ABSTRACT

Objective To summarize the clinical experience of ESWL under B ultrasound guidance in treatment of urinary stones.Methods The clinical data of 20 625 patients who underwent B ultrasound-guided ESWL between August 1995 and July 2011 were retrospectively analyzed.Of the stones,8659cases were in the kidney,11 712 cases were in the ureter,and 254 cases were in the bladder.And 1965stones were radioparent.Results The stone fragmentation rates of the kidney,ureter and bladder stones were 96.27％ ( 8336/8659),97.56％ ( 1 1 426/1 1 712) and 99.21％ ( 252/254),respectively.The total stone fragmentation rate was 97.04％ (20 014/20 625 ).The 3-month stone-free rates of the kidney,ureter and bladder stones were 86.63％ (7501/8659),95.32％ ( 11 164/11 712) and 97.24％ (247/254),respectively.The total 3-month stone-free rate was 91.69％ (18 912/20 625).The stone fragmentation rate of radioparent stones was 97.91％ ( 1924/1965 ),and the 3-month stone-free rate was 94.40％ ( 1855/1965).Conclusion B ultrasound-guided ESWL is safe and effective in the treatment of urinary stones.
