The continence success rate with ureterosigmoidoscopy and its variants is higher than 95% for exstrophy; however, long-term malignancy rates are quite high. Adenocarcinoma is the most common of these malignancies, and may be caused by chronic irritation...
and inflammation of exposed mucosa of the exostrophic bladder. In one series of studies, adenocarcinoma was reported in more than 10% of patients. However, the malignancy is actually higher in untreated patients whose bladders are left exposed for years before surgery.
Upper urinary tract deterioration is a potential complication, caused by reflux of urine back to the kidneys, resulting in febrile infections.

Ureterosigmoidoscopy is a surgical procedure that treats urinary incontinence by joining the ureters to the lower colon, thereby allowing urine to evacuate through the rectum.
The surgical techniques for urinary and fecal diversion fall into two categories: continent diversion and conduit diversion. In continent diversion, an internal reservoir for urine or feces is created, allowing natural evacuation from the body. In urinary and fecal conduit diversion, a section of existing tissue is altered to serve as a passageway to an external reservoir or ostomy. Both continent and conduit diversions reproduce bladder or colon function that was impaired due to surgery, obstruction, or a neurogenically created condition. Both the continent and conduit diversion methods have been used for years, with advancements in minimally invasive surgical techniques and biochemical improvements in conduit materials and ostomy appliances.
