Between June, 1984 and May, 1988, 22 cases of renal injury were treated. There were 13 males and 9 females. The most frequent causes were traffic accidents (13 cases) and the next were falls (7 cases). Associated injuries were seen in 9 cases, including bone fractures, head injuries, liver lacerations, hemothorax and splenic laceration. Out of the 22 patients, there were 13 cases of renal contusion, 6 cases of renal laceration, 1 case of renal rupture and 2 cases of pedicle injury. Evaluation was made by IVP, CT, arteriography and so on. Arteriography was the most useful method whether immediate surgery should be done or not. Three cases were treated surgically (2 nephrectomies for rupture and pedicle injury, 1 drainage for laceration). The other cases were treated conservatively and no complications have been seen.
