经皮肾镜取石术治疗体外冲击波碎石治疗失败肾结石患者的应用效果

Application effect of percutaneous nephrolithotomy in the treatment of patients with failed renal calculi under the therapy of extracorporeal shock wave lithotripsy

目的探讨经皮肾镜取石术治疗体外冲击波碎石治疗失败肾结石患者的应用效果。方法选取2017年2月～2018年2月我院收治的60例体外冲击波碎石治疗失败肾结石患者作为研究对象,按照电脑随机分组方法将其分为观察组(30例)与对照组(30例)。观察组患者采用经皮肾镜取石术方法治疗,对照组患者继续采用体外冲击波方法治疗。比较两组患者的住院时间、手术时间、结石清除率、治疗总有效率及并发症总发生率。结果观察组患者的住院时间为(5.21±0.11)d,手术时间为(80.21±1.27)min,均短于对照组的(6.23±1.45)d、(90.11±1.25)min,差异有统计学意义(P<0.05)。观察组患者的结石清除率为93.33%,显著高于对照组的66.67%,差异有统计学意义(P<0.05)。观察组患者的治疗总有效率为90.00%,显著高于对照组的63.33%,差异有统计学意义(P<0.05)。观察组患者的并发症总发生率为13.33%,显著低于对照组的26.67%,差异有统计学意义(P<0.05)。结论采用经皮肾镜取石术治疗体外冲击波碎石治疗失败肾结石患者的效果显著,能明显提高结石清除率,提高治疗有效率,促进肾结石患者早期康复。

Objective To investigate the application effect of percutaneous nephrolithotomy in the treatment of patients with failed renal calculi under the therapy of extracorporeal shock wave lithotripsy. Methods Sixty patients with failed renal calculi under the therapy of extracorporeal shock wave lithotripsy from February 2017 to February 2018 in our hospital were enrolled in this study. The patients were divided into the observation group (30 cases) and the control group (30 cases) according to the computer randomization. In the observation group, percutaneous nephrolithotomy was used, while in the control group, extracorporeal shock wave lithotripsy was used continuously. The hospitalization time, operation time, stone removal rate, total effective rate of treatment, and total incidence rate of complications were compared between the two groups. Results The hospitalization time of the observation group was (5.21±0.11) d, the operation time was (80.21±1.27) min, which were shorter than those of the control group accounting for (6.23±1.45) d and (90.11±1.25) min, and the differences were statistically significant (P<0.05). The stone removal rate of the observation group was 93.33%, which was significantly higher than that of the control group accounting for 66.67%, and the difference was statistically significant (P<0.05). The total effective rate of treatment in the observation group was 90.00%, which was significantly higher than that in the control group accounting for 63.33%, and the difference was statistically significant (P<0.05). The total incidence rate of complications in the observation group was 13.33%, which was significantly lower than that in the control group accounting for 26.67%, and the difference was statistically significant (P<0.05). Conclusion The application of percutaneous nephrolithotomy in the treatment of patients with failed renal calculi under the therapy of extracorporeal shock wave lithotripsy can obtain a remarkable effect, which can greatly increase the removal rate of stones as well as therapeutic effectiveness rate, and promote the early rehabilitation of patients with renal calculi.
