Pyeloureteral duplication is a duplication of the excretory system of a renal unit. Renal duplication is a congenital anomaly, estimated in the general population at 1/125. Familial forms have been described and estimated at 1 in 8 in the siblings. Upper urinary tract malformations are not uncommon in adults and can lead to destruction of the renal parenchyma if diagnosis and management are delayed. Recurrent back pain is the most common symptom. It may also be due to infectious complications of the upper pyelo in stasis or due to ectopy. Urinary lithiasis is found in 26% of cases according to some series. Endoscopic incision in the context of ureteral duplicity, completed by ureteroscopy with drainage of the Upper excretory tract, may be the treatment of choice in adults. Simple, minimally invasive and with low morbidity, it allows an efficient drainage.
