目的观察微通道和标准通道在经皮肾取石术中的应用效果。方法选择2007年6月-2011年5月在我院治疗的肾结石患者124例为研究对象,随机分为A组(微通道组)63例、B组(标准通道组)61例,观察两种通道在在经皮肾取石术中的应用效果。结果 A组Ⅰ期碎石成功率73.0%,明显低于B组;平均手术时间91.7±28.4min,明显长于B组;术后患者发热率19.0%,明显高于B组;以上P均<0.05。结石清除率87.3%、平均住院时间7.5±3.2d、术后出血≥800ml的患者比例为3.2%,与B组比较,差异不明显,以上P均>0.05。结论与微通道经皮肾取石术相比,标准通道经皮肾取石术能够缩短手术时间、降低术后发热率、提高Ⅰ期碎石成功率,同时不增加住院时间及出血量。
Objective To observe the application of microchannels and standard channels in percutaneous nephrolithotomy. Methods A total of 124 patients with renal stones treated in our hospital from June 2007 to May 2011 were selected and randomly divided into group A (micro-channel group), 63 cases, group B (standard channel group), and observation group two The application effect of kinds of channels in percutaneous nephrolithotomy. Results The success rate of grade Ⅰ gravel in group A was 73.0%, which was significantly lower than that in group B. The average operation time was 91.7 ± 28.4min, significantly longer than that in group B. The postoperative fever rate was 19.0% . The stone clearance rate was 87.3%, the average hospitalization time was 7.5 ± 3.2 days, and the postoperative bleeding ≥800ml was 3.2%. There was no significant difference between the two groups (P> 0.05). Conclusion Compared with the mini-percutaneous nephrolithotomy, standard percutaneous nephrolithotomy can shorten the operation time, reduce the postoperative fever rate, and improve the success rate of stage Ⅰ gravel without increasing the length of hospital stay and bleeding.
