【摘要】 目的 探讨输尿管软镜碎石取石术前留置双J管治疗肾结石的临床效果。方法 选取2018年1月至2020年6月收治的120例肾结石患者作为研究对象，根据双J管留置情况将其分为A组、B1组、B2组，各40例。三组均行输尿管软镜碎石取石术，术前A组不做任何处理，B1组留置双J管7 d,B2组留置双J管1个月。比较三组的治疗效果。结果 B1组、B2组的住院时间、手术时间长于A组，差异具有统计学意义（P<0.05）；三组的术后恢复时间比较，差异无统计学意义（P>0.05）。三组的通道鞘一次置入成功率比较，差异具有统计学意义（P<0.05）；三组的术后7 d及1个月结石清除率比较，差异无统计学意义（P>0.05）。B2组的通道鞘一次置入成功率、术后1个月结石清除率高于A组，差异具有统计学意义（P<0.05）。三组的尿路感染、输尿管壁损伤发生率比较，差异具有统计学意义（P<0.05）;B2组的尿路感染发生率高于A组，差异具有统计学意义（P<0.05）;B1组、B2组的输尿管壁损伤发生率低于A组，差异具有统计学意义（P<0.05）。结论输尿管软镜碎石取石术前留置双J管1个月可显著提高肾结石患者的通道鞘一次置入成功率、结石清除率，降低输尿管壁损伤发生率，但增加了尿路感染发生率，因此，对于双J管的具体留置时间应结合患者实际情况定夺。更多还原

【Abstract】 Objective To investigate the clinical effect of double J tube indwelling before ureteroscopic lithotripsy in the treatment of kidney stone. Methods A total of 120 patients with kidney stone treated from January 2018 to June 2020 were selected as the research objects. According to the double J tube indwelling situation, the patients were divided into group A, group B1 and group B2, with 40 cases in each group. Three groups underwent ureteroscopic lithotripsy. before operation, the group A did not do any treatment, the group B1 indwelled double J tube for 7 d and the group B2 indwelled double J tube for 1 month. The therapeutic effects among the three groups were compared. Results The hospital stay and operation time in the group B1 and the group B2 were longer than those in the group A, and the differences were statistically significant(P<0.05); there was no statistically significant difference in the postoperative recovery time among the three groups(P >0.05). There was statistically significant difference in the success rate of one-time implantation of channel sheath among the three groups(P <0.05); there was no statistically significant difference in the stone clearance rate at 7 d and 1 month after operation among the three groups(P>0.05). The success rate of one-time implantation of channel sheath and stone clearance rate at 1 month after operation in the group B2 were higher than those in the group A,and the differences were statistically significant(P<0.05). There were statistically significant differences in the incidences of urinary tract infection and ureteral wall injury among the three groups(P<0.05); the incidence of urinary tract infection in the group B2 was higher than that in the group A, and the difference was statistically significant(P<0.05); the incidence of ureteral wall injury in the group B1 and the group B2 was lower than that in the group A, and the difference was statistically significant(P <0.05). Conclusion Double J tube indwelling for 1 month before ureteroscopic lithotripsy can significantly improve the one-time implantation of channel sheath and stone clearance rate, reduce the incidence of ureteral wall injury, but increase the incidence of urinary tract infection. Therefore, the specific double J tube indwelling time should be determined in combination with the actual situation of patients.更多还原
