To investigate the role of measuring the thickness of pelvic floor muscles with static MRI in the physiopathology of urinary incontinence in women with stress and mixed types of urinary incontinence diagnosed with urodynamic studies.
A retrospective clinical study was designed in collaboration with the radiology department. We recruited only patients who had undergone static pelvic MRI to determine the etiology of pelvic pain and exclude gynecologic disorders. The study included 45 women diagnosed with stress or mixed-type urinary incontinence based on pelvic examination and urodynamic testing without symptomatic pelvic organ prolapse and 40 continent controls. We evaluated the images of pelvic static MRI of all patients to measure the thickness of the pelvic floor muscles with the radiologist by using an image analysis workstation retrospectively.
The right and left puborectalis parts of levator ani muscle thicknesses were significantly lower in the urinary incontinence group than in the control group (p < 0.01). The right and left PR/OI ratios were significantly lower than in the control group. (p = 0.001).
Morphologic changes of pelvic floor muscle thickness can be demonstrated by a static pelvic MRI, and this can be used as a prognostic test in the treatment and follow-up of patients with stress or mixed urinary incontinence.
通过静态磁共振成像（MRI）测量盆底肌厚度，研究其在经尿动力学检查诊断为压力性和混合性尿失禁的女性尿失禁病理生理过程中的作用。
与放射科合作开展一项回顾性临床研究。我们仅招募了接受过静态盆腔MRI检查以确定盆腔疼痛病因并排除妇科疾病的患者。该研究纳入了45名经盆腔检查和尿动力学测试诊断为压力性或混合性尿失禁且无盆腔器官脱垂症状的女性，以及40名控尿对照者。我们使用图像分析工作站，由放射科医生回顾性评估所有患者的盆腔静态MRI图像，以测量盆底肌厚度。
尿失禁组肛提肌的左右耻骨直肠肌部分厚度显著低于对照组（p < 0.01）。左右PR/OI比值显著低于对照组（p = 0.001）。
静态盆腔MRI可显示盆底肌厚度的形态学变化，这可作为压力性或混合性尿失禁患者治疗和随访的一项预后检测指标。
