The noninvasive diagnosis of XXXX .

@entity1 @entity323 @entity11539
One hundred eleven impotent @entity1 and 25 potent @entity1 were prospectively evaluated with a standardized exercise treadmill test (SETT) used to noninvasively define their pelvic hemodynamics. Fifty-six @entity1 had @entity11539 , whereas the remaining 55 had @entity323 resulting from undetermined causes (31), psychogenic factors (10), or other identifiable reasons (14). Arteriography was performed on 40 (71%) of the @entity1 with @entity11539 without false positive results, as well as in 11 (44%) of the potent control @entity1 and in six (11%) of the @entity1 with nonvasculogenic @entity323 without false negative results, confirming the validity of the SETT. The distinction between vasculogenic and nonvasculogenic @entity323 can be accurately made with the SETT. @entity1 with @entity11539 had a resting penile-brachial index (PBI) equal to 0.60 +/- 0.022 (mean +/- SEM) and a PBI after exercise equal to 0.45 +/- 0.019 with a fall in the mean PBI of -0.15 (p less than 0.001). @entity1 with nonvasculogenic @entity323 had a resting PBI equal to 0.80 +/- 0.024 and a PBI after exercise equal to 0.88 +/- 0.019 with a rise in mean PBI of 0.08 (p less than 0.001). This response was not significantly different between the control group and the nonvasculogenic @entity323 @entity1 . The addition of PBI determinations after treadmill exercise revealed that 18% of the @entity1 with @entity11539 would have been incorrectly diagnosed, because their resting PBI was greater than the traditional standard of 0.70. Furthermore, 18% of the @entity1 with nonvasculogenic @entity323 would have been incorrectly diagnosed as having @entity11539 because their resting PBI was less than 0.70.(ABSTRACT TRUNCATED AT 250 WORDS)
