Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Men undergoing 3-piece penile prosthesis placement under general anesthesia at Mayo Clinic - Rochester.
  • ≥ 18 years old.

  • Current anti-platelet or anti-coagulation therapy with plans to continue at the time of prosthesis placement.
  • Poorly controlled diabetes mellitus (defined as HgbA1c > 8.5 within 30 days of surgery).
  • Concurrent adjunctive operative procedures planned at the time of penile prosthesis placement (examples: male urethral sling, Peyronie’s disease straightening with penile plication or incision/grafting).
  • Concurrent non-prosthetic surgery planned at the time of penile prosthesis placement (examples: circumcision, hernia repair, hydrocelectomy, etc.).
  • Planned infrapubic or subcoronal incision at the time of penile prosthesis placement.
  • Patients who will be undergoing prosthesis placement using local, monitored, or spinal anesthesia (i.e., non-general anesthesia).
