The detrusor muscle remains relaxed to allow the bladder to store urine, and contracts during urination to release urine. Related are the urethral sphincter muscles which envelop the [[urethra]] to control the flow of urine when they contract. In older adults over 60 years in age, the detrusor muscle may cause issues in voiding the bladder, resulting in uncomfortable [[urinary retention]]. [[Urinary retention]] from [[detrusor muscle]] areflexia or hypotonia ([[autonomic neuropathy]]) from [[diabetes mellitus]]. ---- [[Urinary bladder dysfunction]] due to lesions in the central or peripheral nervous systems. Clinical [[manifestation]]s differ based on the location of the lesion. ● [[detrusor muscle]] hyperreflexia (detrusor overactivity (DO)): involuntary contraction of the detrusor muscle → sensation of urgency & possible urge incontinence ● detrusor-sphincter dyssynergia (DSD): detrusor contraction with inappropriate activation of the external urethral sphincters ● detrusor areflexia: loss of [[bladder]] tone → inability to contract sufficiently for micturition detrusor_muscle.txt Last modified: 2024/06/07 02:52by 127.0.0.1
