The superficial perineal pouch is an anatomical structure located in the pelvic floor. It contains important muscles such as the bulbospongiosus, ischiocavernosus, and transverse perineal muscles. There are various synonyms that are used to refer to this pouch. These include the ischioanal fossa, urogenital triangle, and superficial perineal space. The ischioanal fossa is a triangular-shaped area that is bounded by the ischium bone and the obturator internus muscle. The urogenital triangle is the anterior part of the perineum that is bordered by the pubic symphysis and the coccyx. The superficial perineal space is the area between the perineal membrane and the skin. The interchangeable use of these terms can help clarify the location and contents of this important structure.
