Do Kegal exercises counter perineal mages?

I am pregnant with my first child and I want to avoid an episiotomy and minimize tearing. I have been advised to do perineal mages to reduce the chances of either of the prior, however I feel t is most effective to keep my urinary tract strong by doing kegal exercises to avoid leakage. I am wondering if the kegal exercise counters the perineal mage to make either ineffective?
