本研究评估了“中线缺陷”（阴道增宽）和“阴道旁缺陷”（侧阴道与盆腔侧壁分离）的相对贡献。10名女性前占主导地位的脱垂和10个正常的支持进行了盆腔MR成像。生成阴道前壁（AVW）的3-D模型，以确定侧AVW边缘、阴道宽度和顶端位置的位置。在大部分阴道长度，最明显的是阴道中段（效应值2.2-2.8），病例组的AVW边缘比对照组远离其正常位置。阴道宽度在阴道中部不同，效应量为1.0。在阴道中上部，顶侧和阴道旁支撑之间的强相关性是明显的（r=0.77-0.93）。无论是在受累部位数量还是效应量方面，病例组与对照组相比，侧位AVW位置的变化均显著大于阴道宽度的变化。这些“阴道旁缺陷”与心尖下降高度相关。
This study assesses relative contributions of "midline defects" (widening of the vagina) and "paravaginal defects" (separation of the lateral vagina from the pelvic sidewall). Ten women with anterior predominant prolapse and 10 with normal support underwent pelvic MR imaging. 3-D models of the anterior vaginal wall (AVW) were generated to determine locations of the lateral AVW margin, vaginal width, and apical position. The lateral AVW margin was farther from its normal position in cases than controls throughout most of the vaginal length, most pronounced midvagina (effect sizes 2.2–2.8). Vaginal widths differed in the midvagina with an effect size of 1.0. Strong correlations between apical and paravaginal support were evident in mid and upper vagina (r=0.77–0.93). Changes in lateral AVW location were considerably greater than changes in vaginal width in cases vs controls, both in number of sites affected and effect sizes. These "paravaginal defects" are highly correlated with apical descent.
