The foreskin: phimosis, balanoposthitis and circumcision
Tell a normal foreskin from disease, avoid unnecessary intervention, and know which child should see a pediatric urologist before circumcision.
Step 1 of 11
Objectives
After this course you will be able to
- Distinguish physiologic phimosis from pathologic phimosis.
- Explain the indications for topical steroid treatment and how to apply it correctly.
- Recognize balanoposthitis and paraphimosis and know the first-line management.
- Identify contraindications (hypospadias, buried penis, curvature) on examination before circumcision.
- Recognize early and late complications of circumcision.
Key message: a nonretractile foreskin in a young child is normal. Never force retraction, because it turns physiologic phimosis into scarred, pathologic phimosis.
Basics
Normal development of the foreskin
- ~96%nonretractile at birth
- ~50%retractile at 1 year
- ~90%retractile at 3 years
- ~1%still have phimosis at 16–17 years
At birth the inner surface of the foreskin is adherent to the glans. Accumulation of smegma, spontaneous erections and hormones gradually separate them. In some boys this process continues into adolescence and is normal.
Normal findings: ballooning of the foreskin during voiding (if there is no pain and no problem with the stream), white smegma "pearls" under the skin, mild adhesions. These need no treatment.
Basics
Physiologic vs pathologic phimosis
| Physiologic phimosis | Pathologic phimosis | |
|---|---|---|
| Age | Infancy and early childhood | Usually after 5 years |
| Preputial tip | Soft, pouts open like a "flower" on gentle traction | White, firm, scarred ring |
| Symptoms | Usually none | Pain, difficulty voiding, fissures, bleeding |
| Cause | Normal development | Lichen sclerosus (BXO), fissures from forced retraction, recurrent inflammation |
| Approach | Observation, hygiene | Topical steroid, often surgical treatment |
Lichen sclerosus (balanitis xerotica obliterans) appears as a white, shiny, firm scar at the preputial tip. It responds poorly to cream, and circumcision is the main treatment. It can spread to the meatus and urethra, so the child should be referred to a pediatric urologist.
Diagnosis
Examination and indications for treatment
On examination, retract the foreskin only gently and without pain: look at the preputial tip, whether the meatus is visible, and whether there is scarring.
Treatment is needed only in these situations:
- Recurrent balanoposthitis.
- Recurrent febrile urinary tract infection in a boy with a urinary tract anomaly (high-grade reflux, posterior urethral valves, dilated ureter).
- True voiding difficulty: thin stream, straining, urinary retention (not ballooning alone).
- White, scarred skin (suspected lichen sclerosus).
- Pain or skin splitting during erection in an adolescent.
Ballooning of the foreskin during voiding is not by itself an indication for treatment if the stream is normal and there is no pain.
Diagnosis
Balanoposthitis
Inflammation of the glans and foreskin. It occurs at least once during childhood in a few percent of uncircumcised boys, most often at 2–5 years.
- The most common cause is nonspecific irritation: soap, bubble bath, diapers, moisture.
- Bacterial (streptococcal, staphylococcal) and fungal (Candida) infection is less common.
- Treatment: warm water soaks 2–3 times a day, no forced retraction of the foreskin; antibiotic cream for bacterial infection, oral antibiotics in severe cases; antifungal cream for Candida.
- A swab can be taken if there is purulent discharge.
Balanoposthitis recurring several times a year is a medical indication for treatment of phimosis or for circumcision.
Diagnosis
Paraphimosis: an emergency
A tight foreskin is retracted behind the glans and does not return; the constricting ring causes edema, and as the edema increases, reduction becomes harder.
- Analgesia: topical anesthetic gel, analgesics as needed.
- Reduce the edema by squeezing the glans evenly with the fingers for 3–5 minutes; a cold compress helps.
- Push the glans back with the thumbs while drawing the foreskin forward with the index fingers.
- If this fails: reduction under general anesthesia or a dorsal slit of the constricting ring.
