Peyronie's disease (PD) is a penile diseases which is characterized by penile pain, curvature, shortening and plaque in penis which usually end up into erectile dysfunction (ED).This study is to assess the efficacy of modified vacuum (Hamrah VCD, Hamrah medico-engg group, Tehran, Iran) therapy in patients with PD and ED .The basic principal of the study is similar to modelling performed during penile implant surgery .This study is performed on 43 patients with mean age of 56.3 years (40-74 years).Patients practiced with three different vacuum cylinder 30 minutes, 3 times a day for 3 months. First month the smallest cylinder, second month the medium cylinder and third month the biggest cylinder was used. Parameters recorded before the beginning of the study at the end of each month. Assessment includes number and size of plaque, angle of penile curvature (by erection induced with VCD), pain during erection, status of morning erection, quality of erection and various previous treatments. There was a clinically and statistically significant improvement in angle of curvature, size and numbers of plaque.
There was a significant reduction in plaque size and curvature. The mean of plaque size and curvature was 1.39 cm and 31.28 degrees respectively at presentation which was reduced to 0.64 (0-3) cm and 11.6 degree respectively at the end of study. At the end of the study 30 (69.7%) patients were satisfied with the outcome and wanted no further treatment .There was no major side effect observed in patients using the device. We recommend use of modified vacuum device with mentioned method for PD and ED with curvature less than 45 degree and plaque size less than 2 cm. It is safe to use in all stages of the disease and can help patients to attain erection with VCD.
