Giant colonic diverticulum is a rare entity first described in 1946 by Bonvin and Bonte. It may be congenital or acquired and the average age of presentation is 65. There are less than 150 reported cases in the literature. A large abdominal mass was detected during a routine physical examination in an 82-year-old man. CT scan showed a large air-filled mass, barium enema showed multiple sigmoid diverticula, but no communication with the mass was found. A diagnosis of giant sigmoid diverticulum was made, elective sigmoidectomy and resection of the diverticulum was performed with no complications. The clinical picture may be different, varying from asymptomatic to acute abdomen, intestinal perforation or fistula. It can be diagnosed with abdominal X-ray, CT scan, barium enema or MRI, but colonoscopy is not effective. There are two accepted theories of the pathophysiology of this entity: first, a congenital origin and second, that inflammatory diverticula are caused by a perforation with a ball-valve that allows gas to enter, but not to leave the cyst, thus, enlarging the false diverticulum, and progressively destroying the bowel layers, causing secondary fibrosis. Elective treatment is a segmental resection of the affected colon with the diverticulum and in cases of acute abdomen two-stage bowel resection is preferred.

Perforated Meckel’s Diverticulum Lithiasis: An Unusual Cause of Peritonitis

Directory of Open Access Journals (Sweden)

Umasankar Mathuram Thiyagarajan

2013-01-01

Full Text Available Meckel’s diverticulum is the commonest congenital malformation of gastrointestinal tract and represents a persistent remnant of the omphalomesenteric duct. Although it mostly remains silent, it can present as bleeding, perforation, intestinal obstruction, intussusception, and tumours. These complications, especially bleeding, tend to be more common in the paediatric group and intestinal obstruction in adults. Stone formation (lithiasis in Meckel’s diverticulum is rare. We report a case of Meckel’s diverticulum lithiasis which presented as an acute abdomen in an otherwise healthy individual. The patient underwent an exploratory laparotomy which revealed a perforated Meckel’s diverticulum with lithiasis; a segmental resection with end-to-end anastomosis of small bowel was performed. Patient recovery was delayed due to pneumonia, discharged on day 20 with no further complications at 6 months following surgery.

Encountering Meckel's diverticulum in emergency surgery for ascaridial intestinal obstruction

2010-06-01

Full Text Available Abstract Background Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. In children with intestinal ascariasis, the diverticulum remains asymptomatic or rarely the Ascaris lumbricoides may lead to its complications in the presence of massive intestinal roundworm load. Given that preoperative diagnosis is seldom carried out, when Meckel's diverticulum is found at laparotomy for obstructive intestinal complications of roundworm, the diverticulum should be removed as complications may occur at any time. The aim of this study was to describe the findings of concomitant presence of Meckel's diverticulum who had surgical intervention in symptomatic intestinal ascariasis in children. Methods A retrospective case review study of 14 children who had surgical intervention for symptomatic intestinal ascariasis having the presence of concomitant Meckel's diverticulum was done. The study was done at SMHS Hospital Srinagar, Kashmir. Results A total of the 14 children who had ascaridial intestinal obstruction with concomitant presence of Meckel's diverticulum were studied. Age of children ranged from 4-12 years, male:female ratio was 1.8:1. Nine patients had asymptomatic Meckel's diverticulum, whereas 5 patients with symptomatic signs were found in the course of emergency surgery for ascaridial intestinal obstruction. Conclusion Meckel's diverticulum in intestinal ascariasis may pursue silent course or may be accompanied with complications of the diverticulitis, perforation or the gangrene. Incidental finding of the Meckel's diverticulum in the intestinal ascariasis should have removal.

Chan Kim W

2009-02-01

Full Text Available Abstract Introduction Meckel's diverticulum represents a true diverticulum of the ileum containing all three layers of the bowel wall and is found on the wall of the distal ileum, usually about 2 feet from the ileocaecal valve. Although Meckel's diverticulum is a common congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. Patients with perforation of Meckel's diverticulum may present with right iliac fossa pain, which mimics acute appendicitis. Case presentation A 17-year-old man presented with a 3-day history of lower abdominal pain. On examination, the patient had tenderness in his right iliac fossa. A provisional diagnosis of acute appendicitis was made. The patient was taken to theatre for laparoscopy with the option of appendicectomy. The appendix was found to be normal. An inflamed and perforated Meckel's diverticulum was found to be the cause of the abdominal pain. Meckel's diverticulectomy was performed. The patient made an uneventful recovery and was discharged with further follow-up in the outpatient clinic. Conclusion Complications of Meckel's diverticulum can be fatal and early recognition leads to appropriate management. This case report highlights the importance of considering Meckel's diverticulum as a differential diagnosis of acute abdomen in a young patient.

Objective: To investigate the clinical application of electron-beam CT (EBCT) in the diagnosis of congenital cardiovascular diverticula. Methods: Retrospective analysis of 9 patients with congenital cardiovascular diverticula confirmed by operation and pathology was done. Of them, enhanced continuous volume scan was performed on 8 patients and enhanced single slice scan was performed on one patient with an Imatron C-150 scanner. Results: The group of 9 patients included one patient with diverticulum of the left ventricle, 3 patients with diverticulum of the atria and 5 patients with diverticulum of the aorta. EBCT scan and three dimensional reconstruction could demonstrate not only the origin, size, shape, location and adjacent structure of diverticula, but also other important complicated abnormalities such as ventriculoarterial connection disorder, cardiac septal defect, aortic coarctation and even dissection. Conclusion: EBCT is an ideal noninvasive technique in the diagnosis of congenital cardiovascular diverticula. (authors)

2010-05-01

With the increased use of minimally invasive surgery, the urethral diverticulum after anorectal surgery has become an issue. The few cases reported have been managed by surgical excision. We hereby report a case of urethral diverticulum after a laparoscopically-assisted anorectal pull-through (LAARP)procedure with a successful outcome after a period of active surveillance. A full-term boy who displayed a high anorectal malformation (ARM) and a rectoprostatic fistula underwent colostomy on the first day. He also showed associated malformations: bilateral low-grade reflux, horseshoe kidney and thoracic hemivertebrae; however, there were no signs of spinal cord tethering. Antimicrobial prophylaxis was started. At the age of 3 months, he underwent a LAARP with a 3 abdominal-port approach. After complete dissection of the distal bowel, the recto-prostatic fistula was identified and tied with metallic clips. A 10 mm trocar was inserted through the centre of the sphincteric complex, which had been previously identified under laparoscopic view during perineal electrical stimulation. The anorectal pull-through was accomplished without tension. The bladder remained stented for 14 days. On the 18th postoperative day, a voiding cystourethrogram (VCUG) showed a 15 X 5 mm image of the diverticulum at the level of the membranous urethra. After 6 months, a new VCUG showed a normal urethra with neither signs of the diverticulum nor strictures; persistence of grade 2 reflux on the right side and resolution of the reflux on the left. When the boy was one year old his colostomy was closed uneventfully. Six months later he had not come into the emergency since the operation and voided with a normal flow. This report suggests that LAARP is a feasible approach for ARM, although urethral diverticulum is a major concern. It may evolve without complications, and eventually resolve spontaneously. Active surveillance might be an option in selected asymptomatic patients; however a longer

Intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly. IDD can become symptomatic in 20% to 25% of cases when complicated by intestinal obstruction, pancreatitis, or hemorrhage. We report the case of a 21-year-old female presenting with IDD mimicking duodenoduodenal intussusception. We describe the imaging features of IDD on the gadoxetic acid-enhanced magnetic resonance image as well as computed tomography.

Meckel's Diverticulum

Treves, S.T.; Grand, R.

1985-01-01

The primary application of techetium-99m (Tc-99m) pertechnetate scintigraphy of the abdomen is in the diagnosis of Meckel's diverticulum. Some years ago the authors reviewed the records of all patients with Meckel's diverticulum under 2 years of age undergoing operation at the Children's Hospital in Boston between 1951 and 1972. Among 60 infants under 2 years of age, 32 had painless rectal bleeding. Of these 32,56% presented before reaching 1 year of age and the remaining 44% before 2 years of age. Among those symptomatic patients, 91% (29 of 32 patients) had ectopic gastric mucosa in their Meckel's diverticula. The differential diagnosis of rectal bleeding in infants <2 years of age includes Meckel'd diverticulum, anal fissure, volvulus, intussusception, peptic ulcer, and colonic polyp. Of these, only colonic polyp and Meckel's diverticulum usually cause painless bleeding. Radiologic studied using barium by mouth or by rectum only exceptionally demonstrate Meckel's diverticula, as this contrast material rarely enters the lesion

2012-01-01

Meckel's diverticulum is a common asymptomatic congenital gastrointestinal anomaly,but rarely it can present with hemorrhage.Over the last few years inverted Meckel's diverticulum has been reported in the literature with increasing frequency as an occult source of lower gastrointestinal hemorrhage.Here,we report a case of a 54-year-old male,who was referred for surgical evaluation with persistent anemia and occult blood per rectum after a work up which failed to localize the source over 12 mo,including upper and capsule endoscopy,colonoscopy,enteroclysis,Meckel scan,and tagged nuclear red blood cell scan.An abdominal computed tomography scan showed a possible mid-ileal intussusception and intraluminal mass.During the abdominal exploration,inverted Meckel's diverticulum was diagnosed and resected.We review the literature,discuss the forms in which the disease presents,the diagnostic modalities utilized,pathological findings,and treatment.Although less than 40 cases have been reported in the English literature from 1978 to 2005,19 cases have been reported in the last 6 years alone (2006-2012) due to improved diagnostic modalities.Successful diagnosis and treatment of this disease requires a high index of clinical suspicion,which is becoming increasingly relevant to general gastroenterologists.

Urethral diverticulum in pregnancy

Directory of Open Access Journals (Sweden)

Qiao-Xuan Xie

2015-05-01

Full Text Available Urethral diverticulum is rare in pregnancy. There is no clear guideline on the management of urethral diverticulum in pregnancy, but most cases were managed conservatively. We report a case of urethral diverticulum in a primigravida woman, who presented with anterior vaginal swelling at 14 weeks of gestation. She was managed conservatively and the cyst (approximately 8 cm × 13 cm was aspirated during the early stage of labor. However her labor did not progress during the second stage, which resulted in an emergency cesarean section. She underwent diverticulectomy at 1 month postpartum because of the recurrence of the swelling and persistent discomfort. We believe that her dystocia may have been caused by factors other than the diverticulum. As previously described in literature, we concluded that, even in pregnant women with a large urethral diverticulum, vaginal delivery can still be considered with prior aspiration during the early stage of labor.

A Rare Case of Strangulated Meckel%u2019s Diverticulum in an Incarcerated Ventral Incisional Hernia

Full Text Available Incisional or postoperative hernia, one of the most common surgical procedure in general surgery practice, mostly occurs in the first years following abdominal operations. Incarceration or strangulation is a serious complication of these hernias, and mostly requires emergent surgery. Meckel%u2019s diverticulum, the most frequent congenital anomaly of the gastrointestinal tract, is rarely found within a hernial sac and this unusual condition is called as Littre%u2019s hernia. In addition, preoperative diagnosis of this unusual condition is rather difficult and it is almost always first discovered during operation. A small number of cases of strangulated Meckel%u2019s Diverticulum in an incarcerated ventral incisional hernia have been reported in the literature. Herein, we report a strangulated Meckel%u2019s Diverticulum through a ventral incisional hernia in a 65 year-old woman who presented with clinical signs of intestinal obstruction.

Wadin, K.; Wilbrand, H.

1986-01-01

Two hundred and forty-five temporal bone specimens were examined radiographically. Subsequently the topographic relationship between the jugular fossa and surrounding structures was evaluated in plastic casts of the specimens. Fifty-eight casts showed a high jugular fossa and in 17 a jugular bulb diverticulum was found. A diverticulum is regarded as an anomaly of the high jugular bulb and presumably has a potential for expansion. Most frequently a diverticulum was directed medially into the space between the internal acoustic meatus, the vestibular aqueduct and the posterior cranial fossa. Seven diverticula reached the level of the internal acoustic meatus. Encroachment upon the vestibular aqueduct was seen in 4 casts and both the internal acoustic meatus and the cochlear aqueduct were very close to the diverticulum. A few diverticula were directed postero-laterally close to the facial canal and the stapedius muscle. The investigation was supplemented with a selected clinical material of radiographs of temporal bones with high fossae. The results corresponded to those of the experimental investigation. The jugular bulb diverticulum is a relatively common feature and should be regarded as an anomaly with a potential to give rise to clinical symptoms consequent to its intrusion upon surrounding structures.

Zenker's diverticulum - diagnosis and therapy

Energy Technology Data Exchange (ETDEWEB)

Heindel, W; Raab, M

1987-08-01

Clinical, X-ray and endoscopic follow-up of patients operated on for Zenker's diverticulum (pharyngo-oesophageal diverticulum) via myotomy and diverticulectomy permits conclusions in respect of functional results of this therapeutic concept and the preoperative diagnosis that our study has proved to be necessary. Usually the diagnosis can be made on the basis of the characteristic anamnesis. It is confirmed by means of an oesophagogram, if necessary with a gastrointestinal passage. Besides visualisation of Zenker's diverticulum, attention must be paid especially to associated neuromuscular functional disturbances of the oesophagus. Preoperative endoscopy is necessary in individual cases only. In respect of therapy, it appears mandatory to perform a sufficiently extended (3-5 cm) myotomy of the pars transversa musculi cricopharyngei because of the frequently seen disturbance of coordination of the pharyngo-oesophageal sphincter, besides removing the diverticulum.

Congenital anomalies of the male urogenital tract are common. Some lesions like posterior urethral valve or anterior urethral diverticulum tend to present early in infancy and are often easily diagnosed on conventional contrast voiding cystourethrograms. Other conditions like posterior urethral diverticulum or utricle can be relatively asymptomatic and therefore present late in childhood. We present the spectrum of imaging findings of common and uncommon anomalies involving the male urethra. Since the pediatric radiologist is often the first to make the diagnosis, he or she should be well aware of these conditions. PMID:21431032

Meckel's diverticulum (MD) is the most common congenital abnormality of the gastrointestinal tract that is prevalent in 2–3% of the population. The lifetime risk of complications is estimated at 4%. Small bowel obstruction is the second most common complication of MD. Among the causes of bowel obstruction, axial torsion of MD is the rarest complication. Urgent surgical treatment is needed in cases of small bowel obstruction associated with torsion of MD. Pre-operative diagnosis of MD as a cause of small bowel obstruction is difficult, because the diagnosis can be made only if the diverticulum is delineated at the site of obstruction. We reported a case of axial torsion of MD with necrosis that caused proximal small bowel perforation in a 21 year old male.

We present a consensus view of members of the International Children's Continence Society on the therapeutic intervention in congenital neuropatic bladder and bowel dysfunction in children. Discussions were held by a group of pediatric urologists and gastroenterologists appointed by the board. The following draft review document was open to all the ICCS members via the ICCS web site. Feedback was considered by the core authors and by agreement, amendments were made as necessary. The final document is not a systematic literature review. It includes relevant research when available as well as expert opinion on the current understanding of therapeutic intervention in congenital neuropatic bladder and bowel dysfunction in children. Guidelines on pharmalogical and surgical intervention are presented. First the multiple modalities for intervention that do not involve surgical reconstruction are summarized concerning pharmacological agents, medical devices, and neuromodulation. The non-surgical intervention is promoted before undertaking major surgery. Indicators for non-surgical treatments depend on issues related to intravesical pressure, upper urinary tract status, prevalence of urinary tract infections, and the degree of incontinence. The optimal age for treatment of incontinence is also addressed. This is followed by a survey of specific treatments such as anticholinergics, botulinum-A toxin, antibiotics, and catheters. Neuromodulation of the bladder via intravesical electrical stimulation, sacral nerve stimulation, transcutaneous stimulation, and biofeedback is scrutinized. Then follows surgical intervention, which should be tailored to each individual, based on careful consideration of urodynamic findings, medical history, age, and presence of other disability. Treatments mentioned are: urethral dilation, vesicostomy, bladder, augmentation, fascial sling, artificial urinary sphincters, and bladder neck reconstruction and are summarized with regards to success rates

The first reported pediatric case of Killian-Jamieson diverticulum

Full Text Available Esophageal diverticulum is a rare but important cause of dysphagia in children. We present a case of a two year old female with dysphagia from six months of age. Her symptoms were refractory to acid suppressive and prokinetic therapies. Upper GI revealed an anterior proximal esophageal diverticulum consistent with Killian-Jamieson Diverticulum. This was confirmed with EGD and corrected with right cervical exploration with resection of the diverticulum. There are three types of esophageal diverticula based on location in the esophagus. Killian-Jamieson diverticulum is very rare, with less than 30 cases reported, all in the elderly. This is the first reported pediatric case of Killian-Jamieson diverticulum.

Full Text Available Ureteric diverticulum is a rare urological condition with only 47 cases described in the literature till 2013. A full term female infant presented with a huge cystic lump occupying almost the entire right side of the abdomen at 1 month of age. Ultrasonography and Magnetic Resonance Urography (MRU revealed right sided gross hydronephrosis with pelvis appeared folded onto itself along with left sided mild hydronephrosis. On EC scan, differential function of right sided kidney was 0.9%. With working diagnosis of right sided giant hydronephrosis secondary to pelviureteric junction obstruction, the child was posted for Anderson - Hynes pyeloplasty through right flank incision. On exploration we were surprised to find ureteric diverticula. Excision of ureteric diverticulum with proximal ureterostomy was done. Distal part of ureter was transfixed. Histopathological examination of diverticulum showed presence of fibromuscular wall suggestive of true diverticulum. Since ureterostomy was draining only few drops of clear fluid and on repeat EC scan there was no improvement in function of right kidney, right nephroureterectomy was done after 6 months.

Female urethral diverticulum is a localized out-pouching of the urethra that is becoming increasingly prevalent, but often poses a diagnostic challenge. Traditionally, conventional voiding cystourethrography has been used to make the preoperative diagnosis. With the development of higher-resolution images acquired through ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), the anatomy and various abnormalities of the female urethra can be better elucidated. This article focuses on the imaging features of female urethral diverticulum, with emphasis on diagnostic pearls, particularly using MRI. Female urethral diverticulum can be best identified by their location in the posterolateral urethra and by their communication with the urethral lumen. Improved imaging techniques combined with increased physician awareness of urethral diverticulum will lead to more prompt and accurate diagnosis of this entity, leading to better treatment of affected patients

The purpose of the study was to explore the role of sonography for women with a suspected urethral diverticulum and to evaluate the transperineal ultrasonographic findings of female urethral diverticulum. Eight women (mean age, 44 years) who presented with urethral symptoms and clinically suspected urethral diverticula underwent transperineal ultrasonography; sagittal and coronal images were obtained. Sonography was done with either a 7-5 MHz curved array transducer or 10-5 MHz linear transducer, placed on the perineum at the level of the urethra. Ultrasonograms were assessed for the presence, size, location, shape, echogenicity, and septum. Five patients underwent voiding cystourethrography (VCUG). Results of the sonograms and VCUGs were compared with each other and with surgical findings. Longitudinally, all lesions were located in a middle third of the urethra. In axial plane, 4 diverticula wrapped around 50-100% of the urethra. 3 cases located posteriorly, and 1 case laterally. Seven diverticula contained echogenic debris. Three cases have septa in the diverticulum. The outer margin of the diverticula was smooth in 2 patients and was lobulated in 6 patients. In 3 of 5 cases who underwent VCUG, diverticula were filled with contrast, and appeared to be smaller than those of ultrasonography. In addition, all were single diverticulum in VCUG. Most urethral diverticulum were located in a middle third of the urethra, wrapped around the urethra or round posteriorly. Many cases appear unilocular or multilocular with echogenic debris. Transperineal ultrasonography is easy to operate and accurate for showing urethral diverticulum, and it may be useful for diagnosing this group of women with urethral symptoms and suspected urethral diverticulum. It provides information on the extent and location of the diverticulum, which are important in surgical excision.

Virtual cystoscopy of urinary bladder. A pilot study

1999-01-01

Cystoscopy plays a key role in the diagnosis of the urinary bladder carcinoma. However cystoscopy is invasive, as a limited field of view and lacks an objective scale; moreover it is not indicated in patients with severe urethral stricture or active vesical bleeding. In this study, virtual cystoscopy depicted all the masses > 1 cm, and lesions in a diverticulum with a small opening. Virtual cystoscopy was also very useful in a patient with urethral stricture (ho could not be submitted to conventional cystoscopy) where it showed the lesions before transurethral resection after urethrotomy. The virtual technique could also be complementary to conventional cystoscopy in evaluation of bladder base and anterior bladder neck, as well as post chemotherapy follow-up. Unfortunately virtual cystoscopy does not allow biopsy of suspicious lesions [it

Esophageal epiphrenic diverticulum associated with diffuse esophageal spasm.

2015-01-01

Esophageal diverticulum, a relatively rare condition, has been considered to be associated with motor abnormalities such as conditions that cause a lack of coordination between the distal esophagus and lower esophageal sphincter. We herein report a case of esophageal epiphrenic diverticulum associated with diffuse esophageal spasm. A 73-year-old woman presented with dysphagia and regurgitation. Imaging examinations revealed a right-sided esophageal diverticulum located about 10cm above the esophagogastric junction. High-resolution manometry revealed normal esophageal motility. However, 24-h pH monitoring revealed continuous acidity due to pooling of residue in the diverticulum. An esophageal epiphrenic diverticulum was diagnosed and resected thoracoscopically. Her dysphagia recurred 2 years later. High-resolution manometry revealed diffuse esophageal spasm. The diverticulum in the present case was considered to have been associated with diffuse esophageal spasm. The motility disorder was likely not identified at the first evaluation. In this case, the patient's symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Olson, Doug E.; Donnelly, Lane F.; Kim, Yong-Woo

2009-01-01

Approximately 0.04% of the general population will present with a complication related to Meckel diverticulum. The classic teaching is that symptomatic children with Meckel diverticulum present with painless rectal bleeding and are evaluated with a radionuclide scan. Our subjective experience is that we see children with Meckel diverticulum who present with abdominal pain and are evaluated by CT. We reviewed the findings on CT in children with pathologically proven Meckel diverticulum to identify characteristic patterns of presentation. Databases were searched (2004-2008) for all children who had a pathologic diagnosis of Meckel diverticulum and a CT scan performed prior to surgery. Demographics, pathology, and CT features were reviewed. CT features reviewed included: soft-tissue stranding, abnormal calcifications, bowel obstruction, free air, free peritoneal fluid, cystic mass, intussusception, obvious lead point, location, and whether a normal appendix was identified. The frequency of Meckel diverticulum encountered on CT scans was compared to that found during the same period of time on technetium pertechnetate studies. The review identified 16 subjects (mean age 9.5 years, M:F 9:7). CT findings included: soft-tissue stranding in nine (56%), small-bowel obstruction (SBO) in nine (56%), intussusception in three (19%), free fluid in ten (63%), cystic mass in four (25%), calcification in none (0%), free air in one (6%), and no abnormalities in two (13%). A normal appendix was identified in only five children (31%). There were three basic patterns of presentation of abnormalities: SBO only in five, intussusception with SBO in three, or cystic mass with inflammatory stranding in four (one with SBO). Also, 2.3 times more Meckel diverticulum was encountered on CT than on technetium pertechnetate studies. Meckel diverticulum is currently more commonly encountered in children on CT performed for abdominal pain than on technetium pertechnetate studies. There are three

Killian-Jamieson diverticulum is a outpouching of the lateral cervical esophageal wall adjacent to the insertion of the recurrent laryngeal to the larynx and is much less common in clinical practice than Zenkers Diverticulum. Surgical management of Killian-Jamieson diverticulum requires open transcervical diverticulectomy due to the proximity of the recurrent laryngeal nerve to the base of the pouch. We present a case of a Killian-Jamieson diverticulum associated with a concurrent large type III paraesophageal hernia causing significant solid-food dysphagia, post-prandial regurgitation of solid foods, and chronic cough managed with open transcervical diverticulectomy and laparoscopic paraesophageal hernia repair with Nissen fundoplication.

Most tracheobronchial and parenchymatous congenital abnormalities of the respiratory system are diagnosed in early life. However, some lesions may be initially silent and diagnosed only in adulthood. These cases included congenital abnormalies of the tracheobronchial tract (tracheal and/or bronchial stenosis, bronchogenic cysts, bronchial atresia, oesotracheal fistula, oesobronchial fistula, and tracheal diverticulum), and lung parenchyma itself (pulmonary sequestration, congenital cystic adenomatoïd malformation, lobar emphysema, lobar or lung hypoplasia). To avoid dreadful complications, these rare cases deserve surgical management, and must be known by chest physicians and surgeons. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Neurogenic Bladder

Directory of Open Access Journals (Sweden)

Peter T. Dorsher

2012-01-01

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.

Seven patients with clinically suspected Meckel's diverticulum were examined. The symptoms of Meckel's diverticulum are variable, ranging from mild recurrent or severe acute gastrointestinal bleeding to intestinal obstruction and acute peritonitis. The authors evaluate the diagnostic results and suggest guidelines to choose the most appropriate radiological procedures, according to the clinical pattern: barium meal, enteroclysis and scintigraphy ( 99m TC) in patients with mild bleeding; mesenteric angiography in case of severe bleeding. The possibility of false negatives and positives is then discussed

Zenker's diverticulum is a mucosal lined outpouching of pharynx through Lainert's space that causes dysphagia of the upper digestive tract. Multiples theories try to explain the acquired etiology of this entity, attributing its origin to a disfunction of pharynx-esophageal sphincter. A case of total larynguectomy with hypopharyngeal diverticulum and progressive dysphagia to solid food is presented. We analyze the etiopathogenic mechanisms and the definitive characteristics of this entity. We review mundial literature, being exceptional the fact of finding clinical manifestations in diverticulum of larynguectomized patients.

An acute aortic dissection involved the retroesophageal aortic diverticulum (RAD) and descending thoracic aorta in a patient with right aortic arch. The RAD, which was separated into false and true lumens by an intimal flap-the classic diagnostic sign of aortic dissection-was overlooked on transesophageal echocardiography and computed tomography but was clearly depicted on magnetic resonance imaging (MRI). It was found that MRI can delineate the anatomy of a congenital arch anomaly complicated by great vessels disease

Full Text Available Although colonic diverticulum is a common disease, affecting about 35% of patients above the age of 60, giant sigmoid diverticulum is an uncommon variant of which only relatively few cases have been described in the literature. We report on our experience with a patient affected by giant sigmoid diverticulum who was treated with diverticulectomy. Resection of the diverticulum is a safe surgical procedure, provided that the colon section close to the lesion presents no sign of flogosis or diverticula; in addition, recurrences are not reported after 6-year follow-up.

Duodenal diverticulum is common, but its perforation is a rare complication. Duodenal diverticulum perforation requires prompt treatments because of its high mortality rate. However, an accurate diagnosis is difficult to make due to nonspecific symptoms and signs. It can be misdiagnosed as pancreatitis, cholecystitis, or peptic ulcer. Herein, we report a case of perforated duodenal diverticulum caused by bezoar in a 33-year-old woman whom was diagnosed by abdomen computed tomography and ultrasonography.

Zenker's diverticulum is a pulsion typed pharyngoeosophageal diverticle caused by the herniation of the pharyngeal mucosa, standing beside the posterior pharyngeal wall, through the Killian opening which is known as the weak area between the inferior constructor muscle's oblique fibres and transverse fibres of cricopharyngeal muscle. In patients with Zenker's diverticulum, symptoms such as disfagia, globus in the cervical area, weigh loss, regurgitation, cough, and aspiration. These patients are primarily admitted to the Gastroenterology and Othorhinolaryngology clinics with the complaint of disfagia and the diagnosis of this disease is mostly established late and the treatment is started late because the results of their physical examinations seem normal. Therefore, especially in the patients who have disfagia complaint, pharyngoeosophageal diverticle prediagnosis should be thought and that should be examined by passage graphies with barium and endoscopic methods, if needed. In this article, we presented the 67-year-old Zenker's diverticulum patient in whom we performed open diverticulectomy and posterior cricopharyngeal myotomy, and we specified the important points in choosing the patient and the type of surgery.

Abdominal colic due to ureteric diverticulum with stone formation

Roodhooft, A.M.; Boven, K.; Acker, K.J. van; Gentens, P.

1987-01-01

In a 15-year-old boy right lower abdominal colicky pain was caused by intermittent obstruction of the ureter by stones which had accumulated in a ureteric diverticulum. As was shown by repeated X-rays, each of these stones had moved to the ureter and back to the diverticulum. Ureteric diverticulum mostly remains asymptomatic in children: stone formation and obstruction of the ureter by the stones is one of the instances which may cause symptoms. (orig.)

the rectum still has controversial aspects regarding its origin is congenital or acquired. Recently, alterations of the evacuative dynamic had been associated with the development of the disease. Nevertheless, until the present date, the manometric alterations in patients with diverticulum of the rectum were not studied. OBJECTIVE: The aim of the present study is to demonstrate the results of electromanometric study carried out in a patient with isolated diverticulum of the rectum. CASE REPORT: A man and a woman, 56 and 58 years-old, respectively, were submitted to colonoscopy, barium enema, endorectal ultrasound and magnetic resonance of the pelvis to diagnose and document the presence of diverticulum located in the rectum. The patients were submitted to manometry using catheter with eight-channel perfusion under water at 0.3 ml/min/channel, through pneumatic and hydraulic capillary infusion system. The anorectal manometry showed normally sphincter pressure profile both in rest and squeezes pressure state, and did not find sphincter asymmetries. The anorectal inhibition reflex was present with normal values and the sensibility and rectal complaisance were between the normal limits. The vector volume analysis did not show any significant alterations and it was concluded by normal manometric anorectal study. CONCLUSION: The anorectal manometry study did not demonstrate the existence of pressure disturbances in anorectal sphincter, enhancing the possibility that the rectal diverticulum can be congenital, developing at points where there is major weakness of the rectal wall.

2006-01-01

Objective: assessed the usefulness of virtual cystoscopy performed with multidetector computed tomography (CT) in patients with different urinary bladder pathologies compared to the conventional cystoscopy.Materials and methods: eighteen patients with different bladder pathologies, which consisted of 11 tumors, 3 diverticula, 2 trabecular changes and 2 stones, were assessed with conventional cystoscopy and virtual CT cystoscopy. The results of virtual CT cystoscopy were compared with the findings of conventional cystoscopy. We determined the detection rate and positive predictive value of CT imaging based virtual cystoscopy in the diagnosis of urinary bladder lesions. Results: CT scanning was well tolerated by all patients, and no complications occurred. Images in 16 (88%) of the 18 virtual cystoscopic examinations were either of excellent or good quality. All tumors except one, 2 trabecular changes and 2 stones were characterized with similar findings in the both of methods. The masses ranged from 0.4 to 7.0 cm in diameter. While conventional cystoscopy could not evaluate interior part of the diverticulum, virtual CT cystoscopy could demonstrate clearly within it. There were no false-positive findings in our series. Conclusion: virtual CT cystoscopy is a promising technique to be used in the detection of bladder lesions. It should be considered especially at the evaluation of bladder diverticula. In the future, it may be possible or even advantageous to incorporate into the imaging algorithm for evaluation of bladder lesion. (author)

Laparoscopic Meckel's diverticulumectomy following positive Meckel's diverticulum scan

Mansberg, R.; Roberts, J.M.; Tan, B.

2002-01-01

Full text: Laparoscopic or 'keyhole' surgery is increasingly performed to reduce morbidity and length of hospital admissions. Laparoscopic resection of a Meckel's Diverticulum has rarely been performed as the diagnosis is only rarely made prior to surgery and most patients proceed to exploratory laparotomy. A positive Meckel's scan and subsequent laparoscopic Meckel's Diverticulumectomy is presented. A 26-year-old male tourist presented with GIT bleeding following acute alcohol ingestion. He had previously been unsuccessfully investigated in England for GIT bleeding. Following a negative gastroscopy a Meckel's Diverticulum scan was performed. The study clearly demonstrated ectopic gastrin secreting mucosa in the right iliac fossa .The following day the patient went to theatre and at laparoscopy the Meckel's diverticulum was identified and resected. Histological examination confirmed the diagnosis of a Meckel's Diverticulum. The patient returned to England 2 days later. This case illustrates how a scintigraphic diagnosis can avoid exploratory surgery and result in less invasive laparoscopic surgery.

The presence of gastric ectopic mucosa in Meckel's diverticulum is associated with a higher risk of development of complications. The aim of the present study was to investigate which demographic/clinical parameters predict the presence of gastric heterotopia in Meckel's diverticulum. This was a retrospective cohort study conducted in a single institution (University Hospital Ostrava, Czech republic). All children who underwent laparoscopic/open resection of Meckel's diverticulum within a 20-year study period were included in the study. In total, 88 pediatric patients underwent analysis. The mean age of the children was 4.6 ± 4.73 years; the male-female ratio was approximately 2:1. There were 50 (56.8%) patients with asymptomatic Meckel's diverticulum in our study group. Laparoscopic resection was performed in 24 (27.3%) patients; segmental bowel resection through laparotomy was performed in 13 (14.8%) patients. Gastric heterotopia was found in 39 (44.3%) patients; resection margins of all patients were clear of gastric heterotopia. No correlation was found between the presence of gastric heterotopia and the following parameters: age, gender, maternal age, prematurity, low birth weight, perinatal asphyxia, distance from Bauhin's valve and length of Meckel's diverticulum. The width of the diverticulum base was significantly higher in patients with gastric heterotopia (2.1 ± 0.57 vs. 1.2 ± 0.41 cm; p < 0.001). According to the study outcomes, the width of the diverticulum base seems to be a significant predictive factor associated with the presence of gastric heterotopia in Meckel's diverticulum. The laparoscopic/open resection of asymptomatic MD with a wide base should therefore be recommended.

Surgical treatment is often recommended for urethral diverticulum or calculus, but treatment for an impacted urethral calculus complicated by a stone-containing diverticulum is challenging. Materials and Methods An 82-year-old man had the persistence of LUTS despite having undergone transurethral resection of prostate for BPH. Regardless of treatment with broad spectrum antibiotics and an α-blocker, LUTS and post-void residual urine volume (100 mL did not improve although repeated urinalysis showed reduction of WBCs from 100 to 10 per high power field. Further radiology revealed multiple urethral calculi and the stone configuration suggested the existence of a diverticulum.

Results The operative time was 30 minutes and the stones were cleanly removed. The patient was discharged after 48 hours with no immediate complications and free of LUTS during a 2 years follow-up. Conclusions When the diverticulum is the result of a dilatation behind a calculus, removal of the calculus is all that is necessary. Compared with open surgery, ultrasound lithotripsy is less invasive with little harm to urethral mucosa; and more efficient as it absorbs stone fragments while crushing stones.

Full Text Available Meckel′s diverticulum, the most common congenital abnormality of the small intestine, may be associated to heterotopic pancreas, often diagnosed incidentally on histopathological examination. Intussusception affects infants between the ages of 5 and 9 months, but it may also occur in older children, teenagers and adults, and in some cases can be derived by a Meckel′s diverticulum resulting in acute abdomen. We analyse the management and the recent literature on similar cases, describing diagnostic options. In May 2013, a 7-year-old girl admitted to our hospital with recurrent gastrointestinal bleeding, was discovered to have an ileoileal intussusception with a leading Meckel′s diverticulum with heterotopic pancreatic tissue. This association is rare evidence in children and its proper management can be controversial, in particular from a diagnostic point of view. In such cases, preoperative radiological diagnosis can be only suspected in the presence of suggestive signs, more often depicted by ultrasound or computed tomography scan. During laparotomy an accurate exploration of all ileum is recommended, for the possibility to find others heterotopic segments.

