The aim of this study was to evaluate the effectiveness of the pelvic floor muscle training in the stress urinary incontinence. The standard protocol include forty eight treatment sessions all together, for sixteen weeks, three times a week with the using of Plevnik weighted vaginal cones and Kegel exercises. The effectiveness of this method in reducing urine loss was assessed through the "Pad-test" before and after exercises. A cohort of 75 women entered the study, aged between 28 and 66 years old, with mean aged 46 and light to moderate urinary incontinence. The results showed significant improvement with reduction in urine loss and increase in pelvic muscle tone in women that completed the whole treatment course.
