Introduction: Urethral trauma is often associated with erectile dysfunction (ED). Reconstructive surgery is complex and may impact negatively on sexual function.
Aim: The aim of this article is to investigate ED in patients with pelvic fracture urethral distraction defects (PFUDD) who underwent urethroplasty, and efficacy of treatment with sildenafil citrate.
Main outcome measures: A total of 41 patients with urethral stricture who suffered from PFUDD were assessed to exclude systemic diseases that may cause ED, such as hypertension, diabetes mellitus, heart disease, and chronic liver disease. The International Index of Erectile Function-5 was used as an evaluation tool. Assessments were made at three time points: the time of admission, two weeks after urethroplasty, and 3 months post-treatment with sildenafil.
Methods: Pharmacopenile duplex ultrasonography was used to examine blood flow of the cavernosum in order to distinguish arterial ED, venous ED, and nonvascular ED. All patients were treated with oral sildenafil, 100 mg once daily, three times a week, for 3 months.
Results: The incidence of ED following injury was 95.12%. There were no significant changes in scores following surgery. However, sildenafil had a success rate of approximately 81%, which appeared to be independent of age. Drug treatment seemed most effective for those with less severe ED at the outset. There was no significant difference in scores post-treatment between those who had vascular and nonvascular ED. Overall, the incidence of side effects due to sildenafil was 19.5%.
Conclusions: Urethral trauma is frequently associated with ED. Sildenafil citrate is useful in the drug treatment of ED in these patients and appears to be well-tolerated.
