Case report reveals hydronephrosis due to ureteral stone in duplex kidneys, indicating surgical intervention.
Duplex kidneys, though relatively uncommon (occurring in 1%–4% of the cases), can pose significant clinical challenges when associated with urinary tract symptoms. Complications requiring intervention include stone formation, urinary obstruction, and reflux disease. We present the case of a 22‐year‐old male with complete duplex right kidney with upper moiety hydronephrosis due to a distal ureteral stone, diagnosed by ultrasonography and confirmed with intraoperative retrograde pyelography (RPG). Definitive management was achieved via ureteroscopy (URS) lithotripsy.
