Bladder Capacity

There are three bladder capacities. Functional capacity is the average volume of urine voided during the day. The ICS recommends use of a voiding diary to measure functional capacity. Anatomical capacity is obtained during endoscopic examination with the patient sedated or under anesthesia. Cystometric capacity is a combination of patient report and clinician judgment during a cystometric study, and is the volume at which a patient who has normal sensation feels that they can no longer delay micturition. In absence of sensation, cystometric capacity is the volume at which the clinician decides to terminate filling. Adult cystometric capacity should be 300 to 600 mL. Women have larger bladder capacity than men. Bladder capacity in children is calculated by the equations, Cap (mL) = (age in years + 2) x 30, or Cap (mL) = 30 mL + 30 mL x age in years.9 An enlarged bladder capacity is seen in patients with chronic distention and sensory or motor impairment. Small capacity may be found in patients who have sensory urgency, unstable detrusor contractions, infection or inflammation, or after bladder surgery or radiation, and is related to low compliance.
