Three ultrasonographic diagnostic criteria of venous ED were applied. Criterion A: continuous blood flow signals in the deep dorsal vein, peak velocity greater than 3\u2009cm\/s, peak systolic velocity greater than 30\u2009cm\/s, end\u2010diastolic velocity greater than 5\u2009cm\/s; Criterion B: resistance index less than 0.89 and other parameters corresponding with Criterion A; Criterion C: resistance index less than 0.80 and other parameters corresponding with Criterion A.

Criterion A had the highest diagnostic accuracy, the largest area under the receiver operating characteristic curve (area\u2009=\u20090.811), and the highest consistency (kappa\u2009=\u20090.642) with the cavernosographic results in the 3 criteria.
