Phimosis, paraphimosis and circumcision
A non-retractile foreskin in a young boy is usually physiological and needs no treatment; pathological phimosis (scarring, lichen sclerosus, recurrent inflammation) is treated with steroid cream and, if needed, circumcision, and paraphimosis — a foreskin trapped behind the glans — is an emergency treated by immediate manual reduction.
Why it matters in the exam
The exam shows parents worried that their three-year-old's foreskin does not retract, or "ballooning" of the foreskin during voiding — neither is an indication for surgery. Natural separation of the foreskin from the glans continues throughout childhood, and by adolescence the foreskin usually retracts. Indications for treatment: a white circular scar at the tip of the foreskin, lichen sclerosus (BXO), recurrent balanoposthitis, recurrent urinary infections in a child with an anomaly, and difficulty voiding.
The first treatment for pathological phimosis is steroid cream (for example betamethasone 0.05 to 0.1 percent) twice daily for 4 to 8 weeks, with high success; when there is no improvement, or in lichen sclerosus, circumcision is performed. In an adult with new phimosis or recurrent balanitis it is important to check for diabetes. Chronic phimosis is a risk factor for penile cancer. Contraindications to neonatal circumcision: hypospadias, penile curvature, a "buried" or "webbed" penis, and a bleeding disorder — because the foreskin is needed for repair or the bleeding risk is high.
Paraphimosis usually follows catheter insertion or an examination after which the foreskin was not replaced, and the retracted foreskin forms a constricting ring with oedema of the glans. Treat at once: analgesia or a penile nerve block, prolonged compression of the oedema (possibly with ice or a compression bandage), and pushing the glans back while pulling the foreskin forward; if that fails — small punctures to drain the oedema or a dorsal slit, with circumcision later. An important rule for every team: after a catheter or examination, always replace the foreskin.
Key points
- Non-retractile foreskin in a child — usually normal.
- Pathological phimosis — steroid cream.
- Lichen sclerosus — circumcision.
- Paraphimosis — an emergency, immediate reduction.
- Hypospadias — a contraindication to circumcision.
Summary table
| Condition | Finding | Treatment |
|---|---|---|
| Physiological phimosis | Non-retractile foreskin, no scar, "ballooning" | Reassure parents, no treatment |
| Pathological phimosis | White scar, recurrent inflammation | Steroid cream 4 to 8 weeks |
| Lichen sclerosus | White scarred skin | Circumcision |
| Paraphimosis | Foreskin trapped behind the glans, oedema | Immediate manual reduction; dorsal slit if it fails |
| Contraindication to neonatal circumcision | Hypospadias, curvature, buried penis | Defer until repair |
