Congenital hydronephrosis, although well known, is not a common condition. In the literature one finds a moderate number of reports of so-called congenital hydronephrosis, many of which lack substantial evidence of proof of the clinical diagnosis by autopsy.

REPORT OF A CASE
History.—A girl, S., weighing 7 pounds (3,175.1 Gm.), was delivered by breach extraction on June 20, 1933.

The lower border of the liver was 2 fingerbreadths below the right costal margin. Immediately below this organ the upper border of a swelling could be outlined. This mass was the size of a lemon
