Peyronie's disease: a study of its natural history and treatment with orthovoltage radiotherapy.

Followup data on 90 of 177 patients with Peyronie's disease seen from Janurary 1, 1950 to April 1, 1970 revealed that the ultimate outcome of the disease when not treated was no different from that following orthovoltage radiotherapy. The real benefit derived from orthovoltage radiotherapy appears to be that it hastens symptomatic improvement by 3 to 7 months. In 21 per cent of the patients there was an associated inflammatory joint or tendon disease, an association not previously reported.
