【摘要】 对先天肾积水的病因研究以前主要着重于解剖和病理学方面。我们应用聚合酶链反应（ＰＣＲ）技术直接检测手术中从肾盂内取的尿液及肾盂输尿管连接处的病变组织，结果２５例患儿１１例检测出巨细胞病毒（ＣＭＶ）。对照组６例检测结果全部为阴性。二者经统计学处理结果有显著性差异（Ｐ＞０．０５）。提示ＣＭＶ感染可能是引起先天肾积水的原因之一。更多还原

【Abstract】 Hydronephrosis is one of the common congenital abnormalities, but its pathogeny is not clear, We used polymerase chain reaction (PCR) to detect CMV in urine and the pathological tissues colected from the renal pelvis and ureter,11 out of the 25 hydronephrosis patients were positive (to CMV positive urine in 6 cases and positive pathological tissues in 8 cases). All specigested that CMV infection was associated with hydronephrosis and might be one of the causes to produce congenital hydronephrosis.更多还原
