PL 16. Multispiral computed pharmacocavernosography in the diagnosis of venoocclusive erectile dysfunction

Causes of surgical treatment failure for venoocclusive erectile dysfunction (ED) are not only the formation of new collaterals, but also the functioning of residual veins. Thereby, the search continues for a rational diagnostic method that provides an exception early clinical relapse.

Eighty-eight men with ultrasound signs of venous insufficiency of the penis were examined. The average age was 36.2 ± 9.6 years (18-56 years). The study performed on a multislice computed tomography "Toshiba Aquilion 64" Point of this study was induction of erection with PGE1 pharmacological control of haemodynamic response and the subsequent injection of non-ionogenic radiopaque vezipak 320 with saline solution in a 1:4 ratio. We used a protocol Pelvis HCT Native; 120 KV; 60 mA; Rot. Time 0,5; MPR and 3D reconstruction in the angiography programme. nous leakage was confirmed in 72 (81.8%) patients. At the proximal direction in 49 (55.7%), distal in 28 (31%), mixed in 11 (12.6%) patients. Of the total number of the patients: additionally revealed radiological signs of sclerosis of the corpora cavernosa in 19 patients (21.5%), structural changes in the tunica albuginea in Peyronie's disease in 1 (14%), clarified the status of the cavernous canals, urethra, and the integrity of the rigid and 3-component implants in 2 (2.28%). The sensitivity of this method was 98%, specificity - 96%.

Thus, dynamic cavernosography computer is a high-sensitive method of "second-line diagnostics" in determining the type of venoocclusive ED and identifying structural organic changes of the corpora cavernosa.
