1/224. Bilateral ureteritis cystica with unilateral ureteropelvic junction obstruction.Ureteritis cystica is a rare, benign, proliferative disorder characterized by multiple ureteral cysts and multiple filling defects noted on contrast ureteral imaging. A unique case of bilateral ureteritis cystica coincidental with chronic, congenital, unilateral ureteropelvic junction obstruction presenting with microscopic hematuria and lower urinary tract symptoms is described. The characteristic presentation as well as the diagnostic radiographic, ureteroscopic, and histologic features of pyeloureteritis cystica are reviewed.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
2/224. 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 = 19.858793039962keywords = fistula (Clic here for more details about this article) |
3/224. 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 = 17.021822605682keywords = fistula (Clic here for more details about this article) |
4/224. Pyelo-ureteritis cystica associated with a urinary tract infection due to a coagulase-negative staphylococcus.A young female presenting with a history suggestive of renal colic was found by intravenous pyelography to have Pyeloureteritis Cystica. In association with this condition she had a urinary tract infection due to a coagulase-negative staphylococcus. Following a two week course of appropriate antibiotic therapy, her urine became sterile and repeat pyelography revealed no abnormality.- - - - - - - - - - ranking = 5keywords = urinary (Clic here for more details about this article) |
5/224. Hemorrhagic pyelitis, ureteritis, and cystitis secondary to cyclophosphamide: case report and review of the literature.OBJECTIVE: Hemorrhagic cystitis is a well-known complication of cyclophosphamide therapy but extensive involvement of the entire urinary tract is far less common. We report here a patient who developed severe hemorrhagic pyelitis, ureteritis, and cystitis after one cycle of cyclophosphamide-containing combination chemotherapy. METHOD: A patient with synchronous carcinoma of the ovary and the uterus developed severe hemorrhagic pyelitis, ureteritis, and cystitis leading to bilateral hydronephroses and acute renal failure after one cycle of combination chemotherapy containing cyclophosphamide. The blood clots in the upper urinary tract were aspirated endoscopically and bilateral internal ureteric stents were inserted. RESULT: She underwent a prolonged diuretic phase with several episodes of hypokalemia, hypomagnesemia, and hypocalcemia and required intensive fluid and electrolytes replacement. Subsequently, she recovered fully with the ureteric stents removed 26 days later. CONCLUSION: In contrast to previous reports, where 2.8 g of cyclophosphamide was estimated to be the minimum cumulative dose required to cause hemorrhagic cystitis, this case illustrates that severe hemorrhagic complication can occur even after a low dose of cyclophosphamide (600 mg/m(2), total dose of 846 mg). Prompt diagnosis and intervention may be life-saving.- - - - - - - - - - ranking = 2keywords = urinary (Clic here for more details about this article) |
6/224. cytomegalovirus infection may cause ureteral necrosis.cytomegalovirus (CMV) infection has protean presentation among immunocompromised patients, but the urinary tract is rarely involved. We report a case of extensive ureteral necrosis in a renal transplant, 12-year-old patient with typical histological feature of CMV inclusions. The role of CMV was confirmed by immunohistochemical analysis and concomitant CMV dna detection in peripheral blood leukocytes by polymerase chain reaction analysis. CMV infection can, therefore, be regarded as a possible cause of ureteral necrosis in renal transplant recipients.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
7/224. 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 = 17.021822605682keywords = fistula (Clic here for more details about this article) |
8/224. Endoscopic management of prolapsing intravesical ureterocele in an adult female--a case report.The authors present a case of intravesical ureterocele in a female which prolapsed out of the external urethral meatus causing urinary obstruction, and was managed by reduction into the bladder followed by endoincision.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
9/224. Ureter diverticulum of transplanted kidney. Case report.OBJECTIVES: Authors present a case of successful surgical treatment of a ureter diverticulum observed 3 months after kidney transplantation. methods: The fluid collection was detected by ultrasound. Percutaneous drainage was performed, after that the excretion of 4 litres of fluid was observed during 12 hours. This finding clearly indicated the connection with the urinary system. This fact was proved and precisely localised by contrast filling of the lesion under fluoroscopic control. RESULTS: Resection of the ureter diverticulum was performed, and the patient recovered fully, there was no change observed in the graft function during the whole procedure. CONCLUSION: The ureter diverticulum is a rare complication after kidney transplantation: the present case is the only one observed among more then 600 kidney transplantations performed during 20 years in our centre.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
10/224. 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 = 20.858793039962keywords = fistula, urinary (Clic here for more details about this article) |
