Abstract:
Objective To evaluate the efficacy and safety of holmium laser lithotripsy for the treatment of urinary calculi.Methods A total of 1216 cases of urinary calculi underwent ureteropyeloscopic and cyctocopic holmium laser lithotripsy.There were 1 006 cases of ureteral stones(302 cases of upper ureteral stones,364 cases of middle ureteral stones,and 340 cases of lower ureteral stones) and 210 cases of bladder stones.Results In 1 case of upper ureteral stones,failure to access the ureteral orifice due to enlarged prostate was encountered,and extracorporeal shock wave lithotripsy(ESWL) was employed.In 1006 cases of ureteral stones,the rate of successful fragmentation on single session was 95.5%(961/1 006),with 89.4%(270/302),96.4%(351/364),and 100%(340/340) for upper,middle,and lower ureteral stones,respectively.Ureteral perforation was encountered during lithotripsy in 6 cases.In 210 cases of bladder stones,the rate of successful fragmentation on one session was 100%(210/210).No bleeding or bladder perforation was observed during lithotripsy.Follow-up checkups for 0.5~40 months(mean,18.6 months) in 881 cases of ureteral stones showed that the stone-free rates were 91.1%(224/246),98.5%(318/323),and 100%(312/312) for upper,middle,and lower ureteral stones,respectively.The overall stone-free rate for all levels of ureteral stones achieved 96.9%((854/881)).Ureteral stenosis was found in 6 cases.Follow-up checkups for 0.5~31 months(mean,12.4 months) in 187 cases of bladder stones revealed a stone-free rate of 98.4%(184/187). Conclusions Holmium laser lithotripsy is a highly effective,minimally invasive,and safe therapy for urinary calculi.It is indicated as the first choice of treatment for patients with ureteral stones and bladder stones.
