Findings and procedure details
Exclude patients with erectile dysfunction due to other causes (neurological, psychological, arterial insufficiency, traumatic, toxic, metabolic)
After local sterilization, a 21G needle-cannula is inserted into the dorsal side of one corporus cavernosum and 20 mg of prostaglandin E1 are administered.
Erection degree is assessed using EHS score (erection hardness score).
Once the penis is fully erected (grades 3-4) , another 21G needle-cannula is inserted into controlateral corpus cavernosum, in which are then administrated 25-60 cc of contrast medium diluted (1/2) using Iomeprol and isotonic physiological solution, at an infusion rate of 2 mL/sec.
Three consecutive pelvis CT-scan (time 0, 5’ and 8’), from iliac crest up to perineum, including Penis, are acquired.
The images obtained are reconstructed employing two different reconstruction algorithms:
1. maximum intensity projection (MIP)
2. 3D volume rendering (3D-VR)
The patients is held under observation until the end of penile erection
