Introduction:
Endourological intervention is a minimally invasive approach for the management of ureteral strictures. Contraindications to this approach include active infection, strictures of sizes >2 cm, and failure of endoureterotomy. This report demonstrates a case of successful dual stent placement after redo endoureterotomy.
Case Presentation:
A recurring ureteral stricture in a 69-year-old woman, who had undergone ureteroscopic lithotripsy for a right ureteral calculus 60 months earlier, was successfully managed by redo endoureterotomy. The procedure involved insertion of dual ureteral stents after endoluminal incision and balloon dilation. Ureteral stents were removed 8 weeks after the operation. No significant complications or signs of stricture were observed 42 months after endoscopic repair.
Conclusion:
This minimally invasive and effective technique of dual ureteral stent placement following laser endoureterotomy successfully managed the recalcitrant ureteral stricture in a case with failed single stent placement following endoureterotomy.