Zenker's Diverticulum: Diagnostic Approach and Surgical Management

Full Text Available Zenker's diverticulum (ZD, also known as cricopharyngeal, pharyngoesophageal or hypopharyngeal diverticulum, is a rare condition characterized by an acquired outpouching of the mucosal and submucosal layers originating from the pharyngoesophageal junction. This false and pulsion diverticulum occurs dorsally at the pharyngoesophageal wall between the inferior pharyngeal constrictor and the cricopharyngeus muscle. The pathophysiology of ZD involves altered compliance of the cricopharyngeus muscle and raised intrabolus pressure. Decreased compliance of the upper esophageal sphincter and failure to open completely for effective bolus clearance both lead to an increase in the hypopharyngeal pressure gradient. Different open surgical techniques and transoral endoscopic approaches have been described for the management of ZD, although there is no consensus about the best option. We report the case of a 61-year-old patient with a 7-year history of dysphagia and odynophagia for solid food, which after 2 months progressed to dysphagia for liquids and after 4 months to regurgitation 2-6 h after meals. The patient experienced a 12-kg weight loss. Diagnosis was established by esophagogram, which showed a diverticulum through the posterior pharyngeal wall, suggestive of a ZD. Esophagogastroduodenoscopy showed a pouch with erythematous mucosa. Under general anesthesia, diverticulectomy and myotomy were performed. After an uneventful recovery and adequate oral intake, the patient remains free of symptoms at 4 months of follow-up.

Full Text Available Giant sigmoid diverticulum (GSD is a rare complication of diverticulosis. These lesions arise from herniations of the mucosa through the muscle wall which progressively enlarge with colonic gas to become large air-filled cysts evident on plain X-ray and CT scans. We present a rare case of a 72-year-old female presenting with abdominal distention, abdominal tenderness, and fever who developed a type 1 giant sigmoid diverticulum (pseudodiverticulum that subsequently formed an intra-abdominal abscess and an accompanying type 2 diverticulum as well. The patient was treated with surgical resection of the diverticulum with a primary anastomosis and abscess drainage. The patient’s postoperative course was uneventful. This case helps to support the need for the consideration of GSD in patients aged 60 and older with a history of diverticulosis and presenting with abdominal discomfort and distension.

Huge uterine-cervical diverticulum mimicking as a cyst

S Chufal

2012-01-01

Full Text Available Here we report an incidental huge uterine-cervical diverticulum from a total abdominal hysterectomy specimen in a perimenopausal woman who presented with acute abdominal pain. The diverticulum was mimicking with various cysts present in the lateral side of the female genital tract. Histopathological examination confirmed this to be a cervical diverticulum with communication to uterine cavity through two different openings. They can attain huge size if left ignored for long duration and present a diagnostic challenge to clinicians, radiologists, as well as pathologists because of its extreme rarity. Therefore, diverticula should also be included as a differential diagnosis. Its histopathological confirmation also highlights that diverticula can present as an acute abdomen, requiring early diagnosis with appropriate timely intervention. Immunohistochemistry CD 10 has also been used to differentiate it from a mesonephric cyst.

Early identification and quantification of bladder damage in pediatric patients with congenital anomalies of the kidney and urinary tract (CAKUT) is crucial to guiding effective treatment and may affect the eventual clinical outcome, including progression of renal disease. We have developed a novel approach based on the convex hull to calculate bladder wall trabecularity in pediatric patients with CAKUT. The objective of this study was to test whether our approach can accurately predict bladder wall irregularity. Twenty pediatric patients, half with renal compromise and CAKUT and half with normal renal function, were evaluated. We applied the convex hull approach to calculate T, a metric proposed to reflect the degree of trabeculation/bladder wall irregularity, in this set of patients. The average T value was roughly 3 times higher for diseased than healthy patients (0.14 [95% confidence interval, 0.10-0.17] versus 0.05 [95% confidence interval, 0.03-0.07] for normal bladders). This disparity was statistically significant (P hull-based procedure can measure bladder wall irregularity. Because bladder damage is a reversible precursor to irreversible renal parenchymal damage, applying such a measure to at-risk pediatric patients can help guide prompt interventions to avert disease progression. © 2017 by the American Institute of Ultrasound in Medicine.

Giant sigmoid diverticulum with coexisting metastatic rectal carcinoma: a case report

Directory of Open Access Journals (Sweden)

Quinn Aidan

2010-10-01

Full Text Available Abstract Introduction Giant diverticulum of the colon is a rare but clinically significant condition, usually regarded as a complication of an already existing colonic diverticular disease. This is the first report of a giant diverticulum of the colon with a co-existing rectal carcinoma. Case presentation We report a case of a 66-year-old Caucasian woman who presented with lower abdominal pain, chronic constipation and abdominal swelling. Preoperative abdominal computed tomography revealed a giant diverticulum of the colon with a coexisting rectal carcinoma and pulmonary metastasis revealed on a further thoracic computed tomography. An en bloc anterior resection of the rectum along with sigmoid colectomy, partial hysterectomy and right salpingoophorectomy was subsequently performed due to extensive adhesions. Conclusion This report shows that the presence of a co-existing distal colorectal cancer can potentially lead to progressive development of a colonic diverticulum to become a giant diverticulum by increasing colonic intra-luminal pressure and through the ball-valve mechanism. This may be of interest to practising surgeons and surgical trainees.

2015-05-01

Urethral diverticula with calculi have a low incidence as reported in the literature. Diverticulum of female urethra is rare, often discovered due to associated complications. We report a case of diverticulum of the female urethra containing giant calculi in a 62-year-old multiparous woman. She consulted with our office due to dysuria and a hard, painful periurethral mass in the anterior vagina wall. The diverticulum was approached surgically by a vaginal route, and local extraction of the calculi and subsequent diverticulectomy successfully treated the condition.Diagnosis of a complicated diverticulum can be easily achieved if one possesses a high degree of clinical symptoms.

2012-07-01

Full Text Available Periampullary duodenal diverticula are not uncommon and are usually asymptomatic although complications may occasionally occur. Here, we report the case of a 72-year-old woman who presented with painless obstructive jaundice. Laboratory tests showed abnormally elevated serum concentrations of total and direct bilirubin, of alkaline phosphatase, of γ-glutamyl transpeptidase, and of aspartate and alanine aminotransferases. Serum concentrations of the tumor markers carbohydrate antigen 19-9 and carcinoembryonic antigen were normal. Abdominal ultrasonography showed dilatation of the common bile duct (CBD, but no gallstones were found either in the gallbladder or in the CBD. The gallbladder wall was normal. Computed tomography failed to detect the cause of CBD obstruction. Magnetic resonance imaging and magnetic resonance cholangiopancreatography revealed a periampullary diverticulum measuring 2 cm in diameter and compressing the CBD. The pancreatic duct was normal. Hypotonic duodenography demonstrated a periampullary diverticulum with a filling defect corresponding to the papilla. CBD compression by the diverticulum was considered as the cause of jaundice. The patient was successfully treated by surgical excision of the diverticulum. In conclusion, the presence of a periampullary diverticulum should be considered in elderly patients presenting with obstructive jaundice in the absence of CBD gallstones or of a tumor mass. Non-interventional imaging studies should be preferred for diagnosis of this condition, and surgical or endoscopic interventions should be used judiciously for the effective and safe treatment of these patients.

Heterotopic pancreatic tissue of the stomach leading to gastric diverticulum and upper gastro-intestinal bleeding

Directory of Open Access Journals (Sweden)

Silviu Stoian

2016-11-01

Full Text Available Heterotopic pancreatic tissue of the stomach is a rare condition. Gastric diverticulum is also a rare condition, mostly located at the fornix. Therefore, the existence of a pyloric gastric diverticulum containing a submucosal tumor proved to be heterotopic pancreatic tissue of the stomach is an extremely rare condition. The patient was a young thin male with epigastralgia chronically treated for gastritis/ulcer. Following an episode of melena, he underwent gastroscopy that diagnosed antral gastric diverticulum containing a polyp. The lesion was surgically removed. The pathology report stated: heterotopic pancreatic tissue of the stomach with secondary development of a traction diverticulum. Heterotopic pancreas tissue of the stomach is a rare condition but the association with gastric diverticulum is completely unusual. The possibility of the ectopic tissue leading to secondary diverticulum development should be considered.

Full Text Available Urethral stones in adults are rare and usually encountered with urethral stricture or diverticulum. We report a 54 years old gentleman who presented with urinary retention due to a large urethral calculus impacted in bulbar urethra with multiple stones in anterior and posterior urethral diverticulum. On examination a mass of size 5.5cmx4cmx3cm was palpable at anterior perineum with a fistulous tract from which pus was oozing out. On retrograde urethrogram a large urethral calculus with bulbar diverticulum and multiple radio opacity in prostatic area were revealed. Patient was managed by suprapubic cystostomy initially and later on by external urethrotomy, diverticulectomy, urethroscopic removal of multiple stones in prostatic urethral diverticulum and urethroplasty.

Erol, Cengiz; Koplay, Mustafa; Olcay, Ayhan; Kivrak, Ali Sami; Ozbek, Seda; Seker, Mehmet; Paksoy, Yahya

2012-01-01

Objectives: Our aim was to evaluate congenital left ventricular wall abnormalities (clefts, aneurysms and diverticula), describe and illustrate imaging features, discuss terminology problems and determine their prevalence detected by cardiac CT in a single center. Materials and methods: Coronary CT angiography images of 2093 adult patients were evaluated retrospectively in order to determine congenital left ventricular wall abnormalities. Results: The incidence of left ventricular clefts (LVC) was 6.7% (141 patients) and statistically significant difference was not detected between the sexes regarding LVC (P = 0.5). LVCs were single in 65.2% and multiple in 34.8% of patients. They were located at the basal to mid inferoseptal segment of the left ventricle in 55.4%, the basal to mid anteroseptal segment in 24.1%, basal to mid inferior segment in 17% and septal–apical septal segment in 3.5% of cases. The cleft length ranged from 5 to 22 mm (mean 10.5 mm) and they had a narrow connection with the left ventricle (mean 2.5 mm). They were contractile with the left ventricle and obliterated during systole. Congenital left ventricular septal aneurysm that was located just under the aortic valve was detected in two patients (0.1%). No case of congenital left ventricular diverticulum was detected. Conclusion: Cardiac CT allows us to recognize congenital left ventricular wall abnormalities which have been previously overlooked in adults. LVC is a congenital structural variant of the myocardium, is seen more frequently than previously reported and should be differentiated from aneurysm and diverticulum for possible catastrophic complications of the latter two.

Esta es una afección infrecuente, mal interpretada y potencialmente letal. Se ha descrito una amplia variedad de manifestaciones clínicas, y el diagnóstico se basa en el examen físico, los resultados radiográficos y electrocardiográficos. Estos últimos son indispensables, pues con el Doppler en color se puede observar el cortocircuito (shunt desde el ventrículo hasta la cámara diverticular, alternativamente en sístole y diástole. La angiocardiografía, la tomografía axial y sobre todo la resonancia magnética son, sin duda, elementos que contribuyen a corroborar el diagnóstico. Diferentes técnicas quirúrgicas se han empleado con éxito en la reparación de este defecto.Authors describe the case of an African schoolboy aged 7, with a congenital diverticulum of left ventricle successfully treated by surgery. This is a uncommon affection, misinterpreted and potentially lethal. Many clinical manifestations have been described and the diagnosis is based on the physical examination, radiographic and electrocardiographic results. These latter are essential since with the use of color-Doppler it is possible to note the shunt from the ventricle up to the diverticulum camera in systole and in diastole. The angiocardiography, axial tomography (AT and mainly the magnetic resonance (MR are undoubtedly, elements contributing to corroborate the diagnosis. Different surgical techniques have been successfully used in repair of this defect.

Severe congenital penile torsion with anterior urethral diverticulum: A case report

Directory of Open Access Journals (Sweden)

Amilal Bhat

2018-03-01

Full Text Available Introduction: We present a rare case of severe penile torsion of 180° along with giant congenital anterior urethral diverticula. Presentation of these two rare anomalies together is extremely rare and has not been reported yet. The extreme rarity of the case and its management warrants this presentation. Observation: A 5 years old boy presented to us as a case of epispadias with post-void dribbling and wetting of the underwears. On examination, he was found to be a case of severe congenital penile torsion with diversion and rotation of median raphae in a counterclockwise fashion upto the midline dorsally confirming 180° torsion. During voiding, there was appearance of a swelling in distal penile region with passage of urinary drops while compressing it. Micturating cystourethrogram showed diverticula in penile and bulbar urethra. Torsion was completely corrected by penile de-gloving in a plane between two layers of buck fascia and mobilization of the urethra along with spongiosum proximally upto the penoscrotal junction and distally upto the glans. Diverticula was laid open and underwent urethroplasty along with double breasting of thickened diverticular tissue. Torsion was completely corrected after surgery. Post-operative recovery was uneventful. Urine culture was sterile and uroflowmetry showed maximal urinary flow of 12 ml/s at 3 months postoperatively. Conclusions: Penile de-gloving and adequate urethral mobilization corrects the severe penile torsion of 180°. Correction of severe torsion and urethroplasty is feasible in a single stage with good results.

2008-01-01

Full Text Available PURPOSE: To report our initial experiences with laparoscopic partial cystectomy for urachal and bladder malignancy. MATERIALS AND METHODS: Between March 2002 and October 2004, laparoscopic partial cystectomy was performed in 6 cases at 3 institutions; 3 cases were urachal adenocarcinomas and the remaining 3 cases were bladder transitional cell carcinomas. All patients were male, with a median age of 55 years (45-72 years. Gross hematuria was the presenting symptom in all patients, and diagnosis was established with trans-urethral resection bladder tumor in 2 patients and by means of cystoscopic biopsy in the remaining 4 patients. Laparoscopic partial cystectomy was performed using the transperitoneal approach under cystoscopic guidance. In each case, the surgical specimen was removed intact entrapped in an impermeable bag. One patient with para-ureteral diverticulum transitional cell carcinoma required concomitant ureteral reimplantation. RESULTS: All six procedures were completed laparoscopically without open conversion. The median operating time was 110 minutes (90-220 with a median estimated blood loss of 70 mL (50-100. Frozen section evaluations of bladder margins were routinely obtained and were negative for cancer in all cases. The median hospital stay was 2.5 days (2-4 and the duration of catheterization was 7 days. There were no intraoperative or postoperative complications. Final histopathology confirmed urachal adenocarcinoma in 3 cases and bladder transitional cell carcinoma in 3 cases. At a median follow-up of 28.5 months (range: 26 to 44 months, there was no evidence of recurrent disease as evidenced by radiologic or cystoscopic evaluation. CONCLUSIONS: Laparoscopic partial cystectomy in carefully selected patients with urachal and bladder cancer is feasible and safe, offering a promising and minimally invasive alternative for these patients.

Yeon, Kyung Mo; Kook, Shin Ho

1990-01-01

Congenital urethral valve is the common cause of hydronephrosis in newborn infants and the most common cause of bladder outlet obstruction in male children. We reviewed and analysed radiological findings and associated anomalies of 16 cases of congenital urethral valve which were examined during the period from January 1985 to December 1989. The most frequent age was under one year old (56%). The main symptoms were urinary dribbing (37.5%), weak stream (25%) and urinary frequency and incontinence (25%). Anterior urethral valve (AUV) was 5 cases (31%) and posterior urethral valve (PUV) was 11 cases(69%), in which 10 cases were Type I and one case was Type III. Bladder wall thickening was seen in all cases and its severity was partly correlated with the degree of vesicoureteral reflux (VUR). VUR was observed in 12 cases (75%), and relatively severe in older age group. The degree of VUR was milder in AUV than PUV. Hydronephrosis was more severe in PUV than in anterior one, and its degree was correlated with the severity of VUR. Associated anomalies were ectopic urethral opening (2 cases), PDA (1 case), congenital megacolon (1 case) and patent urachus (1 case) in PUV. So early diagnosis and treatment of congenital urethral valve is essential to the prevention of renal damage

Torsion of Atypical Meckel’s Diverticulum Treated by Laparoscopic-Assisted Surgery

2017-01-01

Full Text Available Introduction. Meckel’s diverticulum (MD is the most common congenital anomaly of the intestine, with an incidence of 2~4%. Of those, only 2% of patients with MD are symptomatic. Torsion of MD is extremely rare, and only a dozen cases have been previously reported. Case Report. The patient was a 49-year-old male who presented to our emergency room with a chief complaint of lower abdominal pain. Computed tomography imaging revealed an irregular polycystic mass connected to the small intestine that measured 7.5 cm in a diameter. A laparoscopic-assisted partial resection of the jejunum was performed. The lesion was found to have caused torsion and was located 130 cm from the ileocecal valve. The specimen was polycystic in appearance and showed communicating links with the submucosal layer of jejunum but not with the lumen. The pathological diagnosis was a torsion of an atypical presentation of MD. Conclusion. This case was different from typical cases of MD in that it was located on significantly oral side and had the appearance of polycystic morphology.

Laparoscopic-assisted resection of a giant colonic diverticulum: a case report

Collin Jacqueline E

2009-05-01

Full Text Available Abstract Introduction Diverticular disease of the colon is a common benign condition. The majority of patients with diverticular disease are asymptomatic and are managed non-operatively, however complications such as perforation, bleeding, fistulation and stricture formation can necessitate surgical intervention. A giant colonic diverticulum is defined as a diverticulum larger than 4 cm in diameter. Despite the increasing incidence of colonic diverticular disease, giant colonic diverticula remain a rare clinical entity. Case presentation This is the first reported case of laparoscopic-assisted resection of a giant colonic diverticulum. We discuss the symptoms and signs of this rare complication of diverticular disease and suggest investigations and management. Reflecting on this case and those reported in the literature to date, we highlight potential diagnostic difficulties and consider the differential diagnosis of intra-abdominal gas-filled cysts. Conclusion The presence of a giant colonic diverticulum carries substantial risk of complications. Diagnosis is based on history and examination supported by abdominal X-ray and computed tomography findings. In view of the chronic course of symptoms and potential for complications, elective surgical removal is recommended. Colonic resection is the treatment of choice for this condition and, where possible, should be performed laparoscopically.

Gastric diverticulum causing gastric outlet obstruction in the setting of duodenal atresia

Directory of Open Access Journals (Sweden)

Devashis Mukherjee

2018-04-01

Full Text Available Duodenal obstruction due to duodenal atresia occurs in 1 in 10,000 live births and is the most common type of intestinal obstruction in neonates [1–3]. Gastric outlet obstruction in the newborn period from causes other than hypertrophic pyloric stenosis is very uncommon [3]. Potential etiologies include gastric volvulus, antral web, and duplication cysts. Gastric diverticula in the infant is even more rare, with only a few case reports published, and only one describes a gastric diverticulum in the presence of a duodenal atresia [4–8]. In this report, we describe the first case of a gastric outlet obstruction due to a gastric diverticulum in the presence of duodenal atresia.

Meckel's diverticulum (MD) is the most prevalent congenital anomaly of the gastrointestinal tract and often presents a diagnostic challenge. Patients with trisomy 18 frequently have MD, but the poor prognosis and lack of consensus regarding management for neonates has meant that precise information on the clinical manifestations in infants and children with MD is lacking. We describe the cases of three children with trisomy 18 who developed symptomatic MD. Intussusception was diagnosed in Patient 1, intestinal volvulus in Patient 2, and gastrointestinal bleeding in Patient 3. All three patients underwent surgical treatment and only the Patient 1 died due to pulmonary hypertensive crisis. The other two patients experienced no further episodes of abdominal symptoms. In patients with trisomy 18, although consideration of postoperative complications and prognosis after surgical treatment is necessary, symptomatic MD should carry a high index of suspicion in patients presenting with acute abdomen. © 2015 Wiley Periodicals, Inc.

Posterior urethral diverticulum (PUD) is one of the most common postoperative complications associated with anorectal malformation (ARM) correction. To describe our MRI protocol for evaluating acquired PUD following ARM surgery, and associated imaging findings. Two radiologists retrospectively reviewed 61 pelvic MRI examinations performed for postoperative ARM for PUD identification and characteristics. Associated clinical, operative and cystoscopy reports were also reviewed and compared to MRI. An abnormal retrourethral focus suspicious for PUD was identified at MRI in 13 patients. Ten of these patients underwent subsequent surgery or cystoscopy, and PUD was confirmed in five. All of the confirmed PUD cases appeared as cystic lesions that were at least 1 cm in diameter in two imaging planes. Four of the false-positive cases were punctate retrourethral foci that were visible only on a single MRI plane. One patient had a seminal vesical cyst mimicking a PUD. Pelvic MRI can be a useful tool in the postoperative assessment of suspected PUD associated with ARM. Radiologists should have a high clinical suspicion for a postoperative PUD when a cystic lesion posterior to the bladder/posterior urethra is encountered on two imaging planes in these patients.

We report a case of perforated colonic diverticulum in Cushing's disease. Although perforated diverticuli have been described in patients with Cushing's syndrome secondary to exogenous glucocorticoids, this complication has not been described in patients with Cushing's disease. Patients with hypercortisolism, from either exogenous or endogenous sources, should be monitored for diverticular perforation.

The aim of this study was to evaluate the clinical relevance and prognostic value of preoperative and postoperative oesophagography in patients with Zenker's diverticulum. The medical records of 155 patients who underwent surgical treatment (with an endoscopic or transcervical approach) for Zenker's diverticulum between 1992 and 2010 in a tertiary referral centre were retrospectively evaluated. The size of the diverticula on oesophagography, recognizable muscular septum, and protection of the diverticulum were assessed relative to the surgical procedures performed. The incidence of diverticular remnants on postoperative oesophagography was also assessed relative to the surgical procedure. It was investigated whether the detection of a residual pharyngeal pouch and filling of it with contrast medium were related to the patients' immediate postoperative symptoms and the development of symptomatic recurrence. Larger diverticula (Brombart III-IV) were manageable significantly more often with endoscopic procedures (P = 0.007). Residual diverticulum and filling with contrast medium were strongly associated with prolonged dysphagia immediately postoperatively (P = 0.005 and P = 0.009, respectively). However, these parameters failed to correlate significantly with a symptomatic recurrence. Preoperative oesophagography proved to be extremely important for surgical planning, with the surgeon's personal preference seeming to be the driving indicator in many cases. Postoperative oesophagography is only useful for excluding postoperative complications in the immediate postoperative phase and did not have a prognostic value as to a recurrence of the disease.

We present a rare case of midgut volvulus that was associated with a large, small-bowel diverticulum in a 77-year-old woman presenting with chronic recurrent abdominal pain. The CT showed the characteristic whirl sign of twisted mesentery, the small bowel loops along the superior mesenteric artery and a large sac-like small-bowel diverticulum. A small bowel series also demonstrated a corkscrew appearance of proximal jejunum, a finding suggestive of midgut volvulus, and a large jejunal diverticulum. During the laparotomy, the small bowel was seen twisted counterclockwise 270 .deg.. The mesenteric root was very shortened. A 4 cm sized diverticulum was seen on the mesenteric border of jejunum, on the portion about 40 cm distal from the Treitz ligament.

A 42-year-old man with a history of recurrent urethral stenosis, recurrent urinary tract infection and macroscopic hematuria has referred to our clinic. He underwent several internal urethrotomies and currently using clean intermittent self-catheterization. During the internal urethrotomy, we noted a large posterior urethral diverticulum (UD) between verumontanum and bladder neck. His obstructive symptoms were resolved after the catheter removal. But perineal discomfort, urgency and dysuria were prolonged about 3-4 weeks. Urinalysis and urine culture confirmed recurrent urinary tract infections. Due to this conditions and symptoms, we planned a surgical approach which was planned as transperitoneal robotic-assisted laparoscopic approach. This technique is still applied for the diverticulectomy of the bladder. In addition to this we utilized the cystoscopy equipments for assistance. During this process, cystoscope was placed in the UD to help the identification of UD from adjacent tissues like seminal vesicles by its movement and translumination. Operating time was 185 min. On the post-operative third day he was discharged. Foley catheter was removed after 2 weeks. Urination was quite satisfactory. His perineal discomfort was resolved. The pathology report confirmed epidermoid (tailgut) cyst of the prostate. Urethrogram showed no radiologic signs of UD after 4 weeks. Irritative and obstructive symptoms were completely resolved after 3 months. No urinary incontinence, erectile dysfunction or retrograde ejaculation was noted. While posterior UD is an extremely rare situation, surgical treatment of posterior UD remains uncertain. To our knowledge, no above-mentioned cystoscopy assisted robotic technique for the treatment was described in the literature.

Full Text Available Midgut volvulus in adults is a rare entity that may present with intermittent colicky abdominal pain mixed with completely asymptomatic episodes. This small bowel twist may result in complications of obstruction, ischemia, hemorrhage, or perforation. With a midgut volvulus, complications may be life-threatening, and emergent surgical intervention is the mainstay of treatment. This current case involves an 80-year-old woman with intermittent abdominal pain with increasing severity and decreasing interval of time to presentation. A CAT scan revealed mesenteric swirling with possible internal hernia. A diagnostic laparoscopy followed by laparotomy revealed a midgut volvulus, extensive adhesions involving the root of the mesentery, and a large jejunal diverticulum. The adhesions were lysed enabling untwisting of the bowel, allowing placement of the small bowel in the correct anatomic position and resection of the jejunal diverticulum. This is a rare case of midgut volvulus with intermittent abdominal pain, associated with jejunal diverticulum managed successfully. A midgut volvulus should be considered in the differential diagnosis of a patient who present with a small bowel obstruction secondary to an internal hernia, especially when a swirl sign is present on the CAT scan.

Cancer Committee of the French Association of Urology (CCAFU) conducted a review of the epidemiology, diagnosis and treatment of intradiverticular bladder tumours (TVID) and proposed therapeutic management. A bibliographic research in French and English using Medline(®) with the keywords "tumor", "bladder" and "diverticulum" was performed. TVID are more frequently of stage T ≥ 3a and with non urothelial histology than classical bladder tumors. At diagnosis, the risk of underestimation of the extent and multifocality of the tumor was described. Their prognosis, that was more pejorative than conventional tumors, should impelled to limit the indications of conservative treatment. The evidence levels of analyzed publications were low, with C level according to Sackett score. the specificities of the TVID have lead the CCAFU to propose specific therapeutic guidelines, based on poor evidence level. Ta-T1 low grade TVID can be treated by transurethral resection alone or followed by BCG therapy in cases of associated carcinoma in situ. High-grade TVID, unifocal and without associated carcinoma in situ, can be treated by diverticulectomy associated with pelvic lymphadenectomy. High grade TVID, multiple or associated with carcinoma in situ, warranted total cystectomy. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Zenker’s diverticulum and squamous esophageal cancer: a case report

Ion Dina

2017-10-01

Full Text Available Zenker’s diverticulum represents a rare esophageal lesion developed especially in the elderly population due to herniation of esophageal mucosa above the cricopharyngeus muscle. The condition leads to food retention, regurgitation, aspiration, and dysphagia in affected patients. Progressive dysphagia also characterizes malignant diseases of the esophagus like squamous esophageal carcinoma that typically appears in male patients in the seventh decade of life, with a history of cigarette smoking and alcohol abuse. We report a case of a male patient who presented with dysphagia for both solids and liquids along with significant weight loss, and who was diagnosed with medium esophageal cancer associated with Zenker’s diverticulum.

A Meckel diverticulum is an embryonic remnant of the omphalomesenteric duct that occurs in approximately 2% of the population. Most are asymptomatic; however, they are vulnerable to inflammation with subsequent consequences including diverticulitis and perforation. We report an 11-year-old boy who underwent laparoscopic appendectomy for perforated appendicitis at an outside institution. During his convalescence he underwent percutaneous drainage of a presumed postoperative abscess. A follow-up drain study demonstrated an enteric fistula. The drain was slowly removed from the abdomen over a period of 1 week. Three weeks following drain removal the patient reported recurrent nausea and abdominal pain. A CT scan demonstrated a 3.7-cm rim-enhancing air-fluid level with dependent contrast consistent with persistent enteric fistula and abscess. Exploratory laparoscopy was performed, at which time a Meckel diverticulum was identified and resected. This case highlights the diagnostic challenge and limitations of conventional radiology in complicated Meckel diverticulum. (orig.)

Zenker's diverticulum (ZD) is a rare pathology, with a prevalence of between 0.01% and 0.11%. Definitive diagnosis of ZD can be accomplished by contrast radiographic examination (barium oesophagogram, BE); oesophageal manometry (ME) is recommended mainly for those patients suffering from dysphagia and/or gastro-oesophageal reflux. The aims of the present study were to assess whether oropharyngo-oesophageal scintigraphy (OPES) is able (a) to visualise ZD and (2) to demonstrate the corresponding alteration in the swallowing phases. We studied 16 patients (nine male, seven female, mean age 67.4 years), and 17 healthy volunteers (ten male, seven female, mean age 53 years) as a control group. All the patients underwent ME, BE and OPES. Nine patients underwent surgery and six of them were re-evaluated after 6 months. We administered 10 ml of water with 37 MBq of technetium-99m colloid through a straw, acquiring 480 sequential images (0.125 s/frame for a total of 60 s) with the patient standing in front of the gamma camera in the 80 right anterior oblique position. Two static images were performed at the end of the dynamic phase, before and after ingestion of 100 ml of unlabelled water to evaluate the presence of inflammation (persistence of radioactivity in the diverticulum or oesophagus). Study of the sequential scintigraphic images and time-activity curves permitted both qualitative (diverticulum visualisation, multiple deglutitions, reflux, presence of inflammation) and quantitative analyses [oral, pharyngeal and oesophageal transit times and retention indexes, tracheal aspiration percentage] of swallowing disorders. OPES showed a good correlation with the results of other diagnostic techniques usually performed in patients with this pathology, and especially with ME in the evaluation of oropharyngeal phase disorders. Furthermore, OPES is a sensitive and simple technique that is well tolerated and entails a low irradiation dose for patients. (orig.)

Abstract Urethral triplication is a rare congenital anomaly of the lower urinary system, with urethra ending in glans. At the beginning of toilet training, urine output was observed along the rectum. Rigid cystoscopy shows a perineal urethra starting in the posterior urethra. Subsequently, flexible cystoscopy showed entry of epispadic urethra in the bladder immediately superior to the bladder neck. It was running parallel to primary urethra. Then, we observed two most frequent types of urethral duplication in the sagittal plane in a single patient. PMID:29675475

Intussusception is commonly seen in infants. It is occasionally found in adults usually due to carcinomas, colonic diverticuli, polyps and rarely Meckel's diverticulum. An adult male presented with upper abdominal pain, nausea, anorexia and loose stools. The initial investigative workup was unremarkable and patient responded to treatment given for acute gastroenteritis. After 3 days, the pain recurred in right iliac fossa with rebound tenderness and leukocytosis. Surgery was performed with provisional diagnoses of acute appendicitis and/or acute Meckel's diverticulitis. Per-operative findings revealed invaginated Meckel's diverticulum causing non-obstructing intussusception. (author)

Meckel diverticulum is the most common abnormality of the gastrointestinal tract arising from an incomplete obliteration of the vitelline duct during the intrauterine life. Although tumor development in Meckel diverticulum is not a common situation, it can occur due to the persistence of cellular islets with gastric, pancreatic or intestinal origin. The presence of a neuroendocrine tumor arising from Meckel diverticulum is even scarcer. We present the case of a 59-year-old patient in whom a Meckel diverticulum was found during surgery for inguinal hernia; the histopathological and immunohistochemical studies revealed the presence of a well-differentiated neuroendocrine tumor with low mitotic index.

Congenital anterior urethral valves and diverticula: Diagnosis and management in six cases

Directory of Open Access Journals (Sweden)

Rawat Jiledar

2009-01-01

Full Text Available Background: Anterior urethral valves (AUVs are rare congenital anomalies causing lower urinary tract obstruction in children. Although they are referred to as valves, these obstructive structures often occur in the form of a diverticulum. The urethra in these cases shows saccular or bulbar dilatation known as anterior urethral diverticulum (AUD. They typically occur where there is a defect in the corpus spongiosum, leaving a thin-walled urethra. This segment of the urethra balloons out during voiding, simulating a mass that is sometimes visible along the ventral wall of the penis. The swelling is fluctuant and urine dribbles from the meatus on compression. The present study highlights the clinical approach in identifying the condition and its treatment options, especially for those, presenting with urethral diverticula. Materials and Methods: We have studied children with congenital anterior urethral valves and diverticula. Six patients of AUVs with diverticula were admitted during the period of 2000-2007 and were prospectively evaluated. The mean age of presentation was 16 months (15 days to 4 years. Straining at micturition and a palpable penile swelling were the most common presenting features. The diagnosis was established by voiding cystourethrogram (VCUG and supported by ultrasonography (USG. All patients were treated with single-stage open surgical excision except one who died preoperatively due to urosepsis. Initial lay opening of the penoscrotal urethra and delayed repair were done in one patient. Results: The surgical outcome was successful in all but one patient, who died of delayed presentation with severe back pressure changes, urinary ascitis and urosepsis. On long-term follow-up, all patients demonstrated good stream of urine. The renal functions were normal and the patients had no evidence of urinary infections. Conclusion: We propose that, the patients of AUVs, if not excessively delayed for treatment are otherwise well in terms

Evolution of ventricular outpouching through the fetal and postnatal periods: Unabating dilemma of serial observation or surgical correction

Directory of Open Access Journals (Sweden)

2017-07-01

Full Text Available Ventricular outpouching is a rare finding in prenatal sonography and the main differential diagnoses are diverticulum, aneurysm, and pseudoaneurysm in addition to congenital cysts and clefts. The various modes of fetal presentation of congenital ventricular outpouching include an abnormal four-chamber view on fetal two-dimensional echocardiogram, fetal arrhythmia, fetal hydrops, and pericardial effusion. Left ventricular aneurysm (LVA/nonapical diverticula are usually isolated defects. Apical diverticula are always associated with midline thoracoabdominal defects (epigastric pulsating diverticulum or large omphalocele and other structural malformations of the heart. Most patients with LVA/congenital ventricular diverticulum remain clinically asymptomatic but they can potentially give rise to complications such as ventricular tachyarrhythmias, systemic embolism, sudden death, spontaneous rupture, and severe valvular regurgitation. The treatment of asymptomatic LVA and isolated congenital ventricular diverticulum is still undefined. In this review, our aim is to outline a systematic approach to a fetus detected with ventricular outpouching. Starting with prevalence and its types, issues in fetal management, natural course and evolution postbirth, and finally the perpetual dilemma of serial observation or surgical correction is discussed.

Full Text Available No abstract available. Article truncated after 150 words. An 89 year old female nursing home resident with a past medical history of hypertension and coronary artery disease was admitted with generalized weakness and vomiting for two days. Chest x-ray revealed consolidation in the left lung suggestive of pneumonia and she was started on broad spectrum antibiotics. Due to worsening consolidation in both lung fields (Figure 1 a video swallow was done for possible aspiration, which revealed contrast retained within the proximal esophagus within a diverticula in the anterior aspect (Figure 2.

