摘要目的 比较智能控压输尿管软镜吸引取石术与普通电子输尿管软镜碎石术治疗≤2 cm肾结石的效果.方法 回顾性分析2015年6月至2017年12月267例在江西省赣州市人民医院泌尿外科接受输尿管软镜碎石的肾结石患者的临床资料.男性129例,女性138例,年龄51.2岁(范围:19～76岁).145例患者行智能控压输尿管软镜吸引取石术(控压组),122例患者行电子输尿管软镜碎石术(对照组).采用t检验、x2检验或Fisher精确概率检验比较两组患者的寻石成功率、一期结石清除率、并发症发生率、手术时间、术后住院时间等.结果 控压组手术时间短于对照组[(26.2±8.6)min比(47.2±18.4)min,t=1.968,P=0.000],一期结石清除率高于对照组(97.2％比86.0％,x2=0.069,P=0.004),总体并发症发生率低于对照组(2.7％比18.0％,x2=17.586,P=0.000).两组术中寻石成功率(97.2％比95.9％,x2=0.069,P=0.791)、术后住院时间[(1.58±0.54)d比(1.65±0.61)d,t=-0.768,P=0.905]差异均无统计学意义.结论 智能控压输尿管软镜吸引取石术较普通输尿管软镜手术时间短、一期结石清除率高、并发症少.

abstractsObjective To evaluate the effectiveness and safety of intelligent pressure control fl.exible ureteroscope for management of renal stones ≤ 2 cm.Methods The clinical data of 267 cases of renal calculi treated with flexible ureteroscope lithotripsy at Department of Urology,Ganzhou People's Hospital from June 2015 to December 2017 were analyzed retrospectively.There were 129 male and 138 female patients,with a mean age of 51.2 years (ranging from 19 to 76 years).Among them,145 patients underwent intelligent pressure control flexible ureteroscope (intelligent control group) and 122 patients underwent flexible ureteroscope ordinary (ordinary group).The t test,x2 test or Fisher exact test were used for statistical analysis.The success rate of stone seeking,the stone free rates,the incidence of complications,the average operation time,the average hospital stay after operation were compared between the two groups.Results The average mean operative time of the patients with intelligent control group was (26.17 ± 8.64) minutes,significantly shorter than (47.23±18.35) minutes of the ordinary group (t =1.968,P=0.000).The stone free rate of the patients with intelligent control group was 97.2％,it was higher than 86.0％ of ordinary group (x2 =0.069,P=0.004).The complication rate of the patients with intelligent control group was 2.7％,which was significantly shorter than 18.0％ of the ordinary group (x2 =17.586,P=0.000).However,there was no significant difference between the two groups in the success rate of stone seeking and postoperative hospital stay (P＞0.05).Conclusion Intelligent controlled pressure ureteral flexible ureteroscope has the advantages of short operation time,high stone free rate and less complications in the treatment of renal calculi ≤2 cm compared with flexible ureteroscope ordinary.
