    The non-specific symptoms the patients express upon the presentation of female bladder outlet obstruction make it a challenge to diagnose. There are subtle differences between the obstructed patient and those whose bladders are underactive and/or fail to mount a detrusor contraction. These disparities can be extracted through a thorough history and examination. At times, the clinician may utilize nomograms, non-invasive uroflow, and urodynamics with the addition of fluoroscopy to establish the diagnosis of obstruction. Management of the obstruction depends on the nature of the condition, whether functional or anatomical. The increase in the number of sling procedures performed to treat stress urinary incontinence has resulted in a rise in the number of iatrogenic obstructions. The temporal relationship between surgery and obstruction is the key to identifying the problem. PMID:26902625

    Mild bladder outlet obstruction was created in 42 New Zealand white rabbits by placing a 5-mm inner diameter polyethylene tube around the urethra. Periods of obstruction lasted for 1 day (7 rabbits), 3 days (7 rabbits), 1 week (7 rabbits), 2 weeks (6 rabbits), 4 weeks (7 rabbits), 6 weeks (4 rabbits) and 8 weeks (4 rabbits). Whole bladder functional study was performed in control (5 rabbits) and the obstructed bladders. The obstructed bladders increased in weight two-to threefold. There was no significant difference in bladder weight after different periods of obstruction. Electric stimulation showed a diminished response after 3 days of obstruction. Pharmacologic stimulation with 500 microM carbachol revealed a decreased response after obstruction, but intravesical pressure returned to the control level at 6 and 8 weeks of obstruction. However, the bladder weight and the expelling function of the obstructed bladders remained the same as on day 1 of obstruction. Histologic study of control and obstructed bladders revealed that: 1) dense submucosal fibrous tissue developed after 3 days of obstruction, 2) detrusor muscle hypertrophy and hyperplasia were noted with intermuscular collagenous fiber deposition after 2 weeks of obstruction, 3) trabeculation of the bladder wall with hyperplasia of muscular bundles was noted after 2 weeks of obstruction, 4) acute edematous and inflammatory reaction were apparent after 3 days and 1 week of obstruction, but resolved later and 5) degenerative changes of muscular cells were noted at 8 weeks of obstruction. The results show that despite apparent morphologic changes after outlet obstruction, no significant difference was observed in bladder expelling between short-term and long-term infravesical mild outlet obstruction. The bladder contractile apparatus appears to have a compensatory ability after mild outlet obstruction. PMID:8696170

    A 12-year-old boy presented with poor flow and recurrent urinary tract infections following hypospadias repair at the age of 3 years. The evaluation revealed urethral duplication with a hypoplastic dorsal urethra and patent ventral urethra. He also had duplication of the bladder neck, and on voiding cystourethrogram the ventral bladder neck appeared hypoplastic and compressed by the dorsal bladder neck during voiding. The possibility of functional obstruction of the ventral urethra by the occluded dorsal urethra was suspected, and he underwent a successful urethro-urethrostomy.

  5. Mir-29 repression in bladder outlet obstruction contributes to matrix remodeling and altered stiffness.

    Full Text Available Recent work has uncovered a role of the microRNA (miRNA miR-29 in remodeling of the extracellular matrix. Partial bladder outlet obstruction is a prevalent condition in older men with prostate enlargement that leads to matrix synthesis in the lower urinary tract and increases bladder stiffness. Here we tested the hypothesis that miR-29 is repressed in the bladder in outlet obstruction and that this has an impact on protein synthesis and matrix remodeling leading to increased bladder stiffness. c-Myc, NF-κB and SMAD3, all of which repress miR-29, were activated in the rat detrusor following partial bladder outlet obstruction but at different times. c-Myc and NF-κB activation occurred early after obstruction, and SMAD3 phosphorylation increased later, with a significant elevation at 6 weeks. c-Myc, NF-κB and SMAD3 activation, respectively, correlated with repression of miR-29b and miR-29c at 10 days of obstruction and with repression of miR-29c at 6 weeks. An mRNA microarray analysis showed that the reduction of miR-29 following outlet obstruction was associated with increased levels of miR-29 target mRNAs, including mRNAs for tropoelastin, the matricellular protein Sparc and collagen IV. Outlet obstruction increased protein levels of eight out of eight examined miR-29 targets, including tropoelastin and Sparc. Transfection of human bladder smooth muscle cells with antimiR-29c and miR-29c mimic caused reciprocal changes in target protein levels in vitro. Tamoxifen inducible and smooth muscle-specific deletion of Dicer in mice reduced miR-29 expression and increased tropoelastin and the thickness of the basal lamina surrounding smooth muscle cells in the bladder. It also increased detrusor stiffness independent of outlet obstruction. Taken together, our study supports a model where the combined repressive influences of c-Myc, NF-κB and SMAD3 reduce miR-29 in bladder outlet obstruction, and where the resulting drop in miR-29 contributes to

    We investigated the effects of partial bladder outlet obstruction (BOO) on the function and gene expression of 5-hydroxytryptamine (5-HT) receptor subtypes in rat bladder. Isometric contractions of the isolated bladders from sham-operated control and BOO rats were examined. The contractile responses to 5-HT were significantly increased in BOO rat bladder strips, while the responses to KCl, carbachol, or phenylephrine were not different from the control. The 5-HT-induced hypercontraction in BOO rat bladder strips was inhibited by ketanserin, a 5-HT(2A) receptor antagonist. The contractile responses to 5-HT in bladder strips were not affected by urothelium removal from the intact bladder. The gene expression of 5-HT receptor subtypes in the bladders was analyzed by RT-PCR. The mRNA expression of the 5-HT(2A), 5-HT(2B), 5-HT(2C), 5-HT(4), and 5-HT(7) receptors was detected in both the control and BOO rat bladders. Quantitative RT-PCR analysis showed there was a significant increase of 5-HT(2A) receptor mRNA in the BOO rat bladder compared with the control bladder. On the other hand, the gene expression of the 5-HT(4) receptor was not changed in the BOO rat bladder. These results suggest that the increased contractile responses to 5-HT in BOO rat bladder may be partly caused by 5-HT(2A) receptor upregulation in the detrusor smooth muscles. PMID:23344575

    The aim of the present study was to investigate the expression and distribution of membrane receptors after bladder outlet obstruction (BOO). Partial bladder outlet obstruction (BOO) was induced in female rats and bladders were harvested after either 10 days or 6 weeks of BOO. The expression of different receptors was surveyed by microarrays and corroborated by immunohistochemistry and western blotting. A microarray experiment identified 10 membrane receptors that were differentially expressed compared to sham-operated rats including both upregulated and downregulated receptors. Four of these were selected for functional experiments on the basis of magnitude of change and relevance to bladder physiology. At 6 weeks of BOO, maximal contraction was reduced for neuromedin B and vasopressin (AVP), consistent with reductions of receptor mRNA levels. Glycine receptor-induced contraction on the other hand was increased and receptor mRNA expression was accordingly upregulated. Maximal relaxation by the β3-adrenergic receptor agonist CL316243 was reduced as was the receptor mRNA level. Immunohistochemistry supported reduced expression of neuromedin B receptors, V1a receptors and β3-adrenergic receptors, but glycine receptor expression appeared unchanged. Western blotting confirmed repression of V1a receptors and induction of glycine receptors in BOO. mRNA for vasopressin was detectable in the bladder, suggesting local AVP production. We conclude that changes in receptor expression following bladder outlet obstruction are non-uniform. Some receptors are upregulated, conferring increased responsiveness to agonist, whereas others are downregulated, leading to decreased agonist-induced responses. This study might help to select pharmacological agents that are effective in modulating lower urinary tract symptoms in BOO. PMID:26004535

    Full Text Available Background: Work in voiding (WIV of the bladder may be used to evaluate bladder status throughout urination rather than at a single time point. Few studies, however, have assessed WIV owing to the complexity of its calculations. We have developed a method of calculating work capacity of the bladder while voiding and analyzed the associations of bladder work parameters with bladder contractile function and bladder outlet obstruction (BOO. Methods: The study retrospectively evaluated 160 men and 23 women, aged >40 years and with a detrusor pressure at maximal flow rate (P det Q max of ≥40 cmH 2 O in men, who underwent urodynamic testing. The bladder power integration method was used to calculate WIV; WIV per second (WIV/t and WIV per liter of urine voided (WIV/v were also calculated. In men, the relationships between these work capacity parameters and P det Q max and Abrams-Griffiths (AG number were determined using linear-by-linear association tests, and relationships between work capacity parameters and BOO grade were investigated using Spearman′s association test. Results: The mean WIV was 1.15 ± 0.78 J and 1.30 ± 0.88 J, mean WIV/t was 22.95 ± 14.45 mW and 23.78 ± 17.02 mW, and mean WIV/v was 5.59 ± 2.32 J/L and 2.83 ± 1.87 J/L in men and women, respectively. In men, WIV/v showed significant positive associations with P det Q max (r = 0.845, P = 0.000, AG number (r = 0.814, P = 0.000, and Schafer class (r = 0.726, P = 0.000. Conversely, WIV and WIV/t showed no associations with P det Q max or AG number. In patients with BOO (Schafer class > II, WIV/v correlated positively with increasing BOO grade. Conclusions: WIV can be calculated from simple urodynamic parameters using the bladder power integration method. WIV/v may be a marker of BOO grade, and the bladder contractile function can be evaluated by WIV and WIV/t.

    Diseases and conditions affecting the lower urinary tract are a leading cause of dysfunctional sexual health, incontinence, infection, and kidney failure. The growth, differentiation, and repair of the bladder's epithelial lining are regulated, in part, by fibroblast growth factor (FGF)-7 and -10 via a paracrine cascade originating in the mesenchyme (lamina propria) and targeting the receptor for FGF-7 and -10 within the transitional epithelium (urothelium). The FGF-7 gene is located at the 15q15-q21.1 locus on chromosome 15 and four exons generate a 3.852-kb mRNA. Five duplicated FGF-7 gene sequences that localized to chromosome 9 were predicted not to generate functional protein products, thus validating the use of FGF-7-null mice as an experimental model. Recombinant FGF-7 and -10 induced proliferation of human urothelial cells in vitro and transitional epithelium of wild-type and FGF-7-null mice in vivo.To determine the extent that induction of urothelial cell proliferation during the bladder response to injury is dependent on FGF-7, an animal model of partial bladder outlet obstruction was developed. Unbiased stereology was used to measure the percentage of proliferating urothelial cells between obstructed groups of wild-type and FGF-7-null mice. The stereological analysis indicated that a statistical significant difference did not exist between the two groups, suggesting that FGF-7 is not essential for urothelial cell proliferation in response to partial outlet obstruction. In contrast, a significant increase in FGF-10 expression was observed in the obstructed FGF-7-null group, indicating that the compensatory pathway that functions in this model results in urothelial repair.

    Full Text Available Objectives: Many morphological changes occur in the bladder due to bladder outlet obstruction (BOO in pa-tients with benign prostate hyperplasia (BPH. In the present study we evaluated the relationship between in-terureteric distance (IUD of the orifices and BOO in BPH patients.Materials and methods: Thirty-seven consecutive pa-tients with lower urinary tract symptoms at the urology polyclinic included in the study. Patients divided into 2 groups according to maximal flow rate (Qmax. The first group constituted of 18 patients with Qmax 15ml/s. The IUD measurement was performed with Doppler ultrasonography.Results: There was no significant difference between the groups regarding mean age and prostate volume. Mean IUD in the first group was 32.7±5.4 mm and mean IUD in the second group was 31.5±5.1 mm. There was no statistically significant difference between the groups regarding the IUD.Conclusions: Data obtained from the study revealed that measurement of IUD with Doppler ultrasonography not significantly related to BOO.

    Objective To evaluate whether a new herbal formula (WSY-1075) could prevent partial bladder outlet obstruction induced overactive bladder and to investigate its anti-oxidant and anti-inflammatory effects. Methods Twenty four male Sprague-Dawley rats were used in the study. The experimental group was partially obstructed via perineal ligation. After 2 weeks, the rats were randomly divided into one of three treatment groups: control (n=8), oxybutynin (3 mg/kg) (n=8), and WSY-1075 (400 mg/kg) (n=8). After 4 weeks of treatment, ligations were removed and cystometrograms were performed twice a week apart. The pro-inflammatory cytokine levels, anti-oxidant effects and histological findings were also noted. Results The use of oxybutynin and WSY-1075 showed significantly increased bladder compliance and diminished non-voiding contractions. Treatment with Oxybutynin and WSY-1075 significantly decreased pro-inflammatory cytokine levels. The levels of superoxide dismutase increased in the WSY-1075 group, which confirmed the anti-oxidant effect of WSY-1075. Conclusions WSY-1075 may be effective in treating detrusor overactivity do not respond to resolution of bladder outlet obstruction.

    The objective of the study was to evaluate possible changes of the gene expression and localization of the enzymes, heme oxygenase and nitric oxide synthase (NOS), with reference to increase of collagen type III in response to the partial obstruction of the bladder. Following initial obstruction, whole rat bladders were removed for real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. Real-time RT-PCR demonstrated significantly enhanced expression of HO (p < 0.01) and collagen type III (p < 0.001) gene on postoperative day 14. Enhanced expression of NOS gene was seen only on postoperative day 4 (p < 0.01). Immunohistochemistry revealed that immunoreactivity to HO-1 had much in common in neural cells and fibers, although immunoreactivity to HO-2 and iNOS was relatively weak. This study suggested gene expression of HO, especially HO-1, was more dramatically changed than NOS, and was upregulated simultaneously with increase of collagen type III after obstruction. HO systems could be involved in the pathogenesis of bladder dysfunction related to increase of collagen type III after obstruction. PMID:17406140

    Objective To study the relationship between the degree of bladder outlet obstruction (BOO), detrusor contractility and residual urine in patients suffering from benign prostatic hyperplasia (BPH).Methods In 181 patients with BPH, degree of BOO, detrusor contractility, residual urine caculated from cathetering combined with the difference between the filling and the voiding were recorded and analysized statistically using urodynamic technique.Results Residual urine increased when the detusor contractility was weakened (F=12.134, P=0.001). In patients wih severe BOO, there was no significant difference in residual urine (F=2.386, P=0.071).Conclusions Increased residual urine is mainly resulted from decreased detrusor contractility. BOO has no significant influence on residual urine. Some patients with normal or weakened detrusor contractility may have more residual urine

    Background To investigate the role of TRPV1 in the pathological process of DO induced by partial bladder outlet obstruction (pBOO). Methods In 40 female Wistar rats, pBOO was achieved by partial urethral ligation and urodynamic analysis was taken to filter the DO rats six weeks later. Urinary bladder and dorsal root ganglia (DRG) were removed and RT-PCR, Western Blot and IHC were performed to investigate the expression and location of TRPV1 in control and DO rats. Effect of different concentrations of TRPV1 agonist, as well as TRPV1 antagonist, was also evaluated with isolated detrusor strips. Results Forty female Wistar rats received pBOO surgery and 24 of them developed DO. Expression of TRPV1 mRNA and protein in urinary bladder and dorsal root ganglia (DRG) significantly increased in pBOO induced OAB rats. While that did not significantly change after de-urothelial treatment both in OAB and control rats. Immunohistochemistry observed linear TRPV1-reactive staining mainly in suburothlial and muscular layer. In isolated detrusor strips studies, the amplitude and frequency of contractions of DO tissues were significantly higher than that of control ones (PCapsaicin significantly increased the amplitude but not frequency of detrusor intrinsic contractility and this effect was enhanced in OAB conditions. All changes induced by capsaicin were blocked by capsazepine pre-incubated. Conclusions In pBOO induced DO rats, over-expressed TRPV1 was involved in DO pathological process by directly sensitizing bladder afferent fibers or indirectly enhancing detrusor intrinsic properties.

    The purpose of this study was to determine the activity of the autonomic nervous system (ANS), using spectral analysis of the heart rate variability (HRV) in the model of partial bladder outlet obstruction (PBOO) in rats treated with selected non-steroidal anti-inflammatory drugs (NSAID): piroxicam (PRX) or meloxicam (MLX), and following administration of PGF2a prostaglandin analogue (Enzaprost F5). Neither the use of PGF2a analogue nor of MLX, caused significant changes in the HRV spectrum (except for HRV spectrum total power reduction with MLX). The use of PRX caused reduction of the total power and powers of all components of the HRV spectrum (except for VLF). Moreover, increased nLF and reduced nHF were observed. The obtained results suggest that the total prostaglandin synthesis block with a non-selective cyclooxygenase inhibitor (PRX) results in reduced ANS total activity, with decreased parasympathetic activity and a relative sympathetic predominance. The preferential cyclooxygenase-2 block (MLX) caused reduction of the total ANS activity as well, however with no clear disproportion of any part of the ANS. Therefore, prostaglandin synthesis inhibition and associated decrease of parasympathetic activity may constitute an additional and favourable feature of NSAID pharmacodynamics in the treatment of BPH.

  1. Sodium Tanshinone IIA Sulfonate Ameliorates Bladder Fibrosis in a Rat Model of Partial Bladder Outlet Obstruction by Inhibiting the TGF-β/Smad Pathway Activation.

    Directory of Open Access Journals (Sweden)

    Xiaoxiao Jiang

    Full Text Available Transforming growth factor (TGF-β1 is known to play a pivotal role in a diverse range of biological systems including modulation of fibrosis in several organs. The precise role of TGF-β/Smad signaling in the progression of bladder fibrosis secondary to partial bladder outlet obstruction (PBOO is yet to be conclusively. Using a rat PBOO model, we investigated TGF-β1 expression and exaimined whether sodium tanshinone IIA sulfonate (STS could inhibit TGF-β/Smad signaling pathway activation and ameliorate bladder fibrosis. Forty-eight female Sprague-Dawley rats were randomly divided into three groups: sham operation group (n = 16, PBOO operation without STS treatment group (n = 16 and PBOO operation with STS treatment group (n = 16. Thirty-two rats underwent the operative procedure to create PBOO and subsequently received intraperitoneal injections of STS (10 mg/kg/d; n = 16 or vehicle (n = 16 two days after the surgery. Sham surgery was conducted on 16 rats, which received intraperitoneal vehicle injection two days later. In each of the three groups, an equal number of rats were sacrificed at weeks 4 and 8 after the PBOO or sham operation. The TGF-β/Smad signaling pathway was analyzed using western blotting, immunohistochemical staining and reverse transcriptase polymerase chain reaction (RT-PCR. One-way analysis of variance was conducted to draw statistical inferences. At 4 and 8 weeks, the expression of TGF-β1 and phosphorylated Smad2 and Smad3 in STS-treated PBOO rats was significantly lower than in the PBOO rats not treated with STS. Alpha smooth muscle actin (α-SMA, collagen I and collagen III expression at 4 and 8 weeks post PBOO was lower in STS-treated PBOO rats when compared to that in PBOO rats not treated with STS. Our findings indicate that STS ameliorates bladder fibrosis by inhibiting TGF-β/Smad signaling pathway activation, and may prove to be a potential therapeutic measure for preventing bladder fibrosis secondary to PBOO

  3. Bladder neck obstruction in women

    International Nuclear Information System (INIS)

    Primary bladder nech obstruction in women is quite rare and its symptoms - dysuria, frequency and urgency - are equivocal. Routine radiological investigations alone do not allow a diagnosis to be made, due to the lack of simultaneous measurements of detrusorial pressure and uroflow. A precise diagnosis is thus to be obtained by synchronous video-urodynamic studies which allow the depiction of nonfunneling or tight bladder neck during the entire phase of detrusor contraction, of bladder trabeculations and diverticula, vesico-ureteral reflux, long micturition time and incomplete voiding. When these radiological signs are associated with a rise in detrusorial voiding pressure over 60 cm of water and with peak urine flow lower than 15 ml/s, the diagnosis of bladder neck obstruction is unquestionable and the appropriate farmacologic/endoscopic treatment can be administered

    Objective To compare two methods for establishing an animal model of overactivity bladder caused by bladder outlet obstruction in beagle dogs. Methods Twenty-six healthy female beagles were randomly divided into three groups, which were group A ( n =10 ) , group B ( n =10 ) , and control group ( n =6 ) . The group A was given a retropubic approach midprostatic obstruction. The group B was given an urethral partial ligation through transurethral way. The control group underwent just exposure of the bladder neck without midprostatic obstruction through retropubic approach. Urodynamic study was carried out in these groups after 12 weeks. Results The operation time of the group B (10. 7 ± 3. 9 min) was shorter than the control group (15. 2 ± 2. 1) min, which was further shorter than the group A (18.4 ±3.2 min) (F=67.97, P=0.02). Urinary dynamics test showed no significant difference among the 3 groups before the operation of (P>0. 05). At 12 weeks after the operation, 8 dogs from the group A and 10 dogs from group B were found with detrusor contraction wave in urine storage period, while the control group did not appear. The detrusor pressure, maximum bladder capacity, residual urine in the group A and group B were significantly higher than the control group and before operation (P0. 05), and there was no significant difference in the control group between preoperation and postoperation (P>0. 05). Conclusions Both retropubic and transurethral approaches can be used to successfully establish bladder outlet obsteuction in female beagles. As compared to retropubic approach, the transurethral approach has advantages such as shorter operation time, better reproducibility and stability of the animal models, which is suitable for studying transurethral intracavitary treated by minimally invasive surgery.%目的:比较两种犬膀胱出口梗阻( bladder outlet obstruction,BOO)诱导膀胱过度活动症( overactivity bladder, OAB)模型制备方法的效果。方法将26

    Full Text Available BACKGROUND: Chromophobe (Chr RCC is a distinctive entity of Renal Cell Carcinoma (RCC arising from cortical portion of collecting duct of kidneys with an incidence of 3 - 5% (1. Localized Cromophobe RCC suggests a better prognosis than other type of RCC but there is a poorer outcome with sarcomatoid features or metastatic disease (1 . Renal cell carcinoma is one of the few tumors known to metastasize to the pancreas (2 . Metastatic pancreatic cancer is rare, accounting for approximately 2% of all pancreatic malignancies, and most cases arise from renal cell carcinoma (3. Of patients with pancreatic metastases, 12% present with synchronous extra pancreatic metastasis, and they have a poor prognosis . Chromophobe RCC presenting as obstructive jaundice and gastric outlet obstruction has been cited infrequently in literature (3 . The purpose of this paper is two: first, a rare case ChRCC with atypical presentation with obstructive jaundice, gastric outlet obstruction and pancreatic metastasis. Second, multidisciplinary treatment involving General surgeon, Medical Gastroenterologist, Surgical Gastroenterologist, Urologist, Interventional Radiologist and a Medical oncologist.

    Hemangioma, a most frequently encountered primary benign tumor of the liver, is generally determined incidentally during the course of radiologic tests for other reasons. Most lesions are less than 3 cm and a significant proportion of patients are asymptomatic, although the size and location of the lesion in some patients may be associated with the onset of symptoms. Pressure on the stomach and duodenum of giant hemagiomas developing in the left lobe of the liver, in particular, may result in the development of abdominal pain, nausea, vomiting, and feeling bloated, which are characteristic of a gastric outlet obstruction. A 42-year-old man presented with findings of gastric outlet obstruction and weight loss as a result of a giant hepatic hemangioma. PMID:23438272

    Full Text Available Heterotopic (ectopic pancreas is relatively rare and is defined as abnormally situated pancreatic tissue has no contact with the normal pancreas and has its own ductal system and blood supply. It is usually an incidental finding in clinical practice. It most often occurs in the proximal gastrointestinal tract – gastric heterotopic pancreas. It may become clinically evident when complicated by pathological changes such as pancreatitis, cystic dystrophy with obstruction as especially gastric outlet obstruction. In this report a 29 – year old man with nausea, recurrent vomiting an abdominal pain is described. Gastroduodenal endoscopic examination, upper GI barium X-ray, ultrasonography revealed a submucosal tumor at the prepyloric area on the posterior wall of the stomach with gastric outlet obstruction. A degenerated gastrointestinal stromal tumor was suspected. Limitated distal antrectomy was performed and a histological diagnosis of gastric heterotopic pancreas was confirmed. The patient had an uneventful postoperative course and was discharged 5 days after operation and remains healthy and symptom-free in the follow-up of 6 months. This is a report of a case of gastric outlet obstruction resulting for pancreatic heterotopia in the gastric antrum with cystic dystrophy after acute pancreatitis in an adult man. The incidence of symptomatic heterotopic pancreas is low and preoperative diagnosis is difficult. Although endoscopy ultrasound is helpful for diagnosis, it is difficult to distinguish from stromal tumor. Frozen section should be taken so as to distinguish heterotopic pancreas from malignant tumors. Surgical excision by minimally invasive approach provides symptomatic relief and is recommended.

    Full Text Available Abstract Background Hyperplastic polyps are the most common polypoid lesions of the stomach. Rarely, they cause gastric outlet obstruction by prolapsing through the pyloric channel, when they arise in the prepyloric antrum. Case presentation A 62-year-old woman presented with intermittent nausea and vomiting of 4 months duration. Upper gastrointestinal endoscopy revealed a 30 mm prepyloric sessile polyp causing intermittent gastric outlet obstruction. Following submucosal injection of diluted adrenaline solution, the polyp was removed with a snare. Multiple biopsies were taken from the greater curvature of the antrum and the corpus. Rapid urease test for Helicobacter pylori yielded a negative result. Histopathologic examination showed a hyperplastic polyp without any evidence of malignancy. Biopsies of the antrum and the corpus revealed gastritis with neither atrophic changes nor Helicobacter pylori infection. Follow-up endoscopy after a 12-week course of proton pomp inhibitor therapy showed a complete healing without any remnant tissue at the polypectomy site. The patient has been symptom-free during 8 months of follow-up. Conclusions Symptomatic gastric polyps should be removed preferentially when they are detected at the initial diagnostic endoscopy. Polypectomy not only provides tissue to determine the exact histopathologic type of the polyp, but also achieves radical treatment.

    Gastric outlet obstruction (GOO) presenting beyond the newborn period is a relatively rare condition, when infantile hypertrophic pyloric stenosis (IHPS) is excluded. This report describes the clinical features, evaluation and management of 18 patients with GOO which was not caused by IHPS. The sex, age, and main presenting features were recorded on admission. Hemoglobin estimation, serum chemistry and blood gas analysis were also assessed in these patients. The diagnosis was confirmed with gastrointestinal barium, B ultrasound, gastroscopy, or at surgery. Some of them underwent gastroscopy with biopsy sampling for rapid urease test or histologic examination with Giemsa stains for Helicobacter pylori. Thirteen patients had peptic ulcer disease, of which six were successfully treated with medications. While the other seven needed operative management which included Heineke-Mikulicz pyloroplasty, gastroduodenostomy or gastrojejunostomy, respectively. All the patients who had Heineke-Mikulicz pyloroplasty or gastrojejunostomy developed bile reflux gastritis that could be alleviated with omeprazol. None of the patients developed dumping syndrome, failing to thrive, or anemia. Three children with antral diaphragm recovered without any complications by diaphragm excision with Heineke-Mikulicz pyloroplasty. The pylorus was compressed by fibrotic band in one 30-month boy, and he recovered uneventfully with Heineke-Mikulicz pyloroplasty during 10-year follow-up. Gastric outlet obstruction secondary to ingestion of sulfuric acid was noted in one patient, and he was successfully treated with gastroduodenostomy. Our data suggests that the satisfactory results could be expected in children with GOO with different therapeutic modalities based on the specific cause and degree of obstruction. PMID:16041609

    Full Text Available Introduction and aim: The video-urodynamics study is the principal exam to establish a possible primary bladder neck obstruction (PBNO condition. While trans-rectal ultrasonography plays an important role in the evaluation of the low urinary tract symptoms (LUTS and the severity of bladder outlet obstruction (BOO in men, the use of the transvaginal ultrasound (TVUS in women with symptoms suggesting BOO remains unclear. We tried to check the utility of the TVUS in women with PBNO condition. Material and methods: We selected female patients which presented BOO without pelvic organ prolapse (POP. According to the data of the video-urodynamic exam we selected the patients with the suspicion of PBNO. A TVUS in basal and during micturition was performed before and after surgery. Results: TVUS showed a closed bladder neck bladder in basal condition and during micturition similarly to the fluoroscopic image during video-urodynamics. The mean distance from bladder neck to the vaginal mucosa resulted 1.3 cm in this patients. Conclusions: TVUS results worthy in the evaluation of patients with PBNO before and after surgery.

    The placement of a 1.5 cm. wide silicone sheath around a newly constructed urethra/bladder neck to ensure maintenance of repair length and to facilitate future placement of a sphincter cuff was reported by our institution in 1985. We present our long-term followup and new recommendations for use of the silicone sheath. A total of 15 silicone sheaths was placed between March 1981 and July 1984. Of the sheaths 14 were placed at the time of urinary reconstruction around the Young-Dees-Leadbetter bladder neck repair and 1 was placed after erosion of an artificial urinary sphincter cuff. Of the 15 sheaths 10 have eroded into the urethra and 4 sheaths remain in situ. Another sheath was replaced 2 years after its original insertion with an artificial urinary sphincter cuff. Mean time to erosion was 48.2 months, with a range of 2 to 108 months. Long-term followup of 10 patients revealed that 4 ultimately required ligation of the bladder neck and construction of continent stoma after erosion, 1 is dry after placement of a bulbar artificial urinary sphincter, 2 remain dry after removal of the eroded sheath alone, 2 required bladder neck revision to achieve continence after erosion and the most recent patient remains diverted with a suprapubic tube. All 4 patients with sheaths still remaining are dry without evidence of erosion (mean duration 116 months). These long-term results using a silicone wrap around a newly constructed bladder neck reveal an unacceptably high rate of erosion. Therefore, we no longer recommend or support the use of the silicone sheath in the manner we have described for bladder neck reconstruction. PMID:8326628

    Full Text Available Abstract Background Secondary urethral stone although rare, commonly arises from the kidneys, bladder or are seen in patients with urethral stricture. These stones are either found in the posterior or anterior urethra and do result in acute urinary retention. We report urethral obstruction from dislodged bladder diverticulum stones. This to our knowledge is the first report from Nigeria and in English literature. Case presentation A 69 year old, male, Nigerian with clinical and radiological features of acute urinary retention, benign prostate enlargement and bladder diverticulum. He had a transurethral resection of the prostate (TURP and was lost to follow up. He re-presented with retained urethral catheter of 4months duration. The catheter was removed but attempt at re-passing the catheter failed and a suprapubic cystostomy was performed. Clinical examination and plain radiograph of the penis confirmed anterior and posterior urethral stones. He had meatotomy and antegrade manual stone extraction with no urethra injury. Conclusions Urethral obstruction can result from inadequate treatment of patient with benign prostate enlargement and bladder diverticulum stones. Surgeons in resource limited environment should be conversant with transurethral resection of the prostate and cystolithotripsy or open prostatectomy and diverticulectomy.

    This study was designed to investigate whether reduced adenosine formation linked to deficits in extracellular ATP hydrolysis by NTPDases contributes to detrusor neuromodulatory changes associated with bladder outlet obstruction in men with benign prostatic hyperplasia (BPH). The kinetics of ATP catabolism and adenosine formation as well as the role of P1 receptor agonists on muscle tension and nerve-evoked [(3)H]ACh release were evaluated in mucosal-denuded detrusor strips from BPH patients (n = 31) and control organ donors (n = 23). The neurogenic release of ATP and [(3)H]ACh was higher (P bladders. Relaxation of detrusor contractions induced by acetylcholine required 30-fold higher concentrations of adenosine. Despite VAChT-positive cholinergic nerves exhibiting higher A(1) immunoreactivity in BPH bladders, the endogenous adenosine tonus revealed by adenosine deaminase is missing. Restoration of A1 inhibition was achieved by favoring (1) ATP hydrolysis with apyrase (2 U mL(-1)) or (2) extracellular adenosine accumulation with dipyridamole or EHNA, as these drugs inhibit adenosine uptake and deamination, respectively. In conclusion, reduced ATP hydrolysis leads to deficient adenosine formation and A(1) receptor-mediated inhibition of cholinergic nerve activity in the obstructed human bladder. Thus, we propose that pharmacological manipulation of endogenous adenosine levels and/or A(1) receptor activation might be useful to control bladder overactivity in BPH patients. PMID:26521170

    Full Text Available Bouveret's syndrome is a rare condition of gastric outlet obstruction resulting from the migration of a gallstone through a choledochoduodenal fistula. Due to the large size of these stones and the difficult location in which they become impacted, endoscopic treatment is unsuccessful and most patients require surgery. We report the case of an elderly male who presented with nausea and hematemesis, and was found on CT scan and endoscopy to have an obstructing gallstone in his duodenal bulb. After several endoscopic sessions and the use of multiple instruments including a Holmium: YAG laser and electrohydraulic lithotripter, fragmentation and endoscopic removal of the stone were successful. We believe this to be the first case of Bouveret's syndrome successfully treated by endoscopy alone in the United States. We describe the difficulties encountered which necessitated varied and innovative therapeutic techniques.

