Objective To identify comorbid conditions that may increase the likelihood of revision surgery after primary penile prosthesis implantation. To evaluate trends in utilization of prostheses and selection of device within the Veterans Affairs (VA) system. Methods A retrospective review of the VA Informatics and Computing Infrastructure database was performed using Current Procedural Technology codes to identify any Veteran who underwent penile prosthesis surgery between January 2000 and December 2013. Age, race, procedure type, and relevant comorbidities were identified and compared between groups. Results A total of 6586 patients underwent primary penile prosthesis placement with at least 1 year of follow-up. Peripheral vascular disease (P <.001), smoking (P <.001), hypertension (P = .012), and history of prostate cancer (P = .043) were each associated with a significant increased risk of revision or removal surgery. There was an increase in overall number of implants placed during the study and increased durability with malleable penile prosthesis (MPP), but there was a downward trend in the number of MPP placed relative to inflatable penile prosthesis (P <.001). MPP were more likely to be placed with increasing age (P <.05) and there was a trend toward increased MPP placement in African Americans compared with Caucasians (P = .06). Conclusion Peripheral vascular disease, hypertension, smoking, and history of prostate cancer are associated with increased risk for secondary surgery. This raises a provocative question of how vascular insufficiency may play a role in the likelihood of secondary surgery after penile prosthesis placement. Utilization of penile prosthesis placement in the VA system is steadily increasing, most notably with increased numbers of inflatable penile prosthesis placement.
