea for 7-10 days before death. All the clinical signs were first noted for about one month after feeding the dogs with commercial diets. At necropsy, all 3 dogs had severe renal damage with the same green-yellowish colored nephroliths in the renal pelvis. They also showed systemic hemorrhage and calcification of several organs, which might have been induced by uremia. Microscopically, necrosis, calcification and calculi were detected in the renal tubules, and especially in the proximal convoluted tubules and collecting ducts of the kidney. These findings were supportive of a mycotoxic effect, and especially on their kidneys. However, the precise cause of the toxic effect in these cases of canine renal failure could not be determined.

    Full Text Available Background/Objective: Ultrasonography has replaced roentgenography in recent obstetric practice. X-ray pelvimetry in the management of vaginal delivery in patients with previous cesarean section is the only exception in some centers. There has been no report of the prevalence of four major pelvic types in Iranian females before this study."nPatients and Methods: In this study, we evaluated the types of pelvis and pelvic measurements of 185 adult female patients in four different regional municipalities of Mashhad. AP pelvic x-ray was performed for all the patients. All images were reported by a radiologist."nResults: Gynecoid pelvis was the most common pelvic type (88.6% followed by platyploid (7.6%, android (2.7% and anthropoid (1.1%. The results including the types of pelvis and the measurements had significant differences with previous studies in western countries. There were no significant differences in the prevalence of pelvic types between different imaging centers, different age groups and nulliparous vs. parous patients. "nConclusion: The prevalence of pelvic types depends on human race but it does not appear to be influenced by parity or age.

    The aim of this study was to evaluate time dependent changes in 3 dimensional (3D) thorax and pelvis kinematics during an intense 60 min bike ride. 10 experienced male road cyclists pedalled for 60 min at workloads based on previous onset of blood lactate accumulation (OBLA) testing. The 60 min cycle was divided into six 10 min periods consisting of 8 min of steady state cycling (88% of OBLA) followed by 90 s at 140% of OBLA and a 30 s recovery phase (60% of OBLA). Thorax and pelvis kinematic data were recorded from 20 consecutive pedal revolutions using a 3D motion capture system (200 Hz) during each steady state phase. Repeated measures ANOVA with Bonferroni corrections were used to test for effects of test duration on segmental kinematics. Results indicated an effect for test duration on the mean thorax (pthorax and pelvis orientation, increased lateral thoracic movements and pelvic lateral tilt velocities. © Georg Thieme Verlag KG Stuttgart · New York.

    Objective is to identify epidemiologic and radiologic criteria allowing specific diagnoses of tumors and tumor-like lesions in the hip region and pelvis, and to optimize pre-operative staging. Patients with pelvic tumors are usually older, and their tumors are larger relative to patients with tumors in extremities. The majority of tumors in the pelvis are malignant (metastases, myeloma, chondrosarcoma, Ewing-, osteo-, and MFH/fibrosarcoma), while those in the proximal femur are in majority benign (fibrous dysplasia, solitary bone cyst, and osteoid osteoma). Soft tissue masses in the thigh in the elderly are typically sarcomas without tumor specific signs. Common tumor-like lesions occurring in the hip and pelvis that can mimic neoplasm are: infections (including tuberculosis), insufficiency/avulsion fractures, cysts, fibrous dysplasia, aneurysmal bone cyst, Langerhans cell histiocytosis, and Paget's disease. Local MR staging is based on the compartmental anatomy. The psoas and gluteal muscles are easily invaded by sarcoma originating in the ileum. The pectineus muscle protects the neurovascular bundle at the level of the hip. The thigh is separated into three compartments, some structures (Sartorius muscle) cross borders between compartments. Immobile joints (SI-joints, osteoarthritic hip) are relatively easily crossed by sarcoma and giant cell tumor.

    Idiopathic retroperitoneal fibrosis (RPF) is a rare disease entity and its etiology is uncertain. We report two similar cases which showed an uncommon presentation of idiopathic RPF. A 66-year-old woman and an 80-year-old man presented with incidental findings of left renal pelvic mass-like lesions. Computed tomography revealed a soft tissue density mass replacing the left renal pelvis, which was suspicious for renal pelvic cancer, and the diagnosis of idiopathic RPF was surgically confirmed. To the best of our knowledge, a few cases of idiopathic RPF presenting with features of a localized unilateral renal pelvic mass mimicking renal pelvic cancer have been reported.

    To analyze and evaluate our experience in surgical treatment with the open approach of the complex ureteral stenosis after adult kidney transplantation in a tertiary level hospital in the last seven years. We have reviewed the different surgical options used. A total of 589 consecutive adult renal transplants were performed from January 2005 to December 2012. Of these, 1.1% showed some degree of symptomatic obstructive uropathy which after initial urinary diversion required open surgical approach using the ipsilateral or contralateral native urinary tract. Characteristics of the patient, clinical examinations performed and surgical technique performed as well as their results are presented. During the period under review, in 5 men and 2 women who had ureteral stenoses after renal transplant, 7 reparative surgeries were performed by open ureteropyelostomy, using ipsilateral native ureter in 6 cases and contralateral ureter in the remaining case. In one case, uretero-calicial anastomosis was performed due to severe pyelic shrinkage. There were no significant complications. Native kidney nephrectomy was not required for further complications. All the patients operated on had optimum plasma creatinine levels with resolution of previous dilatation. The initial percutaneous nephrostomy followed by open surgical repair using native ureter represents a definitive, valid and optimal alternative in terms of safety and preservation of renal function.

    Conclusion: The first report of 3 encrusted stents within the same ureter is presented. The prevention of JJ stent encrustation is crucial via adequate and appropriate patient counselling. In most patients with forgotten encrusted stents who qualify for endoscopic management, a multi-modality approach is required.

    This study provides information about baseline mechanical properties of the entire muscle and the molecular contractile mechanism in human ureter smooth muscle and proposed to investigate if changes in mechanical motor performance in different regions of isolated human ureter are attributable to differences in myosin crossbridge interactions. Classic mechanical, contraction and energetic parameters derived from the tension-velocity relationship were studied in ureteral smooth muscle strips oriented longitudinally and circularly from abdominal and pelvic human ureter parts. By applying of Huxley's mathematical model we calculated the total working crossbridge number per mm(2) (Ψ), elementary force per single crossbridge (Π0), duration of maximum rate constant of crossbridge attachment 1/f1 and detachment 1/g2 and peak mechanical efficiency (Eff.max). Abdominal longitudinal smooth muscle strips exhibited significantly higher maximum isometric tension and faster maximum unloaded shortening velocity compared to pelvic ones. Contractile differences were associated with significantly higher crossbridge number per mm(2). Abdominal longitudinal muscle strips showed a lower duration of maximum rate constant of crossbridge attachment and detachment and higher peak mechanical efficiency than pelvic ones. Such data suggest that the abdominal human ureter showed better mechanical motor performance mainly related to a higher crossbridge number and crossbridge kinetics differences. Such results were more evident in the longitudinal rather than in the circular layer.

    Full Text Available We report on a case of urothelial carcinoma (UC with lipid cell and micropapillary variants in the ureter. A 64-year-old man presented with gross hematuria. Urinary cytology revealed the presence of atypical urothelial cells. Computed tomography and drip infusion/retrograde pyelography identified a mass-occupying lesion in the left mid-ureter, as well as left hydronephrosis. A clinical diagnosis of left ureteral cancer was given and the patient underwent left nephroureterectomy. Microscopically, the major component of the tumor was a conventional high-grade UC. In the invasive region, however, lipid cell and micropapillary variants of UC were also observed. Upon immunohistochemical analysis, all of the components were diffusely positive for cytokeratin 7 and p53. Intense membranous expression of human epidermal growth factor receptor 2 (HER2 was also observed in both the lipid cell and micropapillary variants of UC, whereas weak and incomplete staining was observed in most regions of the conventional UC. The pathological stage was pT3 N2. Multiple times, the patient experienced recurrence of the UC in the urinary bladder and urethra. Although the patient underwent total cystectomy and urethrectomy, 52 months following the initial surgery, signs of local recurrence developed, as well as multiple lymph node and bone metastases. The patient died 75 months following the initial surgery. To the best of our knowledge, this is the first reported case of a lipid cell variant of ureteral UC. The overexpression of HER2 may be associated with both the lipid cell and micropapillary variants of UC.

    The automatic detection and quantification of skeletal structures has a variety of different applications for biological research. Accurate segmentation of the pelvis from X-ray images of mice in a high-throughput project such as the Mouse Genomes Project not only saves time and cost but also helps achieving an unbiased quantitative analysis within the phenotyping pipeline. This paper proposes an automatic solution for pelvis segmentation based on structural and orientation properties of the pelvis in X-ray images. The solution consists of three stages including pre-processing image to extract pelvis area, initial pelvis mask preparation and final pelvis segmentation. Experimental results on a set of 100 X-ray images showed consistent performance of the algorithm. The automated solution overcomes the weaknesses of a manual annotation procedure where intra- and inter-observer variations cannot be avoided.

    The bony pelvis of adult humans exhibits marked sexual dimorphism, which is traditionally interpreted in the framework of the "obstetrical dilemma" hypothesis: Giving birth to large-brained/large-bodied babies requires a wide pelvis, whereas efficient bipedal locomotion requires a narrow pelvis. This hypothesis has been challenged recently on biomechanical, metabolic, and biocultural grounds, so that it remains unclear which factors are responsible for sex-specific differences in adult pelvic morphology. Here we address this issue from a developmental perspective. We use methods of biomedical imaging and geometric morphometrics to analyze changes in pelvic morphology from late fetal stages to adulthood in a known-age/known-sex forensic/clinical sample. Results show that, until puberty, female and male pelves exhibit only moderate sexual dimorphism and follow largely similar developmental trajectories. With the onset of puberty, however, the female trajectory diverges substantially from the common course, resulting in rapid expansion of obstetrically relevant pelvic dimensions up to the age of 25-30 y. From 40 y onward females resume a mode of pelvic development similar to males, resulting in significant reduction of obstetric dimensions. This complex developmental trajectory is likely linked to the pubertal rise and premenopausal fall of estradiol levels and results in the obstetrically most adequate pelvic morphology during the time of maximum female fertility. The evidence that hormones mediate female pelvic development and morphology supports the view that solutions of the obstetrical dilemma depend not only on selection and adaptation but also on developmental plasticity as a response to ecological/nutritional factors during a female's lifetime.

    Recent developments in magnetic resonance (MR) imaging have profoundly changed the investigation of abdominal and pelvic disease in pediatrics. Motion reduction techniques, such periodically rotated overlapping parallel lines with enhanced reconstruction, or PROPELLER, have resulted in reliable imaging with quiet breathing. Faster imaging sequences minimize artifact and allow for more efficient studies. Diffusion-weighted imaging has become increasingly important in the evaluation of neoplastic disease, depicting disease with increased cellularity and helping to differentiate benign from malignant masses. MR enterography helps visualize intra- and extraluminal bowel pathologic conditions. MR cholangiopancreatography can depict congenital and acquired causes of pancreatic and biliary abnormalities. MR urography is an effective technique for a one-stop-shop evaluation of structural urinary tract abnormality and renal function. Three-dimensional acquisitions allow volumetric display of structures from multiple angles. Specialized techniques allow quantification of iron and fat in the viscera in children with hemolytic anemia and obesity, respectively. This article covers current techniques and strategies to perform and optimize MR imaging of the abdomen and pelvis in infants, children, and adolescents and describes important practical applications. © RSNA, 2011.

    Ultrasound technology has evolved dramatically in recent years and now includes applications such as 3-dimensional volume imaging, real-time evaluation of pelvic organs (simultaneous with the physical examination), and Doppler blood flow mapping without the need for contrast, which makes ultrasound imaging unique for imaging the female pelvis. Among the many cross-sectional imaging techniques, we should use the most informative, less invasive, and less expensive modality to avoid radiation when possible. Hence, ultrasound imaging should be the first imaging modality used in women with pelvic symptoms.

    Full Text Available Objective: To evaluate the role of nondismembered laparoscopic pyeloplasty and percutaneous endopyelotomy for ureteropelvic junction obstruction (UPJO with low volume renal pelvis. Material and Methods: Retrospective acquired data of 34 patients of laparoscopic nondismembered pyeloplasty was compared with 26 patients of UPJO with pelvic volume less than 50 ml undergoing antegrade endopyelotomy and analyzed for clinical parameters, operative outcomes and success of procedures. All patients were followed up clinically and with diuretic renogram at regular intervals. Results: Mean age, renal pelvic volume and preoperative glomerular filtration rate (GFR was 25 years, 43.6 ml and 42.5 ml/min, respectively in endopyelotomy group and 21 years, 34.4 ml and 39.9 ml/min, respectively in laparoscopic pyeloplasty group. Mean operative time, postoperative analgesic requirement and mean hospital stay was 100min, 250 mg and 4 days, respectively in endopyelotomy group and 210 min, 300 mg and 4 days, respectively in laparoscopic pyeloplasty group. Only operative time was significantly different between two groups (P < 0.05. Mean follow-up was 36 and 39 months and success rates were 91.2% and 88.8% in laparoscopy and endopyelotomy group, respectively (P < 0.05. No significant complication was seen in endopyelotomy group while two patients had hematuria (one requiring blood transfusion and three had increased drain output for more than 3 days in laparoscopy group. Conclusion: Percutaneous endopyelotomy is associated with significantly less operative time and postoperative complication rate and provides equivalent success in comparison to nondismembered laparoscopic pyeloplasty in patients with UPJO and low volume pelvis. It can be a preferred minimally invasive treatment modality for such patients.

    Twenty patients free from urodynamic disturbances and 26 patients presenting with nephritic colic were studied in an ultrasound investigation into the urinary system and renal arteries. The examinees divided into the following groups: controls, patients with acutely congestive kidney, patients with calculi in the ureter without manifest obstruction, and patients with renal calculi. There were three pregnant women in the above series. Patients with acutely congestive kidney demonstrated significant elevation (P < 0.05) of PI, IR, S/D, and decrement of Vmin by comparison with controls. The results obtained with Doppler Ultrasound (DU) formed the basis for catheterization of the ureter in 1 pregnant female examinee, for endovesical ureterolithoextraction in 1 patient, with three others having had their calculi reduced to fine particles. Employment of DU to study renal arteries in patients presenting with disordered urodynamics of the upper urinary tract is helpful when choosing between therapeutic policies to be adopted, with particular emphasis being given to the management of pregnant female patients.

    Ultrasonography (US), radiography of the kidneys, ureters and bladder (RKUB), intravenous urography (IVU) and especially non-enchanced CT are well established diagnostic modalities in screening patients with urolithiasis, while not always fully diagnostic especially when obstructive uropathy or calculous pyelonephritis are present . Diuretic renal scintigraphy (DRS) can determine obstruction, may differentiate between complete or partial, acute or chronic obstruction, but can not specify the cause and often the location of obstruction. The imaging protocol, including DRS with technetium-99m-mercaptylacetyltriglycine ((99m)Tc-MAG3) and single photon emission tomography/computed tomography (SPET/CT) of the kidneys, ureters, and urinary bladder allows for both functional and morphological information, visualization of renal stones and possible renal complications. The main advantages and limitations of this combined examination are discussed and the test is compared to the separate use of DRS and low dose of CT, in urolithiasis.

    Full Text Available Chronic renal insufficiency is a functional definition which is characterized by irreversible and progressive decreasing in renal functions. This impairment is in collaboration with glomeruler filtration rate and serum creatinine levels. Besides this, different grades of bone metabolism disorders develop in chronic renal insufficiency. Pathologic changes in bone tissue due to loss of renal paranchyme is interrelated with calcium, phosphorus vitamine-D and parathyroid hormone. Clinically we can see high turnover bone disease, low turnover bone disease, osteomalacia, osteosclerosis and osteoporosis in renal osteodystropy. In this article we aimed to review pathology of bone metabolism disorders due to chronic renal insufficiency, clinic aspects and treatment approaches briefly.

    Evaluation of the fractured pelvis or acetabulum requires both standard radiographic evaluation as well as computed tomography (CT) imaging. The standard anterior-posterior (AP), Judet, and inlet and outlet views can now be simulated using data acquired during CT, decreasing patient discomfort, radiation exposure, and cost to the healthcare system. The purpose of this study is to compare the image quality of conventional radiographic views of the traumatized pelvis to virtual radiographs created from pelvic CT scans. Five patients with acetabular fractures and ten patients with pelvic ring injuries were identified using the orthopedic trauma database at our institution. These fractures were evaluated with both conventional radiographs as well as virtual radiographs generated from a CT scan. A web-based survey was created to query overall image quality and visibility of relevant anatomic structures. This survey was then administered to members of the Orthopaedic Trauma Association (OTA). Ninety-seven surgeons completed the acetabular fracture survey and 87 completed the pelvic fracture survey. Overall image quality was judged to be statistically superior for the virtual as compared to conventional images for acetabular fractures (3.15 vs. 2.98, p = 0.02), as well as pelvic ring injuries (2.21 vs. 1.45, p = 0.0001). Visibility ratings for each anatomic landmark were statistically superior with virtual images as well. Virtual radiographs of pelvic and acetabular fractures offer superior image quality, improved comfort, decreased radiation exposure, and a more cost-effective alternative to conventional radiographs.

