Inflatable penile prosthesis outcomes after pelvic radiation.

Area of Science:

• Urology
• Andrology
• Surgical Oncology

Background:

• Few studies have evaluated surgical outcomes of 3-piece inflatable penile prosthesis (IPP) in patients previously treated with pelvic radiation therapy (RT).
• Understanding complication rates is crucial for managing erectile dysfunction (ED) in cancer survivors.

Purpose of the Study:

• To compare surgical outcomes and complication rates of 3-piece IPP placement in patients with and without a history of pelvic RT.
• To assess the safety and efficacy of IPP in men with refractory ED following pelvic RT.

Main Methods:

• Retrospective analysis of 715 patients undergoing 3-piece IPP implantation (2007-2018).
• Comparison between 101 patients with pelvic RT exposure and 153 radiation-naïve controls (history of radical prostatectomy only).
• Analysis of surgical complications, comorbidities, and patient characteristics.

Main Results:

• Patients exposed to RT had higher BMI and Charlson co-morbidity index scores.
• Surgical complication rate was 18.4% in the RT group versus 11.5% in the control group (not statistically significant, p=0.141).
• Multivariable analysis indicated RT exposure was not significantly associated with increased complication risk (OR: 1.31; CI 0.55-3.12).

Conclusions:

• This study demonstrates no significant increase in surgical complication risk following 3-piece IPP placement in patients with a history of pelvic RT.
• The findings support the use of IPP as a viable treatment option for men with refractory ED after pelvic RT.
