Spectrum of Multicystic Dysplastic Kidney / 대한비뇨기과학회지

ABSTRACT

Multicystic dysplastic kidney is the most frequent cause of abdominal mass in the neonate, but its presentation is variable depending on the size of cystic kidney, state of the opposite kidney and associated anomalies. multicystic dysplastic kidney also represents a spectrum of pathology from unilateral multicystic kidney through segmental and focal multicystic dysplasia to bilateral multicystic kidney. Herein we report 5 cases of MCK with different presentation and histology, a bilateral MCK associated with horseshoe kidney, a large MCK with uremia, a focal segmental MCK with contralateral UPJ obstruction, a small focal segmental MCK with contralateral megaureter and a small MCK detected by ultrasonogram for localization of impalpable testis.
