Multicystic kidney dysplasia and Turner syndrome: two cases and a literature review

Renal malformations occur in 33%–70% of cases of Turner syndrome (chromosome 45 and variants). We describe two cases of multicystic dysplastic kidney in Turner syndrome. A literature review of renal abnormalities in Turner syndrome shows the frequency of cystic disease to be 1.76%. In multicystic dysplastic kidney, diagnostic investigation of the contralateral kidney, including voiding cystourethrography, is necessary in view of the high incidence of associated diseases (15%–20% of cases, vesicoureteric reflux) and other anomalies.
