目的 :探讨输尿管镜下气压弹道碎石治疗输尿管结石的临床效果。方法 :对 2 5 2例输尿管结石患者采用该法治疗的情况进行回顾分析。结果 :2 5 2例中 2 38例治疗成功 ,成功率为 94.4% ,8例输尿管镜放置失败 ,输尿管镜插入成功率为 96 .8% (2 44 / 2 5 2 ) ,6例结石未能完全粉碎 ,腔内碎石成功率为 97.1% (2 38/ 2 44 )。结论 :输尿管镜下气压弹道碎石治疗输尿管结石疗效确切 ,患者痛苦小 ,术后恢复快 ,是输尿管结石的较为满意的治疗方法。

Purpose:To investigate the clinical effects of pneumatic lithotripsy (PL) under a ureteroscope for the treatment of ureteral stones.Method:From April 1996 to April 2000,252 patients with ureteral stones undergoing PL was retrospectively analyzed.Results:Among 252 cases, 238 had a satisfactory therapeutic effects with the successful rate being 94.4 %.8 cases failed to placement of ureteroscope and the successful rate for the insertion of ureteroscope was 96.8 % (244/252). During operation, ureteral stones in 6 cases were not dealt with well with the successful rate of PL being 97.1 % (238/244).Conclusion:The therapeutic effects of PL under ureteroscope in the treatment of ureteral stones were reliable and the recovery after operation was rapid.PL was an ideal therapy for ureteral stones.
