经皮肾镜取石术(mini-percutaneous nephrostomy,PCNL)是治疗复杂性肾结石的主要方法,出血是PCNL中最常见、最严重的并发症之一。尽管大多数出血可以保守治疗,仍有约0.8%的患者需要借助血管栓塞来控制严重的出血。作者运用单变量分析、前进法多变量回归及相关性分析方法对193例PCNL患者作了一个回顾性分析,术前分析因素包括患者年龄、性别、有无高血压、糖尿病及泌尿系感染、血清肌酐水平、既往同侧结石治疗史、结石边缘、类型及表面积、受累肾脏功能、肾实质厚度及肾积水程度;术中分析因素包括穿刺的肾盏、经皮通道扩张方式、通道大小及数目、术中并发症及手术时间;术
Mini-percutaneous nephrostomy (PCNL) is the main method for the treatment of complex renal calculi. Bleeding is one of the most common and serious complications in PCNL. Although most bleeding is conservative, about 0.8% of patients still require blood vessel embolization to control severe bleeding. The authors used univariate analysis, multivariate regression analysis and correlation analysis to make a retrospective analysis of 193 PCNL patients. Preoperative analysis of factors including age, gender, hypertension, diabetes and urinary tract infection, serum Creatinine level, previous history of ipsilateral stone treatment, type of stone edge, type and surface area, involvement of renal function, renal parenchymal thickness, and hydronephrosis; intraoperative analysis of factors including puncture of the calyces, percutaneous channel expansion, channel size and number Intraoperative complications and operation time; surgery
