Abstract

We investigated the significance of dynamic pharmacocavernosometry and cavernosography with vasoactive agent during the evaluation of comprehensive vascular impotence study. Thirty patients investigated were involved under the impression of organic causes during comprehensive vascular impotence study after screening and noninvasive studies. The causes of impotence were venogenic 16, arteriogenic 7, venoeenic and arteriogenic 6 and neumeenic 1 case. The observed hemodynamic parameters were baseline intracavernosal pressure (ICP): P1(mmHg), ICP 10 minutes after injection of papaverint 45mg: P2(mmHg), ICP under perfusion ever the average systolic pressure: P3(mmHG), Induction Fliw Rate: IR(ml/min), Mainte-nance Flow Rate: MR(ml,min). Intial Decompression Rate: IDR(mmHg), steady state pressure: PSS (mmHg) and Intracavernosal resistance: R=(P3-P1)/MR (mmHg. min/ml). And caverno-sography was taken with 100 mmHg ICP for identification of leaking veins and the sites. There were complications of subcutneous hematoma in 2 cases and severe intracorporeal fibrosis in 1 case. In conclusion, dynamic pharmacocavernosometry is relatively objective method of venous incompetence evaluation, while cavernosography has the meaning to confirm the presence and site of leaking. So we can say that they have the role of reciprocal complement each other. But it has some invasive aspect and possibility of complications, so it is desirable to restrict to a part of comprehensive impotence study.
