acute, painful, rigid shaft
compartment syndrom of the penis
Non-ischemic or high-flow priapism:
results from injury
painless, not fully rigid
rare in children
4
Q
Clinical Features
A
Fully rigid corpora cavernosa is indicative of ischemic priapism
5
Q
Workup
A
CBC, reticulocyte count, coagulation studies, hemoglobin
Electrophoresis if appropriate to work up underlying cause
Consider tox screen for drugs