    Background. Self-expandable metal stents (SEMs) are increasingly being utilised instead of invasive surgery for the palliation of patients with malignant gastroduodenal outlet obstruction. Aim. To review two tertiary centres' experience with placement of SEMs and clinical outcomes. Methods. Retrospective analysis of prospectively collected data over 12 years. Results. Ninety-four patients (mean age, 68; range 28-93 years) underwent enteral stenting during this period. The primary tumour was gastric adenocarcinoma in 27 (29%) patients, pancreatic adenocarcinoma in 45 (48%), primary duodenal adenocarcinoma in 8 (9%), and cholangiocarcinoma and other metastatic cancers in 14 (16%). A stent was successfully deployed in 95% of cases. There was an improvement in gastric outlet obstruction score (GOOS) in 84 (90%) of patients with the ability to tolerate an enteral diet. Median survival was 4.25 months (range 0-49) without any significant differences between types of primary malignancy. Mean hospital stay was 3 days (range 1-20). Reintervention rate for stent related complications was 5%. Conclusion. The successful deployment of enteral stents achieves excellent palliation often resulting in the prompt reintroduction of enteral diet and early hospital discharge with minimal complications and reintervention.

    Full Text Available Abstract Introduction Gastric outlet obstruction is a clinical syndrome caused by a variety of mechanical obstructions. Peptic ulcer disease used to be responsible for most gastric outlet obstruction, but in the last 40 years the prevalence of malignant tumors has risen significantly. Adhesive disease is an infrequent and insidious cause of mechanical gastric outlet obstruction. Case presentation We report the case of a 78-year-old Caucasian man who had a clinical history of a right nephrectomy for malignancy three years earlier and who was admitted for a severe gastric outlet obstruction (score of 1 confirmed both by an upper endoscopy and by a fluoroscopic view after contrast injection. A computed tomography scan and a laparotomy, with omental biopsies, showed a peritoneal carcinomatosis with the development of abdominal adhesions that prompted an abnormal gastric rotation around the perpendicular axis of his antrum with a dislocation in the empty space of his right kidney. Symptoms disappeared after surgical bypass through a gastrojejunostomy. Conclusions Our patient experienced a very rare complication characterized by the development of adhesions due to peritoneal carcinomatosis caused by a renal carcinoma treated with nephrectomy. These adhesions prompted an abnormal dislocation of his antrum, as an internal hernia, in the empty space of his right kidney.

    Full Text Available Background: In the modern era, the major cause of gastric outlet obstruction (GOO is known to be a malignancy, especially in the developed world. Many books and articles do suggest that the benign causes continue to be the major cause of GOO in the developing world however, there is growing evidence proving the contrary. Males were (more commonly affected females and individuals in their fifth and sixth decade have been the predominant age group in the majority of studies. There is a minimal data of GOO from South India. Aims: A retrospective analysis of the endoscopic findings of patients presenting with features of GOO to determine the demographic and etiological patterns. Materials and Methods: A retrospective study of the endoscopic findings of patients with GOO from January 2005 to January 2014 was done. The diagnosis of GOO was based on clinical presentation, and an inability during the upper endoscopy to enter the second portion of the duodenum as documented in the endoscopy registers. Patients who have already been diagnosed with malignancy prior to the endoscopy were excluded from the study; so were the patients with gastroparesis. Results: A total of 342 patients with GOO underwent the endoscopy during the study period. The causes for benign obstruction were predominantly peptic ulcer disease. The major cause for malignant obstruction was carcinoma of stomach involving the distal stomach. The male to female ratio was 3.2:1. The patients with malignancy were older than patients with benign disorders. Most of the patients were in the sixth and seventh decade. The risk of malignancy was higher with increasing age, especially in women. A fourth of all carcinoma stomach presented with GOO. Conclusion: The study demonstrates that the cause for GOO in Kerala, South India is predominantly malignancy. The etiological and demographic patterns were similar to the studies conducted in the developed nations.

    AIM: To ascertain clinical outcome and complications of self-expandable metal stents for endoscopic palliation of patients with malignant obstruction of the gastrointestinal (GI) tract.METHODS: A retrospective review was performed throughout August 2000 to June 2005 of 53 patients with gastric outlet obstruction caused by stomach cancer. All patients had symptomatic obstruction including nausea, vomiting, and decreased oral intake. All received self-expandable metallic stents.RESULTS: Stent implantation was successful in all 53 (100%) patients. Relief of obstructive symptoms was achieved in 43 (81.1%) patients. No immediate stent-related complications were noted. Seventeen patients had recurrent obstruction (tumor ingrowth in 14 patients, tumor overgrowth in 1 patient, and partial distal stent migration in 2 patients). The mean survival was 145 d. Median stent patency time was 187 d.CONCLUSION: Endoscopic placement of self-expandable metallic stents is a safe and effective treatment for the palliation of patients with inoperable malignant gastric outlet obstruction caused by stomach cancer.

  16. An Assessment of Radiologically Inserted Transoral and Transgastric Gastroduodenal Stents to Treat Malignant Gastric Outlet Obstruction

    International Nuclear Information System (INIS)

    IntroductionSelf-expanding metallic stents (SEMS) are used to palliate malignant gastric outlet obstruction (GOO) and are useful in patients with limited life expectancy or severe medical comorbidity, which would preclude surgery. Stenting can be performed transorally or by a percutaneous transgastric technique. Our goal was to review the outcome of patients who underwent radiological SEMS insertion performed by a single consultant interventional radiologist. Methods: Patients were identified from a prospectively collected database held by one consultant radiologist. Data were retrieved from radiological reports, multidisciplinary team meetings, and the patients’ case notes. Univariate survival analysis was performed. Results: Between December 2000 and January 2011, 100 patients (63 males, 37 females) had 110 gastroduodenal stenting procedures. Median age was 73 (range 39–89) years. SEMS were inserted transorally (n = 66) or transgastrically (n = 44). Site of obstruction was the stomach (n = 37), duodenum (n = 50), gastric pull-up (n = 10), or gastroenterostomy (n = 13). Seven patients required biliary stents. Technical success was 86.4 %: 83.3 % for transoral insertion, 90.9 % for transgastric insertion. Eleven patients developed complications. Median GOO severity score: 1 pre-stenting, 2 post-stenting (p = 0.0001). Median survival was 54 (range 1–624) days. Post-stenting GOO severity score was predictive of survival (p = 0.0001). Conclusions: The technical success rate for insertion of palliative SEMS is high. Insertional technique can be tailored to the individual depending on the location of the tumor and whether it is possible to access the stomach percutaneously. Patients who have successful stenting and return to eating a soft/normal diet have a statistically significant increase in survival

    Gastric outlet obstruction in adults is usually caused by pyloric stenosis secondary to peptic ulcer disease or malignancy. However, there are few other causes such as a foreign body and external compression due to pseudocyst pancreas. We present a rare aetiology of a large collection of pus in the lesser sac in our patient causing gastric outlet obstruction. A perforated peptic ulcer was suspected in our patient who had symptoms of sudden onset pain in epigastric region which was referred to back. This was followed by pain in upper abdomen, vomiting, constipation and fever for which patient was being managed conservatively before being referred to us. The CECT didn't show any leakage of contrast to the lesser sac making the possibility of healed perforation likely as all other causes were ruled out at the time of presentation to our hospital. The CECT scan ruled out other causes of gastric outlet obstruction with normal wall thickness of the stomach and duodenum along with normal looking liver, pancreas and no lymphadenopathy. The liver function tests and serum amylase were within normal limits. Along with this, there was another unrelated rare coincidental finding of aortoiliac occlusive disease termed as Leriche's syndrome. Ultrasound guided percutaneous drainage was done following which the patient's obstruction was relieved and patient was referred to the department of vascular surgery for the mangement of aortoiliac occlusive disease.

    Malignant gastric outlet obstruction (GOO) is a commoncondition that results from locally advanced malignanciesin the upper gastrointestinal tract, such aspancreatic, gastric, and other carcinomas. Two typesof procedures for malignant GOO, namely, gastrojejunostomy(GJ) with laparotomy or a laparoscopicapproach and endoscopic stenting (ES), are currentlyavailable. Although numerous previous reports haveclarified the benefits and drawbacks of each procedure,whether GJ or ES should be used in patients with GOOthat results from gastric cancer who may have a longerlife expectancy than patients with other malignancieshas not been determined. In this review, which focuseson gastric cancer-induced GOO, we analyzed the twosystematic reviews and a meta-analysis that comparedGJ and ES and outlined the current status of GOOtreatment. We also provide an updated review thatincludes laparoscopic GJ. Various data from 13 studiesin one review and 6 studies in another review wereanalyzed. Although the main results of the presentreview indicated that both GJ and ES were efficacioustreatments in patients with GOO that resulted fromgastric cancer, current evidence suggests that GJ maybe the preferable procedure given its good performancestatus and improved prognosis in gastric cancer patients.

    We report late-onset hypertrophic pyloric stenosis in a 17-year-old female. She presented with abdominal pain and an episode of upper gastrointestinal hemorrhage and subsequently developed gastric outlet obstruction. Work-up revealed circumferential pyloric thickening, delayed gastric emptying, and a stenotic, elongated pyloric channel. Biopsies showed benign gastropathy, negative for Helicobacter pylori, without eosinophilic infiltrates. Botulinum toxin injection provided limited relief. Diagnostic laparoscopy confirmed the hypertrophic pylorus and we performed laparoscopic pyloromyotomy. The patient tolerated the procedure well and had complete symptom resolution at 1-year follow-up. Hypertrophic pyloric stenosis is a rare cause of gastric outlet obstruction in adolescents and may be managed successfully with laparoscopic pyloromyotomy. PMID:27506212

    Full Text Available INTRODUCTION: Gastric outlet obstruction (GOO mechanically impedes gastric emptying, normal emptying of the stomach. It is a diagnostic and therapeutic challenge for general surgeons in their daily practice. There is a paucity of publications regarding GOO in our setting. This paper highlights the etiology, clinical presentation and treatment outcome of GOO. METHODS: A Prospective study was conducted enrolling patients with GOO treated at Victoria hospital, Bangalore medical college during September 2008 to august 2010. Data was tabulated and analyzed using descriptive statistical methodology. RESULTS: carcinoma stomach with antral growth and cicatrized duodenal ulcer (both 41.5% were the most common cause of gastric outlet obstruction. Male were more affected than females (2.5:1. Most common symptom was vomiting and abdominal pain (noted among all, followed by loss of appetite (83% and loss of weight (82.35%. 94.1% patients of Cicatrized duodenal ulcer underwent truncal vagotomy with posterior gastrojejunostomy and 5.9% underwent truncal vagotomy with antrectomy. 58.8% patients of carcinoma stomach, underwent distal gastrectomy with ante-colic Roux-en-Y gastro- jejunostomy, 12.1% patients underwent subtotal gastrectomy with ante-colic and Roux-en-Y gastro jejunostomy and 4.8% patients underwent palliative gastrojejunostomy. In corrosive antral stricture Billroth I gastrectomy was done. Patients of pancreatic malignancy underwent palliative anterior gastrojejunostomy and pseudo- pancreatic cyst was treated by cystojejunostomy. The average hospital stay was 12-15 days and an overall mortality of 5.8% for malignant patients was noted. CONCLUSION: Study concludes that gastric outlet obstruction is an important and a common surgical condition in tertiary hospital. Malignancy and benign cicatrized duodenal ulcer being the most common cause. Early surgical intervention is of paramount importance to avoid the morbidity and mortality associated with GOO.

    This article reports a rare case of acute pyelonephritis secondary to left ureteral obstruction by a bladder catheter. The patient was 93years old man hospitalized in the hospital emergency department with a 39°C fever and pyuria from an indwelling catheter. Blood test found hyperleukocytosis, inflammatory syndrome and acute renal failure. Diagnosis was confirmed by non-contrast abdominal CT scan showing distal part of the catheter inside left ureteral orifice with ureterohydronephrosis. Treatment consisted in replacing the catheter by a three-way catheter for irrigation and parenteral antibiotics therapy. Clinico-biological evolution was successful and a urinary tract CT scan could be realized at day 9. The left upper urinary tract function was recovered. With a short review of the literature we propose to describe the different procedures to manage those obstructions. PMID:25288585

    Full Text Available Abstract Introduction Bouveret's syndrome is a clinically distinct form of gallstone ileus caused by the formation of a fistula between the biliary tract and duodenum. This case reinforces the need for early recognition and treatment of Bouveret's syndrome, as it is associated with high morbidity and mortality rates. Case presentation An 82-year-old Caucasian woman presented with signs and symptoms of small bowel obstruction. Her laboratory workup showed elevated alkaline phosphatase and amylase levels. Computed tomography of her abdomen revealed pneumobilia, a choledochoduodenal fistula and a gallstone obstructing her distal duodenum. The impacted gallstone could not be extracted endoscopically, so our patient underwent open enterolithotomy successfully. However, the postoperative course was complicated by myocardial infarction, respiratory failure and disseminated intravascular coagulation. She died 22 days after surgery, secondary to cardiopulmonary arrest. Conclusion This case clearly highlights the considerable morbidity and mortality associated with Bouveret's syndrome.

Results: The diagnoses were: rectocele: 2 (5.0%; anismus: 8 (20.0%; perineal descent: 13 (32.5%; sigmoidocele: 6 (15.0%; internal invagination: 10 (25.0%; rectocele + sigmoidocele 9 (22.5%; rectocele + internal invagination 11 (27.5%; rectocele + anismus: 18 (45.0%. Several patients presented multiple disorders. Conclusion: Constipation by obstructed defecation depends on multiple factors and it is important to have an accurate diagnosis. Proctography is essential, but insufficient as a single procedure. The other tests contribute with the diagnosis, therefore, they should be included in the investigation.O diagnóstico da constipação é difícil pela multiplicidade e complexidade das causas. Dos exames diagnósticos, a proctografia é preferida, fornecendo informações da função e visualização de anormalidades. Objetivo: Medir o valor isolado da proctografia, em pacientes com diagnóstico de defecação obstruída. Método: Avaliamos 40 pacientes com constipação intestinal do Ambulatório de Coloproctologia da Santa Casa de Misericórdia de São Paulo. O exame foi feito introduzindo-se 120 mL de contraste no reto e analisando-se as diferentes fases da evacuação.

    Full Text Available Abstract Introduction Cases of gallstone ileus account for 1% to 4% of all instances of mechanical bowel obstruction. The majority of obstructing gallstones are located in the terminal ileum. Less than 10% of impacted gallstones are located in the duodenum. A gastric outlet obstruction secondary to a gallstone ileus is known as Bouveret syndrome. Gallstones usually enter the bowel through a biliary enteral fistula. Little is known about the formation of such fistulae in the course of gallstone disease. Case presentation We report the case of a 72-year-old Caucasian woman born in Germany with a gastric outlet obstruction due to a gallstone ileus (Bouveret syndrome, with a large gallstone impacted in the third part of the duodenum. Diagnostic investigations of our patient included plain abdominal films, gastroscopy and abdominal computed tomography, which showed a biliary enteric fistula between the gallbladder and the duodenal bulb. Our patient was successfully treated by laparotomy, duodenotomy, extraction of the stone, cholecystectomy, and resection of the fistula in a one-stage surgical approach. Histopathological examination showed chronic and acute cholecystitis, with perforated ulceration of the duodenal wall and acute purulent inflammation of the surrounding fatty tissue. Four months prior to developing a gallstone ileus our patient had been hospitalized for cholecystitis, a large gallstone in the gallbladder, cholangitis and a small obstructing gallstone in the common biliary duct. She had been treated with endoscopic retrograde cholangiopancreatography, endoscopic biliary sphincterotomy, balloon extraction of the common biliary duct gallstone, and intravenous antibiotics. At the time of her first presentation, abdominal ultrasound and endoscopic examination (including esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography had not shown any evidence of a biliary enteral fistula.

    2009-03-01

    Full Text Available Abstract Background Ataxia-Telangiectasia syndrome is characterized by progressive cerebellar dysfunction, conjuctival and cutaneous telangiectasias, severe immune deficiencies, premature aging and predisposition to cancer. Clinical and radiographic evaluation for malignancy in ataxia-telangiectasia patients is usually atypical, leading to delays in diagnosis. Case presentation We report the case of a 20 year old ataxia-telangiectasia patient with gastric adenocarcinoma that presented as complete gastric outlet obstruction. Conclusion A literature search of adenocarcinoma associated with ataxia-telangiectasia revealed 6 cases. All patients presented with non-specific gastrointestinal complaints suggestive of ulcer disease. Although there was no correlation between immunoglobulin levels and development of gastric adenocarcinoma, the presence of chronic gastritis and intestinal metaplasia seem to lead to the development of gastric adenocarcinoma. One should consider adenocarcinoma in any patient with ataxia-telangiectasia who presents with non-specific gastrointestinal complaints, since this can lead to earlier diagnosis.

  16. Near-Infrared Spectroscopy of the Bladder: New Parameters for Evaluating Voiding Dysfunction

    International Nuclear Information System (INIS)

    We describe innovative methodology for monitoring alterations in bladder oxygenation and haemodynamics in humans using near-infrared spectroscopy (NIRS). Concentrations of the chromophores oxygenated (O2Hb) and deoxygenated (HHb) haemoglobin and their sum (total haemoglobin) differ during bladder contraction in health and disease. A wireless device that incorporates three paired light emitting diodes (wavelengths 760 and 850 nanometers) and silicon photodiode detector collects data trans cutaneously (10 Hz) with the emitter/detector over the bladder during spontaneous bladder emptying. Data analysis indicates comparable patterns of change in chromophore concentration in healthy children and adults (positive trend during voiding, predominantly due to elevated O2Hb), but different changes in symptomatic subjects with characteristic chromophore patterns identified for voiding dysfunction due to specific pathophysiology: bladder outlet obstruction (males), overactive bladder (females), and non neurogenic dysfunction (children). Comparison with NIRS muscle data suggests altered bladder haemodynamics and/or oxygenation may underlie voiding dysfunction offering new insight into the causal physiology.

    Full Text Available Abstract Background Gastric outlet obstruction (GOO caused by unresectable gastric cancer is a challenging aspect of patient care. There have been no reports involving patients with obstructing gastric cancer and several incurable factors curatively treated by multimodal treatments. Case presentation We report a case of 55-year-old man who was diagnosed with a poorly differentiated adenocarcinoma in the pre-pyloric antrum with GOO by gastroscopy. An abdominal computed tomography (CT scan revealed thickening of the gastric wall and adjacent fat infiltration, and a large amount of food in the stomach suggesting a passage disturbance, enlarged lymph nodes along the common hepatic and left gastric arteries, and multiple hepatic metastases. The serum carcinoembryonic antigen (CEA level was 343 ng/ml and the carbohydrate antigen (CA 19-9 level was within normal limits. The patient underwent a laparoscopic gastrojejunostomy for palliation of the GOO. On the 3rd and 12th days after surgery, he received intraperitoneal chemotherapy with 40 mg of docetaxel and 150 mg of carboplatin. Simultaneously, combined chemotherapy with 85 mg/m2 of oxaliplatin for the 1st day and 600 mg/m2 of 5-FU for 2 days (FOLFOX regimen was administered from the 8th post-operative day. After completion of nine courses of FOLFOX, the patient achieved a complete response (CR with complete disappearance of the primary tumor and the metastatic foci. He underwent a radical subtotal gastrectomy with D3 lymph node dissection 4 months after the initial palliative surgery. The pathologic results revealed no residual primary tumor and no lymph node metastasis in 43 dissected lymph nodes. He has maintained a CR for 18 months since the last operation. Conclusion Combination chemotherapy with systemic and intraperitoneal chemotherapy following laparoscopic bypass surgery showed marked efficacy in the treatment for unresectable advanced gastric cancer with GOO.

    Introduction To evaluate the impact of continuous positive airway pressure (CPAP) therapy on overactive bladder (OAB) symptoms in women with obstructive sleep apnea syndrome (OSAS). Material and methods One-hundred and fifty women underwent an overnight polysomnography study between May 2014 and September 2014. Their voiding symptoms were evaluated using the OAB symptom score (OABSS) and International Consultation on Incontinence Questionnaire Short-Form at OSAS diagnosis and approximately 3-months after CPAP therapy. OSAS severity was assessed according to the apnea-hypopnea-index. Results We evaluated 140 women and 111 of them (79.3%) reported symptoms consistent with OAB. There were no statistically significant differences between OSAS severity with a prevalence of OAB (p = 0.92). The prevalence of urinary incontinence (UI) was 35.7% (n = 50) and 39.6% (n = 44) in all patients and patients with OAB, respectively. There were no statistically significant differences between UI with OAB (p = 0.58). Baseline OABSS is comparable between OSAS severity (p = 0.143). After 3-months CPAP therapy, OABSS and ICIQ-SF sum scores were significantly decreased in patients with severe and moderate OSAS (p <0.01), however, change of OABSS sum score was insignificant in patients with mild OSAS (p = 0.44). Conclusions CPAP therapy improves the OAB, OABSS and ICIQ-SF scores in women with severe and moderate OSAS. OSAS-induced OAB may be alleviated following CPAP therapy. PMID:27123331

    Full Text Available Background: Ultrasound has been shown to be a sensitive method for evaluating patients with chronic obstruction, bladder outlet obstruction, urinary tract infection, renal failure, renal and bladder neoplasm and renal transplants. It is now recommended as the method of choice for preliminary assessment and follow-up of several of these disorders. The objective of the study was to evaluate the specificity and sensitivity of ultrasonographic features of neoplastic lesions of urinary bladder. Methods: Clinical impression about the suspected abnormality was obtained from the case papers or from referring by clinical colleagues. Data was recorded under headings like clinical history, clinical examinations, investigations like urine analysis, serum creatinine and blood urea, X-ray of chest and Kidney Urinary Bladder, pelvic and abdominal Ultrasonography, and if require CT scan and guided biopsy. Results: out of total 35 cases 29 were Transitional Cell Carcinoma, 4 were Squamous Cell Carcinoma, One leiomyoma and one was secondary from bronchogenic carcinoma. Most of tumours were irregular in shape in both TCC and SCC patients. Most of tumour showed heterogeneous echo-texture in ultrasonography. While all SCC showed heterogeneous with calcification echo-texture. Most of the cases had residual urine volume was less than 100 cc. Conclusions: The primary advantage of ultrasound over the conventional study was found to be its ability to detect focal or diffuse bladder wall abnormalities in patients who presented with commonest complaint of painless hematuria.

    Chronic bladder ischemia is potentially a common cause of lower urinary tract symptoms in the elderly. Epidemiological studies have shown a close association between lower urinary tract symptoms and vascular risk factors for atherosclerosis, and investigations using transrectal color Doppler ultrasonography have shown a negative correlation between decreased lower urinary tract perfusion and International Prostate Symptom Score in elderly patients with lower urinary tract symptoms. Bladder blood flow is also known to decrease in men with bladder outlet obstruction as a result of benign prostatic hyperplasia. Studies in animal models suggest that chronic bladder ischemia and repeated ischemia/reperfusion during a micturition cycle might produce oxidative stress, leading to denervation of the bladder and the expression of tissue-damaging molecules in the bladder wall, which could be responsible for the development of bladder hyperactivity progressing to bladder underactivity. The effects of drugs with different mechanisms of action; for example, α1-adrenoceptor antagonists, phosphodiesterase type 5 inhibitors, free radical scavengers and β3-adrenoceptor agonist, have been studied in animal models of chronic bladder ischemia. The drugs, representing different treatment principles for increasing blood flow and decreasing oxidative stress, showed protective effects not only on urodynamic parameters, but also on negative effects on muscle contractility and on detrimental structural bladder wall changes. Improvement of lower urinary tract perfusion and control of oxidative stress can be considered new therapeutic strategies for treatment of bladder dysfunction induced by chronic ischemia.

    Full Text Available Congenital diverticula in adults are typically associated with bladder outlet obstruction and their manifestation is most commonly by urinary sepsis. The case of a 69 years old male patient who attended consultation because of nocturia, thin urine stream, pushing, urgent urination and sense of incomplete emptying is presented. Through rectal examination grade I prostate with discrete grade I asymmetry consistent with right nodular lobe that did not rise to the surface was detected. During the physical examination tumor mass was palpated in the lower abdomen region. It was painless. Ultrasound and cystography showed giant bladder diverticulum with a narrow neck into the right lateral wall of the bladder. Cystoscopy confirmed the diagnosis and the patient was treated trough surgery. Histology revealed mucosal layers and muscle and adventitia in the wall, thus confirming congenital origin. Recovering after surgery was satisfactor.

    In non-cardiac operative cases with inflammatory digestive organ disease, bacterial translocation (BT) often results from non-enteral nutrition postoperatively. If coronary artery bypass grafting (CABG) is performed in the case having old myocardial infarction (OMI) and inflammatory digestive organ disease at first before non-cardiac operation, he seems vulnerable to have severe complications such as multiple organ failure due to systemic inflammatory response syndrome (SIRS) and preexisting BT postoperatively. We performed a off-pump CABG (OPCAB) for OMI associated with jejunotomy for obstructive ileus due to gall bladder stone. No complication was found in the postoperative course. We conclude that combined operation, non-cardiac surgery after OPCAB is worth considering in those cases. And we think OPCAB is better than conventional CABG in such cases, because cardiopulmonary bypass is known to ponder comparable damages to immune system, coagulation system and others. PMID:16167822

    Full Text Available To explore information hidden in the electromyographic (EMG signals of the urethral sphincter that may be of prognostic significance for patients with primary bladder neck obstruction (PBNO, 41 patients with voiding difficulty were divided into four groups: 1 patients with primary bladder neck obstruction (PBNO with successful (Group 1, n = 14 and 2 unsuccessful (Group 2, n = 8 surgical outcomes, 3 patients with detrusor overactivity (Group 3, n = 7, and 4 patients with detrusor-external sphincter dyssynergia (Group 4, n = 12. All patients underwent baseline urodynamic studies (preoperative for Group 1 and Group 2 for comparison. The results demonstrated that, despite no significant difference in urodynamic parameters between Group 1 and Group 2, the large-scale multiscale entropy (MSE of preoperative EMG (i.e., MSELS(EMG of Group 1 was significantly higher than that of Group 2 without notable difference between Group 1 and Group 3 (i.e., patients with normal sphincter function. Moreover, the MSELS(EMG and small-scale MSE of preoperative EMG (i.e., MSESS(EMG of Group 2 were notably higher than those of Group 4 (i.e., patients with abnormal sphincter function, while both MSELS(EMG and MSESS(EMG of Group 3 were notably higher than those of Group 2. In conclusion, using MSE analysis for assessing preoperative urethral sphincter EMG signals successfully distinguished between PBNO patients with subsequent successful surgery from those with surgical failure possibly due to subtle functional impairment of the urethral sphincter that cannot be detected by routine urodynamic studies. The results, therefore, highlight the potential clinical significance of this analytical tool in guiding urologists regarding their choice of medical versus surgical treatment for this patient population.

    Full Text Available A 63-year old male was referred to our emergency unit due to acute renal failure. The level of serum renal function tests levels, blood urea nitrogen (BUN/creatinine, were 63 mmol/L/848 μmol/L. CT (Computarised Tomography scan showed a huge bladder stone (5 cm x 6 cm x 5 cm with increased bladder wall thickness. Post-renal acute renal failure due to bilateral ureterohydronephrosis was diagnosed. The huge bladder stone was considered to be the cause of ureterohydronephrosis and renal failure. The patient was catheterised and received haemodialysis immediately. He received haemodialysis four times during ten days of hospitalization and the level of serum renal function tests levels (BUN/ creatinine decreased 18 mmol/L/123 μmol/L. After improvement of renal function, we performed cystoscopy that demonstrated normal prostatic urethra and bladder neck and bilaterally normal ureteral orifices. Bladder wall was roughly trabeculated and Bladder outlet was completely obstructed by a huge bladder stone. After cystoscopy open, cystolithotomy was performed to remove calcium phosphate and magnesium ammonium phosphate stone weighing 200 g removed. Four days after operation the patient was discharged uneventfully and urethral catheter was removed on the seventh day. Post-renal acute renal failure due to large bladder stones is rare in literature. According to the our knowledge; early diagnosis of the stone avoid growth to large size and prevent renal failure.

    Full Text Available The kidneys are paired organs with the primary function of helping to remove toxins from the body and regulate water balance. They are vital to survival. After urine is produced in the kidneys, it must pass into the bladder, where it can be stored before being eliminated from the body through the urethra. Urinary tract obstruction is a common problem encountered by urologists, primary care physicians, and emergency medicine physicians. Urine can become obstructed at any point in this pathway. There are three groups of urinary tract obstructions: 1 obstruction of the urinary tract lumen; 2 obstruction of the urinary tract wall; and 3 extrinsic obstruction, which can press on the urinary tract lumen. An obstruction can be present from birth or develop later in life. The most common causes of obstruction include stones, strictures, tumours, and bladder dysfunction. These obstructions may result in the hydronephrosis of one or both kidneys, which, if left untreated, may lead to the deterioration of renal function. The goal of an initial treatment of urinary tract obstruction is to remove the obstruction. Later, we treat the cause that led to the obstruction. The bottom line is that all efforts should be made to preserve kidney function to avoid the need for dialysis or renal transplantation.

    Fetal bladder rupture is a rare complication occurring due to bladder outlet obstruction, mostly posterior urethral valves. A 26-year-old primigravida presented to us at 27 weeks gestation with an ultrasound report showing gross fetal ascitis and mild oligohydramnios. A repeat scan was performed which showed fetal bladder rupture and urinary ascitis. In conjunction with paediatric surgeon, we performed ultrasound-guided placement of double-ended pigtail catheter connecting the fetal peritoneal cavity with the amniotic cavity at 28 weeks gestation. Ultrasound performed 3 days after the placement of the catheter showed its correct placement. Unfortunately, 1 week after the procedure at 29 weeks gestation, the patient had premature rupture of membranes and later went into labour and delivered vaginally. The neonate could not be revived and expired after few hours of birth due to prematurity-related complications. The placement of the shunt could have probably precipitated preterm rupture of membranes. PMID:23946514

    , the internal pressure of the urethra should also increase. In women, the internal pressure of the urethra is short, and even if it has poorly developed they wet themselves when they cough. "nThe causes of BD: "nAs you see there are 17 causes, which 11 are related to the bladder. The bladder is responsible for retaining the urine and voiding. "nPathophysiology: "nThe bladder and sphincter should work in a coordinated manner: "nDuring the course of a day, an average person will void approximately 4-8 times. The urinary bladder is in storage mode for most of the day, allowing an individual to engage in more important activities than urination. "nNormal bladder function consists of 2 phases—filling and emptying. The normal micturition cycle requires the urinary bladder and the urethral sphincter working together as a coordinated unit to store and empty urine. During urinary storage, the bladder acts as a low-pressure receptacle, while the urinary sphincter maintains high resistance to urinary flow to keep the bladder outlet closed. During urine elimination, the bladder contracts to expel urine while the urinary sphincter opens (low resistance to allow unobstructed urinary flow and bladder emptying. "nFilling phase: "nDuring the filling phase, the bladder accumulates increasing volumes of urine while the pressure inside the bladder remains low. The pressure within the bladder must be lower than the urethral pressure during the filling phase. If the bladder pressure is greater than the urethral pressure (resistance, urine will leak out. "nThe filling of the urinary bladder depends on the intrinsic viscoelastic properties of the bladder and the inhibition of the parasympathetic nerves. Thus, bladder filling is primarily a passive event. "nSympathetic nerves also facilitate urine storage in the following ways: "nSympathetic nerves inhibit the parasympathetic nerves from triggering bladder contractions. "nSympathetic nerves directly cause relaxation and expansion of the

    Background Overactive bladder (OAB) can be caused by many factors such as inflammation,bladder outlet obstruction,neurogenic factors.We performed an intraperitoneal (ip) injection of cyclophosphamide to induce cystitis in rats,which causes their detrusors to overact,to provide a valuable disease model for discussing OAB pathogenesis and to study effective curing methods.Methods Female Sprague-Dawley rats were induced to form cystitis by cyclophosphamide (200 mg/kg,ip).The day after the injection,two catheters were inserted into each rat's bladder to study its urodynamics.The BL-410 model bio-function experimental system was used to monitor bladder pressure while the rats were conscious.Unstable detrusor contractions appear in the urine storage period as a standard to determine OAB,and the positive rate was calculated.Urodynamic parameters such as bladder basal pressure (BP),maximum voiding pressure (MVP),intercontraction interval (ICI),spontaneous activity (SA),maximum cystometric capacity (MCC),and bladder compliance (BC) were recorded in each group,and a light microscope was used to observe the pathological changes in the rat bladder tissue.Results The detrusor instability rate of the model group was 83.33%.The MVP,MCC and BC of rats in the model group were lower than the control group (P <0.01),and the BP,ICI and SA of the model group rats were higher than the control group (P <0.01).The difference between the control group and the model group is statistically significant.The model group rats' bladder walls swelled and bled,the submucosa thickened and leukocyte infiltration became serious.Conclusions Acute cystitis and OAB symptoms can be induced by ip injections of cyclophosphamide in rats.This can provide a valuable animal model to study OAB in human beings.

