We present 2 cases from our clinic with complications due to unilateral multicystic dysplastic kidneys: 1 case with arterial hypertension, another case with a renal carcinoma in a multicystic dysplastic kidney. Compared with the 62 cases already published, these are the 2nd case of hypertension and the 3rd case of carcinoma in multicystic dysplastic kidneys. Because of such complications nephrectomy of multicystic dysplastic kidneys is indicated.
