Vladimirsky was carried out. The relationship between preoperative and intraoperative factors and complications of ureterolithotripsy was analyzed. The overall complication rate was 22.4%. The risk of intraoperative complications was proved to increase (p<0.05) along with the stone size, location in proximal ureter, stone impaction for more than 3 weeks and the degree of hydronephrosis. No preoperative stenting or nephrostomy tube prior to ureteroscopy was associated to an increased risk of intraoperative complications (RR=2.88; p=0.03). Patients with preoperative drainage of upper urinary tract has lower probability of intraoperative complications (OR=0.35; p=0.03). The risk of developing stricture and ureteral obliteration in uncomplicated ureteroscopy was mria and intraoperative trauma complications.
