OBJECTIVES: The administration of empirical anticholinergic treatment is widespread in women with urinary incontinence and has produced varied results. The objective of our paper is to determine the effectiveness of anticholinergics for the treatment of female urinary incontinence and to determine by urodynamicsthe possible causes that may explain the resistance to anticholinergics to obtain urodynamic predictors of success or failure. %26lt;br%26gt;METHODS: We evaluated 182 women over 14 years of age with urinary incontinence that had previously been treated with anticholinergics for at least three months. The patients underwent a complete medical history including clinical history, physical examination, and urodynamic and lower urinary tract video-radiologic studies. Statistical analysis was performed using SPSS 17.0 for Windows. %26lt;br%26gt;RESULTS: Clinical therapeutic efficacy was demonstrated in 39.6% of cases. Cystometric bladder capacity was decreased in 89.2% of patients that did not improve clinically with anticholinergics (p=0.01). Detrusor overactivity was urodynamically demonstrated in 51% of cases (p = 0.05) among patients without clinical improvement with anticholinergic treatment. This hyperactivity was demonstrated during early bladder filling (%26lt;100ml). Urodynamic stress urinary incontinence (SUI) was demonstrated in 26.5% of patients without clinical improvement after treatment (p=0.04). Lower urinary tract obstruction was urodynamicallydemonstrated in 20.6% of patients with no clinical improvement (p=0.05). Urodynamic data did not demonstrate a relationship between detrusor overactivity, a highgrade cystocele (37.4% of total), and irregular bladder morphology (11.5% of total). %26lt;br%26gt;CONCLUSIONS: It is important to conduct urodynamic study before starting anticholinergic treatment of females with urinary incontinence to identify therapeutic data of poor prognosis, such as SUI and lower urinary tract obstruction, thus optimizing the therapeutic efficacy of anticholinergics.
