It aims to scientifically assess the systemic immuneinflammation index (SII) as a prognostic marker for patient outcomes. While several prior investigations have explored the prognostic value of SII in other urological conditions, our research marks the first venture into its application for UC, rendering this an innovative exploration. Furthermore, our study is registered on the PROSPERO website, boasting a unique registration ID, which further underscores its novelty and originality.
