Bladder dysfunction represents a frequent and important clinical problem in stroke patients. The aim of this narrative review was to explore the currently available information regarding the diagnosis and management of bladder dysfunction following stroke. The most common symptoms of bladder dysfunction following stroke are urinary incontinence, urgency, increased frequency, and difficulty voiding. Medical history, including voiding diary, physical examination, and urodynamic studies are useful in establishing diagnosis. Bladder pressure in stroke patients with detrusor overactivity is rarely high enough to damage the upper urinary tract. In neurogenic bladder, however, there is always a risk for transmission of intravesical pressure to the upper tract. In incontinent patients, urodynamic studies can reveal bladder hyper- or hyporeflexia, detrusor overactivity with impaired contractility or detrusor-sphincter dyssynergia, or even no abnormalities at all. With stroke patients with urinary dysfunction, establishing a proper diagnosis is of paramount importance to start appropriate treatment, prevent upper tract damage, maintain continence, and ensure complete emptying. After diagnosis, an individually tailored treatment plan is mandatory, including behavioral techniques, lifestyle interventions, and anticholinergic medication. Other therapeutic choices include alternative drugs, intradetrusor injection of botulinum toxin, and spinal neuromodulation. A bladder rehabilitation program is essential for improving post-stroke lower urinary symptoms and depends on the patient's awareness, cooperation, and independence. Bladder dysfunction after stroke, as a strong prognostic factor of disability, exerts an enormous impact on health and economy. Therefore, every single effort toward a proper diagnosis and effective rehabilitation is crucial.
