Abstract
Objective: To investigate fluid absorption and its influencing factors during flexible ureteroscopic lithotripsy with intelligent control of renal pelvic pressure (RPP).
Methods: A total of 80 patients with upper urinary tract calculi underwent flexible ureteroscopic lithotripsy with intelligent control of RPP and were randomly divided into four groups. The RPP of Groups A, B, and C were set at -5 , 0 and 5 mmHg, respectively. Conventional flexible ureteroscopic lithotripsy with uncontrolled pressure served as control Group D. The perfusion flow rate was set at 100 ml/min in the four groups, with 20 patients in each group. The fluid absorption was measured by 1% ethanol every 10 minutes. Operation time, stone-free rate, and complications were recorded.
Result: Seventy-three patients were finally included in the RCT. The general and preoperative data of the patients were comparable between the groups. The fluid absorption of Groups A, B, and C was significantly less than that of Group D (P < 0.01). Fluid absorption and operation time were positively correlated, and the correlation coefficients R were 0.864, 0.896, 0.918, and 0.947, respectively (P<0.01). The fluid absorption of patients with vomiting, fever and ureteral injury was greater than that of patients without complications in the four groups (P < 0.01). In different groups, fluid absorption was greater in patients with ureteral injury PULS 1-3 than in noninjured patients (P<0.01).
CONCLUSION: Flexible ureteroscopic lithotripsy with intelligent control of RPP effectively reduces the absorption of perfusion fluid. Operation time and ureteral injury are also key factors affecting perfusion fluid absorption.
