Objective To observe the therapeutic effect of treatment by utilizing double J tube continuous reflux perfusion of bladder to perform percutaneous nephrolithotomy in the treatment of renal calculi without hydronephrosis. Methods 25 renal calculi patients without obvious hydronephrosis admitted to our hospital from September 2010 to May 2011 were selected to perform continuous perfusion of bladder through double J tube to form artificial hydronephrosis. Percutaneous nephrolithotomy was performed afterward. Results 25 cases were successfully established percutaneous minimally invasive channel. 23 patients were given single stone crushing,2 cases were given indwelling fistula to perform secondary gravel stone due to hemorrhage and orthostatic intolerance. There were no residual stones among the 20 patients who were given first - stage operation; there were no residual stones among the 2 patients who were given secondary PCNL ESWL was used to treat the 3 patients who had residual stones. The one - stage stone clearance rate was 80% ( 20/25 ). Conclusion By utilizing double J tube continuous reflux perfusion of bladder to implement percutaneous nephrolithotomy for renal calculus without hydronephrosis is safe and effective, and can be promoted clinical-ly.%目的 观察利用双J管膀胱持续逆流灌注施行经皮肾镜取石术(PCNL)治疗无积水肾结石的疗效.方法 选取我院2010年9月-2011年5月25例无明显肾积水的肾结石患者利用双J管膀胱持续灌注形成人工肾积水后,行微创PCNL治疗.结果 25例患者均利用双J管膀胱持续逆流灌注成功建立经皮肾镜微创通道并进行PCNL,其中23例患者进行一期单通道碎石取石,2例因出血和体位不能耐受,留置造瘘管后进行二期碎石取石.20例一期术后无结石残留;2例行二期PCNL后无结石残留;3例残留结石术后进行体外冲击波碎石术(ESWL)治疗,一期结石清除率80%(20/25).结论 利用双J管膀胱持续逆流灌注施行PCNL治疗无积水肾结石是安全、有效的,值得临床推广.
