Hi
Follow up with your doctor. Are you off the medication now? Some people end up on the medication for a long time.
I agree with zigemyster.....see a urologist if you are ask him/her about doing a urine test, scans, a cystoscopy (which looks into the bladder and they can go further up and check out the kidneys).
They do make Depends or Poise for men, I know it's not something you want either as zigemyster said but for now it might be the best option until you see your doctor.
I don't know if the kegal exercise work men (I found articles online and it says it does help). Here's a link: (you might want to try this as well)

It's still important to follow up with your doctor.
Keep us posted....All the Best.
