Objective (s): To compare non-invasive urodynamic findings in women with and without pelvic floor distress and to investigate the patient characteristics affecting maximum flow rates. Study design: This is a retrospective study including data derived from a prospective cohort study evaluating free uroflowmetry findings in asymptomatic and symptomatic women with urinary dysfunction attending the gynecology outpatient clinic for routine annual control, infertility, abnormal uterine bleeding and pelvic floor dysfunction. Data regarding baseline characteristics, questionnaires, urogynecologic examination findings and free uroflowmetry results were retrieved. Women were grouped according to the Turkish validated Pelvic Floor Distress Inventory (PFDI-20); women who scored 0 or 1 points for each item (“no” or “not at all”) were considered as asymptomatic in terms of pelvic floor dysfunction, and women who scored 2 or more points to any item were accepted as symptomatic. Baseline characteristics, clinical examination findings and free uroflowmetry data were compared among the groups using Student's-t or Mann-Whitney U tests, Chi-square test or Fisher's exact tests, where appropriate. Correlations and their significance, and patient characteristics affecting Qmax were investigated using the Pearson test. A multiple linear regression model was used to identify independent factors affecting Qmax. Results: The study population (n = 186) comprised asymptomatic (n = 70, 37.6%) and symptomatic (n = 116, 62.4%) women according to the scores of the PFDI-20. Corrected Qmax, TQmax, Tvv and PVR were found significantly lower in asymptomatic women (p ≤ 0.001). In asymptomatic women, PVR was <100 mL in 98.5%, and <50 mL in 80%. In multivariate linear regression analysis parity, obstructive subscale score of the UDI-6, previous mid-urethral sling surgery and hysterectomy were found to affect Qmax negatively, whereas VV was found to affect Qmax positively. Conclusion(s): Although significantly different, overlapping wide ranges of non-invasive urodynamic findings have been observed in women with and without pelvic floor distress in the present study population. Maximum urinary flow rates were significantly affected by patient characteristics such as parity, obstructive symptoms, prior incontinence surgery and hysterectomy. There is need for further larger studies considering all possible factors that may affect voiding.