    Full Text Available Congenital anomalies such as meningomyelocele and diseases/damage of the central, peripheral, or autonomic nervous systems may produce neurogenic bladder dysfunction, which untreated can result in progressive renal damage, adverse physical effects including decubiti and urinary tract infections, and psychological and social sequelae related to urinary incontinence. A comprehensive bladder-retraining program that incorporates appropriate education, training, medication, and surgical interventions can mitigate the adverse consequences of neurogenic bladder dysfunction and improve both quantity and quality of life. The goals of bladder retraining for neurogenic bladder dysfunction are prevention of urinary incontinence, urinary tract infections, detrusor overdistension, and progressive upper urinary tract damage due to chronic, excessive detrusor pressures. Understanding the physiology and pathophysiology of micturition is essential to select appropriate pharmacologic and surgical interventions to achieve these goals. Future perspectives on potential pharmacological, surgical, and regenerative medicine options for treating neurogenic bladder dysfunction are also presented.

    Full Text Available Hepatobiliary ascariasis is commonly reported from highly endemic regions like India, Bangladesh, Latin America, parts of Middle East and Africa. In humans, the usual habitat of Ascaris lumbricoides is the small intestine. When the worm load is high, going as high as more than 1000 worms, then the worms tend to migrate away from the usual site. Patients with hepatobiliary ascariasis may present with biliary colic due to obstruction caused by the worms in the gall bladder, common bile duct or as a result of obstructive symptoms caused by calcified worms or lithiasis, which is commonly found in patients with hepatobiliary ascariasis. Acute pancreatitis may also be caused by ascariasis. Management usually is conservative if it is still alive or can be extracted by endoscopic retrograde cholangio-pancreatography or surgery.

  5. Cross-sectional and longitudinal studies on interaction between bladder compliance and outflow obstruction in men with benign Prostatic hyperplasia%前列腺增生男性膀胱顺应性与流出道梗阻间相互关系的横截面与纵向研究

    2007-01-01

    Aim:To explore the interaction between bladder compliance (BC) and bladder outflow obstruction (BOO) in men with benign prostatic hyperplasia (BPH) using cross-sectional and longitudinal studies. Methods: A total of 181 men with BPH were recruited, and 100 of them were followed for one year. Cystometry was performed in a standing or a sitting position with 30 mL/min infusion. BC was manually corrected and defined. Obstruction coefficient (OCO), linear passive urethral resistance relation and international continence society (ICS) nomogram were used to diagnose BOO. The obstructed parameters were compared between the reduced BC group and the non-reduced group. BC was compared between the first investigation at the beginning of study and the second investigation at the end of study during the one-year follow-up period. Results: The group with reduced BC had increased OCO and linear passive urethral resistance relation. BC was significantly lower in the obstructed group (55.7 mL/cm water) than that in unobstructed and equivocal one (74.9 mL/cm water, P < 0.01). BC gradually reduced with the increased obstructed grade. There was a significantly weak negative correlation between BC and OCO (r = - 0.132, P<0.01).Over the one-year follow-up period in the longitudinal study, BC for all men changed from 54.4 to 48.8 mL/cm water (P > 0.05), and BC for the group with BOO fell from 58.4 ± 70.1 to 46.5 ± 38.7 mL/cm water (P > 0.05). Conclusion:In men with BPH, a significant systematic decrease occurred in BC in the obstructed group and a significant systematic increase with urethral resistance occurred in the low BC group. A longitudinal study of the tendency of BC reduction in a group with BOO is necessary in the future.

    2011-01-01

    Objective To estimate the application of ultrasound measurement of detrusor wall thickness (DWT) in the assessment of curative effect after operation. Methods Detrusor thickness was measured by linear ultrasound (7. 5 MHz) either at a filling volume of 50% of cystometric capacity or at 250 ml filling in 86 patients, who were diagnosed equivocal BOO, during a pressure-flow study. All patients accepted transurethral resection of the prostate. At 3 months post-surgery, the patients were divided into two groups according to curative effect after operation. The volume of the prostate, age and DWT were compared between the two groups. Results There was no difference in either age or volume of the prostate between the two groups. DWT was significantly higher (P<0.01) in the more curative effect group (37 cases, DWT 2. 5±0.3 mm) compared to the less curative effect group (49 cases, 2.2±0. 3 mm). As a predictor of curative effect, DWT of 2. 8 mm or greater had a positive predictive value of 100%, a negative predictive value of 62%, specificity of 100% and sensitivity of 19%. Receiver operating characteristic analysis (ROC) revealed that DWT had a high predictive value for curative effect post-surgery with an AUC of 0. 84±0. 04. Conclusions In patients with equivocal BOO, ultrasonographically assessed detrusor thickness may have a predictive value for curative effect post-surgery. However, this cutoff value needs to be validated in a larger study population.%目的 分析可疑膀胱出口梗阻患者术前逼尿肌厚度,探讨逼尿肌厚度测定对可疑膀胱出口梗阻患者术后疗效的预测作用.方法 对可疑膀胱出口梗阻并行手术治疗的86例患者在行压力流率测定过程中,当膀胱容量为250 ml或灌注量为膀胱最大容量的50%时,应用7.5 MHz高频线纵超声探头行膀胱前壁逼尿肌厚度测定.术后3个月复查,将患者分为疗效显著组与疗效非显著组,比较2组患者年龄、前列腺体积及逼尿肌厚度.结果 疗效显著组(37例)与疗效非显著组(49例)患者年龄及前列腺体积差异无统计学意义(P>0.05).逼尿肌厚度差异有统计学意义[(2.5±0.3)和(2.2±0.3)mm,P<0.01].应用受试者工作特性曲线,当逼尿肌厚度≥2.8 mm时,逼尿肌厚度测定作为预测工作特异性和阳性预测值均为100%,而敏感性为19%,阴性预测值为62%.其曲线下面积为0.84±0.04.结论 逼尿肌测定预测可疑膀胱出口梗阻患者术后疗效可靠,但仍需要多中心、大样本的试验进一步确定临界值.

    In order to study the pathogenesis, clinical and pathological characteristics of prolifera-tive lesions of the bladder, 50 cases of proliferative lesions of the bladder from 150 patients withcomplaints of frequency, urgency, hematuria and dysuria were subjected to cystoscopic biopsy ofthe suspicious foci in the bladder. In combination with the symptoms, urine routine and urodynam-ics, the relationship of proliferative lesions of the bladder to the inflammation and obstruction of thelower urinary tract was analyzed. Of the 50 cases of proliferative bladder lesions, 44 cases (88%)had lower urinary tract infection and 29 (58%) lower urinary tract obstruction. The patients withlower urinary tract obstruction were all complicated with infection. Three cases were associatedwith transitional cell carcinoma. Malignant cells were detected in 1 case by urinary cytologic exami-nation. Proliferative lesions of the bladder, especially those without other obvious mucosa changesunder cystoscopy, are common histological variants of urothelium in the patients with chronic in-flammation and obstruction of the lower urinary tract. Chronic inflammation and obstruction of thelower urinary tract might be the causes for proliferative lesions of the bladder. It is suggested thatdifferent treatments should be applied according to the scope and histological type of the prolifera-tive lesions.

    Flushing pipe outlets are provided at the floor of sedimentation basins for flushing out of the deposited sediments. These outlets have to be positioned in such a way so as to remove the deposited sediments effectively. In the absence of rational method for the location, presently the outlets are located by judgment. A review of literature indicated that there is no judicious method available for obtaining the outlet diameter. Presented herein are the design equations for the flushing outlets. It is hoped that the equation will be useful to the design engineers.

    Full Text Available Waleed Al Taweel, Raouf SeyamDepartment of Urology, King Faisal Specialist Hospital and Research Center, Riyadh, Saudi ArabiaAbstract: Neurogenic bladder dysfunction due to spinal cord injury poses a significant threat to the well-being of patients. Incontinence, renal impairment, urinary tract infection, stones, and poor quality of life are some complications of this condition. The majority of patients will require management to ensure low pressure reservoir function of the bladder, complete emptying, and dryness. Management typically begins with anticholinergic medications and clean intermittent catheterization. Patients who fail this treatment because of inefficacy or intolerability are candidates for a spectrum of more invasive procedures. Endoscopic managements to relieve the bladder outlet resistance include sphincterotomy, botulinum toxin injection, and stent insertion. In contrast, patients with incompetent sphincters are candidates for transobturator tape insertion, sling surgery, or artificial sphincter implantation. Coordinated bladder emptying is possible with neuromodulation in selected patients. Bladder augmentation, usually with an intestinal segment, and urinary diversion are the last resort. Tissue engineering is promising in experimental settings; however, its role in clinical bladder management is still evolving. In this review, we summarize the current literature pertaining to the pathology and management of neurogenic bladder dysfunction in patients with spinal cord injury.Keywords: neurogenic bladder, spinal cord injury, urodynamics, intestine, intermittent catheterization

    2011-08-01

    Of the many clinical entities involving the neck region, one of the most intriguing is thoracic outlet syndrome (TOS). TOS is an array of disorders that involves injury to the neurovascular structures in the cervicobrachial region. A classification system based on etiology, symptoms, clinical presentation, and anatomy is supported by most physicians. The first type of TOS is vascular, involving compression of either the subclavian artery or vein. The second type is true neurogenic TOS, which involves injury to the brachial plexus. Finally, the third and most controversial type is referred to as disputed neurogenic TOS. This article aims to provide the reader some understanding of the pathophysiology, workup, and treatment of this fascinating clinical entity. PMID:21824588

  13. Percutaneous intervention in obstructive

    International Nuclear Information System (INIS)

    Percutaneous intervention procedures in obstructive uropathy include percutaneous nephrostomy tube placements, nephroureteral stents, percutaneous nephrostomy combined with ureteral embolization, percutaneous management of stone disease, suprapubic tube placements into the bladder, and perinephric/retroperitoneal urinomas/abscesses drainages. Percutaneous nephrostomy is performed to relieve urinary obstruction or divert the urinary stream away from the ureter or bladder. Patients are given preprocedure antibiotics. Percutaneous nephrostomies can be emergent cases because of risk of pyuria and sepsis from a stagnant urine collection. The procedure is performed using both ultrasound and fluoroscopy (or fluoroscopy alone using anatomic landmarks, or an internal radiopaque calculus, or delayed phase excretion of the contrast into the renal collecting system) under local anesthesia or conscious sedation. Ureteral stents are placed to bypass an obstructing stone or to stent across of an area of stricture or ureteral laceration. Stents may be placed by the urologist via a transurethral approach or by the interventional radiologist via a percutaneous approach. The decision as to method of stent placement is based upon the location and accessibility of the ureteral pathology. Ureteral embolization is performed in patients with unresectable tumors of the pelvis with long-standing nephrostomy tubes and distal urine leaks refractory to other treatments. Coils, gelfoam and liquid embolic materials can be used. Ureteral embolization for ureteral fistulas and incontinence is technically successful in 100% of the patients. Complications include bleeding, infection, ureteral or renal injury, and deployment (or movement) of the coils within the renal pelvis. Percutaneous management of stone disease, including renal, ureteral, and bladder stones requires close cooperation between the urologist and interventional radiologist, because of availability of sonographic lithotripsy

    Bladder rupture following caesarian section is well documented complications. Intraperitoneal bladder rupture following normal vaginal delivery is very rare. Hereby, we present a case report of intraperitoneal bladder rupture presented late following normal vaginal delivery. We report a case of spontaneous intraperitoneal urinary bladder rupture following uneventful outlet forceps delivery in a 22-year-old primi gravid woman with gestational diabetes mellitus and fetal macrosomia who presented with large urinary ascites, anuria and renal failure. Emergent exploratory laparotomy with repair of the intraperitoneal bladder rupture helped to prevent its potential complications. Postpartum patients who undergo episiotomy or perineal repair may land up in unnoticed urinary retention which may rarely terminate in spontaneous urinary bladder rupture. Awareness of its manifestations amongst emergency physician would help to initiate appropriate timely management. PMID:26557563

    Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. PMID:27247718

  17. Analysis of failure following definitive radiotherapy for invasive transitional cell carcinoma of the bladder

    International Nuclear Information System (INIS)

    Purpose: To assess prognostic factors for bladder relapse and distant failure following definitive radiotherapy for invasive transitional cell carcinoma (TCC) of the bladder. Methods and Materials: Retrospective review of patients treated in the period 1977 to 1990 by definitive radiotherapy. The factors studied included age, sex, T stage, histological grade, tumor multiplicity, ureteric obstruction, total radiation dose, and use of neoadjuvant chemotherapy. The endpoints studied were bladder relapse and distant failure. Results: There were 342 patients with a mean follow-up time of 7.9 years. Bladder relapse was observed in 159 patients. The overall actuarial bladder relapse rate at 5 years was 55% (SE = 3%). Prognostic factors for a higher bladder relapse rate were: tumor multiplicity (p < 0.001), presence of ureteric obstruction (p = 0.001), and higher T stage (p 0.044). Distant failure occurred in 39 patients. The overall actuarial distant failure rate at 5 years was 28% (SE = 3%). Prognostic factors for a higher distant failure rate were: ureteric obstruction (p = 0.003) and higher T stage (p = 0.030). Conclusion: In our study, patients with invasive bladder TCC fell into distinct prognostic groups determined by the three independent factors, ureteric obstruction, tumor multiplicity, and T stage. These factors provided estimated risks of bladder relapse by 5 years which ranged from 34% to 91%. Knowledge of these prognostic factors can help in the selection of patients more suited for bladder preservation by definitive radiotherapy

    To evaluate the risk for kidney damage in a male fetus with obstructive uropathy, a percutaneous bladder puncture was performed at 26 weeks gestational age and contrast was injected into the fetal bladder. A clear picture was obtained of the bladder with marked widening of the prostatic urethra and posterior urethral valves, and massive bilateral vesicoureteral reflux could be demonstrated. By adding cysto-urethrography to a diagnostic puncture of the fetal bladder it could be proved that the dilatation of the upper urinary tracts was caused by high-pressure vesico-urethral reflux incurring progressive damage to the renal parenchyma.

    @@ Double outlet ventricle (DOV) is defined as a congenital heart disease with: (1) both great arteries arising completely, or almost completely (≥90%), from a single ventricle (usually, right ventricle); (2) an aortic valve having no fibre connection with mitral valve; and (3) the only outlet of the other ventricle is a ventricular septal defect (VSD). The incidence of DOV accounts for 1% of all congenital heart disease.1 Clinically there are three common types: Fallot type or double outlet right ventricle (DORV) with subaortic VSD with pulmonary stenosis; Eisenmenger type or DORV with subaortic VSD without pulmonary stenosis and Taussig-Bing type or DORV with subpulmonary VSD. Operative techniques are different according to the position of the VSD and great arteries and the presence or absence of ventricular outflow tract obstruction. The operative difficulty increases in the presence of coronary artery malformation. Recently, our research centre has treated 72 cases of patients suffering from double outlet ventricle. This article is the report of the operative methods and the outcomes.

    Richard, Patrick; Ordonez, Nydia Icaza; Tu, Le Mai

    2013-01-01

    Objectives: Our objective was to evaluate the effect of a 6 Fr transurethral catheter on the uroflowmetry and to assess whether it potentially contributes to the bladder outlet obstruction (BOO) in women. Methods: We reviewed the charts of 1367 women who underwent an urodynamic study. We included patients with a non-invasive free-flow study (NIFFS) and pressure flow study (PFS) performed through a 6 Fr double lumen transurethral catheter. Results: In total, 120 women met the inclusion/exclusion criteria. Mean maximal flow rate (Qmax) was significantly higher (p 12 mL/s during the NIFFS. Of the 10 patients, only 2 reported obstructive symptoms. Conclusion: The presence of 6 Fr transurethral catheters alters the PFS and results in a significant reduction of the Qmax in patients who voided more than 250 mL. We believe that NIFFS should be performed in all patients before any urethral manipulation to lower a possible overdiagnosis of BOO and findings should always be correlated to clinical symptoms.

  5. Unusual causes of mechanical small bowel obstruction

    International Nuclear Information System (INIS)

    We herein report our experience regarding unusual causes of bowel obstruction to increase the awareness of surgeons regarding this disease. From 1991 to 2003, we had experience at the University affiliated hospitals, northern Jordan with 24 patients with small bowel obstruction resulting from unusual causes. We retrospectively reviewed the medical records of these patients with regards to the mode of presentation, cause of obstruction, radiological and operative findings, management and outcome. We recorded 15 patients who underwent previous abdominal surgery. Preoperative diagnosis was correct in only one patient with an internal hernia, but the abdominal CT scan suggested the diagnosis in 5 of the 9 patients who had the scan. The final diagnosis was internal hernias in 11 patients, foreign bodies in 5, ischemic strictures in 3, carcinoid tumors in 2, endometriosis in 2, and metastatic deposit from interstitial bladder carcinoma in one patient. Nine of the 12 patients with recurrent obstruction had either short course or recurrence obstruction during the same hospital admission. W carried out bowel resections in 15 patients (5 resections were due to bowel strangulation). Post operative death occurred in 4 patients. Awareness of these rare causes of intestinal obstruction even in patients with previous abdominal operation might improve the outcome. The tentative diagnosis of adhesion obstruction in patients with unusual obstructive etiology might lead to a higher rate of gangrenous complications. Rigorous preoperative evaluation including careful history and early abdominal CT may show the obstructive cause. (author)

    Purpose: Recent investigations described the use of NGAL, a sensitive biomarker for kidney injury, in the setting of ureteropelvic junction obstruction. We prospectively evaluated urinary NGAL levels in the affected renal pelvis and bladder of children with ureteropelvic junction obstruction undergoing unilateral dismembered pyeloplasty. Our hypothesis was that higher NGAL in the kidney and bladder would correlate with decreased ipsilateral differential function. Materials and Methods: We performed a prospective cohort study in patients treated with unilateral dismembered pyeloplasty from 2010 to 2012. Urine was obtained intraoperatively from the bladder and obstructed renal pelvis. A control population of unaffected children was recruited to provide a voided bladder specimen. Bladder NGAL levels were compared between the study and control populations. We tested our study hypothesis by correlating bladder and renal pelvic NGAL levels with the differential renal function of the affected kidney. Results: A total of 61 patients with a median age at surgery of 1.62 years (range 0.12 to 18.7) were enrolled in the study. Median bladder NGAL was 18.6 ng/mg (range 1.4-1,650.8) and median renal pelvic NGAL was 26.2 ng/mg (range 1.2-18,034.5, p = 0.004). Median bladder NGAL was significantly higher than in controls (p = 0.004). The correlation of bladder and renal pelvic NGAL with differential renal function was r = −0.359 (p = 0.004) and r = −0.383 (p = 0.002), respectively. Conclusions: Bladder NGAL is increased in children with ureteropelvic junction obstruction. Renal pelvic and bladder normalized urinary NGAL levels correlate inversely with the relative function of the affected kidney in cases of unilateral ureteropelvic junction obstruction. PMID:23791906

    2004-01-01

    Objective: To investigate the clinicopathologic features and diagnostic criteria of urachal carcinoma in the bladder.Methods: Seven cases of urachal carcinoma in the bladder were analyzed retrospectively. Results: All the tumors were found locating in the dome of bladder. Of them, 4 were mucinous adenocarcinoma, one was well differentiated papillary enteric adenocarcinoma, one was well differentiated squamous carcinoma, and one was neuroendocrine carcinoma. Cystomorphous urachal remnants were found in 4 cases. The main complaint was hematuria and all patients underwent partial excision of bladder and urachus. Conclusion: Mucinous adenocarcinoma is the main histo-pathological type, and cystomorphous urachal remnants are often accompanied with urachal carcinoma in the bladder. The key diagnostic criteria of urachal carcinoma in bladder are site and histopathology. And to examine the specimens carefully to find the urachal remnants is important.

    1979-04-01

    The treatment of urologic complications from myelomeningocele and especially of vesico-renal reflux is a controversial problem. A series of 26 reimplanted ureters in 17 children, with good results in more than 85%, is reported. Ureteroneocystostomy, carried out with a few technical innovation, may represent a useful method for the treatment of vesico-renal reflux and obstruction of the uretero-vesical junction in neurogenic bladder associated with myelomeningocele. This surgical approach leads to the disappearance of the reflux, decrease of dilatation of the upper urinary tract and preservation of renal function in most cases; moreover, infection can be more easily controlled. Ureteral reimplantation should be preceded by periodic urethral dilatation, external transurethral sphincterotomy, and pharmacologic regulation in order to attempt to decrease urethral resistance. After successful surgery, it is possible to try to reeducate the bladder. Reimplantation should be preferred to permanent urinary diversion even if there is gross reflux. PMID:458534

    Full Text Available A phytobezoar is one of the intraluminal causes of gastric outlet obstruction, especially in patients with previous gastric surgery and/or gastric motility disorders. Before the proton pump inhibitor era, vagotomy, pyloroplasty, gastrectomy and gastrojejunostomy were commonly performed procedures in peptic ulcer patients. One of the sequelae of gastrojejunostomy is phytobezoar formation. However, a bezoar causing gastric outlet obstruction is rare even with giant gastric bezoars. We report a rare case of gastric outlet obstruction due to a phytobezoar obstructing the efferent limb of the gastrojejunostomy site. This phytobezoar which consisted of a whole piece of okra (lady finger vegetable was successfully removed by endoscopic snare. To the best of our knowledge, this is the first case of okra bezoar-related gastrojejunostomy efferent limb obstruction reported in the literature.

    2004-05-01

    The aim of this study was to evaluate the appearance of the upper urinary tract following cystectomy and ileal orthotopic bladder substitution. Intravenous urograms (IVUs) performed preoperatively and at regular intervals postoperatively on 87 long-term survivors (minimum survival, 5 years) following ileal orthotopic bladder substitution were reviewed. Distention of the collecting system with blunted or rounded fornices was defined as dilatation. If in addition contrast medium excretion was delayed on the 5-min film, this was defined as obstruction. Collecting system dilatation was present on all IVU films obtained from most patients (80%) within 6 months of surgery, even in the absence of urinary tract obstruction. In contrast, dilatation was commonly seen only on the 20-min postinjection films (79%) on urograms performed more than 1 year following surgery, but not encountered on the other two postinjection radiographs (at 5 and 60 min). Five years after surgery, permanent obstruction was observed in only five (3%) renoureteral units. Dilatation of the upper urinary tract after ileal orthotopic bladder substitution is a frequent finding on the 5-min, 20-min, and 60-min films during the early postoperative period but is found only on the 20-min film 1 year and later after surgery. These findings should not be overinterpreted as obstruction. (orig.)

  5. Alcohol outlets and clusters of violence

    2011-05-01

    Full Text Available Abstract Background Alcohol related violence continues to be a major public health problem in the United States. In particular, there is substantial evidence of an association between alcohol outlets and assault. However, because the specific geographic relationships between alcohol outlets and the distribution of violence remains obscured, it is important to identify the spatial linkages that may exist, enhancing public health efforts to curb both violence and morbidity. Methods The present study utilizes police-recorded data on simple and aggravated assaults in Cincinnati, Ohio. Addresses of alcohol outlets for Cincinnati, including all bars, alcohol-serving restaurants, and off-premise liquor and convenience stores were obtained from the Ohio Division of Liquor Control and geocoded for analysis. A combination of proximity analysis, spatial cluster detection approaches and a geographic information system were used to identify clusters of alcohol outlets and the distribution of violence around them. Results A brief review of the empirical work relating to alcohol outlet density and violence is provided, noting that the majority of this literature is cross-sectional and ecological in nature, yielding a somewhat haphazard and aggregate view of how outlet type(s and neighborhood characteristics like social organization and land use are related to assaultive violence. The results of the statistical analysis for Cincinnati suggest that while alcohol outlets are not problematic per se, assaultive violence has a propensity to cluster around agglomerations of alcohol outlets. This spatial relationship varies by distance and is also related to the characteristics of the alcohol outlet agglomeration. Specifically, spatially dense distributions of outlets appear to be more prone to clusters of assaultive violence when compared to agglomerations with a lower density of outlets. Conclusion With a more thorough understanding of the spatial relationships

    The Greenland Ice Sheet is losing mass at an accelerating rate due to increased surface melt and flow acceleration in outlet glaciers. Quantifying future dynamic contributions to sea level requires accurate portrayal of outlet glaciers in ice sheet simulations, but to date poor knowledge of subglacial topography and limited model resolution have prevented reproduction of complex spatial patterns of outlet flow. Here we combine a high-resolution ice-sheet model coupled to uniformly applied models of subglacial hydrology and basal sliding, and a new subglacial topography data set to simulate the flow of the Greenland Ice Sheet. Flow patterns of many outlet glaciers are well captured, illustrating fundamental commonalities in outlet glacier flow and highlighting the importance of efforts to map subglacial topography. Success in reproducing present day flow patterns shows the potential for prognostic modelling of ice sheets without the need for spatially varying parameters with uncertain time evolution.

    2016-05-23

    Bladder cancer, one of the most frequently occurring human cancers, develops via two tracks referred to as papillary and nonpapillary that correspond to clinically different forms of the disease. Most bladder cancers are chemically induced, with tobacco smoking being the leading risk factor. Recent advances in bladder cancer research have enhanced our understanding of the origin of this disease from urothelial progenitor cells via field effects along papillary/luminal and nonpapillary/basal pathways. Evident from the outset of the disease, the diversity of the luminal and basal pathways, together with cell lineage tracing studies, postulates the origin of molecularly distinct subtypes from different uroprogenitor cells. The molecular mechanisms initiating field effects involve a new class of genes referred to as forerunner (FR) genes that generally map around major tumor suppressors such as RB1. These genes are silenced, predominantly by hypermethylation and less frequently by mutations, and drive the expansion of intraurothelial preneoplastic cells. Different FR genes are involved in various molecular subtypes of bladder cancer and they sensitize the uroprogenitor cells to the development of luminal and basal bladder cancers in animal models. In human bladder cancer, luminal and basal forms have dissimilar clinical behavior and response to conventional and targeted chemotherapeutic manipulations. These new research developments hold the promise of expanding our armamentarium of diagnostic and treatment options for patients with bladder cancer and improving our ability to select patients most likely to respond to a specific therapy.

    Eleven patients with an obstructed, fluid-filled uterus, due to carcinoma of the uterus or to its treatment by radiation therapy, were examined with computed tomography (CT) and/or ultrasound. It is important to recognize this abnormality to differentiate it from other causes of pelvic mass and to ensure prompt treatment of pyometra, should it develop. Both CT and ultrasound reliably identified this condition and differentiated it from other pelvic masses.

  13. Congenital urinary tract obstruction: the long view.

    Science.gov (United States)

    Chevalier, Robert L

    2015-07-01

    Maldevelopment of the collecting system resulting in urinary tract obstruction (UTO) is the leading identifiable cause of CKD in children. Specific etiologies are unknown; most cases are suspected by discovering hydronephrosis on prenatal ultrasonography. Congenital UTO can reduce nephron number and cause bladder dysfunction, which contribute to ongoing injury. Severe UTO can impair kidney growth in utero, and animal models of unilateral ureteral obstruction show that ischemia and oxidative stress cause proximal tubular cell death, with later development of interstitial fibrosis. Congenital obstructive nephropathy, therefore, results from combined developmental and obstructive kidney injury. Because of inadequacy of available biomarkers, criteria for surgical correction of upper tract obstruction are poorly established. Lower tract obstruction requires fetal or immediate postnatal intervention, and the rate of progression of CKD is highly variable. New biomarkers based on proteomics and determination of glomerular number by magnetic resonance imaging should improve future care. Angiotensin inhibitors have not been effective in slowing progression, although avoidance of nephrotoxins and timely treatment of hypertension are important. Because congenital UTO begins in fetal life, smooth transfer of care from perinatologist to pediatric and adult urology and nephrology teams should optimize quality of life and ultimate outcomes for these patients.

    1993-02-01

    Since the initiation of staged reconstruction for bladder exstrophy, hypertension has been a known complication of the procedure. The etiology of the elevation in blood pressure was presumably secondary to ureteral dysfunction caused by edema at the ureterovesical junction and secondary renal obstruction. This report details the clinical course of three patients who developed significant hypertension following primary bladder closure with posterior iliac osteotomies and bony immobilization by skin traction. None of the patients had urinary obstruction and all had their hypertension alleviated by removal of the traction. The presumed etiology of the elevated blood pressure within these patients is similar to that experimentally produce by inappropriately applied traction resulting in tension on the sciatic nerve and reflex induced vasoconstriction. The need to maintain appropriately applied traction and the necessity of monitoring the postoperative blood pressure is stressed. PMID:8155094

    2014-03-01

    Full Text Available Foreign bodies in the bladder are rarely observed because of difficult access. These patients usually have a mental disorder, a background of intense sexual perversion, or inquisitiveness. A 48-year-old, deaf, and mentally retarded woman was referred to the nephrology clinic for severe anemia and impaired renal function. Imaging tests showed a mercury thermometer positioned in the bladder and a stone, 5 cm in diameter, around it. This had caused bilateral ureteral obstruction. The patient underwent an open cysteotomy. Obstructive uropathy is one of the causes of kidney failure; therefore, foreign bodies should be included in the differential diagnosis.

    2015-01-01

    Objective: Alcohol outlets tend to be located in lower income areas, exposing lower income populations to excess risks associated with alcohol sales through these establishments. The objective of this study was to test two hypotheses about the etiology of these differential exposures based on theories of the economic geography of retail markets: (a) outlets will locate within or near areas of high alcohol demand, and (b) outlets will be excluded from areas with high land and structure rents. Method: Data from the 2010 National Drug Strategy Household Survey were used to develop a surrogate for alcohol demand (i.e., market potential) at two census geographies for the city of Melbourne, Australia. Bayesian conditional autoregressive Poisson models estimated multilevel spatial relationships between counts of bars, restaurants, and off-premise outlets and market potential, income, and zoning ordinances (Level 1: n = 8,914). Results: Market potentials were greatest in areas with larger older age, male, English-speaking, high-income populations. Independent of zoning characteristics, greater numbers of outlets appeared in areas with greater market potentials and the immediately surrounding areas. Greater income excluded outlets in local and surrounding areas. Conclusions: These findings are consistent with the hypothesis that alcohol outlets are located in areas with high demand and are excluded from high-income areas. These processes appear to take place at relatively small geographic scales, encourage the concentration of outlets in specific low-income areas, and represent a very general economic process likely to take place in communities throughout the world.

  18. Invasive bladder cancer: treatment strategies using transurethral surgery, chemotherapy and radiation therapy with selection for bladder conservation

    International Nuclear Information System (INIS)

    Purpose: Combined modality therapy has become the standard oncologic approach to achieve organ preservation in many malignancies. Methods and Materials: Although radical cystectomy has been considered as standard treatment for invasive bladder carcinoma in the United States, good results have been recently reported from several centers using multimodality treatment, particularly in patients with clinical T2 and T3a disease who do not have a ureter obstructed by tumor. Results: The components of the combined treatment are usually transurethral resection of the bladder tumor (TURBT) followed by concurrent chemotherapy and radiation therapy. Following an induction course of therapy a histologic response is evaluated by cystoscopy and rebiopsy. Clinical 'complete responders' (tumor site rebiopsy negative and urine cytology with no tumor cells present) continue with a consolidation course of concurrent chemotherapy and radiation. Those patients not achieving a clinical complete response are recommended to have an immediate cystectomy. Individually the local monotherapies of radiation, TURBT, or multidrug chemotherapy each achieve a local control rate of the primary tumor of from 20 to 40%. When these are combined, clinical complete response rates of from 65 to 80% can be achieved. Seventy-five to 85% of the clinical complete responders will remain with bladders free of recurrence of an invasive tumor. Conclusions: Bladder conservation trials using combined modality treatment approaches with selection for organ conservation by response of the tumor to initial treatment report overall 5-year survival rates of approximately 50%, and a 40-45% 5-year survival rate with the bladder intact. These modern multimodality bladder conservation approaches offer survival rates similar to radical cystectomy for patients of similar clinical stage and age. Bladder-conserving therapy should be offered to patients with invasive bladder carcinoma as a realistic alternative to radical

    Background For muscle invasive bladder cancer,radical cystectomy is the most effective treatment now and urinary diversion is often necessary.The use of intestinal tissue for urinary diversion is frequently associated with complications.In this study,we aimed to make a tissue-engineered conduit (TEC) using bladder epithelial cells and bladder acellular matrix (BAM) for urinary diversion in rabbits.Methods Bladder epithelial cells of rabbit were cultivated and expanded in vitro,then seeded on BAM,and cultured for 7 days.Then cell-seeded graft was used to make TEC.In the experimental group,most of bladder of the rabbit was removed while bladder trigone was retained.The proximal end of TEC was anastomosed with bladder trigone and the distal end was anastomosed with the abdominal stoma.In the control group,TEC was made using unseeded BAM.Haematoxylin and eosin staining was conducted,respectively,at 1,2,4,and 8 weeks postoperatively.Immunohistochemistry was performed 8 weeks postoperatively.Intravenous urography,retrograde pyelography,and cystoscopy of TEC were made at 12 weeks postoperatively.Results All animals were alive in the experimental group.Haematoxylin and eosin staining showed epithelial coverage in TEC.Immunohistochemistry showed anti-cytokeratin AE1/AE3 antibody and anti-ZO1 antibody positive,confirming there were mature and functional epithelial cells on the lumen of TEC.Retrograde pyelography and intravenous urography showed that TEC developed well and that there was no obstruction.In the control group,four rabbits were dead within 2 weeks and scar formation,atresia,and severe hydronephrosis were found.Conclusions We successfully made TEC using BAM and bladder epithelial cells for urinary diversion in rabbits.The lumen of this new TEC covered mature epithelial cells and could prevent urinary extravasation.

