Four Years' Experience at a Single Referral Center Regarding Urodynamic Findings in Women With Voiding Dysfunction

This study aimed to evaluate the urodynamic findings in women with voiding dysfunction symptoms at a referral academic center.

Patients who underwent urodynamics to evaluate voiding dysfunction symptoms between 2019 and 2022 were retrospectively analyzed. Demographic and clinical data were obtained from the electronic data registration system of the urogynecology clinic. Urodynamic findings, such as post-void residual (PVR), maximum urine flow (Q max), detrusor pressure (P det), abdominal leak point pressure (ALPP), and detrusor overactivity, as well as their association with each symptom of voiding dysfunction, were analyzed and reported.

A total of 591 women were enrolled in the study, with a mean age of 54.09±12.3 years. The majority had experienced vaginal deliveries (82.9%). The most frequently reported symptom was incomplete voiding (71.1%), followed by post-void dribbling, intermittent stream and others. Post-void residual (PVR) >150 cc was identified in 2.7% of patients and was significantly associated with hesitancy and straining to void. It was also associated with increasing age and anterior and apical compartment prolapse.

Voiding dysfunction symptoms do not reliably predict urodynamic findings. The low prevalence of post-void residual (PVR) in symptomatic patients and the lack of correlation between PVR and similar symptoms suggest that symptoms alone may not provide adequate evidence to indicate high PVR. Therefore, urodynamics may be necessary for evaluating patients with voiding dysfunction symptoms.
