One more non-medical suggestion. Because my metastasis had left me paraplegic for a while, I'd gotten used to using urinal bottles like these during my months in the hospital:

When my dysuria started and I needed to go every 30 min sometimes at night, I found that keeping one of these beside the bed make a big difference: I didn't need to wake all the way up to use it (no walking to the bathroom, etc), and because I knew it was so close, I ended up needing it less, because I didn't feel as worried about making it (stress can cause the detrusor muscle to contract — search for "urge incontinence"). So my sleep starting improving.

You can keep hand sanitizer on the bedside table to clean your hands, and in the morning, just empty the urinal bottle into the toilet, then shake it up with some water and squirt of hand soap or shampoo to keep it clean and fresh-smelling.