Her past medical history indicated that 2 years earlier she had undergone enucleation of her left eye for a primary choroidal melanoma. Imaging studies revealed a osteolytic destruction with soft tissue mass involving the right hemipelvis (zone I–II. Single-photon emission computed tomography (SPECT and positron emission tomography–computed tomography (PET–CT showed no other sites of metastases. Consequently, the patient underwent hemipelvic prosthesis reconstruction after tumor resection. Postoperative pathological diagnosis was metastatic malignant melanoma. Thirty months after treatment, imaging studies indicated no evidence of recurrence, and functional recovery was excellent. To our knowledge, the literature does not reveal any previously reported cases of ocular choroidal melanoma that metastasized to pelvis, meanwhile was carried out hemipelvic prosthesis reconstruction after pelvic tumor resection.

  2. Lymphocele – urological complication after renal transplantation

    Full Text Available Renal transplantation is the best renal replacement treatment. It provides longer survival and a better quality of life. The outcome of renal transplantation is influenced by the occurrence of various complications, including urological. One of the most frequently occurring complicationsis lymphocele. Most cases of lymphocele develop during a period of several weeks after the procedure of transplantation. However, there are some literature reports concerning lymphocele diagnosis in the later period, even after several years. Most cases of lymphocele are asymptomatic and are diagnosed accidentally. Nevertheless, a large lymphocele may press the kidney, ureter, urinary bladder or neighbouring blood vessels, causing deterioration of renal function, leg oedema and thrombosis of iliac vessels. Among other complications there are infections. The cause of lymphocele is collection of the lymph drained from damaged lymph vessels surrounding iliac blood vessels and/or lymph vessels of the graft. Important factors predisposing to lymphocele are immunosuppressive treatment, including mTOR inhibitors, mycophenolic acid derivatives and high doses of glucosteroids. Factors favouring occurrence of lymphocele comprise obesity, diabetes, elderly age of recipient, long time of warm ischaemia, acute rejection episodes and delayed graft function. The authors describe presently available treatment methods including aspiration and percutaneous drainage, with or without sclerotisation, drainage using the Tenckhoff catheter and laparoscopic or open fenestration. At present, laparoscopic fenestration is considered to be the most efficient and the safest method. However, there are clinical cases where open surgical treatment is necessary.

Early diagnosis using scintigraphy with technetium-99m-labeled dimercaptosuccinic acid (DMSA scan and early treatment may decrease or prevent development of renal parenchymal lesions. The aim of this study was to assess the occurrence of renal parenchymal lesion in children admitted with a first-time symptomatic UTI and to evaluate the relation between renal parenchymal damage and severity of vesicoureteral reflux (VUR. A total of 102 children with first time acute pyelonephritis (APN were enrolled in the study. All children studied with DMSA scan and ultrasonography (US. Voiding cystourethrography (VCUG was performed in 98 children when urine culture became negative. Changes on the DMSA scan and US were found in 178 (88% and 5 (2.4% out of 203 renal units during the acute phase, respectively. All abnormal renal units on US showed severe parenchymal involvement on DMSA. We also found significant correlation between severity of VUR and abnormal US results on kidneys. Of 40 kidneys with reflux, 38 (95% were found to have abnormal renal scan. Among 155 kidneys with non-refluxing ureters 132 (85.2% revealed parenchymal changes on renal cortical scintigraphy. Kidneys with moderate to severe reflux were more likely to have severe renal involvement. We found a high incidence of renal parenchymal changes in children with APN. Additionally, renal involvement was significantly higher in children with moderate to severe reflux. When there are high-grade VUR and female gender, the risk of renal parenchymal involvement is higher.

    A case of sarcomatoid collecting duct carcinoma (CDC) of kidney is presented, in which the diagnosis was made cytologically with voided urine and renal pelvis lavage. Cytology of hemorrhagic voided urine revealed highly atypical adenocarcinoma cells with reminiscent ductal structure, which suggested CDC as the most likely diagnosis. Computed tomography and magnetic resonance imaging demonstrated a left renal tumor, and selective lavage of left renal pelvis yielded spindle-shaped, highly atypical cells that indicated sarcomatoid carcinoma. The diagnosis of renal cancer with urine cytology is challenging because of small number of tumor cells in the urine, which are often associated with degeneration. As the urinary cytologic findings of sarcomatoid CDC have not been reported, the characteristic cytologic findings of sarcomatoid CDC are described in detail, and the differential diagnoses with diagnostic pitfalls were discussed.

    Acute renal infarction is a rare disease and it is often difficult to make a clinical diagnosis due to the non-specific clinical presentations and lack of the physicians' awarenesses. We experienced a case of a 72-year-old man who was diagnosed as multiorgan with renal infarction during the bridge therapy of cerebral infarction with atrial fibrillation. Computed tomogram (CT) with intravenous contrast of the abdomen and pelvis revealed left renal infarction with renal artery occlusion, multifocal splenic infarction, and ischemic colitis on rectum and sigmoid colon. The patient was treated with low molecular weight heparin for 10 days, his symptoms were improved and laboratory findings were normalized. Follow-up CT was performed on the 43th day, there were persisted left renal infarction with atrophic change shown and the splenic perfusion was improved.

Pathogenesis of postradiation lesions of the ureteral wall are explained by destructive effects of radiation on the basal membranes of the capillary cell, causing an occlusion, thrombosis, and neovascularization, which in turn leads to proliferation of fibroblasts and stromal fibrosis. Possible complications include hematuria, urinary tract infections, vesicoureteral reflux, stent migration, stent encrustation. By the way, presence of the stent is often associated with pain and discomfort in patients. Aim of this work is to improve the results of treatment of strictures of the lower ureter following radiotherapy, by evaluating effectiveness of extravesical uretherocystoanastomosis and Boari procedure.

    The subserous space is a large, anatomically continuous potential space that interconnects the chest, abdomen, and pelvis. The subserous space is formed from areolar and adipose tissue, and contains branches of the vascular, lymphatic, and nervous systems. As such, it provides one large continuous space in which many disease processes can spread between the chest, abdomen, and the pelvis.

    Near infrared fluorescence imaging is a promising technique that offers real-time visual information during surgery. In this study we report the first clinical results to our knowledge of ureteral imaging using near infrared fluorescence after a simple peripheral infusion of methylene blue. Furthermore, we assessed the optimal timing and dose of methylene blue. A total of 12 patients who underwent lower abdominal surgery were included in this prospective feasibility study. Near infrared fluorescence imaging was performed using the Mini-FLARE™ imaging system. To determine optimal timing and dose, methylene blue was injected intravenously at doses of 0.25, 0.5 or 1 mg/kg after exposure of the ureters. Imaging was performed for up to 60 minutes after injection. In all patients both ureters could be clearly visualized within 10 minutes after infusion of methylene blue. The signal lasted at least up to 60 minutes after injection. The mean signal-to-background ratio of the ureter was 2.27 ± 1.22 (4), 2.61 ± 1.88 (4) and 3.58 ± 3.36 (4) for the 0.25, 0.5 and 1 mg/kg groups, respectively. A mixed model analysis was used to compare signal-to-background ratios among dose groups and times, and to assess the relationship between dose and time.

    Full Text Available This report illustrates the case of a patient who suffered an iatrogenic complete injury of both ureters after a complex surgical procedure to remove a large sacral chordoma. Ureteral recanalization was achieved with two removable, autoexpandable, and polytetrafluoroethylene covered nitinol stents. To our knowledge, we describe the first application of this type of stents to treat a bilateral ureteral transection. Despite the bad general conditions of the patient, the ureteral stents successfully restored and maintained the bilateral ureteral continuity.

    It has been well known that complex tasks such as walking and arm reaching can be achieved by the coordination of the trunk and pelvis. However, understanding of the effect of aging on the coordination of the trunk and pelvis during axial trunk rotation is still lacking. The present study examined relative phase of the trunk and pelvis during axial trunk rotation, and compared it between young and older groups. 22 healthy young (age: 23.9±4.6, gender: 11 male and 11 female) and 22 healthy elderly (age: 68.4±4.9, gender: 11 male and 11 female) individuals participated in the experiment and performed axial trunk rotation. Relative phase between the trunk and pelvis was calculated based on the angular displacements of the two segments. The results demonstrated age-related changes in coordination pattern of the trunk and pelvis during axial trunk rotation.

    The aim of investigation is improvement of treatment results of unstable injuries in the pelvic ring in patients with severe associated injuries. An experience of treatment of 533 patients with unstable pelvic injuries is presented. Diagnostic measures take into account the severity of the condition of the victim. Stage treatment with consecutive performing of temporary external immobilization of the pelvis and following final osteosynthesis was optimal. Replacement of external fixation for submersible osteosynthesis held in stable or terminal condition of the victim. Developed treatment of patients with pelvic injuries decreased mortality to 8.4%, number of general complications to 11.6% and number of local complications to 8.7%. Also it decreased length of hospital stay to 35.5 days and provided excellent and good functional results of treatment in 78.9% of cases.

    Solitary fibrous tumors (SFT) are rare spindle cell neoplasms. To date only very few cases of pelvic SFT have been reported in the literature. SFT are characterized by unique microscopic and immunohistochemical findings. Complete local resection is the treatment of choice. Recurrence and metastasis may be related to infrequent malignant histological features, but histology is not always a reliable predictor for prognosis. Therefore long-term follow-up is necessary.We report about a male patient with a malignant pelvic SFT. After complete resection the tumor recurred after a short period of 6 months posterior to the original location in the pelvis. The differential diagnoses and the therapy options are discussed with a review of the present literature.

    Intraluminal optical coherence tomography (OCT) applies coherent light to provide cross-sectional images with a spatial resolution of 10-25 {mu}m. We compared OCT and matching whole-mount histology microscopy sections of porcine upper ureters ex vivo for visualization and delineation of different tissue layers of the ureteral wall. Porcine ureters (six specimens, 24 quadrants) were flushed with normal saline solution prior to insertion of the OCT catheter (diameter, 0.014 inch, OCT wavelength, 1,300{+-}20 nm). Cross-sectional OCT images were obtained in marked locations before specimens were fixed in 4% formalin, cut at marked locations, whole-mounted, and stained with hematoxilin and eosin. Visualization and delineation of different tissue layers of the ureteral wall by OCT was compared with matching histology by two independent observers (O1,O2). OCT distinguished tissue layers of the ureteral wall in all quadrants. In OCT images, O1/O2 delineated urothelium and lamina propria in 23/24 quadrants, lamina propria and muscle layer in 19/16 quadrants, inner and outer muscle layer in 13/0 quadrants, and urothelial cell layers in 13/2 quadrants, respectively. Intraluminal OCT provides histology-like images of the ureter in porcine specimens ex vivo and reliably distinguishes between urothelium and deeper tissue layers of the ureteral wall. (orig.)

    The case is described of a 53-year old woman who had given birth three times and had undergone one abortion. After she was treated as an outpatient because of back pain in the lower waist area suppuration occurred from a fistula laterally right to the sacral bone in the area of the buttocks triangle, which persisted even after several outpatient surgical interventions. In addition, she had experienced a weight loss of 24 kg. At admission she had a temperature of 39 degrees Celsius, anemia, and leukocytosis. Sonography indicated slight hepatomegaly, hydroureter, right-sided hydronephrosis, and an right ovarian cyst of 4 cm size. Computer tomography showed a blurry structure that extended from the right kidney pole along the M. iliopsoas caudally up to the small pelvis, pressing against the organs caudally-ventrally, which also broke through dorsally between the lumbar region vertebrae and pelvis in the gluteal region percutaneously. The process was categorized as a frank paranephritis prolapsus abscess. Cessation of urine was determined. Laparotomy was carried out because of the suspicion of an inflammatory adnexal disease with parametritis. The uterus, including both adnexa as well as the conglomeration tumor, were removed. In the uterine cavity a Dana Cor IUD was found that had been inserted 13 years before and forgotten by the patient. At the site of the right adnexum there was a tumor (9 x 6 x 5 cu. cm) as well as a tube changed by inflammation (7 x 1.5 sq. cm). On the right side there was unspecific, suppurative salpingitis and in the ovary an abscess formation on the grounds of actinomycosis. On the left side there was only a suppurative inflammation of the tube without actinomycosis sediment. Immediately a high-dose antibiotic therapy (Penicillin G, 10 million IU) was started, lasting for 1 year. The kidney cessation with the back complaints rapidly disappeared. The cutaneous fistulae healed with scarring, however, a fully normal right-sided kidney function

    Thorax and pelvis motion during the golf swing have most frequently been described for male golfers at discrete points during the swing, such as top of backswing (TBS) and ball contact (BC). Less is known about the continual motion and coordination of the thorax and pelvis throughout the downswing for either male or female golfers. The purpose of this study was to present detailed 3D kinematic profiles of thorax and pelvis motion during the downswing, and to determine if differences in kinematics exist between male and female skilled golfers. Thorax and pelvis data were collected from 19 male (26+/-7 years) and 19 female (25+/-7 years) skilled golfers (handicap thorax-pelvis separation angles. At BC males had greater pelvis posterior tilt, greater pelvis and thorax lateral tilt to the right, and less pelvis and thorax axial rotation to the left compared to females. Males achieved greater peak thorax and pelvis angular velocity, and angular velocity at BC, in the anterior-posterior and lateral tilt directions. Phase plane trajectories revealed that males and females had similar thorax lateral tilt and anterior-posterior tilt angular velocity-displacement relationships at TBS, yet by BC males had greater tilt angles and velocities compared to females. Collectively, the results suggest that male and female skilled golfers have different kinematics for thorax and pelvis motion, predominantly for lateral and anterior-posterior tilt. What might be considered optimal swing characteristics for male golfers should not be generalized to female golfers. Copyright 2010 Elsevier Ltd. All rights reserved.

  1. Particle motion in unsteady two-dimensional peristaltic flow with application to the ureter

    Particle motion in an unsteady peristaltic fluid flow is analyzed. The fluid is incompressible and Newtonian in a two-dimensional planar geometry. A perturbation method based on a small ratio of wave height to wavelength is used to obtain a closed-form solution for the fluid velocity field. This analytical solution is used in conjunction with an equation of motion for a small rigid sphere in nonuniform flow taking Stokes drag, virtual mass, Faxén, Basset, and gravity forces into account. Fluid streamlines and velocity profiles are calculated. Theoretical values for pumping rates are compared with available experimental data. An application to ureteral peristaltic flow is considered since fluid flow in the ureter is sometimes accompanied by particles such as stones or bacteriuria. Particle trajectories for parameters that correspond to calcium oxalates for calculosis and Escherichia coli type for bacteria are analyzed. The findings show that retrograde or reflux motion of the particles is possible and bacterial transport can occur in the upper urinary tract when there is a partial occlusion of the wave. Dilute particle mixing is also investigated, and it is found that some of the particles participate in the formation of a recirculating bolus, and some of them are delayed in transit and eventually reach the walls. This can explain the failure of clearing residuals from the upper urinary tract calculi after successful extracorporeal shock wave lithotripsy. The results may also be relevant to the transport of other physiological fluids and industrial applications in which peristaltic pumping is used.

    The present study comprises of 10 dogs of either sex with primary indication of azotaemia. All the dogs were subjected to detailed clinical, haematobiochemical, urinalysis, and microbiological examination along with radiographical and ultrasonographical examination. Based on the ultrasonographic structural abnormalities, the different renal affections associated with CRF in majority of dogs were diagnosed. The different affections included "end-stage" kidneys (n = 4), hydronephrosis (n = 1), renomegaly (n = 1), nephritis (n = 1), nephrolithiasis (n = 1), nephrocalcinosis (n = 1), and renal cyst (n = 1). The significant ultrasonographic features in these affections included small kidneys with loss of corticomedullary demarcation ("end-stage" kidneys); increased cortical echogenicity (nephritis); dilation of the renal pelvis, separation of the central renal sinus with anechoic space, atrophy of renal medulla, (hydronephrosis); enlarged kidneys with increased overall echogenicity of renal cortex (renomegaly and associated nephritis); hyperechoic-mineralized structure with shadowing (nephrolithiasis); diffuse, small, multiple hyperechoic structures in the renal parenchyma with distal acoustic shadowing (nephrocalcinosis); small spherical intercortical anechoic structures fluid (renal cysts). In the present study, ultrasound proved to be a quick, convenient, and sensitive modality in detecting alterations in renal size and parenchymal architecture. All the dogs so diagnosed with CRF were rendered conservative medical treatment to control clinical signs of uraemia; maintain adequate fluid, electrolyte, and acid/base balance; provide adequate nutrition; minimize progression of renal failure.

