ObjectiveTo evaluate the results of nocturnal penile erection test and response to daily sildenafil in patients with erectile dysfunction (ED) due to pelvic fracture urethral disruption.MethodsFrom January 2010 to January 2012, we included 38 patients with ED due to pelvic fracture urethral disruption. The mean age was 33.1 years (range, 22-49 years). All were evaluated subjectively and objectively by the International Index of Erectile Function-5, nocturnal penile tumescence and rigidity (NPTR) test, and penile Doppler ultrasonography. Patients received daily sildenafil 50 mg for 3 months.ResultsThirty-one patients were followed up: 54.8% showed response to sildenafil defined as reporting successful vaginal penetration and intercourse. Patients with neurogenic, arterial, and venous EDs did not differ in efficiency rates (P = .587). However, the penile erectile rigidity recorded by NPTR test affected efficiency significantly (P = .046). Patients with tip rigidity >40% had the highest response rate (76.9%), but the response rate for patients with tip rigidity <20% was only 22.2%.ConclusionNPTR recording can reveal resident erectile function in patients with ED due to trauma and is significant for selecting pharmacologic treatment as optimal therapy.
