Özet
This study claims to examine the relationship between the Housfield unit (HU) value and the success of Electro Shock Wave Lithotripsy (ESWL) treatment. Data of 142 patients were evaluated retrospectively in this cross-sectional observational study. The threshold value for stone density is calculated as 991.20 HU in the ROC analysis. The patients are seperated into two groups with respect to this value, and their demographic characteristics, stone characteristics and success rates after ESWL treatment are statistically compared. For the variables that are statistically crucial in the univariate analysis, logistic regression analysis are used as a multivariate analysis. The mean age of all patients were 45.25±11.72 years and the mean body mass index (BMI) is 28.42±3.98 kg/m2. While our stone-free rate was 66.2% in our study, the mean stone size was 11.25±3.83mm, the Hounsfield unit value was 1007.55±337.75 HU, and the stone-skin distance was 108.02±20.02mm, respectively. We observed a crucial difference in between the Housfield unit value and stone size in univariate and multivariate analyzes between the two groups, and the stone-free rate after ESWL. The Hounsfield unit value, measured by the non-contrast computed tomography method, is a parameter for the prediction in success of patients undergoing Electro Shock Wave Lithotripsy treatment. Also, stone density above 991.20 HU in patients having urinary system stone disease requires the evaluation of alternative treatments as a condition that reduces the success of the treatment.
