detrusor overactivity
Involuntary bladder muscle contractions during bladder filling that may cause urgency and incontinence.
Full Definition
Detrusor overactivity refers to involuntary contractions of the detrusor muscle during the filling phase of the bladder cycle, as demonstrated on urodynamic studies. In pediatric patients, this condition can be neurogenic (associated with conditions like spina bifida) or idiopathic. Symptoms include urgency, frequency, and urgency incontinence. Treatment approaches include behavioral therapy, anticholinergic medications, and in severe cases, botulinum toxin injection or surgical intervention. Accurate urodynamic documentation is essential for diagnosis and treatment planning.
Usage
Usage note: Specify neurogenic vs. idiopathic; reference urodynamic findings when available.
