Similarly, hematological markers of inflammation, such as C-reactive protein (CRP) levels and neutrophil-to-lymphocyte ratio (NLR), have been proposed as indicators of ureteral obstruction and inflammatory response, which may influence stone expulsion dynamics [8]. CRP and NLR are used as markers for predicting MET success due to their roles in reflecting the inflammatory status and systemic response to ureteral stones. Here, CRP is linked to Ureteral obstruction.
