Aim: To study the effect of sodium nitroprusside (SNP) on the hemodynamics of corpus cavemosum in Chinese menwith erectile dysfunction (ED). Methods; In 68 ED patients receiving intracavemous injection (ICI) of SNP, thecavernous hemodynamics were studied by Doppler ultrasonography. Results: The peak flow velocity (PFV), theartery diameter (Ad), the mean velocity of arterial blood (MV) and the vein diameter (Vd) were significantly higherafter ICI of SNP than before ICI, but the end diastolic velocity (EDV) did not change significantly. Conclusion;The increase in Vd after SNP suggests that the venous outflow is not invariably decreased during penile erection.(Asian J Androl 2001 Dec; 3: 311 - 313)
