评估女性尿失禁的传统方法包括尿动力学、膀胱尿道镜检查、膀胱尿道造影和超声检查。磁共振（MR）成像在女性尿失禁的评估中并未发挥重要作用。然而，高分辨率 MR 成像可以详细显示女性尿道括约肌和支撑韧带，并可能有助于诊断和分期与内括约肌缺陷或尿道过度活动相关的括约肌功能不全。女性尿道的解剖结构和功能都可以在 MR 图像上描绘。患有压力性尿失禁的女性在 MR 成像中检测到的异常范围分为 (a) 与尿道括约肌缺陷相关的发现和 (b) 尿道支持韧带缺陷和尿道过度活动。这些异常包括尿道肌肉体积小或尿道短、尿道括约肌缺陷、膀胱颈漏斗、尿道支撑韧带扭曲、膀胱膨出、耻骨尾骨肌不对称、阴道形状异常、耻骨后间隙增大和膀胱尿道角增大。 (C) 北美放射学会，2006 年。
The traditional methods for evaluation of urinary incontinence in women include urodynamics, cystourethroscopy, cystourethrography, and ultrasonography. Magnetic resonance (MR) imaging has not played a major role in the assessment of women with urinary incontinence. However, high-resolution MR imaging allows detailed visualization of the urethral sphincter and supporting ligaments in women and may contribute to the diagnosis and staging of sphincteric incompetence related to intrinsic sphincter deficiency or urethral hypermobility. Both the anatomy and the function of the female urethra can be depicted on MR images. The spectrum of abnormalities detected at MR imaging in women with stress urinary incontinence are classified as (a) findings related to the urethral sphincter deficiency and (b) defects of the urethral support ligaments and urethral hypermobility. These abnormalities include a small urethral muscle volume or a short urethra, defects in the urethral sphincter, funneling at the bladder neck, distortion of the urethral support ligaments, cystocele, an asymmetric pubococcygeus muscle, abnormal shape of the vagina, enlargement of the retropubic space, and an increased vesicourethral angle.