Full Text Available Rectal diverticulum is a rare condition in dogs characterized by formation of a pouch orsac due to hernial protrusion of the mucous membranes through a defect in the muscularcoat of the rectum. A 12-year-old male terrier dog was admitted with a history of a leftperineal swelling, dyschezia and tenesmus during the last five months. Digital rectalexamination identified a weakness in the left pelvic diaphragm and feces-filled sac withinthe lateral wall of the rectum. Positive contrast radiography showed a marked solitarydiverticulum (3.5×4×4.5 cm with wide-orifice neck arising from the left rectal wall.Using a lateral approach, a large rectal diverticulum was found and diverticulectomyfollowing standard herniorrhaphy was performed. The dog recovered uneventfully with nosigns of dyschezia during the next three years. Diverticulectomy by lateral approach andperineal herniorrhaphy produced excellent results.

A 64 year-old woman presented with advanced, transverse colon cancer arising in the diverticulum. Tumor invasion extended beyond the serosa to the anal side of the colon. Anemia and fatigue progressed after 6 months of iron administration. The hemoglobin value was 5.3 g/dL and carcinoembryonic antigen (CEA) level was elevated to 44.2 ng/mL. A palpable and tender fist-sized mass was found in the right upper abdomen. Computed tomography (CT) revealed a low-density mass in the transverse colon invading beyond the serosa to the anal side of the colon. Right hemi-colectomy with lymph node dissection was performed. The resected specimen contained multiple diverticula including the one from which the tumor arose. Histological examination revealed a well-differentiated, tubular adenocarcinoma (UICC TNM T4bN0M0) arising in a transverse colon diverticulum. There has been no recurrence for 2 years. Colon cancer arising in a diverticulum may expand to the extra-serosa and easily invade to the adjacent organ. In such cases, malignancy should be considered.

2014-01-01

Full Text Available A 43-year-old woman presented with 20-year history of leakage of urine per vaginam. She had one failed repair attempt. Pelvic examination with dye test showed leakage of clear urine suggestive of ureterovaginal fistula. The preoperative intravenous urogram revealed duplex ureter and cystoscopy showed normally cited ureteric orifices with two other ectopic ureteric openings and bladder diverticula. The definitive surgery performed was ureteric reimplantation (ureteroneocystostomy of the two distal ureteric to 2 cm superiolateral to the two normal orifices and diverticuloplasty. There was resolution of urinary incontinence after surgery. Three months after surgery, she had urodynamic testing done (cystometry, which showed 220 mLs with no signs of instability or leakage during filling phase but leaked on coughing at maximal bladder capacity. This is to showcase some diagnostic dilemma that could arise with obstetric fistula, which is generally diagnosed by clinical assessment.

Small bowel volvulus with jejunal diverticulum: Primary or secondary?

Shen, Xiao-Fei; Guan, Wen-Xian; Cao, Ke; Wang, Hao; Du, Jun-Feng

2015-09-28

Small bowel volvulus, which is torsion of the small bowel and its mesentery, is a medical emergency, and is categorized as primary or secondary type. Primary type often occurs without any apparent intrinsic anatomical anomalies, while the secondary type is common clinically and could be caused by numerous factors including postoperative adhesions, intestinal diverticulum, and/or tumors. Here, we report a rare case of a 60-year-old man diagnosed with small bowel volvulus using multidetector computed tomography (MDCT) angiography. Further discovery by laparotomy showed one jejunal diverticulum, longer corresponding mesentery with a narrower insertion, and a lack of mesenteric fat. This case report includes several etiological factors of small bowel volvulus, and we discuss the possible cause of small bowel volvulus in this patient. We also highlight the importance of MDCT angiography in the diagnosis of volvulus and share our experience in treating this disease.

2016-01-01

Full Text Available Introduction. The aim of the study was to evaluate our children who are operated on for anomalous congenital band while increasing the awareness of this rare reason of intestinal obstruction in children which causes a diagnostic challenge. Patients and Methods. We retrospectively reviewed the records of fourteen children treated surgically for intestinal obstructions caused by anomalous congenital bands. Results. The bands were located between the following regions: the ascending colon and the mesentery of the terminal ileum in 4 patients, the jejunum and mesentery of the terminal ileum in 3 patients, the ileum and mesentery of the terminal ileum in 2 patients, the ligament of Treitz and mesentery of the jejunum in one patient, the ligament of Treitz and mesentery of the terminal ileum in one patient, duodenum and duodenum in one patient, the ileum and mesentery of the ileum in one patient, the jejunum and mesentery of the jejunum in one patient, and Meckel’s diverticulum and its ileal mesentery in one patient. Band excision was adequate in all of the patients except the two who received resection anastomosis for intestinal necrosis. Conclusion. Although congenital anomalous bands are rare, they should be considered in the differential diagnosis of patients with an intestinal obstruction.

Meckel’s diverticulum (MD) is estimated to affect 1%-2% of the general population, and it represents a clinically silent finding of a congenital anomaly in up to 85% of the cases. In adults, MD may cause symptoms, such as overt occult lower gastrointestinal bleeding. The diagnostic imaging workup includes computed tomography scan, magnetic resonance imaging enterography, technetium 99m scintigraphy (99mTc) using either labeled red blood cells or pertechnetate (known as the Meckel’s scan) and angiography. The preoperative detection rate of MD in adults is low, and many patients ultimately undergo exploratory laparoscopy. More recently, however, endoscopic identification of MD has been possible with the use of balloon-assisted enteroscopy via direct luminal access, which also provides visualization of the diverticular ostium. The aim of this study was to review the diagnosis by double-balloon enteroscopy of 4 adults with symptomatic MD but who had negative diagnostic imaging workups. These cases indicate that balloon-assisted enteroscopy is a valuable diagnostic method and should be considered in adult patients who have suspected MD and indefinite findings on diagnostic imaging workup, including negative Meckel’s scan.

2017-09-01

Full Text Available Aim: To identify and to assess imaging and clinical features of Posterior urethral diverticula (PUD in a single-centre series and include a brief review of literature. Materials and method: Post operative MRI of 140 children from north India were retrospectively reviewed who underwent surgical repair for anorectal malformation (ARM along with the Hospital records. Results: Ten cases had MRI features of posterior urethral diverticulum. All of these patients had undergone primary abdominoperineal pull through (APPT procedure. The lesions ranged between 6 mm and 38 mm in size. Two of these lesions were missed in the post operative MRI report. Only one of these patients was symptomatic and presented with dribbling of urine and gross bilateral vesicoureteric reflux in which the diverticulum was excised surgically. Conclusion: PUD is an under-recognised entity and can be identified in preclinical stage on MRI. Careful assessment of urethra and periurethral structures should be a mandatory step in MRI evaluation of post repair ARM cases. An observational conservative approach in selected asymptomatic patients can be an effective management strategy. Keywords: Posterior urethral diverticulum, MRI, Anorectal malformation

2017-09-01

Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group. CT vascular studies of patients with idiopathic intracranial hypertension with pulsatile tinnitus ( n = 42), without pulsatile tinnitus ( n = 37), and controls ( n = 75) were independently reviewed for the presence of severe transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence according to published criteria. The prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence in patients with idiopathic intracranial hypertension with pulsatile tinnitus was compared with that in the nonpulsatile tinnitus idiopathic intracranial hypertension group and the control group. Further comparisons included differing degrees of transverse sinus stenosis (50% and 75%), laterality of transverse sinus stenosis/sigmoid sinus diverticulum/dehiscence, and ipsilateral transverse sinus stenosis combined with sigmoid sinus diverticulum/dehiscence. Severe bilateral transverse sinus stenoses were more frequent in patients with idiopathic intracranial hypertension than in controls ( P tinnitus within the idiopathic intracranial hypertension group. Sigmoid sinus dehiscence (right- or left-sided) was also more common in patients with idiopathic intracranial hypertension compared with controls ( P = .01), but there was no significant association with pulsatile tinnitus within the idiopathic intracranial hypertension group. While our data corroborate previous studies demonstrating increased prevalence of sigmoid sinus diverticulum

Full Text Available Objective: To report the management of urinary tract obstruction and infection in a pregnant woman with unrepaired bladder exstrophy. Case Report: A 27-year-old pregnant woman with unrepaired bladder exstrophy was referred to our hospital with a complaint of bilateral flank pain in the second trimester. After two-dimensional abdominal ultrasound, magnetic resonance imaging and a urine analysis, she was diagnosed with an upper urinary tract infection due to ureteral obstruction secondary to unrepaired congenital bladder exstrophy and an intrauterine pregnancy. J-tube insertion was performed after locating the ureteral orifices and antibiotics were administered. Symptoms rapidly resolved. She delivered a normal male infant by caesarean section at 34 weeks of gestation. Conclusion: Standard urological management of the ureteral obstruction in pregnancy was successful in this extreme case of unrepaired bladder exstrophy associated with an intrauterine pregnancy. The perinatal outcome was good. Keywords: Bladder exstrophy, Infection, Pregnancy, Urinary tract

Our case is a 62-year-old diabetic man with a long-standing history of regurgitation, halitosis, recurrent chest infection, and most recently upper gastro-intestinal bleeding. He was diagnosed 10 years earlier with an epiphrenic esophageal diverticulum, and also has a family history of this condition. Barium study revealed a 10x10 cm epiphrenic diverticula with a 4 cm neck, the lower margin of the opening lying 6 cm from the gastro-esophageal junction. Endoscopy confirmed the x-ray findings, and motility studies were within normal limits. The patient underwent laparoscopic excision of the diverticulum via the trans-abdominal approach. Histopathological examination revealed this diverticulum to be of the true type. (author)

Background: Although the imaging features of sigmoid sinus diverticulum induced pulsatile tinnitus (PT) have been presented in some extent, detailed imaging findings still have not been systematically evaluated and precise diagnostic radiographic criteria has not been established. Purpose: To examine the computed tomography (CT) characteristics of sigmoid sinus diverticulum accompanied with PT. Material and Methods: Fifteen PT patients with sigmoid sinus diverticula proven by surgery were recruited after consenting. CT images of 15 patients were obtained and analyzed, including features of diverticula, brain venous systems, integrity of the sigmoid plate, and the degree of temporal bone pneumatization. Results: Sigmoid sinus diverticulum was located on the same side of PT in 15 patients. Diverticula originated at the superior curve of the sigmoid sinus in 11 patients and the descending segment of the sigmoid sinus in four patients. Sigmoid sinus diverticula focally eroded into the adjacent mastoid air cells in 12 patients and mastoid cortex in three patients. Among eight patients with unilateral dominant brain venous systems, the diverticula were seen on the dominant side in seven patients and non-dominant side in one patient. In contrast, the other seven patients showed co-dominant brain venous systems, with three presenting diverticula on the right side and four on the left. More notably, dehiscent sigmoid plate on the PT side was demonstrated in all patients. In addition, temporal bone hyper-pneumatization was found in nine patients, good and moderate pneumatization in three patients, respectively. Conclusion: Dehiscent sigmoid plate and extensive temporal bone pneumatization are two important imaging characteristics of the PT induced by sigmoid sinus diverticulum

Full Text Available Uterovaginal malformations, occur in 0.16% of women and contribute to the problems of infertility, recurrent pregnancy loss, dysmenorrhea, dyspareunia, amenorrhea and a poor outcome in pregnancy. True diverticulum is an exceedingly rare anomaly and is like a tubular formation connected to uterine cavity that ends in a cul-de sac and It is not classified as any of mullerian duct anomalies. In this article a case of uterine diverticulum rupture due to pregnancy in a 19 years old woman with nausea, vomiting and abdominal pain is reported. Although rare, in complicated pregnancy we should think to genital tract anomalies.

Full Text Available Background. Diverticulum, one of the long-term sequelae of cesarean section, can cause abnormal uterine bleeding and increase the risk of uterine scar rupture. In this study, we aimed to evaluate the efficacy of combined laparoscopic and hysteroscopic repair, a newly occurring method, treating post-cesarean section uterine scar diverticulum. Methods. Data relating to 40 patients with post-cesarean section uterine diverticulum who underwent combined laparoscopic and hysteroscopic repair were retrospectively analyzed. Preoperative clinical manifestations, size of uterine defects, thickness of the lower uterine segment (LUS, and duration of menstruation were compared with follow-up findings at 1, 3, and 6 months after surgery. Results. The average preoperative length and width of uterine diverticula and thickness of the lower uterine segment were recorded and analyzed. The average durations of menstruations at 1, 3, and 6 months after surgery were significantly shorter than the preoperative one (p<0.05, respectively. At 6 months after surgery, the overall success improvement rate of surgery was 90% (36/40. Three patients (3/40 = 7.5% developed partial improvement, and 1/40 (2.5% was lost to follow-up. Conclusions. Our findings showed that combined treatment with laparoscopy and hysteroscopy was an effective method for the repair of post-cesarean section uterine diverticulum.

2012-12-01

Esophageal diverticula are uncommon lesions that are usually classified according to their location (cervical, thoracic, or epiphrenic), or underlying pathogenesis (pulsion or traction), and their morphology (true or false).The majority of esophageal diverticula are acquired lesions that occur predominantly in elderly adults. Pulsion, or false, diverticula are the most commonly encountered type of esophageal diverticula noticed at the level of cricopharyngeus muscle, occur as a localized outpouchings that lacks a muscular coat, and as such their wall is formed entirely by mucosa and submucosa. True, or traction, esophageal diverticulum (TED) is seen in the middle one third of the thoracic esophagus in a peribronchial location, occurs secondary to mediastinal inflammatory lesions such as tuberculosis or histoplasmosis. The resultant desmoplastic reaction in the paraesophageal tissue causes full thickness pinching on the esophageal wall, producing a conical, broad-mouthed true diverticulum. They often project to the right side because subcarinal lymph nodes in this area are closely associated with the right anterior wall of the esophagus. TED usually presents with symptoms such as dysphagia, postural regurgitation, belching, retrosternal pain, heartburn, and epigastric pain. As in patients with pharyngoesophageal (Zenker's) diverticula, pulmonary symptoms are often present but underestimated in TED patients. These symptoms range from mild nocturnal cough to life-threatening massive aspiration. In this particular report we describe a rare case of TED presenting as a symptomatic upper gastrointestinal bleeding. Diagnostic evaluation of TED includes chest X-ray, barium esophagogram and manometry. A significant proportion of lower esophageal diverticula are associated with motility disorders. Management of TED include treating the underlying cause sometimes a surgical resection of diverticulum along with esophageal myotomy is necessitated in symptomatic patients.

Full Text Available Background: Meckel's diverticulum (MD is the one of the most common congenital malformation of gastrointestinal tract and has varied clinical presentations. We are presenting here our 12-year experiences with MD in children at tertiary care hospital in North India. It highlights the fact that isolated gangrene of MD can occur, and it is associated with increased morbidity. Materials and Methods: This retrospective study is conducted by analysing the medical records of the patients who were operated for MD in the last 12 years in paediatric surgery department at our hospital. Results: Sixty-five patients were operated for MD in study period; in this 52 were males and 13 were females with mean age of presentation 3.2 years. The most common presentation was intestinal obstruction seen in 86.1% (56 cases. Intestinal haemorrhage was seen in 4.6% (3 cases and diverticulitis in 3% (2 cases. Perforation of the gut with peritonitis was present in 6.1% (four cases. Cause of obstruction was intussusception in 21.4% (12 cases, fibrous band connected to umbilicus in 17.8% (10 cases, volvulus in 17.8% (10 cases, kinking in 16.0% (9 cases, knotting in 14.2% (8 cases and herniation of gut below in 12.5% (7 cases. Isolated gangrene of MD was present in ten cases with intestinal obstruction. The ectopic gastric mucosa was seen in three and pancreatic mucosa in two cases. Mortality and morbidity during the study were one and three cases, respectively. Conclusion: MD may remain clinically silent for lifetime, or it may have life-threatening complications. In our series, intestinal obstruction and not the haemorrhage was the most common presentation. Isolated gangrene of MD with obstruction was present in significant numbers, which we failed to find in literature.

Full Text Available Congenital anomalies of the urinary system are relatively common anomalies. In Bosnia and Herzegovina there is no existent unique evidence of congenital anomalies and registries. The aim of this study was to obtain the frequency of different urinary tract anomalies types and their sex distribution among cases hospitalized in the Department of Pediatric Surgery of the University of Sarajevo Clinics Centre, Bosnia and Herzegovina, during the period from January 2002 to December 2006. Retrospective study was carried out on the basis of clinical records. Standard methods of descriptive statistics were performed for the data analysis. Among 289 patients that were surgically treated 62,37% of the patients were male patients, while 37,63% were female patients. Twenty nine different urinary system anomalies types were found in this study. These were: vesicoureteral reflux (99 cases or 30,75%, hypospadias (62 cases or 19,26%, pelviureteric junction obstruction (42 cases or 13,04%, megaureter (35 cases or 10,87%, duplex pelvis and ureter (16 cases or 4,97%, bladder diverticulum (8 cases or 2,48%, ureterocoele (7 cases or 2,17%, stenosis of the external urethral opening (6 cases or 1,86%, ectopic kidney, duplex kidney and pelvis (each 5 cases or 1,55%, polycystic kidneys and urethral stricture (each 4 cases or 1,24%, multicystic kidney (3 cases or 0,93%, kidney agenesis, ureter agenesis, urethral diverticulum, ectopic ureter, horseshoe kidney and fetal kidney (each 2 cases or 0,62%, renal aplasia, urethral atresia, renal cyst, urachal cyst, epispadias, bladder exstrophy, renal hypoplasia, renal malrotation and Prune-Belly syndrome (each 1 case or 0,31%. According to this study, urinary tract anomalies were more common in male than in female patients (62,37%, Generally, the most frequent anomaly type was vesicoureteral reflux in total number of 99 cases, and in females (66 cases, but hypospadias was the most common anomaly in males (62 cases.

Urinary bladder malformations associated with bladder outlet obstruction are a frequent cause of progressive renal failure in children. We here describe a muscarinic acetylcholine receptor M3 (CHRM3) (1q41-q44) homozygous frameshift mutation in familial congenital bladder malformation associated with a prune-belly-like syndrome, defining an isolated gene defect underlying this sometimes devastating disease. CHRM3 encodes the M3 muscarinic acetylcholine receptor, which we show is present in developing renal epithelia and bladder muscle. These observations may imply that M3 has a role beyond its known contribution to detrusor contractions. This Mendelian disease caused by a muscarinic acetylcholine receptor mutation strikingly phenocopies Chrm3 null mutant mice. Copyright © 2011 The American Society of Human Genetics.

Endoscopic ultrasound with double-balloon endoscopy for the diagnosis of inverted Meckel’s diverticulum: a case report

Directory of Open Access Journals (Sweden)

Araki Akihiro

2012-09-01

Full Text Available Abstract Introduction Inverted Meckel’s diverticulum has usually been misdiagnosed in the cases based on computed tomography images presented in the literature. The final diagnosis was made intra-operatively or by pathology reports after surgery. Despite this, preoperative diagnosis could be made successfully by using endoscopic ultrasound with double-balloon endoscopy prior to surgery. Case presentation A 60-year-old Japanese woman with severe anemia complained of several episodes of black stool over the preceding 2 years. Abdominal computed tomography showed a 3.0-cm low-density tumor in the ileum, suggesting a diagnosis of intestinal lipoma. Examination of the tumor by endoscopic ultrasound with double-balloon endoscopy revealed a hypo-echoic layer corresponding to the muscularis propria, and a hyper-echoic layer corresponding to the fat tissue. These findings, which suggested that the tumor included areas outside the intestinal serosa, are not typical for a lipoma, despite the existence of a hyper-echoic layer corresponding to fatty tissue. We then considered a diagnosis of inverted Meckel’s diverticulum. Conclusion Lipoma and inverted Meckel’s diverticulum are difficult to differentially diagnose by computed tomography. Polypectomy is the preferred therapeutic approach when a lipoma is present; however, polypectomy in a patient with Meckel’s diverticulum requires full-thickness resection. Situations where polypectomy is performed without preparing for full-thickness resection can be avoided by first making a precise diagnosis using double-balloon endoscopy and endoscopic ultrasound.

2005-01-01

Klippel-Feil syndrome (KFS), a triad of short neck, limitation of neck movement and low posterior hairline, is characterized by the presence of congenitally fused cervical vertebrae and is often associated with multiple congenital anomalies. A 35-year-old male was referred for evaluation of an 'opaque hemithorax'. This led to a diagnosis of KFS, agenesis of left lung and gall bladder. The patient had history of wheezing dyspnea with nasal symptoms, which were diagnosed as asthma and allergic rhinitis. A high index of suspicion is required to recognize such a patient, and efforts should be made to seek other congenital anomalies. (author)

chloride secretion response, and ouabain, the Na+/K+-ATPase inhibitor, abolished most of the ISC. The transepithelial resistance (TER) of the diverticulum was much higher than the other tissues. Upon dissection, urate from ureteral urine was observed in the lower third of the colon and to a lesser extent......The structure and function of the lower intestinal tract of Rhea americana were characterized to evaluate the evolutionary relationship to other struthioniform and avian species. In 5 rheaqs the gross anatomy and the light and transmission electron microscopy were studied in parallel to in vitro...... large amounts of mucus. The proctodeal diverticulum was rich in lymphoid tissue arranged into lobuli bursales, and it was concluded that this structure is a modified bursa of Fabricius. The sparse interlobular epithelium of the diverticulum resembled that of colon and coprodeum. Baseline short circuit...

This event is rare at this age, and our patient is only the second 4-month-old infant reported in the English literature. The infant presented with painless frank rectal bleeding, the blood being maroon-colored, and clots were found in the diaper. There was also anemia, with an hemoglobin of less than 8 gm/dl. The color of the blood suggested a bleeding site in the ileocecal region, a Meckel’s diverticulum was suspected, which was then confirmed by an isotope scan. A typical Meckel’s diverticulum was found on laparoscopic surgery, was excised, and the infant made an uneventful recovery.

Technetium {sup 99m}Tc-pertechnetate is the most common and accurate noninvasive method of preoperative investigation for Meckel diverticulum. Despite introducing various methods to increase the sensitivity of the study, there are many case reports of false-negative Meckel scans. A repeat scan is sometimes requested in patients with a high suspicion for Meckel diverticulum and negative or equivocal first Meckel scan. The purpose of this retrospective study is to evaluate the value of repeat scintigraphy for these patients. Seven hundred fifty-three Meckel scans were recorded retrospectively. In 33 cases (22 male and 11 female; mean age: 6.8 years), the Meckel scintigraphy was repeated either due to a high clinical suspicion of Meckel diverticulum and a negative study (n = 21) or due to equivocal findings in the first scan (n = 12). The study was interpreted as positive if an abnormal focal activity was identified in the abdomen and pelvis during the procedure. The results were correlated with pathology and clinical symptoms. Seven out of 12 (58%) equivocal studies were positive on the second study. Six of them were proven to be positive at operation (confirmed by pathology) while one of them was negative on laparoscopy. From 21 negative first scans with a high suspicion for Meckel diverticulum, three (14%) were positive on the second study. All three were proven to be Meckel diverticulum on pathology. Repeat Meckel scans in patients with equivocal findings on the first study or a negative result with a high clinical suspicion for a Meckel diverticulum are useful especially in cases in which the first study had been done without appropriate preparation.

Phytobezoar in a jejunal diverticulum as a cause of small bowel obstruction: a case report

Directory of Open Access Journals (Sweden)

Rauf Fozia

2011-09-01

Full Text Available Abstract Introduction Phytobezoars are concretions of poorly digested fruit and vegetable fibers found in the alimentary tract. Previous gastric resection, gastrojejunostomy, or pyloroplasty predispose people to bezoar formation. Small-bowel bezoars normally come from the stomach, and primary small-bowel bezoars are very rare. They are seen only in patients with underlying small-bowel diseases such as diverticula, strictures, or tumors. Primary small-bowel bezoars almost always present as intestinal obstructions, although it is a very rare cause, being responsible for less than 3% of all small-bowel obstructions in one series. Jejunal diverticula are rare, with an incidence of less than 0.5%. They are usually asymptomatic pseudodiverticula of pulsion type, and complications are reported in 10% to 30% of patients. A phytobezoar in a jejunal diverticulum is an extremely rare presentation. Case presentation A 78-year-old Pakistani man presented to our clinic with small-bowel obstruction. Upon exploration, we found a primary small-bowel bezoar originating in a jejunal diverticulum and causing jejunal obstruction. Resection and anastomosis of the jejunal segment harboring the diverticulum was performed, and our patient had an uneventful recovery. Conclusion Primary small-bowel bezoars are very rare but must be kept in mind as a possible cause of small-bowel obstruction.

Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1-3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult. We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception. Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question "should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?"

Posteroseptal accessory pathways are often associated with coronary sinus diverticula. These diverticula contain myocardial coats which serve as a bypass tract. We report a 54-year-old woman who underwent radiofrequency (RF) catheter ablation for Wolff-Parkinson-White (WPW) syndrome. The surface electrocardiography (ECG) demonstrated pre-excitation, indicating a posteroseptal accessory pathway. A catheter ablation via a transaortic approach failed to ablate the accessory pathway. Coronary sinus venography revealed the presence of a diverticulum near the ostium. An electrogram in the neck of the diverticulum showed the coronary sinus myocardial extension potential, which was successfully ablated by delivery of RF energy. PMID:19949625

Primer small intestine bezoar is seen rarely. It frequently arises from underlying small intestine pathologies (diverticle, tumor, stricture etc.). We report a very rare case of disopyrobezoar in the duodenal diverticulum, a kind of phytobezoar caused by persimmons, which was treated laparoscopically. The 47-year-old patient applied to polyclinic with complaints of epigastric tenderness, occasional distension, and acid regurgitation. In endoscopical examination, impacted bezoar was determined in the diverticulum in the duodenum. Because it is too hard, it was unable to remove endoscopically. On the abdominal tomography, a smooth-bounded non-homogeneous mass including gas and soft tissue areas in the 2nd portion of the duodenum was detected. A barium meal confirmed the presence of a 5cm diameter diverticulum on the lateral wall of the second portion of the duodenum. It also showed an intraluminalfilling defect as well as the mottled appearance of the bezoar. Learned from history of the patient, that the patient consumed over persimmon in childhood. Generally, duodenal diverticles are asymptomatic. Surgical treatment is rarely necessary because of complications such as bleeding, perforation, abdominal pain, bezoar formation. As well as using methods such as gastric lavage, enzymatic dissolution, endoscopical fragmentation in the treatment of phytobezoar, their chances of success are low because its structure is rigid. Usually, surgical intervention is required. For the treatments of bezoar cases located in the small intestine, laparoscopic surgical method is a safe and feasible method in selected cases.

From a series of patients undergoing routine radiographic examination, 112 temporal bones with a high jugular fossa were selected. Among these, 43 jugular bulb diverticula were found. The structures affected by a high fossa or diverticulum were recorded and correlated to the clinical symptoms of the patient. The vestibule was suspected to be affected in five patients. Two of these patients had tinnitus and vertigo, and three had hearing loss. In one of the latter the hearing loss was most marked in the supine position. The cochlea was close to the fossa in three patients, all of whom had tinnitus. Four patients had a defect of the posterior semicircular canal. One of them lost his hearing after a severe fit of coughing, became unsteady and showed signs of a fistula. The internal acoustic meatus and the mastoid portion of the facial canal were affected in two and four patients, respectively, who had no recorded symptoms. Twelve of 34 patients with Meniere's disease and a high jugular fossa on the side of the diseased ear had a dehiscence of the vestibular aqueduct caused by the fossa or diverticulum, compared with nine of 58 patients in the unselected material. For comparison and demonstration of topographic relationships, 58 casts of unselected radiograhed temporal bone specimens with high jugular fossae or diverticula were investigated. In patients with a high jugular fossa or jugular bulb diverticulum, tomographic assessment may be of value. (orig.)

The right-side aortic arch may be associated with aberrant left subclavian artery, in some cases this artery originates from an aneurismal dilation of the aorta called Kommerell's diverticulum. A report is presented on 2 cases of vascular ring formed by a right-side aortic arch, anomalous left subclavian artery, Kommerell's diverticulum and left patent ductus arteriosus. A review the literature was also performed as regards the embryological development and the imaging methods used to help in the diagnosis of this rare vascular anomaly.

2008-07-01

An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

A Meckel's diverticulum is a remnant of the vitelline duct, which leads to the formation of a true diverticulum containing all layers of the small intestine. The diverticulum can contain ectopic gastric, duodenal or pancreatic tissue and is the most common congenital anomaly of the gastrointestin...... tract with estimates of prevalence ranging from 0.3% to 3%. The condition is usually clinically silent. In children the most common complication is gastrointestinal bleeding caused by ulceration due to the acid secretion by ectopic gastric mucosa....

Congenital cervical bronchogenic cyst: A case report

Directory of Open Access Journals (Sweden)

Kiralj Aleksandar

2015-01-01

Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

Bladder sensation measures and overactive bladder.

We performed a prospective multicomponent study to determine whether subjective and objective bladder sensation instruments may provide data on sensory dysfunction in patients with overactive bladder. We evaluated 70 prospectively enrolled patients with urodynamics and questionnaires on validated urgency (Urgency Perception Score), general overactive bladder (Urogenital Distress Inventory) and quality of life (Incontinence Impact Questionnaire). We first sought a correlation between sensory specific (Urgency Perception Score) and quality of life questionnaire scores. We then assessed a correlation between sensory questionnaire scores and urodynamic variables, exploring the hypothesis that certain urodynamic parameters may be bladder sensation measures. We evaluated 2 urodynamic derivatives (first sensation ratio and bladder urgency velocity) to increase sensory finding discrimination. We noted a moderate correlation between the Urgency Perception Score (0.56) and the Urogenital Distress Inventory (0.74) vs the Incontinence Impact Questionnaire (each p Perception Score and bladder capacity (-0.25, p sensation ratio and bladder urgency velocity statistically significantly correlated with the Urgency Perception Score despite the lesser or absent correlation associated with the individual components of these derivatives. Bladder sensation questionnaires may be valuable to identify patients with sensory dysfunction and provide additional data not obtained in generalized symptom questionnaires. Urodynamic variables correlated with bladder sensation questionnaire scores and may be an objective method to assess sensory dysfunction.

2008-01-01

Full Text Available Background/Aim. Meckel's diverticulum (MD is the most frequent anomaly of the small intestine. It appears after incomplete obliteration of the omphalomesenteric or viteline duct which normally obliterates and disappears by the 9th week of gestation. The majority of MD do not give rise to any clinical symptoms and are encounted either incidentally, at examination or intervention, or due to complications which may occur (obstruction, hemorrhagy, rupture, and are described in many clinical reports. The aim of the study was to find out the incidence of MD in fetuses when the development of the alimentary tract is already finished. Methods. The investigation was performed on 150 human fetuses of different sex and gastational age, using microdissection method. The cases with MD were photographed, described, their positions and dimensions were registered. The samples of MD taken for histological investigation were dyed with hematoksilin eosin method. Results. Meckel's diverticulum was found in five fetuses (three male and two female; in one case the fibrous band was found. All of them were located on animesenteric margine of the small intestine at the average distance of 92.5 mm from the ileocecal junction. They were of different shape and dimensions, but of the normal constitution of the small intestine. Conclusion. The incidence of MD was 3.3%, and 4% of all the anomalies of the intestines connected to the disappearance of the viteline duct. It was more frequent in the male, located on antimesenteric margine of the small intestine, at the destination which highly correlated to the age of the fetus. Meckel's diverticule were of different shapes and dimensions but of the typical constitution of the small intestine. .

Cancer arising from a female urethral diverticulum is rare, and because of its rarity, a review of the medical literature reveals significant nonuniformity in its management. We report an additional 2 cases of this disease, one of which has an even rarer feature of being mucin-producing. The management of our 2 cases is presented in detail and in line with the management of female urethral cancer. From our extensive literature search, diverticulectomy alone showed poor results with the highest rate of recurrence (67%). Extensive surgery, either in the form of cystourethrectomy or anterior exenteration, offered results comparable with those of combined therapy (diverticulectomy and full course of irradiation for early cases; preoperative irradiation followed by cystourethrectomy for late cases). Individualization of radiation treatment and cooperative effort between urologist and radiation oncologist are essential if best results are to be achieved

Karyotype analysis of a male exhibiting Meckel's diverticulum and aural atresia

Energy Technology Data Exchange (ETDEWEB)

Frizzell, B.; Hicks, M.F. (David Lipscomb Univ., Nashville, TN (United States))

Patau's Syndrome is caused by inheritance of an extra chromosome 13. It is characterized primarily by severe mental retardation, cleft palate, and retarded growth. Most fetuses expressing Patau's Syndrome spontaneously abort, and those that are born usually die before one year. Both Meckel's diverticulum and aural atresia are defects found in patients with Patau's at levels higher than those in the general population. An otherwise asymptomatic male expressing only Meckel's diverticulum and aural atresia has a female sibling whose son expressed Patau's syndrome. Twenty percent of patients with Patau's show a translocation of part of chromosome 13 to another D chromosome. If a translocation were the cause of the expression of Patau's in this family, it is possible that the normal male inherited a balanced translocation and the Patau's male received an unbalanced translocation. A karyotype analysis of the non-Patau's male was done to determine if such a translocation were present.

Congenital buried penis in the child is a congenital malformation where the penis appears small in size while all the parts of the organ are normal (the urethra, the erectile tissue and the glans penis). Our study aimed to describe our experience in the surgical treatment of this abnormality. We report the case of a 18-months old infant with bilateral hydrocele initially admitted to the Emergency Department and then referred to our Department. Clinical examination showed buried penis with tight foreskin and a dilation of the preputial reservoir due to urine. Surgical procedure included several steps: Z-shaped incision, pulling back of the foreskin of the penis, release of the adhesions surrounding the corpus cavernosum and ventral penile skin coverage using bladder catheter kept for a week to protect the wound healing. Aesthetic and functional result was satisfactory after 1-year follow-up. Congenital buried penis is a very debated subject in the literature. Our technique was simple and easily reproducible. Voiding difficulties and urinary infection are the main indications of this surgical procedure.

A 63-year-old woman with abdominal pain was referred to our hospital. Her pancreatic enzymes were elevated, and an abdominal computed tomography (CT) scan showed an enlarged pancreas, consistent with pancreatitis, and gas collection containing an impacted stone adjacent to Vater's papilla. This finding raised the suspicion of a duodenal diverticulum. A subsequent ERCP showed a juxtapapillary duodenal diverticulum (JPDD) filled with calculi and pus. The pancreatitis improved with 2 weeks of conservative treatment. Subsequently, the patient underwent resection of the uterus and bilateral adnexa to remove a large ovarian cyst that was also identified on the admission CT scan. On the third postoperative day, she developed abdominal pain and vomiting. CT revealed small bowel obstruction caused by an enterolith expelled from JPDD. Enterotomy was performed to remove the stone. To our knowledge, only three similar cases have been previously reported in Japan.

