EFFECT OF PREOPERATIVE PLACEMENT OF DOUBLE-J URETERAL CATHETER ON COMPLICATIONS OF FLEXIBLE URETEROSCOPIC LITHOTRIPSY FOR KIDNEY STONES
Objective To investigate the effect of preoperative placement of double-J ureteral catheter on complications of flexible ureteroscopic lithotripsy for kidney stones.Methods A total of 218 patients with kidney stones who underwent flexible ureteroscopic lithotripsy were enrolled.According to whether a double-J ureteral catheter was placed before surgery,these patients were divided into preoperative placement group (131 patients) and conventional group (87 patients).The two groups were compared in terms of time of operation,length of postoperative hospital stay,and complications.Results There were significant differences between the two groups in time of operation,length of postoperative hospital stay,success rate of ureteral sheath placement,ureteral injuries,intraoperative bleeding,postoperative hematuria,urinary-derived sepsis,formation of steinstrasse,and incidence of residual stones in kidney (t=7.19,6.18;x2 =4.26-9.39;P<0.05).Conclusion Preoperative placement of double-J ureteral catheter before flexible ureteroscopic lithotripsy can significantly reduce time of operation,length of postoperative hospital stay,and number of complications.
