However, the associations between the urethral volume and potential affecting factors still remain uncertain. The aim of this study was to investigate the impact of potential factors, including age, height, weight, body mass index (BMI), parity number, delivery mode, and menopause, on the midurethral volume to assist in more\u2010accurate evaluations of urethral anatomy and urinary continence mechanisms in clinical practice.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 244 women were included in this study. All patients had no incontinence symptoms and underwent transvaginal ultrasound examinations. Detailed histories and demographic data were collected. Urethral volumes were acquired, and volume parameters were measured offline, including the urethral sphincter volume (USV), midurethral complex volume (CV), and inner core volume (ICV). Correlations were analyzed by the Spearman test. For categorical variables, an analysis of variance, Mann\u2010Whitney tests, or Kruskal\u2010Wallis tests were used to estimate associations of potential affecting factors and volumes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean age, height, weight, and BMI\u2009\u00b1\u2009SD of the patients were 35.42\u2009\u00b1\u20099.88\u2009years, 161.50\u2009\u00b1\u20094.96 cm, 60.72\u2009\u00b1\u200911.42 kg, and 23.29\u2009\u00b1\u20094.20 kg\/m<jats:sup>2<\/jats:sup>, respectively.
