Abstract

Supernumerary kidney is one of the rarest anomalies of the urinary system. We experienced a 62-year old male case in whom supernumerary kidney accompanied by vesico-ureteral reflux was highly suspected. Intravenous urography revealed completely duplicated ureters on the left side. On abdominal CT, a mass which was presumed to be a small and atrophic supernumerary kidney was depicted at the caudal and abdominal portion of the left major kidney. On cystography, vesico-ureteral reflux to the supernumerary kidney was observed and the pelvis of the supernumerary kidney showed hydronephrosis due to uretero-pelvic junction stenosis. Infection was controlled by oral administration of anti-bacterial drug. The patient remains under observation at our outpatient clinic. Extirpation of the supernumerary kidney will be carried out if infection becomes refractory to treatment.
