Transrectal linear ultrasonography was performed on 59 male patients with dysuria, and voiding movement of the posterior urethra was observed with a videomonitor. Uroflowmetry was performed simultaneously, and the results were compared with those obtained in a previous study. On the image synchronized with maximum flow rate, the diameter of the bladder neck, and the center of the prostatic urethra were measured as parameters and the correlation with maximum flow rate, average flow rate, and residual urine rate, was examined. The forward movement of the ventral side of the posterior urethra was found to play a more important role in the opening of the posterior urethra, than the opening of the bladder neck, and the width of the prostatic urethra to play a more important role in the efficiency of urination than the width of the bladder neck.
对59例排尿困难的男性患者进行经直肠线性超声检查，并通过视频监视器观察后尿道的排尿动作。同时进行尿流率测定，并将结果与先前研究中获得的结果进行比较。在与最大尿流率同步的图像上，测量膀胱颈直径和前列腺尿道中心作为参数，并检查其与最大尿流率、平均尿流率和残余尿率的相关性。发现后尿道腹侧的向前移动在尿道开口方面比膀胱颈开口起更重要的作用，并且前列腺尿道宽度在排尿效率方面比膀胱颈宽度起更重要的作用。
