Why does anesthesia causes bladder distention?

Anesthesia can cause bladder distention primarily due to the relaxation of the bladder muscles and the inhibition of normal bladder reflexes. General anesthesia often leads to decreased neural control and reduced awareness of the need to urinate, which can result in urinary retention. Additionally, certain anesthetic agents and procedures may temporarily impair the bladder's ability to contract effectively. As a result, urine accumulates, leading to distention.
