Intracavernosal prostaglandin E1 self vs office injection therapy in patients with erectile dysfunction

Abstract

We have investigated the reliability of intracavernosal prostaglandin E1 (PGE1) office vs self-injection therapy in patients with erectile dysfunction (ED). A total of 298 male patients with ED were enrolled in this study. In all patients, intracavernosal titration of the PGE1 dose was performed. A total of 106 patients were enrolled in the self-injection program, and 192 patients were enrolled in the office injection program. There were significant differences between number of injections and amount of PGE1 per month, total number of injections, and total amount of PGE1 on office and self-injection programs (P < 0.05 for each). There was a significant increase in the dropout rate in the office injection group compared with the self-injection group (P < 0.05). There was an increase in penile fibrosis in the self-injection program compared with the office program (P < 0.05). A self-injection program is reliable. Office injection program can be reserved for a subset of ED patients with special preferences.
