[An old complication returns. Anuria caused by ureteral catheterization].

A case of secondary anuria following the insertion of a double pigtail stent to treat an anuria due to a tumoral obstruction of the ureter is presented. Washing of the stent through a second ureteral catheter parallel to it proved the patency of the stent. Diuresis ensued at last by the administration of diuretics and leaving both the stent and the ureteral catheter in place. The literature is reviewed and discussed.
