Renal anomalies in fetal alcohol syndrome.

Six patients with fetal alcohol syndrome were found to have developmental abnormalities of the kidney. In only one patient was investigation for renal pathology made in the absence of clinical indication. Two had palpable masses in the left upper quadrant, one had pyelonephritis, one had painless hematuria, and the fifth patient had symptomatology suggestive of renal failure. Although the renal pathology was not of the same type in all cases, it is of interest that four patients had either unilateral or bilateral renal hypoplasia.
