Preoperative CT-Derived Stone Burden Metrics for Predicting Stone-Free Status and Operative Time After Retrograde Intrarenal Surgery

Objectives: Non-contrast computed tomography (NCCT) is used before retrograde intrarenal surgery (RIRS) to describe stone size, location, and complexity, but the best way to summarize stone burden remains unsettled. Therefore, we compared multidimensional NCCT-derived burden metr...

Physicochemical indicators and recurrence of urolithiasis in patients with hyperuricemia: a predictive model

Abstract Objective To identify metabolic predictors of urolithiasis recurrence and investigate whether the predictive value of urinary citrate differs across metabolic subgroups, with the aim of developing a subgroup-specific prediction model. Methods We retrospectively analyzed...