    Full Text Available Retroperitoneal schwannomas are extremely rare, and unreported in Urology. Often thought to be malignant from imaging the diagnosis is often delayed until Histology. We report a case of retroperitoneal schwanoma thought to be a malignant renal mass. Seventy three year old lady presented with abdominal pain. Imaging showed a mass attached to the renal pelvis thus she underwent a radical nephrectomy. Histology reported retroperitoneal schwannoma. Malignant forms are rare however treatment for these is surgical excision. Awareness of the existence of these tumors may help in avoiding unnecessary radical surgeries by opting for biopsy preoperatively.

    The purpose of this study was to investigate the interrelationship between the thorax and pelvis during coupled movement patterns. Fifty-seven participants were assessed using an infrared motion analysis system to track trunk movement during maximal pelvis and thorax rotations over four trunk inclinations and two pelvic constraint conditions. A repeated-measures multivariate analysis of variance investigated the effects of forward trunk inclination and pelvic constraint on thorax and pelvic rotation. Forward trunk inclination from neutral to 45° resulted in a 46% (p thorax rotation with an unconstrained pelvis. A constrained pelvis resulted in a 15% (p thorax rotation. An externally constrained pelvis allowed the thorax to achieve an average of 18° (SD = 2°) greater rotational range of motion across all angles. This study reinforced the importance of allowing the pelvis to rotate during whole body axial rotation tasks. Results indicated that maximum axial trunk rotation is best achieved in a neutral posture, when the pelvis is allowed to contribute and flexion at the hips should be minimised. For example, if a recumbent task requires rotation of the torso, then the chair seat should be allowed to swivel.

    We determined the angular range of motion and the relative timing of displacement in the thorax, lumbar spine, and pelvis in the transverse plane during treadmill walking at three velocities. Nine healthy young females walked on a treadmill for three minutes at 0.40, 0.93, and 1.47 m/s. The position of seven reflective markers and three rigs placed on the thorax, lumbar spine, and pelvis were recorded at 200 Hz by an eight-camera motion capture system. As gait velocity increased, stride length increased, cycle time decreased, and angular displacement in the thorax and L1 decreased but increased at the pelvis and L5 (all P thorax (P thorax and L1 and L3 were in-phase for shorter duration as gait velocity increased, and this reduction was especially large, approx. 32% (P thorax and pelvis. As gait velocity increased, the pelvis rotated earlier, causing the shortening of in-phase duration between thorax and pelvis. These data suggest that, as gait velocity increases, pelvis rotation dictates trunk rotation in the transverse plane during gait in healthy young females.

    Transverse plane pelvis rotations during walking may be regarded as the "first determinant of gait". This would assume that pelvis rotations increase step length, and thereby reduce the vertical movements of the centre of mass-"the pelvic step". We analysed the pelvic step using 20 healthy young male subjects, walking on a treadmill at 1-5 km/h, with normal or big steps. Step length, pelvis rotation amplitude, leg-pelvis relative phase, and the contribution of pelvis rotation to step length were calculated. When speed increased in normal walking, pelvis rotation changed from more out-of-phase to in-phase with the upper leg. Consequently, the contribution of pelvis rotation to step length was negative at lower speeds, switching to positive at 3 km/h. With big steps, leg and pelvis were more in-phase, and the contribution of pelvis rotation to step length was always positive, and relatively large. Still, the overall contribution of pelvis rotations to step length was small, less than 3%. Regression analysis revealed that leg-pelvis relative phase predicted about 60% of the variance of this contribution. The results of the present study suggest that, during normal slow walking, pelvis rotations increase, rather than decrease, the vertical movements of the centre of mass. With large steps, this does not happen, because leg and pelvis are in-phase at all speeds. Finally, it has been suggested that patients with hip flexion limitation may use larger pelvis rotations to increase step length. This, however, may only work as long as the pelvis rotates in-phase with the leg.

    Postoperative complications after renal transplantation, such as hematomas, abscesses, urinomas and lymphoceles and obstruction of the ureter, can be diagnosed by means of ultra sonography. Early vascular complications, such as venous thrombosis and arterial occlusion or stenosis, can be recognized by duplex ultrasonography and accurately depicted by angiography to allow planning of surgical intervention. Stenosis of the renal artery is amenable to treatment by percutaneous angioplasty. Parenchymatous complications (acute tubular necrosis, acute rejection, cyclosporin-Atoxicity) can cause changes in the intrarenal flow patterns at duplex ultra sonography, but this examination does not allow accurate diagnosis and differentiation of these changes. Magnetic resonance imaging is a very promising method for the differential diagnosis of parenchymatous complications. (orig.) .

    Full Text Available Renal cryoablation is an alternative minimally-invasive method of treatment for localized renal cell carcinoma. The main advantages of this methodology include visualization of the tumor and the forming of "ice ball" in real time, fewer complications compared with other methods of treatment of renal cell carcinoma, as well as the possibility of conducting cryotherapy in patients with concomitant pathology. Compared with other ablative technologies cryoablation has a low rate of repeat sessions and good intermediate oncological results. The studies of long-term oncological and functional results of renal cryoablation are presently under way.

    2003-12-01

    The more extensive a surgical procedure in a small pelvis, the higher the risk for the lower urinary tract with its nerve supply and nerve plexus. This concerns mainly the sympathetic chains, the parasympathetic structures and, rarely, the visceral supply of the pelvic floor. Direct trauma to the bladder and its vascular supply as well as indirect injury by displacement of the bladder need to be seriously considered. Problems with micturition and impaired storage capacity of the bladder are the result. Complete urodynamic examination and follow-up can help in differentiating between temporary and persisting disturbances and in taking therapeutical decisions. The most evident postoperative complication is disturbed micturition, managed initially by suprapubic urinary diversion, followed as soon as possible by intermittent self-catheterisation. This is the only way to avoid overstretching of the bladder, recurring urinary tract infection and damage to the upper urinary tract. Restoration of spontaneous micturition can be supported by drug treatment with parasympatholytics and/or alpha-blockers if the measured bladder pressure and residual urine are within tolerable limits. For electrostimulation of micturition, intravesical therapy, although timeconsuming, is best suited because it can easily be done on an outpatient basis. More promising seems bilateral sacral neuromodulation, which, however, is a rather complicated and expensive procedure. Surgical procedures to reduce the voiding resistance of the bladder involve the risk of postoperative incontinence because the sphincter function in those patients is often disturbed too. Persisting problems with bladder storage capacity as a result of tumor surgery in the small pelvis are frequently secondary to retention of urine (overflow incontinence). In these cases, regular evacuation of the bladder by intermittent self-catheterisation can lead to social acceptance. Reduced bladder compliance and lowering of the urethral

    Full Text Available Objective To evaluate ureteroscopy (URS outcomes and management of perforations in impacted ureteral stones. Materials and Methods We retrospectively evaluated data from 81 patients who had undergone URS for impacted ureteral stones. Per-operative complications were evaluated visually and retrograde ureterography was performed when needed. Injuries of less than 50% around the ureter were classified as minor perforation and greater levels, as major perforation. Perforations were treated by double-j stent or a primary repair with consideration of the perforation grade. Results The stone-free rate was 69% on the first URS attempt and 79% at the end of 3 months. Complications occurred in 34 (42% patients. Minor perforation occurred in five patients and only double-j insertion was performed at the end of the procedure. Permanent ureteral stricture occurred in four of five patients. Three patients were treated by open ureterolithotomy, fibrotic segment resection and ureteroureterostomy due to major perforations. Transient or permanent ureteral stricture occurred in none of the three patients. The stricture rate was significantly higher in patients who were treated with double-j stent (80% vs. 0% p=0.028 although they had lower perforation rate. Upper location, bigger size (>10 mm of the ureteral stones and not using smash and go strategy were found to be significant predictors of complications. Conclusion URS for impacted ureteral stone has low success and high complication rates, especially for proximal and big stones. The conservative treatment may fail and result in stricture when perforation is present. Therefore, perforation treatment must be done by fibrotic segment excision and ureteroureterostomy.

    Full Text Available ABSTRACT: The renal vasculature was always a subject of varia tions both in the number and pattern of portal of entry into kidney and Perihilar placement of the artery, vein and pelvis. Good anatomical insight is an essential prerequisite besides the surgical expertise. The cadaveric dissection revealed a Right Kidney supplied by Quadruple renal arteries & Drained by two renal veins. The main renal artery (MRA was arising from antero lateral aspect and the accessory renal artery was arising from anterior as pect of aorta 1cm distal to the former vessel. Only the MRA showed Fork Pattern Branching with fou r anterior segmental arteries and one posterior segmental artery in the pre hilar region. T he first and fourth segmental arteries showed a small subsidiary branch and a large tortuo us subsidiary branch respectively. The later along with the branch running downwards and lateral from lower renal artery formed a common trunk and pierced the capsule and entered int o the substance of the kidney anteriorly about 2cm lateral to the hilum, thus forming an abe rrant artery. The upper polar artery was seen arising from the lower supra renal artery. The main renal vein (MRV, was formed by two formative tributaries of which one is larger and ot her being smaller. The later was seen just anterior to the third anterior segmental branch of MRA. Accessory renal vein was formed by only one tributary encircled by the fourth anterior segmental artery and posterior segmental artery. There was crowding of structures seen with altered hilar anatomy in both vertical and horizontal disposition. Such a rare combination of extra renal multiple arterio-venous variation is of worth concern to the urologists harvesting ki dneys from the live donors for performing transplantation procedures. Partial nephrectomies for the hilar tumors and for Radiologists during interpretation of the angiograms.

    This paper reports on the association between renal sinus hyperechogenicity and acute pyelonephritis. The medical records and imaging studies of 18 children displaying this pattern were retrospectively studied. Thickening of the renal pelvis and renal enlargement were the most frequent associated sonographic abnormalities. Further subtle findings can be found on sonography and colour/power Doppler. Their identification can help in the diagnostic approach to acute pyelonephritis and may obviate the need for other imaging modalities such as enhanced CT or {sup 99} {sup m}Tc-DMSA scintigraphy. Renal sinus hyperechogenicity was also identified in a parallel study performed in female rabbits with experimental pyelonephritis and was shown, histologically, to be related to exudates of fibrin and polymorphonuclear leukocytes, interstitial oedema and micro-abscesses.

    Magnetic resonance (MR) imaging of the abdomen and pelvis can be limited for assessment of different conditions when imaging inadequately distended hollow organs. Endoluminal contrast agents may provide improved anatomic definition and detection of subtle pathology in such scenarios. The available routes of administration for endoluminal contrast agents include oral, endorectal, endovaginal, intravesicular, and through non-physiologic accesses. Appropriate use of endoluminal contrast agents requires a thorough understanding of the clinical indications, available contrast agents, patient preparation, and interaction of the contrast agent with the desired MR imaging protocol. For example, biphasic oral enteric contrast agents are preferred in MR enterography as their signal properties on T1- and T2-weighted imaging allow for evaluation of both intraluminal and bowel wall pathology. In specific situations such as with MR enterography, MR defecography, and accurate local staging of certain pelvic tumors, the use of an endoluminal contrast agent is imperative in providing adequate diagnostic imaging. In other clinical scenarios, the use of an endoluminal contrast agent may serve as an indispensable problem-solving tool.

    AIMS: To report the magnetic resonance imaging (MRI) findings of osteomalacic insufficiency fractures of the pelvis. MATERIALS AND METHODS: In all, 12 persons presenting with chronic pelvic pain and with a definitive diagnosis of osteomalacia (OM) were enrolled in this study. Radiological work-up included direct radiographs (n=12), computed tomography (n=5), scintigraphy n=12) and MRI (n=12). The location of the insufficiency fractures and corresponding MRI appearances were evaluated. Depending on the presence or absence of signal intensity around the fractures, the lesions were grouped into active and chronic forms. RESULTS: A total of 34 insufficiency fractures were depicted on imaging studies. MRI demonstrated 33 of the lesions. All the insufficiency fractures were seen as a hypointense lines or fissures on T1- and T2-weighted and STIR MR images. There was a high frequency of insufficiency fractures at the sacrum and iliac bone (16/34, 47%). Overall, 11 chronic-type (no abnormal signal intensity around the fissure) and 22 active-type (abnormal signal intensity around the fissure) insufficiency fractures were detected by MRI. Follow-up MR examinations of 2 subjects showed that abnormal signal intensity had disappeared after appropriate treatment. CONCLUSION: The results of this study showed that the iliac and sacral bones are frequently involved in patients with OM. MRI can determine the clinical activity of the disease, and can monitor the response to treatment of the active type of insufficiency fractures.

    Full Text Available Introduction. Crossed renal ectopia with fusion is a very rare congenital anomaly and the reported incidence varies between 1:1000 and 1:7000. The kidney is located on the opposite site of the mid- line from where the ureter enters the bladder. Eighty-five percent of crossed renal ectopia kid- neys are fused from below to the normally located kidney. This anomaly is more frequent for left kidney and it’s associated with vesico-ureteral re- flux (VUR in 25-70% of cases. We report the management of a six-years-old patient with Pluri- malformative Syndrome, trisomy p16 and mono- somy q2, crossed renal ectopia with fusion type A and bilateral vesico-ureteral reflux (grade IV in the right kidney and grade III in the left.Materials and Methods. A 6-year-old boy was ammitted to our hospital for UTI in plurimalfor- mative syndrome characterized at birth by cleft palate, macrocephaly, congenital clubfeet, twisted right arm, congenital dysplasia of the hip, balanic hypospadias, bilateral inguinal hernia, right renal agenesis and epilepsy tonic-clonic. MRI revealed a fusion of the ectopic kidney with the left ortho- topic kidney (crossed renal ectopia with fusion type A. Voiding cystography showed a dilatated ureter of the crossed ectopic kidney passing across the midline and of the left ureter, and a bilateral vesico-ureteral reflux ( grade IV VUR in the right kidney and grade III VUR in the left. For this reason bilaterally endoscopic subureteral infiltra- tion was performed with Deflux ( 0.3 cc for side. Results. Patient was discharged in third day and he took antibiotic for one week. There weren’t complications like fever, obstruction or UTI. Fol- low-up after 1 month is normal and there weren’t UTI. Conclusion. Generally the outcome of patients with fused crossed renal ectopia is good. Presence of associated pathology likeVUR, could lead to a progressive deterioration of renal function.

    A 55-year-old man had a five-day history of 'pins and needles' sensation on the left chin. Examination showed decreased pinprick sensation on the territory of the left mandibular branch of the trigeminal nerve. Brain magnetic resonance imaging (MRI) with gadolinium showed enhancement involving the left mandibular branch. Computed tomography (CT) of the chest, abdomen, and pelvis showed a left kidney mass diagnosed as renal carcinoma following nephrectomy. The 'numb-chin' syndrome heralds or accompanies systemic malignancies. Trigeminal perineural spread has been well-documented in head and neck neoplasms, however, to our knowledge, it has not been reported in renal neoplasms. (author)

    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

  1. THE EFFECT OF HYPOXIA ON ELECTRICAL AND CONTRACTILE PROPERTIES OF SMOOTH MUSCLES OF THE GUINEA PIG URETER

    Full Text Available Aim. The effect of hypoxia on the electrical and contractile activities of smooth muscles cells (SMCs of the guinea pig ureter was studied by the method of the double sucrose bridge.Materials and methods. This method allows registering simultaneously parameters of the action potential (AP and the contraction of SMCs, caused by an electrical stimulus.Results. It was found that lowering the oxygen content in the perfusion solution for 10 min resulted to an increase of electrical and contractile activity of ureteral SMCs. Addition of tetraethylammonium chloride (TEA, 5 mM – nonselective blocker of potassium membrane conductance – in hypoxic conditions causing an additional increase in the amplitude of the AP, duration of the AP plateau and the contractile responses of smooth muscles. Thus, the hypoxia decreased the potassium membrane conductance of ureteral SMCs. Inhibition of the effect of the α1 -adrenergic receptors agonist phenylephrine (PE, 10 mM on the electrical and contractile properties of SMCs in hypoxic condition indicate the involvement of the protein kinase C-dependent signaling system in effects of hypoxia. Pretreatment of ureteral smooth muscles with bumetanide (100 mM – selective inhibitor of Na+,K+,2Cl- - cotransporter (NKCC – caused a decrease of the activating effect of hypoxia on the SMCs of guinea pig ureter.Conclusion.Thus, the impact of hypoxia on the regulation of electrical activity and contractions of smooth muscles of guinea pig ureter may be due to changes in ion permeability of membranes SMCs and operation of ion-transporting systems.

    Patients with non-specific low back pain, or a similar disorder, may stiffen their trunk, which probably alters their walking coordination. To study the direct effects of increasing trunk stiffness, we experimentally increased trunk stiffness during walking, and compared the results with what is known from the literature about gait coordination with, e.g., low back pain. Healthy subjects walked on a treadmill at 3 speeds (0.5, 1.0 and 1.5m/s), in three conditions (normal, while contracting their abdominal muscles, or wearing an orthopedic brace that limits trunk motions). Kinematics of the legs, thorax and pelvis were recorded, and relative Fourier phases and amplitudes of segment motions were calculated. Increasing trunk stiffness led to a lower thorax-pelvis relative phase, with both a decrease in thorax-leg relative phase, and an increase in pelvis-leg relative phase, as well as reduced rotational amplitude of thorax relative to pelvis. While lower thorax-pelvis relative phase was also found in patients with low back pain, higher pelvis-leg relative phase has never been reported in patients with low back pain or related disorders. These results suggest that increasing trunk stiffness in healthy subjects causes short-term gait coordination changes which are different from those seen in patients with back pain.

