Clinical case of hydronephrotic form of multicystic dysplastic kidney complicated by pyelonephritis in adults

Abstract

Multicystic dysplastic kidney (MCDK) is a renal dysplasia characterized by the presence of multiple cysts that are non-communicating, varying in size, separated by dysplastic parenchyma that consume the renal cortex resulting in a non-functional kidney with the absence of a normal pelvocaliceal system. The incidence of MCDK is approximately 1 : 4300 of live births, with males being affected more often than females. Many concurrent urinary tract abnormalities have been described in patients with MCDK. The most common and potentially significant urologic defect seen is vesico-ureteral reflux to the contralateral kidney. In our clinical case, multicystic dysplastic kidney complicated by hydronephrotic transformation and septic obstructive pyelonephritis, which deve­loped on the base of undiagnosed vasorenal conflict.
