Cauda equina syndrome (CES) is a rare serious condition that, if missed at initial presentation, can lead to serious disability. Early diagnosis is crucial for a favourable outcome. Few studies included urodynamic test and measurement of post-void residual urine (PVR) as an adjunct screening tool for acute CES before proceeding to MRI scan, yet there are differences in the cut-off point as a threshold volume to be considered as a red flag for doing MRI amongst these studies. Meta-analysis and systematic review of literature that included PVR as a predictive tool in CES to identify the reliability of PVR and the optimal numerical value to be considered as red flag.Abstract
