From the Guidelines
For a 16-year-old boy with smegma from phimosis, I recommend gentle cleaning with warm water and teaching proper hygiene techniques, along with a trial of topical steroid cream (betamethasone 0.05% or 0.1%) applied to the tight foreskin twice daily for 4-6 weeks as first-line treatment, as supported by the British Association of Dermatologists' guidelines 1. The patient should retract the foreskin only as far as comfortable during bathing, without forcing it.
- The topical steroid helps soften and stretch the foreskin tissue.
- The patient should also perform gentle stretching exercises of the foreskin during this period. If conservative management fails after 4-6 weeks, referral to a urologist is warranted to discuss other options including circumcision, as suggested by the guidelines 1. It's essential to reassure the patient that phimosis is common in adolescents and often resolves with conservative measures. The accumulation of smegma is a natural consequence of phimosis where normal skin cells and secretions cannot be properly cleaned away due to the inability to fully retract the foreskin. Proper hygiene and addressing the underlying phimosis will resolve the smegma issue, and the patient should be aware of the potential need for long-term follow-up to monitor for disease recurrence or complications, as outlined in the guidelines 1.
From the Research
Management of Phimosis in a 16-Year-Old Boy
- The condition of phimosis, where the foreskin cannot be fully retracted past the head of the penis, can be managed through various treatments, including topical corticosteroids 2, 3, 4, 5, 6.
- Topical corticosteroids, such as betamethasone and triamcinolone, have been shown to be effective in treating phimosis in boys, with success rates ranging from 67% to 95% 2, 3, 4, 6.
- A study comparing two treatment regimens of topical betamethasone found that both regimens were equally efficacious, with response rates of 84.5% and 87% 6.
- The use of topical corticosteroids may increase the complete resolution of phimosis after four to eight weeks of treatment, as well as the partial resolution of phimosis 5.
- Long-term follow-up has shown that topical corticosteroids may increase the long-term complete resolution of phimosis six or more months after treatment 5.
Treatment Options
- Topical corticosteroids, such as 0.05% betamethasone cream or 0.1% triamcinolone cream, can be applied twice daily for 4-8 weeks 2, 3, 4, 6.
- Manual retraction of the foreskin can be performed in conjunction with topical corticosteroid treatment 6.
- Circumcision may be necessary in cases where topical corticosteroid treatment is unsuccessful or in cases of severe phimosis 2, 3, 4.
Safety and Efficacy
- Topical corticosteroids have been shown to be safe and well-tolerated in the treatment of phimosis in boys, with few reported adverse effects 2, 3, 4, 5, 6.
- The efficacy of topical corticosteroids in treating phimosis has been demonstrated in several studies, with success rates ranging from 67% to 95% 2, 3, 4, 6.
