A review of ultrasonographic urotract controls was done in 487 children (390 female and 97 male) in whom subureteral Teflon paste had been endoscopically infected in order to avoid vesicoureteral reflux. Dilatation of the upper urinary tract was visualized in 91 of 732 ureters (12.43%). Upper urotract dilatation may be either a sign of the obstruction of ureterovesical junction caused by Teflon or recurrence of vesicoureteral reflux. Echosonographically, 4 types of dilatation were disclosed, each having, a particular diagnostic or therapeutic approach. Acute dilatations associated with pain (2 patients-0.4%) were subjected to emergency surgery (ureterocystoneostomy). Chronic dilatation, which did not abate even after 4 weeks (6 ureters-0.81%) was identically treated. A temporary dilatation usually withdrew spontaneously after 1-2 weeks (66 ureters-9.01%). Patients with delayed occurrence of intermittent dilatation (17 ureters-2.32%) underwent control micturating cystosonography for suspected reflux recurrence.
对487名儿童（390名女性和97名男性）进行了超声泌尿系统检查回顾，这些儿童为避免膀胱输尿管反流而在内镜下注射了输尿管下聚四氟乙烯糊剂。在732条输尿管中的91条（12.43%）可见上尿路扩张。上尿路扩张可能是聚四氟乙烯导致输尿管膀胱连接处梗阻的迹象，也可能是膀胱输尿管反流复发的迹象。超声检查发现了4种类型的扩张，每种类型都有特定的诊断或治疗方法。与疼痛相关的急性扩张（2例，占0.4%）接受了急诊手术（输尿管膀胱吻合术）。即使4周后仍未缓解的慢性扩张（6条输尿管，占0.81%）也进行了同样的治疗。暂时性扩张通常在1 - 2周后自行消退（66条输尿管，占9.01%）。间歇性扩张出现延迟的患者（17条输尿管，占2.32%）因怀疑反流复发而接受了排尿性膀胱超声检查。
