目的:评价微创经皮肾取石术治疗肥胖肾结石的疗效和安全性。方法:收集2007~2011年在我院行PCNL治疗的肾结石患者159例,并将患者分为三组:正常组(18.5≤BMI<24)、超重组(24≤BMI<28)和肥胖组(BMI≥28)。比较三组患者的外科治疗结果。结果:正常组、超重组及肥胖组结石清除率分别为92.3%、90.9%和89.7%,其他指标如住院时间、血红蛋白下降率、止痛药使用率、术后发热率等各组间差异无统计学意义。结论:采用PCNL治疗肥胖患者肾结石可取得同治疗正常体重患者类似的安全性和有效性。
Objective: To evaluate the efficacy and safety of minimally invasive percutaneous nephrolithotomy in the treatment of obese kidney stones. Methods: A total of 159 patients with kidney stones treated with PCNL in our hospital from 2007 to 2011 were divided into three groups: normal group (18.5≤BMI <24), overweight group (24≤BMI <28) and obesity group (BMI ≥28). Surgical treatment results were compared between the three groups. Results: The stone clearance rates of normal group, overweight group and obesity group were 92.3%, 90.9% and 89.7% respectively. There were no statistical differences among the other groups such as length of hospital stay, hemoglobin decline rate, painkiller utilization rate and postoperative fever rate Significance of learning. CONCLUSIONS: The use of PCNL in the treatment of kidney stones in obese patients achieves similar safety and efficacy as normal-weight patients.
