Abstract:
Objective To investigate the safety and efficacy of ureteral access sheath (UAS) with vacuum suction during flexible ureteroscopic lithotripsy in the treatment of renal stones.Methods The clinical data on 56 patients with infectious renal stones who received flexible ureteroscopic lithotripsy were retrospectively analyzed.The patients were randomly divided into group A (26 patients) and group B (30 patients).Intrapelvic pressure,stoneclearance rate,surgical duration,formation of steinstrasse,postoperative fever (temperature ＞ 38.5 ℃C),PCT,leukocyte count,length of hospital stay,and hospitalization cost were evaluated.Results Intrapelvic pressure was much lower in group A than in group B;stone clearance rate was 96.2％ for group A and 83.3％ for group B;and surgical duration was (80.1 ± 2.2) min and (105.2 ± 3.5) min,respectively.One patient developed steinstrasse and one had postoperative fever in group A,while six patients developed steinstrasse and 4 had postoperative fever in group B;PCT and leukocyte count was much lower in group A than in group B.There were statistical differences between the two groups (P ＜ 0.05).The length of hospital stay and hospitalization cost were (7.4 ± 0.8)d and (20857.1 ± 389.4) RMB for group A and (8.2±1.3)d and (22008.5±394.3) RMB;but there were no statistical differences between the two groups (P ＞ 0.05).Conclusions Application of ureteral access sheath with vacuum suction during flexible ureteroscopic lithotripsy in the treatment of renal stones was safe and effective.It can shorten surgical duration,improve stoneclearance rate and reduce incidence of adverse reactions.This procedure has better value of clinical application.
