Breakage of a silicone double pigtail ureteral stent as a long-term complication.

A variety of indications have made the use of double pigtail ureteral catheters routine in urological practice. Although side effects are frequent they are usually mild. Complications with long-term indwelling stents are mainly due to stent incrustation or stone formation. We report a case of stent breakage without incrustation after an indwelling period of 29 months. To our knowledge such a severe complication of a silicone double pigtail stent has not been described previously. This complication also signifies that the period a stent is left indwelling is critical and should be monitored carefully.
