Placement of Inflatable Penile Implants in Patients With Prior Radical Pelvic Surgery: A Literature Review

Penile prosthesis for erectile restoration remains the only surgical option for medical refractory erectile dysfunction. Many expert prosthetic surgeons recommend special care when placing a reservoir in a patient who has undergone prior radical pelvic surgery (PRPS) due to distortion of anatomy and obliteration of the dead space in the traditionally used space of Retzius.

Review all the current literature on penile prosthesis implantation in patients with prior pelvic surgery, with an emphasis on tips and tricks for reservoir placement in this unique population.

A Medline PubMed search was used to identify articles of interest related to all topics surrounding pelvic surgery and penile prostheses. The following terms were included in the search for articles of interest: "bladder cancer," "prostate cancer," "rectal cancer," "colon cancer," "pelvic surgery," "penile implants," "penile implant reservoir," and "penile prosthesis." Articles were further screened for content and English language.

Outcomes and adverse event rates in this population. Review of options for reservoir placement.

The outcomes, satisfaction, and adverse event profiles are similar between patients in the PRPS group and those who are not, regardless of the cause for pelvic surgery. For surgeons uncomfortable with placing a reservoir in the compromised pelvis, a 2-piece inflatable penile implant (AMS Ambicor) is a viable option. For surgeons who recommend 3-piece implants in this patient population, alternative positions for the reservoir have been developed in the hope of avoiding catastrophic bowel, bladder, and vascular injuries.

In patients with PRPS, placing an inflatable penile prosthesis is not only feasible, it is definitive therapy with excellent patient satisfaction. Reservoir placement outside the space of Retzius or placing a 2-piece inflatable device can be easily performed with equivalent safety and efficacy. Madiraju SK, Hakky TS, Perito PE, et al.
