Waking up several times a night to urinate is called nocturia.

Nocturia

Normally, urine decreases in amount and become more concentrated at night. That means, most people can sleep 6 to 8 hours without having to urinate.

But, persons with nocturia get up more than once during the night to urinate. Because of this, those who have excessive urination at night often have disrupted sleep cycles.
