First report of an unexpected blind-ending duplication of the ureter as a rare pitfall in kidney transplantation.
We report on the case of an unexpected blind-ending ureter in a kidney transplant. To our knowledge, this is the first report of a blind-ending ureter in kidney transplantation. The recipient was a 60-year-old woman, with a 6-year history of chronic haemodialysis. During the performance of ureterocystostomy, the ureteric stent could not be placed in the renal pelvis as the ureter, surprisingly, was found as blind-ending in the ureteral sheath. Dissecting the ureteral sheath a second shorter ureter was found and used for ureterocystostomy. The histology reported a normal ureter, which led to a thread of connective tissue. The patient had an uneventful recovery; the creatinine was 1.07 mg/dl at discharge from the hospital. It is mandatory for the transplanting surgeon to be aware of the ureteral variations and the surgeon should be trained in the surgical management of these variations. Accuracy should be ensured when exploring the exact anatomy of the donor organ.
