Ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi (A report of 168 cases)

Abstract

The effectiveness and safety of ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi was evaluated. Ureteroscopic holmium: YAG laser lithotripsy was performed in 168 ureteral calculi (upper 27 cases, middle 33 cases and lower 108 cases). The results showed that the stone-free rate was 92.6% in the upper ureteral calculi, 93.9% in the middle ureteral calculi and 94.4% in the lower ureteral calculi, respectively. The complication rate was 4.8% (8 cases). It was suggested that ureteroscopic holmium: YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.
