Twenty-seven patients underwent percutaneous ureteral perfusion after successful surgical repair of ureteropelvic junction obstruction in order to determine the perfusion pressures in ureters without obstruction. In each patient, the postoperative ureteropelvic junction appeared widely patent and the rest of the ureter appeared entirely normal. Ureteral perfusion was performed via percutaneous puncture of the collecting system; the pressure in the pelvis was measured through this needle and bladder pressure was monitored through a urethral catheter. "Absolute" (renal pelvic) and "differential" (renal pelvic minus bladder) pressures were measured at 10, 15, and 20 ml/min perfusion rates. Absolute and differential pressures rose as the perfusion rates increased; absolute pressure rose but differential pressure fell as the bladder was filled. The upper limit of normal differential pressure encountered with the bladder empty was 13 cm of water during perfusion at 10 ml/min.
27例患者在输尿管肾盂连接部梗阻手术修复成功后接受了经皮输尿管灌注，以确定无梗阻输尿管的灌注压力。每位患者术后输尿管肾盂连接部均显示通畅，输尿管其余部分完全正常。通过经皮穿刺集合系统进行输尿管灌注；通过该针测量肾盂压力，并通过尿道导管监测膀胱压力。在灌注速率为10、15和20ml/min时测量“绝对”（肾盂）压力和“压差”（肾盂压力减去膀胱压力）。随着灌注速率增加，绝对压力和压差均升高；随着膀胱充盈，绝对压力升高但压差降低。膀胱空虚时，灌注速率为10ml/min时遇到的正常压差上限为13cm水柱。
