This diary is used to keep track of things like the kind and amount of liquids you drink, trips to bathroom, etc. Your health care provider may also ask you to keep a bladder diary in order to help with a diagnosis. You'll be asked about your symptoms and health history. You and your health care provider will want to learn the cause of your nocturia. Often, several of these issues may be going on at once. Nocturnal polyuria (when your body produces too much urine at night for your bladder to hold).Edema in the lower limbs, or leg swelling.


This pushes urine out of the bladder and through the urethra. Once you are ready to urinate, the brain sends a signal to the bladder. It is kept closed with sphincter muscles. The urethra is a tube that carries urine from the bladder, out of the body.

The muscular neck (end) of the bladder stays closed to store urine. The muscles in the lower part of the pelvis hold the bladder in place. The brain and the bladder work together to control urinary function. The bladder holds urine until you are ready to empty it. Urine travels from the kidneys to the bladder through the ureters (the tubes that join them). Normally, the kidneys make about 1½ to 2 quarts of urine each day in an adult less in children. Urine forms when the kidneys clean your blood. The "urinary tract" includes the organs in your body that make, store and remove urine.
