Objective: Previous experience in the treatment of plaque with hyperthermia in orthopaedics led the authors to investigate the effectiveness of this approach in patients with Peyronie's disease.
Patients and methods: The study population comprised 60 patients (aged 36-76 years) with advanced Peyronie's disease. Patients were divided into two groups (A and B), with 30 in each. Group A patients underwent local hyperthermia treatment, with 30-min treatment sessions twice a week for 5 weeks. Patients received a total of 10 applications, which reached a local temperature of 39-40 degrees C. A second cycle was repeated after a 1-month interval for a total of 20 treatment sessions. Group B patients were treated with intra-plaque infiltrations using 10 mg verapamil; they received one infiltration once a week for 3 months. Differences between the two groups, as well as between variables (before and after treatment), were analysed using Student t-test and Fisher test.
Results: Hyperthermia significantly reduced plaque size and penile curvature and led to an increase in mean scores of erectile function (EF) domain, while verapamil had no such effects. Haemodynamic parameters were not significantly modified in either group. Hyperthermia caused significantly fewer side effects than verapamil infiltrations and was significantly more effective in preventing disease progression. There were no significant differences between the two groups in terms of pain reduction during erection.
Conclusions: Results of this study stress the efficacy of hyperthermia in the treatment of advanced Peyronie's disease.
