CO2气膀胱膀胱镜应用于输尿管膀胱壁段结石手术

目的探讨CO2气膀胱膀胱镜输尿管膀胱壁段结石电勾切开取石手术的安全性及有效性。方法8例患者均为单侧输尿管膀胱壁段结石。建立气膀胱，压力8～10mmHg，下腹部建立1～2个5mm曲卡，以30。膀胱镜作观察镜行患侧输尿管膀胱壁段结石电切取石手术。结果手术均获成功，手术时间20～40mnin术中估计出血0-5ml，术后1周拔导尿管，住院3～5d，术后1个月膀胱镜下拔双“J”管，无尿瘘发生。随访3～6个月，症状消失，肾积水消失，膀胱造影无返流。结论气膀胱输尿管膀胱壁段结石电勾切开取石手术是治疗输尿管膀胱壁段结石安全有效的微创手术方式。

CO2 Gas Bladder Cystoscopy in Operation of Patients with Ureterovesical Junction Stones

Objective： To investigate the safety and efficacy in treatment of patients with ureterovesical junction stones via CO2 gas bladder cystoscopy. Methods： CO2 gas bladder was used for eight patients with ureterovesical junction stones by pressure of 8-10 mmHg, 5 mm Trocar in lower abdomen, and 30 ~ cystoscope for ureterovesical junction stone removal. Results： The surgery had been successful, with operation time of 20-40 mins, estimated intraoperative hemorrhage of 0-5ml and in hospitalization of 3-5 days. One week later, the catheters were pulled out, and one month later the double ＂J＂ tubes were pulled out, with no urinary fistula occurance. Follow-up of 3-6 months, the symptoms and hy- dronephrosis disappeared without reflux cystography. Conclusion： Gas bladder cystoscopy is a safe, effective, minimally invasive surgical approach for patients with ureterovesical junction stones.
