Abstract:
Aim: To study the effect of sodium nitroprusside (SNP) on the hemodynamics of corpus cavemosum in Chinese men with erectile dysfunction (ED). Methods: In 68 ED patients receiving intracavemous injection (ICI) of SNP, the cavernous hemodynamics were studied by Doppler ultrasonography. Results: The peak flow velocity (PFV), the artery diameter (Ad), the mean velocity of arterial blood (MV) and the vein diameter (Vd) were significantly higher after 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.
