Phimosis in children: is surgery necessary?

|Dra. Giovanna Amador

Phimosis is the inability to fully retract the foreskin to expose the glans. It is a very common condition in boys and raises many questions for parents.

Is phimosis normal?

Yes, in the first years. At birth, the foreskin is naturally attached to the glans and does not retract. This is physiological phimosis and is completely normal. Over time, the foreskin gradually separates:

  • At one year: only 50% of boys have retractable foreskin
  • At three years: approximately 90%
  • At five years: virtually all

When does it become a problem?

Phimosis requires medical attention when:

  • Recurrent infections (balanitis): redness, swelling, and discharge from the foreskin
  • Difficulty urinating: the foreskin balloons out when urinating
  • Paraphimosis: the foreskin retracts but cannot return to its position (medical emergency)
  • Scarring phimosis: the edge of the foreskin has a white, rigid ring

Treatment without surgery

In many cases, phimosis is first treated with corticosteroid creams applied to the foreskin for 4-6 weeks, accompanied by gentle retraction exercises. This treatment is effective in 70-80% of cases.

When is surgery needed?

Circumcision or prepucioplasty is recommended when:

  • Cream treatment has not been effective
  • There are repeated infections despite treatment
  • There is scarring phimosis
  • There are episodes of paraphimosis

What is the surgery like?

Circumcision is outpatient and lasts about 30 minutes. Full recovery takes approximately 2-3 weeks. It is a safe and effective procedure with excellent results.

What parents should avoid

Never force foreskin retraction. This can cause pain, bleeding, and scarring that worsens phimosis. Retraction should occur naturally or with specialist guidance.

If you have any questions about your child's phimosis, consult a pediatric surgeon for proper evaluation.
