1840 THE EFFECT OF COMBINED FUROSEMIDE AND INTRAVENOUS HYDRATION TO ESWL SUCCESS ON RENAL STONES

session (82.6%) (p 0.004). After correcting for stone size and location, fluoroscopy time (p 0.001), fragmentation rate (p 0.002), and stonefree rate (p 0.04) maintained their significance. When comparing the top 3 RTs performing 100 SWL sessions, RTs B and C had significantly higher fluoroscopy time compared with RT A [OR (95%CI): 1.84(1.382.45); p 0.001 and 2.67 (2.003.57); p 0.001], respectively. After correcting for stone size and location, RT B had significantly lower fragmentation rate when compared with RT A [OR (95%CI): 0.21(0.05-0.86), p 0.03]. However, there were no significant differences among the top 3 RTs in terms of stone-free rates. CONCLUSIONS: RTs significantly differ in fluoroscopy usage in addition to stone fragmentation and stone-free rates.
