Paraphimosis (Trapped Foreskin)
Paraphimosis is a urologic emergency in which the foreskin is pulled back behind the head of the penis (glans) and cannot be returned to its normal position. The tight band of foreskin squeezes like a tourniquet, causing painful swelling of the glans and foreskin. If not treated within hours, blood flow can be cut off and tissue can be damaged. It happens only in uncircumcised males, often after cleaning, sex or catheter insertion when the foreskin is not pulled back forward.
Also called: Trapped foreskin, retracted foreskin stuck, foreskin stuck behind glans
At a glance
- What it is
- A retracted foreskin stuck behind the glans, with swelling.
- Who
- Uncircumcised boys and men, especially with a tight foreskin, catheters or after sex.
- Why urgent
- Swelling can block blood flow to the glans within hours.
- Treatment
- Swelling reduction and manual reduction by a clinician; a small incision if that fails.
- Prevention
- Always return the foreskin forward after cleaning, sex, exams or catheter care.
When to get help
Call 911 or go to the ER
- A foreskin stuck behind the head of the penis that cannot be pulled forward: go to the ER now, or call 911 or your local emergency number
- The head of the penis turning dark, blue, black or cold
- Unable to pass urine
See a doctor within a day or two
- Swelling, pain or redness of the foreskin after it was retracted, even if it can be returned
Book a routine appointment
- A tight foreskin that is difficult to retract or return (phimosis)
- Recurrent redness, itching or discharge under the foreskin (balanitis)
Paraphimosis vs phimosis
| Phimosis | Paraphimosis | |
|---|---|---|
| Problem | Foreskin too tight to pull back | Retracted foreskin cannot be returned forward |
| Urgency | Usually not urgent | Emergency |
| Who | Normal in young boys; can be pathological in adults | Uncircumcised males of any age |
A tight foreskin (phimosis) is a major risk factor for paraphimosis, because a narrow ring can more easily become trapped once retracted.
Causes
- forgetting to return the foreskin after cleaning, bathing or urinating
- after sexual activity or masturbation
- after a medical exam, cystoscopy or urinary catheter insertion (especially in hospitals and nursing homes)
- forcibly retracting a child's foreskin before it is ready
- inflammation or infection (balanitis)
- genital piercings
- genital injury
Symptoms
- foreskin stuck behind the glans
- painful swelling of the glans and the foreskin (see penis pain for other causes)
- a tight band just behind the head of the penis
- redness or discoloration of the glans
- difficulty passing urine
- in young children: crying, irritability, refusing to urinate
If blood flow is compromised, the glans can turn dark or bluish, which is a sign of serious danger.
What not to do
- Do not wait to see if it settles; swelling usually worsens over time.
- Do not apply heat.
- Do not cut the foreskin yourself.
A gentle attempt to slide the foreskin forward after applying a cold pack (wrapped in a cloth) for a few minutes is reasonable on the way to care, but do not force it.
Treatment
Paraphimosis is treated in the ER or by a urologist. Pain relief is given first, often with a local anesthetic block or numbing gel.
Reducing swelling
- manual compression: squeezing the glans firmly for several minutes to push fluid out
- ice wrapped in a glove or cloth
- elastic compression wrap for a few minutes
- sugar or osmotic agents placed on the swollen tissue to draw out fluid
- small needle punctures to release fluid in some cases
Manual reduction
The clinician pushes the glans back with the thumbs while pulling the foreskin forward with the fingers. This works in most cases.
Procedures
If manual reduction fails:
- dorsal slit: a small cut in the tight band of foreskin under anesthesia to release it
- emergency circumcision in rare cases
After treatment
- swelling settles over a few days
- keep the area clean; antibiotics are given only if infected, for example with a urinary tract infection
- circumcision is often recommended later to prevent recurrence, especially with phimosis or repeated episodes
Complications
Prompt treatment usually prevents problems. Delay can lead to:
- infection
- damage or death of tissue of the glans (very rare with timely care)
- scarring of the foreskin
Prevention
- always return the foreskin to its normal position after cleaning, urinating, sex and medical procedures
- caregivers in hospitals and care homes should check and reposition the foreskin after catheter insertion or care
- do not forcibly retract a young boy's foreskin; it separates naturally over years
- treat phimosis and balanitis
Frequently asked questions
What is paraphimosis?
Paraphimosis is when the foreskin is pulled back behind the head of the penis and cannot be returned, causing painful swelling. It is a urologic emergency because the swelling can cut off blood flow to the head of the penis.
What should I do if my foreskin is stuck?
Go to the emergency room promptly. On the way, you can apply a cold pack wrapped in a cloth and gently try to slide the foreskin forward, but do not force it. Doctors reduce the swelling and return the foreskin, sometimes with a small procedure.
What is the difference between phimosis and paraphimosis?
Phimosis is a foreskin that is too tight to pull back over the head of the penis. Paraphimosis is a retracted foreskin that cannot be returned forward. Phimosis is usually not urgent; paraphimosis is an emergency.
Can paraphimosis happen again?
Yes, especially if the foreskin is tight. Returning the foreskin forward after every retraction helps prevent it. If it recurs or phimosis is present, doctors often recommend circumcision.
How is paraphimosis treated in the ER?
After pain relief, the clinician reduces swelling with compression, ice or other methods, then manually pushes the foreskin back into place. If that fails, a small incision (dorsal slit) releases the tight band.
