Penile prosthesis implantation is a well-established definitive treatment for erectile dysfunction that does not respond to pharmacologic or less invasive therapies. Contemporary devices offer high mechanical reliability and, in appropriately selected and counseled patients, some of the highest satisfaction rates in prosthetic surgery.
Device categories
- Inflatable prostheses. Two- and three-piece systems use fluid transfer from a reservoir to paired cylinders, producing a natural rigid-flaccid cycle. Three-piece devices provide the most physiologic result.
- Malleable (semi-rigid) prostheses. Bendable rods provide permanent semi-rigidity with a simpler mechanism, suited to selected patients including those with limited manual dexterity.
Mechanical reliability
Modern inflatable devices have improved markedly in durability through refinements such as kink-resistant tubing, reinforced connections, and coatings that reduce infection risk. Mechanical survival at multi-year follow-up is high, and revision most often relates to infection or, less commonly, mechanical failure of a component.
Patient selection and satisfaction
Careful patient and partner counseling about the mechanism, expected size, and realistic outcomes is the strongest predictor of satisfaction. Diabetic patients and those undergoing revision require attention to infection prophylaxis. Reported satisfaction rates are consistently high when expectations are aligned before surgery.
Reducing complications
Antibiotic-impregnated or hydrophilic-coated devices, meticulous sterile technique, and careful surgical handling reduce the principal complication of infection. Attention to cylinder sizing and reservoir placement minimizes mechanical and ergonomic issues.
