Infections of genitourinary prostheses

Area of Science:

• Urology
• Infectious Diseases
• Biomedical Engineering

Background:

• Penile prostheses and artificial urinary sphincters are medical devices used to treat conditions like erectile dysfunction and urinary incontinence.
• Infections associated with these devices, while uncommon, pose significant challenges to patient health and treatment outcomes.
• Understanding the pathogens and transmission routes is vital for effective management.

Purpose of the Study:

• To summarize the epidemiology, clinical presentation, and management of infections related to penile prostheses and artificial urinary sphincters.
• To highlight the common causative agents and routes of infection.
• To discuss current treatment strategies and the importance of preventative measures.

Main Methods:

• Literature review of documented cases and established clinical practices regarding device-related infections.
• Analysis of common bacterial pathogens, including Gram-positive (e.g., S. epidermidis) and Gram-negative enteric bacteria.
• Review of diagnostic signs, symptoms, and treatment modalities, including device explantation and salvage procedures.

Main Results:

• Infections typically occur during implantation or via hematogenous spread.
• Clinical signs can range from obvious to subtle, requiring careful diagnosis.
• While device removal is the standard treatment, successful salvage options exist.

Conclusions:

• Effective prevention of device infections relies on meticulous sterile techniques and appropriate antibiotic prophylaxis.
• Early recognition and management are essential for favorable outcomes in cases of prosthesis infection.
• Continued research into improved preventative strategies and less invasive treatments is warranted.
