Percutaneous ureteral stent insertion

Percutaneous ureteral stent insertion is a treatment of permanent or temporary urinary diversion to maintaincontinuity and function of the obstructed and injured ureter. We performed 31 cases of percutaneous double pigtail ureteral stent insertion in 21 patients, included 13 patients with malignant ureteral obstruction and eightpatients with injured ureter as well as benign inflammatory stricture. Satisfactory result was obtained in allpateints but one, who need percutaneous nephrostomy one week later for urinary diversion. No significantcomplication was encountered. The authors conclude that percutaneous ureteral stent insertion, an interventionalprocedure alternative to urologic retrograde method, is an effective method for urinary diversion.
