title: [Bladder stone at an ureterovesical anastomotic site after renal transplantation: a report of three cases].
abstract: Three cases of bladder stones at the ureterovesical anastomotic site after renal transplantation (RT) are reported. The three patients were successfully treated with kidney grafts. The method used for the ureter bladder anastomosis in all patients was the extravesical technique with polyglyconate (Maxon) for case 1 and a polydioxanone suture (PDSII) for cases 2 and 3. Calculi formation was found between 3 to 15 months after RT. Endoscopic vesicolithotripsy was performed and the stones adherent to the ureterovesical anastomotic site were removed successfully in all cases. Stone analysis revealed uric acid (case 1), CaOx and CaP (case 2). Stone analysis was not done in case 3. The patients' symptoms improved and no bladder stones could be discerned postoperatively.
