Mp22-04 Ureteroscopy for Ureteral Stones: A Multivariate Analysis of Adverse Events

Abstract

The stone free patients and those with residual fragments have similar distribution in age, sex, stone laterality, American Society of Anaesthesiologists score and BMI. Overall stone free rate is 54.8%. Stone-free patients had significantly lower mean Guys's score (2.8 vs 3.3, p¼0.000), lower mean S.T.O.N.E nephrolithometry score (8.0 vs 8.7 p¼0.030) and higher mean CROES normogram score (170.6 vs 153.2 p¼ 0.000).Logistic regression analysis showed that all three scoring systems were significantly associated with stone free status.