Leiomyoma of the urinary bladder is a rare benign mesenchymal tumour. We describe here a case of leiomyoma of the urinary bladder in a 65-year-old gentleman who presented with haematuria, passage of clots and combined obstructive and irritative urinary symptoms. The investigations revealed a vesical calculus and a mass on the left lateral wall of the urinary bladder. Cystolitholapaxy and transurethral resection of the tumour was performed. Histopathological report of the resected tumour revealed a leiomyoma of the urinary bladder. So far, a leiomyoma of the urinary bladder and a concomitant vesical calculus have not been described in literature. (author)

Full Text Available To obtain the basic data of congenital uronephropathy pattern and the affecting factors in children, we conducted a cross-sectional study at the Department of Child Health Cipto Mangunkusumo (CM Hospital Jakarta from 1995 to 1999 and 9 teaching hospitals throughout Indonesia. During the study period 134 patients were obtained, 116 patients from the CM Hospital and 18 patients from other teaching hospitals. Most patients (48.8% were below 1 year of age; male were affected more than female (2.4:1. The disorder was classified into two groups, i.e., congenital nephropathy and uropathy. There were 10 children with nephropathy, i.e., 4 with unilateral renal hypoplasia, 3 with polycystic kidney, and 3 with renal agenesis. In the uropathy group, 43 were with hypospadia, 22 with primary reflux vesicoureter, 18 with neurogenic bladder, and 17 with ureteropelvic junction obstruction. The complications found were urinary tract infection (71.2%, chronic renal failure (15.7%, hypertension (3.7%, and acute renal failure (1.5%. Consanguinity, familial disorders, maternal diseases, x-ray exposure and abortion efforts were found in a small proportion of patients. History of drug or herbs use in the first trimester of pregnancy was found in a large proportion of patients, mostly took analgesics (especially acetaminophen. In conclusion, uropathy disorders were much more common than congenital nephropathy. The most common complication was urinary tract infection, followed by chronic renal failure, hypertension, and acute renal failure.

Full Text Available We present a case of 2-year-old boy with long term dysuria and intermittent incontinence, and new onset of fever and headache. Significant past medical history includes congenital hydrocephalus with a ventriculoperitoneal shunt placement two years prior to consult. On physical examination, a tubular structure was noted underneath the prepuce suspected to be the distal tip of ventriculoperitoneal shunt, which was confirmed by kidney, ureter and bladder (KUB X-ray and CT scan. Patient was treated with a novel approach of extraperitoneal removal of ventriculoperitoneal shunt distal tip with cystorrhaphy via a low transverse pfannenstiel incision, separate left ventriculostomy tube insertion and complete removal of ventriculoperitoneal shunt from the right ventricle. This report accounts a rare pediatric case with ventriculoperitoneal shunt perforation into a normal bladder successfully treated with mini-open surgery.

Daniel Cabezalí Barbancho

2013-01-01

Full Text Available Spontaneous bladder perforation is an uncommon event in childhood. It is usually associated with bladder augmentation. We are presenting a case of bladder rupture in an infant with neurogenic bladder without prior bladder surgery. Three days after lipomyelomeningocele excision the patient showed signs and symptoms of acute abdomen. The ultrasound exploration revealed significant amount of intraperitoneal free fluid and therefore a laparoscopic exploration was performed. A posterior bladder rupture was diagnosed and repaired laparoscopically. Currently, being 3 years old, she keeps successfully dry with clean intermittent catheterization. Neurogenic bladder voiding function can change at any time of its evolution and lead to complications. Early diagnosis of spontaneous bladder rupture is of paramount importance, so it is essential to think about it in the differential diagnosis of acute abdomen.

OBJECTIVE: Most researchers believe that the presence of large epiphrenic diverticulum (ED) with severe symptoms should lead to the consideration of surgical options. The choice of minimally invasive techniques and whether Heller myotomy with antireflux fundoplication should be employed after diverticulectomy became points of debate. The aim of this study was to describe how to perform laparoscopic transhiatal diverticulectomy (LTD) and oesophagomyotomy with the aid of intraoperative gastroin...

International Nuclear Information System (INIS)

Majewski, Wojciech; Wesolowska, Iwona; Urbanczyk, Hubert; Hawrylewicz, Leszek; Schwierczok, Barbara; Miszczyk, Leszek

2009-01-01

Purpose: To estimate bladder movements and changes in dose distribution in the bladder and surrounding tissues associated with changes in bladder filling and to estimate the internal treatment margins. Methods and Materials: A total of 16 patients with bladder cancer underwent planning computed tomography scans with 80- and 150-mL bladder volumes. The bladder displacements associated with the change in volume were measured. Each patient had treatment plans constructed for a 'partially empty' (80 mL) and a 'partially full' (150 mL) bladder. An additional plan was constructed for tumor irradiation alone. A subsequent 9 patients underwent sequential weekly computed tomography scanning during radiotherapy to verify the bladder movements and estimate the internal margins. Results: Bladder movements were mainly observed cranially, and the estimated internal margins were nonuniform and largest (>2 cm) anteriorly and cranially. The dose distribution in the bladder worsened if the bladder increased in volume: 70% of patients (11 of 16) would have had bladder underdosed to 70%, 80%, and 90% of the prescribed dose was 23%, 20%, and 15% for the rectum and 162, 144, 123 cm 3 for the intestines, respectively) than with a 'partially full' bladder (volume that received >70%, 80%, and 90% of the prescribed dose was 28%, 24%, and 18% for the rectum and 180, 158, 136 cm 3 for the intestines, respectively). The change in bladder filling during RT was significant for the dose distribution in the intestines. Tumor irradiation alone was significantly better than whole bladder irradiation in terms of organ sparing. Conclusion: The displacements of the bladder due to volume changes were mainly related to the upper wall. The internal margins should be nonuniform, with the largest margins cranially and anteriorly. The changes in bladder filling during RT could influence the dose distribution in the bladder and intestines. The dose distribution in the rectum and bowel was slightly better with

Full Text Available Purpose: Anterior urethral valves (AUV is an unusual cause of congenital obstruction of the male urethra, being 15 to 30 times less common than posterior urethral valves (PUV. It has been suggested that patients with congenital anterior urethral obstruction have a better prognosis than those with PUV.The long term prognosis of anterior urethral valves is not clear in the literature. In this report we describe our experience and long-term follow up of patients with AUV.Materials and methods: We retrospectively identified 13 patients who presented with the diagnosis of AUV in our institutions between 1994 and 2012. From the 11 patients included, we evaluated the gestational age, ultrasound and voiding cystourethrogram findings, age upon valve ablation, micturition pattern, creatinine and clinical follow up.Results: Between 1994 and 2012 we evaluated 150 patients with the diagnosis of urethral valves, where 11 patients (7.3% had AUV and an adequate follow up. Mean follow up is 6.3 years. 5 patients (45.4% had pre-natal diagnosis of AUV. The most common prenatal ultrasonographic finding was bilateral hydronephrosis and distended bladder.The mean gestational age was 37.6 weeks. Postnatally, 90% had trabeculated bladder, 80% hydronephrosis and 40% renal dysplasia. The most common clinical presentation was urinary tract infection in 5 patients (45.4%.7 patients (63.6% had primary transurethral valve resection or laser ablation and 3 patients (27.2% had primary vesicostomies. One boy (9.1% had urethrostomy with urethral diverticulum excision. 2 patients (18.2% developed end-stage renal disease (ESRD.Conclusions: Early urinary tract obstruction resulted in ESRD in 18% of our patient population. In our series, the complication rate and the evolution to renal failure are high and similar to patients with PUV. In patients with AUV we recommend long-term follow up and close evaluation of patient’s bladder and renal function.

Wireless Capsule Endoscopy Detects Meckel’s Diverticulum in a Child with Unexplained Intestinal Blood Loss

Full Text Available Meckel’s diverticulum (MD is the most common congenital anomaly of the gastrointestinal (GI tract, affecting about 2% of the population. Most cases of Meckel’s diverticula are asymptomatic. The diagnosis of symptomatic MD is often difficult to make. We report the case of an 8-year-old boy who presented with GI bleeding due to MD. The diagnostic difficulties after an initial negative endoscopic evaluation and the diagnostic value of the various endoscopic procedures are discussed. The patient had suffered from bright red stools for 20 h before hospital admission. GI scintigraphy with 99mTc-Na-pertechnetate was negative for heterotopic gastric tissue in the small bowel area. Colonoscopy performed in order to exclude Crohn’s disease was also negative. He was placed on ranitidine at a dose of 6 mg/kg body weight twice daily. The patient remained asymptomatic over a period of 6 months before he was readmitted due to macroscopic rectal bleeding. Upper endoscopy and colonoscopy used to investigate the source of bleeding showed normal macroscopic findings. Radiolabeling of blood constituents with 99mTc on delayed imaging showed radionucleotide concentration in the ascending and transverse colon suggestive of a lesion in the ileocecal area. Further investigation with the use of wireless capsule endoscopy revealed a MD. Wireless capsule endoscopy may thus be indicated for patients with GI blood loss when other diagnostic methods, such as upper and lower endoscopy and colonoscopy, have failed to identify the source of bleeding.

Portable bladder ultrasound: an evidence-based analysis.

Science.gov (United States)

2006-01-01

The aim of this review was to assess the clinical utility of portable bladder ultrasound. TARGET POPULATION AND CONDITION Data from the National Population Health Survey indicate prevalence rates of urinary incontinence are 2.5% in women and 1.4 % in men in the general population. Prevalence of urinary incontinence is higher in women than men and prevalence increases with age. Identified risk factors for urinary incontinence include female gender, increasing age, urinary tract infections (UTI), poor mobility, dementia, smoking, obesity, consuming alcohol and caffeine beverages, physical activity, pregnancy, childbirth, forceps and vacuum-assisted births, episiotomy, abdominal resection for colorectal cancer, and hormone replacement therapy. For the purposes of this review, incontinence populations will be stratified into the following; the elderly, urology patients, postoperative patients, rehabilitation settings, and neurogenic bladder populations. Urinary incontinence is defined as any involuntary leakage of urine. Incontinence can be classified into diagnostic clinical types that are useful in planning evaluation and treatment. The major types of incontinence are stress (physical exertion), urge (overactive bladder), mixed (combined urge and stress urinary incontinence), reflex (neurological impairment of the central nervous system), overflow (leakage due to full bladder), continuous (urinary tract abnormalities), congenital incontinence, and transient incontinence (temporary incontinence). Postvoid residual (PVR) urine volume, which is the amount of urine in the bladder immediately after urination, represents an important component in continence assessment and bladder management to provide quantitative feedback to the patient and continence care team regarding the effectiveness of the voiding technique. Although there is no standardized definition of normal PVR urine volume, measurements greater than 100 mL to 150 mL are considered an indication for urinary

Wen-Ching Weng

2013-08-01

Full Text Available Primary malignancies of female urethral diverticulum are rare. A well-documented female patient with primary clear cell carcinoma of the urethral diverticulum is presented here. A 65-year-old woman presented with frequency and voiding difficulty for 2 months. Physical examination showed a 4-cm mass protruding from anterior vaginal wall. Intravenous urography, magnetic resonance imaging, and cystoscopy showed a polypoid mass in urethral diverticulum. She then underwent anterior exenteration with ileal conduit diversion and urethrectomy. Pathology confirmed the diagnosis of clear cell adenocarcinoma with bladder neck invasion. She had no disease recurrence at 2-year follow-up. Careful clinical examination and image studies are helpful in making the preoperative diagnosis for the rare disease. Early radical surgery can achieve better survival.

Bladder and renal calculi after bladder augmentation are thought to be primarily infectious, yet few studies have reported stone composition. The primary aim was to assess bladder stone composition after augmentation, and renal stone composition in those with subsequent nephrolithiasis. The exploratory secondary aim was to screen for possible risk factors for developing infectious stones. Patients treated for bladder stones after bladder augmentation at the present institution between 1981 and 2012 were retrospectively reviewed. Data were collected on demographics, surgeries and stone composition. Patients without stone analysis were excluded. Stones containing struvite, carbonate apatite or ammonium acid ureate were classified as infectious. The following variables were analyzed for a possible association with infectious bladder stone composition: gender, history of cloacal exstrophy, ambulatory status, nephrolithiasis, recurrent urea-splitting urinary tract infections, first vs recurrent stones, timing of presentation with a calculus, history of bladder neck procedures, catheterizable channel and vesicoureteral reflux. Fisher's exact test was used for analysis. Of the 107 patients with bladder stones after bladder augmentation, 85 met inclusion criteria. Median age at augmentation was 8.0 years (follow-up 10.8 years). Forty-four patients (51.8%) recurred (14 multiple recurrences, 143 bladder stones). Renal calculi developed in 19 (22.4%) patients with a bladder stone, and 10 (52.6%) recurred (30 renal stones). Overall, 30.8% of bladder stones were non-infectious (Table). Among patients recurring after an infectious bladder stone, 30.4% recurred with a non-infectious one. Among patients recurring after a non-infectious stone, 84.6% recurred with a non-infectious one (P = 0.005). Compared with bladder stones, renal stones were more likely to be non-infectious (60.0%, P = 0.003). Of patients with recurrent renal calculi after an infectious stone, 40.0% recurred with

One in 5 recently deployed US women veterans report overactive bladder symptoms. Mental health conditions such as depression and anxiety commonly co-occur in women with overactive bladder, but temporal relationships between these outcomes have not been well studied, and the mechanism behind this association is unknown. The Women Veterans Urinary Health Study, a nationwide longitudinal study in recently deployed women veterans, was designed to better understand relationships between overactive bladder and mental health conditions. We sought to estimate the 1-year incidence and remission of overactive bladder and to identify the impact of depression, anxiety, posttraumatic stress disorder, and prior sexual assault on 1-year overactive bladder incidence and remission rates. Participants of this 1-year prospective cohort study were female veterans separated from military service who had returned from Iraq or Afghanistan deployment within the previous 2 years. Eligible women were identified through the Defense Manpower Data Center and recruited by mail and telephone. Telephone screening confirmed participants were ambulatory, community-dwelling veterans and excluded those with urinary tract fistula, congenital abnormality, or cancer; pelvic radiation; spinal cord injury; multiple sclerosis; Parkinson disease; stroke; or current/recent pregnancy. Data collection included computer-assisted telephone interviews performed at enrollment and 1 year later. The interview assessed demographic and military service characteristics; urinary symptoms and treatment; depression, anxiety, and posttraumatic stress disorder symptoms and treatment; and a lifetime history of sexual assault. Overactive bladder was identified if at least moderately bothersome urgency urinary incontinence and/or urinary frequency symptoms were reported on Urogenital Distress Inventory items. Exposures included depression, anxiety, posttraumatic stress disorder, and lifetime sexual assault, assessed at

Since the use of antibiotics, bladder necrosis has become a rare condition. We report a case of bladder necrosis in a 90-year-old man following urinary retention. After insertion of a transurethral catheter (TUC), 2 L of urine was evacuated. In the following days, the TUC became intermittently blocked. Adequate bladder drainage could not be obtained despite intensive rinsing and placement of a suprapubic catheter. On surgical exploration necrosis of almost the entire bladder wall, except for the trigone, was encountered. Surgical debridement of the non-viable bladder wall without opening the abdominal cavity was conducted, and a TUC was placed in the Retzius cavity to ensure evacuation of urine. Since the patient was haemodynamically unstable, construction of a urinary diversion was waived and urinary drainage of the Retzius cavity by the TUC was accepted, resulting in adequate urinary drainage without compromising renal function. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Urinary retention and micturition disorders after overdistension are clinically well-known complications of subvesical obstruction. We attempted to evaluate whether bladder overdistension influences bladder response and whether overdistension supports detrusor decompensation. Following lumbal laminectomy in 9 male foxhounds, the sacral anterior roots S2 and S3 were placed into a modified Brindley electrode for reproducible and controlled detrusor activation. The bladder was filled in stages of 50 ml from 0 to 700 ml, corresponding to an overdistension. At each volume, the bladder response during sacral anterior root stimulation was registered. After overdistension, the bladder was refilled stepwise from 0 to 300 ml and stimulated. In all dogs, the bladder response was influenced by the intravesical volume. The maximum pressure (mean 69.1 cm H(2)O) was observed at mean volume of 100 ml. During overdistension, a significant reduction in bladder response of more than 80% was seen. After overdistension, a significant reduction in intravesical pressure of 19.0% was observed. In 2 cases, reduction in bladder response was more than 50% after a single overdistension. We conclude that motoric bladder function is influenced during and after overdistension. A single bladder overdistension can support acute and long-lasting detrusor decompensation. In order to protect motoric bladder function, bladder overdistension must be prevented.

Effects of a high jugular fossa and jugular bulb diverticulum on the inner ear. A clinical and radiologic investigation

Energy Technology Data Exchange (ETDEWEB)

Wadin, K.; Thomander, L.; Wilbrand, H.

From a series of patients undergoing routine radiographic examination, 112 temporal bones with a high jugular fossa were selected. Among these, 43 jugular bulb diverticula were found. The structures affected by a high fossa or diverticulum were recorded and correlated to the clinical symptoms of the patient. The vestibule was suspected to be affected in five patients. Two of these patients had tinnitus and vertigo, and three had hearing loss. In one of the latter the hearing loss was most marked in the supine position. The cochlea was close to the fossa in three patients, all of whom had tinnitus. Four patients had a defect of the posterior semicircular canal. One of them lost his hearing after a severe fit of coughing, became unsteady and showed signs of a fistula. The internal acoustic meatus and the mastoid portion of the facial canal were affected in two and four patients, respectively, who had no recorded symptoms. Twelve of 34 patients with Meniere's disease and a high jugular fossa on the side of the diseased ear had a dehiscence of the vestibular aqueduct caused by the fossa or diverticulum, compared with nine of 58 patients in the unselected material. For comparison and demonstration of topographic relationships, 58 casts of unselected radiograhed temporal bone specimens with high jugular fossae or diverticula were investigated. In patients with a high jugular fossa or jugular bulb diverticulum, tomographic assessment may be of value.

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

2005-05-01

Endoscopic diverticulotomy is rapidly becoming the procedure of choice for treatment of Zenker's diverticulum. The endoscopic approach has resulted in significant decreases in patient morbidity, time to resumption of oral intake, and overall cost as compared with open treatment. However, a small but significant patient population is unable to accommodate the rigid laryngoscope and therefore requires open treatment. We present a novel technique, flexible fiberoptic endoscopic-assisted diverticulotomy, for the management of patients who are unable to undergo rigid endoscopy.

2012-01-01

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)

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

Leiomyoma of the bladder is a very rare disorder that accounts for 0.43% of all bladder neoplasms. Although the pathophysiology of the bladder leiomyoma is unknown, there are some theories in it. The patients can be asymptomatic; and clinical symptoms, when present, are associated with the tumor size and location. Imaging techniques such as ultrasonography, intravenous urography, computed tomography, and magnetic resonance imaging are helpful but definitive diagnosis is made by histopathological examination. Surgical resection of tumor with transurethral, open, laparoscopic and robotic approaches is the main treatment. We present a case of leiomyoma of the bladder in an adult male patient.

Conclusion: There are obvious differences in bladder CT scans of patients with symptoms of bladder pain due to different etiology. Increased BWT was associated with increased pain scores and decreased bladder capacity in patients with KC and IC. BWT on a CT scan might be considered a marker for the severity of bladder inflammation.

Full Text Available The success of the initial closure of the complex bladder-exstrophy remains a challenge in pediatric surgery. This study describes a personal experience of the causes of failure of the initial closure and operative morbidity during the surgical treatment of bladder-exstrophy complex. From April 2000 to March 2014, four patients aged 16 days to 7 years and 5 months underwent complex exstrophy-epispadias repair with pelvic osteotomies. There were three males and one female. Three of them had posterior pelvic osteotomy, one had anterior innominate osteotomy. Bladder Closure: Bladder closure was performed in three layers. Our first patient had initial bladder closure with polyglactin 4/0 (Vicryl ® 4/0, concerning the last three patients, initial bladder closure was performed with polydioxanone 4/0 (PDS ® 4/0. The bladder was repaired leaving the urethral stent and ureteral stents for full urinary drainage for three patients. In one case, only urethral stent was left, ureteral drainage was not possible, because stents sizes were more important than the ureteral diameter. Out of a total of four patients, initial bladder closure was completely achieved for three patients. At the immediate postoperative follow-up, two patients presented a complete disunion of the abdominal wall and bladder despite an appropriate postoperative care. The absorbable braided silk (polyglactin used for the bladder closure was considered as the main factor in the failure of the bladder closure. The second cause of failure of the initial bladder closure was the incomplete urine drainage, ureteral catheterisation was not possible because the catheters sizes were too large compared with the diameters of the ureters. The failure of the initial bladder-exstrophy closure may be reduced by a closure with an absorbable monofilament silk and efficient urine drainage via ureteral catheterisation.

Ruptured Jejunal Diverticulum Due to a Single-Band Small Bowel Obstruction

Full Text Available Jejunal diverticulosis is rare and often goes unnoticed until complications occur. The diverticula are true, acquired diverticula and often asymptomatic. Jejunal diverticulosis can be associated with diverticulosis of the duodenum, ileum, and colon. Here we describe a patient with known severe diverticular disease of the large bowel, who presented acutely with abdominal pain and signs of generalised peritonitis. Laparotomy showed ruptured jejunal diverticulosis with a single band over the terminal ileum, causing small bowel obstruction. Spontaneous perforation of a jejunal diverticulum is rare and is usually an intraoperative finding. One should exclude a precipitating cause, such as coexisting distal obstruction, stricture, or a foreign body.

A Right-sided Aortic Arch with Kommerell's Diverticulum of the Aberrant Left Subclavian Artery Presenting with Syncope

Full Text Available A right-sided aortic arch with an aneurysm of the aberrant subclavian artery is a rare disease. We report a case of Kommerell's diverticulum of an aberrant left subclavian artery in a patient with a right-sided aortic arch. Fewer than 50 cases have been reported in the literature. A number of operative strategies are described. Right thoracotomy provides good exposure and avoids the morbidity associated with bilateral thoracotomy or sternotomy and thoracotomy. In our patient with symptoms of dysphagia, syncope, and left subclavian steal syndrome, a left thoracotomy was used. The repair was accomplished by division of a left ligamentum arteriosum, obliteration of the Kommerell's aneurysm, and an aorto-subclavian bypass. Postoperative complications included left vocal cord palsy and Horner's syndrome. Hoarseness and left ptosis recovered spontaneously 3 months after surgery, and the patient remained symptom-free at the 1-year follow-up. We believe a left thoracotomy for direct repair of Kommerell's diverticulum is a simple and safe method without the increased morbidity found in other procedures.

Meckel's diverticulum (MD) is a common congenital anomaly caused by failure of involution of the omphalomesenteric duct. Enthusiasm for minimally invasive surgery (MIS) in children has burgeoned as technologies have advanced, but the outcomes of laparoscopic resection in comparison to open laparotomy for MD remain poorly defined. We queried a large national database to compare current practice patterns and clinical outcomes between surgical approaches for MD in the pediatric population. The National Surgical Quality Improvement Program-Pediatric (NSQIP-Ped) database was queried for patients undergoing surgical intervention for MD (2011-2014). Patients were stratified by surgical approach. Baseline characteristics, intraoperative variables, and perioperative complications were compared by univariate analysis using Pearson's χ 2 test for categorical variables and Kruskall-Wallis test for continuous variables. Primary outcomes of interest were length of stay (LOS), rate of readmission, and 30-day mortality. Secondary outcomes included operative time, anesthesia time, postoperative complications, and rates of reoperation. A total of 148 cases of MD were identified, of which 73 (49.3%) were initially managed with a laparoscopic approach and 75 (50.7%) were managed with an open approach. We found a high rate of conversion from laparoscopy to an open approach (20/73 or 27.4%). The median age of the laparoscopic group was higher than the open group (8.3 vs. 2.5years, p0.05). Nearly half of all resections for MD in children are now approached laparoscopically. This approach has equivalent outcomes to traditional open laparotomy. More widespread use of a hybrid approach with laparoscopy and exteriorization of the small bowel through an extended port site may facilitate avoiding open laparotomy. Routine conversion to open for palpation of the MD or segmental small bowel resection should be avoided in the absence of compelling intra-operative findings or operative

2013-06-01

Full Text Available Purpose: Bladder wall thickness has been reported to be associated with overactive bladder (OAB in women. Diabetic women have an increased risk for OAB syndrome and may have an increased risk for bladder wall thickness. Methods: A total of 235 female patients aged 40 to 75 years were categorized into four groups. The first group consisted of women free of urgency or urge urinary incontinence. The second group included nondiabetic women with idiopathic OAB. The third group consisted of women with diabetes and clinical OAB, and women with diabetes but without OAB constituted the fourth group. Bladder wall thickness at the anterior wall was measured by ultrasound by the suprapubic approach with bladder filling over 250 mL. Results: The diabetic (third group and nondiabetic (second group women with OAB had significantly greater bladder wall thickness at the anterior bladder wall than did the controls. However, the difference was not significant between the diabetic (third group and the nondiabetic (second group women with OAB. Women with diabetes but without OAB (fourth group had greater bladder wall thickness than did the controls but this difference was not significant. Additionally, the difference in bladder wall thickness between diabetic women with (third group and without (fourth group OAB was not significant. Conclusions: This is the first study to show that bladder wall thickness is increased in diabetic women with and without OAB. Additionally, nondiabetic women with OAB had increased bladder wall thickness. Further studies may provide additional information for diabetic and nondiabetic women with OAB, in whom the etiopathogenesis of the disease may be similar.

Membrane-like structure in the urinary bladder neck of a young cat: diagnosis and treatment using balloon dilatation and a balloon-expandable metallic stent

Directory of Open Access Journals (Sweden)

Matias Ruiz-Drebing

2017-10-01

Full Text Available Case summary A 33-month-old, spayed female domestic shorthair cat was referred to the Animal Health Trust for the investigation of urinary incontinence and straining to urinate. A membrane-like structure was detected in the bladder neck, which caused partial obstruction of the urinary bladder. A combination of different imaging techniques, including ultrasonography, radiography, CT and fluoroscopy, was essential in the diagnosis, surgical planning and treatment of this intravesicular stricture. During retrograde vaginourethrocystogram, unexpected subcapsular accumulation of contrast medium was seen around both kidneys on radiographs and confirmed with CT. Three different treatments were performed, including surgical debridement, balloon dilatation and placement of a self-expanding metallic stent across the stricture. Histopathology of the membrane was unable to differentiate whether the lesion was congenital or acquired. No urinary incontinence was observed 5 months after placement of the metallic stent. Relevance and novel information This is the first reported case using fluoroscopic-guided balloon dilatation of the bladder neck for the treatment of a bladder neck stricture. Presence of renal subcapsular contrast medium secondary to a retrograde vaginourethrocystogram due to partial obstruction at the bladder neck in a cat has not been previously described.

Interstitial cystitis and bladder pain syndrome are terms used to describe a heterogeneous chronic pelvic and bladder pain disorder. Despite its significant prevalence, our understanding of disease etiology is poor. We molecularly characterized interstitial cystitis/bladder pain syndrome and determined whether there are clinical factors that correlate with gene expression. Bladder biopsies from female subjects with interstitial cystitis/bladder pain syndrome and female controls without signs of the disease were collected and divided into those with normal and low anesthetized bladder capacity, respectively. Samples then underwent RNA extraction and microarray assay. Data generated by these assays were analyzed using Omics Explorer (Qlucore, Lund, Sweden), GeneSifter® Analysis Edition 4.0 and Ingenuity® Pathway Analysis to determine similarity among samples within and between groups, and measure differentially expressed transcripts unique to each phenotype. A total of 16 subjects were included in study. Principal component analysis and unsupervised hierarchical clustering showed clear separation between gene expression in tissues from subjects with low compared to normal bladder capacity. Gene expression in tissue from patients with interstitial cystitis/bladder pain syndrome who had normal bladder capacity did not significantly differ from that in controls without interstitial cystitis/bladder pain syndrome. Pairwise analysis revealed that pathways related to inflammatory and immune response were most involved. Microarray analysis provides insight into the potential pathological condition underlying interstitial cystitis/bladder pain syndrome. This pilot study shows that patients with this disorder who have low compared to normal bladder capacity have significantly different molecular characteristics, which may reflect a difference in disease pathophysiology.

In contrast to the inconsistent results of organic causes, it has been found that psychological risk factors are reliably related to functional somatic syndromes (FSSs), including interstitial cystitis/bladder pain syndrome (IC/BPS). Compared to patients with acute cystitis, a subgroup of IC/BPS patients with a history of childhood relational trauma reported intensified unregulated affective states (i.e., anxiety and depression) and trauma-related psychopathology (i.e., dissociation). Nevertheless, it remains unknown whether psychosocial risk factors can be separated from bladder-centric factors. This study aimed to verify whether psychosocial factors such as alexithymia, which is a key psychological factor of FSSs, are less likely to be linked to a low bladder capacity in patients with IC/BPS. Ninety-four female IC/BPS patients were recruited from the outpatient departments of urology, obstetrics, and gynecology. Anxiety, depression, dissociation, childhood relational trauma, and alexithymia were assessed using standardized scales, and anesthetic bladder capacity was examined by cystoscopic hydrodistention. Positive correlations were found between anesthetic bladder capacity and the psychosocial variables, including alexithymia. An increased bladder capacity was associated with anxiety, dissociation, and childhood relational trauma, and a combination of high cognitive and low affective alexithymia mediated the correlations between bladder capacity and the psychosocial variables. Psychosocial variables that are associated with an aversive childhood relational environment and affect dysregulation may constitute a pathogenic trajectory that differs from bladder-centric defects such as a lower bladder capacity. The findings of this study support the notion that IC/BPS in some patients may be due to an FSS. Copyright © 2017 Elsevier Inc. All rights reserved.

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

The standard treatment for muscle-invasive bladder cancer is surgical removal of the bladder and construction of a neobladder. Recently, important improvements have been made in the potential for bladder-conserving treatment using radiotherapy. External beam radiotherapy has undergone technological improvements, as a result of which it is possible to radiate the tumour more precisely while decreasing radiation to healthy tissue. Radiochemotherapy improves local recurrence-free and overall survival compared with radiotherapy alone. The results of this combined treatment are comparable with those of surgery. Additionally, Dutch radiotherapy departments have collected data in a national database of 1040 selected patients with confined bladder cancer. These patients were treated with external beam radiation, limited surgery and brachytherapy. The 5-year local recurrence-free survival was 75%. Bladder conserving treatment options for muscle-invasive bladder cancer should be discussed during the multidisciplinary meeting.

Background and purpose: Varying bladder fillings during radiotherapy lead to a changing dose-volume load to the bladder and adjacent structures. The aim of the study was to compare the extent of bladder wall movements during parallel series with full bladder (FB) and empty bladder (EB). Materials and methods: Three hundred and forty serial computed tomography (CT) scans were performed in 50 patients scheduled for primary and postoperative radiotherapy for prostate cancer. Each patient underwent two CT scans (with FB and EB) before and 2-3 times during radiotherapy. Displacements of the bladder wall were compared and correlated with changing bladder fillings. Results: The variability of FB was larger compared to EB volume (standard deviation of 124cc and 56cc; p < 0.01), but significant bladder wall displacement variabilities were only found at the anterior and superior borders. Within a bladder volume range between -100 and +200 ml relative to the FB planning scan, the mean bladder wall displacement remained <5 mm at the inferior, lateral, and posterior borders - as opposed to 15 and 21 mm at the anterior and superior borders. Conclusions: Treating the pelvis with EB compared to FB, bladder wall displacement can be only reduced at the superior and anterior borders. FB wall displacements are comparable with EB displacements at all other borders

Congenital bladder exstrophy associated with Duogynon hormonal pregnancy tests-signal for teratogenicity or consumer report bias?

Tümmler, Gregor; Rißmann, Anke; Meister, Reinhard; Schaefer, Christof

2014-06-01

A combination of ethinylestradiol and 10mg norethisterone under the brand names of Duogynon (Germany) or Primodos (UK) was used as a pregnancy test until the 1970s. Until very recently there was continuing public concern about the safety of these drugs and legal proceedings were instituted against the medicinal authorization holder. Given the lack of epidemiological studies focusing on Duogynon/Primodos, the present study evaluates 296 consumer reports of the German Duogynon database and compares the reported birth defects with data from a population based birth registry. The most striking result is an increase of bladder exstrophy (OR=37.27; 95%-CI 14.56-95.28). Neural tube defects (OR=2.99; 95%-CI 1.85-4.84) and renal agenesis (OR=2.53; 95%-CI 1.17-5.45) were also significantly increased. Bladder exstrophy may be a yet undetected teratogenic effect of Duogynon, but may also represent a reporting bias. The present study highlights the difficulties of evaluating consumer reports which may be influenced by public media. Copyright © 2013 Elsevier Inc. All rights reserved.

Objective Catheterization to measure bladder sensitivity is aversive and hinders human participation in visceral sensory research. Therefore, we sought to characterize the reliability of sonographically-estimated female bladder sensory thresholds. To demonstrate this technique’s usefulness, we examined the effects of self-reported dysmenorrhea on bladder pain thresholds. Methods Bladder sensory threshold volumes were determined during provoked natural diuresis in 49 healthy women (mean age 24 ± 8) using three-dimensional ultrasound. Cystometric thresholds (Vfs – first sensation, Vfu – first urge, Vmt – maximum tolerance) were quantified and related to bladder urgency and pain. We estimated reliability (one-week retest and interrater). Self-reported menstrual pain was examined in relationship to bladder pain, urgency and volume thresholds. Results Average bladder sensory thresholds (mLs) were Vfs (160±100), Vfu (310±130), and Vmt (500±180). Interrater reliability ranged from 0.97–0.99. One-week retest reliability was Vmt = 0.76 (95% CI 0.64–0.88), Vfs = 0.62 (95% CI 0.44–0.80), and Vfu = 0.63, (95% CI 0.47–0.80). Bladder filling rate correlated with all thresholds (r = 0.53–0.64, p dysmenorrhea pain had increased bladder pain and urgency at Vfs and increased pain at Vfu (p’s dysmenorrhea pain was unrelated to bladder capacity. Discussion Sonographic estimates of bladder sensory thresholds were reproducible and reliable. In these healthy volunteers, dysmenorrhea was associated with increased bladder pain and urgency during filling but unrelated to capacity. Plausibly, dysmenorrhea sufferers may exhibit enhanced visceral mechanosensitivity, increasing their risk to develop chronic bladder pain syndromes. PMID:23370073

Radical cystectomy plus urinary diversion, the reference standard treatment for muscle-invasive bladder cancer, associates with high complication rates and compromises quality of life as a result of long-term effects on urinary, gastrointestinal and sexual function, and changes in body image. As a society ages, the number of elderly patients unfit for radical cystectomy as a result of comorbidity will increase, and thus the demand for bladder-sparing approaches for muscle-invasive bladder cancer will also inevitably increase. Trimodality bladder-sparing approaches consisting of transurethral resection, chemotherapy and radiotherapy (Σ55-65 Gy) yield overall survival rates comparable with those of radical cystectomy series (50-70% at 5 years), while preserving the native bladder in 40-60% of muscle-invasive bladder cancer patients, contributing to an improvement in quality of life for such patients. Limitations of the trimodality therapy include muscle-invasive bladder cancer recurrence in the preserved bladder, which most often arises in the original muscle-invasive bladder cancer site; potential lack of curative intervention for regional lymph nodes; and increased morbidity in the event of salvage radical cystectomy for remaining or recurrent disease as a result of high-dose pelvic irradiation. Consolidative partial cystectomy with pelvic lymph node dissection followed by induction chemoradiotherapy at lower dose (exempli gratia (e.g.) 40 Gy) is a rational strategy for overcoming such limitations by strengthening locoregional control and reducing radiation dosage. Molecular profiling of the tumor and functional imaging might play important roles in optimal patient selection for bladder preservation. Refinement of radiation techniques, intensified concurrent or adjuvant chemotherapy, and novel sensitizers, including molecular targeting agent, are also expected to improve outcomes and consequently provide more muscle-invasive bladder cancer patients with favorable

Purpose: To quantify daily bladder size and position variations during bladder cancer radiotherapy. Methods and Materials: Ten bladder cancer patients underwent daily cone beam CT (CBCT) imaging of the bladder during radiotherapy. Bladder and planning target volumes (bladder/PTV) from CBCT and planning CT scans were compared with respect to bladder center-of-mass shifts in the x (lateral), y (anterior-posterior), and z (superior-inferior) coordinates, bladder/PTV size, bladder/PTV margin positions, overlapping areas, and mutually exclusive regions. Results: A total of 262 CBCT images were obtained from 10 bladder cancer patients. Bladder center of mass shifted most in the y coordinate (mean, -0.32 cm). The anterior bladder wall shifted the most (mean, -0.58 cm). Mean ratios of CBCT-derived bladder and PTV volumes to planning CT-derived counterparts were 0.83 and 0.88. The mean CBCT-derived bladder volume (± standard deviation [SD]) outside the planning CT counterpart was 29.24 cm 3 (SD, 29.71 cm 3 ). The mean planning CT-derived bladder volume outside the CBCT counterpart was 47.74 cm 3 (SD, 21.64 cm 3 ). The mean CBCT PTV outside the planning CT-derived PTV was 47.35 cm 3 (SD, 36.51 cm 3 ). The mean planning CT-derived PTV outside the CBCT-derived PTV was 93.16 cm 3 (SD, 50.21). The mean CBCT-derived bladder volume outside the planning PTV was 2.41 cm 3 (SD, 3.97 cm 3 ). CBCT bladder/ PTV volumes significantly differed from planning CT counterparts (p = 0.047). Conclusions: Significant variations in bladder and PTV volume and position occurred in patients in this trial.

