A propensity score-matched analysis of intra- and postoperative penile prosthetic complications in the solid organ transplant population.

Introduction: Solid organ transplant (SOT) has an anticipated higher risk of penile prosthesis (PP) complications related to immunosuppression and surgical approach post-SOT. It is still not determined if PP surgery in the SOT population incurs these same higher risks.

Objectives: To observe differences in intra- and postoperative PP complications between SOT and non-SOT cases from the TriNetX US Collaborative Network, a large real-world database of deidentified patient data from 56 health care organizations within the United States.

Methods: We used the TriNetX database to perform a propensity score-matched cohort study comparing 10-year outcomes between patients with and without a SOT (kidney, heart, lung, liver, pancreas, and intestine) who underwent a PP procedure. Cohorts were matched on age, race/ethnicity, history of pelvic and abdominal surgery, overweight and obesity status, type 2 diabetes mellitus, atherosclerosis, substance use disorders, socioeconomic difficulties, anticoagulant/antiplatelet medications, and spinal cord injury. Outcomes included intra- and perioperative complications as well as prosthetic complications (mechanical malfunction, fibrosis, displacement, hemorrhage, pain, stenosis, removal with or without replacement, and complex [all postoperative complications]).

Results: There were 233 patients in each group after matching (SOT and non-SOT). The mean ± SD age at the prosthesis procedure was 59.7 ± 9.89 years, and 44% of patients were White (P > .05). There was no significant difference for incidence of intra- and perioperative complications (2.62% vs 2.19%, P = .76). The SOT group did not have a higher 10-year incidence of complex complications (30.58% vs 27.51%, P = .11) or mechanical malfunction (10.35% vs 11.62%, P = .25) when compared with the non-SOT group. No difference was found for other prosthetic-related complications (P > .05).

Conclusion: In our analysis, patients with a SOT were not more likely to experience long-term complications related to PP. Surgeons performing PP surgery in the SOT population may consider this procedure a potentially safe and viable option for restoring erectile function.
