Geriatric considerations in the diagnosis and management of overactive bladder

Numerous considerations affect the diagnosis and management of overactive bladder (OAB) in older patients, including neurologic and cardiovascular disorders, musculoskeletal conditions, diabetes, and psychiatric disorders. Older patients are commonly prescribed multiple medications, and many medications can contribute to OAB symptoms and/or interact with drug treatment for OAB. In addition to chronic illnesses and related medications, several factors outside the lower urinary tract can play an important part in managing OAB in older patients. These factors include mobility disorders, cognitive impairment, bowel habits, and fluid intake. Moreover, OAB often does not occur in isolation in the geriatric population. Estrogen deficiency and sphincter weakness in women, prostatic enlargement and obstruction in men, and impaired bladder contractility in both sexes are common and can have prominent effects on management. The diagnostic evaluation of geriatric patients with OAB can usually be accomplished with a basic assessment, without more invasive and expensive procedures. Treatment depends on numerous factors, ranging from comorbidities and functional status to transportation, finances, and patient and caregiver preferences. Adverse effects of bladder-relaxant medications can be bothersome and exacerbate existing conditions common in older patients (eg, constipation, glaucoma, gastroesophageal reflux, and dementia). Setting realistic goals for treatment and communicating them clearly to older patients and their caregivers are crucial for patient satisfaction. There are myriad opportunities for research designed to improve the management of OAB in the geriatric population.
