Penoscrotal entrapment: a safe, innovative technique for removing metal constricting devices

Penoscrotal entrapment is a rare urological emergency that requires urgent treatment to avoid penile ischaemia and subsequent erectile dysfunction. Non-metallic and thin metallic objects are easily removed via cutting, while thick metallic constricting devices require specialist saws or motorised cutters, all of which may be difficult to locate in the emergency setting. We report a case of a 45-year-old patient who presented with a 48-h history of gross penoscrotal oedema secondary to entrapment by a thick metal ring (internal diameter 55 mm, external diameter 74 mm and thickness 19 mm). The positioning, thickness of the ring, delayed presentation and extensive oedema meant its removal was especially challenging. We improvised a simple, three-step technique (aspiration, strapping and sling) which enabled the metal ring to be removed without the need for specialist equipment. We would encourage others to employ this safe technique in an emergency setting.
