The urinary bladder is a hollow muscular sac that holds urine.
Location
The urinary bladder is located in the lower pelvis and is infraperitoneal (under the peritoneum), posterior to the pubic symphysis.
- The urinary bladder lies on the pubic bones, fascia of the levator ani and superior part of obturator internus.
- Between the pubic symphysis and bladder there's a potential space known as the retropubic space (or cave of Retzius).
- In children and infants, the bladder is in the abdomen even when empty.
