Figure 1.

Penile Doppler study in a patient with significant erectile dysfunction following an episode of prolonged ischaemic priapism. Upper images are greyscale longitudinal (left) and axial (right) images; note the echogenic, distorted cavernosa (arrow) reflecting significant corporal fibrosis. The lower image shows the Doppler assessment of the left cavernosal artery, revealing significantly reduced arterial flow (<10 cm s^–1). There was minimal response to pharmacostimulant injection. The study demonstrated extensive cavernosal fibrosis interfering with sinusoidal relaxation and subsequent poor arterial inflow.
