改良输尿管支架留置技术对输尿管软镜钬激光碎石术患者的影响

目的 研究改良输尿管支架留置技术对输尿管软镜钬激光碎石术患者术后恢复及生活质量的影响。方法 选取2020年1月至2021年3月诸暨市中医医院收治的行输尿管软镜钬激光碎石术的120例患者为研究对象，将其按1∶1比例随机分为对照组和治疗组，每组各60例。对照组患者采用传统输尿管支架留置术，术后留置输尿管支架2周，治疗组患者采用改良输尿管支架留置术，术后第3天拔除支架。比较两组患者的并发症发生情况、清石率及生活质量。结果 治疗组患者的血尿、腰腹疼痛、支架表面石痂形成、尿路感染发生率均显著低于对照组（P<0.05）。两组患者术后1个月的总清石率比较无统计学意义（?2=0.901，P>0.05）。术后1个月，两组患者的健康调查量表36（36-item short form health survey，SF-36）各维度评分均显著高于本组术前（P<0.05），且治疗组患者的SF-36各维度评分均显著高于对照组（P<0.05）。结论 改良输尿管支架留置技术能获得与传统输尿管支架留置术相当的清石率，有利于降低输尿管支架留置术导致的并发症，提高生活质量。

Effect of modified ureteral stent indwelling technique on patients with flexible ureteroscope holmium laser lithotripsy

Objective To study the effect of modified ureteral stent indwelling technique on the recovery and quality of life of patients after flexible ureteroscope holmium laser lithotripsy. Methods A total of 120 patients who underwent flexible ureteroscope holmium laser lithotripsy in Traditional Chinese Medical Hospital of Zhuji from January 2020 to March 2021 were selected as the study objects, and they were randomly divided into control group and treatment group according to the ratio of 1:1, with 60 cases in each group. The control group received traditional ureteral stent indwelling for 2 weeks after surgery, and the treatment group received modified ureteral stent indwelling and the stent was removed on the 3rd day after surgery. The incidence of complications, stone removal rate and quality of life were compared between the two groups. Results The incidence of hematuria, lumbar and abdominal pain, formation of scab on the stent tube surface and urinary tract infection in treatment group were significantly lower than those in control group (P<0.05). There was no statistical significance in the total stone removal rate 1 month after surgery between the two groups (?2=0.901, P>0.05). One month after surgery, the scores of all dimensions of the 36-item short form health survey (SF-36) in both groups were significantly higher than those before surgery (P<0.05), and the scores of all dimensions of SF-36 in treatment group were significantly higher than those in control group (P<0.05). Conclusion The modified ureteral stent indwelling technology can achieve stone removal rate equivalent to that of traditional ureteral stent indwelling, which is beneficial to reduce the complications caused by ureteral stent indwelling and improve the quality of life.
