|
Objective: To evaluate the effect of oral sildenafil citrate (Viagra®) on erectile dysfunction following spinal cord injury.
Method: Seventy nine male patients with erectile dysfunction after spinal cord injury, who were free from contraindications, received 50 mg of sildenafil. Visual-analogue erection scale (VAES) was used to evaluate the rigidity of penis
before and
after the medication. In addition, the duration of erection and side effects of sildenafil were evaluated.
Results: Mean VAES score showed a statistically significant increase after the medication from 5.6 to 7.5 (p=0.000). The mean duration of erection also increased from 3.4 minutes to 27.1 minutes after medication (p=0.000). Sixty seven
patients
(84.8%) reported improved erection with 50 mg of sildenafil and sixty one patients (77.2%) reported rigid erection enough for sexual intercourse. Ten patients (12.7%) reported side effects: facial flushing (3), dizziness (2), headache (2), chest
pain
(2), and palpitation (1).
Conclusion: This study demonstrated that sildenafil is an effective medication in treating erectile dysfunction after spinal cord injury.
