Unilateral Multicystic Dysplastic Kidney With Progressive Infundibular Stenosis in the Contralateral Kidney: Experience at 1 Center and Review of Literature

Abstract: Our cases represent a part of the spectrum of pyelocalyceal dysgenesis that can have bilateral involvement of varying degrees. Of particular concern was the delayed presentation in some of our patients and the progressive nature of the lesions. Although exceedingly rare, we wish to highlight the association of multicystic dysplastic kidney and progressive infundibular stenosis of the contralateral kidney and renal impairment.

“…Infundibulopelvic dysgenesis is a rare condition characterized by congenital malformation of the pelvicalyceal system. The spectrum of gongenital disorders includes focal and multifocal abnormalities leading to multicystic dysplastic kidney (MCDK), infundibulopelvic stenosis, calyceal diverticula, and ureteropelvic junction obstruction [8,9]. The theory assumes that infundibulopelvic dysgenesis is the result of early or late budding of the ureter during embryogenesis [10].…”

“…When these patients underwent nephrectomy for progressive hydronephrosis, surgical pathology showed hyperfiltration injury. An additional study by Dally et al described two hundred children with MCDK, five of whom had infundibular stenosis in the contralateral kidney [ 2 ]. Of these, four presented as neonates with stenosis seen by ultrasound or noted as an asymptomatic palpable mass.…”

“…This spectrum includes focal and multifocal abnormalities leading to multicystic dysplastic kidney (MCDK), infundibulopelvic stenosis, calyceal diverticula, and ureteropelvic junction obstruction [ 1 ]. Infundibular stenosis has been associated with MCDK; in one series 2.5% of children with MCDK have some degree of stenosis in the contralateral kidney [ 2 ].…”
