Methods There were 8 patients undergoing micro-PCNL with the new device from June 2016 to February 2017. Values of basic demographic data ,operation time ,pain score ,drop in hemoglobin and complications were recorded. Results The mean stone size,operation time,pain score,drop in hemoglobin,and in-hospital time was(21.9 ± 7.3)mm,(43.6 ± 13.6)min,2.8 ± 1.3,7.0 g/L[(133.2 ± 10.3 g/L vs.(123.2 ± 13.9)g/L,P>0.05]and(3.1 ± 1.0)d,respectively. No patient required blood transfusion. Stone-free rate at 1 and 3 months post-operation were 87.5%(7/8)and 100%(8/8),respectively.
