Questions about the relationship between benign prostatic hyperplasia and nocturia

I've been taking medication for benign prostatic hyperplasia for three years. My doctor hasn't suggested surgery, and I only get an ultrasound once a year. I think he's trying to determine if cancer has metastasized.

At first, the effect of the drug was immediate, but now, even if the dosage is increased, the effect does not come right away, so I asked the doctor to increase the dosage last time, but he said that increasing the dosage is not necessarily a good thing, so I kept the dosage the same and it has been 2 years since then. Looking at the trend, if I fall asleep at 10 PM, I wake up about 3 times until 5 AM, and if I fall asleep at 11 PM, I can sleep until 5 AM without waking up.

The question here is, does an enlarged prostate cause you to wake up when you need to urinate, regardless of the nocturnal enuresis? When I was young, I had a hard time because of the nocturnal enuresis since I was in the second grade of elementary school. I am afraid that I will have this problem even when I get older, so I am hesitant to go out and ask anyone. It is embarrassing to ask anyone, and if an enlarged prostate has nothing to do with nocturnal enuresis, it would be comfortable and I could go out and do it...
