The Plastibell ring: what to expect and when it comes away
The Plastibell is one of the commonest techniques used for circumcising newborn boys in the UK. Rather than stitching the wound, it relies on a plastic ring that stays in place for a few days and then drops off by itself. Knowing what is normal makes the week after the procedure much less worrying for parents.
How the Plastibell technique works
A clear plastic ring is placed over the head of the penis, under the foreskin. A ligature is tied around the foreskin in the groove of the ring, the excess foreskin is trimmed away, and the ring is left in position.
The ring compresses the skin so that it heals closed behind it. There are no stitches to remove. Local anaesthetic is used before the procedure, and sterile single-use instruments are standard.
The days after the procedure
The ring usually separates and falls off on its own within about three to seven days. It typically comes away in a nappy, so parents often do not see it happen.
It is common to see some swelling, a little crusting, and a small amount of yellow or white discharge around the ring. This discharge is part of normal healing, not automatically a sign of infection.
What parents should and should not do
The main rule is not to interfere with the ring. Pulling at it, or trying to hurry it along, risks bleeding and can damage the healing edge.
- Do not pull or twist the ring, even if it looks loose
- Keep the area clean and dry as the clinic instructs
- Change nappies promptly so the area is not left soiled
- Apply any ointment only if the clinic has told you to
- Do not forcibly retract the penis or the remaining foreskin
When to ask the clinic to look at it
Most Plastibell circumcisions heal without a problem, but contact the clinic or your GP if something does not look right. Ring-related problems include a ring that sticks or has not come away after about two weeks, and bleeding from the edge as the ring separates.
- The ring is still in place after about two weeks
- Bleeding that does not stop with gentle pressure
- Redness or swelling that spreads, or a temperature
- Pus with an unpleasant smell, or the area becoming increasingly painful
- Difficulty passing urine, or no wet nappies
Plastibell or open surgery?
The Plastibell is generally favoured for newborns because it avoids stitches and is quick. Older children and adults are usually treated with a conventional surgical technique instead, since the anatomy and healing requirements differ.
Which technique is suitable for your child is a clinical decision. Ask the clinic to explain which one they propose and why, and what aftercare that choice implies.
Common questions
What does the Plastibell ring look like as it heals?
A clear plastic ring sits just behind the head of the penis. As healing progresses it loosens, the skin edge closes behind it, and it eventually separates and drops off. Some crusting and a little yellow or white discharge around it are common.
What if the Plastibell ring has not fallen off after two weeks?
Contact the clinic. A ring that has not separated in that time may need to be removed by a clinician, and they will want to check the area is healing as expected.
Does the ring hurt when it comes off?
Most babies show little or no distress; it usually comes away in a nappy and is often not noticed. If there is bleeding that does not stop, or your baby seems to be in pain, seek advice.
Is the Plastibell used for adults?
It is generally used for newborns and babies. Older children and adult men are usually circumcised with a surgical technique instead, after an individual assessment.