    The aim of this study was to compare trunk muscular recruitment and lumbar spine kinematics when motion was constrained to either the thorax or the pelvis. Nine healthy women performed four upright standing planar movements (rotations, anterior-posterior translations, medial-lateral translations, and horizontal circles) while constraining pelvis motion and moving the thorax or moving the pelvis while minimizing thorax motion, and four isometric trunk exercises (conventional curl-up, reverse curl-up, cross curl-up, and reverse cross curl-up). Surface EMG (upper and lower rectus abdominis, lateral and medial aspects of external oblique, internal oblique, and latissimus dorsi) and 3D lumbar displacements were recorded. Pelvis movements produced higher EMG amplitudes of the oblique abdominals than thorax motions in most trials, and larger lumbar displacements in the medial-lateral translations and horizontal circles. Conversely, thorax movements produced larger rotational lumbar displacement than pelvis motions during rotations and higher EMG amplitudes for latissimus dorsi during rotations and anterior-posterior translations and for lower rectus abdominis during the crossed curl-ups. Thus, different neuromuscular compartments appear when the objective changes from pelvis to thorax motion. This would suggest that both movement patterns should be considered when planning spine stabilization programs, to optimize exercises for the movement and muscle activations desired.

No tratamento matemático dos dados viscosimétricos, foram empregadas cinco equações para determinação dos valores de viscosidade intrínseca: Huggins, Kraemer e Schulz-Blaschke, por extrapolação gráfica; e Solomon-Ciuta, Deb-Chanterjee e, novamente, Schulz-Blaschke, para determinações por um único ponto, que é um método mais rápido e, portanto, de grande interesse industrial. Foram também calculadas as constantes viscosimétricas de Huggins, Kraemer e Schulz-Blaschke, e analisada a qualidade do solvente. Foi verificado que, independentemente da formulação, o isopropanol foi o melhor solvente para os prepolímeros e que todas as equações empregadas para a determinação por um único ponto foram válidas, sendo a de Solomon-Ciuta a mais adequada.In this study the behavior of urethane prepolymers based on poly(propylene glycol (PPG and isophorone diisocyanate (IPDI, in diluted solutions, were studied by viscosimetric measurements, at 30 °C, in two types of solvents with different polarities: isopropyl alcohol and toluene. Five different equations were used to determine intrinsic viscosities values: Huggins; Kraemer and Schulz-Blaschke, by graphic extrapolation; and Solomon-Ciuta; Deb-Chanterjee and; again, Schulz-Blaschke, by a single point determination. The intrinsic viscosities were obtained with two methods (graphic extrapolations and through a single point determination. Viscometric constants from Huggins; Kraemer and Schulz-Blaschke equations were also determined to verify the solvent quality. Regardless of the formulation, isopropyl alcohol was the best solvent for the samples and Solomon-Ciuta equation was the most suitable for the single point

    In utero exposure to certain drugs early in pregnancy may adversely affect nephrogenesis. Exposure to drugs later in pregnancy may affect the renin-angiotensin system, which could have an impact on fetal or neonatal renal function. Reduction in nephron number and renal function could have adverse consequences for the child several years later. Data are limited on the information needed to guide decisions for patients and providers regarding the use of certain drugs in pregnancy. The study of drug nephroteratogenicity has not been systematized, a large, standardized, global approach is needed to evaluate the renal risks of in utero drug exposures.

    Full Text Available Metaplastic changes in the urothelium of the upper urinary tract are relatively infrequent. Metaplasia may present as either squamous or less often glandular differentiation. The process may be associated with chronic inflammation or associated chronic infections. There may be malignant transformation to either squamous cell carcinoma or adenocarcinoma. The demarcation of the metaplastic process in the minor calyces has not been well documented to date. We report the case of a 74-year-old female patient who presented with a history of chronic renal disease and acute pyohydronephrosis. The patient underwent a nephroureterectomy which revealed keratinizing desquamative squamous metaplasia throughout the renal pelvis and upper urinary tract with abrupt termination of metaplasia at the junction of the renal pelvis and the minor calyx (pyramidal zone. Immunohistochemical evaluation documents metaplastic urothelium stained positive for CK5, before converting sharply to simple cuboidal epithelium in the minor calyx (pyramidal zones which stained positive CK7. At the junction of the metaplastic components and low cuboidal lined minor calyceal surfaces, the underlying stroma showed loss of ureteral muscularis mucosa with transition to renal parenchymal type stroma. We believe that this observation is unique and potentially relevant to the etiology and pathophysiology of pelviceal metaplasia.

  10. Nlrp3 prevents early renal interstitial edema and vascular permeability in unilateral ureteral obstruction.

    Directory of Open Access Journals (Sweden)

    Wilco P Pulskens

    Full Text Available Progressive renal disease is characterized by tubulo-interstitial injury with ongoing inflammation and fibrosis. The Nlrp3 inflammasome contributes to these pathophysiological processes through its canonical effects in cytokine maturation. Nlrp3 may additionally exert inflammasome-independent effects following tissue injury. Hence, in this study we investigated potential non-canonical effects of Nlrp3 following progressive renal injury by subjecting WT and Nlrp3-deficient (-/- mice to unilateral ureter obstruction (UUO. Our results revealed a progressive increase of renal Nlrp3 mRNA in WT mice following UUO. The absence of Nlrp3 resulted in enhanced tubular injury and dilatation and an elevated expression of injury biomarker NGAL after UUO. Moreover, interstitial edema was significantly elevated in Nlrp3-/- mice. This could be explained by increased intratubular pressure and an enhanced tubular and vascular permeability. In accordance, renal vascular leakage was elevated in Nlrp3-/- mice that associated with reduced mRNA expression of intercellular junction components. The decreased epithelial barrier function in Nlrp3-/- mice was not associated with increased apoptosis and/or proliferation of renal epithelial cells. Nlrp3 deficiency did not affect renal fibrosis or inflammation. Together, our data reveal a novel non-canonical effect of Nlrp3 in preserving renal integrity and protection against early tubular injury and interstitial edema following progressive renal injury.

    Introduction In sub Saharan Africa, childbirth remains a challenge that creates the need for additional screening tools. Maternal pelvis height, which is currently in use by automotive engineers has previously been shown to have significant associations with various childbirth related outcomes and events. This study set out to determine the associations between maternal: Age, height, weight and number of pregnancies with maternal pelvis height in Ugandan mothers. Methods This was a secondary analysis of maternal birth records from nine Ugandan hospitals, of mothers with singleton pregnancies. Data was analyzed using multilevel regression with respect to maternal pelvis height and additional analysis for tribe and site of childbirth intraclass correlations (ICCs). Results The mean maternal pelvis height was 7.30cm for the 2068 records. Maternal pelvis height was associated with: a 0.01cm reduction per centimeter of maternal height (P=0.02), 0.01cm increase per kg of maternal weight (P<0.01), 0.04cm increase for each additional pregnancy (P=0.03) and 0.03cm increase with respect to tribe of mother (P=0.27), for a constant of 7.97cm (P<0.01). The ICC for tribe was 0.20 (SE=0.08) and 0.37 (SE=0.11) for site. Conclusion Maternal pelvis height was associated with maternal height, maternal weight and number of pregnancies. The site of childbirth had a moderate effect on the above associations with maternal pelvis height. More study on the public health screening value of these measurements in these settings is required. PMID:27800110

    2012-01-01

    Full Text Available Undifferentiated pleomorphic sarcoma is known as a soft tissue sarcoma. Very few cases of this tumor originating from the renal parenchyma or renal capsule have been reported. We report a case of a 70-year-old patient admitted for enormous ureterohydronephrosis and pyelonephritis due to a pelvic ureter lithiasis. After draining by ureteral double J catheter, a nephroureterectomy was performed for nonfunctional kidney confirmed by scintigraphy. The histopathological study shows a pleomorphic undifferentiated sarcoma. The patient was sent to oncologists. Chemotherapy was proposed but the family decided to stop the treatment. The patient passed away 10 months later. Clinicians and pathologists should be aware of the very low occurrence of this renal tumor, which is extremely rare. Currently there is no consensus about its management. Our case extends the literature concerning this tumor.

    To evaluate the imaging findings of uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis. From March 2003 to December 2008, five patients with uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis were evaluated as part of this study. We retrospectively reviewed the CT, ultrasound, and MRI findings as well as the medical records of each patient. The patients initially underwent an imaging study for abdominal pain (n=3), recurrent vaginal bleeding (n=1), and prenatal evaluation (n=1). Of the five patients that underwent US, four had hematocolpos and two of them had hematometra. Moreover, three patients underwent a CT examination. The MR examination of four patients revealed hematocolpos (n=3), hematometra (n=1), and a tubular structure resembling an ectopic ureter (n=2). The gynecologic examination of a patient without hematocolpos revealed a pinpoint hole in the vaginal septum. Two of four patients with hematocolpos underwent a vaginal septectomy, which resulted in an improvement of the symptoms. The most common finding of patients with uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is vaginal fluid collection. Hematometra is not a consistent finding and can be transient according to the menstrual cycle. MR is the most useful imaging modality for the diagnosis of an ectopic ureter.

    The pelvis is one of the most likely affected areas of the human body in case of side impact, especially while people suffer from motor vehicle crashes. With the investigation of pelvis injury on side impact, the injury biomechanical behavior of pelvis can be found, and the data can help design the vehicle security devices to keep the safety of the occupants. In this study, a finite element (FE) model of an isolated human pelvis was used to study the pelvic dynamic response under different side impact conditions. Fracture threshold was established by applying lateral loads of 1000, 2000, 3000, 4000 and 5000 N, respectively, to the articular surface of the right acetabulum. It was observed that the smaller the lateral loads were, the smaller the von Mises stress and the displacement in the direction of impact were. It was also found that the failure threshold load was near 3000 N, based on the fact that the peak stress would not exceed the average compressive strength of the cortical bone. It could well be concluded that with better design of car-door and hip-pad so that the side impact force was brought down to 3000 N or lower, the pelvis would not be injured.

    A prevailing rationale for equine assisted therapies is that the motion of a horse can provide sensory stimulus and movement patterns that mimic those of natural human activities such as walking. The purpose of this study was to quantitatively measure and compare human pelvis motions when walking to those when riding a horse. Six able-bodied children (inexperienced riders, 8-12years old) participated in over-ground trials of self-paced walking and leader-paced riding on four different horses. Five kinematic measures were extracted from three-dimensional pelvis motion data: anteroposterior, superoinferior, and mediolateral translations, list angle about the anteroposterior axis, and twist angle about the superoinferior axis. There was generally as much or more variability in motion range observed between riding on the different horses as between riding and walking. Pelvis trajectories exhibited many similar features between walking and riding, including distorted lemniscate patterns in the transverse and frontal planes. In the sagittal plane the pelvis trajectory during walking exhibited a somewhat circular pattern whereas during riding it exhibited a more diagonal pattern. This study shows that riding on a horse can generate movement patterns in the human pelvis that emulate many, but not all, characteristics of those during natural walking.

    Complete staghorn calculi are typically managed with percutaneous nephrolithotomy (PCNL). However, dilating nephrostomy and inserting a nephro access sheath can be difficult to perform without hydronephrosis. We reported the procedure of ureteroscopy-assisted retrograde nephrostomy (UARN) during PCNL. UARN is effective without dilating the renal collecting system in cases of complete staghorn calculi. A 63-year old female with a left complete staghorn renal calculus was referred to our hospital. Under general and epidural anesthesia, the patient was placed in a modified-Valdivia position. A flexible ureteroscope was inserted and a Lawson retrograde nephrostomy puncture wire was advanced into the flexible ureteroscope. The puncture wire was forwarded along the route from the renal pelvis to the exit skin. Calculus fragmentation was done using a pneumatic lithotripter and the Ho: YAG laser. UARN during PCNL was effective for the treatment of a complete staghorn calculus.

    Ureteral peristaltic mechanism facilitates urine transport from the kidney to the bladder. Numerical analysis of the peristaltic flow in the ureter aims to further our understanding of the reflux phenomenon and other ureteral abnormalities. Fluid-structure interaction (FSI) plays an important role in accuracy of this approach and the arbitrary Lagrangian-Eulerian (ALE) formulation is a strong method to analyze the coupled fluid-structure interaction between the compliant wall and the surrounding fluid. This formulation, however, was not used in previous studies of peristalsis in living organisms. In the present investigation, a numerical simulation is introduced and solved through ALE formulation to perform the ureteral flow and stress analysis. The incompressible Navier-Stokes equations are used as the governing equations for the fluid, and a linear elastic model is utilized for the compliant wall. The wall stimulation is modeled by nonlinear contact analysis using a rigid contact surface since an appropriate model for simulation of ureteral peristalsis needs to contain cell-to-cell wall stimulation. In contrast to previous studies, the wall displacements are not predetermined in the presented model of this finite-length compliant tube, neither the peristalsis needs to be periodic. Moreover, the temporal changes of ureteral wall intraluminal shear stress during peristalsis are included in our study. Iterative computing of two-way coupling is used to solve the governing equations. Two phases of nonperistaltic and peristaltic transport of urine in the ureter are discussed. Results are obtained following an analysis of the effects of the ureteral wall compliance, the pressure difference between the ureteral inlet and outlet, the maximum height of the contraction wave, the contraction wave velocity, and the number of contraction waves on the ureteral outlet flow. The results indicate that the proximal part of the ureter is prone to a higher shear stress during

    Purpose. To determine (1) the reasons for the frequently long delay in the diagnosis of an infrasphincteric ectopic ureter in girls, and (2) what role the radiologist can play in decreasing the delay. Materials and methods. Twelve girls were referred to our hospital from June 1994 until April 1997 for evaluation of constant urinary dribbling and/or vaginal discharge. Available imaging studies, radiology reports, and clinic notes were reviewed. Results. Mean age at the time of diagnosis was 6 years 7 months (range 2 years 10 months to 11 years 11 months). Mean delay until diagnosis after presentation was 2 years 5 months. Excluding the one girl whose ectopic ureter was diagnosed while she was still in diapers, mean age at the time of the first parental ``complaint`` was 4 years 9 months. The significance of the classic history of constant urinary dribbling was not recognized by physicians in 7 girls for 4 months to 7 years 10 months after presentation. Physical exam was not meticulously performed, as the ectopic orifice was visible in 8 of 12 girls. Imaging studies were ineffectively utilized: no imaging was done (for 2 years in 2 girls), inappropriate studies were done (ultrasound and voiding cystourethrography) and were misleading, studies were called normal when they were not (ultrasound and excretory urography), or perinatal imaging led to the incorrect assumption of a congenitally absent kidney in one girl and a multicystic dysplastic kidney in another. Excretory urography (EU) was diagnostic in all 10 girls with a duplex kidney, and computed tomography (CT) was supportive in 2 with a dysplastic kidney. CT was an adjunct in 3 girls; a Tc-99m-dimercaptosuccinic acid (DMSA) scan was needed in 2. Conclusion. The classic history of constant urinary dribbling in a successfully toilet-trained girl should immediately lead to an imaging search for the portion of kidney (or entire kidney) drained by an infrasphincteric ectopic ureter. EU should usually be the first

    Full Text Available Aim: Crossed fused renal ectopia is a rare congenital malformation, which is reported to be usually asymptomatic but may have varied presentations. This survey was conducted to study the clinical profile and the challenges posed in the management of this entity. Materials and Methods: Retrospective analysis of 6 patients diagnosed to have crossed fused renal ectopia during 1997-2010. The diagnosis was confirmed during surgical exploration in one patient. In one patient it was detected on antenatal ultrasonography and in the other 4 patients it was detected during investigations for abdominal pain, abdominal mass, anorectal malformation and urinary tract infection. Results: The left moiety was crossed and fused with the right moiety in 4 cases. Ultrasonography was found to be a good screening investigation with useful diagnostic contributions from CT scans, radionuclide scintigraphy and magnetic resonance urography. Micturating cystourethrography revealed presence of VUR in 4 cases, 3 of whom have undergone ureteric reimplantation. Two patients required pyeloplasty for pelviureteric junction obstruction; in one of these patients the upper ureter was entrapped in the isthmus. In one patient, a non-functioning moiety resulted in nephrectomy. All children were asymptomatic at last follow-up with stable renal functions. Conclusions: Crossed fused renal ectopia was detected in most patients during investigation for other problems. It was found more commonly in boys. The left moiety was crossed to the right in the majority of cases. Associated urological problems were found in most cases and required the appropriate surgical management.

