Introduction:
There is no universal gold standard diagnostic test to differentiate psychogenic from organic erectile dysfunction (ED). Cavernosography/cavernosometry has been used to evaluate veno-occlusive dysfunction (VOD) in men with a proposed organic ED.
Aim:
To develop evidence-based guidelines for the performance and interpretation of cavernosography/cavernosometry.
Methods:
Review the methodology behind cavernosography/cavernosometry and evaluate the evidence that supports its use and interpretation of results.
Main Outcome Measure:
Expert opinion based on review of the literature, extensive internal committee discussion, public presentation, and debate.
Results:
The detailed technique of cavernosography/cavernosometry is described. An evidence-based perspective to the use and interpretation of cavernosometry is presented.
Conclusion:
The positive predictive value of cavernosometry still needs further assessment. It is unknown how many potent men would test positive for VOD (false positive).
