Unilateral multicystic dysplastic kidney disease associated with ipsilateral ureteric bud remnant and contralateral duplex collecting system

Abstract

Congenital anomalies of the kidney and urinary tract are among the most common developmental malformations. The heterogeneity of these anomalies is very high, some of them are rarely discussed in the literature. Herein, we present a case of a 5-year-old male who was found to have a combination of unilateral multicystic dysplastic kidney associated with ipsilateral ureteric bud remnant and contralateral duplex collecting system.
