BACKGROUND: For women with overactive bladder (OAB), current guidelines recommend the use of urodynamic studies (UDS) only in complicated cases. This study aimed to investigate whether UDS can also be helpful in uncomplicated cases. Specific aims of the study were (a): to evaluate objective benefit and subjective patient satisfaction with tailored treatment based on the UDS diagnosis compared to the outcomes of the pharmacological treatment only based on the symptoms; (b) to investigate the correlation between symptoms and UDS findings in women with uncomplicated idiopathic OAB symptoms; (c) to assess the ability of UDS to modify management decisions in these patients.
METHODS: Women presenting to our clinic with a history of uncomplicated OAB symptoms for the past three months or more, and who completed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), were considered for this study. We proposed UDS to all participants. In women who accepted UDS (group 1), management decisions were made on the basis of urodynamic findings and post-treatment evaluation was scheduled at three months. The outcomes of treatments in these patients were compared to the results in women who did not accept UDS and who received pharmacological treatment symptoms-based (group 2). Objective outcomes were based on completion of a 3-day micturition diary. Subjective outcomes were captured using the Overactive Bladder Questionnaire Short Form (OABq-SF), the Patient Global Impression of Improvement (PGI-I) scale, and a patient satisfaction scale.
RESULTS: A total of 680 women were enrolled in the study; 478 underwent UDS and 202, at the contrary, declined UDS. In 53.6% of cases, UDS led to modification of the proposed management approach. At the 3- month follow-up, the overall patient satisfaction rate in group 1 and group 2 was 77 % and 65.8%, respectively (p=0.003).
CONCLUSIONS: we showed that OAB management tailored according to the UDS diagnosis results in higher subjective satisfaction if compared with a pharmacological treatment symptoms-based. Our study confirmed a lack of correlation between OAB symptoms and the urodynamically proven diagnosis of detrusor overactivity (DO). It also suggested that UDS can determine the underlying pathophysiology of every woman with OAB syndrome, whether complicated or uncomplicated, allowing treatment to be appropriately tailored with better results.
