Treatment of childhood phimosis with a moderately potent topical steroid

Recently, topical steroid application has been shown by a small number of studies to be an effective alternative to circumcision for the treatment of phimosis. However, only potent or very potent corticosteroids have been more thoroughly studied in this treatment option. A prospective study was conducted to determine whether comparable results could be achieved using a weaker steroid cream.

Boys, 3-13 years of age, with non-retractable foreskin due to a tight ring at the tip were offered the regimen of twice-daily preputial retraction and topical application of 0.02% triamcinolone acetonide cream. The degree of preputial retractability was assessed at presentation and at 4 and 6 weeks of treatment. Success was defined as full retraction or free retraction up to agglutination of the foreskin to the glans.

Eighty-three boys completed the treatment. Successful retraction was achieved in 48/83 (58%) patients after 4 weeks and 70/83 (84%) patients after 6 weeks of application. The overall response rate aggregated from six published series using 0.05% betamethasone was 87% at 4 weeks and 90% on completion of treatment. Thus, the results appear inferior when analysed at 4 weeks but compare favourably with those reported for a more potent steroid on completion of the full course of treatment.

Even though the triamcinolone cream used in the present study is less potent than the more commonly used 0.05% betamethasone valerate cream, it could effect comparable improvements in foreskin retractability after 6 weeks of treatment.
