Introduction:
Management for distal impending erosion can be difficult and has been previously managed with counter incisions which can lead to unsightly scars and increased infection risk.
Aim:
To demonstrate a novel technique in management of impending erosion.
Methods:
We retrospectively reviewed patients who underwent placement of a distal biologic cap for impending erosion.
Main Outcome Measure:
The main outcome was thesuccessful placement of inflatable penile prosthesis through a single incision.
Results:
All patients who underwent this procedure are functional and have had no evidence of recurrence.
Clinical Implications:
A simple approach to manage impending distal erosion.
Strength & Limitations:
Limitations include small sample size and short duration of follow-up.
Conclusion:
The distal biologic cap is a simple alternative technique to treat distal impending erosion of an inflatable penile prosthesis and can be performed safely without the need for additional incisions on the penis and with a minimal increase in operative times.
