The external application site is located between the tuber ischiadicum, ligamentum sacrospinotuberale latum, rectum, and musculus coccugeus. The procedure involves cleaning and disinfecting the skin, followed by the local anaesthetic (2% procaine) application. A long needle is then introduced pararectally, targeting the area in front of the foramen ischiadicum minus and above the nervus pudendus internus. Additional anaesthesia may be injected caudally and dorsally to this location. The prolapse of the penis occurs within 20-30 minutes after the application of anaesthetics.