  20. Alcohol outlets, social disorganization, and robberies: accounting for neighborhood characteristics and alcohol outlet types.

    2015-05-01

    We estimated spatially lagged regression and spatial regime models to determine if the variation in total, on-premise, and off-premise alcohol outlet(1) density is related to robbery density, while controlling for direct and moderating effects of social disorganization.(2) Results suggest that the relationship between alcohol outlet density and robbery density is sensitive to the measurement of social disorganization levels. Total alcohol outlet density and off-premise alcohol outlet density were significantly associated with robbery density when social disorganization variables were included separately in the models. However, when social disorganization levels were captured as a four item index, only the association between off-premise alcohol outlets and robbery density remained significant. More work is warranted in identifying the role of off-premise alcohol outlets and their characteristics in robbery incidents. PMID:25769858

    Aromatic amines, including 2-naphthylamine, 4-aminobiphenyl and benzidine, are known urinary bladder carcinogens in man and other species, but in rodents, aromatic amines and amides have usually induced liver tumors, occasionally also with tumors of the bladder and other tissues. Variations in organ specificity are related to differences in metabolism; for the production of bladder tumors, the rates of acetylation and deacetylation appear to be critical. Bladder specific carcinogens in rodent...

    Full Text Available INTRODUCTION Gall bladder cancer is 5th most common cancer of GIT. It is associated with cholelithiasis in significant number of patients. Cholelithiasis is cause or effect of gall bladder cancer is still uncertain. There are many risk factors which are common to both gall stones and cancer. Preoperative diagnosis of gall bladder cancer is increased with better and new investigation facilities. AIM The study was aimed to assess clinicopathological behaviour, sociodemography, diagnostic modalities and treatment of cancer gall bladder. MATERIAL AND METHODS It was a type of prospective study which included 75 patients with clinical features suggestive of biliary disease. Various diagnostic modalities and treatment options were assessed along with sociodemography and clinical picture. RESULT Common clinical features were pain abdomen, obstructive jaundice and lump. Nearly one third of the patients were having anaemia and abnormal liver function tests. Majority had gall bladder fossa mass with liver extension and gall stones. The most common histopathological variety of carcinoma Gallbladder was Adenocarcinoma. CONCLUSION Carcinoma Gallbladder was found to affect predominantly the older female patients after the age of 40 years. Cholelithiasis was found in 69.3% patients of carcinoma Gallbladder. The most common clinical presentation was pain abdomen (90.7%. The most common histopathological variety of carcinoma Gallbladder was Adenocarcinoma. Majority of patients were treated with palliative measures.

    Ureteral obstruction and anastomotic leak represent the most common urologic complications of kidney transplantation. Delay in diagnosis or treatment can lead to allograft loss. Obstruction of the ureter occurs in 2% of kidney transplant recipients. Although the majority of cases are immediate technical complications of the operation, subsequent manipulation of the genitourinary system can result in iatrogenic ureteral injury. We report the case of a long-term kidney transplant recipient who developed obstructive uropathy and acute renal failure requiring dialysis after undergoing cystoscopy and bladder polyp fulguration. The etiology was inadvertent thermal injury of the ureteroneocystostomy incurred during the procedure. After attempted percutaneous management, definitive open repair resulted in a return of allograft function to baseline. Images Figure 1 Figure 2 PMID:15779509

  6. Gastric cancer and obstructive uropathy

    International Nuclear Information System (INIS)

    In recent 5 years, we have experienced 24 cases of advanced gastric cancer associated with obstructive uropathy. Included were 19 cases of undifferentiated, 3 cases of differentiated and 2 cases of unknown histological type. Obstructive uropathy is diagnosed based on the typical radiological findings such as dilatation and delayed demonstration of the upper collecting systems. Pathologically, undifferentiated type of gastric cancer had tendency to spread infiltratively along the vessels, nerves and the lymphatics without alteration of the ordinary anatomical structures. In such cases, mucosal surface of the urinary tract tended to be spared in spite of extensive tumor invasion. It was proven that several radiological findings were characteristic of urinary tract involvement secondary to gastric cancer. Either thread-like ureteral stricture by IVU or ring-like appearance of the ureter by CT is one of those typical findings. Renal sinus involvement may occur continuously to diffuse retroperitoneal invasion and it appears as a thickened wall of renal pelvis or soft tissue mass directly extending into the fatty tissue of renal sinus by CT. In such cases IVU has less diagnostic ability because of the lack of mucosal destruction. If the urinary bladder is involved, it typically shows chestnut-bur appearance by IVU and diffuse wall thickening by CT. In cases of advanced gastric cancer, particularly in cases of histologically undifferentiated type, CT and IVU images should be carefully interpreted in consideration of the infiltrative part of tumor extention.

  8. Computerized tomography and staging of bladder tumors

    International Nuclear Information System (INIS)

    Computed Tomography (CT) has been employed in 13 patients with bladder tumors; 8 of them subsequently underwent surgery. Concordance between CT and pathological staging ranged in 90% of accurate results. Our data are discussed and compared to those of other authors in the literature. Staging was carried out according to the International Union Against Cancer. CT proved to be very accurate in the assessment of local and regional spread of tumor, limphatic progression and early detection of ureteral obstruction, as well as diagnosis of distant metastasis in selected patients. In poor candidates for surgery CT provided invaluable data to be used for localizing fields of radiation therapy. CT is a very well tolerated procedure, it is therefore suitable in subsequent treatment control. (Author)

    Background In patients with neurogenic bladder (NB), elevated intravesical pressures can be transmitted to the upper urinary tract, causing hydronephrosis (HN) and ureteral dilation (UD), which are referred to as upper urinary tract dilation (UUTD). Ureteral obstruction at the bladder wall is another cause for UUTD, but is less of a concern. UUTD can lead to chronic renal failure. Therefore, evaluation and protection of UUT function is extremely important in the management for NB. Currently, ...

  12. Prognostic factors in invasive bladder carcinoma treated by combined modality protocol (organ-sparing approach)

    International Nuclear Information System (INIS)

    Purpose: The results of bladder sparing approach for the treatment of muscle-invasive bladder cancer, using a combination of transurethral resection (TUR), chemotherapy, and radiotherapy, are encouraging. The survival of patients treated by this method is similar to the survival of patients treated by radical cystectomy. The aim of our study was to find out which pretreatment characteristics influence the survival of patients treated by organ sparing approach that would enable us to identify the patients most suitable for this type of treatment. Methods and Materials: The prognostic value of different factors, such as age, gender, performance status, hemoglobin level, clinical stage, histologic grade, presence of obstructive uropathy, and completeness of TUR, has been studied in 105 patients with invasive bladder cancer, who received a bladder sparing treatment in the period from 1988 to 1995. They were treated with a combination of TUR, followed by 2-4 cycles of methotrexate, cisplatinum, and vinblastine polychemotherapy. In complete responders the treatment was completed by radiotherapy (50 Gy to the bladder and 40 Gy to the regional lymph nodes), whereas nonresponders underwent cystectomy whenever feasible. Results: Our study has confirmed an independent prognostic value of performance status, histologic grade, and obstructive uropathy, for the disease-specific survival (DSS) of bladder cancer patients treated by a conservative approach. We believe that performance status best reflects the extent of disease and exerts significant influence on the extent and course of treatment, while obstructive uropathy is a good indicator of local spread of the disease, better than clinical T-stage. Our finding that histologic grade is one of the strongest prognostic factors shows that tumor biology also is a very important prognostic factor in patients treated by conservative approach. Conclusion: Patients with muscle-invasive bladder cancer who are most likely to benefit

    A 77-year-old man presented with acute graft dysfunction 25 years after a renal transplant in the left iliac fossa. He also had an asymptomatic left inguinal hernia. Renal ultrasound showed a significant pyelocalicial dilation of the kidney graft and the patient was submitted to a percutaneous nephrostomy. An antegrade nephrostogram was performed, which showed a dilated ureter and the bladder included in the left inguinal hernia that caused the obstructive uropathy. Concomitant retrograde cystography also showed a significant portion of the bladder in the hernia sac. The patient was submitted to inguinal hernia repair, which resolved the obstruction. We present a rare and potentially curable cause of obstructive uropathy in a transplant recipient; it is possible to revert graft dysfunction and prevent graft loss if the condition is recognised early.

    A seventy two year old man presented to the Emergency Department with clinical features of colonic obstruction. Subsequent radiological investigations confirmed this impression and revealed the aetiology to be compression of the sigmoid colon against the sacrum by a massively distended urinary bladder. Chronic urinary retention due to benign prostatic hypertrophy is an extremely unusual cause of large bowel obstruction. Little in this patient\\'s clinical findings suggested this aetiology. We reviewed the literature in this area and highlight the benefits of CT scanning over contrast studies.

    Full Text Available We report a rare case of iliac vein compression syndrome caused by urethral calculus. A 71-year-old man had a history of urethral stenosis. He complained of bilateral leg edema and dysuria for 1 week. Physical examination revealed bilateral distention of the superficial epigastric veins, so obstruction of both common iliac veins or the inferior vena cava was suspected. Plain abdominal computed tomography showed a calculus in the pendulous urethra, distention of the bladder (as well as the right renal pelvis and ureter, and compression of the bilateral common iliac veins by the distended bladder. Iliac vein compression syndrome was diagnosed. Bilateral iliac vein compression due to bladder distention (secondary to neurogenic bladder, benign prostatic hyperplasia, or urethral calculus as in this case is an infrequent cause of acute bilateral leg edema. Detecting distention of the superficial epigastric veins provides a clue for diagnosis of this syndrome.

    Leaking or defective welded joints of tube plate outlets encountered during nuclear installation operation must be repaired. A method is suggested in which the defective tube plate outlets are first sealed below the cutting site to protect the tube plate from the penetration of dirt and then cut off. The remaining part of the tubes is cleaned. Extension tubes are then welded using argon arc electrode welding. They are shortened to required lengths and the cleaned tube plate is removed. The tube ends shall be calibration rolled and welded manually in two passes with a non-melting electrode using argon arc welding, the first pass without, the second pass with a filler wire. The ends of the tubes shall then be closed by rolling, leak tests shall be conducted and the plugs removed. (M.D.)

    To evaluate the feasibility and clinical effectiveness of using a polyurethane-covered expandable nitinol stent in the palliative treatment of malignant duodenal obstruction. Under fluoroscopic guidance, a polyurethane-covered expandable nitinol stent was placed in 12 consecutive patients with malignant duodenal obstructions. All presented with severe nausea and recurrent vomiting. The underlying causes of obstruction were duodenal carcinoma (n=4), pancreatic carcinoma (n=4), gall bladder carcinoma (n=2), distal CBD carcinoma (n=1), and uterine cervical carcinoma (n=1). The sites of obstruction were part I (n=1), part II (n=8), and III (n=3). Due to pre-existing jaundice, eight patients with part II obstructions underwent biliary decompression prior to stent placement. An introducer sheath with a 6-mm outer diameter and stents 16 mm in diameter were employed, and to place the stent, and after-loading technique was used. Stent placement was technically successful in ten patients, and no procedural complications occuured. In one of two patients in whom there was technical failure, and in whom the obstructions were located in part III, the stent was placed transgastrically. Stent migration occurred in one patient four days after the procedure, and treatment involved the palcement of a second, uncovered, nitinol stent. After stent placement, symptoms improved in all patients. During follow-up, obstructive symptoms due to stent stenosis (n=1), colonic obstruction (n=1), and multiple small bowel obstruction (n=1) recurred in three patients. Two of these were treated by placing additional stents in the duodenum and colon, respectively. One of the eight patients in whom a stent was placed in the second portion of the duodenum developed jaundice. The patients died a mean 14 (median, 9) weeks after stent placement. The placement of a polyurethane-covered expandable nitinol stent seems to be technically feasible, safe and effective for the palliative treatment of malignant

  7. Stratification in SNR-300 outlet plenum

    International Nuclear Information System (INIS)

    In the inner outlet plenum of the SNR-300 under steady state conditions a large toroidal vortex is expected. The main flow passes through the gap between dipplate and shield vessel to the outer annular space. Only 3% of the flow pass the 24 emergency cooling holes, situated in the shield vessel. The sodium leaves the reactor tank through the 3 symmetrically arranged outlet nozzles. For a scram flow rates and temperatures are decreased simultaneously, so it is expected, that stratification occurs in the inner outlet plenum. A measure of stratification effects is the Archimedes Number Ar, which is the relation of buoyancy forces (negative) to kinetic energy. (The Archimedes Number is nearly identical with the Richardson Number). For values Ar>1 stratification can occur. Under the assumption of stratification the code TIRE was developed, which is only applicable for the period of time after some 50 sec after scram. This code serves for long term calculations. As the equations are very simple, it is a very fast code which gives the possibility to calculate transients for some hours real time. This code mainly has to take into account the pressure difference between inner plenum and outlet annulus caused by geodatic pressure. That force is in equilibrium with the pressure drop over the gap and holes in the shield vessel. For more detailed calculations of flow pattern and temperature distribution the code MIX and INKO 2T are applied. MIX was developed and validated at ANL, INKO 2T is a development of INTERATOM. INKO 2T is under validation. Mock up experiments were carried out with water to simulate the transient behavior of the SNR-300 outlet plenum. Calculations obtained by INKO 2T for steady state and the transient are shown for the flow pattern. Results of measurements also prove that stratification begins after about 30 sec. Measurements and detailed calculations show that it is admissible to use the code TIRE for the long term calculations. Calculations for a scram

    There is a growing evidence of an ecological association between alcohol outlet density and intimate partner violence. It is reasonable to assume, however, that not all types of alcohol outlets contribute equally to criminal behavior, and to date, most ecological studies have been of large urban cities. Using Bloomington, Indiana, block groups as units of analysis and controlling for several structural characteristics associated with violence rates, I estimated spatially lagged regression models to determine if the variation in alcohol outlet density, including total outlets and disaggregating by on- and off-premise outlets, is related to intimate partner violence density. Results suggested that total alcohol outlet density and off-premise alcohol outlet density were significantly associated with intimate partner violence density. On-premise alcohol outlet density was not significantly associated with intimate partner violence density. These results not only extend the geographic scope of this relationship beyond large metropolitan areas but also have important policy implications. PMID:26646575

    It is nearly 40 years since Bacillus Calmette-Guérin (BCG) was first used as an immunotherapy to treat superficial bladder cancer. Despite its limitations, to date it has not been surpassed by any other treatment. As a better understanding of its mechanism of action and the clinical response to it have evolved, some of the questions around optimal dosing and treatment protocols have been answered. However, its potential for toxicity and failure to produce the desired clinical effect in a significant cohort of patients presents an ongoing challenge to clinicians and researchers alike. This review summarizes the evidence behind the established mechanism of action of BCG in bladder cancer, highlighting the extensive array of immune molecules that have been implicated in its action. The clinical aspects of BCG are discussed, including its role in reducing recurrence and progression, the optimal treatment regime, toxicity and, in light of new evidence, whether or not there is a superior BCG strain. The problems of toxicity and non-responders to BCG have led to development of new techniques aimed at addressing these pitfalls. The progress made in the laboratory has led to the identification of novel targets for the development of new immunotherapies. This includes the potential augmentation of BCG with various immune factors through to techniques avoiding the use of BCG altogether; for example, using interferon-activated mononuclear cells, BCG cell wall, or BCG cell wall skeleton. The potential role of gene, virus, or photodynamic therapy as an alternative to BCG is also reviewed. Recent interest in the immune check point system has led to the development of monoclonal antibodies against proteins involved in this pathway. Early findings suggest benefit in metastatic disease, although the role in superficial bladder cancer remains unclear. PMID:26000263

Obtained data have been compared with the results of dynamic measurement of kidney sizes in a standard projection. According to the results only at 19,1% of cases statistically significant urodynamic differences have not been revealed in comparison with control group. Diagnostic accuracy of organic form of urodynamic obstructions is 84%, of functional in 64,7% of observations and in 52,9% of cases the infection of urinary tracts with incomplete evacuation of bladder has been diagnosed. The degree of kidney and ureter expansion is not a differential diagnostic criterion of organic or functional urodynamic obstructions. However, using a principle of estimation of upper and lower urinary tracts condition, it is possible to make a prenatal differential diagnosis of variants of defects

  18. Chemoprevention of bladder cancer.

    The data presented herein, although highly supportive for a protective role of various nutrients against bladder cancer, are far from definitive. Many authorities question the validity of current recommendations for nutritional chemoprevention against bladder cancer. The reason for the wide variations reported in epidemiologic studies lies in the nature of observational studies. Dietary studies are limited in their conclusions because the protection afforded by the consumption of a particular nutrient may be multifactorial, with different components of the food exerting potential chemopreventive effects. Furthermore, measuring levels of nutrients in the food intake of populations is confounded by factors that might affect these levels and also the incidence of cancer. For example, vitamin A can come from animal or vegetarian sources. Because animal fat has been identified as a potential carcinogen in man, depending on the source of the vitamin, varying levels of protection might be deduced. In addition, chemoprevention studies using dietary supplements are expected to have mild effects, and large studies would be required to confirm statistical significance. Even with agents such as intravesical chemotherapy, only half the studies achieve statistical significance [29]. Prospective randomized trials with a large sample size, longer follow-up, and an extended duration of treatment are needed to clarify the association between micronutrients and cancer protection. With these caveats in mind, several recommendations can be made. Simple measures, such as drinking more fluids (especially water), can have a profound impact on the incidence of bladder cancer. Vitamins are being extensively studied in chemopreventive trials for different cancers. There is strong evidence for a chemoprotective effect of vitamin A in bladder cancer. The authors recommend 32,000 IU/day of vitamin A initially, with lower doses (24,000 IU) for persons less than 50 kg. Because liver toxicity is a

  20. Calcifications of the bladder in schistosomiasis

    International Nuclear Information System (INIS)

    In schistosomiasis calcification of the urinary bladder are characteristic signs that allow a corresponding diagnosis in endemic regions. Problems concerning differential diagnosis occur only in very rare cases. The calcifications of the bladder can be easily detected by native diagnostics. A late complication in an affected bladder is often a bladder carcinoma. (orig.)

  1. Gallstone obstruction in anastomotic stricture: A very rare case

    Full Text Available Gallstone ileus is a rare but serious complication of cholelithiasis. It is a rare cause of small bowel obstruction but it accounts up to 25% of non-strangulated small bowel obstructions in elderly. Obstruction usually occurs in the terminal ileum. Although the most frequent mechanism of gallstone ileus is migration of the gallstone through a gallbladder-duodenal fistula, there have been cases of bowel obstruction caused by gallstones without any findings of bilio-enteric fistula during the operation. The diagnosis is usually delayed due to nonspecific clinical signs and symptoms. Abdominal computerized tomography (CT scan is the optimal way to diagnose the gallstone ileus. It can identify the site and nature of the obstruction. The optimal surgical approach is a matter of debate. Enterolithotomy is the most performed operation. One stage operation should be performed in selected low risk patients. In this study, we report a 55 years old male patient who underwent surgical intervention due to gallstone ileus. During the operation, we observed that two individual gallstones lead to obstruction in anastomoticstricture which was due to the patient’s prior small bowel resection. Also, no fistula was found during the operation between the gall bladder and the gastrointestinal tract of patient. The gallstones were removed by enterolithotomy. Because there was no gallstone in the allbladder, we did not perform cholecystectomy. J Clin Exp Invest 2015; 6 (1: 72-74

    Full Text Available Background. Except for smoking and certain occupational exposures, the etiology of bladder cancer is largely unknown. Several case reports have described familial aggregation of transitional cell carcinoma of the bladder. Although the majority of patients with bladder cancer do not have family history of transitional cell carcinoma of the urinary tract, the study of familial transitional cell carcinoma may lead to the knowledge on the pathogenesis of this disease. The purpose of this study was to describe three cases of urinary bladder cancer in a single three-member family, i.e. in two generations (mother and son and a family member related by marriage (the patient’s wife. Case report. Three cases of urinary bladder cancer occurred in a three-member family within the interval of 5 years. The following common characteristics were detected in our patients: old age (over 60, working as farmers for more than 50 years, negative personal medical history on relevant health disorders, place of birth - village, place of residence - village, the same water supply, similar nutrition, positive family history on urinary bladder cancer or other malignant tumors, the first sign of illness was macroscopic hematuria in all the patients and the same pathohistological type of cancer - carcinoma papillare transitiocellulare. Conclusion. The stated common characteristics in our cases indicate, above all, the impact of exposure to external surrounding factors on the occurrence of urinary bladder cancer.

    Overactive bladder is one of the most common bladder problems, but an estimated 20 million Americans have underactive bladder (UAB), which makes going to the bathroom difficult, increases the risk of urinary tract infections, and even leads to institutionalization. This article provides an overview of UAB in older adults, and discusses the prevalence, predisposing factors, cause, clinical investigations, and treatments. At present, there is no effective therapy for UAB. A great deal of work still needs to be done on understanding the pathogenesis and the development of effective therapies. PMID:26476113

  8. Teardrop bladder: additional considerations

    International Nuclear Information System (INIS)

    Nine cases of teardrop bladder (TDB) seen at excretory urography are presented. In some of these patients, the iliopsoas muscles were at the upper limit of normal in size, and additional evaluation of the perivesical structures with computed tomography (CT) was necessary. CT demonstrated only hypertrophied muscles with or without perivesical fat. The psoas muscles and pelvic width were measured in 8 patients and compared with the measurements of a control group of males without TDB. Patients with TDB had large iliopsoas muscles and narrow pelves compared with the control group. The psoas muscle width/pelvic width ratio was significantly greater (p < 0.0005) in patients with TDB than in the control group, with values of 1.04 + 0.05 and 0.82 + 0.09, respectively. It is concluded that TDB is not an uncommon normal variant in black males. Both iliopsoas muscle hypertrophy and a narrow pelvis are factors that predispose a patient to TDB

    The patient is an 80-year-old man who presented with gross hematuria. His past medical history indicates he was a cigarette smoker with 50 pack/years. He was successfully treated for carcinoma of the lung 7 years ago. He received chemotherapy, radiation, and surgery. He has mild COPD but has a good performance status. His laboratory studies do not indicate any abnormalities in terms of renal function. He does not have any significant cardiac disease. He has a medium build. He had prostate cancer and underwent a successful radical prostatectomy 10 years ago. His PSA is undetectable. He has some urinary incontinence and wears two pads/day. He underwent the appropriate investigations for gross hematuria. A CT scan of the abdomen and pelvis was normal with the exception of a 4-cm posterior mass in the bladder. There was no hydronephrosis and no enlarged lymph nodes. He underwent a transurethral resection of a solitary bladder tumor performed by another urologist. The tumor was described as large and sessile. It was located on the posterior wall and was approximately 4 cm. The bimanual examination did not reveal a mass. The pathology report stated that the tumor was a high-grade urothelial carcinoma with invasion into the muscularis propria. There was no lymphovascular invasion. I performed a reTURBT, and at that procedure, I did not identify any obvious tumor but the prior resection site was evident. I resected the prior tumor site quite extensively both in depth and width. The pathology revealed only focal carcinoma in situ. There was ample muscle in the specimen and there was some fat as well. As stated, they were free of any cancer. The patient is receptive to any treatment approach. PMID:27457483

    Full Text Available Forty patients with symptoms of neuro-vascular compression in the upper extremities were subjected to impedance plethysmographic study using Parulkar′s method. Two patients recorded decreased blood flow (BFI in supine position and were diagnosed as having partial occlusion at subclavian level. Sixteen of the patients recorded decreased BFI on 90 degrees abduction and hyper-abduction. Twelve of these patients had radiological evidence of anomalous cervicle ribs. In remaining four patients extrinsic impression on the subclavian artery due to fibrous deposits was confirmed by arteriography. Remaining 22 patients recorded normal impedance plethysmograms. Impedance plethysmography thus provided a non-invasive modality for confirmation of vascular compression in thoracic outlet syndrome.

    The Black and Marmara Seas have witnessed increased scientific interest in last decade due to improved cooperation between the riparian countries and western scientific institutions but also due to the controversy existing about the origin of the reconnection of the Black Sea and Mediterranean seas after the last Glacial Maximum and its ensuing sea level rise. The Black Sea is linked to the global ocean only through the Bosphorus-Dardanelles system of straits. The Bosphorus is narrow (0.76 to 3.6 km wide) and shallow (32 m) at the sill, restricting the two-way water exchange between the brackish Black Sea and the very saline Mediterranean Sea. The Bosphorus sill was responsible for the behaviour of the Black Sea during the global glaciations and deglaciations, during which the Black Sea level followed the global sea level changes as long as they were higher than the sill. When global sea level was lower than the Bosphorus sill the variations of the Black Sea level reflected specific regional climate conditions without being coupled to the ocean changes. Recent studies suggest that a rapid flooding event may have occurred in the Black Sea during the Holocene. In 1998, a French-Romanian survey collected 4500 km of high-resolution seismic profiles, multibeam bathymetry, and sediment cores on the northern margin of the Black Sea where the shelf is sufficiently wide to preserve ancient shorelines in the vicinity of the shelf edge. If rapid flooding occurred through the Bosphorus Strait to drown these shorelines, it should have created a cataract. In August 2002, the French research vessel "Le Suroit" equipped with a EM 300 multibeam echosounder and a TritonElics Chirp Sonar mapped the Bosphorus outlet at the shelf edge. The results show a large retrogressive canyon deeply incised into the shelf which can be followed landward towards the Bosphorus outlet. Coring on the shelf and in the canyon revealed mega-ripples of shell debris of recent origin.

    OBJECTIVE To evaluate the use of a percutaneous transabdominal catheter (PTC) for urinary bladder drainage in goats, sheep, and potbellied pigs with obstructive urolithiasis. DESIGN Retrospective case series. ANIMALS 43 goats, 10 sheep, and 16 potbellied pigs (all males) with obstructive urolithiasis evaluated at the University of California-Davis Veterinary Medical Teaching Hospital. PROCEDURES Medical records of goats, sheep, and potbellied pigs examined because of obstructive urolithiasis from January 2000 through December 2014 were reviewed. Records of animals for which a standard PTC had been placed into the urinary bladder as part of disease management were selected. Data were collected regarding signalment, complications associated with PTC placement, and duration of PTC placement prior to removal. RESULTS 42 of 43 goats, 5 of 10 sheep, and all potbellied pigs were castrated. Median (range) duration of PTC placement was 2 (1 to 4) days for goats, 1 (1 to 4) day for sheep, and 1 (1 to 3) day for potbellied pigs. Complications associated with PTC placement included blockage of the catheter by urine sediment, perforation of the cecum, and migration of the catheter out of the urinary bladder. CONCLUSIONS AND CLINICAL RELEVANCE Placement of a PTC into the urinary bladder allowed for effective stabilization of goats, sheep, and potbellied pigs with obstructive urolithiasis while acid-base and electrolyte imbalances were corrected. Use of a PTC should be considered for urinary bladder drainage during medical management or prior to surgical management of obstructive urolithiasis for these species. PMID:27172346

    2008-06-01

    Urinary retention is the inability to empty the bladder completely, and may result from bladder hypocontractility, increases in outlet resistance or both. Chronic urinary retention can lead to several urological complications and is often refractory to pharmacologic, behavioral and surgical treatments. We sought to determine whether electrical stimulation of sensory fibers in the pudendal nerve could engage an augmenting reflex and thereby improve bladder emptying in an animal model of urinary retention. We measured the efficiency of bladder emptying with and without concomitant electrical stimulation of pudendal nerve afferents in urethane-anesthetized rats. Voiding efficiency (VE = voided volume/initial volume) was reduced from 72 ± 7% to 29 ± 7% following unilateral transection of the sensory branch of the pudendal nerve (UST) and from 70 ± 5% to 18 ± 4% following bilateral transection (BST). Unilateral electrical stimulation of the proximal transected sensory pudendal nerve during distention-evoked voiding contractions significantly improved VE. Low-intensity stimulation at frequencies of 1-50 Hz increased VE to 40-51% following UST and to 39-49% following BST, while high-intensity stimulation was ineffective at increasing VE. The increase in VE was mediated by increases in the duration of distention-evoked voiding bladder contractions, rather than increases in contraction amplitude. These results are consistent with an essential role for pudendal sensory feedback in efficient bladder emptying, and raise the possibility that electrical activation of pudendal nerve afferents may provide a new approach to restore efficient bladder emptying in persons with urinary retention.

  8. Bladder preservation using chemoradiation therapy for locally invasive bladder cancer

    International Nuclear Information System (INIS)

    We investigated the long-term results and molecular markers of outcome with selective organ preservation in invasive bladder cancer using chemoradiation therapy. We examined locally invasive bladder cancer in 32 patients (30 men, 2 women; mean age at treatment 68.1 years) who underwent bladder-sparing protocols in the Department of Urology at Sumitomo Hospital between 2000 and 2005. The clinical stage was T2, T3, and T4 in 13, 16, and 3 patients, respectively. Our protocol includes aggressive transurethral resection of the bladder tumor (TURBT) and 46 Gy radiotherapy (2 Gy/fraction, 5 fractions/week) to the pelvis with concurrent cisplatin chemotherapy (20 mg/body/day, 5 days/week, the first and fourth week, intravenously). The initial evaluation included magnetic resonance imaging (MRI), urine cytology, and cystoscopy with a biopsy. During follow-up, if the patients developed superficial recurrence, they was treated with TURBT and intravesical Bacillus Calmette-Guerin (BCG), while patients with invasive recurrence were advised to undergo a salvage cystectomy. We examined the association between the expression of the Bcl-2 family in pretreatment TUR specimens and patient outcome. The mean follow-up was 54.6 months. The first assessment after the induction chemoradiotherapy showed that bladder preservation was achieved in 27 patients (84.4%). The actuarial local control rate with an intact bladder was 56.3% (18 patients) at 3 years. The 1-, 3-, and 5-year cancer-specific survival rate was 90.6, 84.0, and 66.9%, respectively. The 5-year cancer-specific survival rate was 75.0, 67.2, and 33.3% in T2, T3, and T4, respectively. Bcl-x positivity was significantly associated with a poor cancer-specific survival rate (log-rank test, p=0.038). Chemoradiation therapy for invasive bladder cancer can achieve survival rates similar to those in patients treated with radical cystectomy, with successful bladder preservation. Our results suggest that the expression of Bcl-x is a

  9. Imaging of urinary bladder tumors

    International Nuclear Information System (INIS)

    Full text: Primary bladder neoplasms account for 2%-6% of all tumors, with urinary bladder cancer ranked as the fourth most common cancer in males. Transitional cell carcinoma (TCC) is the most common subtype of urothelial tumour accounting for approximately 90% of all urothelial cancers. It is typically observed in men aged 50-70 years with history of smoking or occupational exposure to carcinogens. Most urothelial neoplasms are low-grade papillary tumors, with high incidence of recurrence, requires rigorous follow-up but have a relatively good prognosis. Other bladder neoplasm include squamous cell carcinoma accounts for 2%-15% mainly according to geographic location; adenocarcinoma - less than 2% /both occurring in the context of chronic bladder infection and irritation/; mesenchymal tumors in 5%, with the most common examples being rhabdomyosarcoma in children and leiomyosarcoma in adults. More rare mesenchymal tumors include paraganglioma, lymphoma, leiomyoma and solitary fibrous tumor which have no specific typical imaging findings to be differentiated. Multidetector computed tomography urography is an efficient tool for diagnosis and follow-up in patients with transitional cell carcinoma and it can be considered the primary radiologic method for detection, staging and assessment of the entire urothelium regarding the multicentric nature of TCC. MRI is rapidly expanding modality of choice especially in locally staging the tumor and in controversies. Accurate TNM staging is primordial in choosing treatment and prognosis for patients with bladder carcinoma. Correct interpretation and classification of the tumour is helpful for the urologists to determine further management in these cases. The learning objectives of the presentation are: to illustrate the spectrum of CT and MRI findings and to assess their clinical value in patients with transitional cell carcinoma and some other bladder neoplasm; to discuss the TNM staging based on the imaging findings; to be

    Full Text Available Interest has been increasing in regulating the location and number of tobacco vendors as part of a comprehensive tobacco control program. The objective of this paper is to examine the distribution of tobacco outlets in a large jurisdiction, to assess: (1 whether tobacco outlets are more likely to be located in vulnerable areas; and (2 what proportion of tobacco outlets are located close to schools. Retail locations across the Province of Ontario from Ministry of Health Promotion data were linked to 2006 Census data at the neighbourhood level. There was one tobacco retail outlet for every 1,000 people over age 15 in Ontario. Density of outlets varied by public health unit, and was associated with the number of smokers. Tobacco outlets were more likely to be located in areas that had high neighbourhood deprivation, in both rural and urban areas. Outlets were less likely to be located in areas with high immigrant populations in urban areas, with the reverse being true for rural areas. Overall, 65% of tobacco retailers were located within 500 m of a school. The sale of tobacco products is ubiquitous, however, neighbourhoods with lower socio-economic status are more likely to have easier availability of tobacco products and most retailers are located within walking distance of a school. The results suggest the importance of policies to regulate the location of tobacco retail outlets.

