回顾性分析了354例小儿肾活检术的并发症及其分布。结果：342例获得了足够的肾组织提供了明确的诊断，成功率为96.6％。术后有27例发生了并发症（7．6％），其中肉眼血尿22例（6．2％），疼痛15例（42％），肾包膜下血肿11例（3．1％），血凝块栓塞9例（2．5％），肾内动静瘘1例（O．28％）。并发症的发生与肾小球疾病的性质、肾功能及单针穿刺所取出肾组织的长度有关，而与患儿年龄及穿刺次数无关。小儿经皮肾活检术是一种相对安全而有效的检查方法。
Retrospective analysis of 354 cases of pediatric renal biopsy complications and their distribution. Results: A clear diagnosis was obtained in 342 patients with adequate renal tissue with a success rate of 96.6%. Complications (7.6%) occurred in 27 patients (22%), of which 22 (6.2%) were gross hematuria, 15 (42%) were pain, and 11 (3.1%) were subrenal hematomas 9 cases of clot embolization (2.5%), 1 case of renal arteriovenous fistula (O.28%). Complications occurred with the nature of glomerular disease, renal function and the length of the kidney removed by a single needle puncture related to the age and number of punctures has nothing to do. Percutaneous renal biopsy in children is a relatively safe and effective method of examination.