Chemoradiotherapy as a bladder-preservation approach for muscle-invasive bladder cancer. Current status and perspectives

Radical cystectomy has been considered the (gold standard for the treatment of muscle-invasive bladder r cancer. However, because of disappointing results with radical surgery in terms of survival and decreased quality of life (QOL), bladder-preservation treatment has been introduced as an alternative to radical cystectomy. The primary purpose of the bladder-preservation approach has been to maximize overall cure rates, with the secondary purpose being to preserve the patient's bladder. The modalities used to ensure successful bladder preservation include radical transurethral resection (TUR), concurrent cisplatin (CDDP)-based chemotherapy, and radiotherapy. In patients who achieve a complete response (CR) after trimodality therapy, 5-year survival rates of more than 50%, the same as those of radical cystectomy, can be achieved and 70% of this group will retain an intact functional bladder. In this article, bladder-preservation studies using chemoradiotherapy are reviewed. (author)

Work Capacity of the Bladder During Voiding: A Novel Method to Evaluate Bladder Contractile Function and Bladder Outlet Obstruction

Directory of Open Access Journals (Sweden)

Ning Liu

2015-01-01

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.

Bladder calculus is associated with chronic irritation and inflammation. As there is substantial documentation that inflammation can play a direct role in carcinogenesis, to date the relationship between stone formation and bladder cancer (BC) remains unclear. This study aimed to examine the association between BC and prior bladder calculus using a population-based dataset. This case-control study included 2,086 cases who had received their first-time diagnosis of BC between 2001 and 2009 and 10,430 randomly selected controls without BC. Conditional logistic regressions were employed to explore the association between BC and having been previously diagnosed with bladder calculus. Of the sampled subjects, bladder calculus was found in 71 (3.4%) cases and 105 (1.1%) controls. Conditional logistic regression analysis revealed that the odds ratio (OR) of having been diagnosed with bladder calculus before the index date for cases was 3.42 (95% CI = 2.48-4.72) when compared with controls after adjusting for monthly income, geographic region, hypertension, diabetes, coronary heart disease, and renal disease, tobacco use disorder, obesity, alcohol abuse, and schistosomiasis, bladder outlet obstruction, and urinary tract infection. We further analyzed according to sex and found that among males, the OR of having been previously diagnosed with bladder calculus for cases was 3.45 (95% CI = 2.39-4.99) that of controls. Among females, the OR was 3.05 (95% CI = 1.53-6.08) that of controls. These results add to the evidence surrounding the conflicting reports regarding the association between BC and prior bladder calculus and highlight a potential target population for bladder cancer screening.

Abstract Background and Purpose: The effectiveness of locoregional hyperthermia combined with intravesical instillation of mitomycin C to reduce the risk of recurrence and progression of intermediate- and high-risk nonmuscle-invasive bladder cancer is currently investigated in clinical trials. Clinically effective locoregional hyperthermia delivery necessitates adequate thermal dosimetry; thus, optimal thermometry methods are needed to monitor accurately the temperature distribution throughout the bladder wall. The aim of the study was to evaluate the technical feasibility of a novel intravesical device (multi-sensor probe) developed to monitor the local bladder wall temperatures during loco-regional C-HT. Materials and Methods: A multisensor thermocouple probe was designed for deployment in the human bladder, using special sensors to cover the bladder wall in different directions. The deployment of the thermocouples against the bladder wall was evaluated with visual, endoscopic, and CT imaging in bladder phantoms, porcine models, and human bladders obtained from obduction for bladder volumes and different deployment sizes of the probe. Finally, porcine bladders were embedded in a phantom and subjected to locoregional heating to compare probe temperatures with additional thermometry inside and outside the bladder wall. Results: The 7.5 cm thermocouple probe yielded optimal bladder wall contact, adapting to different bladder volumes. Temperature monitoring was shown to be accurate and representative for the actual bladder wall temperature. Conclusions: Use of this novel multisensor probe could yield a more accurate monitoring of the bladder wall temperature during locoregional chemohyperthermia. PMID:24112045

Look Out before Polypectomy in Patients with Diverticular Disease – A Case of a Large, Inverted Diverticulum of the Colon Resembling a Pedunculated Polyp

Full Text Available Diverticular disease of the colon may be responsible for abdominal symptoms requiring colonoscopy, which may reveal the presence of concomitant polyps. A polyp found during colonoscopy in patients with colonic diverticular disease may be removed by endoscopic polypectomy with electrosurgical snare, a procedure associated with an incidence of perforation of less than 0.05%. The risk of such a complication may be higher in the event of an inverted colonic diverticulum, which may be misinterpreted as a polypoid lesion at colonoscopy. To date, fewer than 20 cases of inverted colonic diverticula, diagnosed at colonoscopy or following air contrast barium enema, have been reported in the literature. The present report describes a 68-year-old woman who underwent a screening colonoscopy, which revealed a voluminous pedunculated polyp that was recognized to be an inverted giant colonic diverticulum before endoscopic polypectomy.

Urethral calculi are rare forms of urolithiasis. Majority of the calculi are migratory from urinary bladder or upper urinary tract. Primary urethral calculi usually occur in presence of urethral stricture or diverticulum. In this article we report a case of a giant posterior urethral calculus measuring 7x3x2 cm in a 47 years old male. Patient presented with acute retention of urine which was preceded by burning micturition and dribbling of urine for one week. The calculus was pushed in to the bladder through the cystoscope and was removed by suprapubic cystolithotomy.

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.

Sensory dysfunction of bladder mucosa and bladder oversensitivity in a rat model of metabolic syndrome.

Directory of Open Access Journals (Sweden)

Wei-Chia Lee

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 cancer: overview and disease management. Part 1: non-muscle-invasive bladder cancer.

Science.gov (United States)

Anderson, Beverley

2018-05-10

Part 1 of this two-part article provides an overview of bladder cancer and discusses its management. Since publication of a previous article entitled 'Understanding the role of smoking in the aetiology of bladder cancer' ( Anderson, 2009 ), the author has received many requests for an update. This article provides an overview of bladder cancer and its current management practices, underlining the continued role of smoking as the predominant risk factor in the disease's development. The management of bladder cancer is governed by specific guidelines. Management of non-muscle-invasive cancers, including surgical intervention with transurethral resection, and intravesical therapy using chemotherapy and immunotherapy agents, is discussed. Cystectomy (removal of the bladder), is sometimes necessary. Treatments are effective in reducing tumour recurrence, but the effects of the risks and side-effects on the individual's quality of life can be significant. The prevalence of bladder cancer, and the nature of its management make this cancer one of the most expensive for the NHS to treat. The effectiveness of health promotional strategies in increasing peoples' awareness of their risk of developing the disease, and in enabling them to change long-term health behaviours is discussed. The role of the multidisciplinary team is explored, along with that of the uro-oncology cancer nurse specialist. Part 2 will consider the management of muscle-invasive and metastatic bladder cancer.

Bladder exstrophy (BE) is a complex congenital anomaly characterized by a defect in the closure of the lower abdominal wall and bladder. We aimed to provide an overview of the literature and conduct an epidemiologic study to describe the prevalence, and maternal and case characteristics of BE. We used data from 22 participating member programs of the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR). All cases were reviewed and classified as isolated, syndrome, and multiple congenital anomalies. We estimated the total prevalence of BE and calculated the frequency and odds ratios for various maternal and case characteristics. A total of 546 cases with BE were identified among 26,355,094 births. The total prevalence of BE was 2.07 per 100,000 births (95% CI: 1.90–2.25) and varied between 0.52 and 4.63 among surveillance programs participating in the study. BE was nearly twice as common among male as among female cases. The proportion of isolated cases was 71%. Prevalence appeared to increase with increasing categories of maternal age, particularly among isolated cases. The total prevalence of BE showed some variations by geographical region, which is most likely attributable to differences in registration of cases. The higher total prevalence among male cases and older mothers, especially among isolated cases, warrants further attention. PMID:22002949

OVERACTIVE BLADDER SYNDROME IN CHILDREN

Directory of Open Access Journals (Sweden)

E.L. Vishnevskiy

2007-01-01

Full Text Available Overactive bladder is a specific syndrome characterized by bladder dysfunction that is clinically manifested by imperative urination (pollakiuria, urgency, urgent incontinence and nocturia. This state is very widely spread among children: every fifth child aged 4 to 7 shows typical bladder dysfunction. Quite often if urinary distresses are not studied well enough such children are falsely diagnosed with monosymptom enuresis, which, according to our information, actually happens in only 3,9% of cases. When examining children with urinary disorders it is reasonable to be geared to the protocol of European urologist association. According to this protocol, treatment should be started with antimuscarinimedications. The only antimuscarinic medication for treating children with hyperactive bladder that is legal in Russia is oxybutinin (Driptane, that is presently considered to be the «golden standard» of pharmaceutical treatment of overactive bladder for patients of any age. This statement is based on the modern idea of overactive bladder pathogenesis, that presupposes detrusorhypersensibility to acetylcholine. However, in some cases it might be reasonable to use some other medications, physiotherapy, sometimes as part of complex therapy. If individual dosage is observed, which will enable preventing or significantly lowering possible side effects, oxybutinin will be still considered «the golden standard» for treating overactive bladder for years to come in cases when detrusor hypersensibility to acetylcholine is the key component of bladder dysfunction pathogenesis.Key words: overactive bladder, oxybutinin, urination disorder, children.

Purpose: Hyperthermia combined with Mitomycin C is used for the treatment of non-muscle invasive bladder cancer (NMIBC), using a phased array system of microwave antennas for bladder heating. Often some air is present in the bladder, which effectively blocks the microwave radiation, potentially preventing proper treatment of that part of the bladder. Air can be a relevant fraction of the bladder content and large air pockets are expected to have a noticeable influence on achieved temperatures. Methods: We analysed 14 NMIBC patients treated at our institute with our AMC-4 hyperthermia device with four 70MHz antennas around the pelvis. A CT scan was made after treatment and a physician delineated the bladder on the CT scan. On the same scan, the amount of air present in the bladder was delineated. Using our in-house developed hyperthermia treatment planning system, we simulated the treatment using the clinically applied device settings. We did this once with the air pocket delineated on the CT scan, and once with the same volume filled with bladder tissue. Results: The patients had on average 4.2ml (range 0.8–10.1ml) air in the bladder. The bladder volume was delineated by the physician, that is including air pocket and bladder wall, was on average 253ml (range 93–452ml). The average volume in which changes exceeded 0.25°C was 22ml (range 0–108 ml), with the bladder being up to 2°C cooler when an air pocket was present. Except for extreme cases, there was no evident relation between the quantity of air and the difference in temperature. Conclusion: The effect of an air pocket in the bladder during bladder hyperthermia treatment varies strongly between patients. Generally, this leads to lower temperatures in the bladder, potentially affecting treatment quality, and suggesting that care need be taken to minimise the size of air pockets during hyperthermia treatments.

1986-01-01

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

The preoperative work-up of female urethral diverticula should provide the surgeon with maximum data regarding the anatomy and structure of the diverticulum. Preoperatively, the number of diverticula, as well as the location, size, configuration, and communication to the urethra need to be clearly depicted. The objective of this study was to compare the information gained by voiding cystourethrography (VCUG) and positive-pressure double-balloon urethrography (DBU), and to verify which imaging modality can better delineate the features of the diverticula. Twelve women with a presumptive clinical diagnosis of a urethral diverticulum underwent VCUG followed by DBU, and the radiological data from each modality were compared. In 4 of 12 patients (33.3%) VCUG completely failed in demonstrating the diverticulum, whereas DBU showed a large complex diverticulum in 2 patients and a distinct mid-urethral diverticulum in 2 patients. In the remaining 8 women (66.7%) VCUG delineated only the lower part of the diverticulum, whereas DBU depicted a large diverticulum extending beneath the bladder neck in 3 patients and multiple diverticula in 5 patients. The sensitivity of DBU and VCUG, in our series, was therefore 100 and 66.7%, respectively. The DBU supplied excellent documentation regarding the location, size, configuration, and communication of the diverticula to the urethra in every case, which markedly facilitated surgical excision of the diverticula in 9 of 12 patients. Three patients refused surgery and elected conservative treatment. In our experience, VCUG had a low sensitivity as a screening test for the diagnosis of female urethral diverticula, and failed to demonstrate properly the major structural characteristics of the diverticula, whereas DBU was highly sensitive as a diagnostic tool and supplied excellent anatomical delineation of the diverticula.

We report a case of a patient with right axillary ventricular. Similar congenital anomaly of the right atrium was reported as "right appendage diverticulum or right atrial diverticulum." However, this independent chamber has its own annulus, synchronizes with the right ventricular, and generates large ventricular potential. Under the guidance of the CARTO mapping system (Biosense Webster, Diamond Bar, CA, USA), a right atrioventricular accessory pathway associated with type B Wolff-Parkinson-White syndrome was ablated successfully. This pathway was close to the annulus of the axillary ventricular. The patient remained free of arrhythmia at 1-year follow-up. © 2017 Wiley Periodicals, Inc.

Unlike epithelial tumors, connective tissue tumors are uncommon, representing only 3 % of all bladder tumors. Leiomyoma of the bladder is the most frequent non-epithelial benign tumor of the bladder. Magnetic resonance imaging (MIR) is highly useful for diagnostic purposes and to determine the degree of extension. Only few reports of sonographic findings have been reported for leiomyoma of the bladder. The tumor usually develops within the bladder. Extra-vesicular formations have also been reported as well as a few intramural localizations. The characteristic feature is the absence of mucosal involvement. We analyzed the MRI findings in a case of leiomyoma of the bladder with intra and extra-vesicular development inflammatory reaction of the bladder wall and uterine adherences in a woman with a past history of chronic cystitis. The role of diagnostic MRI is discussed. (author)

Full Text Available The outcome of multimodal therapy for localized bladder rhabdomyosarcoma is quite good in terms of morbidity, and conservative surgery is generally recommended. However, in cases originating in the bladder neck, tumorectomy or partial cystectomy has adverse effects on bladder function. A 2-year-old girl underwent transurethral resection of a bladder tumor (TUR-BT, chemotherapy consisting of vincristine, actinomycin-D, and cyclophosphamide, and radiotherapy. She was in remission for 3 years when frequent urination became evident. Her bladder capacity and compliance were low; however, her urinary symptom was controlled using anticholinergic medication. Accordingly, TUR-BT could be an optional approach for bladder rhabdomyosarcoma. Keywords: Rhabdomyosarcoma, Transurethral resection, Conservative surgery

Several authors have reported an association between neuroblastoma and congenital heart disease; others contend that, unlike specific wellknown associations between malignancy and congenital defects (Wilm's tumor and aniridia, leukemia and Down's syndrome), no real relationship exists. We present three cases of cyanotic congenital heart disease in which subclinical neuroblastoma was found. We speculate that abnormal neural crest cell migration and development may be a common link between cardiac malformations and congenital neuroblastoma. (orig.)

HAMLET is a protein-lipid complex that kills different types of cancer cells. Recently we observed a rapid reduction in human bladder cancer size after intravesical HAMLET treatment. In this study we evaluated the therapeutic effect of HAMLET in the mouse MB49 bladder carcinoma model. Bladder tumors were established by intravesical injection of MB49 cells into poly L-lysine treated bladders of C57BL/6 mice. Treatment groups received repeat intravesical HAMLET instillations and controls received alpha-lactalbumin or phosphate buffer. Effects of HAMLET on tumor size and putative apoptotic effects were analyzed in bladder tissue sections. Whole body imaging was used to study HAMLET distribution in tumor bearing mice compared to healthy bladder tissue. HAMLET caused a dose dependent decrease in MB49 cell viability in vitro. Five intravesical HAMLET instillations significantly decreased tumor size and delayed development in vivo compared to controls. TUNEL staining revealed selective apoptotic effects in tumor areas but not in adjacent healthy bladder tissue. On in vivo imaging Alexa-HAMLET was retained for more than 24 hours in the bladder of tumor bearing mice but not in tumor-free bladders or in tumor bearing mice that received Alexa-alpha-lactalbumin. Results show that HAMLET is active as a tumoricidal agent and suggest that topical HAMLET administration may delay bladder cancer development.

Review of underactive bladder

Directory of Open Access Journals (Sweden)

Full Text Available In clinical practice, many patients cannot empty their bladders within an acceptable duration. Common complaints include weak urinary stream and incomplete emptying, which may affect quality of life. Bladder emptying requires sufficient detrusor contractile power, velocity, and durability. The urodynamic term for inadequate detrusor contraction is detrusor underactivity (DU. Although this definition was provided by the ICS, it may not be clinically practical. Analogous to the relationship between overactive bladder (OAB and detrusor overactivity (DO, the symptom complex caused by DU is termed underactive bladder (UAB. Many conditions lead to UAB, such as advanced age, neurogenic bladder and BOO, but the definite pathophysiology directly leading to UAB is still being widely studied without a widely-accepted consensus. The preferred mainstream treatment for increased residual urine volume caused by UAB is intermittent catheterization, while pharmacotherapy is still disappointing after decades of development. There are no studies on surgical treatment for UAB with an acceptable level of evidence. We reviewed the recent literature on UAB and DU to provide a comprehensive discussion of the related presentation, etiology, diagnosis and management.

Purpose: To assess the spatial variability of a bladder tumor relative to the planning target volume boundaries during radical radiotherapy, and furthermore to develop strategies to reduce spatial variability. Methods and Materials: Seventeen patients with solitary T2-T4N0M0 bladder cancer were treated with a technique delivering 40 Gy/2 Gy in 20 fractions to the whole bladder with a concomitant boost to the bladder tumor of 20 Gy in 1 Gy fractions in an overall time of 4 weeks. CT scans were made weekly, immediately after treatment, and matched with the planning CT scan. Spatial variability of the tumor, as well as bladder volume and rectal diameter, were scored for each patient each week. Results: In 65% of patients, a part of the tumor appeared outside the planning target volume boundaries at least one time during the course of radiotherapy. No consistent relation of this variability with time was found. Bladder volumes and rectal diameters showed marked variability during the course of treatment. A large initial bladder volume and rectal diameter predicted a large volume variation and a large tumor spatial variability. Conclusion: In this study, a margin of 1.5 to 2 cm seemed to be inadequate in 65% of the patients with respect to spatial variability. Bladder volume and rectal diameter were found to be predictive for spatial variability of a bladder tumor during concomitant boost radiotherapy

Duplex gall bladder: bystander or culprit.

Science.gov (United States)

Kumar, Jogender; Yadav, Arushi

2017-08-30

Gall bladder (GB) duplication is a rare anatomical malformation, which can be detected by preoperative imaging study. We present a case of duplex gall bladder in a 14-year-old boy who presented with abdominal pain. On ultrasound, he had right nephrolithiasis and duplex gall bladder. Duplex gall bladder was confirmed on MR cholangiopancreatography. There was a dilemma for surgical management of duplex gall bladder; however, he became asymptomatic after conservative treatment. Prophylactic surgery is not recommended for asymptomatic incidentally detected duplex gall bladder. Radiologists and paediatric surgeons should be sensitised about the exact anatomy of this entity. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Bladder cancer and schistosomiasis

International Nuclear Information System (INIS)

Zaghloul, M.S.

2012-01-01

Schistosoma-associated bladder cancer was believed, for several decades, to be a completely unique entity of disease, different from urothelial cancer. This was probably due to its distinct clinico pathologic and demographic features that varied from those of urothelial entity. The carcinogenesis is an extremely complex process resulting from the accumulation of many genetic and epigenetic changes leading to alterations in the cell proliferation regulation process. In bladder cancer, many of these carcinogenic cascades were not fully documented or somewhat conflicting. In spite of the efforts performed, much is still needed to explore the presence or absence of the carcinogenic difference with a different etiology. The control of schistosomiasis in certain countries and the subsequent decrease in the intensity of infestation showed changing of features approaching that of urothelial tumors. However the schistosoma-associated bladder cancer presented in more advanced stages than schistosoma-non associated urothelial cancer. More recently, data are gathered that, upon applying the same treatment protocol and management care, stage by stage comparison of the treatment end-results were found to be similar in bladder cancer patients with a different etiology. All treatment options; including radical cystectomy with or without adjuvant or neoadjuvant chemo- or radiotherapy or tri modality bladder preserving treatment seem to lead to similar end-results regardless of etiologic factor(s) implicated in bladder cancer development.

Pathobiology and Chemoprevention of Bladder Cancer

Our understanding of the pathogenesis of bladder cancer has improved considerably over the past decade. Translating these novel pathobiological discoveries into therapies, prevention, or strategies to manage patients who are suspected to have or who have been diagnosed with bladder cancer is the ultimate goal. In particular, the chemoprevention of bladder cancer development is important, since urothelial cancer frequently recurs, even if the primary cancer is completely removed. The numerous alterations of both oncogenes and tumor suppressor genes that have been implicated in bladder carcinogenesis represent novel targets for therapy and prevention. In addition, knowledge about these genetic alterations will help provide a better understanding of the biological significance of preneoplastic lesions of bladder cancer. Animal models for investigating bladder cancer development and prevention can also be developed based on these alterations. This paper summarizes the results of recent preclinical and clinical chemoprevention studies and discusses screening for bladder cancer. PMID:21941546

Disulfide high mobility group box-1 causes bladder pain through bladder Toll-like receptor 4.

Bladder pain is a prominent symptom in several urological conditions (e.g. infection, painful bladder syndrome/interstitial cystitis, cancer). Understanding the mechanism of bladder pain is important, particularly when the pain is not accompanied by bladder pathology. Stimulation of protease activated receptor 4 (PAR4) in the urothelium results in bladder pain through release of urothelial high mobility group box-1 (HMGB1). HGMB1 has two functionally active redox states (disulfide and all-thiol) and it is not known which form elicits bladder pain. Therefore, we investigated whether intravesical administration of specific HMGB1 redox forms caused abdominal mechanical hypersensitivity, micturition changes, and bladder inflammation in female C57BL/6 mice 24 hours post-administration. Moreover, we determined which of the specific HMGB1 receptors, Toll-like receptor 4 (TLR4) or receptor for advanced glycation end products (RAGE), mediate HMGB1-induced changes. Disulfide HMGB1 elicited abdominal mechanical hypersensitivity 24 hours after intravesical (5, 10, 20 μg/150 μl) instillation. In contrast, all-thiol HMGB1 did not produce abdominal mechanical hypersensitivity in any of the doses tested (1, 2, 5, 10, 20 μg/150 μl). Both HMGB1 redox forms caused micturition changes only at the highest dose tested (20 μg/150 μl) while eliciting mild bladder edema and reactive changes at all doses. We subsequently tested whether the effects of intravesical disulfide HMGB1 (10 μg/150 μl; a dose that did not produce inflammation) were prevented by systemic (i.p.) or local (intravesical) administration of either a TLR4 antagonist (TAK-242) or a RAGE antagonist (FPS-ZM1). Systemic administration of either TAK-242 (3 mg/kg) or FPS-ZM1 (10 mg/kg) prevented HMGB1 induced abdominal mechanical hypersensitivity while only intravesical TLR4 antagonist pretreatment (1.5 mg/ml; not RAGE) had this effect. The disulfide form of HMGB1 mediates bladder pain directly (not

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 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.

Classic as well as more recent large-scale genomic analyses have uncovered multiple genes and pathways important for bladder cancer development. Genes involved in cell-cycle control, chromatin regulation, and receptor tyrosine and PI3 kinase-mammalian target of rapamycin signaling pathways are commonly mutated in muscle-invasive bladder cancer. Expression-based analyses have identified distinct types of bladder cancer that are similar to subsets of breast cancer, and have prognostic and therapeutic significance. These observations are leading to novel therapeutic approaches in bladder cancer, providing optimism for therapeutic progress. Copyright © 2015 Elsevier Inc. All rights reserved.

Purpose: There is strong interest in partial-bladder radiation whether as a boost or definitive therapy to limit long-term toxicity. It is unclear that a standard preoperative examination can accurately identify all sites of disease within the bladder. The purpose of this study was to determine the correlation between preoperative localization of bladder tumors with postoperative findings to facilitate partial-bladder radiation techniques when appropriate. Methods and Materials: We examined patients with clinically staged T1-T4 invasive transitional cell carcinoma (TCC) or TCC with variant histology with no history of radiation or partial cystectomy undergoing radical cystectomy. Patients were scored as “under-detected” if a bladder site was involved with invasive disease (≥T1) at the time of cystectomy, but not identified preoperatively. Patients were additionally scored as “widely under-detected” if they had postoperative lesions that were not identified preoperatively in a given site, nor in any adjacent site. Rates of under-detected and widely under-detected lesions, as well as univariate and multivariate association between clinical variables and under-detection, were evaluated using logistic regression. Results: Among 222 patients, 96% (213/222) had at least 1 area of discordance. Fifty-eight percent of patients were under-detected in at least 1 location, whereas 12% were widely under-detected. Among 24 patients with a single site of disease on preoperative evaluation, 21/24 (88%) had at least 1 under-detected lesion and 14/24 (58%) were widely under-detected. On multivariate analysis, only solitary site of preoperative disease was associated with increased levels of under-detection of invasive disease (OR = 4.161, 95% CI, 1.368-12.657). Conclusion: Our study shows a stark discordance between preoperative and postoperative localization of bladder tumors. From a clinical perspective, incomplete localization of all sites of disease within the bladder

The aim of this study was to assess the efficacy and safety following endoscopic management of Zenker's diverticulum (ZD) using a needle-knife technique. A systematic search of PubMed, Embase and Cochrane library databases was performed. All original studies reporting efficacy and safety of needle-knife technique for treatment of ZD were included. Pooled event rates across studies were expressed with summative statistics. Main outcomes, such as rates of immediate symptomatic response (ISR), adverse events and recurrence, were extracted, pooled and analyzed. Heterogeneity among studies was assessed using the R statistic. The random effects model was used and results were expressed with forest plots and summative statistics. Thirteen studies included 589 patients were enrolled. Pooled event rates for ISR, overall complication, bleeding and perforation were 88% (95% confidence interval [CI] 79-94%), 13% (95% CI 8-22%), 5% (95% CI 3-10%) and 7% (95% CI 4-12%), respectively. The pooled data demonstrated an overall recurrence rate of 14% (95% CI 9-21%). Diverticulum size of at least 4 cm and less than 4 cm demonstrated pooled adverse event rates of 17% (95% CI 10-27%) and 7% (95% CI 2-18%), respectively. When using diverticuloscope as an accessory, pooled ISR and adverse events rates were 84% (95% CI 58-95%) and 10% (95% CI 3-26%), respectively. Flexible endoscopic procedures using needle-knife offers a relatively safe and effective treatment of symptomatic ZD, especially for ZD of <4 cm in diameter. © 2018 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

2015-05-01

Full Text Available An 11-year-old boy had previously been diagnosed with repeated Meckel's diverticulitis at another hospital. Emergency laparoscopy was performed under general anesthesia, and an inflammatory mass was seen in the ileocecal region of the mesentery. However, no Meckel's diverticulum (MD was observed, and so the patient was diagnosed with lymphadenitis. Three days after the operation, he developed anemia and gastrointestinal bleeding of unknown origin. Thus, he was transferred to our hospital for further investigation and to have his gastrointestinal bleeding treated. Based on imaging scans obtained at the previous hospital, a paraduodenal hernia was suspected, but no paraduodenal hernia was detected during emergency surgery, despite the fact that the full length of the normal small intestine could be traced. However, an inflammatory mass was observed, and the ileum appeared to be incarcerated in a pericecal hernia. We could not identify which portion of the intestine had become entrapped or reduce the hernia due to adhesion. The inflammatory mass was removed by ileocecal resection, and a pathological examination revealed that the entrapped portion of the intestine was an MD that had branched off from the small intestine immediately proximal to the ileocecal valve. The MD had perforated in the hernia sac, which had caused the patient's bleeding.

To introduce a new technique that combines laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in patients with congenital atresia of the cervix. Video article introducing a new surgical technique. University hospital. A 16-year-old patient with congenital cervical atresia, vaginal dysgenesis, and ovarian endometrial cyst. An original technique of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft for cervicovaginal reconstruction. A midline incision at the vaginal introitus was made, and a 9-cm canal was made between the bladder and the rectum using sharp and blunt dissection along the anatomic vaginal route, with the aid of laparoscopy to ensure correct orientation. A 14 × 12 cm split thickness skin graft was harvested from the right lateral thigh. By laparoscopy, the level of the lowest pole of the uterine cavity was exposed and the cervix was incised by shape dissection. The proximal segment of the harvested skin to the lower uterine segment was secured, and the distal segment was sutured with the upper margin of vulva vaginally. Surgical technique reports in anonymous patients are exempted from ethical approval by the Institutional Review Board. The patient gave consent to use the video in the article. The procedure was successfully completed. Since February 2013, our experiences of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in 10 patients with congenital atresia of cervix were positive, with successful results and without complications or cervical, or vaginal stenosis. Our technique is feasible and safe for congenital atresia of cervix, with successful results and without complications or cervical or vaginal stenosis.

A 10-year-old neutered female soft-coated wheaten terrier and a 10-year-old, entire female Pomeranian were presented for vomiting and anorexia. Using ultrasound, an oval structure with a stellate, kiwifruit-like appearance typical of a gall bladder mucocoele was observed in the caudal abdomen of the soft-coated wheaten terrier and adjacent to the liver in the Pomeranian. There was also a moderate volume of abdominal effusion in both dogs. Cytology of the peritoneal fluid indicated a sterile exudative process but varied between the two dogs, with an absence of bile pigment in the soft-coated wheaten terrier and marked bile peritonitis in the Pomeranian. An entire free-floating ectopic mucocoele was confirmed via exploratory laparotomy with concomitant gall bladder rupture and common bile duct obstruction. Both dogs recovered completely after surgery.

Current management of overactive bladder.

Cartwright, Rufus; Renganathan, Arasee; Cardozo, Linda

2008-10-01

The concept of overactive bladder has helped us address the problem of urgency and urge incontinence from a symptomatic perspective. In this review, we provide a critical summary of clinically relevant recent publications, focusing in particular on advances in our understanding of assessment methods and therapeutic interventions for overactive bladder in women. According to current definitions, the prevalence of overactive bladder in western nations is now estimated as 13.0%. Although the prevalence increases with age, the symptoms of overactive bladder may follow a relapsing and remitting course. There has been a proliferation of validated symptom and quality of life measures and increasing sophistication in the analysis of bladder diaries. The role of urodynamics in the evaluation of urgency remains uncertain, with many trials showing limited benefit as a preoperative investigation. Fluid restriction and bladder retraining remain important first-line interventions. Many new anticholinergic medications have been licensed, with limited benefits compared with existing preparations. Intravesical botulinum toxin has become a popular alternative for patients who fail oral therapies. Although there have been few important therapeutic innovations, recent publications have led to greater sophistication in assessment methods and a clearer understanding of the role of existing interventions.

In this straightforward procedure, bladder tumors are established in female C57 mice through the use of catheterization, local cauterization, and subsequent cell adhesion. After their bladders are transurethrally catheterized and drained, animals are again catheterized to permit insertion of a platinum wire into bladders without damaging the urethra or bladder. The catheters are made of Teflon to serve as an insulator for the wire, which will conduct electrical current into the bladder to create a burn injury. An electrocautery unit is used to deliver 2.5W to the exposed end of the wire, burning away extracellular layers and providing attachment sites for carcinoma cells that are delivered in suspension to the bladder through a subsequent catheterization. Cells remain in the bladder for 90 minutes, after which the catheters are removed and the bladders allowed to drain naturally. The development of tumor is monitored via ultrasound. Specific attention is paid to the catheterization technique in the accompanying video.

Estimation of bladder wall location in ultrasound images.

Topper, A K; Jernigan, M E

1991-05-01

A method of automatically estimating the location of the bladder wall in ultrasound images is proposed. Obtaining this estimate is intended to be the first stage in the development of an automatic bladder volume calculation system. The first step in the bladder wall estimation scheme involves globally processing the images using standard image processing techniques to highlight the bladder wall. Separate processing sequences are required to highlight the anterior bladder wall and the posterior bladder wall. The sequence to highlight the anterior bladder wall involves Gaussian smoothing and second differencing followed by zero-crossing detection. Median filtering followed by thresholding and gradient detection is used to highlight as much of the rest of the bladder wall as was visible in the original images. Then a 'bladder wall follower'--a line follower with rules based on the characteristics of ultrasound imaging and the anatomy involved--is applied to the processed images to estimate the bladder wall location by following the portions of the bladder wall which are highlighted and filling in the missing segments. The results achieved using this scheme are presented.

Full Text Available Appendix diverticular disease is a casual finding after appendectomies or pathological studies of surgical samples. Most patients are male adults between the fourth and fifth decade of life. 16 years old male consults for a 48 hours stitch pain in right iliac fossa of moderate intensity radiating to lower abdomen with nausea and fever, without vomiting or diarrhea. Presents lower abdominal pain with muscle guarding and pain on physical examination. Bowel sounds negative. Laboratory routine study shows leukocytosis with neutrophilia. A perforated diverticulum of about 15cm diameter is found during surgery in the middle third of the cecum appendix with 200cc purulent fluid in and multiple adhesions to transverse colon, omentum and small intestine. A conventional appendectomy is performed. Acute appendix diverticulitis is a rare entity and its finding is by casualty. It is important to consider it a differential diagnosis especially in the intraoperative treatment which in most cases does not differ from conventional appendectomy.

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.

Full Text Available Overactive bladder (OAB, as defined by the International Continence Society, is characterized by a symptom complex including urinary urgency with or without urge incontinence, usually associated with frequency and nocturia. OAB syndrome has an incidence reported from six European countries ranging between 12-17%, while in the United States; a study conducted by the National Overactive Bladder Evaluation program found the incidence at 17%. In Asia, the prevalence of OAB is reported at 53.1%. In about 75%, OAB symptoms are due to idiopathic detrusor activity; neurological disease, bladder outflow obstruction (BOO intrinsic bladder pathology and other chronic pelvic floor disorders are implicated in the others. OAB can be diagnosed easily and managed effectively with both non-pharmacological and pharmacological therapies. The first-line treatments are lifestyle interventions, bladder training, pelvic floor muscle exercises and anticholinergic drugs. Antimuscarinics are the drug class of choice for OAB symptoms; with proven efficacy, and adverse event profiles that differ somewhat.

