see Urinary bladder dysfunction
Urinary bladder dysfunction due to lesions in the central or peripheral nervous systems. Clinical manifestations 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
Elevated Postvoid residual volume can be indicative of several conditions, including urinary retention, neurogenic bladder dysfunction, bladder outlet obstruction (such as in benign prostatic hyperplasia in men), urinary tract infections, and other urinary tract issues.