    We developed a three-dimensional finite element model of the pelvis. According to Letournel methods, we established a pelvis model of T-shaped fracture with its three different fixation systems, i. e. double column reconstruction plates, anterior column plate combined with posterior column screws and anterior column plate combined with quadrilateral area screws. It was found that the pelvic model was effective and could be used to simulate the mechanical behavior of the pelvis. Three fixation systems had great therapeutic effect on the T-shaped fracture. All fixation systems could increase the stiffness of the model, decrease the stress concentration level and decrease the displacement difference along the fracture line. The quadrilateral area screws, which were drilled into cortical bone, could generate beneficial effect on the T-type fracture. Therefore, the third fixation system mentioned above (i. e. the anterior column plate combined with quadrilateral area screws) has the best biomechanical stability to the T-type fracture.

    Full Text Available We performed a left nephroureterectomy for a gentleman with transitional cell carcinoma of the upper ureter. Histological analysis revealed it to be a T1 lesion, but to be highly mitotically active. The gentleman defaulted on adjuvant therapy and defaulted on follow-up. He represented with symptoms of acute spinal cord compression and magnetic resonance imaging demonstrated a lesion at T6/7. Neurosurgical resection of the lesion showed it to be a metastatic deposit from the ureteric primary. Despite surgical debulking and subsequent radiotherapy to the lesion, the patient died secondary to metastatic complications. This case report is of interest to the surgeon as it demonstrates both the high metastatic potential of upper tract carcinomas and educates the surgeon on the presentation of acute spinal cord compression.

    2014-04-01

    With the widespread use of whole-body fluorodeoxyglucose (FDG)-PET/computed tomography as a diagnostic tool in patients with cancer, incidental findings are of increasing importance. This is particularly true within the pelvis, where several benign findings might present with increased FDG uptake. In addition, physiologic excretion of radiotracer by way of the urinary tract can complicate image analysis. This article reviews potential incidental benign findings in the pelvis that one should be aware of when interpreting FDG-PET/computed tomography scans.

    Computed tomography (CT) has become the standard of care for evaluation and follow-up for a wide range of abdominal and pelvic pathology. Many incidental osseous and articular abnormalities of the pelvis are detected on these studies, most of which have a benign etiology. However, most of these studies are interpreted by nonmusculoskeletal radiologists, who may not be familiar with the CT appearances of these benign musculoskeletal abnormalities. Uncertainty often leads to mischaracterization or unnecessary follow-up, resulting in increased health care costs and patient anxiety. This article reviews the CT appearance of the benign musculoskeletal entities that occur in pelvis.

    Crossed renal ectopia is a rare urinary system anomaly which mostly is asymptomatic and is diagnosed incidentally. Urinary obstruction, infection, and neoplasia of the urinary system and nephrolithiasis are main complications of this anomaly. A 6-year-old boy admitted to the hospital with colicky abdominal pain and nausea. Abdominal examination revealed tenderness in right lower quadrant. Urine analysis and culture were normal. Kidney ultrasonography showed right kidney in pelvis cavity with no kidney tissue in left side. TC 99-DMSA scan demonstrated no radiotracer accumulation in the normal renal area. Radiotracer accumulation was seen in the pelvis area with a deviation to the left. Voiding cystoureterogram revealed right sided grade II vesicoureteral reflux. Severe urological anomalies in children may be asymptomatic or have nonspecific symptoms such as abdominal pain. PMID:27689123

    Newhouse, J H; Pfister, R C

    1981-01-01

    Nephrostomy catheters offer nonsurgical modes of therapy for some renal stones. Continuous lavage of the stones using hemiacidrin (Renacidin) for struvite stones, THAM-E or acetylcysteine for cystine stones, and bicarbonate solution for uric acid stones may dissolve either entire stones or stone fragments remaining after surgery. Although irrigation is not without potential complications, recent developments in technique have minimized these. Nephrostomy tubes can also be used to transmit stone baskets through steerable catheters to snare stones from the upper collecting system or from the ureter; any stone that can be engaged and withdrawn through the tube tract can be removed; stones larger than those which can be safely extracted through the ureterovesical junction can be so treated. Neither of these procedures requires general anesthesia, the rate of serious morbidity is low, and the required hospital stay is often less than that for surgery; these modes of therapy are therefore valuable for certain patients.

    Full Text Available A 77-year-old female, who suffered from rheumatoid arthritis and hypothyroidism, developed severe muscle weakness. Clinical features, blood results and muscle biopsy suggested a possible diagnosis of dermatomyositis. A computed tomography of the chest, abdomen and pelvis showed a solid mass in the left kidney. She underwent a left laparoscopic nephrectomy and histology confirmed conventional (clear cell renal cell carcinoma. She recovered slowly and almost back to normal life after 6 months. Early appreciation of the typical skin rash may provide a clue to the diagnosis and screening for neoplasm may improve prognosis.

    To explore the factors affecting the residual stones after percutaneous nephrolithotomy (PCNL) in patients with renal calculus. A retrospective analysis was performed for 1 200 patients who were affected by renal calculus and treated with PCNL between Jan 2008 and May 2014 in People's Hospital of Anyang City. Among those patients, 16 were diagnosed as bilateral renal stone and had two successive operations. The size, location and number of stones, previous history of surgery, the degree of hydronephrosis, urinary infection were included in the univariate analysis. Significant factors in univariate analysis were included in the multivariate analysis to determine factors affecting stone residual. A total of 385 cases developed stone residual after surgery. The overall residual rate was 31.7%. In univariate analysis, renal pelvis combined with caliceal calculus (P=0.006), stone size larger than 4 cm (P=0.005), stone number more than 4 (P=0.002), the amount of bleeding more than 200 ml (P=0.025), operation time longer than 120 minutes (P=0.028) were associated with an increased rate of stone residual. When subjected to the Cox multivariate analysis, the independent risk factors for residual stones were renal pelvis combined with caliceal calculus (P=0.049), stone size larger than 4 cm (P=0.038) and stone number more than 4 (P=0.018). Factors affecting the incidence of residual stones after PCNL are the size, location and number of stones. Larger size stone and the presence of renal pelvis combined with caliceal calculus are significantly associated with residual stones. Nevertheless, stone number less than 4 indicates an increased stone clearance rate.

    Patients with unilateral dysvascular transtibial amputation (TTA) have a higher risk of developing low back pain than their healthy counterparts, which may be related to movement compensations used in the absence of ankle function. Assessing components of segmental angular momentum provides a unique framework to identify and interpret these movement compensations alongside traditional observational analyses. Angular momentum separation indicates two components of total angular momentum: (1) transfer momentum and (2) rotational momentum. The objective of this investigation was to assess movement compensations in patients with dysvascular TTA, patients with diabetes mellitus (DM), and healthy controls (HC) by examining patterns of generating and arresting trunk and pelvis segmental angular momenta during gait. We hypothesized that all groups would demonstrate similar patterns of generating/arresting total momentum and transfer momentum in the trunk and pelvis in reference to the groups (patients with DM and HC). We also hypothesized that patients with amputation would demonstrate different (larger) patterns of generating/arresting rotational angular momentum in the trunk. Patients with amputation demonstrated differences in trunk and pelvis transfer angular momentum in the sagittal and transverse planes in comparison to the reference groups, which indicates postural compensations adopted during walking. However, patients with amputation demonstrated larger patterns of generating and arresting of trunk and pelvis rotational angular momentum in comparison to the reference groups. These segmental rotational angular momentum patterns correspond with high eccentric muscle demands needed to arrest the angular momentum, and may lead to consequential long-term effects such as low back pain.

    The prostate is an imaging area of growing concern related with aging. Prostate cancer and benign prostatic hyperplasia are the most common diseases and significant cause of death for elderly men. Hence, the conductivity imaging of the male pelvis is a challenging task with a clinical significance. In this study, we performed in vivo MREIT imaging experiments of the canine male pelvis using a 3T MRI scanner. Adopting carbon-hydrogel electrodes and a multi-echo pulse sequence, we could inject as much as 10 mA current in a form of 51 ms pulse into the pelvis. Collecting magnetic flux density data inside the pelvis subject to multiple injection currents, we reconstructed cross-sectional conductivity images using a MREIT software package CoReHA. Scaled conductivity images of the prostate show a clear contrast between the central and peripheral zones which are related with prostate diseases including cancer and benign prostatic hyperplasia. In our future work, we will focus on prostate cancer model animal experiments.

    Man, with his erect posture, evolves in a world subject to the laws of gravity. His spine reflects these constraints. The morphology and static of human spine and biomechanical relationships between spine and pelvis are in direct relation with bipedia. Owing to this position the pelvis widened and straightened, characteristic sagittal spinal curves appeared and the perispinal muscles were deeply reorganized. Each pelvis is characterized by an important anatomical landmark: the pelvic incidence that reflects the sagittal morphology of the pelvis. Based on this anatomical characteristic, a chain of reactions determines the more efficient equilibrium of the whole body in the sagittal plane in term of energy consumption. Incidence affects the sacral slope, which determines lumbar lordosis, which itself influences pelvic tilt, thoracic kyphosis, and even hip and knee position. All these landmarks can easily be studied on a sagittal radiograph. Knowledge of these functional relationships is essential to understand the origin of low back pain, sagittal imbalance and above all before surgical treatment of spine disorders especially when arthrodesis is considered.

  7. A Regional Dose and Image Quality Survey for Chest, Abdomen and Pelvis Radiographs in Paediatrics

    2000-07-01

    A dosimetric survey in paediatric radiology is currently being carried out, aiming at the assessment of patient dose and image quality for chest, abdomen and pelvis radiographs in some age categories at five hospitals in the Tarragona area. Entrance surface dose measurements were performed using homogeneous PMMA phantoms. Effective doses were assessed through the application of published conversion factors. The range of entrance doses averaged by sites was 75-729 {mu}Gy for pelvis radiographs of children aged 5 months, 813-1600 {mu}Gy for pelvis radiographs of children aged 5 years, 94-250 {mu}Gy for chest radiographs of children aged 5 years and 980-2300 {mu}Gy for abdomen radiographs of children aged 5 years. The reference dose values given in the European Guidelines on Quality Criteria for Diagnostic Radiographic Images in Paediatrics were exceeded at two or more hospitals for all projections. The range of average effective dose for the analysed examinations was 14-245 {mu}Sv. The maximum ratios of effective dose by sites varied between 2.2 and 11 for the analysed projections. By examination type, average values in the range 100 to 245 {mu}Sv were estimated for 5 year pelvis and abdomen examinations. (author)

    The purpose of the study was to determine if abdomen/pelvis computed tomography (CT) can be safety omitted in the initial staging of a subgroup of children affected by Hodgkin Lymphoma (HL). Every participating center of A.I.E.O.P (Associazione Italiana di Ematologia ed Oncologia Pediatrica) sent local staging reports of 18F-fluorodeoxyglucose positron emission tomography (PET) and abdominal ultrasound (US) along with digital images of staging abdomen/pelvis CT to the investigation center where the CT scans were evaluated by an experienced pediatric radiologist. The local radiologist who performed the US was unaware of local CT and PET reports (both carried out after US), and the reviewer radiologist examining the CT images was unaware of local US, PET and CT reports. A new abdominal staging of 123 patients performed on the basis of local US report, local PET report, and centralized CT report was then compared to a simpler staging based on local US and PET. No additional lesion was discovered by CT in patients with abdomen/pelvis negativity in both US and PET or isolated spleen positivity in US (or US and PET), and so it seems that in the initial staging, abdomen/pelvis CT can be safety omitted in about 1/2 to 2/3 of children diagnosed with HL.

    Characterizing australopith pelvic morphology has been difficult in part because of limited fossilized pelvic material. Here, we reassess the morphology of an under-studied adult right ilium and pubis (Sts 65) from Member 4 of Sterkfontein, South Africa, and provide a hypothetical digital reconstruction of its overall pelvic morphology. The small size of the pelvis, presence of a preauricular sulcus, and shape of the sciatic notch allow us to agree with past interpretations that Sts 65 likely belonged to a female. The morphology of the iliac pillar, while not as substantial as in Homo, is more robust than in A.L. 288-1 and Sts 14. We created a reconstruction of the pelvis by digitally articulating the Sts 65 right ilium and a mirrored copy of the left ilium with the Sts 14 sacrum in Autodesk Maya. Points along the arcuate line were used to orient the ilia to the sacrum. This reconstruction of the Sts 65 pelvis looks much like a "classic" australopith pelvis, with laterally flared ilia and an inferiorly deflected pubis. An analysis of the obstetric dimensions from our reconstruction shows similarity to other australopiths, a likely transverse or oblique entrance of the neonatal cranium into the pelvic inlet, and a cephalopelvic ratio similar to that found in humans today.

    The fossil record of the human pelvis reveals the selective priorities acting on hominin anatomy at different points in our evolutionary history, during which mechanical requirements for locomotion, childbirth and thermoregulation often conflicted. In our earliest upright ancestors, fundamental alterations of the pelvis compared with non-human primates facilitated bipedal walking. Further changes early in hominin evolution produced a platypelloid birth canal in a pelvis that was wide overall, with flaring ilia. This pelvic form was maintained over 3-4 Myr with only moderate changes in response to greater habitat diversity, changes in locomotor behaviour and increases in brain size. It was not until Homo sapiens evolved in Africa and the Middle East 200 000 years ago that the narrow anatomically modern pelvis with a more circular birth canal emerged. This major change appears to reflect selective pressures for further increases in neonatal brain size and for a narrow body shape associated with heat dissipation in warm environments. The advent of the modern birth canal, the shape and alignment of which require fetal rotation during birth, allowed the earliest members of our species to deal obstetrically with increases in encephalization while maintaining a narrow body to meet thermoregulatory demands and enhance locomotor performance.

    Knowledge of organ and effective doses achieved during paediatric X-ray examinations is an important prerequisite for assessment of radiation burden to the patient. Conversion coefficients for reconstruction of organ and effective doses from entrance doses for pelvis and hip joint radiographs of 0-, 1-, 5-, 10-, 15- and 30-year-old patients are provided regarding the Guidelines of Good Radiographic Technique of the European Commission. Using the personal computer program PCXMC developed by the Finnish Centre for Radiation and Nuclear Safety (Saeteilyturvakeskus STUK), conversion coefficients for conventional pelvis and hip joint radiographs were calculated by performing Monte Carlo simulations in mathematical hermaphrodite phantom models representing patients of different ages. The clinical variation of radiation field settings was taken into consideration by defining optimal and suboptimal standard field settings. Conversion coefficients for the reconstruction of organ doses in about 40 organs and tissues from measured entrance doses during pelvis and hip joint radiographs of 0-, 1-, 5-, 10-, 15- and 30-year-old patients were calculated for the standard sagittal beam projection and the standard focus detector distance of 115 cm. The conversion coefficients presented can be used for organ dose assessments from entrance doses measured during pelvis and hip joint radiographs of children and young adults with all field settings within the optimal and suboptimal standard field settings.

    Background: In pre-operative planning for total hip arthroplasty (THA), femoral offset (FO) is frequently underestimated on AP pelvis radiographs as a result of inaccurate patient positioning, imprecise magnification, and radiographic beam divergence. The aim of the present study was to evaluate the accuracy and reliability of predicting three-dimensional (3-D) FO from standardised AP pelvis radiographs. Methods: In a retrospective cohort study, pre-operative AP pelvis radiographs, AP hip radiographs and CT scans of a consecutive series of 345 patients (345 hips, 146 males, 199 females, mean age 60 (range: 40–79) years, mean body-mass-index 27 (range: 19–57) kg/m{sup 2}) with primary end-stage hip OA were reviewed. Patients were positioned according to a standardised protocol and all images were calibrated. Using validated custom programmes, FO was measured on corresponding radiographs and CT scans. Measurement reliability was evaluated using intra-class-correlation-coefficients. To predict 3-D FO from AP pelvis measurements and to assess the accuracy compared to CT, the entire cohort was randomly split into subgroups A and B. Gender specific regression equations were derived from group A (245 patients) and the accuracy of prediction was evaluated in group B (100 patients) using Bland–Altman plots. Results: In the entire cohort, mean FO was 39.2 mm (95%CI: 38.5–40.0 mm) on AP pelvis radiographs, 44.1 mm (95%CI: 43.4–44.9 mm) on AP hip radiographs and 44.6 mm (95%CI: 44.0–45.2 mm) on CT scans. In group B, we observed no significant difference between gender specific predicted FO (males: 48.0 mm, 95%CI: 47.1–48.8 mm; females: 42.0 mm, 95%CI: 41.1–42.8 mm) and FO as measured on CT (males: 47.7 mm, 95%CI: 46.1–49.4 mm, p = 0.689; females: 41.6 mm, 95%CI: 40.3–43.0 mm, p = 0.607). Conclusions: The present study suggests that FO can be accurately and reliably predicted from AP pelvis radiographs in patients with primary end-stage hip osteoarthritis

    Percutaneous renal surgery is routine therapy for a number of renal pathologies. It is a technique not without complications, often serious ones, of which the worst is bleeding. We reviewed our experience of the incidence, etiology, and management of this serious complication to determine a protocol of treatment that will minimize the consequences. Between 1984 and 1996, we carried out 976 percutaneous operations for reno-calix stones, pyeloureteral junction stenosis, neoplasia of the renal pelvis, diagnosis, and ureteral prostheses. In all cases, the percutaneous access was achieved through a lower calix in the posterior axillary line with the patient in a prone position. The lithotripsy was performed with ultrasound and balistic energy lithotripters. Antegrade endopyelotomy was performed according to our technique. At the end of the procedure, a nephrostomy tube was positioned, 24F for lithotripsy and 16F for endopyelotomy. The nephrostomy tube was removed after 24 to 48 hours. In this series, 146 patients (15%) presented significant perioperative bleeding. In 97 cases (10%), this complication was resolved with the repositioning of the nephrostomy tube, bedrest in a supine position, and observation, whereas in 49 cases (5%), clamping of the nephrostomy tube for 24 hours was necessary. In 56 patients (5.7%), two blood transfusions were necessary, and three patients (0.3%) had bleeding 10, 12, and 20 days after the operation, which was resolved by embolization of the lacerated vessel.

