目的采用盆底动态MRI与同步联合盆腔器官造影术对比研究女性盆底功能失调,寻找女性盆底功能失调的最佳影像学检查模式。方法对30例盆底功能失调患者分别行同步联合盆腔器官造影术(膀胱尿道造影加腹膜腔造影加阴道造影加排粪造影)和盆底动态MRI检查,比较两种影像检查结果之间的相关性。结果盆底动态MRI与同步联合盆腔器官造影术对评价膀胱颈膨出的诊断符合率为100%,其次依次是肛直肠连接异常下降(95.2%),盆底陷窝疝(86.7%)和子宫颈脱垂(85.7%)。但同步联合盆腔器官造影术检出12例直肠膨出和直肠黏膜脱垂或套叠28例(93.3%),而盆底动态MRI仅检出6例(50.0%)直肠膨出。盆底动态MRI的平均检查时间是(16±3)min。同步联合盆腔器官造影术为(34±9)min(P<0.01)。结论盆底动态MRI结合排粪造影术是全面评价女性盆底功能失调的最佳影像学检查模式。
Objective To compare pelvic floor dysfunction with pelvic floor dynamic MRI and simultaneous pelvic organ angiography in order to find the optimal imaging modality for female pelvic floor dysfunction. Methods Thirty patients with pelvic floor dysfunction were treated with simultaneous pelvic organ angiography (intraurethral urethral catheterization combined with peritoneal contrast plus vaginal contrast plus defecography) and dynamic pelvic MRI examination. The correlation between the two imaging findings was compared Sex. Results The coincidence rate of pelvic floor dynamic MRI and simultaneous pelvic organ angiography was 100% for the diagnosis of bladder neck bulge, followed by the decrease of anorectal connection (95.2%), pelvic floor hernia (86.7%) and cervix Prolapse (85.7%). However, synchronous pelvic organ angiography detected 12 cases of rectal prolapse and rectal mucosal prolapse or nested 28 cases (93.3%), while pelvic floor dynamic MRI detected only 6 cases (50.0%) rectal prolapse. The mean pelvic dynamic MRI examination time was (16 ± 3) min. Synchronized pelvic organ imaging was (34 ± 9) min (P <0.01). Conclusion pelvic floor dynamic MRI combined with defecography is a comprehensive evaluation of female pelvic floor dysfunction best imaging examination mode.
