When I had stranguria, I got a sitz bath basin that sits on the toilet seat and filled it with hot water. As soon as I immersed my butt and my junk, the urine came pouring out. It was how I avoided needing a catheter. Heard about this tip from a nurse who helped pregnant women deal with urine retention.
Ever notice how when you're in hot water you have the urge to pee? It's basically that idea.
Not really convenient I guess for every single time you need to pee, but maybe for the times when it's acting up and particularly bad.
Or maybe you could use a lower tech version like a hot cloth on your abdomen above your bladder every time you need to go. There's something about sudden heat in the bladder region that makes the urine pressure go up.
If it's your prostate though that's going to be hormone related. Usually too much estrogen. Taking an aromatase inhibitor can help but only if it's the prostate and only if they have first ruled out infection.
