Artificial perfusion in impotence

Pharmacocavernosography in the Evaluation of Erectile Failure

“…Most investigators use dynamic cavernosography, wherein the flow rates to achieve and maintain an artificial erection are measured [4,7], The reliability of this method is also contested, as it is not very physiological. A relaxation of the cavernous smooth muscles, which is essential for erection is not achieved [13,21], Cavernosography with simultaneous visual sex ual stimulation as reported by Ebbehoj et al [22] seems to be the most physiologically relevant investigative method for venous leakage. In the case of normal venous drainage, visual sexual stimulation leads to a definite cessation of the outflow of contrast material from the cavernous bodies, whereas in the situation of venous insufficiency venous outflow persists.…”

Hemodynamic Study of Penile Erection in Dogs

“…Artificial erection could be elicited in the human by high flow (20-120 ml/min) injection into the corpora cavernosa [2, [16][17][18], It is then maintained at a lesser flow rate once the cavernous sinuses are filled to their capacity. In animal studies, Lue et al [5,10] observed a 2.5-fold increment in internal pudendal arterial flow at the early phase of erection during both systolic and dia stolic phases, along with a 20 mm Hg decrease in internal pudendal arterial pressure.…”

Functional Evaluation of Penile Hemodynamics

“…Selective pharmacoangiography of the pelvis and penis was performed in 59 patients 4 and dynamic cavernosography 13,14 was done in 69. The correlation between the result of Doppler ultrasonography and angiography was 94.5 per cent.…”
