Moderate and even severe dilatation of the urinary tract in the absence of vesicoureteric reflux may remain stable or show spontaneous resolution. Two such cases are described. Twenty-five children with dilated urinary systems were studied to correlate the radiological, isotope, pressure perfusion and surgical findings. A positive Whitaker test correlated well with the surgical findings and post-operative improvement in renal function in all patients with pelviureteric junction (PUJ) and vesicoureteric junction (VUJ) obstruction. High flow rates of 8.6 and 12 ml are required even in neonates and infants in order to demonstrate obstruction by Whitaker testing.
在没有膀胱输尿管反流的情况下，泌尿系统的中度甚至重度扩张可能保持稳定或自行消退。本文描述了两例此类病例。对25例泌尿系统扩张的儿童进行了研究，以关联放射学、同位素、压力灌注和手术结果。在所有肾盂输尿管连接处（PUJ）和膀胱输尿管连接处（VUJ）梗阻的患者中，惠特克试验阳性与手术结果及术后肾功能改善密切相关。即使是新生儿和婴儿，为了通过惠特克试验证明梗阻，也需要8.6和12毫升的高流速。