Twenty-three out of 31 patients with clinical T2-4a N0 M0 bladder cancer and given a trial of trimodality therapy including transurethral resection (TUR), systemic chemotherapy and radiation between 1991 and 2002 completed this therapy. The other 8 dropped out because of insufficient clinical effect. Local bladder recurrence was seen in 3 patients and the bladder preservation rate was 64.5%. Nineteen of the 23 patients showed a complete histological response on a subsequent TUR specimen, the other 4 were not examined for histological response. Thirteen of the 19 patients showed a complete histological response after maximal TUR and systemic chemotherapy, while 6 did after TUR, chemotherapy and radiotherapy. Bladder cancer was T2 in, 15, T3 in 1, and T4a in 3 patients. The CR rate for T2 cancer was significantly higher than that for T3-4a cancer. The 5-year disease-specific survival of the 23 patients treated with preservation therapy was 67.1%. Some of the patients with locally advanced bladder cancer may benefit from this preservation therapy. (author)

Purpose: Selective bladder preservation by use of trimodality therapy is an established management strategy for muscle-invasive bladder cancer. Individual disease features have been associated with response to therapy, likelihood of bladder preservation, and disease-free survival. We developed prognostic nomograms to predict the complete response rate, disease-specific survival, and likelihood of remaining free of recurrent bladder cancer or cystectomy. Methods and Materials: From 1986 to 2009, 325 patients were managed with selective bladder preservation at Massachusetts General Hospital (MGH) and had complete data adequate for nomogram development. Treatment consisted of a transurethral resection of bladder tumor followed by split-course chemoradiation. Patients with a complete response at midtreatment cystoscopic assessment completed radiation, whereas those with a lesser response underwent a prompt cystectomy. Prognostic nomograms were constructed predicting complete response (CR), disease-specific survival (DSS), and bladder-intact disease-free survival (BI-DFS). BI-DFS was defined as the absence of local invasive or regional recurrence, distant metastasis, bladder cancer-related death, or radical cystectomy. Results: The final nomograms included information on clinical T stage, presence of hydronephrosis, whether a visibly complete transurethral resection of bladder tumor was performed, age, sex, and tumor grade. The predictive accuracy of these nomograms was assessed. For complete response, the area under the receiving operating characteristic curve was 0.69. The Harrell concordance index was 0.61 for both DSS and BI-DFS. Conclusions: Our nomograms allow individualized estimates of complete response, DSS, and BI-DFS. They may assist patients and clinicians making important treatment decisions.

The prognoses and prognostic factors of the 54 patients with locally invasive bladder cancer who underwent bladder preservation therapy at Yokohama City University Hospital between 1977 and 1995 were analyzed statistically. The therapeutic modalities of bladder preservation were mainly radiation or chemotherapy. The prognosis for the patients who underwent bladder preservation therapy was worse than that for the patients who underwent total cystectomy. The prognostic factors of these patients were size and grade of tumor, presence of hydronephrosis and performance status (PS) of the patients by univariate analysis. Tumor grade was the most predictable prognostic factor using multivariate analysis. Only 17 patients survived more than 5 years after treatment; 78% of the survivors had good PS (0 or 1). Five of them died of cancer and two patients were alive with cancer. All of them had G3 tumors. These results suggest that patients with locally invasive G2 tumor could be candiates for bladder preservation therapy and patients who underwent bladder preservation therapy should be evaluated at 10 years post-therapy.

Full Text Available Construction of the urinary bladder de novo using tissue engineering technologies is the “holy grail” of reconstructive urology. The search for the ideal biomaterial for urinary bladder reconstruction has been ongoing for decades. One of the most promising biomaterials for this purpose seems to be bladder acellular matrix (BAM. In this review we determine the most important factors, which may affect biological and physical properties of BAM and its regeneration potential in tissue engineered urinary bladder. We also point out the directions in modification of BAM, which include incorporation of exogenous growth factors into the BAM structure. Finally, we discuss the results of the urinary bladder regeneration with cell seeded BAM.

Background and Purpose: For cervical cancer patients, bladder filling variations may result in inadequate EBRT target coverage, unless large safety margins are used. For a group of patients who received full bladder instructions, inter-fraction variations and time trends in bladder volume were quantified, and a 3D ultrasound (US) scanner was tested for on-line bladder volume measurements. Methods and materials: For 24 patients, the bladder volume was measured with US at the time of the planning CT scan, and twice weekly during the course of RT. Comparisons of US with planning CT were used to assess the bladder scanner accuracy. Patients were treated in prone on a belly board, EPID images were acquired to correlate set-up errors with bladder filling variations. Results: Measured US and CT bladder volumes were strongly correlated (R = 0.97, slope 1.1 ± 0.1). The population mean bladder volume at planning of 378 ± 209 ml (1 SD) reduced to 109 ± 88 ml (1 SD) in week 6, a reduction by 71% (average reduction 46 ml/week), revealing a large inter-fraction time trend. Intra-patient variation in bladder volume during RT was 168 ml (1 SD) (range 70-266 ml). Rotation around the LR axis was significantly correlated with bladder volume changes. Conclusions: Despite a full bladder instruction, bladder volumes reduced dramatically during treatment, implying large time trends in target position of these patients. The portable US scanner provides a quick and reliable measurement of the bladder volume, which might assist future online treatment adaptation

Purpose: Chronic radiation cystitis is an uncommon but debilitating late complication of definitive external beam (EB) and brachytherapy (BT) for cervix cancer. During BT an indwelling catheter is usually placed in the bladder, collapsing it closer to the BT sources. We have devised a method to deliver BT with a full bladder. The difference in bladder dose in the full and empty state were analyzed during definitive EBT and BT for cervix cancer. Methods: The technique of Lyman and Wolbarst (1) were used to evaluate the bladder complication probability for a representative cervix cancer patient undergoing EBT and BT. DVHs were generated from CT scans obtained with a full and empty bladder. Three possible dose prescriptions were analyzed. Results: The DVH for the full and empty situations are shown. With the bladder full, the volume of bladder predicted to receive ≥ 80 Gy was approximately 10% for all dose schemes evaluated, whereas with the bladder empty, up to 50% of the bladder volume received ≥ 80 Gy. Conclusions: A distended bladder improves the DVH. A technique for performing full bladder LDR brachytherapy will be discussed

Bladder cancer is currently the fifth most common cancer in Western society, and its incidence appears to be increasing. Important advances have recently occurred in both diagnostic and therapeutic approaches to bladder neoplasms. Presentation is not unique, and physician awareness is important to identify patients who are at risk for bladder neoplasia and consequently require further investigation. A diagnostic approach and contemporary management are discussed. ImagesFigure 1Figure 4 PMID:21229043

The ability to repair damaged urinary bladders through the application of bone marrow-derived cells is in the earliest stages of development. We investigated the application of bone marrow-derived cells to repair radiation-injured bladders. We used a three-dimensional (3D) bioprinting robot system to biofabricate bone marrow-derived cell structures. We then determined if the biofabricated structures could restore the tissues and functions of radiation-injured bladders. The bladders of female 10-week-old Sprague-Dawley (SD) rats were irradiated with 2-Gy once a week for 5 weeks. Adherent and proliferating bone marrow-derived cells harvested from the femurs of male 17-week-old green fluorescence protein-transfected Tg-SD rats were cultured in collagen-coated flasks. Bone marrow-derived cell spheroids were formed in 96-well plates. Three layers of spheroids were assembled by the bioprinter onto a 9x9 microneedle array. The assembled spheroids were perfusion cultured for 7 days, and then the microneedle array was removed. Two weeks after the last radiation treatment, the biofabricated structures were transplanted into an incision on the anterior wall of the bladders (n=10). Control rats received the same surgery but without the biofabricated structures (sham-structure, n=12). At 2 and 4 weeks after surgery, the sham-structure control bladder tissues exhibited disorganized smooth muscle layers, decreased nerve cells, and significant fibrosis with increased presence of fibrosis-marker P4HB-positive cells and hypoxia-marker HIF1α-positive cells. The transplanted structures survived within the recipient tissues, and blood vessels extended within them from the recipient tissues. The bone marrow-derived cells in the structures differentiated into smooth muscle cells and formed smooth muscle clusters. The recipient tissues near the transplanted structures had distinct smooth muscle layers and reconstructed nerve cells, and only minimal fibrosis with decreased presence of P4

Full Text Available Although real-time monitoring of bladder volume together with intravesical pressure can provide more information for understanding the functional changes of the urinary bladder, it still entails difficulties in the accurate prediction of real-time bladder volume in urodynamic studies with small animal models. We studied a new implantable bladder volume monitoring device with eight rats. During cystometry, microelectrodes prepared by the microelectromechanical systems process were placed symmetrically on both lateral walls of the bladder, and the expanded bladder volume was calculated. Immunohistological study was done after 1 week and after 4 weeks to evaluate the biocompatibility of the microelectrode. From the point that infused saline volume into the bladder was higher than 0.6 mL, estimated bladder volume was statistically correlated with the volume of saline injected (p<0.01. Additionally, the microelectromechanical system microelectrodes used in this study showed reliable biocompatibility. Therefore, the device can be used to evaluate changes in bladder volume in studies with small animals, and it may help to provide more information about functional changes in the bladder in laboratory studies. Furthermore, owing to its biocompatibility, the device could be chronically implanted in conscious ambulating animals, thus allowing a novel longitudinal study to be performed for a specific purpose.

We investigated the effects of silodosin, an α1A-adrenoceptor (AR) antagonist, on bladder function, especially on non-voiding contractions (NVCs), in a male rat model of bladder outlet obstruction (BOO) by evaluating cystometry (CMG) findings and bladder mechanosensitive single-unit afferent activities (SAAs), related with microcontractions, which may be similar with NVCs and to be of myogenic origin, in the rat model. BOO was created by partial ligation of the posterior urethra. At 4 days after surgery for BOO, an osmotic pump filled with silodosin (0.12 mg/kg/day) or its vehicle was subcutaneously implanted. At 10 days after surgery, CMG and SAAs measurements were taken under conscious and urethane-anesthetized conditions, respectively. The SAAs of Aδ- and C-fibers, which were identified by electrical stimulation of the pelvic nerve and by bladder distention, and intravesical pressure were recorded during constant bladder-filling with saline. Microcontractions were divided into three phases: "ascending," "descending," and "stationary." The silodosin-treated group showed a smaller number of NVCs in CMG measurements and lower SAAs of both Aδ- and C-fibers than the vehicle-treated group during bladder-filling. Moreover, in the vehicle-treated groups, the SAAs of both fibers for the ascending phase of microcontractions were significantly higher than those for the other two phases. On the contrary, no significant change was found between any of these three phases in the silodosin-treated group. The present results suggest that silodosin inhibits the SAAs of mechanosensitive Aδ- and C-fibers at least partly due to suppressing myogenic bladder contractions in male BOO rats. © 2018 Wiley Periodicals, Inc.

Full Text Available Background: The aim of this study was to investigate bladder wall thickness (BWT and ultrasound estimated bladder weight (UEBW values in healthy population with a portative ultrasound device and their relationship with demographic parameters. Materials and Methods: The study was carried out in Neurorehabilitation Clinic of Ege University Hospital. Ninety-five subjects (48 women and 47 men aged between 18 and 56 were included in the study. 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.

Hayashi, Norio; Arima, Kiminobu; Kawamura, Juichi; Tochigi, Hiromi

1999-01-01

The possibility of bladder preservation by preoperative balloon occluded arterial infusion (BOAI) chemotherapy was studied in 111 patients with locally invasive bladder cancer. BOAI was performed by blocking the blood flow of the internal iliac artery and by performing intra-arterial infusion of adriamycin (50 mg/body) and cisplatin (100 mg/body). Before BOAI the clinical diagnosis was T2 in 36, T3a in 29, T3b in 27, T4 in 11 and after BOAI it was T0 in 1, T1 in 27, T2 in 25, T3a in 20, T3b in 20, and T4 in 10. Down staging was observed on diagnostic images in 46.6%. Thirty patients (27.0%) received transurethral resection of bladder tumor (TUR-Bt) and their bladder could be preserved. The 5-year cancer-specific survival rate was 100% in pT0 (n=9), 97.5% in pT1 (n=47), 79.9% in pT2 (n=21), 80.0% in pT3a (n=6), 39.9% in pT3b (n=18) and 51.9% in pT4 cases (n=9). For the bladder preservation, accurate staging diagnosis is required. Since 1992, endorectal magnetic resonance imaging (MRI) has been used in addition to imaging diagnosis for improving the accuracy of staging diagnosis. The accuracies of staging diagnosis with and without endorectal MRI were 62.5% and 44.0%, respectively. BOAI as a neoadjuvant chemotherapy has the possibility of bladder-preserving therapy in locally invasive bladder cancer. Also, the endorectal MRI can improve the accuracy of staging diagnosis, which is important for the bladder preservation. (author)

Conventional sacral anterior root stimulation (SARS) results in simultaneous activation of both the detrusor muscle and the external urethral sphincter. We evaluated the possibilities of different neurostimulation techniques to overcome stimulation induced detrusor-sphincter-dyssynergia and to achieve a physiological voiding. The literature was reviewed on different techniques of sacral anterior root stimulation of the bladder and the significance of posterior rhizotomy in patients with supraconal spinal cord injury suffering from the loss of voluntary bladder control, detrusor hyperreflexia and sphincter spasm. The achievement of selective detrusor activation would improve current sacral neurostimulation of the bladder, including the principle of "poststimulus voiding". This is possible with the application of selective neurostimulation in techniques of anodal block, high frequency block, depolarizing prepulses and cold block. Nowadays, sacral deafferentation is a standard therapy in combination with neurostimulation of the bladder because in conclusion advantages of complete rhizotomy predominate. The combination of sacral anterior root stimulation and sacral deafferentation is a successful procedure for restoration of bladder function in patients with supraconal spinal cord injury. Anodal block technique and cryotechnique are excellent methods for selective bladder activation to avoid detrusor-sphincter-dyssynergia and thus improve stimulation induced voiding.

Conformal radiotherapy for rectal cancer is associated with small bowel toxicity mainly diarrhea. Treating patients with a full bladder is one of the practical solutions to reduce small bowel toxicity. Previous studies on prostate and cervix cancer patients revealed that maintaining consistent bladder volume throughout radiotherapy treatment is challenging. The aim of this study was to measure bladder volume variation throughout radiotherapy treatment. This study also measured the association between bladder volume changes and diarrhea. Twenty two rectal cancer patients were recruited prospectively. Patients were planned for treatment with full bladder following departmental bladder filling protocol and the planning bladder volume was measured during CT-simulation. During radiotherapy, the bladder volume was measured weekly using cone-beam computed tomography (CBCT) and compared to planning bladder volume. Incidence and severity of diarrhea were recorded during the weekly patient review. There was a negative time trend for bladder volume throughout five weeks treatment. The mean bladder volume decreased 18 % from 123 mL (SD 54 mL) during CT-simulation to 101 mL (SD 71 mL) on the 5th week of radiotherapy, but the decrease is not statistically significant. However, there was a large variation of bladder volume within each patient during treatment. This study showed an association between changes of bladder volume and diarrhea (P = 0.045). In conclusion bladder volume reduced throughout radiotherapy treatment for conformal radiotherapy for rectal cancer and there was a large variation of bladder volume within patients.

R F Sholan

2018-02-01

Full Text Available Interstitial cystitis, or painful bladder syndrome, is a chronic inflammatory disease of a bladder of unknown etiology. It negatively affects the quality of life, causes depressive disorders, anxiety, and sexual dysfunction. Despite numerous studies, the etiology of interstitial cystitis is still unclear and it’s considered as painful bladder syndrome with multifactorial origin. According to the US National Health and Nutrition Examination Survey, 470/100 000 people (60/100 000 men, 850/100 000 women are diagnosed with interstitial cystitis. Diagnosis of the disease is difficult and is substantially based on clinical symptoms. Pelvic pain, urinary urgency, frequency and nocturia are the basic complaints in this pathology. The diagnosis requires exclusion of diseases with similar manifestations. So interstitial cystitis is frequently misdiagnosed as urinary tract infection, overactive bladder, urethral obstruction or diverticulosis, chronic prostatitis, bladder cancer, vulvodynia, endometriosis, and chronic pelvic pain. Etiopathogenesis of the disease is uncertain, which makes etiologic treatment impossible. Currently scientific discussions on the causes of disease continue as well as different treatment regimens are offered, but are often ineffective, palliative and temporary. The treatment for intersticial cystitis should focus on restoring normal bladder function, prevention of relapse of symptoms and improvement of patients’ quality of life. The literature review presents current view on the terminology, epidemiology, diagnosis and treatment of interstitial cystitis.

Bladder Dysfunction and Vesicoureteral Reflux

Full Text Available In this overview the influence of functional bladder disturbances and of its treatment on the resolution of vesicoureteral reflux (VUR in children is discussed. Historically both bladder dysfunction entities, the overactive bladder (OAB and the dysfunctional voiding (DV, have been described in conjunction with VUR. Treatment of the dysfunction was also considered to influence spontaneous resolution in a positive way. During the last decades, however, papers have been published which could not support these results. Regarding the OAB, a prospective study with treatment of the bladder overactivity with anticholinergics, did not influence spontaneous resolution rate in children with a dysfunction including also the voiding phase, DV and DES (dysfunctional elimination syndrome, most studies indicate a negative influence on the resolution rate of VUR in children, both before and after the age for bladder control, both with and without treatment. However, a couple of uncontrolled studies indicate that there is a high short-term resolution rate after treatment with flow biofeedback. It should be emphasized that the voiding phase dysfunctions (DV and DES are more severe than the genuine filling phase dysfunction (OAB, with an increased frequency of UTI and renal damage in the former groups. To be able to answer the question if treatment of bladder dysfunction influence the resolution rate of VUR in children, randomized controlled studies must be performed.

Zapping Zenker’s Diverticulum: Gastroscopic Treatment

Full Text Available Zenker’s diverticulum (ZD is a common cause of dysphagia in the elderly. Many symptomatic elderly are poor candidates for surgery and/or ear, nose and throat treatment. The author’s first experiences with gastroscopic treatment by cutting the Zenker bridge to allow an overflow have recently been published. Only patients with contraindications for general anesthesia were accepted to the pilot group. However, the author now treats all ZD patients in this manner. One hundred and twenty-five patients (male to female ratio 1.6 were referred for treatment from 1993 to 1997. After introduction of the gastroscope into the esophagus, a nasogastric tube was positioned to treat a ZD bridge with a height of less than 1 cm. The ZD bridge was divided by argon plasma coagulation, if necessary, in combination with monopolar forceps, Savary dilator and/or precut needle. All patients received antibiotics, topical anesthesia to the throat, if necessary, and intravenous midazolam, if possible. Radiography was performed after treatment. Normalization of the diet was allowed when the x-ray showed no signs of leakage. All patients referred for treatment were treated successfully. The median age was 77 years (range 41 to 100 years. Symptomatic improvement was seen in all patients after treatment. Complications included subcutaneous emphysema (n=17, mediastinal emphysema (n=5 and bleeding (n=2. One patient (95 years of age died in her nursing home 27 days after treatment due to massive pulmonary embolism. The thirty-day mortality rate was otherwise zero. Three patients had been previously treated by surgeons and 12 by ear, nose and throat physicians, without sufficient improvement; all were adequately treated by the author. The mean number of treatment sessions was 1.8. This approach seems safe and effective. Treatment of every patient was possible and was carried out, even in patients in very poor condition, without general anesthesia.

Around 10 % of colorectal cancers are locally advanced at diagnosis. There are higher incidences for sigmoid and rectal cancer adhered to urinary bladder (UB) rather than other segments of colon cancer. Surgeons often performed partial cystectomy as possible for preservation of patient's life quality. This study investigates prognostic factors in patients who underwent bladder preservation en bloc resection for UB adherent colorectal cancer. From 2000 to 2011, 123 patients with clinically UB involvement colorectal cancer underwent primary colorectal cancer with urinary bladder resection. Seventeen patients were excluded because of the concurrent distant metastasis at diagnosis and another 22 patients were excluded because of total cystectomy with uretero-ileal urinary diversion. Finally, 84 patients with clinical stage IIIC (T4bN0M0, according to AJCC 7th edition) that underwent en bloc colorectal cancer resection with partial cystectomy were enrolled into this study for further analysis. Preoperative colovesical fistula and positive CT result were significantly more in the urinary bladder invasion group (p = 0.043 and 0.010, respectively). Pathological UB invasion is an independent predictor of intravesical recurrence (p = 0.04; HR, 10.71; 95 % CI = 1.12∼102.94) and distant metastasis (p = 0.016; HR, 4.85; 95 % CI = 1.34 ∼ 17.53) in multivariate analysis. For bladder preservation en bloc resection of urinary bladder adherent colorectal cancer, the pathological urinary bladder invasion is significantly associated with more urinary bladder recurrence and distant metastasis. This result helps surgeons make decisions at surgical planning and establish follow-up protocol.

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. © RSNA, 2012.

Postpartum bladder rupture is an uncommon surgical emergency and a diagnostic challenge. A primigravida delivered a healthy newborn without complications at 39.4 weeks of gestation. The patient was admitted 80 hours postpartum with abdominal pain, oliguria, hematuria, and pain that worsened during the previous 4 hours. An inserted Foley catheter drained only a small amount of urine, and serum creatinine was elevated (3.5 mg/dL). A laparotomy was performed and revealed a 10-cm hole in the urinary bladder. The bladder was repaired and the patient was discharged 15 days after surgery. The follow-up cystoscopy revealed adequate healing of the bladder. Urinary retention can lead to serious complications, including bladder rupture. Postpartum bladder rupture due to urinary retention should be ruled out if there is a history of abdominal pain, oliguria, and elevated of serum creatinine.

Applications of Nanotechnology in Bladder Cancer Therapy

Full Text Available Effective therapies can prevent superficial bladder cancer from developing into muscle-invasive stage or more severe stages which require radical cystectomy and negatively affect life quality. In terms of therapeutic approaches against superficial bladder cancer, intravesical (regional therapy has several advantages over oral (systemic therapy. Though urologists can directly deliver drugs to bladder lesions by intravesical instillation after transurethral resection, the efficacy of conventional drug delivery is usually low due to the bladder permeability barrier and bladder periodical discharge. Nanoparticles have been well developed as pharmaceutical carriers. By their versatile properties, nanoparticles can greatly improve the interactions between urothelium and drugs and also enhance the penetration of drugs into urothelium with lesions, which dramatically improves therapeutic efficacy. In this review, we discuss the advances of nanotechnology in bladder cancer therapy by different types of nanoparticles with different encapsulating materials.

Surgical treatment of anatomic bladder outlet obstruction (BOO) may be indicated in males with neurogenic bladder dysfunction. A bothersome complication after surgery is urinary incontinence. To identify the optimal practice in the surgical treatment of anatomic BOO in males with neurogenic bladder dysfunction, due to multiple sclerosis, Parkinson disease, spinal cord injury (SCI), spina bifida, or cerebrovascular accident (CVA). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Medline, Embase, Cochrane controlled trial databases, Web of Science, and Google Scholar were searched for publications until January 2017. A total of 930 abstracts were screened. Eight studies were included. The types of anatomic BOO discussed were benign prostate obstruction, urethral stricture, and bladder neck sclerosis. The identified surgical treatments were transurethral resection of the prostate (TURP) in patients with Parkinson, CVA or SCI, endoscopic treatment of urethral stricture by laser ablation or urethrotomy (mainly in SCI patients), and bladder neck resection (BNR) in SCI patients. The outcome of TURP may be highly variable, and includes persistent or de novo urinary incontinence, regained normal micturition control, and urinary continence. Good results were seen in BNR and endoscopic urethrotomy studies. Laser ablation and cold knife urethrotomy resulted in restarting intermittent catheterization or adequate voiding. Overall, a high risk of bias was found. This systematic review provides an overview of the current literature on the outcome of several surgical approaches of different types of anatomic BOO in males with neurogenic bladder dysfunction. Identifying the optimal practice was impossible due to limited availability of high-quality studies.

Radio-chemo-therapy with 5FU and cisplatin for bladder cancer after TUR-bladder

International Nuclear Information System (INIS)

Schuchardt, U.; Birkenhake, S.; Leykam, S.; Martus, P.; Sauer, R.

1996-01-01

Purpose/Objective: To determine toxicity and efficacy of radio-chemo-therapy (RCT) with 5FU and cisplatin in patients with bladder cancer. Endpoints are initial response, cystectomy-rates and overall-survival. Materials and Methods: From 11/93 to 1/95 13 patients suffering from bladder cancer were first treated with TUR-bladder (TURB). Patient characteristics were as follows: Within 6 weeks after operation the pelvis was irradiated with 54.0 Gy (median) in conventional fractionation (10 MV photons 4-field-box). The bladder was boosted up to 59.4 Gy (median) in isocentric rotation technique. 7 patients were treated with 45 Gy paraaortal. During the first and 5th treatment week chemotherapy (CT) was simultaneously given: 800 mg/m 2* d CISPLATIN as bolus-infusion 30 min prior to RT. 2 months later a further TURB was performed for restaging. Cystectomy was recommended, if invasive cancer was found at this time. Acute hematological and gastrointestinal toxicity was recorded according to the WHO-criteria. Results: At least 81% (e.g. 75% of 2nd course) of CT was applied in 10/13 patients. Median doses were 3500 mg/m 2 5FU and 200 mg/m 2 CISPLATIN. Acute toxicity to bladder and bowel reached grade 2 WHO only. Hematotoxicity (median values) and results ar shown in the following table. Conclusion: Concomitant RCT with 5FU and CISPLATIN seems to be a promising modality for organ-preserving therapy of bladder cancer. Preliminary results show sufficient effect and acceptable toxicity. Since patient number is still low, further investigation is recommended

Purpose/Objective: To assess the success of selective organ preservation or radical cystectomy in a large group of patients with muscle-invasive bladder cancer treated with induction by combined transurethral resection (TURBT), systemic chemotherapy and radiation therapy. Materials and Methods: 106 patients (median age 68 years) were treated with induction by maximal TURBT and 2 cycles of chemotherapy (methotrexate, cisplatin, vinblastine - MCV) followed by 39.6 Gy irradiation in 1.8 Gy fractions with concomitant cisplatin. Tumor response was then evaluated by cystoscopy, rebiopsy, and urine cytology. Complete responders were consolidated with radiation to 64.8 Gy and further cisplatin. Any subsequent isolated invasive local relapse was managed by cystectomy. Patients with any less than a complete response (CR) were recommended cystectomy. Median follow-up was 4.4 years. Kaplan-Meier analysis was used to assess outcome. Results: 74 CR patients (70%) and 7 non-cystectomy candidates with less than a CR (7%) received consolidation chemotherapy and radiation. 13 incomplete responders (12%) underwent immediate cystectomy. 6 patients underwent cystectomy because they could not tolerate induction chemo-radiation. 1 complete response patient underwent radical cystectomy. 83 patients completed their planned therapy but 5 died of treatment related toxicity during induction chemotherapy. Five year actuarial overall survival and disease-specific survival were 52% and 60% respectively. For T2 patients, actuarial overall survival was 63%, and for T3-4, 45%. Five year survival with an intact functioning bladder was 43%. Five year freedom from distant metastases was 66%. Of those who had a CR after TURBT and MCV, the risk of a subsequent invasive bladder relapse was 18% at 5 years. Of those who had a CR after the completion of induction chemotherapy and 39.6 Gy, this risk was 21%. 18 patients (17%) have experienced a non-invasive bladder relapse requiring further TUR and

Purpose: The aim of this study is to develop and validate a generic method for automatic bladder segmentation on cone beam computed tomography (CBCT), independent of gender and treatment position (prone or supine), using only pretreatment imaging data. Methods: Data of 20 patients, treated for tumors in the pelvic region with the entire bladder visible on CT and CBCT, were divided into four equally sized groups based on gender and treatment position. The full and empty bladder contour, that can be acquired with pretreatment CT imaging, were used to generate a patient-specific bladder shape model. This model was used to guide the segmentation process on CBCT. To obtain the bladder segmentation, the reference bladder contour was deformed iteratively by maximizing the cross-correlation between directional grey value gradients over the reference and CBCT bladder edge. To overcome incorrect segmentations caused by CBCT image artifacts, automatic adaptations were implemented. Moreover, locally incorrect segmentations could be adapted manually. After each adapted segmentation, the bladder shape model was expanded and new shape patterns were calculated for following segmentations. All available CBCTs were used to validate the segmentation algorithm. The bladder segmentations were validated by comparison with the manual delineations and the segmentation performance was quantified using the Dice similarity coefficient (DSC), surface distance error (SDE) and SD of contour-to-contour distances. Also, bladder volumes obtained by manual delineations and segmentations were compared using a Bland-Altman error analysis. Results: The mean DSC, mean SDE, and mean SD of contour-to-contour distances between segmentations and manual delineations were 0.87, 0.27 cm and 0.22 cm (female, prone), 0.85, 0.28 cm and 0.22 cm (female, supine), 0.89, 0.21 cm and 0.17 cm (male, supine) and 0.88, 0.23 cm and 0.17 cm (male, prone), respectively. Manual local adaptations improved the segmentation

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

To describe the early experience of analyzing variations and time trends in bladder volume of the rectal cancer patients who received bladder ultrasound scan. We identified 20 consecutive rectal cancer patients who received whole pelvic radiotherapy (RT) and bladder ultrasound scan between February and April 2012. Before simulation and during the entire course of treatment, patients were scanned with portable automated ultrasonic bladder scanner, 5 times consecutively, and the median value was reported. Then a radiation oncologist contoured the bladder inner wall shown on simulation computed tomography (CT) and calculated its volume. Before simulation, the median bladder volume measured using simulation CT and bladder ultrasound scan was 427 mL (range, 74 to 1,172 mL) and 417 mL (range, 147 to 1,245 mL), respectively. There was strong linear correlation (R = 0.93, p < 0.001) between the two results. During the course of treatment, there were wide variations in the bladder volume and every time, measurements were below the baseline with statistical significance (12/16). At 6 weeks after RT, the median volume was reduced by 59.3% to 175 mL. Compared to the baseline, bladder volume was reduced by 38% or 161 mL on average every week for 6 weeks. To our knowledge, this study is the first to prove that there are bladder volume variations and a reduction in bladder volume in rectal cancer patients. Moreover, our results will serve as the basis for implementation of bladder training to patients receiving RT with full bladder.

Laparoscopic hernia repair and bladder injury.

Bladder injury is a complication of laparoscopic surgery with a reported incidence in the general surgery literature of 0.5% and in the gynecology literature of 2%. We describe how to recognize and treat the injury and how to avoid the problem. We report two cases of bladder injury repaired with a General Surgical Interventions (GSI) trocar and a balloon device used for laparoscopic extraperitoneal inguinal hernia repair. One patient had a prior appendectomy; the other had a prior midline incision from a suprapubic prostatectomy. We repaired the bladder injury, and the patients made a good recovery. When using the obturator and balloon device, it is important to stay anterior to the preperitoneal space and bladder. Prior lower abdominal surgery can be considered a relative contraindication to extraperitoneal laparoscopic hernia repair. Signs of gas in the Foley bag or hematuria should alert the surgeon to a bladder injury. A one- or two-layer repair of the bladder injury can be performed either laparoscopically or openly and is recommended for a visible injury. Mesh repair of the hernia can be completed provided no evidence exists of urinary tract infection. A Foley catheter is placed until healing occurs.

Full Text Available The results of following up infants with intrauterine infections and malformations were retrospectively analyzed. Infants with malformations were diagnosed as having congenital cytomegalovirus infection and congenital toxoplasmosis in 127 and 69 cases, respectively. The aim of the study was to characterize malformations in infants with congenital cytomegalovirus and congenital Toxoplasma infections. The infants with malformations in congenital cytomegalovirus infection were found to have higher mortality rates (61,4% than those with congenital toxoplasmosis (34,8%. Postmortem analysis indicated that there was a predominance of embryopathies in infants with congenital cytomegalovirus infection and that of fetopathies in those with congenital toxoplasmosis. The dead infants with congenital cytomegalovirus infection had more commonly developed visceral defects, including heart diseases, pneumopathies, gastrointestinal and genitourinary abnormalities; fetopathies of the central nervous system and eye were prevalent in congenital toxoplasmosis. The surviving children with congenital toxoplasmosis were more frequently observed to have disabling CNS and ocular sequels as obstructive hydrocephalus, infantile cerebral palsy, complete or partial blindness, and cerebrasthenic disorders than those with congenital cytomegalovirus infection.

Full Text Available Tanweer Karim, Margaret Topno, Vinod Sharma, Raymond Picardo, Ankur HastirSurgery, MGM Medical College, Kamothe, Navi Mumbai, IndiaAbstract: Bladder injuries are very common in patients who have had road traffic accidents. The method of diagnosis and management of such injuries is well established and accepted. However, trauma to the bladder can be associated with other life-threatening injuries which are frequently missed, and often diagnosed during laparotomy for other reasons. The aim of this study was to diagnose bladder injury in polytrauma patients as early as possible, taking into consideration the fact that these patients are hemodynamically unstable and require rapid evaluation and management. In order to achieve our objective, we used bedside sonography with retrograde instillation of normal saline to diagnose bladder injury in addition to use of the conventional retrograde cystogram.Keywords: bladder injury, bladder rupture, retrograde cystogram

Overactive bladder – 18 years – Part II

Directory of Open Access Journals (Sweden)

Jose Carlos Truzzi

2016-04-01

Full Text Available ABSTRACT Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning – as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder – 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

The purpose of this study was to evaluate the efficacy and safety of onabotulinumtoxinA injections at bladder base/trigone and compare with injections at bladder body or bladder body/trigone for the treatment of idiopathic detrusor overactivity (IDO) refractory to antimuscarinics. A single blind, randomized, paralleled, actively controlled trial was performed in patients with urodynamically proven IDO who failed antimuscarinic therapy. Patients were randomly assigned to receive intravesical injections of 100 U of onabotulinumtoxinA into three different bladder sites. All treatments were evaluated by voiding diary variables, urgency severity score, urodynamic studies, and patient perception of bladder condition. Long-term success rates over 12 months were also determined. Among the patients, 37 were randomized to injections in the bladder body, 35 into the bladder body/trigone, and 33 into the bladder base/trigone. Successful results were reported in 76 (72%) patients at 3 months: 26 (70%) in the bladder body group, 26 (74%) in the bladder body/trigone group, and 24 (73%) in the bladder base/trigone group. There were no significant differences in success rates, changes in urgency and urgency incontinence episodes, urodynamic variables, or long-term success rates among the three subgroups. The incidence of adverse events was similar among three groups. No vesicoureteral reflux was noted in all patients with or without involving trigone injection. Intravesical onabotulinumtoxinA injection is an effective treatment for IDO regardless of the bladder injection site. Bladder base/trigone injection is as safe and effective as bladder body injections with or without trigone involvement. Copyright © 2011 Wiley-Liss, Inc.

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

Gall bladder function test with Ceruletid

International Nuclear Information System (INIS)

Schindler, G.

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 μg/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 conrements 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.

Arsenic and urinary bladder cell proliferation

Luster, Michael I.; Simeonova, Petia P.

