Erectile dysfunction is very common at the age of above 40s. The previous studies from Taiwan revealed around 50% male had ED problem once before. The psychological or physiological aspects both influence pathway of tumecence and rigidity. Most of the patients had a lot of improvement from PDE5 inhibitors, such as Viagra, Cialis, Levitra. It seems that carvernosal artery plays a key role of tumecence. We evaluate the patients with ED who had examined peak systolic velocity(PSV) and end diastolic velocity(EDV).
Materials and Methods:
We review charts from patients of erectile dysfunction who had examined his penile blood flow status including PSV/EDV/RI. We also record his testosterone level, triglyceride and total cholesterol.
We had investigated five patients. The age ranges from 24 to 70 years old. The testosterone level ranges from 3.4ng/ml to 6.6ng/ml (1.75ng/ml~7.81ng/ml).
Peak systolic velocity after alprostadilintracoporeal injection range from 11.39ml/sec to 21.82ml/sec.
The penile blood flow from Doppler ultrasound is a very useful tool for evaluating erectile dysfunction.We think that penile blood flow evaluation as a routine examination for patient of erectile dysfunction.
