目的:探讨应用微创经皮镜取石术(MPCNL)治疗重复肾肾结石方法的疗效及安全性。方法:我们选取从2009年11月～2012年11月在我院进行治疗的28例重复肾肾结石患者,男性15例,女性13例,平均年龄为36.5±1.2(20～70岁),记录患者结石的大小及位置。为患者签订知情同意书后进行手术治疗。结果:术中平均出血量为25.6±8.9(10～50)ml,平均手术时间为:56.3±6.5(30～100)分钟,结石清除率(SFR)为89.3%,另外3例存在少量碎石残留的患者改形ESWL术后结石全部排除。所有患者随访过程中未见并发症及结石复发。结论:应用微创经皮镜取石术(MPCNL)治疗重复肾肾结石是一种安全且有效的手术方法,值得在临床上推广。
Objective: To investigate the efficacy and safety of minimally invasive percutaneous vitrectomy (MPCNL) in the treatment of patients with recurrent renal calculi. METHODS: We selected 28 patients with recurrent nephrolithiasis who were treated in our hospital from November 2009 to November 2012. There were 15 males and 13 females, with an average age of 36.5 ± 1.2 (20-70 years) The size and location of the patient’s stone. Surgical treatment was performed after the patient’s informed consent was signed. Results: The mean intraoperative blood loss was 25.6 ± 8.9 (10 ~ 50) ml, the average operation time was 56.3 ± 6.5 (30 ~ 100) minutes, the stone clearance rate (SFR) was 89.3% and the other 3 cases had small amount of gravel Residual patients after ESWL remodeling stones were excluded. All patients were followed up no complications and stone recurrence. Conclusion: The application of minimally invasive percutaneous vitrectomy (MPCNL) in the treatment of recurrent renal calculi is a safe and effective surgical method, which is worthy of clinical application.
