“…For diagnosis of arteriogenic causes, color Doppler ultrasound is one of the most noninvasive, simple and promising tools [ 1 – 3 , 5 – 8 ]. The peak systolic velocity (PSV) of the cavernous artery measured after the intra-cavernous injection (ICI) of vasoactive agents is a widely accepted criterion for evaluating penile circulation [ 2 , 6 ].…”

BackgroundThis prospective study is to evaluate the potential value of sonographic measurements in the flaccid penis for the screening of arteriogenic impotence.MethodsA consecutive series of 260 Chinese males consulting for sexual dysfunction and 54 controls underwent sonographic examination. The sonographic parameters were correlated with the clinical gold standards, including the international index of erectile function (IIEF) and penile erectile hardness grading scale (EHGS). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the receiver operating characteristic curve (AUROC) of flaccid peak systolic velocity (PSV) in predicting patients with normal function were analyzed.ResultsThe mean cavernous PSV of both sides in the patients with sexual dysfunction ranged from 7.76 to 11.12 cm/sec with a stepwise increase in IIEF and EHGS grading scale (P < .05). The cutoff value of flaccid PSV for the differential diagnosis of grade 4 of IIEF-5 or EHGS was 8.20–8.90 cm/sec, with an AUROC of 0.657–0.724, specificity of 82.96–86.84% and PPV of 95.20–96.60%, respectively.ConclusionsThis simple flaccid PSV measurement is a specific tool for screening arteriogenic impotence.

“…In patients with severe Peyronie's disease, CSCs may represent blood leakage pathways at the level of the plaques which are responsible for distal penile flaccidity (13). CSCs can be recognized as collateral vessels feeding the fistula in patients with high-flow priapism as well (14).…”
