Popis:	Abstract We aimed to evaluate the correlation between endoscopic papillary abnormalities (PA) and high renal papilla Hounsfield density (PHD) on CT scan in patients who underwent flexible ureteroscopic treatment (fURS) for renal stones. We retrospectively assessed patients from a prospectively collected database who were treated with fURS for renal stones between May 2016 and October 2020. PHD was measured on preoperative CT-scan by a radiologist blinded from the intraoperative aspect of the papillae. Correlation was examined between high PHD (≥ 43 HU) and PA described in fURS, stone composition, metabolic abnormalities, … Out of 159 consecutive cases, 131 were eligible for analysis with available preoperative CT-scan. Median age was 55 years (IQR 43–67) and median PHD was 40 (IQR 36–45). Eighty patients (61%) had PHD
