Morphodynamic Assessment of Penile Circulation in Impotent Patients: The Role of Duplex and Color Doppler Sonography

摘要: Duplex and color Doppler sonography were used to assess the vascular status of 240 impotent patients. The tests performed before after intracorporal injection a standard dose vasoactive mixture measurements done both at crura midshaft penis. Particular care was taken in evaluation cavernosal arteries diameter, wall pulsatility, morphology spectral waveform, blood flow acceleration, systolic diastolic velocity volume. Resistance pulsatility indexes also measured. Flow along deep dorsal vein quantified when possible. Cavernosal artery peak velocity, volume acceleration best indicators arterial penile circulation. Persistently elevated (> 10 cm/s) positively correlated with diagnosis venogenic impotence obtained by dynamic infusion cavernosometry—cavernosography almost 80% cases. Doppler...
