Urologists treat a wide range of problems related to the urinary system and the male reproductive organs. This includes conditions affecting the kidneys, bladder, urethra, and ureters in both men and women, as well as issues specific to the male reproductive system. 

Check in with your health care provider if: There's no obvious reason for your frequent urination, such as drinking more total fluids, alcohol or caffeine. The problem disrupts your sleep or everyday activities. You have other urinary problems or symptoms that worry you

It's generally considered normal to urinate once or twice at night. Most people can sleep for six to eight hours without needing to get up to use the bathroom. Waking up more than once a night, or if you feel like you have to urinate frequently at night, might be a sign of nocturia, which is a condition where you have to wake up to urinate more than once at night.
