Examinations under conditions of diuresis produced by drugs can be useful to differentiate pyelo-ureteric obstruction from a dilated collecting system with normal flow. 22 infants with 42 kidneys showing moderate dilatation of one of both renal collecting systems were examined by sonography and excretory urography under conditions of diuresis and the results were compared. Depending on the radiological appearances and contrast clearance rates, four diagnostic groups could be identified; these also differed significantly on the sonographic examinations. In general, there was good agreement between the two methods. Carefully performed, diuresis sonography will clearly distinguish between urodynamically significant obstruction from a wide but non-obstructive collecting system. The number of radiographic examinations can therefore be reduced in these patients.
通过药物诱导利尿条件下的检查，有助于鉴别肾盂输尿管梗阻与具有正常血流的扩张集合系统。对22例婴儿的42个肾脏进行了研究，这些肾脏的一侧或双侧肾集合系统有中度扩张，在利尿条件下通过超声检查和排泄性尿路造影进行检查，并对结果进行比较。根据放射学表现和造影剂清除率，可分为四个诊断组；在超声检查中这些组也有显著差异。总体而言，两种方法之间有较好的一致性。仔细进行的利尿超声检查能够清楚地区分具有尿动力学意义的梗阻与广泛但无梗阻的集合系统。因此，这些患者的放射学检查次数可以减少。
