During the first 5 years after penile prosthesis implantation, complications such as malfunction requiring revision or replacement occur in only 7% of cases. We present a case of a 62-year-old patient who had a Coloplast Titan® prosthesis implanted while also undergoing girth enhancement corporoplasty. Shortly after, the patient noticed an increasing bulge on the side of his penis, which prevented total deflation. An aneurysm of the right cylinder was identified during reoperation; cylinders were replaced and the redundant tunica albuginea and septal defect were corrected by plication from inside the corpora cavernosa.
