上尿路梗阻患者的尿路动力学测定,在诊断及治疗上都是必要的。但以往的测定方法,还不能提供满意的判断标准。本文为治疗目的,对肾造瘘患者利月染色盐水测定流体压力,进行了上尿路动力学研究。14例肾积水,3例肾结石患者治疗过程中均行肾造瘘,肾结石术后无梗阻问题作为对照。经造瘘管注入 Urinary tract dynamics in patients with upper urinary tract obstruction, in the diagnosis and treatment are necessary. However, the previous measurement methods, but also can not provide a satisfactory standard of judgment. The purpose of this article for the treatment of nephrostomy in patients with stained saline for the determination of fluid pressure on the urinary tract dynamics. 14 cases of hydronephrosis, 3 cases of patients with kidney stones during treatment of renal fistula, kidney stones without obstruction after surgery as a control. After fistula injection
