Abstract |
Vasculogenic impotence is produced by abnormalities of
vascular blood supply or drainage, and is the most
common cause of various organic impotences. An
increasing awareness of vascular causes of impotence
has resulted from development of various diagnostic
tests, but precise measurement of penile blood flow is
difficult. Radionuclidc penogram has been introduced
recently to diagnose vasculogenic impotence. Forty-one
impotent patients and 12 normal men were studied with
radionuclide erection penogram using Tc-99m
pertechnetate and an intracavernous injection of
papaverine. We defined arteriogenic impotence as
arterial index less than 0 66, and vcnogenic impotence
as venous index greater than 0.09. By this criteria,
the false positive ratio in normal men was 17% and the
false negative ratio in radically cystectomized
patients was 0%. Side effects were small purpura of the
penile shaft and dull pain during injection of
papaverine. The radionuclide erection penogram was
noninvasive and gave a dynamic evaluation of the
arterial supply, venous drainage, and blood flow in the
corporeal bodies. This method should be considered as a
valuable adjunct to evaluate patients with vasculogenic
impotence. |
