Penile Pressures and Waveforms

Question 1

penile Doppler helps determine ___

Answer 1

whether an individual’s failure to attain or maintain a sufficient erection is related to peripheral vascular insufficiency

Question 2

penile/brachial index (PBI) results

Answer 2

normal ≥ 0.75
marginal 0.65-0.74
abnormal < 0.65

Question 3

pre-injection penile arteries are ___ resistance

Answer 3

high resistance

Question 4

post injection penile arteries are ___ resistance until full erection is obtained

Answer 4

low resistance

Question 5

penile PSVs increase after injection

normal:
marginal:
reduced:

Answer 5

normal > 30 cm/sec
marginal 25-29 cm/sec
reduced < 25 cm/sec

Question 6

deep dorsal venous flow velocities should not ___ post injection

Answer 6

should not increase

Question 7

deep dorsal venous flow velocities post injection

normal:
moderately increased:
markedly increased:

Answer 7

normal < 3 cm/sec
moderately increased 10-20 cm/sec
markedly increased > 20 cm/sec
