目的探讨微创双导管超声碎石术治疗复杂肾结石临床效果。方法 47例复杂肾结石患者作为本次研究观察对象,所有患者均采用微创双导管超声碎石术进行治疗。并观察患者术后碎石成功率及结石清除率,对治疗效果进行总结和分析。结果 47例复杂肾结石患者,一期手术成功44例,结石清除率为93.6%。一期碎石手术时间为(58.4±10.9)min,术中出血量(176.3±8.9)ml,3例患者在一期手术治疗基础上配合二期手术治疗,1例患者需行三期手术。患者术后肾结石碎石成功率为100%。术后留置管在体内留置时间10~50 d,术后出现血尿3例(6.4%),经过相应治疗,1~4 d后症状消失,2例(4.3%)发生伤口感染,处理后感染消除。所有患者均未出现高热和脓尿等并发症。结论微创双导管超声碎石术治疗复杂肾结石效果明显,安全有保证,且结石清除率高,术后病发症较少,是目前治疗复杂肾结石的良好选择。
Objective To investigate the clinical effect of minimally invasive dual catheter ultrasound lithotripsy in the treatment of complex renal calculi. Methods 47 patients with complex renal calculi as the object of this study, all patients were treated with minimally invasive bi-port ultrasonic lithotripsy. And observe the success rate of postoperative gravel and stone removal rate, the treatment effect is summarized and analyzed. Results 47 cases of complicated kidney stones, a successful operation in 44 cases, stone clearance rate was 93.6%. The operation time of the first gravel was (58.4 ± 10.9) min and the amount of bleeding during the operation was (176.3 ± 8.9) ml. Three patients were treated with the second-stage operation on the basis of the first-stage operation. One patient needed three-stage operation. Postoperative renal stone gravel success rate was 100%. Postoperative indwelling catheter in the body indwelling time 10 ~ 50 d, postoperative hematuria in 3 cases (6.4%), after the corresponding treatment, 1 to 4 days after the symptoms disappeared, wound infection occurred in 2 cases (4.3%), after treatment, eliminate infection . All patients did not appear complications such as fever and pyuria. Conclusion Minimally invasive dual-guided ultrasound lithotripsy is effective in treating complex renal calculi, with safety and assurance, high stone clearance rate and less postoperative morbidity. It is a good choice for the treatment of complex renal calculi.
