13歳女,12歳男IVP上尿管の描出があれば,尿溢流を認めた場合でも開放手術や早急なドレナージをせずに,まず保存的治療を第一選択にすべきであるTwo cases of major blunt renal trauma with urinary extravasation managed by conservative treatment are presented herein. The first case: A 13-year-old girl fell from a bicycle. A computed tomographic (CT) scan showed right renal laceration with retroperitoneal hematoma. Renal arteriography showed evidence of fresh arterial bleeding without visualization of the lower pole. She was treated conservatively with superselective arterial embolization of the lower pole. She developed no urinoma with normal renal function. Renal renin and blood pressures stayed within the normal range in follow up studies. The second case: A 12-year-old boy fell from a tree and hit his right flank. A CT scan showed fragmentation of right renal cortex with retroperitoneal hematoma. He was treated conservatively as his vital signs remained stable, no active arterial bleeding was found no renal arteriography and both renal pelvis and ureters were well visualized by intra venous pyelography. Retroperitoneal hematoma was absorbed without formation of urinoma. Renal function remained within normal limits in follow up studies.
