There are no standardized definitions for anti-incontinence therapy outcomes. The present study was conducted to evaluate whether the incorporation of several non-invasive outcome measures into a new score may serve as a meaningful outcome instrument. Ninety-four consecutive sphincteric incontinent women who underwent a pubovaginal sling by a single surgeon were enrolled. All patients underwent a full clinical evaluation, including pre-and post-operative questionnaires, 24-hour voiding diary, and 24-hour pad test. Surgery outcomes were classified twice: First, by analyzing the patient questionnaire, voiding diary, and pad test separately, according to previously published criteria, and second, by combining the three outcome tools into a new response score. The new score was constructed in a simple, easy-to-remember format and divided into five categories: cure, good response, fair response, poor response, and failure. All patients were evaluated at least 1 year postoperatively. Comparison of the old and new classifications suggests that the new response score provides a more accurate evaluation of the surgical outcomes. Although 64 to 69% of the patients were originally classified as cure according to the old classification, only 44.7% were re-classified as cure by the strict criteria employed in the new score. Furthermore, the response score also differentiates between various degrees of clinical improvement (i.e., good, fair, or poor response). Twenty-five (26.6%) patients, most of whom were previously classified as cure, were re-classified as good response, whereas 20 others were re-classified as fair (13.9%), or poor (7.4%) response. Seven (7.4%) patients were re-classified as surgical failures. All were diagnosed pre-operatively as having complex sphincteric incontinence. Specific failure rates were therefore 11.3% for complex and 0% for simple cases. In conclusion, the suggested post-operative response score incorporates in a user-friendly format three popular outcome tools (i.e., 24-hour diary, 24-hour pad test, and patient questionnaire) and seems to reflect the surgical results more accurately. Further studies are needed to assess its validity and reproducibility in other treatment modalities. Neurourol Urodynam. 19:127-135, 2000.
