1/124. Endovascular stent graft for management of ureteroarterial fistula after orthotopic bladder substitution.We describe the first case of an ureteroarterial fistula developing after orthotopic neobladder substitution and its minimally invasive management using endovascular stent grafting. We outline the risk factors for the development of ureteroarterial fistulae and trace the evolution of diagnostic and therapeutic modalities used in the management of these life-threatening complications. Minimally invasive management with endovascular stent grafting and exclusion of two pseudoaneurysms in the iliac artery system was performed successfully. After successful endovascular exclusion of two pseudoaneurysms, the patient's hematuria resolved and he recovered fully. Three-dimensional computed tomography performed 3 months later documented a patent aortoiliac arterial system without evidence of pseudoaneurysm or endovascular leak. Ureteroarterial fistula after orthotopic bladder substitution was managed with an endovascular stent graft without the need for extra-anatomical vascular bypass. Early recognition, stabilization, and angiographic evaluation followed by this minimally invasive technique may avoid open operative repair and attendant morbidity.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
2/124. Endovascular management of ureteroarterial fistula.Ureteroarterial fistulas, although rare, appear to be increasing in frequency. Because open surgical repair may be difficult and associated with significant risk for complications, endovascular intervention may provide an attractive treatment alternative. We review the diagnosis and management of a ureteroarterial fistula and iliac pseudoaneurysm that presented with massive hematuria during ureteral stent removal. The patient was treated by means of the percutaneous embolization of the right hypogastric artery and placement of an expanded polytetrafluoroethylene stent-graft. Endovascular stent-graft placement may serve as a safe and practical alternative in the treatment of these patients, whose cases are challenging.- - - - - - - - - - ranking = 0.85714285714286keywords = fistula (Clic here for more details about this article) |
3/124. Ureterorectal fistula: a rare cause of recurrent bacteriuria.The differential diagnosis of recurrent bacteriuria includes a host of conditions very familiar to urologists. Ureterorectal fistula represents an unusual clinical entity that can cause recurrent bacteriuria. We present a patient who ultimately proved to have such a fistula. We review the available literature and comment on the significance of this condition.- - - - - - - - - - ranking = 0.85714285714286keywords = fistula (Clic here for more details about this article) |
4/124. Rare case of left-sided ureteroduodenal fistula.BACKGROUND/AIMS: Ureteroduodenal fistulas are rare and only 11 cases have been reported in the literature since 1918. diagnosis requires careful observation of symptoms. methods: The case presented demonstrates a 68-year-old female with left-sided ureteroduodenal fistula confirmed by CT scan. A duodenal fistula was localized and an atrophic left kidney was identified and repaired. RESULTS: Nephroureterectomy was performed and an omental patch was used for the repair. No complications were encountered during the postoperative course. CONCLUSIONS: Recurrent chronic urinary tract infection, pyuria and hematuria can indicate this rare disease. Early testing and detection can improve the chances of renal preservation.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |

6/124. A ureterocutaneous fistula forty years after nephrectomy.The case of a woman presenting with a ureterocutaneous fistula 40 years after nephrectomy is described. Because of advanced respiratory disease and absence of infective activity, a conservative line of treatment with saline rinse was given. At 3 months follow-up the fistula had become chronic, with a small opening without signs of infection and ultrasound revealed no abscess.- - - - - - - - - - ranking = 0.85714285714286keywords = fistula (Clic here for more details about this article) |
7/124. Use of balloon catheters for ureteral occlusion in urinary leakage.PURPOSE: urinary fistula after treatment for cancer constitutes a therapeutic dilemma, especially in patients who have had various other treatments. We report on 7 patients with urinary leakage, treated conservatively with ureteric occlusion by way of percutaneous transrenal balloon catheters. MATERIALS AND methods: The indication for ureteral occlusion was persisting urinary leakage despite diversion by nephrostomy and drainage with atransurethral catheter. All patients had had previous treatment because of pelvic malignancy. Small Foley balloon catheters and angioplasty catheters were used. These devices were inserted percutaneously in an antegrade fashion. RESULTS: In all but 2 of the patients the leakage ceased with the aid of these devices. Insufficient ureteral occlusion necessitated unilateral uretero-cutaneostomy in 1 patient. In another patient a vesico vaginal fistula was closed surgically. The maximum duration of occlusion was 169 (mean 94, range 45-169) days, without any evidence of ureteric pressure necrosis. Despite good overall results many adjustments and replacements of catheters were necessary because of recurrent urinary leakage caused by inadequate obstruction and/or leakage of the occluding catheters. CONCLUSIONS: We conclude that long-term ureteral occlusion with percutaneous transrenal balloon catheters appears to be safe and does not result in pressure necrosis. Using this approach, urinary fistula can heal in some patients without the need for open surgery.- - - - - - - - - - ranking = 0.42857142857143keywords = fistula (Clic here for more details about this article) |
8/124. diagnosis and management of post-cesarean ureterouterine fistulae.Urinary leakage following obstetric or gynecologic surgery is a dreaded complication, most often caused by a urogenital fistula. Of these, uretero-uterine fistulae are relatively rare and pose a diagnostic and therapeutic dilemma. A 29-year-old woman presented with paradoxical incontinence of urine for 3 months. She had developed vaginal leakage of urine 2 weeks following an uneventful cesarean section. Conservative measures in the form of catheterization and bed rest did not relieve her symptoms. Subsequent examination and investigations revealed that she had a ureterouterine fistula. The case is discussed as well as the diagnostic modalities and treatment options.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |

Ureteroileal fistula: an unusual complication of Crohn's disease.We report a case of urteroileal fistula in a young 22 year-old-man with Crohn's disease, who presented with microscopic hematuria and severe diarrhea. Excretory urogram and retrograde pyelography showed a fistula between the right ureter and the terminal ileum which was successfully managed with conservative approach using a double J ureteral stent.- - - - - - - - - - ranking = 0.85714285714286keywords = fistula (Clic here for more details about this article) |
10/124. Ureteroarterial fistula in a patient with a single functioning kidney.A rare case is reported of a fistula between the left internal iliac artery and the left ureter in a patient whose left kidney was the only functioning kidney. Internal iliac artery embolization was initially successful in stopping the bleeding, but the fistula recurred when the ureteral stent was removed. Even after embolization, the tissue surrounding a fistula remains very fragile, so the fistula may easily recur as a result of slight injury or inflammation.- - - - - - - - - - ranking = 1.1428571428571keywords = fistula (Clic here for more details about this article) |
