Does rectal examination have any value in the clinical diagnosis of cauda equina syndrome?

Digital rectal examination has no significant value in the acute diagnosis of cauda equina syndrome. This study further confirms that there is no discreet clinical protocol applicable with which to confidently confirm or rule out this diagnosis. DRE is traditionally enshrined as an essential facet of clinical assessment in suspected cauda equina syndrome but it cannot be used as a discriminator to ration urgent MRI scanning.
