A Donna Hill Howes, RN, Family Medicine, answered. A healthy adult bladder can hold between 350 milliliters (ml) and 550 ml of urine, which is about one and a half to two cups.
This is called the post-void residual. The bladder has a approximately 500ml capacity. You should feel a desire to void at ~250ml. Urinary retention is measured by using a special type of ultrasound (bladder scan), or by inserting a bladder catheter and measuring how much urine comes out. I'm a 4th year US med student. On one of my urology rotation I asked the Sr. resident this exact question.