    Histone deacetylase (HDAC) inhibitors are promising anti-fibrosis drugs; however, nonselective inhibition of class I and class II HDACs does not allow a detailed elucidation of the individual HDAC functions in renal fibrosis. In this study, we investigated the effect of MS-275, a selective class I HDAC inhibitor, on the development of renal fibrosis in a murine model of unilateral ureteral obstruction (UUO) and activation of cultured renal interstitial fibroblasts. The UUO model was established by ligation of the left ureter and the contralateral kidney was used as a control. At seven days after UUO injury, kidney developed fibrosis as indicated by deposition of collagen fibrils and increased expression of collagen I, fibronectin and alpha-smooth muscle actin (alpha-SMA). Administration of MS-275 inhibited all these fibrotic responses and suppressed UUO-induced production of transforming growth factor-beta1 (TGF-beta), increased expression of TGF-beta receptor I, and phosphorylation of Smad-3. MS-275 was also effective in suppressing phosphorylation and expression of epidermal growth factor receptor (EGFR) and its downstream signaling molecule, signal transducer and activator of transcription-3. Moreover, class I HDAC inhibition reduced the number of renal tubular cells arrested in the G2/M phase of the cell cycle, a cellular event associated with TGF-beta1overproduction. In cultured renal interstitial fibroblasts, MS-275 treatment inhibited TGF-beta induced phosphorylation of Smad-3, differentiation of renal fibroblasts to myofibroblasts and proliferation of myofibroblasts. These results demonstrate that class I HDACs are critically involved in renal fibrogenesis and renal fibroblast activation through modulating TGF-beta and EGFR signaling and suggest that blockade of class I HDAC may be a useful treatment for renal fibrosis.

    Full Text Available The insertion of indwelling ureteric stents is a routine procedure in urology practice. Complications secondary to the insertion of these stents have also increased, such as stent encrustation, stent fragmentation, stone formation, and recurrent urinary tract infections. Knot formation within the renal pelvis or in the coiled portion of the ureteral stent is an extremely rare condition, with less than 15 cases reported in literature. The authors report a rare case of knotted stent, complicated by an obstructive acute renal failure and urosepsis, in a patient with a solitary functioning kidney.

    Abstract Background: Endourology is a widely used means by which to manage urolithiasis. Patient anatomy can oftentimes limit what can be accomplished with current technology. Case Presentation: This is a case of a patient with renal and ureteral stones within a transplant kidney. Her anatomy would not allow for a standard retrograde ureteroscopic approach. We describe a method by which to overcome this difficult scenario by using a rigid cystoscope as a platform by which a ureteroscope was passed to allow for stone removal. Conclusion: For this difficult case, we effectively used our instruments to achieve our goal of retrograde ureteroscopy in a transplant kidney with an unfavorably angulated ureter. PMID:27579433

    Renal duplication accompanied by ureteral ectopia is an uncommon urinary congenital abnormality. We report the case of a 21-year-old girl who suffered from lifelong continuous urinary leakage. She was finally diagnosed with bilateral duplicated collecting systems complicated with right ectopic ureteral orifice - an extremely rare case. The patient underwent ureteric re-implantation for the ectopic side, and her urinary incontinence ceased soon thereafter. In this case, traditional imaging failed to show the exact insertion of an ectopic ureter. However, magnetic resonance urography combined with retrograde intubation radiography successfully depicted the point of ureteric insertion, which may make the diagnostic process accurate and efficient.

    Background Multidetector-row CT (MDCT) has been evolving to the standard evaluating method of potential living donor in most centers, and can provide excellent details for selecting candidates and determining surgical technique.This study aimed to assess the value of MDCT in evaluation of the anatomy of living kidney donors and to reveal the prevalence of renal vascular variations in a Chinese population.Methods One hundred and four potential donors underwent MDCT and the data sets were post-processed for reformatted images with various techniques, such as maximum intensity projection (MIP), a volume-rendering technique (VR), and multiplanar reformation (MPR). Donor nephrectomies were performed on 97 candidates after MDCT evaluation with the findings during surgery constituting the standard of reference. Resulting MDCT images were compared with actual anatomy found during surgery. Results The MDCT images accurately displayed the anatomic structure of the main renal arteries and veins as well as the upper ureters, except in one case with horseshoe kidney. The prevalence of accessory arteries revealed in images was 27.2% (28/103) and early branching was found in 12.6% (13/103). Compared with findings during surgery, the detection of accessory arteries in MDCT images was 85.7% (6/7), and the detection of larger accessory arteries (>1.5 mm in diameter) was 100%. Detection of early branching was 100%.Conclusion MDCT helps accurately evaluate the renal anatomy of potential donors thus facilitating the planning of surgery.

    Background In 2008, infants in some areas of China suffered from stones of the urinary system which were caused by melamine-contaminated milk formula. Most of the infants were asymptomatic, and a few suffered from acute renal failure induced by urinary obstruction by stones. This study aimed to assess the significance of blood purification therapy in treatment of infants with acute obstructive oligo-anuric renal failure. Corrective perception, timely diagnosis, and active treatment of this complex disease are critical factors that guarantee a quick recovery of renal function of infants and help them to prevent multiple organ system failure.Methods Thirteen infants with acute renal failure induced by urinary multiple obstruction caused by melamine-containing stones who had been admitted to Beijing Children's Hospital Affiliated to Capital Medical University in 2008 were investigated for the epidemiological characteristics, image features and indications of dialysis. All these infants were treated with dialysis. The efficacy of dialysis was compared with that of two control groups treated with cystoscopic retrograde catheterization into the ureter and medical treatment for the recovery of renal function.Results The 13 infants with life-threatening complications treated with dialysis showed a blood urea nitrogen (BUN) level of (30.9±7.9) mmol/L and a creatinine (Cr) level of (572+173) pmol/L. Of these infants, 8 were treated with peritoneal dialysis (PD), and 5 with hemodialysis (HD). Ten infants recovered to urinate 24-72 hours after dialysis and 3 infants with persistent ureteral obstruction were further treated with cystoscopic retrograde catheterization into the ureter for drainage, and urination resumed soon after the operation. The average time of PD and HD were (2.1±0.8) days and (1.2±0.4) days, respectively. The total average time of PD and HD dialysis was (1.77±0.83) days. The recovery time of renal function of infants after dialysis was (3.08±1.20) days

    Introduction Fetal head descent is used to demonstrate the maternal pelvis capacity to accommodate the fetal head. This is especially important in low resource settings that have high rates of childbirth related maternal deaths and morbidity. This study looked at maternal height and an additional measure, maternal pelvis height, from automotive engineering. The objective of the study was to determine the associations between maternal: height and pelvis height with the rate of fetal head descent in expectant Ugandan mothers. Methods This was a cross sectional study on 1265 singleton mothers attending antenatal clinics at five hospitals in various parts of Uganda. In addition to the routine antenatal examination, each mother had their pelvis height recorded following informed consent. Survival analysis was done using STATA 12. Results It was found that 27% of mothers had fetal head descent with an incident rate of 0.028 per week after the 25th week of pregnancy. Significant associations were observed between the rate of fetal head descent with: maternal height (Adj Haz ratio 0.93 P < 0.01) and maternal pelvis height (Adj Haz ratio 1.15 P < 0.01). Conclusion The significant associations observed between maternal: height and pelvis height with rate of fetal head descent, demonstrate a need for further study of maternal pelvis height as an additional decision support tool for screening mothers in low resource settings.

    To evaluate the prevalence of abnormalities seen on sonography and renal scintigraphy, according to the grade of vesicoureteral reflux (VUR) on in voiding cystourethrography(VCUG). One hundred and forty-nine patients (age range: 1 months-10 years) with urinary tract infection underwent sonography, VCUG, and renal scans, and 32 showed VUR on VCUG. We retrospectively evaluated the frequency and characteristic findings of sonographic abnormalities according to the grade of VUR, and also the frequency of cortical defects seen on renal scans of 32 patients with VUR. The remaining 117 patients without VUR were also evaluated for the frequency of abnormal findings seen on sonography and renal scans. Among 32 patients (49 kidneys) with VUR, abnormal findings were not detected in 17 (29 kidneys) on sonography; thus, findings were abnormal in 15 (20 kidneys, 41%). Among these 20 kidneys, renal calyceal and/or pelvic dilatation and dilatation of distal ureter were seen in 11, all of which were grade 4-5 VUR. Renal pelvic dilatation only was noted in eight kidneys; two were grade 1-3 and six were grade 4-5 VUR. Nineteen patients (24 kidneys, 49%) showed focal cortical defects on renal scintigraphy. Six kidneys were grade 1-3, and 18 kidneys were grade 4-5 VUR. Of 117 patients without VUR, 34 patients (29%) showed renal pelvic dilatation on sonography and in 14 patients (12%), cortical defects were seen on renal scintigraphy. Among 32 patients with VUR, 41% showed abnormal sonographic findings and in 49%, cortical defects were seen on renal scintigraphy. With a higher grade of VUR, the prevalence of abnormalities increased on both sonography and renal scintigraphy. Sonographic demonstration of renal caliceal and/or pelvic dilatation associated with ipsilateral distal ureteric dilatation was the characteristic finding in high grade VUR.=20.

    Full Text Available Renal squamous cell cancer is one of the rare primary urothelial tumors with only a handful of cases reported in literature. Because of high grade, advanced and late presentation, they herald a grave prognosis. They are frequently associated with calculus disease, smoking, phenacetin consumption and foci of squamous metaplasia due to chronic irritation. Nephroureterectomy is the treatment of choice for such tumors. We hereby present a case of 59 year old female who presented with squamous cell cancer of renal pelvis. The case presented here is different from what has already been reported in literature, as the patient had no antecedent risk factors for renal squamous cell carcinoma.-------------------------------------------------Cite this article as: Pahwa M, Pahwa AR, Girotra M, Chawla A.

    Computed tomography was used in a consecutive series or 74 transplantations in the diagnosis of complications to renal allograft surgery. Thirty-nine peritransplant fluid collections were demonstrated, 13 of these were subjected to surgery. A diagnosis of the specific nature of the fluid collection was possible in cases of urine leakage and fresh hematomas. The method was sensitive in defining the size of the renal pelvis though differentiation between postrenal obstruction and large non-obstructed collecting system was not always possible. The cause of postrenal obstruction could be identified in 5 patients out of 10. Renal infarctions were diagnosed in 8 patients. Computed tomography seems to be a highly accurate method in the diagnosis of complications to renal allograft surgery. The method can be used independent of transplant function and the use of contrast medium is necessary only to verify urine leakage and infarction.

    Full Text Available Renal TB is difficult to diagnose, because many patients present themselves with lower urinary symptoms which are typical of bacterial cystitis. We report a case of a young woman with renal TB and ESRD. She was admitted with complaints of adynamia, anorexia, fever, weight loss, dysuria and generalized edema for 10 months. At physical examination she was febrile (39ºC, and her abdomen had increased volume and was painful at palpation. Laboratorial tests showed serum urea=220mg/dL, creatinine=6.6mg/dL, hemoglobin=7.9g/dL, hematocrit=24.3%, leukocytes=33,600/mm³ and platelets=664,000/mm³. Urinalysis showed an acid urine (pH=5.0, leukocyturia (2+/4+ and mild proteinuria (1+/4+. She was also oliguric (urinary volume <400mL/day. Abdominal echography showed thick and contracted bladder walls and heterogeneous liquid collection in the left pelvic region. Two laparotomies were performed, in which abscess in pelvic region was found. Anti-peritoneal tuberculosis treatment with rifampin, isoniazid and pyrazinamide was started. During the follow-up, the urine culture was found to be positive for M. tuberculosis. Six months later the patient had complaints of abdominal pain and dysuria. New laboratorial tests showed serum urea=187mg/dL, creatinine=8.0mg/dL, potassium=6.5mEq/L. Hemodialysis was then started. The CT scan showed signs of chronic nephropathy, dilated calyces and thinning of renal cortex in both kidneys and severe dilation of ureter. The patient developed neurologic symptoms, suggesting tuberculous meningoencephalitis, and died despite of support measures adopted. The patient had ESRD due to secondary uropathy to prolonged tuberculosis of urinary tract that was caused by delayed clinical and laboratorial diagnosis, and probably also due to inadequate antituberculous drugs administration.

    2002-03-01

    Anatomic and physiologic adaptations within the renal system during pregnancy are significant. Alterations are seen in renal blood flow and glomerular filtration, resulting in changes in normal renal laboratory values. When these normal renal adaptations are coupled with pregnancy-induced complications or preexisting renal dysfunction, the woman may demonstrate a reduction of renal function leading to an increased risk of perinatal morbidity and mortality. This article will review normal pregnancy adaptations of the renal system and discuss common pregnancy-related renal complications.

    Background: Autoimmune pancreatitis (AIP) is a chronic inflammatory condition characterized by IgG4-positive plasma cells. Recent evidence suggests that it is a systemic disease affecting various organs. Tubulointerstitial nephritis has been reported in association with AIP. Purpose: To investigate the incidence and types of renal involvement in patients with AIP. Material and Methods: Eighteen patients with no history of renal disease and a diagnosis of AIP (on the basis of histopathologic findings or a combination of characteristic imaging features, increased serum IgG4 levels, and response to steroid treatment) were included. All patients underwent computed tomography (CT) imaging and follow-up ranged from 6 months to 2 years. CT images were reviewed for the presence of renal lesions. Results: Seven patients had renal involvement (38.8%). None of the lesions was visible on non-contrast-enhanced CT scan. Parenchymal lesions appeared as multiple nodules showing decreased enhancement (four cases). Pyelonephritis, lymphoma, and metastases were considered in the differential diagnosis. An ill-defined low-attenuation mass-like lesion was found in one patient, while diffuse thickening of the renal pelvis wall was evident in the last two cases. Renal lesions regressed in all patients after steroid treatment, the larger one leaving a fibrous cortical scar. Conclusion: Different types of renal lesions in patients with AIP are relatively common, appearing as multiple nodules with decreased enhancement. These findings support the proposed concept of an IgG4-related systemic disease. Autoimmune disease should be suspected in cases of renal involvement in association with pancreatic focal or diffuse enlargement.

    1979-01-01

    Stone in the urinary tract has fascinated the medical profession from the earliest times and has played an important part in the development of surgery. The earliest major planned operations were for the removal of vesical calculus; renal and ureteric calculi provided the first stimulus for the radiological investigation of the viscera, and the biochemical investigation of the causes of calculus formation has been the training ground for surgeons interested in metabolic disorders. It is therefore no surprise that stone has been the subject of a number of monographs by eminent urologists, but the rapid development of knowledge has made it possible for each one of these authors to produce something new. There is still a technical challenge to the surgeon in the removal of renal calculi, and on this topic we are always glad to have the advice of a master craftsman; but inevitably much of the interest centres on the elucidation of the causes of stone formation and its prevention. Professor Pyrah has had a long an...

    During clinical gait analysis, surface markers are placed over the anterior superior iliac spines (ASIS) of the pelvis. However, this can be problematic in overweight or obese subjects, where excessive adipose tissue can obscure the markers and prevent accurate tracking. A novel solution to this problem has previously been proposed and tested on a limited sample of healthy, adult subjects. This involves use of wand markers on the pelvis, to virtually recreate the ASIS markers. The method was tested here on 20 typical subjects presenting for clinical gait analysis (adults and children, including overweight subjects). The method was found to accurately reproduce ASIS markers, and allow calculation of pelvic angles to within one degree of angles produced by ASIS markers. Copyright © 2013 Elsevier B.V.

    2012-01-01

    Full Text Available The osseous pelvis is a well-recognized site of origin of numerous primary and secondary musculoskeletal tumors. The radiologic evaluation of a pelvic lesion often begins with the plain film and proceeds to computed tomography (CT, or magnetic resonance imaging (MRI and possibly biopsy. Each of these modalities, with inherent advantages and disadvantages, has a role in the workup of pelvic osseous masses. Clinical history and imaging characteristics can significantly narrow the broad differential diagnosis for osseous pelvic lesions. The purpose of this review is to familiarize the radiologist with the presentation and appearance of some of the common benign neoplasms of the osseous pelvis and share our experience and approach in diagnosing these lesions.

