Endourological treatment of nonmalignant upper urinary tract complications after urinary diversion.
Endourological modalities are considered the first line of treatment for benign ureterointestinal anastomotic strictures except in long strictures, completely obliterated lumen, prior radiation, and poor renal function. Endoureterotomy provided better success than balloon dilatation. In poor-operative risk patients, metal or double-J stents are viable options. Endourological treatments of upper tract stones after diversion are indicated for stones not suitable for shock wave lithotripsy (SWL) or to salvage SWL failure. Percutaneous nephrolithotomy was preferred for large or complex renal stones, whereas ureteroscopy was used for smaller stones. The evaluation of stone-free status and regular follow-up are mandatory because of the high recurrence rate.
