Iontophoresis for treatment of Peyronie's disease.

PURPOSE: We evaluate the efficacy of iontophoresis of dexamethasone, lidocaine and verapamil to treat Peyronie's disease.

MATERIALS AND METHODS: In an uncontrolled prospective study 100 unselected patients with Peyronie's disease were treated with 3 weekly courses of iontophoresis. The drug mixture was administered by an electrical current of 5 mA. and a self-adhesive receptacle fixed to the penile skin overlying the plaque.

RESULTS: Resolution of pain was observed in 96% of patients, plaque diminution in 53% and improvement of penile deviation in 37%. Impaired sexual function was improved in 19 of 43 patients (44%). The benefit of iontophoresis therapy was more pronounced in patients with a short history of disease. Because of lack of side effects and painless administration iontophoresis was well tolerated and accepted by all patients.

CONCLUSIONS: Iontophoresis of dexamethasone, lidocaine and verapamil may be regarded as first line nonsurgical treatment for Peyronie's disease.
