79例输尿管镜下行气压弹道碎石的疗效分析

目的 探讨输尿管镜下行气压弹道碎石的疗效以及此项技术的适应症和手术注意事项。方法回顾性分析我院79例采用输尿管镜下行气压弹道碎石的患者的临床资料，并进行总结分析。结果79例患者中，经一次输尿管镜下气压弹道碎石成功的患者为75例，占总数的94．94％。2例患者因输尿管狭窄导致置镜失败；1例患者置入输尿管镜后，因情况复杂，无法窥见结石情况；3例患者均采用开放手术进行取石，取石成功。术后，有2例患者出现输尿管穿孔，占总数的2．53％，予以双“J”管，经治疗后3个月无输尿管狭窄。患者均无严重并发症发生，满意度较高。结论输尿管镜下行气压弹道碎石，患者损伤小、结石排出成功率大，患者术后不良反应少，是临床治疗结石较好的方法，值得在临床推广使用。

Curative-effect analysis on 79 cases with downstream ureteroscopic pneumatic lithotripsy

Objective To explore the curative effect of downstream ureteroscopic pneumatic lithotripsy.its indications,and the surgical precaution points.Methods Retrospectively analyzed the clinical references of 79 patients who had downstream of ureteroscopic pneumatic lithotripsy in our hospital.Results Among the 79 patients.75 patients were successful after one ureteroscopic pneumatic lithotripsy,counted for 94.94%.Caused by mirror set,2 cases of ureteral stenosis failed;and 1 patient after implantation ureteroscopy,due to complicated circumstances,could not get a glimpse of stones;3 patients were treated with open surgery for stone,stone successed.After surgery.2 patients had ureteral perforation,counted for 2.53%;and treated them with double"J"tube;3 months after treatment.there was no ureteral stricture.There were no serious complications.Satisfaction was high.Conclusion Downstream ureterescopic pneumatic lithotripsy brings small damage to patients;its success rate of discharge of large stones is high;it causes fewer postoperative adverse events;it's a good way for clinical treatment.It is worthy in clinical use.
