A foreskin that has been pulled back and will not return, leaving a tight band behind the head of the penis. Swelling builds quickly, so this is the one foreskin problem that needs same day hospital care rather than a clinic appointment.

Paraphimosis happens when a tight foreskin is retracted behind the head of the penis and then cannot be brought forward again. The narrow ring of skin acts like a tourniquet. Blood can still flow in, but drainage out is restricted, so the head and the foreskin swell steadily. The more they swell, the tighter the ring becomes.
That self worsening cycle is what makes it urgent. Within a few hours the swelling can become severe and increasingly painful. Left far longer, the blood supply to the tissue itself can be compromised, which is rare but serious.
It is nearly always preventable. Almost every case begins with an underlying tight foreskin, and correcting that tightness is what stops it happening again.
It is far less common than simple tight foreskin, but it is not rare, and it is one of the few genuine male genital emergencies. It occurs most often in men who already have phimosis and who retracted the foreskin for washing, for sex or for a catheter to be passed, and then did not return it.
It also happens in hospital settings after examination or catheter insertion, which is why returning the foreskin to its natural position afterwards matters so much.
The picture is usually obvious and it develops over hours rather than days. Recognising it early makes treatment far simpler.
There is almost always an underlying tightness, plus a moment when the foreskin was retracted and left behind the glans.
This condition does not wait. The rule is simple: if the foreskin will not come forward, seek help the same day.
Attend a hospital emergency department immediately if the foreskin cannot be returned. Do not wait to see whether it settles overnight. Early treatment is usually a simple manual reduction after local anaesthesia, while delay makes a surgical release far more likely.
Diagnosis is visual and immediate. The clinical questions are how long it has been present and whether the tissue remains healthy.
A retracted foreskin with a tight band behind the glans and increasing swelling is diagnosed on sight. No scan or blood test is required to confirm it.
Colour, temperature, sensation and how long the foreskin has been trapped are checked, since these determine whether simple reduction is still possible.
Local anaesthesia, cooling and steady compression to squeeze fluid out of the swollen tissue, followed by gentle reduction. A small release incision is used where compression alone fails.
Once swelling has settled, the underlying tightness is assessed and blood sugar is checked. Definitive surgery is then scheduled at a time that suits you.
Once the foreskin has been reduced, the swelling settles over a few days and the tissue recovers fully in the great majority of men. The important part is what comes next. Without treating the underlying tightness the risk of it happening again is real, and repeat episodes tend to be worse.
For most men the definitive answer is circumcision surgery, planned at a time that suits you once the tissue has settled. Selected men with mild tightness may instead be suitable for a foreskin preserving widening procedure.
Emergency reduction is normally carried out in a hospital setting and is charged as an emergency attendance. Planned treatment afterwards is quoted separately and depends on the procedure chosen, the anaesthesia used and how much scarring the episode has left behind. A single all inclusive figure covering surgeon, theatre, dressings and follow up is given after examination.
Emergency care relieves the constriction. Planned treatment afterwards deals with the tightness that allowed it to happen.
Cooling, local anaesthesia and sustained gentle compression to reduce the swelling enough for the foreskin to be eased forward. Effective in most men who attend within a few hours.
Ask about thisA small incision through the constricting band to release it immediately. It relieves the emergency but leaves the foreskin needing definitive treatment once everything has settled.
Ask about thisRemoval of the foreskin at a later, planned date once inflammation has resolved. This is the treatment that reliably prevents a further episode in men with established tightness.
Ask about thisWhere tightness is mild and the tissue is otherwise healthy, a widening procedure can keep the foreskin while removing the constricting ring. Not suitable where scarring is established.
Ask about thisClearing infection, controlling blood sugar and reviewing any skin condition affecting the area. These reduce both the swelling that triggered the episode and the risk of recurrence.
Ask about thisOnce the emergency has been dealt with, the underlying tight foreskin still needs attention or the problem can return. Our genital surgery and aesthetics section sets out every foreskin procedure we offer and how each one is chosen.
Genital Surgery and AestheticsStraight answers about this concern, written for men in Surat.
Ask a QuestionThey are related but different. A tight foreskin means it will not pull back. This condition is the opposite situation: it has pulled back and now will not go forward, forming a constricting ring. The tightness is the underlying cause, which is why it needs treating afterwards.
Genuinely urgent. Swelling worsens the constriction, which worsens the swelling, so the window for a simple reduction narrows by the hour. Treated within a few hours it is usually straightforward. Left overnight it often needs a surgical release instead.
Gentle steady pressure sometimes works in the first few minutes, before swelling builds. Forcing it is a bad idea, because it causes tears that scar. If it does not return easily and quickly, stop and attend a hospital rather than persisting at home.
Local anaesthesia and cooling reduce the swelling, then steady compression squeezes fluid out of the tissue so the ring can be eased forward. Where that fails, a small cut releases the tight band. Both are done under anaesthesia and both give immediate relief.
It can, if the underlying tightness is left untreated. That is why a planned review is arranged once the swelling has settled. Men who go on to have the tight ring corrected very rarely experience a second episode.
Not when it is treated promptly. Tissue recovers fully in the great majority of men. Prolonged constriction over many hours can damage the skin and, very rarely, compromise the blood supply, which is the reason for insisting on same day attention.
Always return the foreskin to its natural position after washing, after sex and after any medical examination or catheter insertion. If the foreskin is tight enough to become stuck, have that tightness assessed rather than living carefully around it.
