Impacted ureteral stones present unique anatomical characteristics and surgical complexities, making them a significant factor in post-operative ureteral stricture following stone removal.Effective preoperative diagnosis can help avoid or reduce complications associated with impacted ureteral stones and facilitate targeted treatment selection.Non-contrast computed tomography (NCCT) has emerged as the gold standard for diagnosing impacted ureteral stones due to its high sensitivity and specificity.Several studies have demonstrated that indicators derived from NCCT, such as stone volume and size, the extent and area of hydronephrosis, ureteral wall thickness, ureteral wall area, diameter ratios of the ureter segments above and below the stone, and CT value ratios, possess strong prognosis capabilities for impacted stones.This paper reviews the relevant literature to summarize NCCT-based predictive methods, models, and scoring systems for impacted ureteral stones, aiming to provide reference for clinical practice.
