If the foreskin can then no longer be pulled back over the glans, paraphimosis occurs. It is a real vicious circle, in which the arterial blood is pumped under high pressure into the glans while the venous low-pressure system is clamped by the constriction. Ultimately, a kind of "strangulation" of glans occurs accompanied by necrosis of the front part of the penis.
Paraphimosis is visually easy to identify.
The constriction band is cut and expanded, which can be done under local anesthesia.
