Clinical and urodynamic effects of tolterodine in women with an overactive bladder

ObjectiveThe aim of this study was to compare the changes in urinary symptoms and urodynamic parameters after administration of tolterodine in women with an overactive bladder (OAB).Materials and MethodsThirty-eight women diagnosed with OAB and treated with tolterodine were reviewed. Urinalysis, pelvic examination, 3-day bladder diary, urodynamic study, and a personal interview to identify urinary symptoms prior to and 3 months after treatment were recorded and interpreted.ResultsMost of our patients were menopausal (76.3%; mean age 55.7 years) and multiparous (mean parity 3.3) women. Urinary symptoms such as urinary frequency, urgency, urge incontinence, and nocturia were decreased significantly (p < 0.05). All urodynamic parameters did not change significantly except for the maximum cystometric capacity (p < 0.05), showing a significant increase after 3 months of medication.ConclusionsTolterodine, at a recommended dose, improves the symptoms of OAB syndrome without causing urine retention, as proved by the changes of urodynamic parameters.
