Emphasis is placed on the existence of two types of dilatation of the upper excretory tract: obstructive and non-obstructive lesions. Renal scintigraphy with technetium-labelled DTPA combined with a Lasilix test was performed in 34 patients (26 operated and 8 treated medically) with a total of 41 dilated renal units. Intra-operative exploration in the 17 reno-ureteral units assessed as being the site of obstruction on scintigraphy confirmed the lesion in the 14 cases of anomalies of the pyelo-ureteral junction and the 3 mega-ureters. For as long as the obstructed zone is not resected the dilated urinary tract fails to empty. In the other 12 units, the scintigraphy diagnosis of non-obstructive hypotony was confirmed by the operation and the subsequent course (notably in the 10 cases of reflux in the wide ureters reimplanted with a good result without resection of end of ureter).
梗阻性和非梗阻性病变。对34例患者（26例接受手术治疗，8例接受药物治疗）共41个扩张的肾单位进行了锝标记二乙三胺五乙酸肾闪烁扫描并联合速尿试验。在闪烁扫描中被评估为梗阻部位的17个肾输尿管单位进行了术中探查，证实了14例肾盂输尿管连接处异常和3例巨输尿管病例中的病变。只要梗阻区域未被切除，扩张的尿路就无法排空。在其他12个单位中，手术及后续病程证实了闪烁扫描诊断的非梗阻性张力减退（特别是在10例宽输尿管反流病例中，输尿管再植效果良好，未切除输尿管末端）。
