目的对于应用新型封堵器在输尿管镜下碎石的安全性及有效性的探讨.方法回顾性分析我院自2011年10月至今采用德国STORZ F8/9.8输尿管镜结合上海英诺伟公司的结石封堵器治疗输尿管结石患者65例,其中男性45例,女性20例,其中上段结石25例,中段结石25例,下段结石15例,结石直径5mm-13mm.在输尿管镜下气压弹道碎石过程中配合使用上海英诺伟TMIVX-SCIO输尿管管路封堵器进行封堵.结果总碎石率99.0%,无一例输尿管穿孔及粘膜撕脱等严重并发症,术后复查平片结石无有意义结石残留(残留结石均小于3mm),除早期由于操作不熟悉致一上段结石漂移至肾盂,其余均获得成功碎石.结论输尿管管路封堵器能显著减少输尿管碎石术中结石漂移、提高结石清除率,临床应用价值高、治疗成本低且使用安全,尤其对于解决上段结石在碎石过程中返回肾盂这一问题有很大帮助.“,”Objective To exeplore the security and effectiveness of ureteroscopic pneumatic lithotripsy for treatment of ureteral stones with INNOVEX TMIVX—SCIO ureteral occlusion device . Methods 65 cases of patients with ureteral calculi on the treatment by the F9.8 STORZ ureteroscopy made in Germany and the INNCIVEXTM IVX-SC10 ureteral occlusion devic made in Shanghai were retrospectively analyzed ,among al cases male 45 cases, female 20 cases, 25 cases of upper ureteral stone, 25 cases of stones in the middle ureteral, and lower ureteral stone in 15 cases, stone diameter 5mm-13mm. Results The total lithotripsy success rate was 99.0%, There were neither peri—operative complications in our study nor the septicemia.The clinical review by the K.U.B and CT scan carried out 4 weeks after the surgery.In 64 cases,there was no more significant residual calculus.The successful rate of the ureteroscopic pneumatic lithotripsy with the ureteral occlusion device was 99%. Conclusions The ureteral occlusion device was very useful and safe inpreventing the stone migration and in facilitating the calculus evacuation.Further pro—speetive randomized controled clinical trial with large cohort should be carried out to summarize the clinical value of this ureteral occlusion device.
