Ureteroscopic holmium laser lithotripsy for managing 252 patients with ureteral calculi

Objective:To evaluate the effectiveness and safety of ureteroscopic holmium:YAG laser lithotripsy for managing ureteral calculi.Methods:Ureteroscopic holmium:YAG laser lithotripsy was used in 252 patients with ureteral calculi(proximal in 36 patients,middle in 86 and distal in 130 patients).Results:The stone-free rate was 88 in the patients with proximal ureteral calculi,91 in those with middle ureteral calculi and 95 in those with distal ureteral calculi respectively.The complications occurreded in 5.9(15/252) during and after the operation.Conclusions:Ureteroscopic holmimium:YAG laser lithotripsy is a highly effective and safe method for managing ureteral calculi.
