Aims: The aim of this study was to determine the relationship between subjective symptom severity and clinical or urodynamic parameters and to compare these parameters according to subjective symptom severity. Methods: A total of 268 female patients with grade II (n = 94) and grade III (n = 174) according to the Ingelman-Sundberg scale were included in the study. Mean patient age was 55.9 years (range 28-80). Of 268 patients, 196 women (73.1%) complained of stress urinary incontinence (SUI) and 72 (26.9%) reported additional symptoms of urge urinary incontinence (UUI). Fifty-four (20.1%) women previously had hysterectomies and 12 (4.5%) underwent surgery for UI. Results: Patients with severe incontinence (grade III) are older, have longer duration of symptoms, concomitant urgency or UUI, and low maximal urethral closure pressure and low Valsalva leak point pressure (VLPP). No difference in other characteristics including pad test loss and urethral mobility was observed in the two groups. In the multivariate logistic regression analysis, a longer duration of symptoms was associated with an increased likelihood of severe symptoms (P = 0,025). Patients with mixed incontinence were at five-fold increased risk of severe symptoms compared with those with SUI only (P = 0.011). In the same model, increasing VLPP was associated with a decreased likelihood of severe symptoms (P = 0.037). Conclusions: Longer symptom duration, mixed incontinence and low VLPP have independent effects on the severity of incontinence. Our findings suggest that incontinent patients with sphincteric impairment or urge component may have and increased probability of severe symptoms.
