Nocturia In Overactive Bladder
Geoffrey W. Cundiff, MD
Nocturia is a disease state that has a significant impact on general health and quality of life. The prevalence of nocturia increases with age. Nocturia is among the most bothersome symptoms that patients with lower urinary tract disorders experience. It has been associated with an increased risk of falls and sleep disruption that can lead to a host of other problems, including excessive somnolence, decreased cognitive and work performance, dizziness, and depression. Treatment of nocturia can have a profound effect on a patient's quality of life. Behavioral and pharmacologic interventions are the most commonly used modalities.1,2
Nocturia has been defined as "the complaint that the individual has to wake at night one or more times to void." It can be a symptom of many different systemic diseases, including overactive bladder (OAB), although it is not part of the diagnostic criteria of OAB.3 The causes of nocturia can be categorized according to the following conditions: diminished nocturnal bladder capacity, nocturnal polyuria, and polyuria. Diminished nocturnal bladder capacity results from disorders, such as OAB, bladder obstruction, urogenital aging, malignancy, and infection. Nocturnal polyuria results from abnormalities in secretion or utilization of arginine desmopressin, obstructive sleep apnea, congestive heart failure, and renal insufficiency. Polyuria results from diabetes mellitus or insipidus. Other causes of nocturia include sleep disorders, peripheral edema, and consumption of excessive fluids shortly before bedtime.4,5
Treatment of nocturia is driven by the underlying cause of the patient's symptoms. A proper diagnostic assessment before starting treatment is crucial to achieving success. A complete medical history, physical examination, and laboratory assessments are needed to exclude polyuria and nocturia resulting from systemic diseases, such as those associated with edema (eg, chronic heart failure or renal disease), decreased renal concentrating capacity (eg, diabetes insipidus or renal insufficiency), and irritative bladder symptoms caused by bacterial cystitis, chronic interstitial cystitis, bladder calculi, or bladder cancer. Details of bladder filling and outflow symptoms should be obtained from the patient to rule out an underlying bladder outlet obstruction. Other factors that should be evaluated include fluid intake, medications, neurologic disorders, and nocturnal apnea. Conservative measures, such as behavior modification therapy (eg, bladder retraining and pelvic floor muscle training) and lifestyle modifications (eg, changes in medication/medication schedule or elevation of legs or use of compression stockings to reduce fluid accumulation), usually are tried before initiation of pharmacologic therapy. Symptoms that are refractory to behavioral and pharmacologic therapy may respond to surgery (eg, sacral nerve neuromodulation).2,5-8
Desmopressin acetate and imipramine have been shown to be effective for the treatment of nocturnal polyuria. Nocturia associated with OAB can be successfully treated with an antimuscarinic agent. Nonselective muscarinic receptor antagonists, including oxybutynin, tolterodine, and trospium, in addition to selective muscarinic receptor antagonists, including darifenacin and solifenacin, have been shown to be effective for the treatment of OAB symptoms. Specifically, in clinical studies, tolterodine, trospium, and solifenacin have been associated with significant decreases in the number of nocturnal voids per day.9-14
Many patients with OAB symptoms, such as nocturia, fail to seek medical assistance because of embarrassment or the misconception that OAB is a natural part of aging. These patients often adopt coping strategies, such as limiting travel to locations near a bathroom or avoiding sexual intimacy, to make the condition bearable; patients may continue using these coping strategies for extended periods of time before consulting a healthcare professional. The treating healthcare professional should be aware of which symptoms are most bothersome to the patient and focus on treatment of those symptoms to ensure patient satisfaction with treatment.15
In this issue of Advanced Studies in Medicine, the review article, authored by Raymond R. Rackley, MD, reviews in detail important issues to consider when diagnosing and treating the patient with nocturia. This review is practical and geared toward the practicing clinician.
An interview with David H. Thom, MD, PhD, details the considerations of the primary care physician (PCP) when diagnosing and treating a patient with nocturia. In an interview with Eric S. Rovner, MD, the steps to be taken to assess, diagnose, and manage nocturia are described while providing Òclinical pearlsÓ regarding the important interactions between the PCP and the specialist.
Drs Thom and Rovner also present a case that illustrates the importance of the interaction process between the PCP and specialist in obtaining a successful result for the patient. Phyllis C. Zee, MD, PhD, presents a case that describes the importance of evaluation and treatment to identify the underlying cause of nocturia and associated or comorbid conditions, such as sleep disorders.
