The Yorkshire Lithotriptor Centre acquired a Candela MDL-2000 LaserTripter and a 7.2F Miniscope in February 1990. We present the results obtained in the first 200 patients referred for treatment of ureteric stones or stone fragments. Of 175 patients who were evaluable, 58 had upper ureteric stones, 41 mid-ureteric and 76 lower ureteric stones. Successful laser fragmentation was achieved in 77% of cases and a further 10% were rendered stone-free by the push-bang technique. Ureterolithotomy was required in 9% and the major complication rate was 4%. Ureteric dilatation was not used. Maximum laser energy was required to break 19% of the stones, but no stone was encountered which could not be broken. Laser lithotripsy with this system is highly effective at all levels of the ureter; it is safe and it complements ultrasound-guided extracorporeal lithotripsy.
约克郡碎石中心于1990年2月购置了一台坎德拉MDL - 2000激光碎石机和一台7.2F微型内窥镜。我们展示了首批200例因输尿管结石或结石碎片前来治疗的患者所取得的结果。在175例可评估的患者中，58例患有上段输尿管结石，41例患有中段输尿管结石，76例患有下段输尿管结石。77%的病例实现了成功的激光碎石，另有10%通过推撞技术实现了无石状态。9%的患者需要进行输尿管切开取石术，主要并发症发生率为4%。未使用输尿管扩张术。19%的结石需要最大激光能量才能破碎，但未遇到无法破碎的结石。使用该系统进行激光碎石术在输尿管各段均非常有效；它是安全的，并且是超声引导体外碎石术的补充。