  11. Urinary Obstruction in Prostate Cancer Patients From the Dutch Trial (68 Gy vs. 78 Gy): Relationships With Local Dose, Acute Effects, and Baseline Characteristics

    International Nuclear Information System (INIS)

    Purpose: To investigate the relationship between late urinary obstruction and the details of the dose distribution of irradiated prostate cancer patients, taking into account their baseline symptoms and acute complaints. Patients and Methods: We selected patients from the Dutch multicenter trial randomized between 68 Gy and 78 Gy, for whom toxicity data and dose data were available (n = 557). The absolute dose surface parameters of the delineated bladder were calculated. Next, we constructed three-dimensional dose maps of the area around the prostate, providing an approximate identification of the corresponding anatomic locations. The dose difference maps were constructed by subtracting the mean dose maps of the patients with and without late urinary obstruction. Selected local dose points were analyzed using Cox regression analysis. Results: Urinary obstruction was scored for 40 patients, including 19 of 296 patients who received 68-72 Gy and 21 of 261 patients who received 76-78 Gy. A total of 19 events occurred within 2 years after irradiation and 21 events after 2 years. The bladder surface receiving ≥80 Gy predicted (p <.01) the occurrence of obstruction within 2 years. The dose difference map indicated highly significant differences in the bladder neck situated in the trigonal region (p < .001) that were especially predictive of obstruction after 2 years and of the diagnosis of bladder neck obstruction. Baseline complaints and transurethral resection of the prostate and acute complaints were mainly predictive for obstruction within 2 years. Conclusion: Relatively early events of urinary obstruction were associated with urinary problems existing before RT, acute toxicity, previous transurethral resection of the prostate, and hotspots in the bladder. Events after 2 years were associated with the local dose in the trigonal area.

  12. Coolant mixing in the LMFBR outlet plenum

    International Nuclear Information System (INIS)

    Small scale experiments involving water flows are used to provide mean flow and turbulence field data for LMFBR outlet plenum flows. Measurements are performed at Reynolds Number (Re) values of 33000 and 70000 in a 1/15-scale FFTF geometry and at Re = 35000 in a 3/80-scale CRBR geometry. The experimental behavior is predicted using two different turbulence model computer programs, TEACH-T and VARR-II. It is found that the qualitative nature of the flow field within the plenum depends strongly upon the distribution of the mean inlet velocity field, upon the degree of inlet turbulence, and upon the turbulence momentum exchange model used in the calculations. It is found in the FFTF geometry that the TEACH-T predictions are better than that of VARR-II, and in the CRBR geometry neither code provides a good prediction of the observed behavior. From the sensitivity analysis, it is found that the production and dissipation of turbulence are the dominant terms in the transport equations for turbulent kinetic energy and turbulent energy dissipation rate, and the diffusion terms are relatively small. From the same study a new set of empirical constants for the turbulence model is evolved for the prediction of plenum flows

    Full Text Available Objective: Alcohol is more likely than any other drug to be involved in substance-related violence. In 2000 violence-related and self-directed injuries accounted for an estimated $37 billion and $33 billion in productivity losses and medical treatment, respectively. A review of emergency department data revealed violence and clinically identified trauma-related injuries have the strongest correlation among alcohol-dependent injuries. At the environmental level there is a relationship between alcohol outlet density and violent crime. A limited number of studies have examined the relationship between alcohol outlet type and the components of violent crime. The aim of this study is to examine the relationship between the aggregate components of violent crime and alcohol outlet density by type of outlet.Methods: For this study we used Washington, D.C. census tract data from the 2000 census to examine neighborhood characteristics. Alcohol outlet, violent crime, and population-level data for Washington, D.C. were drawn from various official yet publicly available sources. We developed an analytic database to examine the relationship between alcohol outlet category and four types of violent crime. After estimating spatial correlation and determining spatial dependence, we used a negative binomial regression analysis to assess the alcohol availability-violent crime association, while controlling for structural correlates of violence.Results: Independent of alternative structural correlates of violent crime, including the prevalence of weapons and illicit drugs, community-level alcohol outlet density is significantly associated with assaultive violence. Outlets were significantly related to robbery, assault, and sexual offenses. In addition, the relationship among on-premise and off-premise outlets varied across violent crime categories.Conclusion: In Washington, D.C., alcohol outlet density is significantly associated with the violent crimes.

    The availability of food high in fat, salt and sugar through Fast Food (FF) or takeaway outlets, is implicated in the causal pathway for the obesity epidemic. This review aims to summarise this body of research and highlight areas for future work. Thirty three studies were found that had assessed the geography of these outlets. Fourteen studies showed a positive association between availability of FF outlets and increasing deprivation. Another 13 studies also included overweight or obesity data and showed conflicting results between obesity/overweight and FF outlet availability. There is some evidence that FF availability is associated with lower fruit and vegetable intake. There is potential for land use policies to have an influence on the location of new FF outlets. Further research should incorporate good quality data on FF consumption, weight and physical activity. PMID:20623025

    Alteration of the emptying function of the bladder observed during the natural history of benign prostatic hyperplasia may be related to a biochemical disorder, more specifically a disorder of energy metabolism. Under conditions of obstruction, the bladder is no longer able to contract effectively as it is unable to produce a sufficient quantity of energy. This energy dysfunction is induced by anaerobic diversion of glucose metabolism. The key element of this disturbance is the mitochondrion. Morphological studies have demonstrated degeneration of this organelle controlling energy metabolism. This intracellular alteration is also reflected by functional changes. Disturbances of the various mitochondrial energy producing cycles appear to be responsible for detrusor dysfunction. Further investigations are necessary, especially clinical studies to corroborate these experimental findings. A better knowledge of the pathophysiology of vesical functional consequences of BPH would allow the use of new therapeutic categories of drugs. PMID:12463112

    A randomized controlled prospective evaluation of intravesical and percutaneous bacillus Calmette-Guerin immunotherapy was done in 57 patients with transitional cell carcinoma of the bladder. In addition, 9 patients at high risk for tumor recurrence were treated with bacillus Calmette-Guerin produced a self-limited cystitis and 1 complication (hydronephrosis) of immunotherapy was observed. Of the 57 randomized patients 54 were followed for 3 to 30 months. Tumor recurrence was documented in 13 of 26 controls (50 per cent) and only 6 of 28 patients (21 per cent) treated with bacillus Calmette-Guerin (p equals 0.027, chi-square). The interval free of disease was prolonged significantly with bacillus Calmette-Guerin treatment (p equals 0.014, generalized Wilcoxon test). Importantly, a simple purified protein derivative skin test distinguished those patients who responded to bacillus Calmette-Guerin immunotherapy from those who did not. Only 1 of 17 treated patients (6 per cent) whose purified protein derivative test converted from negative to positive had tumor recurrence compared to 5 recurrences (38 per cent) among the 13 patients whose test remained negative or had been positive before treatment (p equals 0.022, chi-square). Bacillus Calmette-Guerin was given to 10 patients with stage B transitional cell carcinoma who were not candidates for cystectomy and 7 are free of disease. Of 5 patients with carcinoma in situ 3 remain free of tumor after bacillus Calmette-Guerin treatment and 5 of 6 who had multiple recurrences after intravesical chemotherapy responded favorably to bacillus Calmette-Guerin immunotherapy.

  20. OBSTRUCTIVE NEPHROPATHY: ITS PHYSIOPATHOLOGY

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Obstructive nephropathy is the functional and /or parenchymal renal damage secondary to the urinary tract occlusion at any part of it. The inducing urinary obstruction diseases can vary depending on the patient´s age and gender. There are many renal dysfunction inducing mechanisms involved in this entity: increase in the intra-luminal pressure, ureteral dilatation with ineffective ureteral peristalsis, glomerular ultrafiltration net pressure reduction, intra-renal glomerular blood flux reduction due to vasoconstriction, and local disease of chemotactic substances. Obstructive nephropathy can also lead to hypertension (vasoconstriction-hypervolemia, hyperkalemia, metabolic acidosis (aldosterone resistance, diabetes insipidus (vasopressine resistance. In conclusion, since obstructive nephropathy is a potentially reversible cause of renal dysfunction, it should always be taken into account among the differential diagnosis of renal failure inducing mechanisms.

    International Nuclear Information System (INIS)

    Although /sup 133/xenon ventilation studies and aerosol inhalation images have been shown to be more sensitive than other measurements of pulmonary function in detecting early airway disease, they fall short as ideal screening tests. In addition they do not distinguish between the different diseases of air flow obstruction. The diagnosis of the conditions discussed in this paper does not require studies of regional lung function. It is doubtful if further refinements in instrumentation or the introduction of other radioisotopes would really help in this matter. Chronic bronchitis, emphysema, and bronchial asthma are the major obstructive pulmonary disease. Cystic fibrosis and bronchiectasis, which are less common, are also accompanied by airway obstruction. Local obstruction of a bronchus may also occur as a result of a tumor or foreign body or a mucous plug

    We discuss MRI findings in patients with thoracic outlet syndrome (TOS). A total of 100 neurovascular bundles were evaluated in the interscalene triangle (IS), costoclavicular (CC), and retropectoralis minor (RPM) spaces. To exclude neurogenic abnormality, MRIs of the cervical spine and brachial plexus (BPL) were obtained in neutral. To exclude compression on neurovascular bundles, sagittal T1W images were obtained vertical to the longitudinal axis of BPL from spinal cord to the medial part of the humerus, in abduction and neutral. To exclude vascular TOS, MR angiography (MRA) and venography (MRV) of the subclavian artery (SA) and vein (SV) in abduction were obtained. If there is compression on the vessels, MRA and MRV of the subclavian vessels were repeated in neutral. Seventy-one neurovascular bundles were found to be abnormal: 16 arterial-venous-neurogenic, 20 neurogenic, 1 arterial, 15 venous, 8 arterial-venous, 3 arterial-neurogenic, and 8 venous-neurogenic TOS. Overall, neurogenic TOS was noted in 69%, venous TOS in 66%, and arterial TOS in 39%. The neurovascular bundle was most commonly compressed in the CC, mostly secondary to position, and very rarely compressed in the RPM. The cause of TOS was congenital bone variations in 36%, congenital fibromuscular anomalies in 11%, and position in 53%. In 5%, there was unilateral brachial plexitis in addition to compression of the neurovascular bundle. Severe cervical spondylosis was noted in 14%, contributing to TOS symptoms. For evaluation of patients with TOS, visualization of the brachial plexus and cervical spine and dynamic evaluation of neurovascular bundles in the cervicothoracobrachial region are mandatory.

    Full Text Available BACKGROUND: Infravesical obstruction leads to kidney and bladder dysfunction in a significant proportion of boys. The aim of this review is to determine the value of diagnostic tests for ascertainment of infravesical obstruction in boys. METHODOLOGY: We searched PubMed and EMBASE databases until January 1, 2013, to identify papers that described original diagnostic accuracy research for infravesical obstruction in boys. We extracted information on (1 patient characteristics and clinical presentation of PUV and (2 diagnostic pathway, (3 diagnostic accuracy measures and (4 assessed risk of bias. PRINCIPAL FINDINGS: We retrieved 15 studies describing various diagnostic pathways in 1,189 boys suspected for infravesical obstruction. The included studies reflect a broad clinical spectrum of patients, but all failed to present a standardised approach to confirm the presence and severity of obstruction. The risk of bias of included studies is rather high due to work-up bias and missing data. CONCLUSIONS: As a consequence of low quality of methods of the available studies we put little confidence in the reported estimates for the diagnostic accuracy of US, VCUG and new additional tests for ruling in or ruling out infravesical obstruction. To date, firm evidence to support common diagnostic pathways is lacking. Hence, we are unable to draw conclusions on diagnostic accuracy of tests for infravesical obstruction. In order to be able to standardise the diagnostic pathway for infravesical obstruction, adequate design and transparent reporting is mandatory.

    We present the case of an infant who suffered intraperitoneal bladder perforation secondary to routine neonatal circumcision with the Plastibell device. On day-of-life 5, the patient presented with abdominal distention, vomiting, diarrhea, and severe acute renal failure. After removal of a distal meatal obstruction caused by the Plastibell device and open repair of the bladder defect, the patient had an uneventful recovery with rapid return of renal function. Despite the relative safety of the Plastibell, this case underscores the importance of careful device placement, parental education, keen clinical judgment, and prompt intervention when indicated.

    A case-control study of 149 intentionally self-inflicted gun injury cases (including completed gun suicides) and 302 population-based controls was conducted from 2003 to 2006 in a major US city. Two focal independent variables, acute alcohol consumption and alcohol outlet availability, were measured. Conditional logistic regression was adjusted for confounding variables. Gun suicide risk to individuals in areas of high alcohol outlet availability was less than the gun suicide risk they incurred from acute alcohol consumption, especially to excess. This corroborates prior work but also uncovers new information about the relationships between acute alcohol consumption, alcohol outlets, and gun suicide. Study limitations and implications are discussed. PMID:21929327

  10. PIV measurement at the blowdown pipe outlet

    International Nuclear Information System (INIS)

    This report summarizes the findings of the PIV measurement tests carried out in January - February 2013 with the scaled down PPOOLEX test facility at LUT. The main objective of the tests was to find out the operational limits of the PIV system regarding suitable test conditions and correct values of different adjustable PIV parameters. An additional objective was to gather CFD grade data for verification/validation of numerical models. Both water and steam injection tests were carried out. PIV measurements with cold water injection succeeded well. Raw images were of high quality, averaging over the whole measurement period could be done and flow fields close to the blowdown pipe outlet could be determined. In the warm water injection cases the obtained averaged velocity field images were harder to interpret, especially if the blowdown pipe was also filled with warm water in the beginning of the measurement period. The absolute values of the velocity vectors seemed to be smaller than in the cold water injection cases. With very small steam flow rates the steam/water interface was inside the blowdown pipe and quite stable in nature. The raw images were of good quality but due to some fluctuation in the velocity field averaging of the velocity images over the whole measured period couldn't be done. Condensation of steam in the vicinity of the pipe exit probably caused these fluctuations. A constant outflow was usually followed by a constant inflow towards the pipe exit. Vector field images corresponding to a certain phase of the test could be extracted and averaged but this would require a very careful analysis so that the images could be correctly categorized. With higher steam flow rates rapid condensation of large steam bubbles created small gas bubbles which were in front of the measurement area of the PIV system. They disturbed the measurements by reflecting laser light like seeding particles and therefore the raw images were of poor quality and they couldn't be

    A 6-yr-old male red kangaroo (Macropus rufus) presented for a history of inappetance, abnormal behavior, and unconfirmed elimination for 6 hr prior to presentation. Based on abdominal ultrasound, abdominocentesis, and cystocentesis, a presumptive diagnosis of urinary tract obstruction with uroabdomen and hydronephrosis was reached. Abdominal radiographs did not assist in reaching an antemortem diagnosis. Postmortem examination confirmed a urinary bladder rupture secondary to urethral obstruction by a single urethrolith. Bilateral hydronephrosis and hydroureter were identified and determined to be a result of bilateral ureteroliths. Urolith analysis revealed a composition of 100% calcium carbonate. A dietary analysis was performed, implicating an increased Ca:P ratio from a food preparation miscommunication as a contributing factor. Appropriate husbandry changes were made, and mob surveillance procedures were performed, which resolved the urolithiasis risk for the remaining five animals. PMID:23505728

The case of a 69 years old male patient who attended consultation because of nocturia, thin urine stream, pushing, urgent urination and sense of incomplete emptying is presented. Through rectal examination grade I prostate with discrete grade I asymmetry consistent with right nodular lobe that did not rise to the surface was detected. During the physical examination tumor mass was palpated in the lower abdomen region. It was painless. Ultrasound and cystography showed giant bladder diverticulum with a narrow neck into the right lateral wall of the bladder. Cystoscopy confirmed the diagnosis and the patient was treated trough surgery. Histology revealed mucosal layers and muscle and adventitia in the wall, thus confirming congenital origin. Recovering after surgery was satisfactor.Los divertículos congénitos en el adulto se detectan normalmente asociados a factores obstructivos a la salida vesical, se manifiestan mayormente por sepsis urinarias.

    Bladder cancer is a common urologic malignancy with rising incidence in the elderly population. In most cases, bladder cancer is non-muscle-invasive at diagnosis and shows dramatically high recurrence rates, although current treatments often reduce the risk of disease progression. Immunotherapy using intravesical instillation of Bacillus Calmette-Guérin (BCG) remains the most effective therapy for patients with high risk tumors. However, BCG-therapy has important limitations including substantial adverse events and frequent treatment failure. Thus, it appears crucial to either improve or replace current therapy using new immunotherapeutic strategies. Here, we discuss the clinical trials that assessed therapeutic vaccination of bladder cancer patients using tumor associated antigens and we also argue for novel approaches arising from murine models. Vaccination routes to induce appropriate T-cell homing in the tumor site as well as the use of local immunostimulation to enhance recruitment of vaccine-induced T cells are discussed to highlight what we believe is a promising therapeutic vaccination strategy for patients with non-muscle-invasive bladder cancer.

    Bladder cancer shows rare variants and special subtypes with diverse prognostic importance and therefore may necessitate different therapeutic approaches. For pathologists it is important to histologically diagnose and specify such variants. Nested variants of urothelial carcinoma with inconspicuous, well-formed tumor cell nests present with an aggressive course. The plasmacytoid variant, which morphologically resembles plasma cells is associated with a shorter survival time and a high frequency of peritoneal metastasis. Micropapillary urothelial carcinoma with small papillary tumor cell islands within artificial tissue retraction spaces and frequent lymphovascular invasion also has a poor prognosis. Other important rare differential variants listed in the World Health Organization (WHO) classification are microcystic, lymphoepithelioma-like, sarcomatoid, giant cell and undifferentiated urothelial carcinomas. Additionally, there are three special types of bladder cancer: squamous cell carcinoma, adenocarcinoma and small cell neuroendocrine carcinoma of the bladder. These tumors are characterized by pure squamous cell or glandular differentiation and are sometimes less responsive to adjuvant (chemo)therapy. Small cell carcinoma of the bladder mimics the neuroendocrine features of its pulmonary counterpart, shows an aggressive course but is sensitive to (neo-)adjuvant chemotherapy. The morphology and histology of the most important variants and special types are discussed in this review. PMID:26782034

    The purposes of inlet and outlet devices for rotary blood pumps, including inducers and diffusers for axial pumps, inlet and exit volutes for centrifugal pumps, and inlet and outlet cannulas, are to guide the blood into the impeller, where the blood is accelerated, and to convert the high kinetic energy into pressure after the impeller discharge, respectively. The designs of the inlet and outlet devices have an important bearing on the pump performance. Their designs are highly dependent on computational fluid dynamics (CFD) analysis, guided by intuition and experience. For inlet devices, the design objectives are to eliminate separated flow, to minimize recirculation, and to equalize the radial components of velocity. For outlet devices, the design goals are to reduce speed, to minimize energy loss, and to avoid flow separation and whirl. CFD analyses indicate the velocity field and pressure distribution. Geometrical optimization of these components has been implemented in order to improve the flow pattern. PMID:15384997

    Chronic obstructive pulmonary disease (COPD) is a common disease with high global morbidity and mortality. COPD is characterized by poorly reversible airway obstruction, which is confirmed by spirometry, and includes obstruction of the small airways (chronic obstructive bronchiolitis) and emphysema, which lead to air trapping and shortness of breath in response to physical exertion. The most common risk factor for the development of COPD is cigarette smoking, but other environmental factors, such as exposure to indoor air pollutants - especially in developing countries - might influence COPD risk. Not all smokers develop COPD and the reasons for disease susceptibility in these individuals have not been fully elucidated. Although the mechanisms underlying COPD remain poorly understood, the disease is associated with chronic inflammation that is usually corticosteroid resistant. In addition, COPD involves accelerated ageing of the lungs and an abnormal repair mechanism that might be driven by oxidative stress. Acute exacerbations, which are mainly triggered by viral or bacterial infections, are important as they are linked to a poor prognosis. The mainstay of the management of stable disease is the use of inhaled long-acting bronchodilators, whereas corticosteroids are beneficial primarily in patients who have coexisting features of asthma, such as eosinophilic inflammation and more reversibility of airway obstruction. Apart from smoking cessation, no treatments reduce disease progression. More research is needed to better understand disease mechanisms and to develop new treatments that reduce disease activity and progression. PMID:27189863

    A case–control study of 149 intentionally self-inflicted gun injury cases (including completed gun suicides) and 302 population-based controls was conducted from 2003 to 2006 in a major US city. Two focal independent variables, acute alcohol consumption and alcohol outlet availability, were measured. Conditional logistic regression was adjusted for confounding variables. Gun suicide risk to individuals in areas of high alcohol outlet availability was less than the gun suicide risk they incurr...

    When grains flow out of a silo, the flow rate increases with the outlet size d. If d is too small, an arch may form and blocks the flow at the outlet. To recover from clogging, the arch have to be destroyed. Oscillating the outlet mechanically is one simple way of destroying the arch. In this paper, we report the effect of oscillating the outlet on the processes of clogging as well as recovery from clogging in two-dimensional silo equipped with movable outlet. We measure the flow rate Q (d) and find that, in the presence of outlet oscillation, Q (d) may remain finite even when d is only slightly larger than the grain diameter. Transition from continuous flow to intermittent flow occurs by decreasing d or by reducing the oscillation speed. In addition, at small d when the flow is intermittent, the flow time (duration of flow before clogged) follows Poisson distribution whereas the recovery time (duration of clog before flow recovery) follows power law distribution.

    Full Text Available Background/Aim: Decompression of malignant gastrointestinal obstructions is an uncommon indication for percutaneous endoscopic gastrostomy (PEG tubes. The purpose of this study is to determine the efficacy of venting PEG tubes in relieving nausea and vomiting and assessing complications associated with tube placement. Patients and Methods: This study is a retrospective chart review of patients with PEG tubes placed to decompress malignant gastrointestinal obstructions between January 2005 and September 2010 by the gastroenterology service at our institute. Patient demographics, symptom relief, procedural complications, diet tolerability and home palliation were reviewed. Results: Seven PEG tubes were inserted to decompress malignant gastrointestinal obstructions. The mean patient age was 62 years (range 37-82 years. The underlying primary malignancies were small intestine (1, appendiceal (1, pancreatic (2, and colon (3 cancer. Gastric outlet obstruction was present in 3 (43% patients while small bowel obstruction occurred in 4 (57% patients. There was relief of nausea and vomiting in 6 (86% patients. Procedural complications were present in 1 (14% patient and involved superficial cellulitis followed by peristomal leakage. Patients with gastric outlet obstruction continued to have limited oral intake while patients with small bowel obstruction tolerated varying degrees of oral nutrition. Six (86% patients were discharged home after PEG tube placement, but only 2 (33% were able to undergo end-stage palliation at home without re-admission for hospital palliation. Conclusions: Venting PEG tubes significantly reduce the symptoms of nausea and vomiting in patients with metastatic gastrointestinal obstruction due to primary gastrointestinal malignancies. Complications associated with tube placement were minimal.

  6. Role of renal arterial resistive index (RI) in obstructive uropathy

    International Nuclear Information System (INIS)

    Objective: To determine the diagnostic accuracy of renal arterial resistive index on doppler ultrasound in patients with acute renal colic to diagnose obstructive uropathy taking non-enhanced helical computed tomography as the gold standard. Methods: The descriptive study, conducted at the Radiology Department of Pakistan Naval Ship Shifa Hospital, Karachi, from October 10, 2010 to July 17, 2011, comprised 160 patients referred from the Emergency Department with complaint of unilateral renal colic. Ultrasound was carried out. Subsequently, computed tomography scan of kidney, ureter and bladder was performed. Data was collected on prescribed proforma and analysed using SPSS 19. Results: By taking the resistive index value of > 0.70 as a discriminatory level for obstruction, the overall sensitivity of the index was 76.23% and specificity was 88.13%. The positive predictive values of the index in patients with obstructive uropathy was 91.6%, and negative predictive value was calculated to be 68.42%. The diagnostic accuracy of the test was 80%. Conclusion: Duplex Doppler ultrasound can detect acute renal obstruction with sensitivity of approximately 77%. However, ultrasound is an operator-dependent examination, and the results are much affected by patient body habitus. (author)

    Full Text Available Voiding cystourethrography (VCUG is a commonly performed diagnostic procedure for the evaluation of vesicoureteral reflux with urinary tract infection or congenital renal diseases in children. The procedure is relatively simple and cost-effective, and complications are very rare. The iatrogenic complication of VCUG range from discomfort, urinary tract infection to bacteremia, as well as bladder rupture. Bladder rupture is a rare complication of VCUG, and only a few cases were reported. Bladder rupture among healthy children during VCUG is an especially uncommon event. Bladder rupture associated with VCUG is usually more common in chronically unused bladders like chronic renal failure. Presented is a case of bladder rupture that occurred during a VCUG in a healthy 9-monthold infant, due to instilled action of dye by high pressure. This injury completely healed after 7 days of operation, and it was confirmed with a postoperative cystography. The patient’s bladder volume, underlying disease, velocity of the contrast media instilled, catheter size, and styles of instillation are important factors to prevent bladder rupture during VCUG. Management of bladder rupture should be individualized, but the majority of infants are treated with the operation. In conclusion, bladder rupture is a rare complication, however, delicate attention is needed in order to prevent more dire situations.

    Full Text Available Background. Multiple myeloma is a plasmaproliferative disease characterized by the uncontrolled proliferation of a pathogenic plasma cell clone engaged in the production of monoclonal immunoglobulin. This condition affects the bone marrow, but it can be manifested in any other organ or tissue. The urinary bladder involvement is extremely rare. Case report. We reported a 70-year-old male with the history of multiple myeloma, receiving chemotherapy containing melphalan and prednisone (MP. Two years after the treatment, there was a renal failure associated with oligoanuria, hematuria and bilateral hydronephrosis. The urine cytology tests revealed the atypical cells, so was suspected obstructive uropathy to be caused by urothelium cancer. However, only upon the cystoscopy and biopsy performed on the urinary bladder mass, plasmacytoid infiltration diagnosis was confirmed. This extremely rare variant was presented throughout the illness period and proved to be resistant to the administered chemotherapy. Conclusion. When renal failure associated with hematuria and bilateral hydronephrosis is presented in a patient with multiple myeloma, this unusual and rare extramedular localization should be also considered.

    Full Text Available Abstract Background Interstital cystitis is often treated with exogenous glycosaminoglycans such as heparin, chondroitin sulphate (Uracyst, hyaluronate (Cystistat or the semi-synthetic pentosan polysulphate (Elmiron. The mechanism of action is presumed to be due to a coating of the bladder surface to replace the normally present chondroitin sulphate and heparan sulphate lost as a result of the disease. This study used fluorescent labelled chondroitin sulphate to track the distribution of glycosaminoglycans administered intravesically to mouse bladder that had been damaged on the surface. Methods The surfaces of mouse bladders were damaged by 3 mechanisms – trypsin, 10 mM HCl, and protamine sulphate. Texas Red-labeled chondroitin sulphate was instilled into the bladders of animals with damaged bladders and controls instilled only with saline. Bladders were harvested, frozen, and sectioned for examination by fluorescence. Results The normal mouse bladder bound a very thin layer of the labelled chondroitin sulphate on the luminal surface. Trypsin- and HCl-damaged bladders bound the labelled chondroitin sulphate extensively on the surface with little penetration into the bladder muscle. Protamine produced less overt damage, and much less labelling was seen, presumably due to loss of the label as it complexed with the protamine intercalated into the bladder surface. Conclusion Glycosaminoglycan administered intravesically does bind to damaged bladder. Given that the changes seen following bladder damage resemble those seen naturally in interstitial cystitis, the mechanisms proposed for the action of these agents is consistent with a coating of damaged bladder.

    Full Text Available In this paper we describe the causes, patterns of presentation, and management of obstructive uropathy in Sudanese patients in a retrospective multi-center audit. All patients who presented with obstructive uropathy during 2005 were included in this study. All of the patients were subjected to serial investigations including imaging and tests of renal function. Diversion, stenting, and/or definitive surgery were performed in order to relieve the obstruction. Five hundred twenty patients were diagnosed with obstructive uropathy during this period; 345 (66% patients presented with chronic obstruction and 175 (34% with acute obstruction. Of the study patients, 210 (40% presented with significant renal impairment; 50 (23% of them required emergent dialysis. The patterns of clinical presentation of the obstructed patients included pain at the site of obstruction in 48%, lower urinary tract symptoms in 42%, urine retention in 36.5%, mass effect in 22%, and anuria in 4%. Patients in the pediatric age group constituted 4% of the total. The common causative factors of obstruction included congenital urethral valves, pelvi-ureteral junction obstruction, urolithiasis, and iatrogenic trauma, especially in the obstetric practice. Renal function was completely recovered with early management in 100% of patients with acute obstruction and was stabilized in 90% of patients with chronic obstruction. Four patients were diagnosed with end-stage renal failure; two of them were transplanted. The mortality rate in this study was less than 0.3%.

    Full Text Available OBJECTIVES: The current study set out to investigate alcohol availability in a densely populated, residential area of suburban São Paulo associated with high levels of social deprivation and violence. Gun-related deaths and a heavy concentration of alcohol outlets are notable features of the area surveyed. Given the strong evidence for a link between alcohol availability and a number of alcohol-related problems, including violent crime, measures designed to reduce accessibility have become a favored choice for alcohol prevention programs in recent years. METHODS: The interviewers were 24 residents of the area who were trained for the study. It was selected an area of nineteen streets, covering a total distance of 3.7 km. A profile of each alcohol outlet available on the area was recorded. RESULTS: One hundred and seven alcohol outlets were recorded. The number of other properties in the same area was counted at 1,202. Two measures of outlet density may thus be calculated: the number of outlets per kilometer of roadway (29 outlets/km; and the proportion of all properties that sold alcohol (1 in 12. CONCLUSIONS: The results of this study is compared with others which are mainly from developed countries and shown that the area studied have the highest density of alcohol outlet density ever recorded in the medical literature. The implication of this data related to the violence of the region is discussed. By generating a profile of alcohol sales and selling points, it was hoped to gain a better understanding of alcohol access issues within the sample area. Future alcohol prevention policy would be well served by such knowledge.

    PURPOSE. Assessing food environments often requires using commercially available data. Disparate methods used for classifying food outlets in these databases call for creating a classification approach using common definitions. A systematic strategy for reclassifying food stores and restaurants, as they appear in commercial databases, into categories that differentiate the availability of healthy options is described here. DESIGN AND SETTING. Commercially available data on food outlets including names, addresses, North American Industry Classification System codes, and associated characteristics was obtained for five New Jersey communities. ANALYSIS. A reclassification methodology was developed using criteria and definitions from the literature to categorize food outlets based on availability of healthy options. Information in the database was supplemented by systematic Internet and key word searches, and from phone calls to food outlets. RESULTS. The methodology resulted in 622 supermarket/grocery stores, 183 convenience stores, and 148 specialty stores in the original data to be reclassified into 58 supermarkets, 30 grocery stores, 692 convenience stores, and 115 specialty stores. Outlets from the original list of 1485 full-service restaurants and 506 limited-service restaurants were reclassified as 563 full-service restaurants and 1247 limited-service restaurants. Reclassification resulted in less than one-seventh the number of supermarkets and grocery stores, more than three times the number of convenience stores, and twice as many limited-service restaurants-a much less healthy profile than the one generated by using exclusively the commercial databases. CONCLUSION. An explicit and replicable strategy is proposed for reclassifying food outlets in commercial databases into categories that differentiate on the basis of healthy food availability. The intent is to contribute towards building a consensus among researchers on definitions used in public health

    2014-04-01

    Full Text Available Aim: The aim of this study was to evaluate the simple tube cystostomy procedure for management of urethral obstruction cases in ruminants. Materials and Methods: Tube cystostomy was used to treat a total of 58 ruminants, which included 35 buffalo calves and 23 goats. Diagnosis of the disease was made with the history of anuria, clinical signs, and physical examinations. Physical parameters like heart rate, respiratory rate, rectal temperature dehydration status of animals by skin tenting test, and intraoperative findings were compared. Results: Young ruminants were most commonly affected and the mean age was 4-5 months in both species. Only male were considered for the study in which buffalo calves were not castrated but in goat's 73.91% animal were castrated and 34.7% not castrated. Rupture of bladder was more common in buffalo calves as compared to goats. The confirmed cases of obstructive urolithiasis were selected for tube cystostomy with Foley's catheter. Postoperatively all cases were administered with broad spectrum antibiotic, anti-inflammatory agent, and caliculolytic agents like ammonium chloride. Postoperative complications recorded only in 10 animals and remaining 48 animals had an uneventful recovery. Conclusion: Tube cystostomy is a simple and effective procedure particularly in intact urinary bladder, which can be adopted at field level.

