RESUMO
Objective To evaluate the clinical value of a new optic puncture needle designed by our department for renal calculi treatment. 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. One suffered urinary tract infections( ClavienⅠ)and was treated with antibiotics. There were no major complications. Conclusion The new device for treatment of renal calculi is feasible and effective.
