I'm in medical school, and they very much still do digital rectal exams.  They just brought in a team of people to teach my class how to do it.  It's a screening tool, not a diagnostic tool.  If something doesn't feel right then a more specific test or imaging is done.

It also checks for rectal polyps in addition to feeling for the prostate.