  16. Analysis of intravesical recurrence after bladder-preserving therapy for muscle-invasive bladder cancer

    International Nuclear Information System (INIS)

    The aim of the present study was to analyze the pattern of recurrences after bladder-preserving therapy for muscle-invasive bladder cancer. The subjects were 77 patients with T2-3N0M0 bladder cancer whose bladder was preserved by intra-arterial chemotherapy and radiation. The patterns of the first recurrences were retrospectively analyzed. With a median follow-up of 38.5 months, 17 patients (22.1%) experienced intravesical recurrence without metastasis, 14 (82.4%) of which were cases of non-muscle-invasive bladder cancer recurrence and 3 (17.6%) of which were muscle-invasive bladder cancer recurrences. Muscle-invasive bladder cancer recurred at the same site as the initial tumor site in all three cases, whereas non-muscle-invasive bladder cancer recurred at different sites in 64% of the patients in that group. The peak hazard of the non-muscle-invasive bladder cancer recurrence was observed at around a year after treatment. Recurrent non-muscle-invasive bladder cancer was of a significantly lower histological grade with lower Ki-67-labeling indices than the initial muscle-invasive bladder cancer. Twelve (85.7%) of 14 patients with non-muscle-invasive bladder cancer recurrence achieved disease-free status. The multivariate analysis revealed that multiplicity, grade and tumor size were significantly correlated with the recurrence (P=0.0001, 0.0442 and 0.0412, respectively). Most of the recurrences after bladder-preserving therapy were cases of non-muscle-invasive bladder cancer. The recurrence pattern and characteristics of the tumors did not differ from those of primary non-muscle-invasive bladder cancer. Patients with high-risk factors would be candidates for prophylactic intravesical therapy for non-muscle-invasive bladder cancer recurrence. (author)

  17. Calcium transport in turtle bladder

    International Nuclear Information System (INIS)

    Unidirectional 45Ca fluxes were measured in the turtle bladder under open-circuit and short-circuit conditions. In the open-circuited state net calcium flux (JnetCa) was secretory (serosa to mucosa). Ouabain reversed JnetCa to an absorptive flux. Amiloride reduced both fluxes such that JnetCa was not significantly different from zero. Removal of mucosal sodium caused net calcium absorption; removal of serosal sodium caused calcium secretion. When bladders were short circuited, JnetCa decreased to approximately one-third of control value but remained secretory. When ouabain was added under short-circuit conditions, JnetCa was similar in magnitude and direction to ouabain under open-circuited conditions (i.e., absorptive). Tissue 45Ca content was ≅30-fold lower when the isotope was placed in the mucosal bath, suggesting that the apical membrane is the resistance barrier to calcium transport. The results obtained in this study are best explained by postulating a Ca2+-ATPase on the serosa of the turtle bladder epithelium and a sodium-calcium antiporter on the mucosa. In this model, the energy for calcium movement would be supplied, in large part, by the Na+-K+-ATPase. By increasing cell sodium, ouabain would decrease the activity of the mucosal sodium-calcium exchanger (or reverse it), uncovering active calcium transport across the serosa

    It is biologically plausible for dietary factors to influence bladder cancer risk considering that beneficial as well as harmful components of a diet are excreted through the urinary tract and in direct contact with the epithelium of the bladder. However, studies that investigated the association between dietary factors and bladder cancer (BC) risk have largely reported inconsistent results. The macronutrient intake and risk of BC could have yield inconsistent results across studies because o...

    2013-01-01

    Overactive bladder (OAB) is found in 20% of patients with various disorders of urination, and the imperative urinary incontinence diagnosed in one third of these patients. The study was aimed to improvement the treatment outcomes in OAB women with imperative incontinence and obstructive urination disorders by using a combination of alpha1-adrenoblockers and PDE-5 inhibitors, and to evaluation of relationship between clinical and urodynamic manifestations of the disease. The state of the microcirculation of the bladder mucosa before and after treatment was also evaluated. We have examined and treated 40 women aged 17 to 69 years with disease duration ranged from 1 to 20 years. Patients received combination of al-adrenoblocker alfuzosin (dalfaz) 5 mg at night and reversible selective PDE5 inhibitor tadalafil (Cialis) 5 mg daily in the morning for a month. After treatment, according to the uroflowmetry and cystometry data, the time of urination was reduced, urinary volume and maximum urinary flow rate, as well as cystometric capacity have increased; involuntary detrusor contractions in the bladder filling phase (spontaneous or provoked) became less, or absent. According to the results of ultrasound examination, residual urine volume has decreased. Laser Doppler flowmetry showed an increase of neurogenic tone in precapillary, bypass coefficient and microcirculation effectiveness index, increase in microcirculation index and the coefficient of variation, indicating an improvement of microcirculation in the bladder mucosa. As a result of treatment, the clinical effect was seen in 29 (73%) patients, urinary incontinence was noted only in 6 (15%) patients. PMID:23662495

    Full Text Available Small Cell Carcinoma of the bladder accounts for less than 1% of all bladder tumors. Small Cell Carcinoma of the bladder has an aggressive behaviour and is usually metastatic at diagnosis. Due to its infrequent occurence, the literature on this entity is limited; which unsurprisingly leads to an uncertanity in defining an ideal therapeutic approach. This report, overviews the literature while describing a 70- year- old female patient who is diagnosed with small cell carcinoma of the bladder arising in an unusual localization.

  4. Model for kidney-bladder excretion

    International Nuclear Information System (INIS)

    In order to calculate the effective dose, an explicit tissue weighting factor of 0.05 is given for the bladder. Consequently a model for kidney-bladder excretion is needed to calculate the additional equivalent dose to bladder wall from activity in urine. The mathematical expressions of the model were proposed in ICRP Pub. 53. However, the expressions can only be applied to the materials excreted directly through urine from body fluids. If the intakes were transferred among the tissues or organs of body successively and excreted in urine, the available expressions calculating disintegration of the intakes in urinary path and bladder contents were derived in this paper

  5. Melting beneath Greenland outlet glaciers and ice streams

    Alexander, David; Perrette, Mahé; Beckmann, Johanna

    2015-04-01

    Basal melting of fast-flowing Greenland outlet glaciers and ice streams due to frictional heating at the ice-bed interface contributes significantly to total glacier mass balance and subglacial meltwater flux, yet modelling this basal melt process in Greenland has received minimal research attention. A one-dimensional dynamic ice-flow model is calibrated to the present day longitudinal profiles of 10 major Greenland outlet glaciers and ice streams (including the Jakobshavn Isbrae, Petermann Glacier and Helheim Glacier) and is validated against published ice flow and surface elevation measurements. Along each longitudinal profile, basal melt is calculated as a function of ice flow velocity and basal shear stress. The basal shear stress is dependent on the effective pressure (difference between ice overburden pressure and water pressure), basal roughness and a sliding parametrization. Model output indicates that where outlet glaciers and ice streams terminate into the ocean with either a small floating ice tongue or no floating tongue whatsoever, the proportion of basal melt to total melt (surface, basal and submarine melt) is 5-10% (e.g. Jakobshavn Isbrae; Daugaard-Jensen Glacier). This proportion is, however, negligible where larger ice tongues lose mass mostly by submarine melt (~1%; e.g. Nioghalvfjerdsfjorden Glacier). Modelled basal melt is highest immediately upvalley of the grounding line, with contributions typically up to 20-40% of the total melt for slippery beds and up to 30-70% for resistant beds. Additionally, modelled grounding line and calving front migration inland for all outlet glaciers and ice streams of hundreds of metres to several kilometres occurs. Including basal melt due to frictional heating in outlet glacier and ice stream models is important for more accurately modelling mass balance and subglacial meltwater flux, and therefore, more accurately modelling outlet glacier and ice stream dynamics and responses to future climate change.

    Two patients are described who developed a thoracic outlet syndrome (TOS) after undergoing Ravitch's operation for the correction of pectus excavatum. In one case the syndrome developed a few days after surgery, whereas in the second patient it manifested more gradually. A third patient presented with latent TOS and pectus excavatum. It is recommended that prior to the correction of pectus excavatum, the patient should be examined to detect signs of neurovascular compression due to latent thoracic outlet syndrome. After surgery the possibility of this complication should be kept in mind to avoid permanent lesions of the cervicobrachial plexus. PMID:3352940

    International Nuclear Information System (INIS)

    This paper reports on three usages in the area of construction materials which offer a potential outlet for the reuse of spent fluid catalytic cracking (FCC) catalyst that far exceeds the supply from European refineries. The proximity of the spent catalyst source to the point-of-use is critical because this determines the transportation cost-the major element in the cost of disposal/reuse. This is why a balance geographical spread of reuse outlets throughout Europe is sought. Asphalt, cement, and red bricks containing spent fluid catalytic cracking catalyst, have all passed environmental acceptability tests

    We present an experimental study of the effect that an obstacle above the outlet of a silo has on the clogging probability. Both, the size of the ori ce and the obstacle position are varied for a chosen obstacle size and shape. If the position of the obstacle is properly selected the clogging probability can be importantly reduced. Indeed, as the outlet size is increased – and we approach the critical size above which there is not clogging – the obstacle effect is enhanced. For the ...

    Spheroidal bladder substitutes made from double-folded ileal segments, similar to Goodwin's cup-patch technique, are devoid of major coordinated wall contractions. This, together with the reservoir's direct anastomosis to the membranous urethra, prevents major intraluminal pressure peaks and assures a residue-free voiding of sterile urine. In order to determine whether, under these conditions, an afferent tubular isoperistaltic ileal segment of 20-cm length protects the upper urinary tract as efficiently as an antireflux nipple, 60 male patients who were subjected to radical cystectomy were prospectively randomised to groups in which a bladder substitute was formed together with either of these 2 antireflux devices. An analysis of the results obtained in 20 patients from each group who could be followed for more than 1 year (median observation time 30 and 36 months) showed no differences between the groups in metabolic disturbances, kidney size, reservoir capacity, diurnal and nocturnal urinary continence, the incidence of urinary tract infection or episodes of acute pyelonephritis. Later than 1 year postoperatively, intravenous urograms of the renoureteral units of 25% of the patients with antireflux nipples showed persistent but generally slight dilatation of the upper urinary tracts. This observation was significantly more frequent than it was in patients with afferent tubular segments. Urodynamic and radiographic studies showed that the competence of the antireflux nipples was secured by the raised surrounding intravesical pressure. This, however, also resulted in a transient functional obstruction, and a gradual rise of the basal pressure in the upper urinary tracts was recorded. In patients with afferent ileal tubular segments, contrast medium could be forced upwards into the renal pelvis when the bladder substitutes were overfilled. However, despite raised intravesical pressures, peristalsis in the isoperistaltic afferent tubular segment gradually returned

    Pancreatic cancer and cholangiocarcinoma are the most common causes of malignant biliary obstruction. They are diseases of increasing incidence and unfavorable prognosis. Only patients with localized disease indicated for surgery have a chance of long-term survival. These patients represent less than 20 % of all patients, despite the progress in our diagnostic abilities.Locally advanced and metastatic tumors are treated with palliative chemotherapy or chemoradiotherapy; the results of such treatments are unsatisfactory. The average survival of patients with unresectable disease is 6 months and only 5-10 % of patients survive 5 years.Biliary drainage is an integral part of palliative treatment. Endoscopically or percutaneosly placed stents improve quality of life, decrease cholestasis and pruritus, but do not significantly improve survival. Biliary stents get occluded over time, possibly resulting in acute cholangitis and require repeated replacement.Photodynamic therapy and radiofrequency ablation, locally active endoscopic methods, have been increasingly used in recent years in palliative treatment of patients with malignant biliary obstruction. In photodynamic therapy, photosensitizer accumulates in tumor tissue and is activated 48 hours later by light of a specific wave length. Application of low voltage high frequency current during radiofrequency ablation results in tissue destruction by heat. Local ablation techniques can have a significant impact in a large group of patients with malignant biliary obstruction, leading to improved prognosis, quality of life and stent patency.

  15. Duplicated gall bladder detected on 99m Tc HIDA hepatobiliary scintigraphy: A report of two cases

    International Nuclear Information System (INIS)

    Gall bladder (GB) duplication is a rare condition often found incidentally; most of these detected on screening Ultrasonography (USG) for abdominal colic. Nuclear hepatobiliary scan, popularly known as hepatobiliary iminodiacetic acid (HIDA) scan, with its biliary kinetics, is highly specific for picking up abnormalities related to biliary tract and GB. We report two cases of duplication of GB visualized on HIDA scan. First case highlights the role of HIDA scan in diagnosis of duplicated GB, where USG was equivocal with a number of differentials, whereas in the second case, HIDA helped to rule out obstruction in this case of duplicated GB identified on USG; ruling out biliary cause for the abdominal colic

    The feasibility of developing bladder cancer detection methods using intrinsic tissue optical properties is the focus of this investigation. In vitro experiments have been performed using polarized elastic light scattering in combination with tissue autofluorescence in the NIR spectral region under laser excitation in the green and red spectral regions. The experimental results obtained from a set of tissue specimens from 25 patients reveal the presence of optical fingerprint characteristics suitable for cancer detection with high contrast and accuracy. These photonic methods are compatible with existing endoscopic imaging modalities which make them suitable for in-vivo application.

  4. Automatic bladder segmentation on CBCT for multiple plan ART of bladder cancer using a patient-specific bladder model

    International Nuclear Information System (INIS)

    In multiple plan adaptive radiotherapy (ART) strategies of bladder cancer, a library of plans corresponding to different bladder volumes is created based on images acquired in early treatment sessions. Subsequently, the plan for the smallest PTV safely covering the bladder on cone-beam CT (CBCT) is selected as the plan of the day. The aim of this study is to develop an automatic bladder segmentation approach suitable for CBCT scans and test its ability to select the appropriate plan from the library of plans for such an ART procedure. Twenty-three bladder cancer patients with a planning CT and on average 11.6 CBCT scans were included in our study. For each patient, all CBCT scans were matched to the planning CT on bony anatomy. Bladder contours were manually delineated for each planning CT (for model building) and CBCT (for model building and validation). The automatic segmentation method consisted of two steps. A patient-specific bladder deformation model was built from the training data set of each patient (the planning CT and the first five CBCT scans). Then, the model was applied to automatically segment bladders in the validation data of the same patient (the remaining CBCT scans). Principal component analysis (PCA) was applied to the training data to model patient-specific bladder deformation patterns. The number of PCA modes for each patient was chosen such that the bladder shapes in the training set could be represented by such number of PCA modes with less than 0.1 cm mean residual error. The automatic segmentation started from the bladder shape of a reference CBCT, which was adjusted by changing the weight of each PCA mode. As a result, the segmentation contour was deformed consistently with the training set to fit the bladder in the validation image. A cost function was defined by the absolute difference between the directional gradient field of reference CBCT sampled on the corresponding bladder contour and the directional gradient field of validation

    This study examines the importance of food prices and restaurant and food store outlet availability for child body mass index (BMI). We use the 1998, 2000 and 2002 waves of the child-mother merged files from the 1979 cohort of the National Longitudinal Survey of Youth combined with fruit and vegetable and fast food price data obtained from the American Chamber of Commerce Researchers Association and outlet density data on fast food and full-service restaurants and supermarkets, grocery stores and convenience stores obtained from Dun & Bradstreet. Using a random effects estimation model, we found that a 10% increase in the price of fruits and vegetables was associated with a 0.7% increase in child BMI. Fast food prices were not found to be statistically significant in the full sample but were weakly negatively associated with BMI among adolescents with an estimated price elasticity of -0.12. The price estimates were robust to whether we controlled for outlet availability based on a per capita or per land area basis; however, the association between food outlets and child BMI differed depending on the definition. The associations of fruit and vegetable and fast food prices with BMI were significantly stronger both economically and statistically among low- versus high-socioeconomic status children. The estimated fruit and vegetable and fast food price elasticities were 0.14 and -0.26, respectively, among low-income children and 0.09 and -0.13, respectively, among children with less educated mothers.

    Full Text Available Background. Lymphoma of the urinary bladder (LUB is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18(q21: 21. Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions.

    Brusasco, Vito; Martinez, Fernando

    2014-01-01

    COPD is characterized by airflow limitation that is not fully reversible. The morphological basis for airflow obstruction results from a varying combination of obstructive changes in peripheral conducting airways and destructive changes in respiratory bronchioles, alveolar ducts, and alveoli. A reduction of vascularity within the alveolar septa has been reported in emphysema. Typical physiological changes reflect these structural abnormalities. Spirometry documents airflow obstruction when the FEV1/FVC ratio is reduced below the lower limit of normality, although in early disease stages FEV1 and airway conductance are not affected. Current guidelines recommend testing for bronchoreversibility at least once and the postbronchodilator FEV1/FVC be used for COPD diagnosis; the nature of bronchodilator response remains controversial, however. One major functional consequence of altered lung mechanics is lung hyperinflation. FRC may increase as a result of static or dynamic mechanisms, or both. The link between dynamic lung hyperinflation and expiratory flow limitation during tidal breathing has been demonstrated. Hyperinflation may increase the load on inspiratory muscles, with resulting length adaptation of diaphragm. Reduction of exercise tolerance is frequently noted, with compelling evidence that breathlessness and altered lung mechanics play a major role. Lung function measurements have been traditionally used as prognostic indices and to monitor disease progression; FEV1 has been most widely used. An increase in FVC is also considered as proof of bronchodilatation. Decades of work has provided insight into the histological, functional, and biological features of COPD. This has provided a clearer understanding of important pathobiological processes and has provided additional therapeutic options. PMID:24692133

    Compared with the stimulating food given orally in the gall bladder function test the administration of the decapeptide Ceruletid which is related with Cholecystokinin has the advantage of avoiding resorption disturbances in the upper gastrointestinal tract. To 100 patients with positive peroral cholecystography, Ceruletid was injected i.m. in a dose of 0.4 ..mu..g/kg body weight. The contrasting of the main bile duct was thus increased from 10% to 86%. The oral stimulating food brings an increase to appr. 20%. A special importance is assigned to the frequent diagnosis of adenomyomatoses which, with 6%, lies significantly above the 0.8% achieved by means of the oral stimulating food. More contractile segments of the gall bladder wall can cause pain symptoms which are typical for the biliary tract. Adenomyomatoses in the region of the infundibulum of the gall bladder cause colicky pains and are, as generally accepted, an absolute indication for a surgical intervention. The finding of small gall bladder concrements is often connected with a strong diminution of the gall bladder in order to prevent the small concrements from being overlapped by the non-contrasting bladder bile. Therefore, the application of Ceruletid should be considered also within the frame of the intravenous cholegraphy, thinking of the large number of normal gall bladder findings which were obtained with the oral stimulating food as the only diagnostical help.

    Urinary bladder cancer is a heterogeneous disease with a variety of pathologic features, cytogenetic characteristics, and natural histories. It is the fourth most common cancer in males and the tenth most common cancer in females. Urinary bladder cancer has a high recurrence rate, necessitating long-term surveillance after initial therapy. Early detection is important, since up to 47% of bladder cancer-related deaths may have been avoided. Conventional computed tomography (CT) and magnetic resonance (MR) imaging are only moderately accurate in the diagnosis and local staging of bladder cancer, with cystoscopy and pathologic staging remaining the standards of reference. However, the role of newer MR imaging sequences (eg, diffusion-weighted imaging) in the diagnosis and local staging of bladder cancer is still evolving. Substantial advances in MR imaging technology have made multiparametric MR imaging a feasible and reasonably accurate technique for the local staging of bladder cancer to optimize treatment. In addition, whole-body CT is the primary imaging technique for the detection of metastases in bladder cancer patients, especially those with disease that invades muscle. PMID:22411938

    @@ Approximately 400 million people worldwide suffer from bladder disease such as congenital abnormalities, cancer, trauma, infection, iatrogenic injuries or other conditions which may lead to painful bladder damage or loss, so eventual bladder augmentation or substitution should be required. Gastrointestinal segments are commonly used as tissues for bladder replacement or repair, but have been associated with multiple complications such as infection, metabolic disturbances, increased mucus production, and malignancy.1 Because of the problems encountered with the use of gastrointestinal segments, several bladder substitutes have been attempted with both organic materials (skin, dura mater, peritoneum or fascia) and synthetics (such as poly vinyl, sponge, silicone). These attempts have usually failed due to mechanical, structural or biocompatibility problems. Permanent synthetic materials succumb to mechanical failure and urinary stone formation. Degradable materials lead to fibroblast deposition, scarring, and a reduced reservoir volume.2,3 It is evident that bladder tissue cannot be replaced easily due to its elastic properties and urothelial permeability function.

  1. Malignant biliary obstruction

    International Nuclear Information System (INIS)

    This paper assesses the value of CT in predicting surgical resectability of tumors in patients with malignant biliary obstruction. A retrospective analysis was performed on 320 consecutive patients with malignant biliary obstruction over a 3-1/2-year period. Most patients were treated nonoperatively. Fifty-one patients fulfilled the selection criteria of surgical exploration, pathological confirmation of malignancy, and prepoperative CT scans available for review. The CT scans were reviewed by a blinded reader and assessed for surgical resectability of tumors. There were 32 patients with pancreatic adenocarcinoma, 6 with ampullary carcinoma, 5 with cholangiocarcinoma, 2 with gallbladder carcinoma, and 6 with other pathologic diagnoses.

    Full Text Available The purpose of this study is to analyze a cohort of 46 cases of congenital duodenal obstruction, operated on between 1996 and 2002, 23 of them being diagnosed in neonatal period. In one case, the diagnosis was made antenatally, by ultrasonography. There were 15 males and 8 females, 17 with duodenal atresia and 6 with duodenal diaphragmatic stenosis. Surgery was performed in all cases, consisting in lateral duodeno-duodenal anastomosis in 5 cases and "diamond-shape" duodeno-duodenal anastomosis in 18 cases. The survival rate in this study was 69.5%. 12 cases (52,1% had other congenital pathologies: trisomy 21 (6 cases, multiple ileal atresia (2 cases, dextrocardy (2 cases, omphalocel (1 case, situs inversus (1 case. The complications of surgery were: anastomotic leaking with peritonitis, biliary fistula, intestional adhesions with occlusion. Congenital duodenal obstruction (midgut volvulus, atresia, stenosis remains a challenging issue for pediatric surgeons, especially in our country, due to limited possibilities of quick diagnosis and treatment of associated anomalies.

    Cases of bladder leiomyosarcoma represent 0.1% of all nonurothelial tumors. We present a case report of a 73-year-old man who underwent a radical cystoprostatectomy for a high-grade bladder leiomyosarcoma with an ileal diversion. The patient recovered uneventfully and no surgical margins were verified in final pathology. Early follow-up at 3 months shows no signs of computed tomography recurrence and adequate adaptation to ileal diversion. Although bladder sarcomas were once thought to have a grim prognosis, recent studies suggest that adequate surgical treatment is able to achieve optimal cancer control outcomes. PMID:26839792

    Bladder exstrophy is a rare malformation characterized by an infra-umbilical abdominal wall defect, incomplete closure of the bladder with mucosa continuous with the abdominal wall, epispadias, and alterations in the pelvic bones and muscles. It is part of the exstrophy-epispadias complex, with cloacal exstrophy on the severe and epispadias on the mild ends of the spectrum. Bladder exstrophy is the most common of these entities and is more common in boys. The goal of this paper is to describe common methods of repair and to provide an imaging review of the postoperative appearances. (orig.)

    A turbofan gas turbine engine includes a forward fan section with a row of fan rotor blades, a core engine, and a fan bypass duct downstream of the forward fan section and radially outwardly of the core engine. The forward fan section has only a single stage of variable fan guide vanes which are variable fan outlet guide vanes downstream of the forward fan rotor blades. An exemplary embodiment of the engine includes an afterburner downstream of the fan bypass duct between the core engine and an exhaust nozzle. The variable fan outlet guide vanes are operable to pivot from a nominal OGV position at take-off to an open OGV position at a high flight Mach Number which may be in a range of between about 2.5-4+. Struts extend radially across a radially inwardly curved portion of a flowpath of the engine between the forward fan section and the core engine.

    Resistance at the ice-bed interface provides a strong control on the response of ice streams and outlet glaciers to external forcing, yet it is not observable by remote sensing. We used inverse methods constrained by satellite observations to infer the basal resistance to flow underneath three of the Greenland Ice Sheet's largest outlet glaciers. In regions of fast ice flow and high (>250 kPa) driving stresses, ice is often assumed to flow over a strong bed. We found, however, that the beds of these three glaciers provide almost no resistance under the fast-flowing trunk. Instead, resistance to flow is provided by the lateral margins and stronger beds underlying slower-moving ice upstream. Additionally, we found isolated patches of high basal resistivity within the predominantly weak beds. Because these small-scale (tested their robustness to different degrees of regularization.

    2010-11-01

    Full Text Available A stilling basins are transition structures constructed to dissipate excess energy confined by high velocity flow at the outlet of conduit or tunnel so that the flow beyond the basin does not endanger the stability of bed and banks of downstream channel. In a stilling basin kinetic energy causes turbulences and it is ultimately lost as heat and sound energy. there are several types of stilling basins which are used in various hydraulic structures like dam, canal, culvert etc. The type of stilling basin most suitable at a particular location mainly depends upon initial Froude Number and initial velocity of flow. This paper covers design principles and features of various stilling basins used for outlet works.

    A study which is composed of computational simulation and experimental validation has been conducted for implementation of small, vane type geometries at freezer air outlets, similar to microvortex generators used in aircraft wings, in order to improve the heat transfer efficiency inside the freezer compartment by decreasing airside thermal resistance and improving the air distribution. Both simulation and experimental validation were performed in a loaded condition which was prepared according to `Household refrigerating appliances - characteristics and test methods - IEC 62552 [1]. Solutions for the incompressible K-epsilon (k-ɛ) turbulence model obtained for Bosch KDN 49 refrigerator freezer both with and without airshufflers at air outlets, which are similar to vane type microvortex generators with different geometric dimensions. The airshuffler dimensions were chosen with design of experiment (DOE) principles for finding the optimum geometry. The best combinations were tested according to cooling rate inside freezer compartment. Results were evaluated for feasibility of implementing of vortex generating surfaces (airshufflers) for cooling appliances.

  12. Boundary conditions for free surface inlet and outlet problems

    KAUST Repository

    Taroni, M.

    2012-08-10

    We investigate and compare the boundary conditions that are to be applied to free-surface problems involving inlet and outlets of Newtonian fluid, typically found in coating processes. The flux of fluid is a priori known at an inlet, but unknown at an outlet, where it is governed by the local behaviour near the film-forming meniscus. In the limit of vanishing capillary number Ca it is well known that the flux scales with Ca 2/3, but this classical result is non-uniform as the contact angle approaches π. By examining this limit we find a solution that is uniformly valid for all contact angles. Furthermore, by considering the far-field behaviour of the free surface we show that there exists a critical capillary number above which the problem at an inlet becomes over-determined. The implications of this result for the modelling of coating flows are discussed. © 2012 Cambridge University Press.

    1981-02-01

    Thirty-four patients who received radiation therapy for carcinoma of the cervix developed hydronephrosis. Twelve of 34 (35%) had no evidence of pelvic malignancy, and the obstruction was caused by periureteral fibrosis. The incidence of obstructive uropathy due to periureteral fibrosis not associated with recurrent tumor increased when the obstructing lesion was unilateral, the clinical staging of the cervical carcinoma prior to therapy was Stage IB or Stage II rather than Stage III or Stage IV, and the obstructing lesion appeared 2 or more years after the completion of radiation therapy. The appearance of hydronephrosis in association with ipsilateral leg edema, and sciatic pain in these patients strongly suggest a recurrent tumor. The diagnosis of periureteral fibrosis should be considered in all patients who develop obstruction of the urinary tract after radiation therapy for carcinoma of the cervix. Laparotomy is indicated if all other methods of investigation fail to confirm the presence of a malignant lesion.

  16. Simulation of water flows in multiple columns with small outlets

    International Nuclear Information System (INIS)

    High-pressure die casting such as thixocasting and rheocasting is an effective process in the manufacturing automotive parts. Following the recent trend in the automotive manufacturing technologies, the product design subject to the die casting becomes more and more complex. Simultaneously the injection speed is also designed to be very high to establish a short cycle-time. Thus, the requirement of the die design becomes more demanding than ever before. In some cases the product's shape can have multiple slender manifolds. In such cases, design of the inlet and outlet parts of the die is very important in the whole manufacturing process. The main issues required for the qualified products are to attain gentle and uniform flow of the molten liquid within the passages of the die. To satisfy such issues, the inlet cylinder ('bed cylinder' in this paper) must be as large as possible and simultaneously the outlet opening at the end of each passage must be as small as possible. However these in turn obviously bring additional manufacturing costs caused by re-melting of the bed cylinder and increased power due to the small outlet-openings. The purpose of this paper is to develop effective simulation methods of calculation for fluid flows in multiple columns, which mimic the actual complex design, and to get some useful information which can give some contributions to the die-casting industry. We have used a commercial code CFX in the numerical simulation. The primary parameter involved is the size of the bed cylinder. We will show how the very small opening of the outlet can be treated with the aid of the porous model provided in the code. To check the validity of the numerical results we have also conducted a simple experiment by using water

  20. Bladder filling variation during radiation treatment of prostate cancer: Can the use of a bladder ultrasound scanner and biofeedback optimize bladder filling?

    International Nuclear Information System (INIS)

    Purpose: To investigate the use of a bladder ultrasound scanner in achieving a better reproducible bladder filling during irradiation of pelvic tumors, specifically prostate cancer. Methods and Materials: First, the accuracy of the bladder ultrasound scanner relative to computed tomography was validated in a group of 26 patients. Next, daily bladder volume variation was evaluated in a group of 18 patients. Another 16 patients participated in a biofeedback protocol, aiming at a more constant bladder volume. The last objective was to study correlations between prostate motion and bladder filling, by using electronic portal imaging device data on implanted gold markers. Results: A strong correlation between bladder scanner volume and computed tomography volume (r = 0.95) was found. Daily bladder volume variation was very high (1 Sd = 47.2%). Bladder filling and daily variation did not significantly differ between the control and the feedback group (47.2% and 40.1%, respectively). Furthermore, no linear correlations between bladder volume variation and prostate motion were found. Conclusions: This study shows large variations in daily bladder volume. The use of a biofeedback protocol yields little reduction in bladder volume variation. Even so, the bladder scanner is an easy to use and accurate tool to register these variations

Patients with bladder cancer have a 1% to 4% incidence of synchronous or metachronous upper t ract urothelial tumors. There are many risk factors for urothelial cancer, classified into (1 Genetic (2 chemical exposure, and (3 chronic irritation. Genetic abnormalities associated with CIS include alterations in the retinoblastoma gene (Rb, p53, an d PTEN. Chemical exposure has the most epidemiologic evidence to support it as an inciting agent (Aromatic amines, aniline dyes, and nitrites and nitrates. Chronic irritants include catheters, recurrent urinary track infections, Schistosoma haematobium, a nd irradiation. There are many studies that suggest high water consumption, vitamin intake, and various diets that are beneficial in preventing bladder cancer. However, none of these have shown any clear benefit with respect to prevention.

  10. [Follow-up after surgical replacement of the urinary bladder (urinary diversion)].

    Science.gov (United States)

    Ubrig, B; Kories, C; Roth, S

    2013-01-01

    Surgical replacement of the urinary bladder is usually necessary after radical cystectomy for muscle invasive bladder cancer. Besides uro-oncological follow-up (local, urethral, and systemic recurrence; tumor in the upper tract) functional follow-up of the urinary diversion is indicated. Guidelines are still scarce. Long contact time and large surface area in continent pouches made from long intestinal segments lead to absorption of contents of urine and thus to acidosis and imbalances in serum electrolytes. Compensation depends on renal function. Exclusion of long ileal segments out of the intestinal passage may lead to malabsorption of Vitamin B12 and bile acids. 30 % and more of long-term survivors with continent pouches take Vitamin B12 and sodium bicarbonate. Special attention has to be paid to obstruction of the upper urinary tract, total renal function and to secondary malignancy in the bladder substitute. For the latter, sigma-rectum pouches, augmentation cystoplasties and continent pouches with incorporation of colonic segments are at special risk. Functional follow-up affords good understanding of the specific complications of the different types of urinary diversions. PMID:23386377

  11. Holmium laser lithotripsy of bladder calculi

    1998-07-01

    Although the overall incidence of bladder calculi has been decreasing, it is still a significant disease affecting adults and children. Prior treatment options have included open cystolitholapaxy, blind lithotripsy, extracorporeal shock wave lithotripsy, and visual lithotripsy with ultrasonic or electrohydraulic probes. The holmium laser has been found to be extremely effective in the treatment of upper tract calculi. This technology has also been applied to the treatment of bladder calculi. We report our experience with the holmium laser in the treatment of bladder calculi. Twenty- five patients over a year and a half had their bladder calculi treated with the Holmium laser. This study was retrospective in nature. Patient demographics, stone burden, and intraoperative and post-operative complications were noted. The mean stone burden was 31 mm with a range of 10 to 60 mm. Preoperative diagnosis was made with either an ultrasound, plain film of the abdomen or intravenous pyelogram. Cystoscopy was then performed to confirm the presence and determine the size of the stone. The patients were then taken to the operating room and given a regional or general anesthetic. A rigid cystoscope was placed into the bladder and the bladder stone was then vaporized using the holmium laser. Remaining fragments were washed out. Adjunctive procedures were performed on 10 patients. These included transurethral resection of the prostate, transurethral incision of the prostate, optic internal urethrotomy, and incision of ureteroceles. No major complications occurred and all patients were rendered stone free. We conclude that the Holmium laser is an effective and safe modality for the treatment of bladder calculi. It was able to vaporize all bladder calculi and provides a single modality of treating other associated genitourinary pathology.

