上尿路扩张的80个输尿管肾单元（65例）进行了压力灌注研究和利尿肾造影，间隔时间短。压力灌注研究按照Whitaker的建议进行评估，同时通过计算峰值消除率定量分析利尿剂肾造影的冲洗曲线。上尿路容积由静脉尿路造影估计，并直接测量21例。通过基线肾功能图和血浆肌酐水平评估肾功能。在轻度上尿路扩张（< 30 ml）的患者中，88%的病例同意这两种手术，在大规模扩张（bbb70 ml）的患者中，只有58%的病例同意这两种手术。在后一种情况下，利尿剂肾脏扫描比压力灌注研究更容易阻塞。肾功能严重降低的影响不如大面积扩张的影响明显。在肌酐清除率为10ml min - 1或更低的患者中，尿流测量所反映的对氟塞胺的夸张反应证实了这一点。在8名肾功能严重下降的患者中，他们在手术过程中没有表现出完全的一致，其中6名患者出现了上尿路的大规模扩张。
Eighty ureterorenal units (65 patients) with upper urinary tract dilatation underwent pressure perfusion studies and diuresis renographies separated by short intervals. Pressure perfusion studies were evaluated as suggested by Whitaker, while wash-out curves of diuretic renographies were analysed quantitatively by calculating peak elimination rates. Upper urinary tract volume was estimated from iv urographies and measured directly in 21 cases. Renal function was assessed from base-line renograms and plasma creatinine levels. In patients with minor upper urinary tract dilatation (< 30 ml) the two procedures agreed in 88% of cases, in those with massive dilatation (> 70 ml) agreement was limited to 58%. Diuretic renal scans were more often obstructed than pressure perfusion studies in the latter situation. The effect of severely reduced renal function was less prominent than that of massive dilatation. This was confirmed by the exaggerated response to frusemide reflected by urinary flow measurements in patients with a creatinine clearance of 10 ml min− 1 or less. Of the eight patients with severely reduced renal function, who did not show full agreement between the procedures, six had massive dilatation of the upper urinary tract.
