Compare pelvic structure location on MRI during maximal Valsalva among women with posterior prolapse and those with normal support. All underwent mid-sagittal, dynamic MRI. Structure locations distal vagina, apex, perineal body, external anal sphincter were determined. PVW length, levator and urogenital hiatus diameters, and prolapse diameter were measured.
Quantitative analyses of variability in normal vaginal shape and dimension on MR images
We present a technique for quantifying inter-individual variability in normal vaginal shape, axis, and dimension, and report findings in healthy women. The coefficient of determination between any demographic variable and any vaginal dimension did not exceed 0. Large variations in normal vaginal shape, axis, and dimensions were not explained by body size or other demographic variables. This variation has implications for reconstructive surgery, intravaginal and surgical product design, and vaginal drug delivery. The goal of reconstructive surgery is to restore normal anatomy and function.
Pelvic Floor Dysfunction pp Cite as. Enterocele has been defined as a peritoneum-lined sac her-niating through the pelvic floor, usually between the vagina and rectum. Nichols and Randall described four types, including traction, congenital, pulsion, and iatrogenic. Traction enterocele is probably the most common and occurs secondary to uterine and vaginal apical prolapse.
