Multi Imaging Modality in Diagnosis of Unusual Giant Hydronephrosis of the Non Functioning Lower Moiety in A Partial Duplex Kidney with Distal Ureteric Stricture

Abstract

Duplex collecting system of the kidney is a common congenital anomaly of the urinary tract. It is usually asymptomatic clinically with normal renal function. In rare instances, it may complicate with giant hydronephrosis. The following is a case of a middle aged woman with history of recurrent urinary tract infections (UTI) and flank pain diagnosed with bilateral partial duplex kidney complicated with unusual non-functioning lower moiety left giant hydronephrosis due to distal left ureteric stenosis which probably enhanced the reverse flow of urine together with YO-YO reflux.
