Two cases of congenital hydronephrosis discovered by renal trauma are reported. The first case was a 15-year-old girl. When she was practicing KENDO, her Hakama clung to her legs, and she tumbled. She had emergency operation for abdominal injury. At surgery, no evidence of abdominal injury was detected. Renal trauma was suspected. Right renal angiography revealed hydronephrosis. The second case was a 23-year-old girl, complaining of abdominal pain after stumbling over a block. Intravenous pyelography showed no visualization of the right kidney and CT scan showed an abnormal shadow. Retrograde pyelography and angiography revealed right hydronephrosis. Including our two cases, 47 cases of renal traumata occurring in hydronephrotic kidney in the Japanese literature were reviewed. Thirty five of these cases were males. Many were youths under the age of twenty. Various sports caused many of the renal traumata. 37 of these cases were treated by nephrectomy.
