【摘要】 目的:探讨微通道经皮肾镜取石术(MPNL)治疗肾下盏结石的方法、疗效,以及适应证的选择。方法:采用MPNL治疗肾下盏结石79例,结石大小为10~31mm,平均(19.0±4.6)mm。在X线或B超引导下,采用分步或一期手术行MPNL弹道碎石或钬激光碎石取石。结果:73例一次手术取净结石(取净率92.4%),4例两次手术后取净结石,总无石率97.5%。手术时间22~96min,平均(38±13)min。无输血,无严重并发症发生。结论:MPNL是治疗肾下盏结石的一种疗效好、安全性高的手术方法;对于直径大于10mm,特别是直径>20mm的肾下盏结石,MPNL可作为首选的治疗方法。更多还原

【Abstract】 Objective:To investigate the methods, effectiveness and the choice of indications of minimally channel percutaneous nephrolithotomy (MPNL) for lower calyceal calculi.Methods:Seventy nine cases of patients with lower calyceal calculi underwent minimally invasive percutaneous nephrolithotomy (MPNL), the size of stones ranged from 10 to 31mm, mean (19±4.6) mm. Under X ray or ultrasound guidance, stones were crashed with pneumatic ballistic or holmium laser lithotripsy devices in a II stages or single stage.Results:Stones were cleaned in 73 cases in single stage (clearance rate 92.4%), 4 cases achieved clear by two procedures, the whole stone clearance rate was 97.5%. Operating time was 22 to 96min, mean (38±13) min. In this group, no blood transfusion was needed, no severe complication occurred.Conclusions:For the stones≥10 mm, especial lower pole kidney stones >20 mm, MPNL would be considered as the principal treatment.更多还原
