I always have to "go" several times during the night (this is a female thing common in us old ladies). I have found that using electrolyte powder (Hydralite in my case) in my drinking water during the day seems to help. The electrolyte solution appears to stay in my body and hydrate my tissues instead of just going through from one end to the other as appears to happen with plain water. I feel less thirsty and don't have to "go" as often.

Cranberry extract capsules seem to help me, too, as a preventive for bladder irritation/infection, to which I'm prone.

Nothing scientific here, but it might be worth a try.
