Malrotated Right Supernumerary Kidney: Case Report of A Rare Anomaly

Supernumerary Kidney is a one of the rarest congenital renal anomalies with less than 100 cases reported in the literature. This accessory kidney has its own collecting system, vascular supply and well-defined capsule. We report a case of 18-year-old lady with a history of vague intermittent abdominal pain and has palpable abdominal mass who was found to have malrotated right supernumerary kidney with pelviureteric junction obstruction.
