Giant Hydronephrosis Caused by Trauma: A Case Report

Lee, Yoon Hyung

Abstract

A giant hydronephrosis containing 7,100 cc of fluid with a proved traumatic origin in a 21 year old man is presented. The patient got a forceful kick in the upper right abdomen, 6 months previously. Subsequently, there were episodes of hematuria for ten days. The second blow was added in the same region on the day before operation and progressive abdominal swelling was observed. A nephrectomy was performed transperitoneally. A huge, reddish blue, tense, thin-walled, cystic mass was obtained, measuring 37.5 by 23.0 by 13.0 cm. The collapsed hydronephrotic same weighed 570gm. The obstruction which had caused the giant hydronephrosis was found at 2.5cm. distant portion of the ureter below uretero-pelvic junction. This point was 1.5 cm. in length, hard and cicatriciallydistorted. There was dense adhesion between distorted portion of ureter and periureteral tissue. These caused occlusion of the ureteral lumen.
