Unfortunately, there is no standard procedure for CDDU conduction, a fact that results in high result-interpretation variability.  OBJECTIVE: The aims of this review are to promote greater standardization during CDDU of the penis and discuss the fundamental principles for its accurate conduction.  METHODS: CDDU is initially conducted with the penis in the flaccid state; the whole penis must be assessed (images at B mode) with a high-frequency linear transducer (7.5-18 MHz). Intracavernous injection of vasodilating agents (prostaglandin E1, papaverine, phentolamine) is performed to induce a rigid erection. Serial measurements at different times should be taken during the CDDU session and penile rigidity must be assessed in each evaluation.  RESULTS: It is important to monitor the erection response after the vasoactive agent (hardness scale), and scanning during the best-quality erection should be contemplated. Manual self-stimulation, audiovisual sexual stimulation (AVSS), and vasoactive agent re-dosing protocols must be taken into account to reduce the influence of psychogenic factors and to help the patient to get the hardest erection possible. Such measurements contribute to the maximal relaxation of the erectile tissue, so the hemodynamic parameters are not underestimated.  CONCLUSIONS: CDDU is a relevant specialized tool to assess patients with erectile dysfunction; therefore, this guideline will help to standardize and establish uniformity in its conduction and interpretation, taking into consideration the complexity and heterogeneity of CDDU evaluations of the penis.<\/jats:p>","DOI":"10.1590\/1806-9282.66.9.1180","type":"journal-article","created":{"date-parts":[[2020,10,1]],"date-time":"2020-10-01T18:50:00Z","timestamp":1601578200000},"page":"1180-1186","source":"Crossref","is-referenced-by-count":10,"title":["Standardization of penile hemodynamic evaluation through color duplex-doppler ultrasound"],"prefix":"10.1590","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5767-5867","authenticated-orcid":false,"given":"Felipe","family":"Carneiro","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0961-6966","authenticated-orcid":false,"given":"Osmar Cassio","family":"Saito","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3552-5400","authenticated-orcid":false,"given":"Eduardo P.","family":"Miranda","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2020,9]]},"reference":[{"issue":"3","key":"ref1","doi-asserted-by":"crossref","first-page":"777","DOI":"10.1148\/radiology.155.3.3890009","article-title":"Vasculogenic impotence evaluated by high-resolution ultrasonography and pulsed Doppler spectrum analysis","volume":"155","author":"Lue TF","year":"1985","journal-title":"Radiology"},{"key":"ref2","article-title":"EAU guidelines on erectile dysfunction, premature ejaculation, penile curvature and priapism","author":"Hatzimouratidis K","year":"2016","journal-title":"European Association of Urology"},{"issue":"4","key":"ref3","doi-asserted-by":"crossref","first-page":"298","DOI":"10.1038\/s41443-018-0074-y","article-title":"Penile duplex: clinical indications and application","volume":"31","author":"Patel P","year":"2019","journal-title":"Int J Impot Res"},{"issue":"3","key":"ref4","doi-asserted-by":"crossref","first-page":"197","DOI":"10.4081\/aiua.2014.3.197","article-title":"To evaluate the etiology of erectile dysfunction: what should we know currently?","volume":"86","author":"Celik O","year":"2014","journal-title":"Arch Ital Urol Androl"},{"issue":"7","key":"ref5","doi-asserted-by":"crossref","first-page":"2375","DOI":"10.1111\/j.1743-6109.2010.01841.x","article-title":"Diagnostic tests for male erectile dysfunction revisited.
