To compare the mean operative time (MOT) in patients undergoing Ho: YAG laser lithotripsy (LL) and pneumatic lithotripsy (PL) for ureteric stones.
This randomized study was conducted at Armed Forces Institute of Urology (AFIU) Rawalpindi, Pakistan from July 2016 to November 2018. Non probability consecutive sampling technique utilized to enroll 60 patients of both gender aged 18-60 years, having ureteric calculus ≤1.5cm. Randomization was done into group I (LL) and II (PL) via computer generated number tables. Six Consultant Urologists performed surgeries under spinal anesthesia utilizing Swiss Lithoclast Master (EMS S.A. Switzerland) in group II and holmium laser fiber (365μm, 8-10Hz, 9.6-16W, 2100nm wavelength) in group I respectively. MOT was noted from insertion of cystoscope till removal out of meatus. Data obtained was analyzed through IBM SPSS 24.0.
Analysis involved 60 patients (30 each group) having similar baseline characteristics (age, gender, laterality, location). There was statistically significant different MOT between LL & PL (25.48±6.99 vs 34.83± 7.47 minutes, p < 0.001). Data stratification with respect to age, gender, laterality and stone location revealed similar trend. Lithotripsy technique significantly affected MOT (p < 0.001) on Multiple Linear Regression Analysis.
Ho: YAG LL is an efficient technique when compared with PL in terms of MOT for ureteric stones.
比较接受钬激光碎石术（LL）和气压弹道碎石术（PL）治疗输尿管结石患者的平均手术时间（MOT）。
本随机研究于2016年7月至2018年11月在巴基斯坦拉瓦尔品第武装部队泌尿外科研究所（AFIU）进行。采用非概率连续抽样技术纳入60例年龄在18 - 60岁、输尿管结石≤1.5cm的男女患者。通过计算机生成的数字表将患者随机分为I组（LL）和II组（PL）。6位泌尿外科顾问医生分别在脊髓麻醉下进行手术，II组使用瑞士Lithoclast Master（瑞士EMS S.A.公司），I组使用钬激光光纤（365μm，8 - 10Hz，9.6 - 16W，波长2100nm）。记录从插入膀胱镜到尿道口拔出的MOT。所获数据通过IBM SPSS 24.0进行分析。
分析涉及60例患者（每组30例），他们具有相似的基线特征（年龄、性别、患侧、结石位置）。LL组和PL组之间的MOT存在统计学显著差异（25.48±6.99分钟 vs 34.83±7.47分钟，p < 0.001）。按年龄、性别、患侧和结石位置进行数据分层显示出相似趋势。在多元线性回归分析中，碎石技术对MOT有显著影响（p < 0.001）。
在输尿管结石的MOT方面，与PL相比，钬激光碎石术是一种有效的技术。
