Proximal/Distal ureteral diameter ratio as a predictor of spontaneous passage in <10 mm ureteral stones
Abstract
BACKGROUND: Ureteral stones are a common cause of acute renal colic, and while most small stones pass spontaneously, reliable predictors of passage are needed to optimize patient selection for conservative management. This study aims to evaluate the role of radiologic, clinical and laboratory parameters-particularly the proximal/distal (P/D) ureteral diameter ratio-in predicting spontaneous passage of
