title: Long-term indwelling bilateral ureteral stents for bilateral hydronephrosis of unknown etiology.
abstract: We describe a rare case of long-term indwelling bilateral ureteral stents that were replaced yearly for 7 years because of azotemia associated with bilateral hydronephrosis of undetermined etiology on radiological examinations. During year 5 the patient had an uneventful gestation with delivery of a normal neonate by cesarean section. Hydronephrosis remained improved for 2 years after withdrawal of the stents.
