急性肾损伤121例临床与病理分析

目的 探讨儿童急性肾损伤(AKI)发病情况、病因、病理改变及病程转归情况.方法 回顾性分析2005年9月-2010年9月本院儿肾科收治的所有AKI患儿发病情况、临床诊断、病理诊断、住院天数及预后资料.采用SPSS 13.0软件进行分析.结果 共收治AKI患儿121例,每年儿童AKI人数/每年因肾脏疾病住院人数呈递增趋势,其中70例患儿进行了肾活检.121例AKI患儿中,男79例,女42例,发病年龄1~14岁[(7.6±3.8)岁],临床诊断前4位分别为急性感染后肾炎,肾病综合征,溶血尿毒综合征和急性间质性肾炎;病理诊断前4位分别为系膜增生性肾小球肾炎,毛细血管内皮细胞增生性肾小球肾炎,间质性肾炎和狼疮肾炎.所有AKI患儿中61例行血液透析,5例行腹膜透析,其余患儿对症保守治疗后好转.治疗后完全康复95例(78.51%),部分康复24例(19.83%),维持性透析治疗2例(1.66%).AKI衰竭期患儿住院时间(25.6±6.8) d,明显长于AKI危险期和损伤期患儿,且预后差.结论 儿童AKI的病因以感染性疾病为主,尤以感染后肾小球肾炎和间质性肾炎为主,但狼疮肾炎有逐年增多趋势,易并发肾功能不全.肾实质性AKI患儿均应行肾活检以明确病因,进行有效治疗.早期诊断、及时治疗是改善AKI预后的关键.