2004-01-01

Epidemiologic studies have demonstrated that a close association exists between the elevated levels of arsenic in drinking water and the incidence of certain cancers, including transitional cell carcinomas of the urinary bladder. We have employed in vitro and in vivo models to examine the effects of sodium arsenite on the urinary bladder epithelium. Mice exposed to 0.01% sodium arsenite in drinking water demonstrated hyperproliferation of the bladder uroepithelium within 4 weeks after initiating treatment. This occurred in the absence of amorphous precipitates and was accompanied by the accumulation of trivalent arsenite (iAs 3+ ), and to a lesser extent dimethylarsenic (DMA), arsenate (iAs 5+ ), and monomethylarsenic (MMA) in bladder tissue. In contrast to the bladder, urinary secretion was primarily in the form of DMA and MMA. Arsenic-induced cell proliferation in the bladder epithelium was correlated with activation of the MAP kinase pathway, leading to extracellular signal-regulated kinase (ERK) kinase activity, AP-1 activation, and expression of AP-1-associated genes involved in cell proliferation. Activation of the MAP kinase pathway involved both epidermal growth factor (EGF) receptor-dependent and -independent events, the latter involving Src activation. Studies summarized in this review suggest that arsenic accumulates in urinary bladder epithelium causing activation of specific signaling pathways that lead to chronic increased cell proliferation. This may play a non-epigenetic role in carcinogenesis by increasing the proliferation of initiated cells or increasing the mutational rate

Full Text Available Despite the frequent association of urinary tract infection with vesicoureteral reflux and urinary calculi, since vesicouretal reflux is induced by bladder stones, the coexistence of vesicoureteral reflux and bladder stones is rare. Because of its occurrence in children belonging to poor socioeconomic groups, it is believed to be a deficiency disorder. Most cases of bladder stones occur between the ages of 2 and 5 years. Common clinical presentations of bladder stones include urinary dribbling and enuresis, frequency of micturition, pain during micturition, pelvic pain and hematuria. We report the occurrence of a large bladder stone in a boy, who experienced intermittent lower abdominal pain and urinary incontinence, both during the day and at night. He had been diagnosed with enuresis and treated in pediatric clinics for 1 year. Delayed diagnosis resulted in bladder stone formation. The stone was larger than 2.5 cm and open vesicolithotomy was therefore selected as the best and safest treatment choice. His symptoms disappeared after surgery. Thorough metabolic and environmental evaluations of such cases are required on an individual basis. Bladder stones should be considered as a possible diagnosis in children presenting with urinary incontinence.

Cases of a Borderline Pathology That Can Mimic Bladder Cancer: Primary Amyloidosis of Urinary Bladder

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.

This paper summarizes the engineering development of our lab for endoscopic optical coherence tomography toward the ultimate goal to image bladder micro architecture and to diagnose bladder cancers. To test the utility and potential limitations of OCT setups for bladder tumor diagnosis, we used a rat bladder cancer model to track the morphological changes following tumor growth. Image results are presented, suggesting that OCT is able to differentiate cancerous lesions from inflammatory lesions based on OCT characterizations of epithelial thickness and backscattering changes of bladder tissue.

The concept of peripheral modulation of bladder sensation.

Science.gov (United States)

Eastham, Jane E; Gillespie, James I

2013-01-01

It is recognized that, as the bladder fills, there is a corresponding increase in sensation. This awareness of the volume in the bladder is then used in a complex decision making process to determine if there is a need to void. It is also part of everyday experience that, when the bladder is full and sensations strong, these sensations can be suppressed and the desire to void postponed. The obvious explanation for such altered perceptions is that they occur centrally. However, this may not be the only mechanism. There are data to suggest that descending neural influences and local factors might regulate the sensitivity of the systems within the bladder wall generating afferent activity. Specifically, evidence is accumulating to suggest that the motor-sensory system within the bladder wall is influenced in this way. The motor-sensory system, first described over 100 years ago, appears to be a key component in the afferent outflow, the afferent "noise," generated within the bladder wall. However, the presence and possible importance of this complex system in the generation of bladder sensation has been overlooked in recent years. As the bladder fills the motor activity increases, driven by cholinergic inputs and modulated, possibly, by sympathetic inputs. In this way information on bladder volume can be transmitted to the CNS. It can be argued that the ability to alter the sensitivity of the mechanisms generating the motor component of this motor-sensory system represents a possible indirect way to influence afferent activity and so the perception of bladder volume centrally. Furthermore, it is emerging that the apparent modulation of sensation by drugs to alleviate the symptoms of overactive bladder (OAB), the anti-cholinergics and the new generation of drugs the β 3 sympathomimetics, may be the result of their ability to modulate the motor component of the motor sensory system. The possibility of controlling sensation, physiologically and pharmacologically, by

The aim of this study was to identify predictors of 'intrauterine fetal renal failure' in fetuses with severe congenital lower urinary tract obstruction (LUTO). We undertook a retrospective study of 31 consecutive fetuses with a diagnosis of LUTO in a tertiary Fetal Center between April 2013 and April 2015. Predictors of 'intrauterine fetal renal failure' were evaluated in those infants with severe LUTO who had either a primary composite outcome measure of neonatal death in the first 24 h of life due to severe pulmonary hypoplasia or a need for renal replacement therapy within 7 days of life. The following variables were analyzed: fetal bladder re-expansion 48 h after vesicocentesis, fetal renal ultrasound characteristics, fetal urinary indices, and amniotic fluid volume. Of the 31 fetuses included in the study, eight met the criteria for 'intrauterine fetal renal failure'. All of the latter had composite poor postnatal outcomes based on death within 24 h of life (n = 6) or need for dialysis within 1 week of life (n = 2). The percentage of fetal bladder refilling after vesicocentesis at time of initial evaluation was the only predictor of 'intrauterine fetal renal failure' (cut-off <27 %, area under the time-concentration curve 0.86, 95 % confidence interval 0.68-0.99; p = 0.009). We propose the concept of 'intrauterine fetal renal failure' in fetuses with the most severe forms of LUTO. Fetal bladder refilling can be used to reliably predict 'intrauterine fetal renal failure', which is associated with severe pulmonary hypoplasia or the need for dialysis within a few days of life.

Although our most recent studies have identified Isorhapontigenin (ISO), a novel derivative of stilbene that isolated from a Chinese herb Gnetum cleistostachyum, for its inhibition of human bladder cancer growth, nothing is known whether ISO possesses an inhibitory effect on bladder cancer invasion. Thus, we addressed this important question in current study and discovered that ISO treatment could inhibit mouse-invasive bladder cancer development following bladder carcinogen N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) exposure in vivo We also found that ISO suppressed human bladder cancer cell invasion accompanied by upregulation of the forkhead box class O 1 (FOXO1) mRNA transcription in vitro Accordingly, FOXO1 was profoundly downregulated in human bladder cancer tissues and was negatively correlated with bladder cancer invasion. Forced expression of FOXO1 specifically suppressed high-grade human bladder cancer cell invasion, whereas knockdown of FOXO1 promoted noninvasive bladder cancer cells becoming invasive bladder cancer cells. Moreover, knockout of FOXO1 significantly increased bladder cancer cell invasion and abolished the ISO inhibition of invasion in human bladder cancer cells. Further studies showed that the inhibition of Signal transducer and activator of transcription 1 (STAT1) phosphorylation at Tyr701 was crucial for ISO upregulation of FOXO1 transcription. Furthermore, this study revealed that metalloproteinase-2 (MMP-2) was a FOXO1 downstream effector, which was also supported by data obtained from mouse model of ISO inhibition BBN-induced mouse-invasive bladder cancer formation. These findings not only provide a novel insight into the understanding of mechanism of bladder cancer's propensity to invasion, but also identify a new role and mechanisms underlying the natural compound ISO that specifically suppresses such bladder cancer invasion through targeting the STAT1-FOXO1-MMP-2 axis.

The mechanism of occurrence of sigmoid sinus dehiscence/diverticulum (SSDD) in pulsatile tinnitus (PT) patients remains under debate. Its association with idiopathic intracranial hypertension (IIH) lacks evidence, which is important for therapeutic planning and improving the clinical outcome. This study aimed to evaluate the association between SSDD and IIH by comparing the prevalence of several established imaging features of IIH between PT patients with SSDD and healthy volunteers. Thirty-three unilateral PT patients with SSDD identified on CT images and 33 age- and sex-matched healthy volunteers underwent T1-weighted volumetric magnetic resonance imaging (MRI). The optic nerve, pituitary gland, transverse sinus, and ventricles were assessed. The prevalence of established IIH imaging features was compared between the two groups. Furthermore, the PT patients were divided into two subgroups: PT patients with dehiscence only and PT patients with diverticulum. The same statistical analysis was performed on each pathophysiologic entity respectively. The PT patients with SSDD showed a significantly higher prevalence of empty sella (P < 0.001), flattened posterior sclera (P = 0.001), vertical tortuosity of the optic nerve (P = 0.001), protrusion of the optic nerve (P = 0.006), transverse sinus stenosis (P = 0.011), and distension of the optic nerve sheath (P = 0.000). There were no significant differences between the PT and control groups in the maximum widths of the third and fourth ventricles and the lateral ventricle size. In contrast to controls, the imaging findings persisted in both of pathophysiologic entities, except for transverse sinus stenosis. Several IIH imaging features occur more frequently in PT patients with SSDD than in healthy individuals, which suggests a potential correlation between SSDD with PT and IIH. (orig.)

The possible etiopathogenic factors, symptoms, diagnostic methods, surgical management and complications of the urethral diverticula are reviewed. A retrospective study of the clinical charts with urethral diverticula diagnosis during the period 1986-2006 was carried out. In the last 20 years a total of 19 patients have been treated for this pathology: 15 females and 4 males. Five of the females started with a sensation of vaginal mass; the rest were diagnosed of micturitional (irritative) syndrome, urinary incontinence or urinary infection. In the case of males, 3 of them had a palpable tumour in the penis. The most used diagnostic method was retrograde and voiding cystourethrography; urethrography with double-occlusion balloon catheter was used in 5 cases and urethroscopy in 4 patients; other techniques of image diagnosis like magnetic resonance imaging were necessary for the most complex cases. The treatment was the excision of the diverticulum, except for one of the females who rejected the treatment. The evolution in all treated women was successful, according to follow up 2 years after the treatment. In males, two of them had complex recurrent diverticula. Urethral diverticula are nosologic entities of difficult diagnosis, due to their low prevalence and their unspecific clinic, therefore diagnosis is sometimes incidental. The etiopathogenity is acquired in most cases and its surgical treatment is more challenging in males than in females probably linked to the fact that diverticula appear in urethras with previous surgery, endourologic manipulation or associated injuries.

Bladder exstrophy: An overview of the surgical management

Full Text Available Background: The surgical management of urinary bladder exstrophy is challenging. This paper describes the personal experience in a tertiary care hospital over a period exceeding a quarter of a century. Methods: During the period 1984-2010, 248 patients of the epispadias-exstrophy complex have been treated. The cases of classical bladder exstrophy (n = 210 form the basis of this paper. The stages/procedures used in the surgical reconstruction of bladder exstrophy included bladder closure with anterior abdominal wall reconstruction, bladder neck repair, ureteric reimplantation, epispadias repair and augmentation colocystoplasty in various combinations. Some of these patients had their initial operations done prior to 1984 or in other hospitals. Evaluation methods included, amongst others, clinical evaluation and urodynamic assessment. Eight patients opted out of treatment; 15 patients underwent permanent urinary diversion by either ureterosigmoidostomy or colon conduit. The remaining 187 patients were treated with bladder reconstruction, and of these, 132 patients have had at least one attempt at bladder neck reconstruction with 56 of these patients having undergone an augmentation colocystoplasty. Results: A total of 105 patients had socially acceptable continence: 57 from the bladder neck reconstruction group and 48 from the bladder augmentation group. Further attempts at continence surgery have been offered to the inadequately continent patients. Conclusions: Surgical management of bladder exstrophy demands patience and perseverance. It is possible to provide all patients with socially acceptable continence with bladder neck division and catheterizable continent stoma as the last resort. Urodynamic assessment has emerged as an essential tool in the follow-up evaluation of these patients. Anticholinergic medication with imipramine or oxybutinin is a useful adjunct in the overall management.

Radiotherapy of bladder cancer

Methods of treating bladder cancer include surgery, radiotherapy and chemotherapy, as well as various combinations of these. The author investigated clinically and histopathologically the therapeutic results of preoperative irradiation in cases of bladder cancer. 1. The survival rates (crude survival rates) in forty cases of bladder cancer were 90% after one year, 62.5% after three years and 46% after five years from the treatment. 2. As the result of irradiation, urogram improved in 25%, which was comparatively remarkable in high stage cases. There were no cases of deterioration of urogram findings caused by irradiation. Cystoscopy revealed disappearance or remarkable shrinkage of the tumors in 35% of the total cases and effects of the irradiation was observed not correlated to the stage and grade. 3. With respect to the histopathological changes, the changes became greater as the dosage increased and the higher the stage and grade were the more remarkable tendency was observed. 4. From our clinical observations such as urogram, cystoscopy and histopathologically, we estimated the optimum dosage of preoperative irradiation for bladder cancer is 3000 - 4000 rad. Thus, we concluded that the radiotherapy is effective in reducing both surgical invasion and postoperative recurrence. (author)

The prognosis and treatment of bladder cancer have hardly improved in the last 20 years. Bladder cancer remains a debilitating and often fatal disease, and among the most costly cancers to treat. The generation of informative mouse models has the potential to improve our understanding of bladder cancer progression, as well as impact its diagnosis and treatment. However, relatively few mouse models of bladder cancer have been described and particularly few that develop invasive cancer phenotypes. This review focuses on opportunities for improving the landscape of mouse models of bladder cancer. PMID:25533675

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

Full Text Available Omphalocele, exstrophy of the bladder, imperforate anus and spinal defect (OEIS complex is a rare congenital multisystemic malformation representing unique anomalies. It was first reported in 1978 through a series of cases with an abnormality of body wall development. We are reporting a case of an infant of 36 weeks gestation, with a family history of consanguinity and oral contraceptive pill intake that was discontinued when the mother was 1-month pregnant. The neonatal examination revealed findings that were consistent with OEIS complex along with the presence of genital anomalies. The infant required multi-staged surgical intervention. We conclude that this case report might illustrate some of the possible risk factors and variability of OEIS complex.

Conformal radiotherapy of urinary bladder cancer

Muren, Ludvig Paul; Smaaland, Rune; Dahl, Olav

2004-01-01

Recent advances in radiotherapy (RT) are founded on the enhanced tumour visualisation capabilities of new imaging modalities and the precise deposition of individualised radiation dose distributions made possible with the new systems for RT planning and delivery. These techniques have a large potential to also improve the results of RT of urinary bladder cancer. Major challenges to take full advantage of these advances in the management of bladder cancer are to control, and, as far as possible, reduce bladder motion, and to reliably account for the related intestine and rectum motion. If these obstacles are overcome, it should be possible in the near future to offer selected patients with muscle invading bladder cancer an organ-sparing, yet effective combined-modality treatment as an alternative to radical surgery

Purpose. We have tested a procedure of focal injection of the contrast medium Lipiodol as a fiducial marker for image-guided boost of the tumor in bladder cancer radiotherapy (RT). In this study, we have evaluated the feasibility and the safety of the method as well as the inter- and intra-fraction shift of the bladder tumor. Materials and methods. Five patients with muscle invasive urinary bladder cancer were included in the study. Lipiodol was injected during flexible cystoscopy into the submucosa of the bladder wall at the periphery of the tumor or the post resection tumor-bed. Cone-beam CT (CBCT) scans were acquired daily throughout the course of RT. Results. Lipiodol demarcation of the bladder tumor was feasible and safe with only a minimum of side effects related to the procedure. The Lipiodol spots were visible on CT and CBCT scans for the duration of the RT course. More than half of all the treatment fractions required a geometric shift of 5 mm or more to match on the Lipiodol spots. The mean intra-fraction shift (3D) of the tumor was 3 mm, largest in the anterior-posterior and cranial-caudal directions. Conclusion. This study demonstrates that Lipiodol can be injected into the bladder mucosa and subsequently visualized on CT and CBCT as a fiducial marker. The relatively large inter-fraction shifts in the positions of Lipiodol spots compared to the intra-fraction movement indicates that image-guided RT based on radio-opaque markers is important for RT of the bladder cancer tumor.

Full Text Available OBJECTIVE: Propose a new experimental model of bladder instability in rabbits after partial bladder obstruction. MATERIALS AND METHODS: Thirty North Folk male rabbits, weighting 1,700 to 2,820 g (mean: 2,162 g were studied. The animals were distributed in 2 experimental groups, formed by 15 rabbits each: Group 1 - clinical control. In this group there was no surgical intervention; Group 2 - bladder outlet obstruction. In this group, after anesthetizing the animal, urethral cannulation with Foley catheter 10F was performed and then an adjustable plastic bracelet was passed around the bladder neck. It was then adjusted in order to not constrict the urethra. The following parameters were studied in M1 - pre-operative period; M2 - 4 weeks post-operatively moments: 1- urine culture; 2- cystometric study; 3- serum creatinine and BUN. RESULTS: Bladder weight was 2.5 times larger in the group with obstruction than in the control group. Cystometric evaluation showed a significant increase in maximal vesical volume in the final moment at Group G2. However, there was no statistically significant difference among the groups studied. There was no statistically significant difference between maximal detrusor pressure and vesical compliance in the different moments or in the studied groups. There was an absence of uninhibited detrusor contractions in all the animals in group 1, and involuntary contractions were detected in 93% of group 2 animals. There was no significant variation in BUN and serum creatinine either among the groups or in the same group. CONCLUSIONS: We observed in the group with obstruction a bladder weight 2.5 higher than normal bladders. We detected involuntary contractions in 93% of the animals in group 2, establishing this experimental model as appropriate to secondary bladder instability and partial bladder outlet obstruction.

We investigated the characteristics of bladder mechanosensitive single-unit afferent activities (SAAs) in rats with a bladder outlet obstruction (BOO) and their relationship with bladder microcontractions. Male Wistar rats were divided into Sham and BOO groups. Four or 10 days after the surgery, rats were anesthetized with urethane. The SAAs of Aδ- or C-fibers from the L6 dorsal roots were recorded during bladder filling. The BOO group showed a higher number of microcontractions and lower SAAs of Aδ-fibers compared with those of the Sham group. These findings were significant at day 10 post-operatively. In contrast, SAAs of C-fibers were not significantly different between the groups at either day 4 or 10. In the BOO group at day 10, the SAAs of both Aδ- and C-fibers at the "ascending" phase of microcontractions were significantly higher than those at the other phases (descending or stationary), and a similar tendency was also observed at day 4. Taken together, during bladder filling, the bladder mechanosensitive SAAs of Aδ-fibers were attenuated, but SAAs of both Aδ- and C-fibers were intermittently enhanced by propagation of microcontractions.

Full Text Available Zenker's diverticulum arises in the posterior wall of the pharynx, above the cricopharyngeal muscle, secondary to a functional cricopharyngeal disorder. We describe our experience with the management of Zenker's diverticulum from 1985 to this day in a third-level hospital. We review clinical data from 27 patients (78% males with a mean age of 60.4 years. The most common clinical manifestations were dysphagia, regurgitation, syalorrhea, cough, and weight loss. All cases were diagnosed using an esophagogram. A diverticulectomy with cricopharingeal myotomy was performed in 74% of patients. Complications developed in 5 cases (21%, and the recurrence rate was 4% (1 of 3 cases, where myotomy was not performed.

Zenker's diverticulum (ZD) may be misdiagnosed on conventional ultrasound as a thyroid nodule or other lesion. A barium esophagram is usually used to confirm the diagnosis; however, this procedure exposes the patient to radiation. The aim of this study was to evaluate the feasibility of using swallow contrast-enhanced ultrasound (swallow-CEUS) to diagnose ZD. Ten consecutive patients with ZD (7 men and 3 women, aged 67 ± 11 y) were included in the study. In 4 patients, ZD was incidentally found on head and neck ultrasound, and in 6 patients, ZD was suspected because of dysphagia. All lesions could be detected on conventional ultrasound before swallow-CEUS. Ten healthy volunteers (8 men and 2 women, aged 60 ± 12 y) were chosen as a control group. Written informed consent was obtained. With the patient in the sitting or upright position, conventional ultrasound was performed first to image the lesion, then the patient was asked to swallow ultrasound contrast agent (UCA) (2-4 drops of SonoVue diluted with about 200 mL of tap water). Transity of the contrast agent in the esophagus was imaged with CEUS. Retention of the UCA in the diverticulum was monitored for at least 3 min. All patients underwent a barium esophagram as the gold standard. Swallow-CEUS revealed that in all patients (100%), the UCA was transported from the pharynx to the esophagus while the patient swallowed. ZD appeared as a pouch-shaped structure at the posterior pharyngo-esophageal junction that retained UCA longer than 3 min. The barium esophagram confirmed the diagnosis of ZD in all patients. For the 10 volunteers, no abnormal structure (retaining UCA) was detected during or after swallowing of UCA. With the advantages of no radiation and bedside availability, swallow-CEUS may become a method of choice in confirmation of the diagnosis of ZD, especially when ZD is suspected on conventional ultrasound.

Vaginal calculus is a rare disorder which has been reported in association with urethral diverticulum, urogenital sinus anomaly, bladder exstrophy and the tension-free vaginal tape (TVT) procedure. We report a 42-year-old woman who presented with persistent, intractable urinary tract infection (UTI) following a TVT procedure. Cystoscopy demonstrated an eroded tape with the formation of a bladder calculus, and the patient underwent laser cystolithotripsy and cystoscopic resection of the tape. Following this procedure, her UTI completely resolved and she remained asymptomatic for several years. Seven years later she presented with a solid vaginal mass. Pelvic examination followed by transvaginal ultrasonography and magnetic resonance imaging demonstrated a large vaginal calculus located at the lower third of the anterior vaginal wall adjacent to the bladder neck. This video presents the transvaginal excision and removal of the vaginal calculus.

Purpose: To assess the clinical utility of X-ray volume imaging (XVI) for verification of bladder radiotherapy and to quantify geometric error in bladder radiotherapy delivery. Methods and Materials: Twenty subjects undergoing conformal bladder radiotherapy were recruited. X-ray volume images and electronic portal images (EPIs) were acquired for the first 5 fractions and then once weekly. X-ray volume images were co-registered with the planning computed tomography scan and clinical target volume coverage assessed in three dimensions (3D). Interfraction bladder volume change was described by quantifying changes in bladder volume with time. Bony setup errors were compared from both XVI and EPI. Results: The bladder boundary was clearly visible on coronal XVI views in nearly all images, allowing accurate 3D treatment verification. In 93.5% of imaged fractions, the clinical target volume was within the planning target volume. Most subjects displayed consistent bladder volumes, but 25% displayed changes that could be predicted from the first three XVIs. Bony setup errors were similar whether calculated from XVI or EPI. Conclusions: Coronal XVI can be used to verify 3D bladder radiotherapy delivery. Image-guided interventions to reduce geographic miss and normal tissue toxicity are feasible with this technology

Full Text Available The chronic urinary tract infection (UTI is a risk factor that worsens a natural course of bladder tumors. Using of probiotics, possessing antagonistic influence on pathogenic microflora and immunocorrection effect, for preventive maintenance and treat¬ment of a chronic UTI in bladder tumor patients is an actual and perspective direction. The goal of the research was studying antimicrobial and anti-inflammatory effect of a single bladder instillation of either lactobacilli or aerococci in bladder tumor patients. In the preoperative period a single bladder instillation with either lactobacterin or a-bacterin preparation to 35 bladder tumor patients was done. Bacteriuria, leucocyturia, lactobacilli and aerococci count in urine were measured before and in 1, 3, 6 and 24 hours after instillation. Decrease in bacteriuria level in both groups of patients was revealed. Lactobacilli and aerococci count in urine gradually decreased up to complete elimination in 24 hours (in 1 patient who received lactobacterin (12,5 % and in 9 patients who received a-bacterin. (40,9 %. Leucocyturia study did not show statistically confidence dynamics throughout the observation period in both groups. Thus, bladder instillation with lactobacterin or a-bacterin leads to suppression of uropathogenic microflora in bladder tumor patients; in the majority of patients spontaneous elimination of lactobacilli and aerococci occurs within 24 hours.

Full Text Available Objective: to evaluate patients treated with primary bladder adenocarcinoma at our institution. Methods: A review of 30 patients diagnosed with bladder adenocarcinoma at a single institution from 1994 of 2005 was undertaken. Cases of primary bladder adenocarcinoma were retrospectively evaluated. Rresults: Out of 490 patients with bladder carcinoma, 30 had bladder adenocarcinoma: 22 metastatic tumors, eight (1.6% primary adenocarcinoma. Of these, three (0.6% were primary non-urachal and five (1.0% were urachal adenocarcinoma. All patients were men with mean age of 55.8 years (range 37-83. Dysuria and hematuria were the main symptoms reported. Of the total, four patients had cancer-related mortality. Cconclusion: Primary bladder adenocarcinoma is a rare neoplasm, observed in 1.6% patients with bladder malignancies. Late diagnosis limits therapeutic possibilities. Partial cystectomy seems to have unsatisfactory results and radical cystectomy, although remains as the gold standard, have no proven efficacy. New methods of adjuvant treatment must be studied to improve treatment outcomes, as high mortality is observed despite treatment.

We applied confocal Raman spectroscopy to investigate 12 normal bladder tissues and 30 tumor tissues, and then depicted the spectral differences between the normal and the tumor tissues and the potential canceration mechanism with the aid of the high-performance liquid chromatographic (HPLC) technique. Normal tissues were demonstrated to contain higher tryptophan, cholesterol and lipid content, while bladder tumor tissues were rich in nucleic acids, collagen and carotenoids. In particular, β-carotene, one of the major types of carotenoids, was found through HPLC analysis of the extract of bladder tissues. The statistical software SPSS was applied to classify the spectra of the two types of tissues according to their differences. The sensitivity and specificity of 96.7 and 66.7% were obtained, respectively. In addition, different layers of the bladder wall including mucosa (lumps), muscle and adipose bladder tissue were analyzed by Raman mapping technique in response to previous Raman studies of bladder tissues. All of these will play an important role as a directive tool for the future diagnosis of bladder cancer in vivo.

The transurethral resection of bladder tumor (TURBT) remains the most widely used method in the surgical treatment of the non-muscle invasive bladder tumor (NMIBT). Despite its popularity, the laser technique has been widely used in urology as an alternative, via the application of transurethral laser enucleation of bladder tumor. The aim of the present study was to compare the efficacy and feasibility between transurethral laser enucleation and transurethral resection of bladder tumor. A systematic search of the following databases was conducted: PubMed, Wed of Science, Cochrane Library, EMBASE, Google scholar, and Medline. The search included studies up to the 1st of January 2017. The outcomes of interest that were used in order to assess the two techniques included operation time, catheterization time, hospitalization time, obturator nerve reflex, bladder perforation, bladder irritation, 24-month-recurrence rate, and the postoperative adjuvant intravesical chemotherapy. A total of 13 trials with 2012 participants were included, of which 975 and 1037 underwent transurethral laser enucleation and transurethral resection of bladder tumor, respectively. No significant difference was noted in the operation time between the two groups, although significant differences were reported for the variables catheterization time, hospitalization time, obturator nerve reflex, bladder perforation, bladder irritation, and 24-month-recurrence rate. In the mitomycin and epirubicin subgroups, no significant differences were observed in the laser enucleation and TURBT methods with regard to the 24-month-recurrence rate. The laser enucleation was superior to TURBT with regard to the parameters obturator nerve reflex, bladder perforation, catheterization time, hospitalization time, and 24-month-recurrence rate. Moreover, laser enucleation can offer a more accurate result of the tumor's pathological stage and grade.

This report describes the clinical findings and diagnostic images of a traumatic intrathoracic tracheal avulsion with a tracheal diverticulum in a cat. Furthermore, a complete description of the tracheal resection and anastomosis using one-lung ventilation (OLV) with total and partial intravenous anesthesia is made. A 3-year-old neutered male domestic shorthair cat weighing 6.8 kg was presented to the University Teaching Hospital for evaluation of increased respiratory noise 3 months following unknown trauma. Approximately 12 weeks prior to presentation, the cat had been seen by the primary care veterinarian for respiratory distress. At that time, the cat had undergone a tracheal ballooning procedure for a distal tracheal stricture diagnosed by tracheoscopy. The tracheal ballooning had provided only temporary relief. At presentation to our institution, the cat had increased respiratory effort with harsh upper airway noise auscultated during thoracic examination. The remainder of the physical examination was normal. Diagnostics included a tracheoscopy and a thoracic computed tomographic examination. The cat was diagnosed with tracheal avulsion, pseudotrachea with a tracheal diverticulum, and stenosis of the avulsed tracheal ends. Surgical correction of the tracheal stricture via a thoracotomy was performed using OLV with total and partial intravenous anesthesia. The cat recovered uneventfully and at last follow-up was active and doing well. This case report describes OLV using standard anesthesia equipment that is available at most private practices. Furthermore, this case describes the computed tomographic images of the intrathoracic tracheal avulsion and offers a positive outcome for tracheal resection and anastomosis. © Veterinary Emergency and Critical Care Society 2015.

Full Text Available Sepsis-associated encephalopathy (SEA is a diffuse brain dysfunction secondary to the systemic response to infection and is associated with high mortality rate. We report a 4-year-old boy with SEA. He presented with abdominal pain and vomiting. On the second day of admission, he developed consciousness disturbance with impaired attention, confusion and delirium. Routine laboratory tests, brain magnetic resonance imaging and cerebrospinal fluid examination were normal. Electroencephalography (EEG showed high-voltage slow wave activity on the right hemisphere with epileptiform discharge. He immediately underwent surgery and a torsed, gangrenous Meckel%u2019s diverticulum with extension of ischemia to adjacent small bowel was seen and resected. His consciousness had become normal by the third day and he was discharged without any sequela. To overcome a poor prognosis in patients with SEA, the early recognition of the symptoms of SEA and also appropriate treatment of the underlying cause are essential.

Suburothelial Bladder Contraction Detection with Implanted Pressure Sensor.

Directory of Open Access Journals (Sweden)

Steve J A Majerus

Full Text Available Managing bladder pressure in patients with neurogenic bladders is needed to improve rehabilitation options, avoid upper tract damage, incontinence, and their associated co-morbidities and mortality. Current methods of determining bladder contractions are not amenable to chronic or ambulatory settings. In this study we evaluated detection of bladder contractions using a novel piezoelectric catheter-free pressure sensor placed in a suburothelial bladder location in animals.Wired prototypes of the pressure monitor were implanted into 2 nonsurvival (feline and canine and one 13-day survival (canine animal. Vesical pressures were obtained from the device in both suburothelial and intraluminal locations and simultaneously from a pressure sensing catheter in the bladder. Intravesical pressure was monitored in the survival animal over 10 days from the suburothelial location and necropsy was performed to assess migration and erosion.In the nonsurvival animals, the average correlation between device and reference catheter data was high during both electrically stimulated bladder contractions and manual compressions (r = 0.93±0.03, r = 0.89±0.03. Measured pressures correlated strongly (r = 0.98±0.02 when the device was placed in the bladder lumen. The survival animal initially recorded physiologic data, but later this deteriorated. However, endstage intraluminal device recordings correlated (r = 0.85±0.13 with the pressure catheter. Significant erosion of the implant through the detrusor was found.This study confirms correlation between suburothelial pressure readings and intravesical bladder pressures. Due to device erosion during ambulatory studies, a wireless implant is recommended for clinical rehabilitation applications.

One of the commonest forms of orthotopic bladder substitution for bladder cancer surivors, used in our institute, is the use of ileocecal segment. Sometimes, the need for Indiana pouch heterotropic continent diversion arises. Aim: To compare the long-term effect of orthotopic ileocecal bladder and heterotropic Indiana pouch following radical cystectomy in bladder cancer patients. Patients and methods: Between January 2008 and December 2011, 91 patients underwent radical cystectomy/anterior pelvic exentration and ortho topic ileocecal bladder reconstruction (61 patients) and Indiana pouch (30 patients), when orthotopic diversion could not be technically or oncologically feasible. Results: Convalescence was uneventful in most patients. All minor and major urinary leakage cases, in both diversions groups, where successfully conservatively treated. Only one patient in the ileocecal group with major urinary leak required re-exploration with successful revision of uretro-colonic anastomosis. Only one patient in the Indiana pouch group had accidentally discovered sub-centimetric stone, which was simply expelled. The overall survival proportion of ileocecal group was 100% compared to 80% in the Indiana pouch group (p < 0.001). The disease free survival proportion of ileocecal group was 90.8% compared to 80% in the Indiana pouch group (p = 0.076). Effective comparative daytime and nighttime urinary continence as well as renal function deterioration were not statistically significant between both reconstruction types. Conclusion: Both ileocecal bladder and Indiana pouch are safe procedures in regard to long-term effects over kidney function following radical cystectomy

This article provides a review of bladder cancer etiology, diagnosis, and management for WOC nurses. Bladder cancer incidence continues to rise yearly in the United States, and patients with bladder cancer comprise some of the most challenging cases in urologic oncology. Nurses are involved with all aspects of the processes of care for the patient with bladder cancer, from initial diagnosis and treatment to postsurgical care and follow-up. For nonmuscle invasive bladder cancer, treatment includes transurethral resection followed by intravesical chemotherapy or immunotherapy to prevent recurrence or progression. Radical cystectomy along with chemotherapy protocols provides a survival advantage for muscle invasive bladder cancer, although the timing of chemotherapy remains controversial. Numerous factors are considered when determining the type of urinary diversion used at the time of radical cystectomy, but patient, family, surgeon, and nursing input are essential for preserving an optimal health-related quality of life and reducing morbidity. Patients with metastatic bladder cancer are generally treated with a cisplatin-based chemotherapy but continue to have a poor prognosis. Newer therapies involving novel molecular-targeted agents provide hope for the future for patients with metastatic disease.

In Parkinson's disease (PD) the urinary dysfunction manifests primarily with symptoms of overactive bladder (OAB). The OAB questionnaire (OAB-q) is a measure designed to assess the impact of OAB symptoms on health-related quality of life. In this study, we quantified the urinary symptoms in a large cohort of PD patients by using the OAB-q short form. Possible correlations between the OAB-q and clinical features were tested. Three hundred and two PD patients were enrolled in the study. Correlations between the OAB-q and sex, age, Unified Parkinson's Disease Rating Scale part III (UPDRS-III), Hoehn-Yahr (H-Y) staging, disease duration, and treatment were analyzed. Data were compared with a large cohort of 303 age-matched healthy subjects. The OAB-q yielded significantly higher scores in PD patients than in healthy subjects. In the group of PD patients, all the variables tested were similar between men and women. Pearson's coefficient showed a significant correlation between mean age, disease duration, mean OAB-q scores, UPDRS-III scores, and H-Y staging. A multiple linear regression analysis showed that OAB-q values were significantly influenced by age and UPDRS-III. No statistical correlations were found between OAB-q scores and drug therapy or the equivalent levodopa dose, whilst the items relating to the nocturia symptoms were significantly associated with the equivalent levodopa dose. Our findings suggest that bladder dysfunction assessed by OAB-q mainly correlates with UPDRS-III scores for severity of motor impairment, possibly reflecting the known role of the decline in nigrostriatal dopaminergic function in bladder dysfunction associated with PD and patients' age. Our study also suggests that the OAB-q is a simple, easily administered test that can objectively evaluate bladder function in patients with PD.

