To evaluate erectile dysfunction in patients with spinal cord injury and the relationship between patient's subjective answers and the results of objective tests regarding erectile dysfunction.
Twenty-one male patients with erectile dysfunction after spinal cord injury were administered with nocturnal penile tumescense and rigidity testing (NPTR) using Rigiscan over 2 consecutive nights. NPTR using Rigiscan at second night was performed after oral administration of sildenafil 50 mg. Answer of the global efficacy question (GEQ) after oral administration of sildenafil 50 mg and the parameters of NPTR were compared.
After oral administration of sildenafil 50 mg, number and duration of erectile episodes, and duration of rigidity greater than 60% on NPTR improved significantly (p< 0.05). Sixteen out of seventeen patients (94.1%) who showed improved nocturnal erection after oral administration of sildenafil 50 mg answered that they had an improved erectile function after sildenafil. All four patients (100%) who showed no improvement in nocturnal erection after sildenafil answered that their erectile function was not improved after oral administration of sildenafil 50 mg.
We expect NPTR using Rigiscan might be useful for the evaluation of erectile dysfunction in men with spinal cord injury. (J Korean Acad Rehab Med 2008; 32: 544-548)
