This study explored using an improved ultrasound (US) for quantitative evaluation of the degree of pelvic organ prolapse(POP).
A transluminal probe was used to standardize ultrasound imaging of pelvic floor organ displacements. A US reference line was fixed between the lower edge of the pubic symphysis and the central axis of the pubic symphysis at a 30°counterclockwise angle.
Points Aa, Ba, C and Bp on pelvic organ prolapse quantification (POP-Q) were then compared with the points on pelvic floor ultrasound (PFUS).
One hundred thirteen patients were included in the analysis of the standard US plane. Correlations were good in the anterior and middle compartments (PBN:Aa, ICC = 0.922; PBB:Ba, ICC = 0.923; and PC:C, ICC = 0.925), and Bland-Altman statistical maps corresponding to the average difference around the 30°horizontal line were close to 0. Correlations were poor in the posterior compartment (PRA:Bp, ICC = 0.444). However, eight (7.1%) cases of intestinal hernia and 21 (18.6%) cases of rectocele were diagnosed.
Introital PFUS using an intracavitary probe, which is gently placed at the introitus of the urethra and the vagina, may be accurately used to evaluate organ displacement. The application of a 30°horizontal line may improve the repeatability of the US diagnosis of POP.
本研究探讨了一种改良的超声（US）在定量评估盆腔器官脱垂（POP）程度中的应用。
采用经阴道探头对盆底器官移位进行超声成像标准化。在耻骨联合下缘和耻骨联合中轴线之间以逆时针 30°角固定一条 US 参考线。
然后将盆腔器官脱垂定量（POP-Q）的 Aa、Ba、C 和 Bp 点与盆底超声（PFUS）的点进行比较。
113 例患者纳入标准 US 平面分析。前、中隔相关性良好（PBN:Aa，ICC=0.922；PBB:Ba，ICC=0.923；和 PC:C，ICC=0.925），30°水平线周围平均差异的 Bland-Altman 统计图谱接近 0。后隔相关性较差（PRA:Bp，ICC=0.444）。然而，诊断出 8 例（7.1%）肠疝和 21 例（18.6%）直肠膨出。
采用经阴道腔内探头轻柔放置于尿道和阴道入口处的阴道入口 PFUS 可准确评估器官移位。30°水平线的应用可能提高 US 诊断 POP 的重复性。
