Comparison of the Effect of Steroids on the Treatment of Phimosis according to the Steroid Potencies.

PURPOSE: This study aimed to evaluate the outcomes of topical steroid therapy according to potency as the first-line treatment for boys with symptomatic phimosis.

MATERIALS AND

METHODS

From April 2017 to March 2019, we retrospectively reviewed 45 boys with severe phimosis (Kikiros retractability grade 4 or 5) who presented with phimosis-related complications. During the first year of the study period, methylprednisolone aceponate (MPA, Advantan®, potent topical steroid) was administered in 24 boys. Hydrocortisone butyrate (HCB, Bandel®, moderately potent topical steroid) was administered in 21 boys in the subsequent period. Topical steroids were administered for 4-8 weeks in all patients. Success of the therapy was determined by two conditions at 3 months after therapy: achieving Kikiros grade 3 and less with disappearance of symptoms.

RESULTS

Of 45 boys, 35 (77.8%) achieved success of the therapy. Mean age was 46.64±22.42 months. Recurrence of phimosis with clinical complications was confirmed in three of 35 patients with initial success (8.6%) during the follow-up period. All boys with recurrence showed remission after additional topical steroid therapy. Success rate of the MPA group was higher than that of the HCB group (91.7% and 61.9% respectively, P = .029). Side effects associated with the topical steroid application were not observed in all children.

CONCLUSION

Topical steroid application is an effective and safe procedure as first-line treatment in symptomatic boys with severe phimosis. Moreover, the potency of topical steroids for the treatment of phimosis is considered a factor affecting the success rate.
