Anatomical terminology

The urogenital hiatus is a large midline opening[1] in the anteromedial part of the pelvic floor (more precisely, the pubococcygeal muscle),[2] extending between the pubis (anteriorly), and rectum (posteriorly). Each levator ani muscle forms either lateral border of the hiatus.[1]

The hiatus acccomodates the apex of the prostate in males,[1] and gives passage to the urethra in both sexes, the vagina in females, the deep dorsal vein of clitoris (females) or penis (males),[2] and nerves of the penis in males.[1]

Clinical significance

[edit]

The urogenital hiatus has been linked to urinary stress incontinence.[3]
