Databases reviewed contain de-identified data from the patient information form (PIF) that is typically) completed by representatives from American Medical Systems (AMS; Minnetonka, Minnesota) and Coloplast Surgical Urology (Coloplast Inc., Minneapolis, MN) at the time of prosthesis implantation. Occasionally the physician or operating room staff completes the form. Data for AMS was collected from January 1, 2006 to December 31, 2012, and for Coloplast from January 1, 2005 to December 31, 2012. The AMS database included only the 700 series inflatable device, while Coloplast data includes both malleable and inflatable devices. The PIFs include patient demographics and age, as well as place of implantation, surgical approach, etiology of ED (more than one may be selected) and device information. As with all of the information on the PIF, etiology of ED was determined by the physician performing the procedure. He or she was not limited in the number of diagnoses that could be selected. The ED etiology could only be categorized as "with" the diagnosis (selected on PIF) or "without" the diagnosis (not selected on PIF).

The AMS data included year of implantation, country of implantation, etiology of disease and surgical approach. The Coloplast data set included information on region and year of implantation. After acquisition, data was then grouped within Excel (Microsoft, Redmond, Washington).