    The interaction between the sagittal alignment of the spine and pelvis and the compensatory mechanism in patients suffering from spinal disorders has been well documented. However, in patients with hip osteoarthritis (HOA), few studies have explored how the hip joint pathology could affect the sagittal alignment of the hip, pelvis and spine, and no reports have investigated whether these changes are involved in the pathogenesis of low back pain in these patients. The aims of this case-control study were to investigate the sagittal spine-pelvis-leg alignment in patients suffering from severe HOA and to understand whether the alignment was related to the occurrence of low back pain and the health-related quality of life in these patients. Fifty-eight patients with severe HOA and 64 asymptomatic controls were studied. Digital lateral X-rays of the spine, pelvis and proximal femur were obtained with the patients placed in upright positions. The following radiographic parameters were measured to examine the sagittal alignment of the pelvis, hip and spine: pelvic incidence (PI), pelvic tilting (PT), sacral slope (SS), pelvic femoral angle (PFA), femoral inclination (FI), lumbar lordosis (LL), spino-sacral angle (SSA), C7 tilt (C7T) and T1 spinal-pelvic inclination (T1-SPI). The global balance patterns of spinal-pelvic alignment were classified as normal balance, slight unbalance and severe unbalance according to the relative position of the C7 plumb line to the sacrum and femoral heads. Short Form-36 questionnaire was carried out in the patients. Comparisons were carried out between the patients with HOA and the controls and between the HOA patients with or without low back pain. Correlation analysis was used to measure relationships between the HOA patients' parameters. There were no significant differences in the age and gender distribution between the HOA patients and control. Compared with the controls, the patients with HOA showed significantly higher SS and lower

    This study aimed to investigate testicular dose (TD) and the associated risk of heritable disease from common pelvis radiotherapy of male patients in Iran. In this work, the relation between TD and changes in beam energy, pelvis size, source to skin distance (SSD) and beam directions (anterior or posterior) was also evaluated. The values of TDs were measured on 67 randomly selected male patients during common pelvis radiotherapy using 1.17 and 1.33 MeV, Theratron Cobalt-60 unit at SSD of 80 cm and 9 MV, Neptun 10 PC and 18 MV, GE Saturne 20 at SSD of 100 cm at Seyed-Al Shohada Hospital, Isfahan, Iran. Results showed that, the maximum TD was up to 12% of the tumor dose. Considering the risk factor for radiation-induced heritable disorders of 0.1% per Sv, an excess risk of hereditary disorders of 72 per 10,000 births was conservatively calculated. There was a significant difference in the measured TD using different treatment machines and energies (P pelvis size (r = 0.275, P < 0.001). Using the student's t-tests, it was found that, there was not a significant difference between TD and beam direction (P = 0.231). Iranian male patients undergoing pelvic radiotherapy have the potential of receiving a TD of more than 1 Gy which might result in temporary azoospermia. The risk for induction of hereditary disorders in future generations should be considered as low but not negligible in comparison with the correspondent nominal risk.

    People with unilateral, transtibial amputation (TTA) have an increased prevalence of chronic low back pain (LBP) relative to able-bodied people. However, a definitive cause of increased LBP susceptibility has not been determined. The purpose of this work was to compare dynamic trunk-pelvis biomechanics between people with (n=6) and without (n=6) unilateral TTA during walking using a computational modeling approach. A generic, muscle-actuated whole body model was scaled to each participant, and experimental walking data were used in a static optimization framework to calculate trunk-pelvis motion, L4L5 joint contact forces, and muscle forces within the trunk-pelvis region. Results included several significant between-group differences in trunk-pelvis biomechanics during different phases of the gait cycle. Most significant was greater lateral bending toward the residual side during residual single-limb stance (p<0.01), concurrent with an elevated L4L5 joint contact force (p=0.02) and greater muscle force from the intact-side obliques (p<0.01) in people with TTA relative to able-bodied people. During both double-limb support phases, people with TTA also had a greater range of axial trunk rotation away from the leading limb, concurrent with greater ranges of muscle forces in the erector spinae and obliques. In addition, a greater range of force (p=0.03) in residual-side psoas was found during early residual limb swing in people with TTA. Repeated exposure to atypical motion and joint/muscle loading in people with TTA may contribute to the development of secondary musculoskeletal disorders, including chronic, mechanical LBP.

  7. Selective pressures in the human bony pelvis: Decoupling sexual dimorphism in the anterior and posterior spaces.

    Science.gov (United States)

    Brown, Kirsten M

    2015-07-01

    Sexual dimorphism in the human bony pelvis is commonly assumed to be related to the intensity of obstetrical selective pressures. With intense obstetrical selective pressures, there should be greater shape dimorphism; with minimal obstetrical selective pressures, there should be reduced shape dimorphism. This pattern is seen in the nondimorphic anterior spaces and highly dimorphic posterior spaces. Decoupling sexual dimorphism in these spaces may in turn be related to the differential influence of other selective pressures, such as biomechanical ones. The relationship between sexual dimorphism and selective pressures in the human pelvis was examined using five skeletal samples (total female n = 101; male n = 103). Pelvic shape was quantified by collecting landmark coordinate data on articulated pelves. Euclidean distance matrix analysis was used to extract the distances that defined the anterior and posterior pelvic spaces. Sex and body mass were used as proxies for obstetrical and biomechanical selective pressures, respectively. MANCOVA analyses demonstrate significant effects of sex and body mass on distances in both the anterior and the posterior spaces. A comparison of the relative contribution of shape variance attributed to each of these factors suggests that the posterior space is more influenced by sex, and obstetrics by proxy, whereas the anterior space is more influenced by body mass, and biomechanics by proxy. Although the overall shape of the pelvis has been influenced by obstetrical and biomechanical selective pressures, there is a differential response within the pelvis to these factors. These results provide new insight into the ongoing debate on the obstetrical dilemma hypothesis. © 2015 Wiley Periodicals, Inc.

    2015-12-01

    Full Text Available Diagnosis of ankylosing spondylitis is based on characteristic clinical picture of the disease and mandatory identification of sacroiliitis on pelvis X-ray. However, case reports of the radiographic stages of sacroiliac joint disorder available in literature are less informative and often lead to misinterpretation of radiographic changes. Based on many years of experience, the authors present the extended explanations of standard radiographic stages of sacroiliitis and other radiological signs that can facilitate diagnostic search in ankylosing spondylitis.

    Full Text Available The orthopedic and x-ray studies of children of different ages with combined diseases of the spine and pelvis, living under constant effects of the harmful production factors induced by the aluminium production of Irkutsk region, have been conducted. The priority factor of exogenous risk to health is fluoride compounds. It has been established that in the structure of the combined pathology, the pelvis asymmetry ranks first, scoliosis ranks second, Legg – Calve – Perthes disease ranks third. According to the assessment of age structure of combined pathology we can conclude that at the equal manifestations of scoliosis, Spina bifida, retrospondylolisthesis, pelvis asymmetry, children of 11–15 y.o. more often have Legg – Calve – Perthes disease, children of 16–21 y.o. – coxarthrosis. We established statistically significant correlation between Legg – Calve – Perthes disease and age and sex of the children (Pearson's χ 2 at p < 0.01 makes 15.821 and 21.228 correspondingly. It’s important to mention that Legg – Calve – Perthes disease was registered in all examined boys and only in 35.5 % of girls. Correlation between this pathology and ecological factors was also statistically proved (χ 2 = 5.264, p < 0.05: within the radius of 5 km from the production facility the proportion of avascular necrosis was the highest (75 % cases. I and II degrees of manifestation of clinicoroentgenologic disorders of combined spine and pelvis pathology prevail. The relevance of further search for evidence of the relationship of chemical risk factors and the development of diseases of the musculoskeletal system was determined. Regular medical follow-up monitoring of children living in ecologically unfavorable territories in terms of early diagnosis of combined orthopedic pathology is recommended, including its premorbid period of development.

    1989-01-01

    The occurrence and significance of bacterial carbohydrate recognition proteins (bacterial lectins) and endogenous carbohydrate binding proteins (endogenous lectins) of human urothelium as well as kidney tubulus epithelium was analyzed with respect to the adhesion of urotoxogenic Escherichia coli bacteria. Using biotinylated neoglycoproteins, we demonstrated a wide spectrum of endogenous lectins with Galactose-, Mannose-, Fucose-, N-Acetylgalactosamine-, and N-Acetylglucosamine binding activities in the urothelium. In the kidney the distal nephron and especially the medullar collecting ducts exhibited a similar spectrum of endogenous carbohydrate binding activities as detected for the urothelium. Adhesion- as well as inhibition-experiments with selective blocking of either bacterial lectins or endogenous lectins of the target cells by different carbohydrates both reduced the bacterial adhesion. However, maximal inhibition of bacterial adhesion was achieved by simultanous blocking of microbial and target cell lectins with mannose or mannan. From these results it is reasonable to conclude that specific adhesion which may result in an organotropism (urotropism) of E. coli infection is due to a dual recognition mechanism which is accomplished by the combined interaction of the bachterial and host cell lectins with the corresponding carbohydrates of E. coli and that of the target cells respectively. Further studies showed that normal human serum possesses natural antiadhesins which are represented by the glycan parts of the serum-glycoproteins.

    To determine the feasibility of time-resolved dynamic contrast-enhanced magnetic resonance urography (MRU) for the evaluation of ureteral peristalsis using a data-sharing 3D gradient echo sequence with spiral k-space filling. Eight patients (M=3, F=5, mean 48.1 years) were referred for MRU for the evaluation for renal mass (n=3), hematuria (n=2), urinary tract tuberculosis (n=1), postoperative bladder cancer (n=1), and postoperative ureteric reimplantation (n=1). Dynamic MRU was performed for 120 seconds at 1.5T after intravenous furosemide and gadolinium administration using an oblique sagittal, time-resolved T1 3D gradient echo sequence with 1 second effective temporal resolution. Study quality was assessed based on artifacts and extent of ureteric visualization. Frequency of peristalsis from the renal pelvis to urinary bladder was evaluated for each subject. A total of 16 ureters were examined. Image quality was good in four ureters, satisfactory in 11 ureters, and poor in one ureter. Mean peristaltic frequency was 3.5 waves per minute (range, 2.5-6.5 waves/minute) in normal ureters (n=11). Five ureters were considered abnormal (one urinary tract tuberculosis and four postsurgical ureters), and all had decreased or no peristalsis (0-1.5 waves per minute). MRU using a time-resolved, data-sharing 3D contrast-enhanced technique is able to demonstrate ureteral peristalsis and permits quantification of ureteral peristaltic frequency.

  15. The evolution, development and skeletal identity of the crocodylian pelvis: revisiting a forgotten scientific debate.

    Science.gov (United States)

    Claessens, Leon P A M; Vickaryous, Matthew K

    2012-10-01

    Unlike most tetrapods, in extant crocodylians the acetabulum is formed by only two of the three skeletal elements that constitute the pelvis, the ilium, and ischium. This peculiar arrangement is further confused by various observations that suggest the crocodylian pelvis initially develops from four skeletal elements: the ilium, ischium, pubis, and a novel element, the prepubis. According to one popular historical hypothesis, in crocodylians (and many extinct archosaurs), the pubis fuses with the ischium during skeletogenesis, leaving the prepubis as a distinct element, albeit one which is excluded from the acetabulum. Whereas the notion of a distinct prepubic element was once a topic of considerable interest, it has never been properly resolved. Here, we combine data gleaned from a developmental series of Alligator mississippiensis embryos, with a revised interpretation of fossil evidence from numerous outgroups to Crocodylia. We demonstrate that the modern crocodylian pelvis is composed of only three elements: the ilium, ischium, and pubis. The reported fourth pelvic element is an unossified portion of the ischium. Interpretations of pelvic skeletal homology have featured prominently in sauropsid systematics, and the unambiguous identification of the crocodylian pubis provides an important contribution to address larger scale evolutionary questions associated with locomotion and respiration.

    Robust generation of pelvic finite element models is necessary to understand variation in mechanical behaviour resulting from differences in gender, aging, disease and injury. The objective of this study was to apply and evaluate mesh morphing and mapping techniques to facilitate the creation and structural analysis of specimen-specific finite element (FE) models of the pelvis. A specimen-specific pelvic FE model (source mesh) was generated following a traditional user-intensive meshing scheme. The source mesh was morphed onto a computed tomography scan generated target surface of a second pelvis using a landmarked-based approach, in which exterior source nodes were shifted to target surface vertices, while constrained along a normal. A second copy of the morphed model was further refined through mesh mapping, in which surface nodes of the initial morphed model were selected in patches and remapped onto the surfaces of the target model. Computed tomography intensity-based material properties were assigned to each model. The source, target, morphed and mapped models were analyzed under axial compression using linear static FE analysis, and their strain distributions were evaluated. Morphing and mapping techniques were effectively applied to generate good quality and geometrically complex specimen-specific pelvic FE models. Mapping significantly improved strain concurrence with the target pelvis FE model.

    Gorham-Stout disease (GSD) is a rare condition characterized by spontaneous idiopathic bone resorption that can affect any part of the skeleton. Treatment is aimed at halting osteolysis and alleviating complications associated with bone loss. Often this can be achieved via observation and supportive management, medical treatment, and/or radiation therapy. We report a case of GSD of the pelvis that was refractory to medical and radiation therapy and was managed successfully with surgery. A 30-year-old man presented to our clinic 3 years after being diagnosed at an outside institution with GSD of the pelvis that was managed with medical treatments and radiation therapy. Despite aggressive, multimodality treatment, he was unable to ambulate without crutches and was in significant pain. The patient opted for intralesional surgery and spinopelvic fusion. Sixteen months after surgery, the patient had only mild pain and was able to ambulate with a cane. Very few cases have been reported of GSD involving the pelvis that necessitated surgical management. Significant functional impairment can occur as a result of pelvic osteolysis, and traditional management strategies focused on halting resorption may not be adequate. Surgical stabilization of the affected areas is an important treatment strategy for patients who have exhausted other options.

    [Purpose] The purpose of this study was to evaluate the changes in body stability of the elderly while walking on even surface ground under low light. [Subjects] Ten young males and ten elderly males participated in this experiment. [Methods] Each subject walked along a 7 m walkway five times at their preferred walking speed under normal (>300 lux, NORM) and low light conditions (LOW). To compare the changes in body stability, the root mean square of acceleration (RMSacc) at the head and pelvis was used. [Results] The results show that the body stability of young adults showed a similar RMSacc in all directions at the head and pelvis between the normal and low light walking conditions. In contrast, the RMSacc in all directions at the head and pelvis during low light walking by elderly adults was significantly greater than that of normal light walking. [Conclusion] It was confirmed that, despite walking on even ground, low light condition affects the body stability of the elderly. To clearly evaluate the effect of low light with aging on gait pattern, further study will be necessary to perform additional experiments under various environmental conditions to investigate walking speed, multi-tasking, stairs, and uneven walkway performance.

    Acute hip pain following total hip arthroplasty (THA) could have numerous causes to include stress fracture of the pelvis. Stress fractures of the pelvis are rare and have been reported to involve the medial wall and the pubic ramus. A unique case is presented demonstrating the clinical presentation and management of an acute stress fracture of ilium and anterior column following a THA. A 72-year-old man underwent an uncomplicated right THA. He was noted to have femoral head resorption and thin osteoporotic bone intraoperatively. He initially did well postoperatively and ambulating without pain or assistive devices. Within 1 month of surgery, he returned with acute right hip pain without any traumatic event. Radiographs showed migration of the acetabular component and computed tomography scan confirmed a fracture through the ilium. The patient underwent revision surgery, where the fracture was reduced and internal fixation was achieved with a reconstruction plate and acetabular cage construct. At 9 months postoperatively, the patient remained pain-free with full weight bearing and with stable radiographs. Elderly patients who undergo THA may have low bone mineral density. These patients can develop stress fractures in their pelvis after surgery. These fractures may involve the medial wall, posterior column, or posterior wall. In patients who develop atraumatic pain postoperatively, it is important to consider for potential stress fractures of the ilium and evaluate appropriately with imaging. In these cases, revision surgery can be necessary to provide fixation of the stress fracture.

    Full Text Available A agenesia renal é uma afecção congênita rara na espécie felina, frequentemente associada a uma malformação reprodutiva. O presente trabalho relata o caso de um felino com agenesia renal unilateral associada a criptorquidismo ipsilateral, com ênfase no diagnóstico, tratamento e acompanhamento. O paciente foi conduzido ao Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul para avaliação de criptorquidismo. A agenesia renal foi um achado durante a ecografia abdominal do felino. Durante a laparotomia, foi confirmada a ausência do rim e ureter direito, hipertrofia do rim esquerdo e presença de um testículo ectópico. O paciente teve alta após a recuperação anestésica e se mantém clinicamente estável, transcorridos seis meses da cirurgia. A agenesia renal unilateral é uma condição compatível com a vida, contanto que o rim existente apresente funcionamento aceitável. Assim, sugere-se que a possibilidade de rim único em felinos criptorquidas deve ser investigada sempre que possível, tendo em vista a alta correlação entre essas malformações, e objetivando um acompanhamento da função renal do paciente ao longo da vida.

