Abstract
Ureteral obstruction due to idiopathic retroperitoneal fibrosis is a rare but severe clinical problem. The open approaches, as well as surgical techniques used to prevent stenosis recurrence, are described. Ureterolysis remains the procedure to relieve ureteral obstruction. The ureter is dissected and freed from the fibrotic process, and then separated to prevent the recurrence of the stenosis. Recently, the development of laparoscopic urology has allowed for minimal invasive treatment of many urological problems. We present our technique of ureterolysis for extrinsic ureteral obstruction. Advantages and complications of each method are considered and indications are proposed.
