Abstract:
Objective To assess the causes of erectile dysfunction (ED) after spinal or pelvic injuries.Methods From 2005 to 2009,a total of 67 patients who complained of ED after pelvic fracture or spinal injures were evaluated with the average patient age of 32 yrs (18 to 64) and average injury period of 38 mon (3 -144).Of the 67 patients,56 had pelvic fractures (84％) and 11 patients had spinal injures ( 16％ ).All patients reported normal erectile function before the injuries.All patients answered IIEF-5 and underwent nocturnal penile tumescence (NPT) tests (Rigiscan assessment system,continuing three nights).If resuls of the test were abnormal,color penile duplex ultrasound ( CDU ) with intracavernous injection were performed.Normal nocturnal erectile function was defined as at least three tumescence periods lasting more the 10 minutes with rigidity at the penile tip of at least 70％.Patients with abnormal nocturnal erectile function were diagnosed with organic ED.Patients who achieved a fully erect penis after intracavernous injection,and who had a peak systolic velocity ( PSV ) of less than 25 em/s on CDU were diagnosed with arterial ED.Patients with a PSV of more than 25 cm/s and an end diastolic velocity (EDV) of more than 5 cm/s on CDU indicated venous leakage.Patients with organic ED who had normal vascular function on duplex ultrasound were diagnosed with neurogenic ED.Results All patients reported IIEF-5 less than 8,NPT tests showed that all patients had organic ED.Of the patients with pelvic fracture,neurogenic ED,arterial ED and venous leakage was diagnosed in 24 patients (43％),22 patients (39％) and 10 patients (18％),respectively.However,the patients with spinal injuries were all diagnosed with neurogenic ED.Conclusions Pelvic fracture and spinal injury can cause organic ED.Vascular ED is common in pelvic fracture,however,neurogenic ED was the most common type of ED in spinal injury.
