Preputioplasty (foreskin-preserving surgery): who it suits and what to ask

The name comes from prepuce, the medical word for the foreskin, and plasty, meaning reshaping. The aim is to open up the ring of tight skin that stops the foreskin sliding back, while keeping the foreskin itself. BAUS describes it in its circumcision leaflet as a procedure that widens the foreskin at its point of maximum tightness.

It sits within a group of foreskin-conserving options. The same BAUS leaflet names topical creams and washes, a dorsal slit of the foreskin, frenuloplasty (when the frenulum is tight) and preputioplasty as the alternatives to circumcision. The NHS adds that a procedure in which small cuts are made in the tip of the foreskin so it can be pulled back more easily is usually only suitable for children.

Preputioplasty and dorsal slit are related but not identical. BAUS describes the dorsal slit as a single cut along the length of the foreskin on top of the penis, stitched so the head is partially exposed, and says its cosmetic appearance is not as good as circumcision. Preputioplasty is aimed at widening the tight ring rather than leaving the head permanently exposed, which is why people who value appearance or wish to keep the foreskin sometimes ask about it.

A West Midlands referral guide for GPs, written by the Coventry and Rugby GP Gateway, describes the surgical choices for symptomatic phimosis as preputioplasty or circumcision, both usually done under local anaesthetic. This is a guide for a neighbouring area, so it is an example and not a statement about Birmingham services.

Preputioplasty is generally discussed for a foreskin that is tight at one point but otherwise healthy. It is less suited to a foreskin that is scarred throughout or affected by skin disease. The NHS lists scarring and tightness from conditions such as lichen sclerosus among the reasons circumcision may be needed, and the NHS lichen sclerosus page says that if the condition is severe a small operation to remove the foreskin may be needed.

BAUS adds that circumcision is usually the next step if topical treatment fails, and that circumcision may be needed after frenuloplasty or dorsal slit if problems persist. A surgeon who proposes preputioplasty should therefore explain the chance that circumcision is still needed later.

Evidence for preputioplasty in adults is limited in the sources reviewed for this guide, so no adult success figure is quoted here. The most detailed paper found was in children: Wilkinson and colleagues compared preputioplasty with an injection of triamcinolone into the skin against circumcision in boys with biopsy-proven BXO, a scarring skin condition of the foreskin and glans.

Of 136 boys, 104 chose preputioplasty and 32 circumcision. At a median follow-up of 14 months, 81% (84 of 104) in the preputioplasty group had a fully retractile foreskin with no visible BXO, and 13% (14 of 104) developed recurrent symptoms or BXO needing circumcision or a repeat preputioplasty. Narrowing at the urine outlet (meatal stenosis) occurred in 6% of the preputioplasty group against 19% of the circumcision group. The authors concluded most boys did well, with a small risk of recurrence.

This is a retrospective study of boys with one specific condition, not a trial in adults, so it should not be read as a promise for any individual. It does show why surgeons discuss recurrence openly.

Details vary by surgeon and technique, and the sources reviewed do not give a standard preputioplasty recovery timetable. For comparison, BAUS says that after circumcision the stitches are absorbable and usually disappear within two to three weeks, swelling lasts up to 7 to 14 days, and sexual activity should be avoided for four weeks or until the wound has healed. Ask your surgeon which of those timings apply to the procedure they are proposing.

A foreskin that has been widened still needs to be kept clean. The BAUS frenuloplasty leaflet advises retracting the foreskin daily after that operation to maintain the benefit, but only as far as is comfortable, and a surgeon may give similar instructions after preputioplasty. Whether and how often to stretch the foreskin is a point to confirm in writing.

On the NHS, a GP can refer to urology. The NHS says circumcision is only available for medical reasons, usually when other treatments have not worked. The Birmingham and Solihull ICB male circumcision policy page lists the medical situations in which circumcision is funded and does not name preputioplasty; whether a foreskin-preserving operation is offered locally is a question for the referring GP or the urology team.

If you consider paying privately, the questions below are worth asking. This guide does not recommend any clinic and gives no price, because none was found in a source suitable for quoting.

• Is the surgeon a GMC-registered doctor, and is the provider registered with the CQC?

• Which technique will be used, how many of this operation has the surgeon done, and what proportion later need circumcision?

• Is the anaesthetic local or general, and who gives it?

• Is the quote written and itemised, and does it cover follow-up and repeat surgery?

• What aftercare is expected, including any daily stretching, and who do I contact if there is bleeding or infection?

BAUS lists, for dorsal slit, swelling of the penis that may last 7 to 14 days (between 1 in 2 and 1 in 10 patients), dissatisfaction with the cosmetic result, infection (1 to 2%), bleeding needing a further procedure (1 to 2%) and the need for later removal of excess skin or circumcision. These figures belong to that operation, not to preputioplasty, but they illustrate the kind of risks to ask about.

After any foreskin surgery, the NHS says to ask for an urgent GP appointment or get help from NHS 111 if bleeding does not stop, the wound is red or warm, you have a high temperature, you find it very difficult to pee, there is blood in your pee, or your penis is very painful. Call 999 or go to A&E if you cannot pee at all.
