Evaluation of impotent men with intracorporeal injection of papaverine and colour Doppler ultrasound.

Fifty impotent patients have been evaluated with intracorporeal injection of papaverine and colour Doppler ultrasound. The papaverine tests were negative in 34 of 50 patients. Nineteen of 34 patients with negative papaverine results showed normal colour Doppler findings. In 14 of 16 patients with positive papaverine results the colour Doppler analysis revealed normal structure and functions. Correlation between intracorporeal papaverine injection and colour Doppler ultrasound results was found in 59% (p < 0.01). We concluded that intracorporeal papaverine injection is an effective, simple diagnostic test for beginning evaluation of impotent men. However, this screening test should be supported by colour Doppler ultrasound.
