不同体质指数对经皮肾镜碎石术的影响研究

Impact of Different Body Mass Index Levels on Patients Undergoing Percutaneous Nephrolithotomy

目的观察不同体质指数对经皮肾镜碎石术的影响。方法选择ASA1—3级行经皮肾镜碎石术患者106例。其中体质指数〈18．5ks／m2患者29例为A组，18．5ks／m2≤体质指数〈24．0kg／m2患者40例为B组，体质指数≥24．0kg／m2患者37例为C组，比较三组患者结石清除率、输血例数、术后平均住院时间及并发症发生率。结果三组术后结石清除率、输血例数、术后平均住院时间比较，差异无统计学意义（P〉0．05）；A组术后并发症发生率高于B和C组，差异均有统计学意义（P〈0．05）；B、C两组并发症发生率比较，差异无统计学意义（P〉0．05）。结论低体质指数患者手术耐受性较差，应密切监测患者生命体征，尽量缩短手术时间，以避免严重并发症的发生。

Objective To observe the impact of different levels of body mass index on patients undergoing percutane- ous nephrolithotomy. Methods A total of 106 surgical patients （ASA 1 - 3） underwent percutaneous nephrolithotomy were en- rolled. All patients were divided into three groups： group A included 29 patients with body mass indices less than 18. 5 kg/m2 , group B included 40 patients with body mass indices between 18.5 kg/m2 and 24. 0 kg/m2, and group C included 37 patients with body mass indices more than 24.0 kg/m2. Stone clearance rates, numbers of the blood transfusion cases, mean postoperative hospital stay and complication rates were compared among the three groups. Results No significant differences were observed in stone clearance rate, number of blood transfusion cases and mean postoperative hospital stay among the three groups （P 〈 0. 05）. Complication rate in group A was higher than in the other two groups （ P 〈 0. 05 ）, but no significant differences were noted in incidence rates of complications between group B and group C （ P 〉 0. 05） . Conclusion Patients of lower body mass indices are less tolerant to perecutaneous nephrolithotomy. These patients should be closely monitored for vital signs during the op- eration, with shorter operation time preferred, to avoid serious complications.
