Urology (Prosthetic Urology Specialist)
A patient with an infected penile prosthesis should be referred to a urologist with expertise in prosthetic urology, as this is a specialized complication requiring device explantation or salvage procedures that demand specific technical skills and knowledge of infection management protocols.
Why Urology Specialization is Critical
Infected penile implants represent one of the most feared complications in prosthetic urology, occurring in 1-6% of primary cases and up to 18% in revision surgeries 1, 2. These infections require:
- Immediate surgical intervention (explantation or salvage procedures)
- Specialized knowledge of device-specific anatomy and surgical techniques
- Understanding of biofilm formation on prosthetic materials
- Expertise in salvage protocols to potentially preserve erectile function
The median time to infection management is approximately 1.8 months, with more than half requiring surgical intervention within 2 months of initial placement 3. This narrow window demands prompt recognition and referral.
Management Complexity Requires Subspecialty Expertise
The microbiology of penile prosthesis infections is complex and evolving. Common organisms include:
- Gram-positive bacteria (31.5% of cases, primarily Staphylococcus aureus)
- Gram-negative bacteria (22.2%, including E. coli and Pseudomonas)
- Fungal organisms (11.6%, particularly Candida)
- Anaerobes (4.2%)
- Culture-negative infections (30.6%) 3, 1
Recent next-generation sequencing data reveals that traditional cultures only detect the most abundant organism in 63% of cases 1, highlighting the diagnostic complexity that requires specialized interpretation.
Surgical Options Demand Technical Expertise
Management options include:
- Complete explantation with delayed reimplantation
- Immediate salvage procedures (Mulcahy salvage technique)
- Device replacement with aggressive antibiotic irrigation
These procedures require familiarity with:
- Antibiotic-coated devices
- Specialized irrigation protocols
- Management of scarred/fibrotic corpora 4
- Prevention of penile length loss
Common Pitfalls to Avoid
Do not delay referral while attempting prolonged antibiotic therapy alone—device infections rarely resolve without surgical intervention due to biofilm formation 5.
Do not refer to general surgery or infectious disease as primary consultants—while they may provide adjunctive support, the definitive management is surgical and device-specific.
Recognize high-risk patients who need immediate attention:
- Diabetics (HR 1.9 for infection) 1
- Patients with Peyronie's disease (OR 2.47 for reoperation) 6
- Active smokers (OR 2.75 for reoperation) 6
- Those with poor glycemic control (HbA1c >8, OR 2.25) 6
Timing is Critical
The evidence shows that conventional wisdom about "early" versus "late" infections should be abandoned—most infections present within the first 2 months and require prompt surgical management 3. Delays in referral to appropriate subspecialty care increase patient morbidity, risk of penile length loss, and potential for more extensive tissue damage requiring complex reconstruction 2, 4.
In summary: Immediate referral to urology (specifically a urologist experienced in prosthetic surgery) is mandatory for any suspected penile prosthesis infection, as these cases require specialized surgical expertise that cannot be adequately provided by other specialties.
