Treatment of overactive bladder syndrome with urethral calibration in women - Abstract

Our objective was to determine whether urethral calibration with Walther's urethral sounds may be an effective treatment for overactive bladder syndrome. The diagnosis of overactive bladder syndrome is a clinical one based on the presence of urgency, with or without urge incontinence, and is usually accompanied by frequency and nocturia in the absence of obvious pathologic or metabolic disease. These symptoms exert a profound effect on the quality of life. Pharmacologic treatment is generally used to relieve symptoms, however anticholinergic medications may be associated with several undesirable side effects. There are case reports of symptom relief following a relatively quick and simple office procedure known as urethral dilation. It is hypothesized that this may be an effective treatment for the symptoms of overactive bladder. Women with clinical symptoms of overactive bladder were evaluated. Eighty-eight women were randomized to either urethral calibration (Treatment), or placebo (Control) treatment. Women's clinical outcomes at two and eight weeks were assessed and compared between the two treatment arms. Eight weeks after treatment, 31.1% (n=14) of women who underwent urethral calibration were responsive to the treatment versus 9.3% (n=4) of the Control group. Also, 51.1% (n=23) of women within the Treatment group showed at least a partial response versus 20.9% (n=9) of the Control group. Our conclusion is that Urethral calibration significantly improves the symptoms of overactive bladder when compared to placebo and may be an effective alternative treatment method.
