SUCCESSFUL ENDOSCOPIC TREATMENT OF STRICTURE OF URETEROENTERIC ANASTOMOSIS BY IMPLANTATION OF BILIARY FULLY COVERED METAL STENT

A 67-year-old male underwent renal transplantation with an ileal conduit urinary diversion due to bladder dysfunction. In early post-transplant period, he developed a stricture of the ureteroenteroanastomosis. The anastomosis was reached via ileostomy using a side-viewing scope and two biliary double-pigtail plastic stents were placed. Three months later, the plastic stents were exchanged for a biliary fully covered metal stent (WallFlex 60x6mm, Boston Scientific). To prevent migration, the proximal (enteric) side of the metal stent was secured by a plastic biliary double pigtail stent positioned transversally through the mesh. After six months, resolution of the stricture allowed for stent removal.
