目的:探讨输尿管软镜治疗>2cm孤立肾结石的临床疗效。方法:回顾性分析我院2011年2月~2015年2月应用输尿管营软镜治疗12例孤立肾结石患者临床资料,分析结石清除率及血清肌酐值的变化。结果:12例患者结石直径为2.1~4.0cm,平均2.6cm手术时间为60~240min,平均109min;12例患者中9例(75%)一期手术将结石全部击碎;2例接受二期输尿管软镜手术治疗,二期手术结石清除率为91.6%;术前血清肌酐值为67~247μmol/L,平均(77.3±32.1)μmol/L,术后第1天复查血清肌酐值为88~265μmol/L,平均(90.4±27.2)μmol/L,术后1个月复查血清肌酐值为56~164μmol/L,平均(76.5±24.4)μmol/L,与术前比较差异有统计学意义(P<0.05)。结论:输尿管软镜治疗>2cm孤立肾结石安全有效,值得推广应用。
Objective: To investigate the clinical efficacy of ureteroscopic soft lens in treatment of> 2cm isolated kidney stones. Methods: The clinical data of 12 patients with solitary renal calculus treated with ureteral soft-lens in our hospital from February 2011 to February 2015 were retrospectively analyzed. The changes of stone clearance and serum creatinine were analyzed. Results: In 12 patients, the diameter of stones was 2.1-4.0cm and the average 2.6cm operation time was 60-240min with an average of 109min. Nine of the 12 patients (75% Urease soft-lens surgery, the second operation stone clearance rate was 91.6%; preoperative serum creatinine value 67 ~ 247μmol / L, an average of (77.3 ± 32.1) μmol / L, the first day after the review of serum creatinine value of 88 ~ The average serum creatinine was 56 ~ 164μmol / L at 1 month after operation, with an average of (76.5 ± 24.4) μmol / L, which was significantly different from that before operation (265μmol / L and 90.4 ± 27.2μmol / P <0.05). Conclusions: Ureteral soft-lensing is safe and effective for> 2cm isolated renal calculi, which is worth popularizing and applying.
