Effect of sildenafil on erectile dysfunction in spinal cord injured patients.

BACKGROUND Erectile dysfunction is a preoccupying issue, just like motor and bladder disability, in spinal cord injured (SCI) patients. This is particularly so because of the increasing prevalence of paraplegic and tetraplegic subjects and the fact that these patients are younger, and sexually active. OBJECTIVE To determine the effects of Sildenafil (Viagra((R))) on erectile dysfunction in SCI patients. METHODS After medical ethics committee approval and informed patient consent, we conducted a prospective inquiry between January and March 2007 in 16 SCI patients who were under Sildenafil treatment for erectile dysfunction. An abridged version of the International Index of Erectile Function (IIEF-5) questionnaire was completed the patients. RESULTS The mean age (range) of the patients was 32.75 yrs (21-53 yrs). The mean duration of their disability was 47.75 months (4 yr). Trauma was the etiology in 87.5% of the cases (44% were road accidents). 12/16 patients were paraplegics (10 above T10) and 4 were tetraplegics (1 above C4 and 3 below C5). The mean duration of sildenafil treatment was 18.75 months (17 days-7 yr). 70% of the patients were satisfied with their erection after treatment. However, 10/16 patients had concomitant treatment with alprostadil. CONCLUSION Sildenafil is a vasoactive drug which can be used as a simple, discrete and effective treatment for erectile dysfunction in SCI patients. This approach is compatible with the efforts to improve the quality of life and rehabilitation of these patients.