    The management of obstructed defecation syndrome (ODS) is mainly conservative and mainly consists of fiber diet, bulking laxatives, rectal irrigation or hydrocolontherapy, biofeedback, transanal electrostimulation, yoga and psychotherapy. According to our experience, nearly 20% of the patients need surgical treatment. If we consider ODS an "iceberg syndrome", with "emerging rocks", rectocele and rectal internal mucosal prolapse, that may benefit from surgery, at least two out of ten patients also has "underwater rocks" or occult disorders, such as anismus, rectal hyposensation and anxiety/depression, which mostly require conservative treatment. Rectal prolapse excision or obliterative suture, rectocele and/or enterocele repair, retrograde Malone's enema and partial myotomy of the puborectalis muscle are effective in selected cases. Laparoscopic ventral sacral colporectopexy may be an effective surgical option. Stapled transanal rectal resection may lead to severe complications. The Transtar procedure seems to be safer, when dealing with recto-rectal intussusception. A multidisciplinary approach to ODS provides the best results. PMID:25632177

Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    Full Text Available PURPOSE: To study the role of sensory dysfunction of bladder mucosa in bladder oversensitivity of rats with metabolic syndrome. MATERIALS AND METHODS: Female Wistar rats were fed a fructose-rich diet (60% or a normal diet for 3 months. Based on cystometry, the fructose-fed rats (FFRs were divided into a group with normal detrusor function or detrusor overactivity (DO. Acidic adenosine triphosphate (ATP solution (5mM, pH 3.3 was used to elicit reflex micturition. Cystometric parameters were evaluated before and after drug administration. Functional proteins of the bladder mucosa were assessed by western blotting. RESULTS: Compared to the controls, intravesical acidic ATP solution instillation induced a significant increase in provoked phasic contractions in both FFR groups and a significant decrease in the mean functional bladder capacity of group DO. Pretreatment with capsaicin for C-fiber desentization, intravesical liposome for mucosal protection, or intravenous pyridoxal 5-phosphate 6-azophenyl-2',4'-disulfonic acid for antagonized purinergic receptors can interfere with the urodynamic effects of intravesical ATP in FFRs and controls. Over-expression of TRPV1, P2X(3, and iNOS proteins, and down-regulation of eNOS proteins were observed in the bladder mucosa of both fructose-fed groups. CONCLUSIONS: Alterations of sensory receptors and enzymes in the bladder mucosa, including over-expression of TRPV1, P2X(3, and iNOS proteins, can precipitate the emergence of bladder phasic contractions and oversensitivity through the activation of C-afferents during acidic ATP solution stimulation in FFRs. The down-regulation of eNOS protein in the bladder mucosa of FFRs may lead to a failure to suppress bladder oversensitivity and phasic contractions. Sensory dysfunction of bladder mucosa and DO causing by metabolic syndrome are easier to elicit bladder oversensitivity to certain urothelium stimuli.

    Bladder augmentation (also called augmentation cystoplasty) refers to a number of surgical methods that increase the capacity and compliance of the urinary bladder. Imaging has an important role in the postoperative evaluation of bladder augmentation. The most common augmentation procedures utilize enteric segments to augment the bladder. The various types of bladder augmentation have characteristic appearances on different imaging modalities. Spontaneous bladder perforation is a complication that is seen in both early and late post-operative periods and it is one of the most important complications for radiologists to be aware of as it is life-threatening. We review the indications for bladder augmentation in children, the surgical techniques employed, the normal postoperative appearances on imaging studies and the role of imaging complications of bladder augmentation including delayed spontaneous bladder rupture, which is life-threatening.

    Decompression of the biliary system in patients with malignant biliary obstruction has been widely accepted and implemented as part of the care. Despite a wealth of literature, there remains a significant amount of uncertainty as to which approach would be most appropriate in different clinical settings. This review covers stenting of the biliary system in cases of resectable or palliative malignant biliary obstruction, potential candidates for biliary drainage, technical aspects of the procedure, as well as management of biliary stent dysfunction. Furthermore, periprocedural considerations including proper mapping of the location of obstruction and the use of antibiotics are addressed. PMID:26431598

    Objective: To evaluate the results of a self-designed bladder controller for restoring micturition function in paraplegic dogs.Methods: The spinal cords of 4 dogs were transected above the cone. Electrodes were implanted in S2 bilaterally and connected to the subcutaneous receivers for external activation. Microsurgical technique was employed to perform dorsal rhizotomy of S1-3 intradurally. The dogs were stimulated daily to observe micturition. Urodynamic testing and vesicography were performed. Results: All the dogs acquired micturition under the control of electric stimulation, with urine volume 80-140 ml per time. The mode of micturition was post-stimulus voiding. Vesicography revealed that the bladder was filled well and the bladder neck was open in the micturition course of electric stimulation. Residual urine volume was 15-20 ml. Urodynamic testing found that the bladder pressure and intraurethral pressure increased simultaneously, but when the intraurethral pressure was greater than the bladder pressure, no micturition occurred. The pressure decreased to baseline rapidly and the bladder pressure decreased slowly between two bursts. Micturition occurred when the bladder pressure was greater than the intraurethral pressure.Conclusions: The self-designed bladder controller together with a sacral deafferentation procedure can restore micturition function of paraplegic dogs.

    Renal vein thrombosis (RVT) is an uncommon condition in adults and may be caused by endothelial damage, stasis, or hypercoagulable states. RVT is commonly identified in patients with nephrotic syndrome or malignancy. We present the case of a 57-yearold man with no past medical history who presented with a 1-month history of abdominal pain, dysuria, and hematuria. Initial laboratory studies were consistent with acute kidney injury (AKI). Imaging revealed bladder distension, enlargement of the prostate, bilateral hydronephrosis, and left renal vein thrombosis extending into the inferior vena cava. His renal failure and presenting symptoms resolved with placement of a Foley catheter and ureteral stent. The patient was discharged on anticoagulation. Here, we report a rare case of RVT that appears to have occurred as a consequence of obstructive uropathy causing massive bladder distention resulting in compression of the renal vein. PMID:25707456

    2012-03-01

    An adult female bottlenose dolphin (Tursiops truncatus) presented with acute anorexia secondary to progressive azotemia (blood urea nitrogen = 213 mg/dl, creatinine [Cr] = 9.5 mg/dl) and electrolyte abnormalities (K = 7.4 mEq/L). It was later diagnosed with postrenal obstruction secondary to bilaterally obstructing ureteral calculi seen on ultrasound. Treatment of the obstruction required two endoscopic procedures, cystoscopy for ureteral stent placement and ureteroscopy to perform intracorporeal lithotripsy on the obstructing calculi. Before the first procedure, the dolphin's azotemia was stabilized with aggressive fluid therapy, peritoneal dialysis, and treatment for acidosis. Diuresis subsequent to the fluid therapy enabled passage of the right obstructing urolith. For both endoscopic procedures, the dolphin was placed in left lateral recumbency due to the peritoneal dialysis catheter in the right retroperitoneal region. For the first procedure, a 12-French (Fr) flexible cystoscope was inserted retrograde into the bladder via the urethra, whereupon a calculus was seen obstructing the left ureteral orifice. A 4.8-Fr, 26-cm double-pigtail ureteral stent was placed up the left ureter to relieve the postrenal obstruction. Inadvertent proximal migration of the left ureteral stent occurred during the procedure. However, renal parameters (serum Cr = 5.8, K = 5.4) improved significantly by the next day. For the second procedure, 28 hr later, ureteroscopy was performed to treat the calculus and replace the existing stent with a longer stent. The left ureteral calculus was pulverized into tiny fragments by using a holmium:yttrium-aluminum-garnet laser inserted through a 6.9-Fr semirigid ureteroscope. The migrated stent was visualized in the distal left ureter and replaced with a 90-cm single-pigtail ureteral stent that was sutured exterior to the urogenital slit and removed 3 days later. Renal function normalized over the next several days, and the dolphin recovered over

  12. PPOOLEX experiments with a modified blowdown pipe outlet

    International Nuclear Information System (INIS)

    This report summarizes the results of the experiments with a modified blowdown pipe outlet carried out with the PPOOLEX test facility designed and constructed at Lappeenranta University of Technology. Steam was blown into the dry well compartment and from there through a vertical DN200 blowdown pipe to the condensation pool. Four reference experiments with a straight pipe and ten with the Forsmark type collar were carried out. The main purpose of the experiment series was to study the effect of a blowdown pipe outlet collar design on loads caused by chugging phenomena (rapid condensation) while steam is discharged into the condensation pool. The PPOOLEX test facility is a closed stainless steel vessel divided into two compartments, dry well and wet well. During the experiments the initial temperature level of the condensation pool water was either 20-25 or 50-55 deg. C. The steam flow rate varied from 400 to 1200 g/s and the temperature of incoming steam from 142 to 185 deg. C. In the experiments with 20-25 deg. C pool water, even 10 times higher pressure pulses were measured inside the blowdown pipe in the case of the straight pipe than with the collar. In this respect, the collar design worked as planned and removed the high pressure spikes from the blowdown pipe. Meanwhile, there seemed to be no suppressing effect on the loads due to the collar in the pool side in this temperature range. Registered loads in the pool were approximately in the same range (or even a little higher) with the collar as with the straight pipe. In the experiments with 50-55 deg. C pool water no high pressure pulses were measured inside the blowdown pipe either with the straight pipe or with the collar. In this case, more of the suppressing effect is probably due to the warmer pool water than due to the modified pipe outlet. It has been observed already in the earlier experiments with a straight pipe in the POOLEX and PPOOLEX facilities that warm pool water has a diminishing effect on

    The lethality of invasive transitional cell carcinoma (TCC) has prompted a search for effective, minimally toxic, adjuvant therapy. Such agents were evaluated in a murine bladder cancer (MBT2) model which parallels the clinical disease. One hundred C3H/He mice were inoculated i.d. with 2.5 x 10(4) viable MBT2 tumor cells and randomized to receive either normal saline (control), cis-Platinum (CPT), cyclophosphamide (CY), methotrexate (MTX), BCG, (CY + MTX), or (CY + MTX + BCG). Chemotherapy was given intraperitoneally weekly starting on day 7 after inoculation. Immunotherapy was given intralesionally on days 1 and 10 only. All mice were treated for 5 weeks followed by 5 weeks of observation. At 5 weeks, tumors of mice receiving cyclophosphamide alone or either of the combinations of therapy were smaller (P less than 0.01) than tumors of controls or other single agents alone. Each regimen increased survival, but only the combination regimen increase survival significantly (P less than 0.01). In the doses and schedule used in this model. Combination chemotherapy and chemoimmunotherapy significantly delay tumor growth and increase duration of survival (P less than 0.01) when compared with controls or single agent groups. PMID:7298287

    The goal of the present study was to determine if supraspinal pathways are necessary for inhibition of bladder reflex activity induced by activation of somatic afferents in the pudendal or tibial nerve. Cats anesthetized with α-chloralose were studied after acute spinal cord transection at the thoracic T9/T10 level. Dilute (0.25%) acetic acid was used to irritate the bladder, activate nociceptive afferent C-fibers, and trigger spinal reflex bladder contractions (amplitude: 19.3 ± 2.9 cmH2O). Hexamethonium (a ganglionic blocker, intravenously) significantly (P < 0.01) reduced the amplitude of the reflex bladder contractions to 8.5 ± 1.9 cmH2O. Injection of lidocaine (2%, 1-2 ml) into the sacral spinal cord or transection of the sacral spinal roots and spinal cord further reduced the contraction amplitude to 4.2 ± 1.3 cmH2O. Pudendal nerve stimulation (PNS) at frequencies of 0.5-5 Hz and 40 Hz but not at 10-20 Hz inhibited reflex bladder contractions, whereas tibial nerve stimulation (TNS) failed to inhibit bladder contractions at all tested frequencies (0.5-40 Hz). These results indicate that PNS inhibition of nociceptive afferent C-fiber-mediated spinal reflex bladder contractions can occur at the spinal level in the absence of supraspinal pathways, but TNS inhibition requires supraspinal pathways. In addition, this study shows, for the first time, that after acute spinal cord transection reflex bladder contractions can be triggered by activating nociceptive bladder afferent C-fibers using acetic acid irritation. Understanding the sites of action for PNS or TNS inhibition is important for the clinical application of pudendal or tibial neuromodulation to treat bladder dysfunctions. PMID:25056352

    Associated to any supermanifold is a filtration by spaces, referred to as thickenings. It is the objective of this paper to study them up to a certain equivalence and then up to isomorphism in the complex-analytic setting. We study them both in the presence and absence of a complex supermanifold and will be guided by the goal to clarify and address the question: when does a given thickening come from a supermanifold? Such a question was, in principle, first studied by Eastwood and LeBrun. In this paper we begin with a pedagogical account of their study, after which we further develop the theory of thickenings in the context of supergeometry. Our intent will be in recovering results reminiscent of those one finds in studies on deformation theory. As a complement to our study here, we comment on the moduli problem for complex supermanifolds and consider the analogous problem for thickenings. Finally, we conclude with some illustrations of obstructed thickenings on the complex projective plane.

    Full Text Available Obstructive sleep apnea (OSA affects millions of Americans and is estimated to be as prevalent as asthma and diabetes. Given the fact that obesity is a major risk factor for OSA, and given the current global rise in obesity, the prevalence of OSA will increase in the future. Individuals with sleep apnea are often unaware of their sleep disorder. It is usually first recognized as a problem by family members who witness the apneic episodes or is suspected by their primary care doctor because of the individual’s risk factors and symptoms. The vast majority remain undiagnosed and untreated, despite the fact that this serious disorder can have significant consequences. Individuals with untreated OSA can stop breathing hundreds of times a night during their sleep. These apneic events can lead to fragmented sleep that is of poor quality, as the brain arouses briefly in order for the body to resume breathing. Untreated, sleep apnea can have dire health consequences and can increase the risk of hypertension, diabetes, heart disease, and heart failure. OSA management has also become important in a number of comorbid neurological conditions, including epilepsy, stroke, multiple sclerosis, and headache. Diagnosis typically involves use of screening questionnaires, physical exam, and an overnight polysomnography or a portable home study. Treatment options include changes in lifestyle, positive airway pressure, surgery, and dental appliances.

  20. Posterior urethral obstruction: Prenatal sonographic findings and clinical outcome in 12 cases

    International Nuclear Information System (INIS)

    Twelve cases of fetal urethral obstruction were reviewed retrospectively. A dilated posterior urethra was identified in eight fetuses (67%) and an enlarged bladder in 11 (92%). Ureterectasis, pyelocalicectasis, increased renal echogenicity, and renal cysts suggest abnormal renal development. Ureterectasis was demonstrated in seven fetuses (58%) and pyelocalicectasis in ten (83%). Renal echogenicity was increased in eight of ten cases (80%) and renal cysts were identified in two cases. Decreased amniotic fluid volume complicated ten pregnancies (83%). There were six live births, but only two neonates survived more than 5 weeks. Pulmonary immaturity contributed to the four postnatal deaths

  1. Technologies for Upgrading Light Water Reactor Outlet Temperature

    2013-07-01

    Nuclear energy could potentially be utilized in hybrid energy systems to produce synthetic fuels and feedstocks from indigenous carbon sources such as coal and biomass. First generation nuclear hybrid energy system (NHES) technology will most likely be based on conventional light water reactors (LWRs). However, these LWRs provide thermal energy at temperatures of approximately 300°C, while the desired temperatures for many chemical processes are much higher. In order to realize the benefits of nuclear hybrid energy systems with the current LWR reactor fleets, selection and development of a complimentary temperature upgrading technology is necessary. This paper provides an initial assessment of technologies that may be well suited toward LWR outlet temperature upgrading for powering elevated temperature industrial and chemical processes during periods of off-peak power demand. Chemical heat transformers (CHTs) are a technology with the potential to meet LWR temperature upgrading requirements for NHESs. CHTs utilize chemical heat of reaction to change the temperature at which selected heat sources supply or consume thermal energy. CHTs could directly utilize LWR heat output without intermediate mechanical or electrical power conversion operations and the associated thermodynamic losses. CHT thermal characteristics are determined by selection of the chemical working pair and operating conditions. This paper discusses the chemical working pairs applicable to LWR outlet temperature upgrading and the CHT operating conditions required for providing process heat in NHES applications.

    Functional impairment and pain in the upper extremities may indicate a functional deficit in the thoracic outlet. Static work posture, trauma and whiplash injury may be predisposing factors. The younger generation who often spend long hours in front of a computer are in danger of becoming a future risk group. The primary care physician should be familiar with the syndrome which can be identified by careful clinical examination. Timely intervention can prevent much of the disabling symptomatology. Treatment is primarily conservative and should be aimed at the restoration of functional capacity. As in other disorders, the individual constellation of symptoms is dependent on circumstantial factors, an aspect meriting particular attention in treatment and follow-up. Optimisation of ergonomic conditions is important feature of treatment, and long-term follow-up is necessary. Transient exacerbation is not an indication for surgical treatment. If cervical and thoracic outlet function has normalised but the patient still has symptoms, then the differential diagnosis should be reconsidered. Examination and treatment of patients with pain in the upper extremities requires the collaboration of the physician and physical and occupational therapists. Treatment can be delivered in the primary care setting. PMID:9411397

    Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals - including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years. PMID:27176184

  4. Effects of urinary bladder distention on location of the urinary bladder and urethra of healthy dogs and cats

    International Nuclear Information System (INIS)

    Evaluation of the anatomic location of the distended and empty urinary bladders and urethras of healthy adult male and female dogs and cats by retrograde urethrocystography revealed substantial variations. In 15 dogs in lateral recumbency with empty bladder lumens, the caudal portion of the urinary bladder was within the pelvic canal in 5 of 7 male and 5 of 8 female dogs. In female dogs examined in ventrodorsal recumbency, only 4 of 8 had the empty urinary bladders in part within the pelvic canal. After luminal distention, 3 of 7 male and 3 of 8 female dogs, while in lateral recumbency, had the urinary bladders in part intrapelvically. However, when female dogs were placed in ventrodorsal recumbency, only 1 of 7 urinary bladders was in part within the pelvis. The urinary bladders of 14 cats were consistently within the abdominal cavity, irrespective of whether the bladder lumen was distended or empty. Urethral flexures occurred in dogs with intrapelvic bladders that were distended or empty. Urethral flexures were not found in cats. The urethras of dogs and cats in lateral recumbency were generally closer to the floor of the pelvis after urinary bladder distention than when the bladder was empty. The urethra of the dogs and cats in ventrodorsal recumbency was to the left or right of or on the midsagittal plane, whether the urinary bladder was empty or distended. A greater degree of lateral displacement was encountered in ventrodorsal recumbency after urinary bladder distention

  5. Bladder emptying by intermittent electrical stimulation of the pudendal nerve

    Persons with a suprasacral spinal cord injury cannot empty their bladder voluntarily. Bladder emptying can be restored by intermittent electrical stimulation of the sacral nerve roots (SR) to cause bladder contraction. However, this therapy requires sensory nerve transection to prevent dyssynergic contraction of the external urethral sphincter (EUS). Stimulation of the compound pudendal nerve trunk (PN) activates spinal micturition circuitry, leading to a reflex bladder contraction without a reflex EUS contraction. The present study determined if PN stimulation could produce bladder emptying without nerve transection in cats anesthetized with α-chloralose. With all nerves intact, intermittent PN stimulation emptied the bladder (64 ± 14% of initial volume, n = 37 across six cats) more effectively than either distention-evoked micturition (40 ± 19%, p 0.10), indicating that PN stimulation was not limited by bladder-sphincter dyssynergia. Intermittent PN stimulation holds promise for restoring bladder emptying following spinal injury without requiring nerve transection.

  11. Chronic phimosis as a cause of obstructive uropathy in an adult patient

    International Nuclear Information System (INIS)

    Phimosis is a rare cause of obstructive uropathy and renal failure. This report presents a case of a 22-year-old man with phimosis, resulting in such complications. The patient with incidentally revealed elevated serum creatinine level was subjected to ultrasonography, voiding cystourethrography and static fluid MR urography (sMRU), combined with conventional T1- and T2-weighted images. The urinary tract dilatation and the bladder diverticula were diagnosed with the use of imaging modalities. Two months after circumcision the degree of hydroureteronephrosis as well as creatinine level decreased. The obstructive uropathy involving the upper urinary tract and resulting in renal failure may develop on the basis of chronic phimosis. Completing of standard imaging techniques with MR urography significantly improved the possibility of the urinary tract evaluation in the presented case. (author)

  12. Small cell carcinoma of the urinary bladder

    International Nuclear Information System (INIS)

    Small cell carcinoma of the urinary bladder (SCCUB) is an extremely rare tumor that exhibits aggressive behavior and accounts for approximately less than 1% of all primary bladder tumors. Small cell carcinoma generally occurs in the lung, accounting for 25% of all pulmonary malignancies. SCCUB exhibits a similar microscopic and immunohistochemical appearance to that of small cell carcinoma of the lung. There is no consensus about the standard therapy, owing to its rarity. Surgical resection seems to be the mainstay of treatment for patients with limited stage, together with neoadjuvant or adjuvant platinum-based chemotherapy. Radiation therapy has same small effect for palliative purposes, as well as being an alternative to radical cystectomy. Patients with advanced stage, although given platinum-based chemotherapy, have a poor prognosis. We herein review epidemiology, clinical presentation, diagnosis, pathological features, and current management of small cell carcinoma of the urinary bladder. (author)

    Full Text Available Amyloidosis is a disease characterised by accumulation of a fibrillar protein called amyloid in the extracellular space. The kidneys, ureters and the bladder can be affected in the urinary tract. However, primary amyloidosis of bladder is a rare entity. Macroscopic hematuria could be the first and only symptom of primary amyloidosis of the bladder; therefore, it has similar findings with urinary tract malignancies. Histopathological evaluation is mandatory for the diagnosis. Follow-up should always include cystoscopic evaluation as recurrence is expected in the natural course.

    Tobacco products are sold in approximately 375,000 US retail outlets, including convenience stores and pharmacies, which often sell energy-dense, low-nutrient foods and beverages. The Food and Drug Administration's (FDA's) increased authority over tobacco product sales and marketing, combined with declining smoking rates, provides an opportunity to transition tobacco retailers toward healthier retail environments. Unfortunately, research into improving consumer retail environments is often conducted in isolation by researchers working in tobacco control, nutrition, and physical activity. Interdisciplinary efforts are needed to transform tobacco retailers from stores that are dependent on a declining product category, to the sale and promotion of healthful foods and creating environments conducive to active living. The objective of this article is to describe the potential for interdisciplinary efforts to transition retailers away from selling and promoting tobacco products and toward creating retail environments that promote healthful eating and active living.

    Some bladder disorders, such as obstructive bladder and hyperactivity, may be caused partly by ischemia/reperfusion injury (I/R). The neuroprotective effects of estrogens were demonstrated in in vitro studies and a great interest in soy isoflavones (genistein and daidzein) as alternative to the synthetic estrogen receptor modulators for therapeutic use has been pointed out. The aim of this study was to investigate the effect of genistein and daidzein, on rat detrusor smooth muscle contractility and their possible neuroprotective role against I/R-like condition. Whole rat urinary bladders were subjected to in vitro anoxia-glucopenia (A-G) and reperfusion (R) in the absence or presence of drugs and response to electrical field stimulation (EFS) of intrinsic nerves evaluated. Furthermore rats were treated in vivo for 1 week with the phytoestrogens and the same in vitro protocol was applied to the ex vivo bladders. Antioxidant activity of genistein and daidzein on the A-G/R model was determined by measuring malonyldialdehyde (MDA). Moreover, hormones plasma levels were determined by radioimmunoassay. Genistein and daidzein administered either in vitro or in vivo showed significant neuroprotective effect and antioxidant activity. Testosterone and 17β-estradiol plasma levels were not modified by daidzein, while a significant decrease of testosterone in genistein treated rats was evident. Moreover both phytoestrogens significantly decreased detrusor contractions induced by EFS in a concentration-dependent manner. For being either neuroprotective and myorelaxant, genistein and daidzein could be considered a good lead for new therapeutic agents to protect the urinary bladder from hyperactivity and nerve damage.

    The aim of the study was to evaluate the role of MR urography (MRU) in the diagnosis of obstructive uropathy in selected groups of patients. The groups involved following pathologies: calculi; strictures of ureteropelvic junction (UPJ); benign and malignancy-induced ureterostenosis. Sixty patients with clinical diagnosis of obstructive uropathy were subjected to static fluid MRU (sMRU) with the use of 3D turbo spin echo (TSE) sequence in a 0.5-T magnet. The examination was completed with conventional MR sequences and in 12 cases additionally with sequences after the administration of Gd-DTPA and excretory MRU. The results were compared with intravenous urography (IVU), CT, US, clinical and histopathological data. The degree of the urinary tract dilatation as well as the level and type of obstruction were estimated. In patients with urolithiasis sMRU correctly depicted the degree of ureterohydronephrosis in 85%, in cases of UPJ stenosis and malignancy-induced ureterostenosis in 100% and in the group of benign ureterostenosis in 91% of patients. Determination of obstruction level in patients with stones was adequate in 92% and in cases of non-calculous ureteral strictures in 100% of patients. The sMRU sequence alone could not specify the nature of obstruction except 1 case of bladder carcinoma. Filling defects in ureters visible on MR urograms were verified with IVU or CT to exclude intrinsic tumours. Completed with conventional MR sequences sMRU enabled the depiction of solid mass or infiltration in 83% cases of malignancy-induced ureterostenosis, and in the remaining groups of patients neoplastic process was excluded in 91%. In conjunction with excretory MRU and conventional MR images sMRU appears to be a highly useful technique in assessment of obstructive uropathy, especially that of non-calculous origin.

    1988-02-01

    Bladder carcinoma is considered one of the most favorable targets for the application of photodynamic therapy (PDT) due to the accessibility of the bladder for light delivery. Examination of the bladder and surgical procedures are routinely performed by the insertion of an optical instrument called cystoscope through the urethra. Thus, the treatment of bladder cancer by PDT can be conducted through the cystoscope with minimal invasion. However, to achieve optimal results from this treatment, one must consider both the structure of the bladder and the nature of the carcinoma.

    2014-01-01

    In this paper, case study on outlet cracking is first conducted for the Goupitan and Xiaowan arch dams. A nonlinear FEM method is then implemented to study effects of the outlets on integral stability of the Xiluodu arch dam under two loading conditions, i.e., normal loading and overloading conditions. On the basis of the case study and the numerical modelling, the outlet cracking mechanism, risk, and corresponding reinforcement measures are discussed. Furthermore, the numerical simulation reveals that (1) under the normal loading conditions, the optimal distribution of the outlets will contribute to the tensile stress release in the local zone of the dam stream surface and decrease the outlet cracking risk during the operation period. (2) Under the overloading conditions, the cracks initiate around the outlets, then propagate along the horizontal direction, and finally coalesce with those in adjacent outlets, where the yield zone of the dam has a shape of butterfly. Throughout this study, a dam outlet cracking risk control and reinforcement principle is proposed to optimize the outlet design, select the appropriate concrete material, strengthen the temperature control during construction period, design reasonable impounding scheme, and repair the cracks according to their classification.

    Stunell, H; Buckley, O; Geoghegan, T; O'Brien, J; Ward, E; Torreggiani, W

    2008-04-01

    Adenomyomatosis is a relatively common abnormality of the gall bladder, with a reported incidence of between 2.8 and 5%. Although mainly confined to the adult study group, a number of cases have been reported in the paediatric study group. It is characterized pathologically by excessive proliferation of the surface epithelium and hypertrophy of the muscularis propria of the gall bladder wall, with invagination of the mucosa into the thickened muscularis forming the so-called 'Rokitansky-Aschoff' sinuses. The condition is usually asymptomatic and is often diagnosed as an incidental finding on abdominal imaging. The radiological diagnosis is largely dependent on the visualization of the characteristic Rokitansky-Aschoff sinuses. As the condition is usually asymptomatic, the importance of making a correct diagnosis is to prevent misinterpretation of other gall bladder conditions such as gall bladder cancer, leading to incorrect treatment. In the past, oral cholecystography was the main imaging method used to make this diagnosis. In most institutions, oral cholecystography is no longer carried out, and the diagnosis is now more commonly seen on cross-sectional imaging. In this review article, we describe the manifestations of adenomyomatosis on the various imaging methods, with an emphasis on more modern techniques such as magnetic resonance cholangiopancreatography. A brief section on oral cholecystography to aid readers familiar with this technique in understanding the comparable imaging features on more modern imaging techniques is included. PMID:18373800

    Mayer, Erik N.; Lenherr, Sara

    2016-01-01

    Neurogenic bladder is a very broad disease definition that encompasses varied disease and injury states affecting the bladder. The majority of patients with neurogenic bladder dysfunction do not have concomitant intrinsic sphincteric deficiency (ISD), but when this occurs the challenges of management of urinary incontinence from neurogenic bladder are compounded. There are no guidelines for surgical correction of ISD in adults and most of the literature on treatment of the problem comes from treatment of children with congenital diseases, such as myelomeningocele. Our goal, in this review, is to present some of the common surgical options for ISD [including artificial urinary sphincters, bladder slings, bladder neck reconstruction (BNR) and urethral bulking agents] and the evidence underlying these treatments in adults with neurogenic bladder.

  9. Bladder sensory desensitization decreases urinary urgency

    2007-06-01

    Full Text Available Abstract Background Bladder desensitization has been investigated as an alternative treatment for refractory detrusor overactivity. Most open and controlled clinical trials conducted with intravesical RTX showed that desensitization delays the appearance of involuntary detrusor contractions during bladder filling and decreases the number of episodes of urgency incontinence. Urgency is being recognised as the fundamental symptom of overactive bladder (OAB, a symptomatic complex which recent epidemiological studies have shown to affect more than 10% of the Western population. As anti-muscarinic drugs, the first line treatment for OAB, are far from being able to fully control urgency, the opportunity to test other therapeutic approaches is created. The present work was, therefore, designed as an exploratory investigation to evaluate the effect of bladder desensitization on urinary urgency. Methods Twenty-three OAB patients with refractory urgency entered, after given informed consent, a 30 days run-in period in which medications influencing the bladder function were interrupted. At the end of this period patients filled a seven-day voiding chart where they scored, using a 0–4 scale, the bladder sensations felt before each voiding. Then, patients were instilled with 100 ml of 10% ethanol in saline (vehicle solution and 30 days later a second seven-day voiding chart was collected. Finally, patients were instilled with 100 ml of 50 nM RTX in 10% ethanol in saline. At 1 and 3 months additional voiding charts were collected. At the end of the vehicle and 3 months period patients were asked to give their subjective impression about the outcome of the treatment and about the willingness to repeat the previous instillation. Results At the end of the run-in period the mean number of episodes of urgency per week was 71 ± 12 (mean ± SEM. After vehicle instillation, the mean number of episodes of urgency was 56 ± 11, but only 4 patients (17% considered

    Full Text Available Objective: To study bladder involvement in systemic lupus erythematosus patients through clinical and laboratorial evaluation, ultrasonography, radiological and endoscopic examination. Methods: Thirty-nine patients, either outpatients or inpatients at the Department of Rheumatology of Hospital das Clínicas da Faculdade de Medicina from Universidade de São Paulo were evaluated as to clinical and laboratorial data. All patients were submitted to ultrasonographic evaluation of the upper urinary tract, radiological and endoscopic examinations of the middle and lower urinary tracts. Rresults: Mean age of patients varied between 13 and 62 years (median = 29 years. Thirty-six were females and three were males. The disease varied from 6 months to 22 years (median three years and one month. Clinical and laboratory activity of the disease was present in 30 patients. Twenty-two patients had the diagnosis of lupus established for three years or more. Twenty-five patients were asymptomatic and all had received corticosteroids for treatment at least once. Twenty-three received antimalarial drugs; ten received cytostatics, and seven patients received non-steroid anti-inflammatory drugs. Upper urinary tract ultrasonography was normal in all cases but one with staghorn calculus associated with neurogenic bladder secondary to neurological involvement by the disease. Vesicoureteral reflux was observed in two cases. Other two patients had significant post-voiding residual urine, both with neurogenic bladder secondary to nervous system involvement by lupus. The average bladder maximum capacity in an awaken patient was 342 mL, and was decreased in 18.9% of cases. This subgroup of patients presented a greater frequency of urinary symptoms and greater use of cytostatic drugs (Z > Z5%. A pathognomonic cystoscopic pattern of bladder involvement in systemic lupus erythematosus could not be established. Cystoscopic aspects similar to those seen in the initial or minor

  12. Probiotics, dendritic cells and bladder cancer.

    2012-06-01

    What's known on the subject? and What does the study add? The suppressor effect of probiotics on superficial bladder cancer is an observed phenomenon but the specific mechanism is poorly understood. The evidence strongly suggests natural killer (NK) cells are the anti-tumour effector cells involved and NK cell activity correlates with the observed anti-tumour effect in mice. It is also known that dendritic cells (DC) cells are responsible for the recruitment and mobilization of NK cells so therefore it may be inferred that DC cells are most likely to be the interphase point at which probiotics act. In support of this, purification of NK cells was associated with a decrease in NK cells activity. The current use of intravesical bacille Calmette-Guérin in the management of superficial bladder cancer is based on the effect of a localised immune response. In the same way, understanding the mechanism of action of probiotics and the role of DC may potentially offer another avenue via which the immune system may be manipulated to resist bladder cancer. Probiotic foods have been available in the UK since 1996 with the arrival of the fermented milk drink (Yakult) from Japan. The presence of live bacterial ingredients (usually lactobacilli species) may confer health benefits when present in sufficient numbers. The role of probiotics in colo-rectal cancer may be related in part to the suppression of harmful colonic bacteria but other immune mechanisms are involved. Anti-cancer effects outside the colon were suggested by a Japanese report of altered rates of bladder tumour recurrence after ingestion of a particular probiotic. Dendritic cells play a central role to the general regulation of the immune response that may be modified by probiotics. The addition of probiotics to the diet may confer benefit by altering rates of bladder tumour recurrence and also alter the response to immune mechanisms involved with the application of intravesical treatments (bacille Calmette

    Full Text Available The dysfunction of the catheter in peritoneal dialysis (PD is a frequent compli-cation. However, perforation of organs are rare, particularly that of the urinary bladder. This re-quires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur.