Always return the foreskin to its normal position after catheter placement or hygiene. In the hospital, one of the common causes of paraphimosis is failure to reposition the foreskin.
Treatment
Topical steroid treatment
- Indication: symptomatic phimosis.
- Agent: a medium-potency topical corticosteroid (for example, betamethasone 0.05–0.1% or mometasone 0.1%).
- Application: twice daily for 4–8 weeks, a thin layer applied only to the narrow tip of the foreskin.
- At the same time the skin is retracted very gently, without pain.
- Effect: the foreskin widens in about 80–90% of children.
- Without regular gentle retraction after treatment, the narrowing can recur.
Failure to respond to cream often points to lichen sclerosus or a thick scar. Such a child is referred to a pediatric urologist for surgical treatment.
Treatment
Before circumcision: who should not be circumcised?
Before circumcision the penis, meatus and testicles must be examined. In the following situations the foreskin may be needed for reconstruction, and the child is first referred to a pediatric urologist:
- Hypospadias, including children who look "born circumcised".
- Curvature without hypospadias (chordee) and penile torsion.
- Buried penis, webbed penis, megaprepuce.
- Suspected micropenis, ambiguous genitalia, hypospadias combined with an undescended testicle.
- A bleeding tendency in the child or the family.
A child with hypospadias should not be circumcised. The foreskin is used in the repair to cover the new urethra and to provide skin for the penis.
Treatment
Complications of circumcision
| Complication | Timing | What to do |
|---|---|---|
| Bleeding | Early, most common | Pressure for 10 minutes; surgical review if it does not stop |
| Infection | Early | Local treatment, antibiotics if spreading |
| Urinary retention | Early | Remove the dressing, urgent review |
| Meatal stenosis | Late, most common | Thin, upward-deflected stream; meatotomy |
| Skin bridges, adhesions | Late | Elective division |
| Too little or too much skin removed | Late | Individual assessment, revision |
| Trapped (concealed) penis | Late | Surgical correction |
| Urethral fistula, glans injury | Rare | Urgent referral to a pediatric urologist |
In the first 1–2 weeks after circumcision, a yellowish, moist coating on the glans is part of normal healing and should not be mistaken for pus.
Treatment
What to tell parents
- Do not force the foreskin back. Retract it gently only as far as it opens on its own, rinse with water, and always return it to its normal position.
- Avoid soap, bubble baths and scented products.
- Ballooning during voiding, white "pearls" and adhesions are normal.
- Have the child examined by a doctor before circumcision.
- If the foreskin is retracted and will not go back, seek medical care right away.
The pediatrician's role: explain physiologic phimosis as normal, prevent forced retraction, start topical steroid in symptomatic cases, identify contraindications before circumcision, and refer the child in pathologic cases.
Quiz
Quiz: Foreskin
Test yourself: choose one answer.
-
A 2-year-old boy has a nonretractile foreskin that balloons during voiding; the stream is normal, and there is no pain or infection. What should be done?
This is physiologic phimosis. Without symptoms no treatment is needed, and forced retraction causes scarred phimosis.
-
An 8-year-old has a white, shiny, firm ring at the preputial tip with no response to 8 weeks of topical steroid. What is the most likely diagnosis and next step?
A white, firm, scarred ring and no response to cream are typical of lichen sclerosus (BXO). Surgical treatment and assessment of the meatus/urethra are needed.
-
How is topical steroid applied for phimosis?
The cream is applied twice daily for 4–8 weeks only to the narrow tip of the foreskin, while the skin is retracted very gently.
-
Parents want their 6-month-old circumcised. On examination the urinary opening is on the underside of the glans and the foreskin is present only dorsally. What do you recommend?
This is distal hypospadias. The foreskin is needed for reconstruction, so circumcision is not done and the child is referred to a pediatric urologist.
-
What is the most common late complication of circumcision?
Meatal stenosis is the most common late complication of circumcision: a thin, upward-deflected stream and pain on voiding. It is corrected by meatotomy.
