Primary obstructed megaureter is a common urological condition in the pediatric age group. It is one of the differentials for congenital anomalies of the kidney and urinary tract that include a myriad of structural anomalies of the urinary tract. The obstructive conditions are usually managed conservatively unless there is deterioration in renal function, repeated urinary tract infection, or any other symptom such as abdominal pain on ipsilateral side and hypertension. Presented here is a case of left lower ureteral valve that was diagnosed as primary obstructed megaureter with pain in abdomen and reduced ipsilateral renal function wherein ureteral valve was detected incidentally intraoperatively. Excision of the valve with end to end uretero-ureteral anastomoses over a D-J stent, without resorting to ureteric reimplantation was successful in relieving the obstruction and hydronephrosis.
