目的探讨微创经皮肾镜取石术(m PCNL)治疗肾下盏结石的临床疗效及安全性。方法收集2013年2月至2014年6月我院收治的肾下盏结石108例患者资料,将患者完全随机分为对照组和观察组,各54例。观察组患者给予m PCNL治疗,对照组患者根据临床资料一对一选取体外冲击波碎石术(ESWL)治疗。观察并比较两组患者的疗效与并发症情况。结果观察组患者的腰部不适消失率、患者满意率均明显高于对照组,且结石残留率、并发症发生率均明显低于对照组,差异均有统计学意义(均P<0.05)。结论在严格掌握适应证的前提下,与ESWL比较,对最大直径1.0~2.0 cm肾下盏结石,m PCNL治疗结石清除率更高,并有助于缓解患者肾区不适、血尿等症状,改善患者生活质量,且安全可靠。
Objective To investigate the clinical efficacy and safety of minimally invasive percutaneous nephrolithotomy (m PCNL) in the treatment of lower calyx stones. Methods The data of 108 patients with subrenal calculus in our hospital from February 2013 to June 2014 were collected and randomly divided into control group and observation group with 54 cases in each group. Patients in the observation group were treated with m PCNL, and patients in the control group were treated with one-on-one extracorporeal shock wave lithotripsy (ESWL) according to clinical data. The curative effect and complication of the two groups were observed and compared. Results In the observation group, the rate of lumbar discomfort and patient satisfaction were significantly higher than those in the control group, and the residual rate of stone and the complication rate were significantly lower than those in the control group (all P <0.05). Conclusion Under strict indications, compared with ESWL, the clearance rate of m PCNL stones in calcification of 1.0 ~ 2.0 cm in diameter of the kidney is higher, and it is helpful to relieve the symptoms such as kidney discomfort, hematuria, Patients quality of life, and safe and reliable.
