Previous studies has shown that anterior urethroplasty negatively impact erectile function. Recovery of function is common but the likelihood and extent of recovery have not been fully elucidated.
Between October 2006 and May 2008 men undergoing anterior urethroplasty were enrolled in a prospective study at Northwestern University, Chicago to evaluate the effects of urethroplasty on erectile function. The International Index of Erectile Function was completed preoperatively and on all subsequent postoperative visits. Preoperative and postoperative erectile function was compared.
According to study conclusion anterior urethroplasty caused erectile dysfunction in approximately 40% of patients, although recovery was seen in most by 6 months. Bulbar urethroplasty appears to affect erectile function to a greater extent than penile urethroplasty, which may be explained by the proximity of the bulbar urethra to the nerves responsible for erection.
