电子输尿管软镜与微创经皮肾镜碎石术治疗肾结石的比较

Comparison of digital flexible ureteroscopic lithotripsy and minimally invasive percutaneous nephrolithotomy for renal calculi

目的:比较电子输尿管软镜与微创经皮肾镜碎石术治疗肾结石的疗效和安全性。方法:回顾性分析我院接受手术治疗105例肾结石患者,其中电子输尿管软镜碎石术(A组)53例,微创经皮肾镜碎石术(B组)52例,比较两种方法在手术时间、术中出血量、结石清除率、并发症、平均住院时间上的差异。结果 :A、B组在年龄、性别、结石直径、结石表面积、手术时间、结石清除率、并发症上没有明显的差异。A、B组在术中出血、平均住院时间上具有差异性。结论:电子输尿管软镜碎石术治疗20 mm左右肾结石在手术时间、结石清除率、并发症发生率上与微创经皮肾镜碎石术相当,但在术中出血、平均住院日上优于微创经皮肾镜碎石术,可以作为20 mm左右肾结石治疗的首选。

Objective To compare the effect and safety of digital flexible ureteroscopic lithotripsy and per- cutaneous nephrolithotomy for renal calculi. Methods Clinic data of 105 cases with kidney stones were analyzed retrospectively, including 53 cases with digital flexible ureteroscopic lithotripsy （group A） and 52 with minimally invasive pereutaneous nephrolithotomy （group B）. The operative time, intraoperative blood loss, stone-free rate, complications, average hospitalization time were compared. Results There were no significant differences in age, gender, stone size, stone surface area, average operative time, stone-free rate and complications between two groups. Significant differences were found between group A and group B in terms of intraoperative blood loss and average hospitalization time. Conclusions Digital flexible ureteroscopic lithotripsy has similar effect as minimally invasive percutaneous nephrolithotomy for the treatment of kidney stones about 20 mm in terms of average operative time, stone-free rate, and complications, but excels minimally invasive percutaneous nephrolithotomy in intraopera- tive blood loss and average hospitalization time. Digital flexible ureteroscopic lithotripsy can be the first choice for the treatment of kidney stones about 20 mm.
