Epidemiology
Prevalence increases with age
Etiology
The condition is caused by sensory or motor dysfunction.
- Idiopathic (most common)
- Neurological conditions
Pathophysiology
Inflammatory conditions (e.g., UTI) or neurogenic disorders → sphincter dysfunction, detrusor overactivity, or overactive bladder → autonomous contractions of the detrusor muscle and premature initiation of a normal micturition reflex
Clinical features
- Urinary urgency: sudden urge to urinate
- Loss of urine without exertion, with urinary tenesmus → frequent episodes, with variable volumes of urine voided each time

Treatment
Mnemonic
