HL lithotripsy is now considered the gold standard treatment for ureteral stones but success seems to be related to stone anatomical site, size and hardness, which are intrinsic stone factors. These factors may interfere with operative time and the risk of ureteral wall injury with the subsequent need for ureteral stenting. El-Nahas et al reported their experience with 841 patients with a mean age of 48.5 years in whom ureteral calculi were treated with ureteroscopy (reference 7 in article). The complication rate was 6.7% and the stone-free rate after 1 ureteroscopic intervention was 87%.
