Area under the anterior vaginal wall profile. Pubic bone, sacrum, and coccyx are traced. The anterior vaginal wall tracings are shown. A line (small dotted) is used to connect the two ends of the vaginal wall tracing to create an area (shown in gray). Examples aligned using horizontal large dotted reference line. a Minimal descent of most caudal bladder point (triangle). b Greater descent of the bladder point with longer vaginal wall length and larger area. c Similar vaginal wall length to B but smaller area and lesser descent of bladder point
