Abstract：Objective:To investigate the curative effect and safety of percutaneous nephroscopic dual probe ul-trasonic intracorporeal lithotriptor in complex upper urinary tract stones.Methods:The clinical data of 263 pa-tients with complex upper urinary tract stones treated with percutaneous nephroscopic dual probe ultrasonic intra-corporeal lithotriptor (Cyberwand)in our hospital from May 2012 to April 2015 were reviewed retrospectively,in-cluding 159 males,and104 females.There were 107 cases of renal staghorn calculi,89 cases of multiple renal cal-culi,and 67 cases of renal with upper ureteral calculi.Results:262 cases were successfully operated,and only one case failed to establish renal access and was converted to open operation because of floating kidney.2 1 1 patients got stone clearance in stage one,and stone clearance rate of stage one was 80.23% (211/263),31 patients got stone clearance instage two,and the total stone clearrance rate was 92.02 (242/263),Twenty-one patients were given ESWL for residual stones.Postoperative pyemia in 3 cases was cured by strenthening anti-infection,and bleeding was controled in 6 patients by superselective embolization.No case suffered from serious complications,such as perforation of kidney,pneumothorax,inj ury to intestines and so on.Conclusions:The dual probe ultrasonic intra-corporeal lithotripter device is a safe and efficient tool,with special advantages in increasing the stone-free rate, cutting down extravasation of irrigation fluid,and decreasing renal intrapelvic pressure and absorption of bacterio-toxin,which can effectivelly decrease the incidence of complications and improve operation safety.