The aim of this study is to access the feasibility, toxicity profile, and tumour outcome of an organ preservation curative approach in non-metastatic muscle-invasive bladder cancer. A retrospective analysis was conducted on patients affected by M0 bladder cancer, who refused cystectomy and were treated with a curative approach. The standard bladder preservation scheme included maximal transurethral resection of bladder tumour (TURBT) and combination of radiotherapy and platin-based chemotherapy, followed by endoscopic evaluation, urine cytology, and instrumental evaluation. Thirteen patients fulfilled the inclusion criteria. TNM stage was cT2cN0M0 and cT2cNxM0, in 12 and one patients, respectively. All patients had transitional cell cancer. Twelve patients completed the whole therapeutic programme (a bimodal treatment without chemotherapy for one patient). Median follow-up is 36 months. None of the patients developed severe urinary or intestinal acute toxicity. In 10 patients with a follow-up > 6 months, no cases of severe late toxicity were observed. Response evaluated in 12 patients included complete response and stable disease in 11 patients (92%), and one patient (8%), respectively. At the time of data analysis (March 2016), 10 patients (77%) are alive with no evidence of disease, two patients (15%) died for other reasons, and one patient has suspicious persistent local disease. The trimodality approach, including maximal TURBT, radiotherapy, and chemotherapy for muscle-invasive bladder cancer, is well-tolerated and might be considered a valid and feasible option in fit patients who refuse radical cystectomy.

The identification of potential tumor markers will help improve therapeutic planning and patient management. Thrombomodulin (TM) is a sensitive urothelial marker. TM was reported to be one of the endogenous anti-metastatic factors and has diagnostic and prognostic values for the progression of carcinoma. In the present study, we examine the role of TM in bladder cancer. We studied the role of TM in tumor behavior and related signaling pathways in vitro using the human bladder cancer cell lines HT1376, HT1197, J82 and T24, and in vivo using animal models. We also selected clinical specimens from 100 patients with bladder cancer for immunohistochemical staining to evaluate the predictive capacity of TM in tumor invasiveness. The data revealed that positive immunoreactivity for TM was inversely correlated with clinical stage and DNA methyltransferase 1 immunoreactivity. Decreased TM expression could predict the aggressive tumor growth and advanced clinical stage in bladder cancer. When TM was inhibited, tumor growth rate and invasion ability were augmented in vitro and in vivo. The underlying changes included increased cell proliferation, enhanced epithelial-mesenchymal transition (EMT) and angiogenesis. Moreover, inhibition of NF-κB activation significantly increased TM expression and attenuated tumor aggressiveness in bladder cancer. TM plays an important role in bladder cancer tumor aggressiveness in vitro and in vivo and is a clinically significant predictor that may represent a suitable therapeutic target for bladder cancer

A 81-year-old male was referred to our emergency outpatient unit due to acute renal failure. The level of serum creatinine was 276 μmol/l. A CT scan showed bilateral hydronephroureter, large bladder stone (7 cm × 6 cm × 6 cm) and bladder wall thickness. He was diagnosed as post renal failure due to bilateral hydronephroureter. Large bladder stone is thought to be the cause of bilateral hydronephroureter and renal failure. To improve renal failure, we performed open cystolithotomy and urethral catheterization. Three days after the surgery, the level of serum creatinine decreased to 224 μmol/l. He was discharged from our hospital with uneventful course. Bladder calculus is thought to be a rare cause of renal failure. We summarize the characteristics of bladder calculus causing renal failure. We should keep that long-term pyuria and urinary symptom, and repeated urinary tract infection can cause huge bladder calculus and renal failure in mind.

Marić Predrag

2016-01-01

Full Text Available Introduction. Pheochromocytoma of the urinary bladder is a rare tumor and presents less than 0.06% of all urinary bladder tumors. Case report. We presented a 49-year-old female patient with a history of daily paroxysmal hypertension accompanied with flushing of the face and upper chest, palpitations and excessive sweating prior to micturition. Ultrasonography reported a 3 cm bladder wall tumor. The 131I-metaiodobenzylguanidine (131I-MIBG scan showed a pathological isotope accumulation in the projection of the bladder. The patient underwent a partial cystectomy. One year following the operation the patient was normotensive and without recurrence. Conclusion. The most efficient treatment option for bladder pheochromocytoma is surgical resection. The most important fact in the diagnostics is suspicion on this rare condition.

Congenital symmastia revisited

Symmastia is defined as medial confluence of the breast. The term 'symmastia' is modified from Greek (syn meaning 'together', and mastos meaning 'breast') and was first presented by Spence et al. in 1983. Two forms of symmastia exist: an iatrogenic and a congenital version. Congenital symmastia...... is a rare condition in which web-like soft tissue traverses the sternum to connect the breasts medially. The literature on congenital symmastia is limited, few cases have been published, and knowledge about ideal treatment is still insufficient....

Complications of bladder distension during retrograde urethrography.

Science.gov (United States)

Barsanti, J A; Crowell, W; Losonsky, J; Talkington, F D

1981-05-01

A severe, ulcerative cystitis that resulted in macroscopic hematuria occurred in 8 of 20 healthy dogs undergoing a series of diagnostic tests. Four of the remaining 12 dogs had mild bladder lesions consisting of submucosal edema and hemorrhage. Nine of the 20 dogs developed urinary tract infection after the procedures. These complications seemed associated with the radiographic technique of retrograde urethrography performed when the urinary bladder was distended. To test this hypothesis, retrograde urethrography was performed on 5 additional dogs. With the bladder undistended, no complications occurred. However, distention of these same dogs' bladders for 1 minute or less with sterile lactated Ringer's solution administered through a Foley catheter in the penile urethra resulted in a macroscopic hematuria in all 5 dogs which persisted for 24 hours. A microscopic hematuria continued for 5 days. One dog developed a bacterial urinary tract infection. A severe fibrinopurulent cystitis was present at necropsy of 2 dogs 2 days after distention. The morphologic changes in the bladder gradually diminished over 7 days, but mild submucosal edema and hemorrhage were still present when 2 dogs were necropsied, 7 days after distention. These studies indicated that retrograde urethrography in dogs may be complicated by hemorrhagic cystitis and urinary tract infection if performed with urinary bladder distention.

Bladder metastases of appendiceal mucinous adenocarcinoma: a case presentation

2010-02-01

Full Text Available Abstract Background 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. Case Presentation 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. Conclusions 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.

Many epidemiological and experimental studies report a strong role of chemical carcinogens in the etiology of bladder cancer. However, the involvement of heavy metals in tumourigenesis of urothelial carcinoma of the bladder has been poorly investigated. Therefore, the aim of this study was to examine the relationship between chromium (Cr) and bladder cancer. Chromium concentration in two 36-sample series of bladder cancer tissue and sera from patients with this neoplasm were matched with those of a control group. The amount of trace elements in every tissue sample was determined using atomic absorption spectrometry. This was correlated with tumour stage. While the median chromium concentration levels reached statistically higher values in the bladder cancer tissue, compared with the non-cancer tissue (99.632ng/g and 33.144ng/g, respectively; p<0.001), the median Cr levels in the sera of the patients with this carcinoma showed no statistical difference when compared to those of the control group (0.511μg/l and 0.710μg/l, respectively; p=0.408). The median levels of Cr in the bladder tissue, depending on the stage of the tumour, compared with the tissue without the neoplasm, observed the same relationship for both non-muscle invasive and muscle-invasive tumours (p<0.001 and p<0.01, respectively). This study shows that patients with urothelial carcinoma of the bladder had higher tissue Cr levels than people without tumour, while no difference was found in the Cr serum levels between the two groups of patients under investigation.

The association between pediatric cancer and congenital abnormalities is well known but, there is no exclusive data on the neonatal period and the underlying etiopathogenic mechanisms are unknown. First, to analyze the frequency of neonatal tumours associated with congenital abnormalities; and second, to comment on the likely etiopathogenic hypotheses of a relationship between neonatal tumours and congenital abnormalities. Historical series of neonatal tumours from La Fe University Children's Hospital in Valencia (Spain), from January 1990 to December 1999. Histological varieties of neonatal tumours and associated congenital abnormalities were described. A systematic review of the last 25 years was carried out using Medline, Cancerlit, Index Citation Science and Embase. The search profile used was the combination of "neonatal/congenital-tumors/cancer/neoplasms" and "congenital malformations/birth defects". 72 neonatal tumours were identified (2.8% of all pediatric cancers diagnosed in our hospital) and in 15 cases (20.8%) there was some associated malformation, disease or syndrome. The association between congenital abnormalities and neonatal tumours were: a) angiomas in three patients: two patients with congenital heart disease with a choanal stenosis, laryngomalacia; b) neuroblastomas in two patients: horseshoe kidney with vertebral anomalies and other with congenital heart disease; c) teratomas in two patients: one with cleft palate with vertebral anomalies and other with metatarsal varus; d) one tumour of the central nervous system with Bochdaleck hernia; e) heart tumours in four patients with tuberous sclerosis; f) acute leukaemia in one patient with Down syndrome and congenital heart disease; g) kidney tumour in one case with triventricular hydrocephaly, and h) adrenocortical tumour: hemihypertrophy. The publications included the tumours diagnosed in different pediatric periods and without unified criteria to classify the congenital abnormalities. Little data

Urinary Bladder Leiomyosarcoma: Primary Surgical Treatment

Directory of Open Access Journals (Sweden)

Hakim Slaoui

2014-07-01

Full Text Available 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.

Objective: Preliminarily analysis of the MRI features of bladder leiomyoma. Methods: The MRI manifestations were analyzed with review of previous released literatures in a case of bladder leiomyoma, which was confirmed by pathology. Results: The lesion manifested homogeneous intermediate signal intensity both on non-enhanced T 1 WI and T 2 WI, and intermediate enhancement on contrast enhanced T 1 WI. There was no pedicle on the tumor and the tumor-bladder junction had an acute angle, indicating its benign nature. Conclusion: Non-epithelial tumor has characteristic signals in non-enhanced MRI, in which the leiomyoma of bladder is the most frequent benign neoplasm encountered. Considering enhanced MRI findings, the morphology and growth pattern of the tumor, accurate diagnosis can be made in some cases of bladder leiomyoma, providing valuable informations for surgical planning.

Bladder cancer is a common cancer worldwide and its incidence continues to increase. There are approximately 261,000 cases of bladder cancer resulting in 115,000 deaths annually. This study aimed to integrate bladder cancer genome copy number variation information and bladder cancer gene transcription level expression data to construct a causal-target module network of the range of bladder cancer-related genomes. Here, we explored the control mechanism underlying bladder cancer phenotype expression regulation by the major bladder cancer genes. We selected 22 modules as the initial module network to expand the search to screen more networks. After bootstrapping 100 times, we obtained 16 key regulators. These 16 key candidate regulatory genes were further expanded to identify the expression changes of 11,676 genes in 275 modules, which may all have the same regulation. In conclusion, a series of modules associated with the terms 'cancer' or 'bladder' were considered to constitute a potential network.

Full Text Available Purpose. We evaluated the effect of sulforaphane (SFN treatment on the function and changes of expression of Nrf2-ARE pathway in the bladder of rats with bladder outlet obstruction (BOO. Materials and Methods. A total of 18 male Sprague-Dawley rats at age of 8 weeks were divided into 3 groups (6 of each: the sham operated group, the BOO group, and the BOO+SFN group. We examined histological alterations and the changes of oxidative stress markers and the protein expression of the Nrf2-ARE pathway. Results. We found that SFN treatment could prolong micturition interval and increase bladder capacity and bladder compliance. However, the peak voiding pressure was lower than BOO group. SFN treatment can ameliorate the increase of collagen fibers induced by obstruction. SFN treatment also increased the activity of SOD, GSH-Px, and CAT compared to the other groups. The level of bladder cell apoptosis was decreased in BOO rats with SFN treatment. Moreover, SFN could reduce the ratio of Bax/Bcl-2 expression. Furthermore, SFN could activate the Nrf2 expression with elevation of its target antioxidant proteins. Conclusions. The sulforaphane-mediated decrease of oxidative stress and activation of the Nrf2-ARE pathway may ameliorate bladder dysfunction caused by bladder outlet obstruction.

In the Nordeste de Amaralina suburb of Salvador Bahia, Brazil, 47 of 285 pregnant women surveyed had complement fixing antibodies to Trypanosoma cruzi. At delivery T. cruzi was detected in one of 17 placentas from the sero-positive women. The offspring of this case were premature twins and T. cruzi was detected in the peripheral blood of each before death. At autopsy the gastro-intestinal tract and urinary bladder of both were severely affected. Immunofluorescence tests on cord sera, including the single case with T. cruzi in the placenta, were negative for IgM antibodies to T. cruzi. The mother of the infected twins and three of her living children, who were born and have resided in the city, were also infected with T. cruzi. Although the children had visited an area endemic for Chagas's disease for short periods, the mode of transmission in this family may have been transplacental. The value of the immunofluorescence test in the diagnosis of congenital Chagas's disease is discussed.

In post-prostatectomy radiotherapy to the prostatic bed, consistent bladder volume is essential to maintain the position of treatment target volume. We assessed the differences between bladder volume readings from a portable bladder scanner (BS-V) and those obtained from planning CT (CT-V) or cone-beam CT (CBCT-V). Interfraction bladder volume variation was also determined. BS-V was recorded before and after planning CT or CBCT. The percentage differences between the readings using the two imaging modalities, standard deviations and 95% confidence intervals were determined. Data were analysed for the whole patient cohort and separately for the older BladderScan™ BVI3000 and newer BVI9400 model. Interfraction bladder volume variation was determined from the percentage difference between the CT-V and CBCT-V. Treatment duration, incorporating the time needed for BS and CBCT, was recorded. Fourteen patients were enrolled, producing 133 data sets for analysis. BS-V was taken using the BVI9400 in four patients (43 data sets). The mean BS-V was 253.2 mL, and the mean CT-V or CBCT-V was 199 cm(3). The mean percentage difference between the two modalities was 19.7% (SD 42.2; 95%CI 12.4 to 26.9). The BVI9400 model produced more consistent readings, with a mean percentage difference of -6.2% (SD 27.8; 95% CI -14.7 to -2.4%). The mean percentage difference between CT-V and CBCT-V was 31.3% (range -48% to 199.4%). Treatment duration from time of first BS reading to CBCT was, on average, 12 min (range 6-27). The BS produces bladder volume readings of an average 19.7% difference from CT-V or CBCT-V and can potentially be used to screen for large interfraction bladder volume variations in radiotherapy to prostatic bed. The observed interfraction bladder volume variation suggests the need to improve bladder volume consistency. Incorporating the BS into practice is feasible. © 2014 The Royal Australian and New Zealand College of Radiologists.

Dall’Era, Marc A; Cheng, Liang; Pan, Chong-Xian

2012-01-01

The current standard treatment for muscle-invasive nonmetastatic bladder cancer is neoadjuvant platinum-based chemotherapy followed by radical cystectomy. However, neoadjuvant chemotherapy is not widely accepted even with level 1 evidence. Adjuvant chemotherapy should be discussed if patients have not received neoadjuvant chemotherapy before surgery and have high-risk pathologic features. Although not considered standard of care, bladder-sparing therapy can be considered for highly selected patients and for those medically unfit for surgery. Even though there are no level 1 data, the treatment outcomes for highly select patients given bladder-sparing therapy appear promising, with many patients retaining a functional bladder. Personalized chemotherapy is currently being actively pursued to target the underlying molecular changes and tailor to individual needs. PMID:22845409

Foley catheters are assumed to drain the bladder to completion. Drainage characteristics of Foley catheter systems are poorly understood. To investigate unrecognized retained urine with Foley catheter drainage systems, bladder volumes of hospitalized patients were measured with bladder scan ultrasound volumetrics. Additionally, an in vitro bench top mock bladder and urinary catheter system was developed to understand the etiology of such residual volumes. A novel drainage tube design that optimizes indwelling catheter drainage was also designed. Bedside bladder ultrasound volumetric studies were performed on patients hospitalized in ward and intensive care unit. If residual urine was identified the drainage tubing was manipulated to facilitate drainage. An ex vivo bladder-urinary catheter model was designed to measure flow rates and pressures within the drainage tubing of a traditional and a novel drainage tube system. A total of 75 patients in the intensive care unit underwent bladder ultrasound volumetrics. Mean residual volume was 96 ml (range 4 to 290). In 75 patients on the hospital ward mean residual volume was 136 ml (range 22 to 647). In the experimental model we found that for every 1 cm in curl height, obstruction pressure increased by 1 cm H2O within the artificial bladder. In contrast, the novel spiral-shaped drainage tube demonstrated rapid (0.5 cc per second), continuous and complete (100%) reservoir drainage in all trials. Traditional Foley catheter drainage systems evacuate the bladder suboptimally. Outflow obstruction is caused by air-locks that develop within curled redundant drainage tubing segments. The novel drainage tubing design eliminates gravity dependent curls and associated air-locks, optimizes flow, and minimizes residual bladder urine.

The aim of this study was to investigate modifiable lifestyle factors of smoking, exercise, and obesity with bladder cancer mortality. We used mortality-linked data from the National Health Information Survey from 1998 through 2006. The primary outcome was bladder cancer-specific mortality. The primary exposures were self-reported smoking status (never- vs. former vs. current smoker), self-reported exercise (dichotomized as "did no exercise" vs. "light, moderate, or vigorous exercise in ≥ 10-minute bouts"), and body mass index. We utilized multivariable adjusted Cox proportional hazards regression models, with delayed entry to account for age at survey interview. Complete data were available on 222,163 participants, of whom 96,715 (44%) were men and 146,014 (66%) were non-Hispanic whites, and among whom we identified 83 bladder cancer-specific deaths. In multivariate analyses, individuals who reported any exercise were 47% less likely (adjusted hazard ratio [HR adj ], 0.53; 95% confidence interval [CI], 0.29-0.96; P = .038) to die of bladder cancer than "no exercise". Compared with never-smokers, current (HR adj , 4.24; 95% CI, 1.89-9.65; P = .001) and former (HR adj , 2.95; 95% CI, 1.50-5.79; P = .002) smokers were 4 and 3 times more likely, respectively, to die of bladder cancer. There were no significant associations of body mass index with bladder cancer mortality. Exercise decreases and current smoking increases the risk of bladder cancer-specific mortality. These data suggest that exercise and smoking cessation interventions may reduce bladder cancer death. Published by Elsevier Inc.

Genetic instability in urinary bladder cancer: An evolving hallmark.

Bladder cancer is a major health-care concern. A successful treatment of bladder cancer depends on its early diagnosis at the initial stage. Genetic instability is an essential early step toward the development of bladder cancer. This instability is found more often at the chromosomal level than at the nucleotide level. Microsatellite and chromosomal instability markers can be used as a prognostic marker for screening bladder cancer. Bladder cancer can be distinguished in two different categories according to genetic instability: Cancers with chromosomal level instability and cancers with nucleotide level instability. Deoxyribonucleic acid (DNA) mismatch repair (MMR) system and its correlation with other biologic pathway, both are essential to understand the basic mechanisms of cancer development. Microsatellite instability occurs due to defects in DNA MMR genes, including human mutL homolog 1 and human mutL homolog 2. Chromosomal alterations including deletions on chromosome 3, 8, 9, 11, 13, 17 have been detected in bladder cancer. In the current review, the most recent literature of genetic instability in urinary bladder cancer has been summarized.

Bioreactors are pivotal tools for generating mechanical stimulation in functional tissue engineering study. This study aimed to create a bioreactor that can simulate urinary bladder mechanical properties, and to investigate the effects of a mechanically stimulated culture on urothelial cells and bladder smooth muscle cells. We designed a bioreactor to simulate the mechanical properties of bladder. A pressure-record system was used to evaluate the mechanical properties of the bioreactor by measuring the pressure in culture chambers. To test the biocompatibility of the bioreactor, viabilities of urothelial cells and smooth muscle cells cultured in the bioreactor under static and mechanically changed conditions were measured after 7-day culture. To evaluate the effect of mechanical stimulations on the vital cells, urethral cells and smooth muscle cells were cultured in the simulated mechanical conditions. After that, the viability and the distribution pattern of the cells were observed and compared with cells cultured in non-mechanical stimulated condition. The bioreactor system successfully generated waveforms similar to the intended programmed model while maintaining a cell-seeded elastic membrane between the chambers. There were no differences between viabilities of urothelial cells ((91.90 ± 1.22)% vs. (93.14 ± 1.78)%, P > 0.05) and bladder smooth muscle cells ((93.41 ± 1.49)% vs. (92.61 ± 1.34)%, P > 0.05). The viability of cells and tissue structure observation after cultured in simulated condition showed that mechanical stimulation was the only factor affected cells in the bioreactor and improved the arrangement of cells on silastic membrane. This bioreactor can effectively simulate the physiological and mechanical properties of the bladder. Mechanical stimulation is the only factor that affected the viability of cells cultured in the bioreactor. The bioreactor can change the growth behavior of urothelial cells and bladder smooth muscle cells, resulting in

Radical cystectomy is the most effective treatment madality for high grade urinary bladder carcinoma and orthotopic reconstruction is the better urinary diversion modality also in women. From 2002 to 2007 we performed 14 radical cystectomies followed by orthotopic reconstruction in women aged between 47 and 68 years (mean age 56) affected by urinary bladder carcinoma. Our reconstructive technique requires the preparation of two strips of the recti muscles fascia, the sectioning of the bladder neck and, when the uterus is present, hysteroannessiectomy and cystectomy en block leaving intact the lateral and inferior vaginal walls. The pelvic floor is stabilized by a colposacropexis with a prosthesis and placing an omental flap over the prosthesis. The orthotopic reconstruction is achieved via a neobladder according to the Padovana technique. The ureters are anastomized to the neobladder and splinted with single J stents. The pathological examination demonstrated in all patients the presence of a high grade carcinoma (G3): more specifically 4 patients had a full thickness intramural infiltration (T2), 2 patients had involvment of the perivescical fat (T3) ad 8 patients were in T1 stage. Lymphnodes were negative for tumour (NO). In 8 patients blood transfusions were necessary to treat post surgical anemia. No significant intra-, peri- or post operative complications were noted. The mean follow-up was 45 months: a patient died for diffuse metastatic disease after 11 months. The remaining patients are still alive and report normal lifestyle: 10 with normal micturition and 4 with urinary retention treated with intermittent self-catetherization. Two patients report nocturnal incontinence treated with hourly micturition and one pad. The five patients who had normal preoperative sexual intercourse resumed a normal sexual activity. The possibility to orthotopically recontruct the female urinary bladder has been established long time after the introduction of orthotopic

We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

Leiomyoma of the bladder is a rare tumor arising from the submucosa. Most patients with bladder leiomyoma may present with urinary frequency or obstructive urinary symptoms. However, there are a few cases of bladder leiomyoma coexisting with uterine leiomyoma presenting as dyspareunia. We herein report an unusual case of coexisting bladder leiomyoma and uterine leiomyoma presenting as dyspareunia. A 44-year-old Asian female presented to urologist and complained that she had experienced dyspareunia over the preceding several months. A pelvic ultrasonography revealed a mass lesion located in the trigone of urinary bladder. The mass lesion was confirmed on contrast-enhanced computed tomography (CT). The CT scan also revealed a lobulated and enlarged uterus consistent with uterine leiomyoma. Then, the biopsies were then taken with a transurethral resection (TUR) loop and these biopsies showed a benign proliferation of smooth muscle in a connective tissue stroma suggestive of bladder leiomyoma. An open local excision of bladder leiomyoma and hysteromyomectomy were performed successfully. Histological examination confirmed bladder leiomyoma coexisting with uterine leiomyoma. This case highlights a rare presentation of bladder leiomyoma, dyspareunia, as the chief symptom in a patient who had coexisting uterine leiomyoma. Bladder leiomyomas coexisting with uterine leiomyomas are rare and can present with a wide spectrum of complaints including without symptoms, irritative symptoms, obstructive symptoms, or even dyspareunia.

It has been estimated that bladder and kidney cancers would be diagnosed in approximately 140,000 Americans in 2013, with approximately 30,000 dying from these cancers. Urinary tract cancers affect men more commonly than they do women, and the median age at diagnosis is 65 years. Major risk factors for these cancers include tobacco smoking, certain chemical exposures, family history, age, and obesity. Unexplained hematuria in adults should be evaluated to exclude bladder and kidney cancer. Staging of bladder and kidney cancer should be based on the TNM staging system, which, along with tumor grade, provides important treatment and prognostic information. Urothelial cell carcinoma is the most common type of bladder cancer; it also can occur in the kidneys or ureters. Renal cell carcinoma is the most common type of kidney cancer. Treatment options for bladder cancer vary widely, depending on the grade of the cancer. Early non-muscle-invasive bladder cancer may be removed cystoscopically and/or treated with intravesical immunotherapy or chemotherapy, whereas patients with muscle-invasive bladder tumors typically require surgery. Management of kidney cancer is almost always surgical, unless the patient is too ill to undergo surgery or chooses palliative care.

Unlike epithelial tumors, connective tissue tumors are uncommon, representing only 3 % of all bladder tumors. Leiomyoma of the bladder is the most frequent non-epithelial benign tumor of the bladder. Magnetic resonance imaging (MIR) is highly useful for diagnostic purposes and to determine the degree of extension. Only few reports of sonographic findings have been reported for leiomyoma of the bladder. The tumor usually develops within the bladder. Extra-vesicular formations have also been reported as well as a few intramural localizations. The characteristic feature is the absence of mucosal involvement. We analyzed the MRI findings in a case of leiomyoma of the bladder with intra and extra-vesicular development inflammatory reaction of the bladder wall and uterine adherences in a woman with a past history of chronic cystitis. The role of diagnostic MRI is discussed. (author)

Our aim was to assess the overall burden of congenital syndromes and non-cardiac comorbidities among adults with congenital heart disease and to assess their impact on circumstances of living and outcomes. Within a cohort of 1725 adults with congenital heart defects (65% defects of moderate or great complexity) followed at a single tertiary care center, congenital syndromes and comorbidities were identified by chart review. Their association with arrhythmias, circumstances of living and survival was analyzed. Within the study cohort, 232 patients (13%) had a genetic syndrome, 51% at least one comorbidity and 23% ≥2 comorbidities. Most prevalent comorbidities were systemic arterial hypertension (11%), thyroid dysfunction (9%), psychiatric disorders (9%), neurologic disorders (7%), chronic lung disease (7%), and previous stroke (6%). In contrast to higher congenital heart defect complexity, the presence of comorbidities had no impact on living circumstances but patients with comorbidities were less likely to work full-time. Atrial arrhythmias were more common among patients with moderate/great disease complexity and those with comorbidities but were less common among patients with congenital syndromes (pCongenital syndromes and comorbidities are highly prevalent in adults with congenital heart disease followed at specialist centers and add to the overall complexity of care. The presence of these additional factors has an impact on living circumstances, is associated with arrhythmias and needs to be further explored as prognostic markers. Copyright © 2017 Elsevier B.V.

Prateek Kinra

2017-01-01

Full Text Available Primary signet cell cancer of the urinary bladder is a relatively rare entity. Since there is no mucinous epithelium in the bladder, It is proposed that the tumor arises from metaplastic urothelium. Two thirds of the tumours are mucin secreting, in most of which the site of the deposition is either extracellular or intracellular displacing the nucleus to a peripheral crescent, giving the cells a signet ring appearance. The tumours are most often infiltrative and diffusely involving the majority of the bladder akin to its name sake in stomach. It is essential to distinguish this carcinoma from gastrointestinal metastases as different therapeutic strategies are often necessary.

Full Text Available Background: CMV is the most common agent that causes congenital virus infection. Only 10 % of infected children have symptomatic infection immediately after birth. Signs of central nervous system damage, neurosensory deafness and delayed psychomotor development may manifest as a result of asimptomatic congenital infection later in childhood. In the article we present basic properties of CMV; we describe clinical picture of the congenital infection and possibilities of diagnose and its treatment. We present five children with symptomatic congenital CMV infection that were hospitalized for the period 1992–2002 at the Neonatal department in the University Children’s Hospital in Ljubljana.Conclusions: Identification of infected neonates, especially those with asimptomatic congenital CMV infection, is difficult. Latest incidence of infection in Slovenia is unknown. With new investigations the efficiency of antiviral therapy was discovered but exact indications for therapy are not yet known. CMV vaccine, once available, may ultimately be the best control strategy for this important public health problem. Proper educating women in childbearing age about the risks of CMV and how to avoid disease transmission during pregnancy (hand washing, avoiding mouth-to-mouth contact with preschool children, usage of gloves especially when handling dipers or respiratory secretions are the only control strategies available.

We encountered a rare patient with Hunter's syndrome who exhibited urinary retention as a result of a neurogenic bladder, uninhibited detrusor contractions, and detrusor-sphincter dyssynergia. Neurological findings were consistent with cervical myelopathy and cervical MR imaging showed very narrow segments at the cord level C2-4. We speculate that this Hunter's syndrome patient has cervical myelopathy and that this neurological dysfunction causes the neurogenic bladder. PMID:8014981

Prevalence of congenital amusia.

Congenital amusia (commonly known as tone deafness) is a lifelong musical disorder that affects 4% of the population according to a single estimate based on a single test from 1980. Here we present the first large-based measure of prevalence with a sample of 20 000 participants, which does not rely on self-referral. On the basis of three objective tests and a questionnaire, we show that (a) the prevalence of congenital amusia is only 1.5%, with slightly more females than males, unlike other developmental disorders where males often predominate; (b) self-disclosure is a reliable index of congenital amusia, which suggests that congenital amusia is hereditary, with 46% first-degree relatives similarly affected; (c) the deficit is not attenuated by musical training and (d) it emerges in relative isolation from other cognitive disorder, except for spatial orientation problems. Hence, we suggest that congenital amusia is likely to result from genetic variations that affect musical abilities specifically.

2013-03-01

We explored the potential of an emerging laser-based technology, photoacoustic imaging (PAI), for bladder cancer diagnosis through high resolution imaging of microvasculature in the interior bladder tissues. Images of ex vivo canine bladders demonstrated the excellent ability of PAI to map three-dimensional microvasculature in optically scattering bladder tissues. By comparing the results from human bladder specimens affected by cancer to those from the normal control, the feasibility of PAI in differentiating malignant from benign bladder tissues was explored. The reported distinctive morphometric characteristics of tumor microvasculature can be seen in the images from cancer samples, suggesting that PAI may allow in vivo assessment of neoangiogenesis that is closely associated with bladder cancer generation and progression. By presenting subsurface morphological and physiological information in bladder tissues, PAI, when performed in a similar way to that in conventional endoscopy, provides an opportunity for improved diagnosis, staging and treatment guidance of bladder cancer.

Cisplatin-based chemotherapy has been widely used in a neoadjuvant as well as adjuvant setting. Furthermore, trimodal approaches including complete transurethral resection of the bladder tumor followed by combined chemotherapy and radiation have generally been performed as bladder preservation therapy. However, none of the protocols have achieved a 5-year survival rate of more than 70%. Additionally, the toxicity of chemotherapy and/or a decreased quality of life due to urinary diversion cannot be ignored, as most patients with bladder cancer are elderly. We therefore newly developed the novel trimodal approach of ''combined therapy using balloon-occluded arterial infusion of anticancer agent and hemodialysis with concurrent radiation, which delivers an extremely high concentration of anticancer agent to the site of a tumor without systemic adverse effects (''Osaka Medical College regimen'' referred to as the OMC regimen). We initially applied the OMC regimen as neoadjuvant chemotherapy for locally advanced bladder cancer. However, since more than 85% of patients with histologically-proven urothelial cancer achieved complete response with no evidence of recurrence after a mean follow-up of 170 (range 21-814) weeks, we have been applying the OMC-regimen as a new approach for bladder sparing therapy. We summarize the advantage and/or disadvantage of chemotherapy in neoadjuvant as well as adjuvant settings, and show the details of our newly developed bladder sparing approach OMC regimen in this review.

Low energy shock wave (LESW) is known to facilitate tissue regeneration with analgesic and anti-inflammatory effects. We examined the effects of LESW on the expression of inflammatory molecules, pain behavior, and bladder function in a rat cystitis model. Control and experimental animals were injected with saline or cyclophosphamide (CYP; 75 mg/kg intraperitoneally) on day 1 and 4. After lower midline incision, the bladders were exposed to LESW (300 pulses, 0.12 mJ/mm 2 ) or sham operation on day 2. In study 1 (N = 12, 4 for each group), the nociceptive effects of CYP were evaluated for 30 min by behavioral assessment on day 4 one hour after CYP injection. In study 2 (N = 21, 7 for each group), continuous cystometry (CMG) was performed on day 8. The bladder was harvested after behavioral assessment or CMG for histology and Western blotting. CYP-induced upregulation of COX2 and IL6 expression, caused pain behavior (eye closing and hypolocomotion), and bladder inflammation was noted on days 4 and 8 along with bladder hyperactivity. LESW treatment reduced pain behavior and downregulated the NGF expression (33.3%, P < 0.05) on day 4 and IL6 (40.9%, P < 0.05). LESW treatment suppressed bladder overactivity (intercontraction interval 77.8% increase, P < 0.05) by decreasing inflammation and COX2 (38.6%, P < 0.05) expression and NGF expression (25.2%, P = 0.0812). CYP-induced bladder pain, inflammation, and overactivity involves activation of IL6, NGF, and COX2 expression. These changes are suppressed by LESW, indicating it as a potential candidate for relieving bladder inflammatory conditions and overactivity. © 2016 Wiley Periodicals, Inc.

The objective of this study was to assess health-related quality of life (QOL) of bladder cancer patients following bladder preservation therapy (BPT). Eighty patients with muscle-invasive bladder cancer had been treated between January 1992 and July 2005 at our institutions with BPT consisting of transurethral resection, intra-arterial chemotherapy and radiotherapy. Among them, 48 were alive and free from recurrence at the time of survey and were asked to participate. A total of 168 patients who had been treated for superficial bladder cancer in the same period were used as a control group. Three questionnaires, namely the International Prostate Symptom Score (IPSS), the SF-36, and the Expanded Prostate Cancer Index Composite (EPIC) were used. Thirty-three patients in the BPT group (68.8%) and 128 patients in the control group (76.2%) answered the QOL survey. There was no significant difference in age, gender and other clinical factors among these two groups. No significant difference was found between the groups according to IPSS. The QOL score of BPT was lower than that of the control group in the SF-36, but there was no significant difference without body pain (P=0.047). There was a tendency toward a diminished physical functioning (P=0.053) and role-physical (P=0.064) in BPT. The EPIC scores for urinary function, especially storage and voiding symptoms, and bowel function were significantly lower in the BPT group. At multivariable analysis, body pain and bowel function were associated with the type of treatment. Although some of the QOL outcome parameters after BPT were found to be lower than the control group, these differences were not significant. Overall, patients retaining their bladder had an acceptable health related QOL. (author)

The emerging role of the androgen receptor in bladder cancer.

Men are three to four times more likely to get bladder cancer than women. The gender disparity characterizing bladder cancer diagnoses has been investigated. One hypothesis is that androgen receptor (AR) signaling is involved in the etiology and progression of this disease. Although bladder cancer is not typically described as an endocrine-related malignancy, it has become increasingly clear that AR signaling plays a role in bladder tumors. This review summarizes current findings regarding the role of the AR in bladder cancer. We discuss work demonstrating AR expression in bladder cancer and its role in promoting formation and progression of tumors. Additionally, we discuss the therapeutic potential of targeting the AR in this disease. © 2015 Society for Endocrinology.
