Usefulness of a Sonographic Bladder Scan for Uroflowmetry and the Evaluation of the Anxiety Level Associated with Uroflowmetry

Purpose: Uroflowmetry (UFM) requires at least 125ml to 150ml of urine volume for an adequate interpretation. It is common to repeat UFM in clinical settings because of an insufficient voided volume, which may be induced by increased anxiety. To reduce performing repeated UFMs, we evaluate the usefulness of performing a prevoiding sonographic bladder scan and we determined the anxiety level before performing UFM. Materials and Methods: We enrolled one hundred two patients (mean age: 62.6±15.0 years) who visited our clinic due to voiding dysfunction. The bladder volume prior to UFM was measured by an automated bladder scan (Biocon-500TM, Mcube Technology) when the patients felt a strong fullness sensation. All the patients kept a voiding diary for 3 days, and they underwent the State-Trait Anxiety Inventory questionnaire, the fullness scale and UFM. Results: The mean prevoiding volume was 307±124ml and the mean voided volume was 271±129ml. There was a correlation between th
