J Pak Med Assoc Jan ;56(6):258-61.

Objective: To assess the role of Color Doppler Sonography in the evaluation of erectile dysfunction. Methods: A cross-sectional study was conducted at the Radiology Department, Aga Khan University Hospital Karachi from 5-6-2002 to 2-9-2003. All consecutive patients presenting with erectile dysfunction and undergoing penile color Doppler evaluation with injection PGE1 20 mcg were included in this study. Results: A total of 70 patients with an age range of 24-70 years (mean 41± 12.25 years} were included in the study. A normal response was noted in 45 (psychogenic) cases. Vasculogenic causes were observed in 23 patients, 12 with arterial insufficiency and 11 with venous leak. Peyronie`s disease was diagnosed in 2 patients. Conclusion: Color Doppler evaluation of erectile dysfunction is an effective method for differentiating psychogenic and vasculogenic causes of erectile dysfunction (JPMA 56:258;2006).
