Hospital-based trends in penile prosthetic surgery

Area of Science:

• Urology
• Andrology
• Health Services Research

Background:

• Examined national and regional trends in hospital-based penile prosthetic surgery.
• Identified patient-specific factors influencing the choice between inflatable and semi-rigid penile prostheses.

Purpose of the Study:

• To enhance understanding of surgical treatments for erectile dysfunction (ED).
• To analyze trends in penile implantations and factors affecting prosthesis selection.

Main Methods:

• Utilized the Nationwide Inpatient Sample (NIS) and California OSHPD database (1995-2010).
• Analyzed total penile implants, proportions of inflatable vs. semi-rigid prostheses.
• Performed multivariate analysis to identify factors associated with prosthesis type selection.

Main Results:

• Nationwide penile prosthetic surgeries decreased from 4,703 to 2,338 annually (NIS).
• Inflatable prostheses had higher costs but similar length of stay (LOS).
• Caucasian race, Peyronie's disease, and private insurance were associated with inflatable prostheses; this trend was also observed in California.

Conclusions:

• Hospital-based penile prosthetic surgery has seen a substantial decline nationwide and in California.
• Patient demographics and insurance status influence the selection of inflatable penile prostheses.
• California data aligns with national trends, supporting its use for studying ED surgical management.
