Aims Our aim was to evaluate, in a second data analysis of the prospective randomized controlled trial conducted by Austrian Urogynaecology Working Group, the effect of age, BMI and parity at the time of surgery on short- and long-term outcomes of women primarily treated for SUI (stress urinary incontinence) with midurethral slings. Methods In the original study 554 patients received randomly a retropubic (TVT) or a transobturator midurethral (TVT-O) sling procedure. 480 (87%) and 277 (50%) patients were available for a follow-up efficacy evaluation at 3 months and 5 years respectively. Results Higher age and BMI at surgery appear to lead to a larger probability to have a positive stress test 5 years after surgery, but not after 3 months. Older patients seem to have a worse perception of improvement 5 years after surgery as compared to younger ones, as described by the PGI-I score. Age and BMI do not affect significantly the quality of life of women surgically treated for SUI, as reflected by the results of King´s Health Questionnaire. Parity does not seem to have any effect on objective and subjective surgical outcomes. Conclusions Higher age and BMI at surgery have a detrimental influence on the objective cure rate at 5 years after midurethral sling surgery; higher age also has a negative influence on subjective long-term outcomes. However, these demographic parameters do not influence significantly the quality of life of patients after anti-incontinence surgery. Parity does not show any significant influence on success rate of midurethral sling.
