In patients with voiding dysfunction, VU\u2010TRUS during voiding revealed various urethral abnormalities, including 16 detrusor sphincter dyssynergia, 4 detrusor bladder neck dyssynergia, and 13 insufficient opening of the entire urethra. VU\u2010TRUS also showed pelvic floor abnormalities, including 24 urethral hypermobilities (group 1) and 11 cystoceles (group 2). Eighteen patients had neither urethral hypermobility nor cystocele (group 3). Major pressure\u2010flow abnormalities in the 53 patients with voiding dysfunctions were weak detrusor (72%) and\/or bladder outlet obstruction (25%). There were no significant differences in the distribution of the pressure\u2010flow abnormalities among the three groups. However, the mean values of abdominal pressure at maximum flow of group 1 (20.9 cm H<jats:sub>2<\/jats:sub>O) and group 2 (17.9 cm H<jats:sub>2<\/jats:sub>O) were significantly higher than that of group 3 (6.3 cm H<jats:sub>2<\/jats:sub>O; each <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).
