Iranian researchers who studied men undergoing prostate surgery for benign prostatic hyperplasia (BPH) found that 12.5% of those without erectile dysfunction (ED) before surgery developed the condition postoperatively.
The incidence was 13.4% for who underwent transurethral resection of the prostate (TURP) and 11.25% for men who underwent open prostatectomy, according to researchers.
The study, by Mohammad Soleimani, MD, and colleagues at Shahid Beheshti Medical University in Tehran, included 246 BPH patients with a mean age of 63.7 years.
Men were considered to suffer from ED only if they had moderate to severe ED as determined using the five-item version of the International Index of Erectile Function.
The prevalence of preoperative ED was 24.6% and 25.9% in the TURP and open prostatectomy groups, respectively.
Risk factors for postoperative ED included hypertension, diabetes, higher cardiac risk index, older age, and higher transfusion rate, according to a report in the Scandinavian Journal of Urology and Nephrology (2009; published online ahead of print).
