Double pigtail ureteral stent.
Abstract
Problems encountered in patients with ureteral obstruction treated with single pigtail polyethylene ureteral catheters (stents) were largely due to positioning difficulties, proximal migration, and irritation of the bladder mucosa by the distal flange. A new, double pigtail modification of this self-retained internal stent limits migration, minimizes irritant side effects, and facilitates endoscopic, percutaneous, and open surgical positioning over a springwire guide. These stents provide useful alternative to surgical correction or external tube diversion in many patients with complicated ureteral obstruction.
