Title: Treatment of proximal ureteral calculi with ureteroscopic holmium:YAG laser lithotripsy:Report of 205 cases
Abstract: Objective To assess the efficacy and safety of ureteroscopy with holmium:yttrium-aluminium-garnet(Ho:YAG) laser lithotripsy for proximal ureteral stones.Methods A series of 205 patients with proximal ureteral calculi were treated with rigid ureteroscopy combined with Ho:YAG laser lithotripsy from May 2005.Stones ranged in size from 0.8-1.4 cm.Results The initial stone-free rate in all patients achieved 93.7%(192/205) in our procedure except for thirteen residual stones.Some residual fragment(4-6 mm) were in the kidney or the ureter in nine cases of those,and four ureteral stones were migrated into the renal pelvis and calices during the procedure.One removal stone was underwent by percutaneous lithotripsy(PCNL) and the other three were treated with extracorporeal shock wave lithotripsy(ESWL).Stone fragmentation or removal calculi were accomplished.There were no major complications such as ureteral perforationin or segmentation in all procedures.No laser-related complications occured.The meaning hospital stay time was 3.5 d(3-9 d).Residual stones were evaluated at first week to third months after the procedure.Our data shows high stone-free rates(93.7%) with a low complication rate(4.5%) during 3-24 months'(mean 6 mon) follow-up.Conclusions The Ho:YAG laser is an ideal and reliable intracorporeal lithotripter and highly effective and safe treatment for proximal ureteral calculi with a high success rate and low morbidity.
