为了解利尿Ｂ超诊断小儿肾盂输尿管连接部梗阻（ＰＵＪＯ）的意义，对２５例（３４侧）小儿肾积水进行利尿Ｂ超检查，将检查结果与ＩＶＵ、肾盂测压、手术中所见病理改变及正常肾脏检查结果进行比较。结果显示利尿后ＰＵＪＯ患儿肾脏集合系统明显扩大，平均较利尿前扩大１０５％，利尿后９０ｍｉｎ仍不能恢复。同返流、输尿管远端或下尿路梗阻引起的肾积水及正常肾脏检查结果比较有显著性差异（Ｐ＜０．０５）。利尿Ｂ超可作为判断ＰＵＪＯ的方法之一。

To understand the significance of diuretic B-ultrasonography in the diagnosis of pediatric ureteropelvic junction obstruction (PUJO), diuretic B-ultrasound was performed in 25 cases (34 sides) of children with hydronephrosis, and the results were compared with those of IVU, pyelography, pathology Changes and normal kidney test results were compared. The results showed that after diuresis in PUJO children kidney collection system was significantly expanded, an average of 105% more than before diuresis, 90min after diuretic still can not be restored. With reflux, distal ureter obstruction or urinary tract obstruction caused by hydronephrosis and normal kidney test results were significantly different (P <0.05). Diuretic B-can be used as one of the ways to judge PUJO.
