Glans Hypersensitivity in Ischemic Priapism
Glans hypersensitivity is NOT a characteristic feature of ischemic priapism—in fact, the glans typically remains soft and uninvolved in this condition. 1
Key Clinical Distinction
The hallmark physical examination finding in ischemic priapism is that only the corpora cavernosa are affected, while the corpus spongiosum and glans penis remain soft and flaccid. This is a critical diagnostic feature that helps differentiate ischemic from non-ischemic priapism 1.
What You Should Find on Examination:
- Corpora cavernosa: Fully rigid and tender
- Glans penis: Soft, NOT rigid, NOT hypersensitive
- Corpus spongiosum: Uninvolved and soft
This anatomical pattern occurs because ischemic priapism involves veno-occlusive dysfunction specifically within the paired corpora cavernosa, creating a compartment syndrome in these structures while sparing the glans and corpus spongiosum 1.
Clinical Implications
The absence of glans involvement is actually a diagnostic clue that helps confirm ischemic priapism. If a patient presents with:
- Rigid corpora cavernosa
- Soft glans
- Pain in the shaft (not glans hypersensitivity)
- Duration >4 hours
This pattern strongly suggests ischemic priapism and warrants immediate corporal blood gas analysis and intervention 1.
Common Pitfall to Avoid:
Do not confuse corporal tenderness/pain with glans hypersensitivity. The pain in ischemic priapism is typically described as corporal pain from the ischemic compartment syndrome affecting the cavernosa, not as glans sensitivity 1.
