小儿肾损伤较成人多见,这与小儿的局部解剖特点有关,其中主要的是小儿肾脏体积相对较大,缓冲打击力量的肾脂肪囊和腰部肌肉发育不好。肾脏位置较低并伴有尿路梗阻症状的先天性发育异常,很易损伤。作者1962～1973年共治疗150例肾损伤患儿:闭合性损伤147例,开放性损伤仅3例。最多的一组(110例)是10～15岁男孩。肾发育异常者10例:先天性肾积水6例,重复肾2例,马蹄肾1例,盆腔异位先天性联合肾1例。闭合性肾损伤中,从高处掉下或落在硬物上120例,直接打击腰部14例,挤压伤13例。
Kidney injury in children more common than adults, which is related to the local anatomy of children, of which the main is the relatively large volume of children’s kidneys, buffering power of the kidney fat capsule and waist muscular dysplasia. Lower renal position and congenital urinary tract obstruction associated with dysplasia, it is easy to damage. A total of 150 children with renal injury were treated from 1962 to 1973: 147 cases of closed injury and only 3 cases of open injury. The largest group (110 cases) were boys aged 10 to 15 years. Kidney dysplasia in 10 cases: congenital hydronephrosis in 6 cases, 2 cases of repeated kidney, horseshoe kidney in 1 case, pelvic ectopic congenital anastomosis in 1 case. Closed renal injury, falling from a height or falling on the hard object in 120 cases, directly against the waist in 14 cases, crush injury in 13 cases.
