John J. Mulcahy, MD

John J. Mulcahy, MD, Clinical Professor of Urology at the University of Alabama and the University of Arizona, discusses how urologic surgeons should place penile implant cylinders into scarred corpora cavernosa. He explains that the approach taken (either penoscrotal or infrapubic) should be the one with the fewest prior procedures, but notes that many urologists tend to favor one approach over the other. Dr. Mulcahy then discusses the surgical process he follows, from obtaining adequate exposure with a broad incision to selecting an appropriate corporotomy site. He also discusses the tools he finds most useful, including the Otis urethrotome for cutting corporal scar tissue.

Following the presentation, E. David Crawford, MD, Editor-in-Chief of Grand Rounds in Urology and Professor of Urology at the University of California, San Diego, conducts a Q&A session with Dr. Mulcahy. They discuss salvage protocols for prosthetic infections, as well as the role of new evaluation tools, such as next-generation sequencing, for identifying microbes and fungi.
