Male erectile dysfunction following spinal cord injury: a systematic review.
METHODS
Systematic review.


OBJECTIVE
To review sexuality in persons with spinal cord injuries (SCIs), and to report the effectiveness of erectile interventions.


METHODS
Reports from six databases (1966-2003), selected annual proceedings (1997-2002) and manufacturer's information were screened against eligibility criteria. Included reports were abstracted and data pooled from case-series reports regarding intracavernous injections and sildenafil.


RESULTS
From 2127 unique reports evaluated, 49 were included. Male sexual dysfunction was addressed in these reports of several interventions (behavioural therapy, topical agents, intraurethral alprosatadil, intracavernous injections, vacuum tumescence devices, penile implants, sacral stimulators and oral medication). Penile injections resulted in successful erectile function in 90% (95% CI: 83%, 97%) of men. Sildenafil resulted in 79% (95% CI: 68%, 90%) success; the difference in efficacy was not statistically significant. Five case-series reports involving 363 participants with penile implants demonstrated a high satisfaction rate, but a 10% complication rate.


CONCLUSIONS
A large body of evidence addressing sexuality in males focuses on erection. Penile injection, sildenafil and vacuum devices generally obviate the need for penile implants to address erectile dysfunction. Interventions may positively affect sexual activity in the short term. Long-term sexual adjustment and holistic approaches beyond erections remain to be studied. Rigorous study design and reporting, using common outcome measures, will facilitate higher quality research. This will positively impact patient care.