    2005-10-01

    Full Text Available Abstract Background There is a popular belief that out-of-home eating outlets, which typically serve energy dense food, may be more commonly found in more deprived areas and that this may contribute to higher rates of obesity and related diseases in such areas. Methods We obtained a list of all 1301 out-of-home eating outlets in Glasgow, UK, in 2003 and mapped these at unit postcode level. We categorised them into quintiles of area deprivation using the 2004 Scottish Index of Multiple Deprivation and computed mean density of types of outlet (restaurants, fast food restaurants, cafes and takeaways, and all types combined, per 1000 population. We also estimated odds ratios for the presence of any outlets in small areas within the quintiles. Results The density of outlets, and the likelihood of having any outlets, was highest in the second most affluent quintile (Q2 and lowest in the second most deprived quintile (Q4. Mean outlets per 1,000 were 4.02 in Q2, 1.20 in Q4 and 2.03 in Q5. With Q2 as the reference, Odds Ratios for having any outlets were 0.52 (CI 0.32–0.84 in Q1, 0.50 (CI 0.31 – 0.80 in Q4 and 0.61 (CI 0.38 – 0.98 in Q5. Outlets were located in the City Centre, West End, and along arterial roads. Conclusion In Glasgow those living in poorer areas are not more likely to be exposed to out-of-home eating outlets in their neighbourhoods. Health improvement policies need to be based on empirical evidence about the location of fast food outlets in specific national and local contexts, rather than on popular 'factoids'.

    The ocean plays an important role in modulating the mass balance of the Greenland Ice Sheet by delivering heat to the marine-terminating outlet glaciers surrounding the Greenland coast. The warming and accumulation of Atlantic Water in the subpolar North Atlantic has been suggested to be a potential driver of the glaciers' retreat over the last decades. The shelf regions thus play a critical role for the transport of Atlantic Water towards the glaciers, but also for the transfer of freshwater towards the deep ocean. A key region for the mass balance of the Greenland Ice Sheet is the Northeast Greenland Ice Stream. This large ice stream drains the second-largest basin of the Greenland Ice Sheet and feeds three outlet glaciers. The largest one is Nioghalvfjerdsfjorden (79°N-Glacier) featuring an 80 km long floating ice tongue. Both the ocean circulation on the continental shelf off Northeast Greenland and the circulation in the cavity below the ice tongue are weakly constrained so far. In order to study the relevant processes of glacier-ocean interaction we combine observations and model work. Here we focus on historic and recent hydrographic observations and on the complex bathymetry in the Northeast Greenland shelf region, which is thought to steer the flux of warm Atlantic water onto the continental shelf and into the sub-ice cavity beneath the 79°N-Glacier. We present a new global topography data set, RTopo-2, which includes the most recent surveys on the Northeast Greenland continental shelf and provides a detailed bathymetry for all around Greenland. In addition, RTopo-2 contains ice and bedrock surface topographies for Greenland and Antarctica. Based on the updated ocean bathymetry and a variety of hydrographic observations we show the water mass distribution on the continental shelf off Northeast Greenland. These maps enable us to discuss possible supply pathways of warm modified Atlantic waters on the continental shelf and thus potential ways of heat

    A prospective study was performed to investigate combined treatment with intra-arterial chemotherapy and radiation therapy for bladder preservation in locally invasive bladder cancer. Patients with invasive bladder cancer, stage T2-3N0M0, were included in the study. lntra-arterial chemotherapy was performed with three injections of methotrexate and cisplatin at 3-week intervals. Simultaneously, the patients underwent X-ray irradiation (40 Gy) of the small pelvic space. Where a post-treatment transurethral resection (TUR) biopsy showed no residual tumor, the tumor site was irradiated by a 30 Gy proton beam and the bladder was preserved. Where tumors remained, radical cystectomy was performed. Between 1990 and 1996, 42 patients were treated according to this protocol. Post-treatment TUR biopsy and urine cytology showed no residual tumors in 39 of 42 cases (93%). The bladder was preserved in accordance with the study protocol in 36 cases. A median follow-up of 38 months showed 3-year non-recurrence in 72% of bladder-preserved patients and the rate of bladder preservation was 84%. The nine recurrences included eight cases of superficial bladder recurrence. One cancer death occurred among the bladder-preservation patients, giving 3-year survival and cause-specific survival rates of 84% and 100%, respectively. Although bladder function decreased slightly in compliance, bladder capacity was retained in almost all cases. This regimen is useful for bladder preservation in T2-3 locally invasive bladder cancer. Information from more cases and the results of more long-term observations are needed, as is an evaluation of appropriate subject selection and factors associated with quality of life issues, particularly regarding bladder function.

BWT and UEBW were determined non-invasively with a portative ultrasound device; Bladder Scan BVM 6500 (Verathon Inc., WA, USA at a frequency of 3.7 MHz at functional bladder capacity. These values were compared by gender, and their relation was assessed with age, body mass index (BMI and parity. Results: Mean BWT was 2.0 ± 0.4 mm and UEBW was 44.6 ± 8.3 g at a mean volume of 338.0 ± 82.1 ml. Although higher results were obtained in men at higher bladder volumes, the results did not differ significantly by gender. Correlation analyses revealed statistically significant correlation between UEBW and age (r = 0.32. BWT was negatively correlated with volume (r = -0.50 and bladder surface area (r = -0.57. Also, statistically significant correlations were observed between UEBW and volume (r = 0.36, bladder surface area (r = 0.48 and BWT (r = 0.25. Conclusion: Determined values of BWT and UEBW in healthy population are estimated with portative ultrasound devices, which are future promising, for their convenient, easy, non-invasive, time-efficient hand-held use for screening.

    The use of ice cubes in beverages is common among patrons of food outlets in Malaysia although its safety for human consumption remains unclear. Hence, this study was designed to determine the presence of faecal coliforms and several useful water physicochemical parameters viz. free residual chlorine concentration, turbidity and pH in ice cubes from 30 randomly selected food outlets in Kubang Kerian, Kelantan. Faecal coliforms were found in ice cubes in 16 (53%) food outlets ranging between 1 CFU/100mL to >50 CFU/ 100mL, while in the remaining 14 (47%) food outlets, in samples of tap water as well as in commercially bottled drinking water, faecal coliforms were not detected. The highest faecal coliform counts of >50 CFU/100mL were observed in 3 (10%) food outlets followed by 11-50 CFU/100mL and 1-10 CFU/100mL in 7 (23%) and 6 (20%) food outlets, respectively. All samples recorded low free residual chlorine concentration (food outlets or (2) they may not be the water sources used for making ice cubes.

    2008-11-01

    Full Text Available The objective of this study was to assess the relationship between alcohol availability, as measured by the density of off-premise alcohol outlets, and alcohol consumption in Los Angeles county and southern Louisiana, USA. Consumption information was collected through a telephone survey of 2,881 households in Los Angeles county and pre-Katrina southern Louisiana, nested within 220 census tracts. Respondents’ addresses were geo-coded and both neighbourhood (census tracts and buffers of varying sizes and individual (network distance to the closest alcohol outlet estimates of off-sale alcohol outlet density were computed. Alcohol outlet density was not associated with the percentage of people who were drinkers in either site. Alcohol outlet density was associated with the quantity of consumption among drinkers in Louisiana but not in Los Angeles. Outlet density within a one-mile buffer of the respondent’s home was more strongly associated with alcohol consumption than outlet density in the respondent’s census tract. The conclusion is that the relationship between neighbourhood alcohol outlet density and alcohol consumption is complex and may vary due to differences in neighbourhood design and travel patterns.

    Spinal cord ischemia is a well-known potential complication of endovascular aneurysm repair (EVAR), and it is usually manifested by paraplegia or paraparesis. We describe a case in which spinal cord ischemia after EVAR presented by isolated bladder and rectal incontinence without other neurological deficits. A 63-year-old woman presented with intermittent claudication secondary to an infrarenal abdominal aortic aneurysm (AAA), and a left common iliac artery obstruction, for which she underwent EVAR using an aorto-uniiliac (AUI) device and ilio-femoral artery bypass. On postoperative day 3, she developed urinary and fecal incontinence without signs of paraplegia or paraparesis. Magnetic resonance imaging (MRI) showed a hyper-intense signal in the spinal cord. She received hyperbaric oxygen (HBO) therapy and was discharged after 18 days when her urinary and fecal incontinence were almost resolved. This report suggests that spinal cord ischemia after EVAR for aortoiliac occlusive disease might present as bladder and rectal incontinence without other neurological manifestations. PMID:26943687

  7. Resolving wall loss in Candu outlet feeder pipes

    International Nuclear Information System (INIS)

    The primary circuit carbon steel feeder piping of CANDU reactors with Cr content in the range 0.02-0.04 wt% has been found to show wall thinning at the exit of the fuel channels as a result of a flow accelerated corrosion mechanism. The observed wall thinning correlates well with the coolant velocity in the fuel channels and is dependent on the pHa of the coolant. The pHa is the room temperature pH reading of a heavy water sample measured using a glass electrode calibrated using light water standards. Based on the results of recent low velocity corrosion tests, operation at the low end of the original pHa specification will allow the feeder pipes in existing CANDU reactors to achieve their design life. For reactors under construction and for future CANDU reactors, the feeder pipe material is now specified to have a minimum Cr content of 0.20 wt%, and available information indicates that the presence of Cr at these concentrations will eliminate concerns regarding flow accelerated corrosion of CANDU outlet feeder piping.

  8. [Neurological Signs and Symptoms of True Neurogenic Thoracic Outlet Syndrome].

    2016-05-01

    Thoracic outlet syndrome (TOS) is a well-known disorder, but many aspects of its pathology, including its definition, has been disputed. True neurogenic TOS (TN-TOS) is a rare but well-defined clinical condition. TN-TOS results from the compression of the C8/T1 roots (dominant for the T1 root) or the proximal lower trunk of the brachial plexus by a fibrous band. The band extends from the first rib to either the tip of an elongated C7 transverse process or a rudimentary cervical rib. The most common presenting symptoms of TN-TOS are insidious-onset atrophy and weakness of the intrinsic hand muscles, predominantly in the thenar eminence and radial digit flexors. Nerve conduction studies demonstrate pathognomonic findings: severely attenuated compound muscle action potential of the abductor pollicis brevis muscle, and usually, loss of the sensory nerve action potential of the medial antebrachial cutaneous nerve. Numbness and sensory loss are typically observed, mainly in the medial forearm, although they are usually mild, and may be absent in some patients. Severe pain or paresthesia proximal to the elbow is not observed. The classical concept of TOS underlie nonspecific neurogenic TOS. It has been primarily diagnosed using provocative maneuvers. However, there is controversy regarding its pathological conceptualization and existence, as objective evidence of the disease is still lacking. PMID:27156505

  9. Simultaneous tracing of 131-I-hippuran and 197-Hg-chlormerodrin uptake curve in obstructive uropathy

    International Nuclear Information System (INIS)

    With a double isotope technique, simultaneous tracing of 131I-hippuran renogram and 197Hg-chlormerodrin uptake curve are routinely carried out. This procedure not only saved the time required for each tracing, but served to quantitatively evaluate renograms in patients with urinary tract abnormalities. The dose of 197Hg used was more than 5 times larger than that of 131I, since the rate of 131I counts in the 197Hg window was experimentally confirmed to be less than 10 per cent at these doses. The changes of urine flow from the pelvis to the bladder caused by acute ureteral obstruction, voiding in the presence of vesicoureteral reflux, and bladder filling, altered the hippuran renogram pattern. These alterations were characterized by a delay in excretory phase, a sudden elevation of slow down curve, and a prolongation or renal transit time. However, the chlormerodrin uptake curves were not affected by these changes in urine flow. Bladder emptying by catheterization in patients with large amounts of residual urine produced a renogram pattern with shortened transit time, and revealed that the T 1/2 value of the slow component of blood disappearance curve was also decreased. However, changes of the chlormerodrin uptake curve and its blood disappearance curve after bladder emptying were negligible. Problems of computer assessment of 131I-hippuran renograms in patients with urinary tract abnormalities were investigated, and the advantages of simultaneous tracing of 197Hg-chlormerodrin uptake curve were emphasized.

  10. Obstructive sleep apnea in chronic obstructive pulmonary disease patients.

    LENUS (Irish Health Repository)

    Lee, Ruth

    2012-02-01

    PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome. RECENT FINDINGS: The severity of obstructive ventilatory impairment and hyperinflation, especially the inspiratory capacity to total lung capacity (TLC) ratio, correlates with the severity of sleep-related breathing disturbances. Early treatment with continuous positive airway pressure (CPAP) improves survival, reduces hospitalization and pulmonary hypertension, and also reduces hypoxemia. Evidence of systemic inflammation and oxidative stress in COPD and sleep apnea provides insight into potential interactions between both disorders that may predispose to cardiovascular disease. Long-term outcome studies of overlap patients currently underway should provide further evidence of the clinical significance of the overlap syndrome. SUMMARY: Studies of overlap syndrome patients at a clinical, physiological and molecular level should provide insight into disease mechanisms and consequences of COPD and sleep apnea, in addition to identifying potential relationships with cardiovascular disease.

    2012-01-01

    Regarding the impact of visceral dysfunction on quality of life, bowel and bladder management is a very important problem. The management of the patient with neurological bladder is often a source of uncertainty for both patients and healthcare personnel. Since the need of specialized training is growing, two CME e-learning courses have been developed to provide physicians and nurses competencies for the enhancement of the daily life of the patients. The present study aims at evaluating courses attendance and outcomes. Attendance data confirm the interest for both courses. The results document a pretty good objective and subjective effectiveness of the e-learning courses but low attitude to exploit he support of an asynchronous tutor. The analysis of test results gives some hints for eventual quality improvement of the courses themselves. PMID:22874390

    Full Text Available Carcinoma gall bladder is a very aggressive disease with poor outcomes. Despite achievements in the field of advanced imaging techniques, there is a very high mortality rate of the disease Cancer is the second most common disease in India responsible for maximum mortality with about 0.3 million deaths per year. The magnitude of cancer problem in the Indian Sub-continent (sheer numbers is increasing due to poor to moderate living standards and inadequate medical facilities. Women are more commonly affected than men. The peak incidence occurs in people in their 60s, but the disease age range is from 29 to 90 years of age and there is great geographic and ethnic variation. Carcinoma gall bladder, a disease of old age, is now found in the younger age group and presents with greater ferocity.

    A scheme of therapy of radiation cystitis is suggested. It was developed on the basis of evaluation of literature and clinical data of 205 patients with radiation injury of the urinary bladder. The method is based on general and local therapy of damaged tissues by antiinflammatory drugs, anesthetics and stimulators of reparative regeneration. Severe ulcerative and incrustation cystites, refractory to conservative therapy, were treated by surgery, using antiseptics and reparation stimulators before, during and after operation. As a result, there were hardly any complications after reconstruction of the bladder with intestinal and peritoneal tissues. 104 patients (96.1%) were cured completely and ability to work was restored in 70 patients (76.9%).

    Full Text Available Skeletal metastasis as a primary presentation of gall bladder carcinoma is rare. A 50-year-old lady presented with neck pain and weakness in her right upper limb of 3 months duration. Clinical and imaging work-up suggested locally advanced gall bladder carcinoma with metastasis to cervical vertebra and sternum. Only one case till date has been reported where the patient presented with neurological symptoms due to pathological fracture secondary to metastasis from an occult gall bladder carcinoma. Although rare, an occult gall bladder cancer may present with neurological symptoms due to pathological fracture of spine secondary to metastasis. We present a brief review of literature of patients who presented with skeletal metastases in clinically silent gall bladder malignancy. Palliative care issues in advanced gall bladder carcinoma have also been discussed.

    Dodge, F. T.; Kana, D. D.

    A system identification methodology was used to examine the dynamics of liquid sloshing in the upright and inverted bladdered hydrazine tanks of the Tracking and Data Relay Satellite, (TDRS) and to evaluate the effects of bladder stiffness on the sloshing parameters. Mechanical models of the two systems were developed using the numerical values derived from static stability tests and from slosh frequency response tests of a full-size model tank fitted with a prototype bladder. For the upright tank (liquid below the bladder) a modified conventional pendulum was used. In the inverted tank (liquid above the bladder) where sloshing is unconventional due to the highly nonsymmetrical orientation of the liquid held by the bladder, a mechanical model using an inverted pendulum which is able to undergo small oscillations as well as large reorientations was necessary. Both thrusting and low-gravity conditions are considered.

  20. Surgical management of the neurogenic bladder and bowel

    Mingin Gerald C.

    2003-01-01

    Full Text Available Spina bifida and myelodysplasia are associated with neurogenic abnormalities of the bladder and bowel function. All children with myelodysplasia require an evaluation of their urinary tract with ultrasound and urodynamics to confirm normal bladder and kidney function. Patients with anatomical and functional abnormalities require treatment, the mainstay being intermittent catheterization and anticholinergic medication. The treatment goals for patients with a neurogenic bladder are the preservation of the upper urinary tract, bladder and bowel continence, independence, autonomy, and facilitation of self-esteem. A minority of children will not respond to conservative therapy and will ultimately require surgical intervention. This review will discuss the surgical options for bladder augmentation, bladder neck reconstruction and closure, as well as the methods for the creation of continent catheterizable stomas. The timing, indications, and description for each procedure will be addressed. Finally, the antegrade continence enema procedure will be described for the management of refractory fecal incontinence.

    Full Text Available Objective: to assess the results of surgical treatment of patients with the intestinal urinary bladder, to characterize its early and late postoperative complications, and to develop their correction tactics.  Subjects and methods. The results of treatment in 198 patients who had undergone ileocystoplasty were analyzed.  Results. The developed diagnostic approach and the determined examination periods could reduce the number of late postoperative complications of ileocystoplasty: acute and chronic pyelonephritis from 19.4 to 7.6%, urolithiasis from 17.2 to 1.9%, bladder dysfunction from 25.8 to 7.6%, and metabolic acidosis from 4.3 to 1.9%, and prevent the development of ureterovesical anastomosis stricture.  Conclusion. Radical cystectomy with the ileoplasty using an isolated segment of the ileum in patients with invasive urinary bladder carcinoma has been the operation of choice no longer; it has become an essential surgical adjunct. This method permits overall 5-year survival to be achieved in 69.7% of patients.  

  2. Routine activities and alcohol use: constraints on outlet utilization.

    1995-02-01

    Studies of consumers' use of alcohol beverage outlets have provided a basis for understanding drinking behaviors in different drinking environments. These studies have shown that drinking environments are related to both demographic and drinking pattern measures. Absent from these studies has been a theoretical basis on which to make predictions regarding drinking patterns and choices of drinking environments under the various social, economic, and environmental constraints typically confronting alcohol consumers. This study presents one such theoretical approach. The approach assumes that, in the context of individual preferences for alcohol, drinking choices are constrained by consumers' economic and time-energy budgets for consumption. All other things being equal, it is suggested that greater budgets for consumption will be related to greater alcohol use, quality of beverages purchased, amenity values of purchase locations, or all three. Because on-premise drinking entails greater economic costs, greater drinking levels will be related to lower utilization of on-premise establishments. The predictions of this approach were tested using data obtained from telephone surveys of consumers conducted in 1990 and 1991. The results showed that controlling for income, variables related to greater time-energy budgets for consumption (i.e., marital status and household composition) were related to greater consumption levels and greater utilization of on-premise establishments. Controlling for demographic measures, greater income was related to greater utilization of restaurants and increased beverage quality. Controlling for all other measures, frequencies of consumption were inversely related to consumption at on-premise establishments, reflecting the expected moderation in costs for heavier consumers on a limited alcohol budget.

  16. Bladder Bulge: Unifying Old and New Sonographic Bladder Wall Abnormalities in Ureterolithiasis

    Directory of Open Access Journals (Sweden)

    Scott Bomann

    2012-12-01

    Full Text Available As long as CT remains the first line imaging modality in suspected ureterolithiasis, emergency physicians will continue to perform the majority of renal colic ultrasound studies in a search for hydronephrosis. Hydronephrosis, however, is not always present and emergency physicians may not find it as useful as would be expected. Through this case series of seven patients, we present what we believe to be commonly present and easily acquired sonographic bladder wall findings in ureterolithiasis. These abnormalities are not routinely taught in emergency ultrasound and have not been reported in the emergency medicine literature. One variant, in fact, may be a novel finding unto itself. Due to their similar appearance, we propose to unify these findings under the name “bladder bulge.” This sign can be seen on axial views as an inward bulging or focal thickening of the bladder wall on the affected side, at the uretovesical junction.

  17. Chronic Intestinal Pseudo-Obstruction.

    Science.gov (United States)

    Panganamamula, Kashyap V; Parkman, Henry P

    2005-02-01

    Chronic intestinal pseudo-obstruction (CIP) is a gastrointestinal motility disorder characterized by chronic symptoms and signs of bowel obstruction in the absence of a fixed, lumen-occluding lesion. Radiographic findings consist of dilated bowel with air-fluid levels. Pseudo-obstruction is an uncommon condition and can result from primary or secondary causes. The management is primarily focused on symptom control and nutritional support to prevent weight loss and malnutrition. The principles of management of patients with CIP involve 1) establishing a correct clinical diagnosis and excluding mechanical obstruction; 2) differentiating between idiopathic and secondary forms; 3) performing a symptomatic and physiologic assessment of the parts of the gastrointestinal (GI) tract involved by manometric and whole gut transit scintigraphic studies; 4) careful assessment of nutritional status of the patient; and 5) developing a therapeutic plan addressing the patient's symptoms and nutritional status. Treatment of CIP includes frequent small meals with a low-fat, low-fiber diet, liquid nutritional supplements may be needed; prokinetic agents such as metoclopramide may help to reduce upper GI symptoms. Trials of drugs such as erythromycin, domperidone, cisapride, and tegaserod may be considered if there is no response. Subcutaneous octreotide may be helpful to improve small bowel dysmotility especially in patients with scleroderma. In patients with symptoms suggestive of bacterial overgrowth, courses of antibiotics such as metronidazole, ciprofloxacin, and doxycycline may be needed. Nutritional assessment and support is an important aspect of management. Enteral nutrition is usually preferred. In carefully selected patients, feeding jejunostomy with or without decompression gastrostomy may be tried. Long term parenteral nutrition should be reserved for patients who can not tolerate enteral nutrition. Complications associated with total parenteral nutrition include

    Full Text Available Aim: To investigate whether risk factors for overactive bladder (OAB in women are associated with symptom severity and to assess the impact of symptom severity on the quality of life. Material and Method: Symptoms of 100 female patients (aged, 47.70 ± 12.34 years who were diagnosed with OAB were assessed using the Boyarsky symptom score (BSS. Data for age, educational status, body mass index (BMI, chronic disease, vaginal deliveries, constipation, smoking, consumption of alcohol, tea, coffee, or carbonated drinks and diets involving spicy food were recorded. Subcategories for each factor regarding quantity were established. The findings were statistically correlated with the BSS and with each urinary symptom individually. Each patient%u2019s quality-of-life (QoL scores were correlated with the severity of each symptom and the total, obstructive and irritative BSS. Results: Urgency was related with BMI, spicy food, vaginal deliveries, menopause, and advanced age. Nocturia had a relation with menopause and advanced age. Total BSS was significantly correlated with coffee consumption. Irritative BSS was correlated with menopause and advanced age and obstructive BSS was correlated with constipation. Total and irritative BSS were both positively correlated with the QoL score. Discusion: Risk factors can affect the severity of symptoms and these factors should be considered when planning therapy.

    This paper describes our method for producing a rat model with an isolated bladder in situ in which the bladder makes no contact with urine. First, the right kidney was removed, then an external catheter was placed in the right ureter for bladder infusions, and next the left ureter was anatomosed...... to the proximal part of the descending colon. The animals were treated with antibiotics, and saline was infused daily into the bladder in order to prevent atrophy. This in situ model is considered to be useful in studies investigating the influence of specific compounds, such as carcinogens, on the...

    Full Text Available Bladder cancer is the seventh most common cancer in men in the world, it is the second most seen cancer after lung cancer and the first in urogenital tumours in Turkey. Many molecular epidemiologic studies have been reported to investigate the associations between the MTHFR C677T and A1298C polymorphisms and bladder cancer risk. In this report, a family with transitional bladder cancer have also MTHFR A1298C heterozygosity which supports the association between MTHFR variants and bladder cancer. This %uFB01nding should be further validated by prospective and larger studies with more diverse ethnic groups.

  6. Bladder metastases of appendiceal mucinous adenocarcinoma: a case presentation

    International Nuclear Information System (INIS)

    Appendiceal adenocarcinoma is rare with a frequency of 0.08% of all surgically removed appendices. Few cases of appendiceal carcinoma infiltrating the bladder wall for spatial contiguity have been documented. A case is reported of a 45-years old woman with mucinous cystadenocarcinoma of the appendix with bladder metastasis. Although ultrasonography and voided urinary cytology were negative, abdomen computed tomography (CT) scan and cystoscopy and subsequent pathological examination revealed a mass exclusively located in the anterior wall of the bladder. Histopathology of the transurethral bladder resection revealed a bladder adenocarcinoma [6 cm (at the maximum diameter) × 2,5 cm; approximate weight: 10 gr] with focal mucinous aspects penetrating the muscle and perivisceral fat. Laparotomy evidenced the presence of a solid mass of the appendix (2,5 cm × 3 cm × 2 cm) extending to the loco-regional lymph nodes. Appendectomy and right hemicolectomy, linfoadenectomy and partial cystectomy were performed. The subsequent pathological examination revealed a mucinous cystadenocarcinoma of the appendix with metastatic cells colonising the anterior bladder wall and several colic lymph nodes. The rarity of the appendiceal carcinoma invading the urinary bladder and its usual involvement of nearest organs and the posterior bladder wall, led us to describe this case which demonstrates the ability of the appendiceal cancer to metastasize different regions of urinary bladder

    Full Text Available In the urinary tract, foreign body is most commonly found in the urinary bladder. But it is anatomically very difficult for a man to self-insert a long object into the urinary bladder. Here we report a case of a 49-year-old Japanese man who has inserted a 140-cm vinyl tube in the bladder for masturbation. He could not retrieve it, and the bladder foreign body remained in this position for about two years. He was referred to our hospital and open surgery was performed.

    1999-11-01

    We report the case of a 52-year-old patient with spina bifida, neurologic bladder, and a history of recurrent urinary tract infections (UTIs) in whom a bladder cancer was incidentally discovered. Cytology, cystoscopy, and cystography showed nonspecific, extensive inflammatory lesions. Cystography demonstrated a complex of diverticulae and cellules. Pathologic examination of a diverticulectomy specimen revealed a grade III pT3b transitional and squamous cell carcinoma. Because of the similar disease causation (recurrent UTIs, stones, and indwelling catheterization), we suggest extension of the guidelines proposed for patients with spinal cord injuries (ie, annual serial bladder biopsies) to patients with nontraumatic neurogenic bladder.

  9. Gender differences in bladder control: from babies to elderly.

    In both sexes, there are anatomical and behavioral differences in dealing with bladder control, as well as voiding and incontinence. Despite intensive research within the last decades, the differences in physiology and pathophysiology as well as gender differences of bladder control and continence are still poorly understood and further research is highly needed. In babies, gender difference seems to be most likely caused by a difference in maturity rate of the bladder. After gaining bladder control, behavior starts to be influenced by socialization. During preschool and school, children experience a negative perception of school toilets. Especially girls crouch over the toilet seat and train to empty the bladder without relaxation of the pelvic floor. This posture may lead to bladder dysfunction. Often adult women continue this bad habit and bladder dysfunction may consolidate. From the fourth decade in both sexes lower urinary tract symptoms start to develop. However, men and women handle the problem variedly showing gender differences in coping strategies with better coping mechanisms in women. In general, gender difference in help seeking and receiving treatment increases with younger age. In elderly, urinary incontinence is only associated with a higher mortality in men, and elderly men seek more often professional help. Aim of the review is to provide an insight into gender differences of bladder control and bladder dysfunction. PMID:23881351

    Objectives. The objectives of this study were to examine the spatial accessibility to alcohol outlets in Quebec and to assess the association between neighborhood level characteristics and availability of alcohol outlets. Methods. The Tobit Model was used to assess the association between neighborhood level characteristics and the availability of alcohol outlets within 500, 1000, 2000, and 3000 metres, respectively. Results. Alcohol outlets were found to be most available in the two largest metropolitan areas of the province of Quebec (Montréal and Québec City). Within 1000 metres, alcohol outlets are more available in neighbourhoods with the following characteristics: highest concentration of men, least materially deprived highest concentration of persons aged 20 years or more, and location either in a metropolitan area or in a small town. Finally, the number of bars with video lottery terminals increases with the level of social and material deprivation. Conclusion. In Québec, there is no rule governing the location of alcohol outlets. Thus, there is an abundant literature indicating that the regulation of alcohol outlet density could be an effective means of controlling risk attributable to alcohol consumption. PMID:25810946

    Full Text Available Abstract Background Food prepared away from home has become increasingly popular to U.S. families, and may contribute to obesity. Sales have been dominated by fast food outlets, where meals are purchased for dining away from home or in the home. Although national chain affiliated fast-food outlets are considered the main source for fast food, fast foods are increasingly available in convenience stores and supermarkets/grocery stores. In rural areas, these nontraditional fast-food outlets may provide most of the opportunities for procurement of fast foods. Methods Using all traditional and nontraditio nal fast-food outlets identified in six counties in rural Texas, the type and number of regular and healthiermenu options were surveyed using on-site observation in all food venues that were primarily fast food, supermarket/grocery store, and convenience store and compared with 2005 Dietary Guidelines. Results Traditional fast-food outlets represented 84 (41% of the 205 opportunities for procurement of fast food; 109 (53.2% were convenience stores and 12 (5.8% supermarkets/grocery stores. Although a s imilar variety of regular breakfast and lunch/dinner entrées were available in traditional fast-food outlets and convenience stores, the variety of healthier breakfast and lunch/dinner entrées was significantly greater in fast food outlets. Compared with convenience stores, supermarkets/grocery stores provided a greater variety of regular and healthier entrées and lunch/dinner side dishes. Conclusion Convenience stores and supermarkets/grocery stores more than double the potential access to fast foods in this rural area than traditional fast-food outlets alone; however, traditional fast food outlets offer greater opportunity for healthier fast food options than convenience stores. A complete picture of fast food environment and the availability of healthier fast food options are essential to understand environmental influences on diet and health

    Bladder sensation is mediated by lumbosacral dorsal root ganglion neurons and is essential for normal voiding and nociception. Numerous electrophysiological, structural and molecular changes occur in these neurons following inflammation. Defining which neurons undergo these changes is critical for understanding the mechanism underlying bladder pain and dysfunction. Our first aim was to define the chemical classes of bladder sensory neurons that express receptors for the endogenous modulators ...
