A Systematic Review of Literature Regarding Whether Immediate Preoperative Hemoglobin A1c or Serum Glucose Are Risk Factors for Infection Following Penile Prosthesis Implantation

Complications and troubleshooting in primary penile prosthetic surgery-a review

Penile implant surgery is the gold standard to treat erectile dysfunction with success rates of over 90%. The first penile implants were developed in the early 1900s. Since then, several types of implants have been developed including malleable implants, two-piece inflatable implants, and three-piece inflatable implants. The three-piece inflatable penile prosthesis, which was introduced in 1973, is the most widely used type of penile implant in the United States. Penile implant surgery has undergone numerous advancements over the years, improving outcomes and patient satisfaction. However, as with any surgical procedure, there are risks and complications associated with penile implant surgery. It is important for surgeons to understand these potential complications and to have strategies in place to manage and prevent them to achieve the best possible outcomes for their patients.

Penile implant surgery-managing complications

Penile prosthesis surgery represents the end-stage treatment for erectile dysfunction. It is conventionally used only in cases of erectile dysfunction refractory to pharmacological treatments or vacuum constriction devices. Contemporary literature suggests that penile prothesis surgery is associated with a high satisfaction rate and a low complication profile. However, it must be appreciated that the complications of surgery can have devastating consequences on a patient’s quality of life and satisfaction and include infection, prosthesis malfunction, penile corporal perforation and penile length loss. Several factors – such as appropriate patient selection, methodical preoperative assessment and patient optimization, specific intraoperative protocols and postoperative recommendations – can reduce the risk of surgical complications. This narrative review discusses the diagnosis and management of both intraoperative and postoperative complications of penile prosthesis surgery.

Practical Considerations in Inflatable Penile Implant Surgery

BACKGROUND

Penile prosthesis implantation remains an effective solution for men with medical-refractory erectile dysfunction (ED) following radical pelvic surgery. Despite the distortion of pelvic anatomy, a penile implant can be performed with excellent clinical outcomes provided strict patient selection, proper preoperative workup and safe surgical principles are adhered to.

AIM

To provide practical recommendations on inflatable penile prosthesis (IPP) implantation in patients with medical-refractory ED, with an emphasis on patient selection and counselling, preoperative workup as well as surgical considerations to minimize intraoperative complications.

METHODS

A Medline search on relevant English-only articles on penile prostheses and pelvic surgery was undertaken and the following terms were included in the search for articles of interest: "bladder cancer", "prostate cancer", "rectal cancer", "pelvic surgery" and "inflatable penile implant".

OUTCOMES

Clinical key recommendations on patient selection, preoperative workup and surgical principles.

RESULTS

Patients should be made aware of the mechanics of IPP and the informed consent process should outline the benefits and disadvantages of IPP surgery, alternative treatment options, cost, potential prosthetic complications and patient's expectations on clinical outcomes. Specialised diagnostic test for workup for ED is often not necessary although preoperative workup should include screening for active infection and optimising pre-existing medical comorbidities. Precautionary measures should be carried out to minimise infective complication. Corporal dilation and reservoir placement can be challenging in this group, and surgeons may require knowledge of advanced reconstructive surgical techniques when dealing with specific cases such as coexisting Peyronie's disease and continence issue.

CLINICAL TRANSLATION

Strict patient selection and counselling process coupled with safe surgical principles are important to achieve excellent linical outcomes and patient satisfaction rates.

STRENGTHS AND LIMITATIONS

This masterclass paper provides an overview of the practical considerations for men who are undergoing IPP surgery following radical pelvic surgery. Limitations include the lack of highquality data and detailed surgical description on each surgical troubleshooting steps for various prosthetic-related complications.

CONCLUSION

The IPP implantation can be performed efficiently and safely in patients following radical pelvic surgery. Chung E, Mulhall J. Practical Considerations in Inflatable Penile Implant Surgery. J Sex Med 2021;18:1320-1327.
