Can an intracavernous papaverine injection be used to diagnose arteriogenic impotence?
We injected papaverine into the corpus cavernosum of 93 patients with impotence, and compared the results with findings from nocturnal penile tumescence monitoring, psychogenic erection monitoring after sexual stimulation, penile-brachial indexes, and dynamic cavernosography. There was a significant correlation between the findings from papaverine injection and dynamic cavernosography, but there was no correlation between the papaverine findings and other tests including the penile-brachial index. We conclude that we can disregard the possibility of venous abnormality in those who respond to papaverine injection, but we cannot disregard the possibility of arteriogenic abnormality. We proved that papaverine injection cannot diagnose arteriogenic abnormality.
