detrusor areflexia
Pronunciation: dee-TROO-zor ay-ree-FLEX-ee-ah
Complete absence of detrusor muscle contractions during bladder filling or voiding attempts.
Full Definition
Detrusor areflexia is a urodynamic diagnosis characterized by the complete absence of detrusor muscle contractions during bladder filling and voiding phases. This condition results in impaired or absent voluntary voiding, often requiring catheterization for bladder emptying. Detrusor areflexia commonly occurs following spinal cord injuries, particularly those affecting the sacral segments, or may result from peripheral nerve damage. The condition is diagnosed through urodynamic studies and represents the most severe form of detrusor underactivity.
Usage
Usage note: Distinguish from detrusor underactivity, which implies some residual function.
