Penile Prosthesis Surgical Techniques and Outcomes

Penile prosthesis implantation represents a definitive treatment for erectile dysfunction refractory to pharmacotherapy and vacuum devices. Techniques have evolved from simple semirigid rods to sophisticated three‐piece inflatable systems featuring a reservoir, pump and dual cylinders. Surgical approaches typically involve a penoscrotal or infrapubic incision, with meticulous corporal dilatation and reservoir placement to minimise risks of perforation or cross‐over. Advances in device design—such as antibiotic or hydrophilic coatings—have driven down infection rates, while refinements in cylinder engineering have enhanced mechanical reliability and reduced revision surgery. Patient satisfaction is generally high, reflecting restoration of sexual function and psychosocial well‐being, though complaints of penile length reduction and postoperative pain persist. Key outcomes encompass infection incidence, device survival over decades, functional efficacy, and quality of life metrics. Global audits reveal low intraoperative complication rates, and long‐term data suggest median device survival approaching two decades. Contemporary practice emphasises patient optimisation, standardised operative protocols and systematic follow-up to sustain high satisfaction and minimise adverse events.

Research from Nature Portfolio

Recent studies have characterised the microbial ecosystems that colonise explanted penile prostheses, revealing that nearly all devices harbour complex biofilms. Using next-generation sequencing and metabolomic profiling, researchers identified differential abundances of multiple bacterial genera and associated metabolites in asymptomatic versus infected devices. These findings suggest that transitions from colonisation to clinical infection are driven by shifts in microbe–metabolite interaction networks rather than by single pathogens alone. In vitro reconstitution of biofilms on materials such as silicone, polytetrafluoroethylene and titanium has provided a platform for mechanistic investigations and the development of targeted anti-biofilm strategies.

Technical terms

Biofilm: A structured community of microorganisms adherent to a surface, embedded in a self-produced matrix.

Inflatable Penile Prosthesis (IPP): A multi‐component device comprising cylinders, pump and fluid reservoir, allowing controlled penile rigidity.

Semirigid Penile Prosthesis (SPP): A malleable rod implanted within the corpora cavernosa, providing constant rigidity.

Device Survival Rate: The proportion of prostheses remaining functional without explant over a defined time period.
