Control group. Nulliparous female 20 years. 2D ultrasound shows a normal ARA (100°). No detected rectocele or intussusception. 3D ultrasound shows: At rest (b): levator area: transverse diameter 3.7 cm. AP diameter 4.5 cm. Hiatal area: 14.5 cm2. Thickness of internal sphincter 2 mm (Arrow). Thickness of external sphincter 1.9 mm (arrow head). Thickness of PRS about 4 mm (double arrows). During squeezing (c): levator area: transverse diameter 3.3 cm. AP diameter 4.3 cm. Hiatal area 9.9 cm2. Thickness of internal sphincter 1.9 mm (arrow). Thickness of external sphincter 1.5 mm (arrow head). Thickness of PRS about 3.6 mm (double arrows). During straining (d): levator area: transverse diameter 4 cm. AP diameter 4.8 cm. Hiatal area: 15.6 cm2 thickness of internal sphincter 2 mm (arrow). Thickness of external sphincter 1.9 mm (arrow head). Thickness of PRS about 5 mm (double arrows)
