It has higher sensitivity (> 94%) and specificity (> 95%) than plain radiography ultrasonography and intravenous pyelography 1. Noncontrast computed tomography (NCCT) is widely accepted for diagnosing urolithiasis. We believe that HU/CSA could be used for determining stone treatment plans and predicting outcomes. Multivariate logistic regression analysis revealed that pelvis, ureteropelvic junction stones, and HU/CSA were independent predictors of SFR. There were no significant differences in age, sex, BMI, ASA class, laterality, pre-op shockwave lithotripsy, stone size, stone burden, skin-to-stone distance, and HU between the stone-free and remnant groups. ![]() ![]() Altogether, 188 out of 683 patients met the inclusion criteria. We analyzed HU-related variables using logistic regression model for outcomes. HU and cross-sectional area (CSA) were measured using the free-draw technique. Stone-free status was defined as residual stone measuring ≤ 2 mm within 3 months postoperatively. Preoperative computerized tomography (CT) and follow-up CT within at least 3 months after PCNL were included in this analysis. Demographics and stone characteristics were retrospectively reviewed. We enrolled patients with single renal stones (1–3 cm) who underwent single-tract PCNL between January 2014 and October 2019. We aimed to identify the association between Hounsfield Unit(HU)-related variables and percutaneous nephrolithotomy (PCNL) outcomes. ![]()
