| PURPOSE : To investigate the usefulness of maximal blood flow volume (MBFV) measured by duplex ultrasonography
(US) compared with penile tumescence measured by RigiScanⓇ in the diagnosis of arteriogenic erectile
dysfunction (ED).
MATERIALS and METHODS : This study included twenty six patients who performed both RigiScanⓇ and duplex US
after intracorporeal injection of Prostaglandin E1. We measured tumescences of penile tip and base using
RigiScanⓇ, and maximal arterial diameter (MAD) and peak systolic velocity (PSV) using a 7 MHz. color
Doppler unit. MBFV was defined as (MAD/2)2×π×PSV. Based on normal value, we compared MAD and
MBFV, and PSV and MBFV and the correlations of each measurements were evaluated with Spearman’s correlation
analysis. The level of significance was P < 0.05.
RESULTS : The results between MAD and MBFV, and PSV and MBFV based on normal values were similar, respectively.
Tumescences of penile tip and base were significantly correlated with MAD (r = 0.409, r = 0.52, p <
0.05), and with PSV (r = 0.565, r = 0.396, p < 0.05). MBFV was also significantly correlated with tumescences
of penile tip and base (r = 0.502, r = 0.563, p < 0.05). In 4 patients with abnormal MAD and normal PSV, 3 had
abnormal MBFV and 1 had normal MBFV. All 3 patients with abnormal MBFV had abnormal penile tumescence
and 1 patients with normal MBFV had normal tumescence. One patients with normal MAD and abnormal
PSV had abnormal MBFV and penile tumescence.
CONCLUSION : In our study, MBFV was accurate in the diagnosis of arteriogenic ED. Moreover, MBFV was usefulness
in the diagnosis of arteriogenic ED as it could explain th e cases where MAD and PSV are not accorded. |