    In walking faster than 3 km/h, transverse pelvic rotation lengthens the step ("pelvic step"). It is often assumed that the thorax then starts to counter rotate to limit total body angular momentum around the vertical. But the relative timing of pelvis and thorax rotation during gait is insufficiently understood. The present study aimed at analysing how transverse pelvis and thorax rotations relate to the movements of the upper leg, and how these patterns contribute to total body angular momentum. Nine healthy male volunteers walked on a treadmill at nine different velocities, ranging from 2.0 km/h to 5.2 km/h. Full body kinematics were recorded. Femur-pelvis, pelvis-thorax, and femur-thorax relative phase were calculated, as well as transverse plane angular momentum of all body segments. The shift in pelvis-thorax coordination from in-phase to out of phase with increasing velocity was found to depend on the pelvis beginning to move in-phase with the femur, while the thorax continued to counter rotate with respect to the femur. Moreover, pelvic and thoracic contributions to total body angular momentum were low (less than 10%), while contributions of the legs and arms were much larger (approximately 90%), suggesting that pelvis-thorax coordination is relatively unimportant to the organisation of total body angular momentum. Taken together, these results may imply that our understanding of the pelvic step need to be changed. Moreover, the alterations in pelvis-thorax relative phase that were reported for different locomotor pathologies may depend on different mechanisms.

    Renal actinomycosis is a rare infection caused by fungi of the genus Actinomyces. A 74-year-old male was admitted to our hospital because of gross hematuria with urinary symptoms and intermittent chills. Computed tomography of the abdomen showed thrombosis in the left renal vein and diffuse, heterogeneous enlargement of the left kidney. After nephrectomy, sulfur granules with chronic suppurative inflammation were seen microscopically, and the histopathological diagnosis was renal actinomycosis. Our case is the first report of renal actinomycosis with renal vein thrombosis.

    Primary adenocarcinoma of the urinary bladder is a rare neoplasm. It accounts for 1-2% of all bladder carcinomas and sometimes may be found in the bladder diverticula. Fistula between duodenum and renal pelvis is another rarity while colovesical fistula is not so uncommon. We present a case of a 40 years old man who had surgery for colovesical and duodenorenal fistula and subsequently developed adenocarcinoma of the urinary bladder.

    Little attention has been devoted to the thorax and pelvis movements during gait. The aim of this study is to compare differences in the thorax and pelvis kinematics during unassisted walking on a treadmill and during walking with robot assistance (Lokomat-system (Hocoma, Volketswil, Switzerland)). 18 healthy persons walked on a treadmill with and without the Lokomat system at 2kmph. Three different conditions of guidance force (30%, 60% and 100%) were used during robot-assisted treadmill walking (30% body weight support). The maximal movement amplitudes of the thorax and pelvis were measured (Polhemus Liberty™ (Polhemus, Colchester, Vermont, USA) (240/16)). A repeated measurement ANOVA was conducted. Robot-assisted treadmill walking with different levels of guidance force showed significantly smaller maximal movement amplitudes for thorax and pelvis, compared to treadmill walking. Only the antero-posterior tilting of the pelvis was significantly increased during robot-assisted treadmill walking compared to treadmill walking. No significant changes of kinematic parameters were found between the different levels of guidance force. With regard to the thorax and pelvis movements, robot-assisted treadmill walking is significantly different compared to treadmill walking. It can be concluded that when using robot assistance, the thorax is stimulated in a different way than during walking without robot assistance, influencing the balance training during gait.

  8. miR-200b precursor can ameliorate renal tubulointerstitial fibrosis.

    Directory of Open Access Journals (Sweden)

    Shigeyoshi Oba

    Full Text Available Members of the miR-200 family of micro RNAs (miRNAs have been shown to inhibit epithelial-mesenchymal transition (EMT. EMT of tubular epithelial cells is the mechanism by which renal fibroblasts are generated. Here we show that miR-200 family members inhibit transforming growth factor-beta (TGF-beta-induced EMT of tubular cells. Unilateral ureter obstruction (UUO is a common model of EMT of tubular cells and subsequent tubulointerstitial fibrosis. In order to examine the role of miR-200 family members in tubulointerstitial fibrosis, their expression was investigated in the kidneys of UUO mice. The expression of miR-200 family miRNAs was increased in a time-dependent manner, with induction of miR-200b most pronounced. To clarify the effect of miR-200b on tubulointerstitial fibrosis, we injected miR-200b precursor intravenously. A single injection of 0.5 nM miR-200b precursor was sufficient to inhibit the increase of collagen types I, III and fibronectin in obstructed kidneys, and amelioration of fibrosis was confirmed by observation of the kidneys with Azan staining. miR-200 family members have been previously shown to inhibit EMT by reducing the expression of ZEB-1 and ZEB-2 which are known repressors of E-cadherin. We demonstrated that expression of ZEB-1 and ZEB-2 was increased after ureter obstruction and that administration of the miR-200b precursor reversed this effect. In summary, these results indicate that miR-200 family is up-regulated after ureter obstruction, miR-200b being strongly induced, and that miR-200b ameliorates tubulointerstitial fibrosis in obstructed kidneys. We suggest that members of the miR-200 family, and miR-200b specifically, might constitute novel therapeutic targets in kidney disease.

  10. Role of TREM1-DAP12 in renal inflammation during obstructive nephropathy.

    Directory of Open Access Journals (Sweden)

    Alessandra Tammaro

    Full Text Available Tubulo-interstitial damage is a common finding in the chronically diseased kidney and is characterized by ongoing inflammation and fibrosis leading to renal dysfunction and end-stage renal disease. Upon kidney injury, endogenous ligands can be released which are recognized by innate immune sensors to alarm innate immune system. A new family of innate sensors is the family of TREM (triggering receptor expressed on myeloid cell. TREM1 is an activating receptor and requires association with transmembrane adapter molecule DAP12 (DNAX-associated protein 12 for cell signaling. TREM1-DAP12 pathway has a cross-talk with intracellular signaling pathways of several Toll-like receptors (TLRs and is able to amplify TLR signaling and thereby contributes to the magnitude of inflammation. So far, several studies have shown that TLRs play a role in obstructive nephropathy but the contribution of TREM1-DAP12 herein is unknown. Therefore, we studied TREM1 expression in human and murine progressive renal diseases and further investigated the role for TREM1-DAP12 by subjecting wild-type (WT, TREM1/3 double KO and DAP12 KO mice to murine unilateral ureter obstruction (UUO model. In patients with hydronephrosis, TREM1 positive cells were observed in renal tissue. We showed that in kidneys from WT mice, DAP12 mRNA and TREM1 mRNA and protein levels were elevated upon UUO. Compared to WT mice, DAP12 KO mice displayed less renal MCP-1, KC and TGF-β1 levels and less influx of macrophages during progression of UUO, whereas TREM1/3 double KO mice displayed less renal MCP-1 level. Renal fibrosis was comparable in WT, TREM1/3 double KO and DAP12 KO mice. We conclude that DAP12, partly through TREM1/3, is involved in renal inflammation during progression of UUO.

In addition, it can be used in premature infants. ESWL is used to treat kidney and ureter stones in children. However, although it is a preferred noninvasive treatment in that setting, there is debate about its long-term effects on growing kidneys in children.Objectives: To investigate the long-term effects of pediatric ESWL on renal function in light of updated literature.Methods: PubMed and Medline were searched for studies on ESWL in a pediatric population with keywords including efficacy, child, kidney calculi, ureter calculi, lithotripsy, injury, vascular trauma, and shock waves. The research was limited to the English literature during a period from 1980 to 2014. In total, 3,000 articles were evaluated, but only 151 papers were considered. Only the manuscripts directly related to the reviewed subjects were included in the current study.Results: However, the acute effects of ESWL in kidney are well-described. Although there are limited studies on the long-term effects of ESWL in children, there is a widespread opinion that ESWL is not affecting renal functions in the long-term.Conclusion: ESWL is a safe, effective, and noninvasive treatment option in children. Although ESWL can cause some acute effects in the kidney, there is no long-term effect on the growing kidneys of children.Keywords: child, lithotripsy, nephrolithiasis, renal injury, vascular trauma

SPECT/CT revealed a focal uptake in the pelvis, corresponding to hypoplastic kidney as confirmed by MRI. Based on SPECT/CT findings, the patient underwent laparoscopic surgery, using Tc-DMSA scan to help the surgeon to detect the small ectopic kidney. Intraoperatory histological report confirmed the renal origin of the specimen.

  13. Optimal Skin-to-Stone Distance Is a Positive Predictor for Successful Outcomes in Upper Ureter Calculi following Extracorporeal Shock Wave Lithotripsy: A Bayesian Model Averaging Approach.

    Kang Su Cho

    Full Text Available To investigate whether skin-to-stone distance (SSD, which remains controversial in patients with ureter stones, can be a predicting factor for one session success following extracorporeal shock wave lithotripsy (ESWL in patients with upper ureter stones.We retrospectively reviewed the medical records of 1,519 patients who underwent their first ESWL between January 2005 and December 2013. Among these patients, 492 had upper ureter stones that measured 4-20 mm and were eligible for our analyses. Maximal stone length, mean stone density (HU, and SSD were determined on pretreatment non-contrast computed tomography (NCCT. For subgroup analyses, patients were divided into four groups. Group 1 consisted of patients with SSD<25th percentile, group 2 consisted of patients with SSD in the 25th to 50th percentile, group 3 patients had SSD in the 50th to 75th percentile, and group 4 patients had SSD≥75th percentile.In analyses of group 2 patients versus others, there were no statistical differences in mean age, stone length and density. However, the one session success rate in group 2 was higher than other groups (77.9% vs. 67.0%; P = 0.032. The multivariate logistic regression model revealed that shorter stone length, lower stone density, and the group 2 SSD were positive predictors for successful outcomes in ESWL. Using the Bayesian model-averaging approach, longer stone length, lower stone density, and group 2 SSD can be also positive predictors for successful outcomes following ESWL.Our data indicate that a group 2 SSD of approximately 10 cm is a positive predictor for success following ESWL.

  14. Different coordination and flexibility of the spine and pelvis during lateral bending between young and older adults.

    Sung, Paul S

    2016-04-01

    This study examined coordination of the spine and pelvis during lateral bending of the trunk in older adults. Thirty-four healthy subjects (17 young and 17 older adults) demonstrated lateral bending at a controlled speed while holding a bar at approximately 180 degrees of shoulder flexion. Kinematic data collection was completed on the thoracic spine, lumbar spine, and pelvis. The coupling angle was calculated to examine the thorax-lumbar, lumbar-pelvis, and thorax-pelvis coordination patterns. The older adults demonstrated a reduced range of motion (ROM) of the lumbar spine, while both groups revealed similar ROM in the thorax and in the pelvis. The coupling angle between the straightening and bending phases was different only for the older adults in the thorax-lumbar (23.4±8.0 vs. -1.6±4.4, p=0.004) and the lumbar-pelvis (65.4±7.2 vs. 86.1±7.8, p=0.001) coordination. However, there was no group difference in the thorax-pelvis coordination. These findings indicate that age-related changes in the lumbar region affect coordination patterns only during the bending phase. The older adults preserved a similar pattern of movement to the young adults during the straightening phase, but the coordination variability of the coupling angles was greater for the older adults than for the young adults. This movement pattern suggests that the older adults lacked consistent trunk control in an attempt to optimize lateral bending coordination.

    Full Text Available Introduction: Body posture is an individual motion habit. It is variable and depends on the gender, age, structure of the body but also on mental and physical state. Although it is difficult to formulate a universal definition of correct body posture, the opinion that its elementary feature is symmetry is beyond any doubt. Such symmetry is related to the position of particular anatomical points and effects of static and dynamic forces. Aim of the research: To assess the relations between the pelvis position in the frontal plane, the static load on the lower limbs and architecture of the feet. The following features were analysed in a group of young, healthy and particularly physically active women and men: the frequency of asymmetry related to pelvis position, the load on the lower limbs related to body weight and foot architecture. Material and methods: The study group consisted of 100 students of physical education. To assess the position of the pelvis a palpable-visual method was used. Clarke’s method was applied to characterize the foot architecture determined by the position of standing with one leg on the CQ Elektronik podoscope. The static load on the lower limbs was assessed using the stabilographic platform EMILDUE from Technomex. Results : Collected data and observations show frequent asymmetric changes of pelvis position in the frontal plane and incorrect balance of the body in the standing position. The change of static load on the lower limbs influences the longitudinal architecture of the feet and this influence is statistically significant. Increased asymmetry of the pelvis in the frontal plane is related to profound disorder of body balance. Conclusions : Asymmetric position of the pelvis is associated with asymmetric arching of the feet and asymmetric body weight distribution. Full symmetric position of the pelvis is rare even among young people who are physically active.

  16. Pelvis morphology, trunk posture and standing imbalance and their relations to the Cobb angle in moderate and severe untreated AIS.

    Directory of Open Access Journals (Sweden)

    Georges Dalleau

    Full Text Available Adolescent idiopathic scoliosis (AIS is the most common form of scoliosis and usually affects young girls. Studies mostly describe the differences between scoliotic and non-scoliotic girls and focus primarily on a single set of parameters derived from spinal and pelvis morphology, posture or standing imbalance. No study addressed all these three biomechanical aspects simultaneously in pre-braced AIS girls of different scoliosis severity but with similar curve type and their interaction with scoliosis progression. The first objective of this study was to test if there are differences in these parameters between pre-braced AIS girls with a right thoracic scoliosis of moderate (less than 27° and severe (more than 27° deformity. The second objective was to identify which of these parameters are related to the Cobb angle progression either individually or in combination of thereof. Forty-five scoliotic girls, randomly selected by an orthopedic surgeon from the hospital scoliosis clinic, participated in this study. Parameters related to pelvis morphology, pelvis orientation, trunk posture and quiet standing balance were measured. Generally moderate pre-brace idiopathic scoliosis patients displayed lower values than the severe group characterized by a Cobb angle greater than 27°. Only pelvis morphology and trunk posture were statistically different between the groups while pelvis orientation and standing imbalance were similar in both groups. Statistically significant Pearson coefficients of correlation between individual parameters and Cobb angle ranged between 0.32 and 0.53. Collectively trunk posture, pelvis morphology and standing balance parameters are correlated with Cobb angle at 0.82. The results suggest that spinal deformity progression is not only a question of trunk morphology distortion by itself but is also related to pelvis asymmetrical bone growth and standing neuromuscular imbalance.

  17. The effects of virtual reality game training on trunk to pelvis coupling in a child with cerebral palsy

    2013-02-01

    Full Text Available Abstract Background Good control of trunk and pelvic movements is necessary for well controlled leg movements required to perform activities of daily living. The nature of movement coupling between the trunk and pelvis varies and depends on the type of activity. Children with cerebral palsy often have reduced ability to modulate coupling between the trunk and pelvis but movement patterns of the pelvis can be improved by training. The aim of this study was to examine how pelvis to trunk coupling changed while playing a computer game driven by pelvic rotations. Methods One boy with cerebral palsy diplegia played the Goblin Post Office game on the CAREN virtual rehabilitation system for six weeks. He navigated a flying dragon in a virtual cave towards randomly appearing targets by rotating the pelvis around a vertical axis. Motion of the pelvis and trunk was captured in real-time by a Vicon 612 optoelectronic system tracking two clusters of three markers attached to the sacrum and thoracic spine. Results Convex hull areas calculated from angle-angle plots of pelvic and trunk rotations showed that coupling increased over game training (F1,11 = 7.482, p = 0.019. Reaching to targets far from the midline required tighter coupling than reaching near targets (F1,12 = 10.619, p = 0.007. Conclusions Increasing coupling appears to be an initial compensation mechanism using the better controlled trunk to drive rotation of the pelvis. Co-contractions causing increased coupling are expected to reduce over longer exposure to training. The control scheme of the training game can be set to facilitate de-coupling of pelvic movements from the trunk. Using large ranges of pelvic rotation required more coupling suggesting that training of selective pelvic movements is likely to be more effective close to a neutral pelvic posture.

    We report on the first case of acute renal failure related to obstructive urinary tract lithiasis involving sulfadiazine crystals in a kidney transplant recipient. This patient had disseminated toxoplasmosis which was treated by sulfadiazine (4 g/day) and pyrimethamine (50 mg/day). In the fourth week of anti-toxoplasmosis therapy, he presented with obstructive acute renal failure: the plasma creatinine level increased from 220 micromol/l to 547 micromol/l. Apercutaneous pyelography was conducted showing the presence of a lithiasis located at the junction between the graft ureter and the bladder. Six days later, he underwent surgery to retrieve an orange-colored, friable stone. Its spectrophotometric analysis confirmed that the stone consisted of N-acetyl sulfadiazine crystals.
