title: [Bladder stone formation caused by a Stamey cuff as the nidus indwelt 16 years ago].
abstract: Although foreign bodies left in the body may remain asymptomatic for long periods, they may also cause various complications. We present a case of a Stamey cuff placed in the retroperitoneal space, which remained asymptomatic for 16 years in a 62-year-old woman. When a vesical calculi formed, it caused voiding pain in the lower abdomen. She underwent transurethral cystolitholapaxy. The nidus of the stone was a Stamey cuff used in the Stamey procedure performed 16 years before. Open cystotomy was needed to remove it. Convalescence was uneventful and she had no complaints on urination. The possibility of calculous formation should be raised when there are symptoms on urination in a female with a history of pelvic surgery.
