Does Diabetes Have a Negative Impact on Erectile Function Recovery After Radical Prostatectomy?

To quantify the risk of long-term post-radical prostatectomy (RP) erectile dysfunction (ED) in men with diabetes mellitus (DM). We included men who underwent RP and were followed for ≥24 months at our institution; men were excluded if they received androgen deprivation therapy or radiation therapy. Erectile function recovery (EFR) was assessed using the International Index of Erectile Function (IIEF) Erectile Function Domain (EFD) score pre-RP and serially during follow-up. We performed logistic regression analysis to investigate a potential association between erectile function 24 months post-RP. Of 2261 men included, 8% were diabetic. Men in the diabetic group tended to present with more vascular comorbidities. For men with DM, the median time from diagnosis was 4 years pre-RP, and the median hemoglobin A1c pre-RP was 6.7%. After 24 months post-RP, EFR was significantly lower among the diabetic group. The median EFD was 7. Men with DM had a lower proportion of functional EFR (17%) and a greater proportion of severe ED (57%). In the univariable logistic regression model to analyze DM diagnosis was a significant predictor of functional EFR (OR 0.43, P <.001) and severe ED (OR 1.85, P <.001) 24 months post-RP. Furthermore, this was not observed for a multivariable analysis. Twenty-four months after RP, EFR is compromised in individuals with DM. Copyright © 2024 Elsevier Inc. All rights reserved.
