Renal autotransplantation for retroperitoneal fibrosis.

Idiopathic retroperitoneal fibrosis is a disease of unknown etiology characterized by a dense rubbery retroperitoneal plaque that encases 1 or both ureters, causing hydronephrosis and impairing renal function. Primary or recurrent disease may result in extensive ureteral damage, leaving the urologist with limited surgical options. We herein report the fourth case managed successfully by renal autotransplantation.
