Post-injection doppler waveforms obtained at 5, 10, 15 (two readings), 20 (three readings), and 25 minutes. Peak systolic velocity is consistently below 30 cm/sec. Visually, tumescence and partial rigidity was seen 15 min. after injection, however patient could not develop full rigidity or erection.
This case demonstrates role of penile doppler in arterial insufficiency.
