Total size of bladder

Urine enters the bladder via the ureters and exits via the urethra. Typically the bladder can hold 300 and 500 ml of urine comfortably for two to five hours. The bladder can be stretched considerably larger and bladder volumes as large as 6000ml have been reported in literature (idiopathic giant bladder). Normally the bladder needs to be emptied 6-8 times (250-500ml of urine each time) during a 24-hour period. Usually the urinating frequency is lower during the night. In cases where the urge to empty the bladder interferes with sleep you might suffer from a condition called nocturia.When a person gets older bladder and urethral functions deteriorate. These changes might lead to more frequent bathroom visits. The bladder capacity itself rarely decreases during aging.
