摘要: Purpose: Extracorporeal Shock Wave Lithotripsy (ESWL) has shown successful outcomes for ureteral stones. We investigated predictive factors failure of ESWL treating Materials and Methods: A total 153 patients who underwent between July 2006 2009 stones diagnosed by non-enhanced spiral computed tomography were divided into two groups: (group A, stone size ≤10 mm; group B, >10 mm). The was defined as remnant >4 mm. assessed age, sex, body mass index, size, laterality, location, skin-to-stone distance (SSD), Hounsfield unit, the presence secondary signs (hydronephrosis, renal enlargement, perinephric fat stranding, tissue rim sign). analyzed using logistic regression in each group. Results: success rates 90.2% 68.6% respectively. In univariate analysis group, SSD, all showed statistically significant differences terms outcome (p<0.05). multivariate regression, (odds ratio [OR], 50.005; 95% confidence interval [CI], 6.207 to 402.852) an independent factor A. standing (OR, 77.634; CI, 1.349 446.558) 19.718; 1.600 243.005) B.
