過去4年間に経験した腎外傷22例について臨床的観察を行った.1)男性若年者にやや多く,約60%は交通事故によるものであった.2)腎外傷度分類で挫傷13例,軽度裂傷4例,高度裂傷2例,破裂1例,腎茎断裂2例であった.3)保存的治療19例,腎摘除術2例,血腫除去術1例であった.死亡例はなかった.4)診断にはCT,血管造影が有用であり,とくに後者は即時手術の適応の決定に有用であった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.
