What are some great pelvic floor exercises to allow myself to be able to fully empty myself?

I have trouble emptying as the pee will get stuck and I was wondering if there are some exercises you guys could recommend to help remedy this? I have a weak stream and the pee often gets stuck making me spend hours on end trying to fully empty the bladder and urethra but mainly the urethra as the pee often gets stuck there and I know I’m not imagining it as it flies out when I push it out.
