由于剧烈运动、自行车、摩托车和汽车事故的频繁发生,儿童肾损伤也日益增多,但文献报告则极少。作者最近治疗2例,并复习1958～1973年间住院的57例,认为处理此种损伤的关键在于有效和迅速的分类方法、放射学检查与及早决定采用保守或手术治疗。肾损伤的分类按Nunn(1962)分为四型: 1.肾挫伤有外伤史、体检时有或无肾区损伤、血尿、肾盂造影无肾功能减损、肾盂肾盏损伤或造影 Kidney injuries are also increasing in children due to strenuous exercise, bicycle, motorbike and car accidents, but few are reported in the literature. The author recently treated 2 cases and reviewed 57 cases hospitalized between 1958 and 1973. The key to dealing with this type of injury was the effective and rapid classification, radiological examination and early decision to adopt conservative or surgical treatment.
