Answer

Urge incontinence is the involuntary loss of urine associated with a strong urge to void. Motor urge incontinence is associated with increased contractibility of the detrusor during the filling phase. The patient experiences uninhibited bladder contractions that are perceived as an urgent need to void even at low bladder volumes.

These contractions may be associated with outflow obstruction (eg, benign prostatic hyperplasia [BPH]), inflammation (eg, urinary tract infection or radiation cystitis), or neurologic disorders, usually involving suprapontine lesions. Normally, small contractions of the bladder elicit strong contraction of the sphincter, which then suppresses the contraction.
