Urethral Injury and the Penile Prosthesis.
INTRODUCTION: The relative infrequency of urethral injuries during penile prosthesis implantation has caused the event to be understudied relative to the morbidity and cost associated with their management. AIM: To draw attention to both acute intraoperative and delayed urethral injuries via cylinder erosion by compiling and evaluating the available literature on their cause, diagnosis, and management. METHODS: A literature review was performed through PubMed from 1985 to 2018 regarding urethral injuries in the setting of penile prosthesis implantation. Comorbidities and anatomic factors that predispose a patient to a urethral injury were also queried. MAIN OUTCOME MEASURES: The goal is to identify at-risk populations and assess options for managing distal, mid-pendulous, and proximal acute urethral injuries that occur in the setting of penile prosthesis implantation. We also examine strategies to manage prosthesis erosion into the urethra. RESULTS: Although urethral injuries are rare, certain patient populations are at higher risk for the event. Injuries at various locations along the urethra present unique challenging and morbid clinical scenarios. However, there are a variety of management options available that allow a patient to ultimately void normally and have a successfully implanted penile prosthesis. CONCLUSION: Overall, penile prostheses offer many patients an improved sexual quality of life. In the setting of prosthesis implantation both acute and delayed urethral injuries are rare, but their associated morbidity can undercut the benefits of the device. Our understanding of these injuries has matured, and we now possess management strategies that can mitigate the morbidity and frustration that accompany this complication.
