Frequency of vasculogenic erectile dysfunction with color doppler sonography following intracavernosal injection of prostaglandin E1

Abstract

Objective: To determine the frequency of vasculogenic erectile dysfunction with color Doppler sonography following intracavernosal injection of prostaglandin E1.

Subject and Methods: 77 patients of erectile dysfunction who underwent color doppler sonography at department of diagnostic radiology, Liaquat National Postgraduate Medical Centre from December 2013 till November 2014 were enrolled in this study. The penile color doppler sonography was performed on Toshiba Aplio using 7MHz linear array probe following intracavernosal injection of prostaglandin E1 20mcg.

 RESULTS:  Vasculogenic erectile dysfunction was observed in 48(62.3%) cases. Out of 48 cases, arterial insufficiency was seen in 10(20.8%) and venous insufficiency was observed in 38(79.2%) cases. Rate of vasculogenic erectile dysfunction was significantly higher in 46 to 50 years of age.

Conclusion: In our study predominant cause of erectile dysfunction is vasculogenic which can be diagnosed efficiently by Color Doppler sonography following intracavernosal injection of prostaglandin E1.

Key Words: Vasculogenic erectile dysfunction, Color Doppler Sonography, prostaglandin E1.
