In order to investigate the diagnostic reliability of transrectal US in the study of female urinary incontinence, the authors compared the static images obtained by means of colpocystourethrorectography with the ones obtained with transrectal US. The study population included 30 patients suffering from urinary incontinence. US images were obtained both at rest and during Valsalva's maneuver, some minutes before cystourethrography and employing part of its preparation (vesical filling with 250 cc of iodine contrast medium and positioning of a metallic bead chain in the urethra). On static images obtained with cystourethrography and transrectal US both at rest and during Valsalva, 4 parameters were evaluated: anterior and posterior vesical angles, urethral axis angle, and distance between symphysis pubis and urethral-vesical junction. As for posterior vesical angle, urethral axis angle, and symphysis-junction distance, the statistical comparison of the results did non demonstrate any significant differences. Anterior vesical angle was not included because it is too difficult to measure by transrectal US. In our experience, transrectal US was capable of yielding accurate information similar to that obtained with colpocystourethrorectography.
为了研究经直肠超声在女性尿失禁研究中的诊断可靠性，作者将阴道膀胱尿道直肠造影所获得的静态图像与经直肠超声所获得的图像进行了比较。研究人群包括30例尿失禁患者。在膀胱尿道造影前几分钟并采用其部分准备措施（用250 cc碘造影剂充盈膀胱并在尿道内放置金属珠链）时，于静息状态和瓦尔萨尔瓦动作期间获取超声图像。在膀胱尿道造影和经直肠超声于静息状态和瓦尔萨尔瓦动作期间所获得的静态图像上，评估了4个参数：膀胱前后角、尿道轴角以及耻骨联合与尿道膀胱交界处之间的距离。至于膀胱后角、尿道轴角和耻骨联合-交界处距离，结果的统计学比较未显示任何显著差异。未纳入膀胱前角，因为经直肠超声测量该角度过于困难。根据我们的经验，经直肠超声能够提供与阴道膀胱尿道直肠造影所获得的信息相似的准确信息。
