Dr. Gabriele Antonini, a renowned urologist and andrologist, successfully performed a complex Cross Over surgery for a malleable penile prosthesis, correcting an incorrectly implanted cylinder placement. The procedure required an expert abdominal incision to remove the mispositioned cylinders and subsequently reimplant them correctly, ensuring an optimal outcome for the patient. This operation represents a significant solution for cases of improper prosthetic implantation, showcasing Dr. Antonini’s high level of technical expertise and precision in urological prosthetic surgery.
