Intracavernosal injection (ICI) therapy for erectile dysfunction (ED) carries a risk of corporal fibrosis, potentially making placement of an inflatable penile prosthesis more difficult. Prostate cancer treatment may also induce corporal fibrosis.


To assess whether a history of ICI or prostate cancer treatment is associated with complications following IPP placement.


A retrospective cohort study of primary IPP cases from 2016-2021 across 16 institutions. Patients were stratified by history of ICI and between-group differences in risk factors were assessed. Multivariable logistic regression was used to assess for predictors of intraoperative complications, postoperative non-infectious complications and postoperative infection.


A total of 2540 patients met inclusion criteria of which 781 (30.8%) had a history of ICI. Patients with a history of ICI tended to be older (mean 63 vs 64 years, p=0.002) and were more likely to have history of radical prostatectomy (21.0% vs. 32.1%, p<0.001) and/or radiation (5.51% vs 10.9%, p<0.001). On multivariable regression, a history of ICI, prostatectomy, and radiation were all significant predictors of intraoperative complications (OR 2.11, p=0.03; OR 2.27, p=0.03; OR 2.40, p=0.04, respectively). A history of ICI and patient age were predictors of non-infectious postoperative complications (OR 1.44, p=0.02, OR 1.02, p=0.004 respectively)). None of the variables were significant predictors of infection.


In men undergoing IPP placement, a history of ICI is associated with an increased risk of both intraoperative and postoperative, non-infectious complications. Prostate cancer treatment with radiation or surgery is independently associated with increased risk of intraoperative complications.
