Objective The main points of diagnosis and treatment of ureterocutaneous fistula after in situ bladder operation were discussed based on clinical data and literature.Methods This report presents the data of a patient who developed a ureterocutaneous fistula 10 years after an in situ bladder procedure at Yuechi County People's Hospital.Results A 77-year-old male underwent laparoscopic cystectomy with orthotopic ileal neobladder for bladder cancer.The case manifested as fluid leakage from the original surgical incision,initially misdiagnosed as abdominal wall sinus.After right nephrectomy due to non-functional kidney,the fistula healed.Conclusion Ureterocutaneous fistulas are commonly associated with kidney transplantation and postoperative complications of upper urinary tract such as calculi and xanthogranulomatous pyelonephritis.Fistulography can be conclusive for this condition.Prompt identification and repair of urinary tract injuries are crucial.
