The application of hanging catheters (stents) in operations for hydronephrosis in children has considerable advantages over classical (open) methods of drainage. Bacteriological investigations of analyses of urea performed in open and closed closed systems of drainage have shown less incidence of infection of the upper urinary tracts with intrahospital gram-negative flora after operation on patients operated upon with using stents, which gave less amount of postoperative complications.
在儿童肾盂积水手术中应用悬挂导管（支架）比传统的（开放）引流方法具有相当大的优势。对开放和封闭引流系统中尿素分析进行的细菌学调查显示，在使用支架进行手术的患者术后，医院内革兰氏阴性菌引起的上尿路感染发生率较低，术后并发症也较少。
