ABSTRACT
Objective To investigate the clinical value of ureteroscopy combined with ESWL for the treatment of ureteral stone.Methods From October 2005 to June 2007,a total of 256 patients with ureteral stones were treated in our hospital.The calculus in the middle and lower ureter were removed by ureteroscopy,while the stones in the upper ureter was treated by ESWL.For the cases that failed ureteroscopy or those who had residual stones after the treatment,ESWL was performed as a supplement.ResultsIn the patients with lower ureteral stones,the one-stage cure rate was 98.2%(167/170),while in those with middle and upper ureteral calculi,the rate was 89.2%(50/56) and 73.3%(22/30) respectively.Three patients developed perforation of the ureter during the surgery,and one had mucosal injury of the ureter.One case was converted to open surgery because of perforation of the ureter resulted from ureteral twist.Twelve patients were failed ureteroscopy or had residual stones,and received ESWL as the second-stage treatment,11(91.7%) of them were cured afterwards.Conclusions Ureteroscopy is effective for middle and lower ureteral stones.For the cases failed the operation or have residual calculi,ESWL is a good choice.
