Abstract: Objective To evaluate the clinical effects of block calculus extraction catheter in the ureteroscopic lasertripsy. Methods Two hundred and thirty patients with ureter calculus were enrolled. Ninety-six patients were treated with block calculus extraction catheter (test group), and 134 patients were treated without block calculus extraction catheter (control group). The patients in 2 groups were treated with holmium laser ureteroscopic lithotripsy of Lumenis PowerSuite60W, and the treatment effectiveness was compared. Results The operation time and primary stone clearance rate in test group were significantly better than those in control group: (23.3 ± 7.4) min vs. (35.6 ± 11.1) min, 98.92%(92/93) vs. 88.89%(112/126), and there were significantly differences (P<0.01). The bleeding amounts and fever rate of 2 groups had no significant difference (P > 0.05). Conclusions The block calculus extraction catheter is very useful and safe in preventing the calculus shift, shortening the operation time and improving the calculus elimination rate .
