Ureteric Obstruction Due to Kinking of the Reservoir Inlet in a Continent Urinary Reservoir

We report a case of symptomatic intermittent upper tract obstruction in a continent urinary reservoir. The ureters were of great intraperitoneal length and were positioned in front of the mesenterium, resulting in a mobile reservoir. Only the retroperitoneal part of the ureters was dilated due to kinking in the peritoneal passage. After the ureters were shortened and reanastomosed retroperitoneally, the repeated episodes of abdominal pain and discomfort disappeared.
