flaccid bladder
Học thuậtThân thiện
Definition
Noun: A medical condition characterized by a urinary bladder that is unable to contract properly to expel urine. This results from damage to the nerves that control bladder function, leading to a loss of sensation, overfilling, and an inability to urinate voluntarily.
Usage
The term "flaccid bladder" is used specifically in medical contexts to describe a type of neurogenic bladder dysfunction. - It is a clinical diagnosis. - It describes the state of the bladder muscle (detrusor) being limp and underactive.
Examples

- Management of a flaccid bladder often requires scheduled catheterization.
