[Horseshoe kidney in an infant associated with ureteropelvic junction and ureterovesical junction obstructions].
A 4-month old baby was seen in August, 1982 because of abdominal distension. The findings of the physical examination were normal except for a man's fist sized mass in the left upper abdomen. IVP revealed left nonvisualizing kidney. CT scans revealed a large mass in the left abdomen with low density contents and renal scintigraphy revealed a horseshoe kidney. The tentative diagnosis was horseshoe kidney associated with hydronephrosis due to ureteropelvic junction obstruction. Left pyeloplasty was performed in September 1982 and postoperative X-ray examinations revealed left ureterovesical junction obstruction. Left ureteroneocystostomy was performed in October, 1982 and postoperative course was uneventful. Horseshoe kidney in infants is rare in the Japanese literature and our case is quite unique in that horseshoe kidney is associated with ureteropelvic junction and ureterovesical junction obstruction.
