A review of percutaneous nephrostolithotomy (PNL) done at Nottingham, City Hospital during January 1985 to April 1987 was undertaken. During this period 113 patients underwent the procedures. The study was confined to 92 patients who had complete case records. Initially 81 patients successfully had percutaneous nephrostolithotomy. Simple extraction were done in 21 (22.8%) patients, USL in 55 (56.5%) while a combination of USL and EHL was done in 8 (8.7%) patients. The overall stone clearance without further manipulations, was 70.6% but with further manipulations the clearance rate rose to 84.8%, suggesting that with increased expertise, one would expect the clearance to be near 100%.
对1985年1月至1987年4月在诺丁汉市立医院进行的经皮肾镜取石术（PNL）进行了回顾。在此期间，113例患者接受了该手术。该研究限于92例有完整病例记录的患者。最初，81例患者成功进行了经皮肾镜取石术。21例（22.8%）患者进行了单纯取石，55例（56.5%）患者进行了超声碎石术（USL），8例（8.7%）患者进行了超声碎石术和电子液压碎石术（EHL）联合治疗。未经进一步处理的总体结石清除率为70.6%，但经过进一步处理后，清除率升至84.8%，这表明随着专业技术的提高，预计清除率将接近100%。
