Not really advice so much as what I've read over time. Although kegels absolutely help a lot of folks, myself included. Sometimes, according to reading I've done, it comes down to how much, if any, damage is done around the prostatic apex during the surgery.

Here's one article that gives a quick explanation of some research done in this regard.

" Injury to these nerves may explain several features of post-prostatectomy urinary incontinence."

There are links to other articles there which may have more information, possibly there'll be some info there folks can use.
