An NP is assessing an older adult patient who reports that when they feel the urge to urinate, they have to go immediately or else they urinate "on themselves." They have become homebound because they want to stay close to a bathroom. What relevant medical history may be a contributing cause for these findings?

The patient is describing urge incontinence — a sudden, overwhelming desire to void that cannot be deferred, leading to involuntary urine loss and behavioral changes such as becoming homebound to stay near a bathroom. Stroke is a well-established cause of urge incontinence because cerebrovascular injury can damage the cortical and subcortical centers that normally suppress detrusor contractions, leading to detrusor overactivity and an inability to inhibit the urge to void. This neurogenic detrusor overactivity produces the classic urge-dominant pattern described in the stem. Arthritis can contribute to functional incontinence, where mobility limitations prevent a person from reaching the toilet in time, but the mechanism here is physical limitation rather than an uncontrollable urge. Cauda equina syndrome damages lower motor neurons and typically produces overflow incontinence with urinary retention and a flaccid bladder, not urge incontinence with a sudden overwhelming urge. Prostate surgery may cause stress incontinence due to sphincter damage, or occasionally urge symptoms from bladder neck scarring, but is not the classic primary cause of the urge-dominated picture described and would not apply here since the patient's sex is not specified as male in this stem. Stroke remains the most consistent contributing history for neurogenic urge incontinence.
