We analyzed our colour Doppler ultrasound (CDU)studies performed for patients with various durations of priapismbefore and after therapeutic intervention.Methods: We reviewed 52 CDU studies for 24 patients with priapismbefore and after treatment for the period 1997\u20132007. Theduration of priapism ranged from 4 hours to 8 days. We performed17 CDU studies in 8 patients who presented with a duration ofpriapism of 7 hours or less, 9 studies in 4 patients who presentedwith duration of priapism of more than 20 hours, 23 studies in11 patients referred to us after they had failed prior therapeuticintervention at other institutions and 3 studies in 1 patient withpriapism related to perineal trauma.Results: Among the 8 patients who presented with a duration ofpriapism of 7 hours or less, CDU studies on presentation showeddetectible cavernosal arterial flow in all except 1 study. Amongthe 4 patients who presented with a duration of more than 20 hours,the studies showed no detectible cavernosal arterial blood flow.We repeated CDU studies after therapeutic intervention, and theyshowed restoration of cavernosal arterial flow with relief of venoocclusivestatus. Among the 11 patients in whom prior treatmentsfailed before they were referred to us, CDU studies performed onpresentation showed no detectible cavernosal arterial flow in 10of the 11 patients. We performed 12 CDU studies in 8 patientsafter placing a penile cavernosa-dorsal vein (CD) shunt. Weobserved the presence of blood flow in the CD shunt, indicatingits patency in all 8 patients. Some patients showed high cavernosalarterial flow (peak systolic velocity [PSV] up to 27.6 cm\/s) aftersurgery. These patients appeared to have residual priapism of primarilyarteriogenic status that improved after observation.Conclusion: After therapeutic intervention, CDU study is useful toassess the relief of arteriogenic and veno-occlusive status and thedecision for further treatment.Contexte : La litt\u00e9rature offre tr\u00e8s peu de renseignements sur lescaract\u00e9ristiques h\u00e9modynamiques du priapisme, en particulierapr\u00e8s une intervention th\u00e9rapeutique. Nous avons analys\u00e9 les donn\u00e9esprovenant d\u2019examens par \u00e9chographie Doppler en couleurs(\u00c9DC) men\u00e9s avant et apr\u00e8s une intervention th\u00e9rapeutique chezdes patients atteints de priapisme de dur\u00e9e variable.M\u00e9thodes : Nous avons pass\u00e9 en revue les donn\u00e9es de 52 examenspar \u00e9chographie Doppler en couleurs effectu\u00e9s avant et apr\u00e8s letraitement de 24 patients atteints de priapisme entre 1997 et 2007.La dur\u00e9e du priapisme variait entre 4 heures et 8 jours. Dix-sept\u00c9DC ont \u00e9t\u00e9 effectu\u00e9es chez 8 patients ayant pr\u00e9sent\u00e9 un priapismed\u2019une dur\u00e9e maximale de 7 heures; 9 \u00c9DC ont \u00e9t\u00e9 effectu\u00e9es chez4 patients ayant pr\u00e9sent\u00e9 un priapisme d\u2019une dur\u00e9e de plus de20 heures. Finalement, 23 \u00c9DC ont \u00e9t\u00e9 effectu\u00e9es chez 11 patientsqui nous avaient \u00e9t\u00e9 dirig\u00e9s en raison de l\u2019\u00e9chec de l\u2019interventionth\u00e9rapeutique ant\u00e9rieure dans d\u2019autres \u00e9tablissements. Trois \u00c9DCont \u00e9t\u00e9 men\u00e9es chez un patient atteint d\u2019un priapisme reli\u00e9 \u00e0 untraumatisme p\u00e9rin\u00e9al.R\u00e9sultats : Chez les 8 patients dont le priapisme avait eu une dur\u00e9emaximale de 7 heures, les \u00c9DC ont montr\u00e9 au d\u00e9part un d\u00e9bit sanguinperceptible dans l\u2019art\u00e8re caverneuse dans tous les cas sauf un. Surles 4 patients dont le priapisme avait dur\u00e9 plus de 20 heures, les examenspar \u00c9DC n\u2019ont montr\u00e9 aucun d\u00e9bit sanguin dans l\u2019art\u00e8re caverneuseau d\u00e9part. Les \u00c9DC ont \u00e9t\u00e9 r\u00e9p\u00e9t\u00e9es apr\u00e8s l\u2019interventionth\u00e9rapeutique et ont permis d\u2019observer un retour du d\u00e9bit sanguindans l\u2019art\u00e8re caverneuse avec soulagement de l\u2019occlusion veineuse.Chez les 11 patients qui n\u2019avaient pas r\u00e9pondu aux traitementsant\u00e9rieurs avant de nous consulter, les \u00c9DC effectu\u00e9es au d\u00e9part n\u2019ontmontr\u00e9 aucun d\u00e9bit sanguin perceptible dans l\u2019art\u00e8re caverneusedans 10 cas. Nous avons effectu\u00e9 12 \u00c9DC chez 8 patients apr\u00e8s uned\u00e9rivation veineuse dorso-caverneuse et avons observ\u00e9 la pr\u00e9senced\u2019un d\u00e9bit sanguin dans la d\u00e9rivation, montrant sa perm\u00e9abilit\u00e9 chezles 8 patients. Chez certains patients, on a not\u00e9 un d\u00e9bit sanguin\u00e9lev\u00e9 dans l\u2019art\u00e8re caverneuse (vitesse systolique maximale de27,6 cm\/sec) apr\u00e8s la chirurgie. Ces patients semblaient pr\u00e9senter unpriapisme r\u00e9siduel art\u00e9riog\u00e8ne primaire qui s\u2019est r\u00e9sorb\u00e9 par la suite.Conclusion : Apr\u00e8s une intervention th\u00e9rapeutique, les examens par\u00c9DC permettent d\u2019\u00e9valuer le soulagement des troubles art\u00e9riog\u00e8neset\/ou veino-occlusifs et d\u2019orienter le traitement subs\u00e9quent.<\/jats:p>","DOI":"10.5489\/cuaj.1125","type":"journal-article","created":{"date-parts":[[2016,10,11]],"date-time":"2016-10-11T11:44:27Z","timestamp":1476186267000},"page":"304","source":"Crossref","is-referenced-by-count":12,"title":["Colour Doppler ultrasound hemodynamic characteristics of patients with priapism before and after therapeutic interventions"],"prefix":"10.5489","volume":"3","author":[{"given":"Rei K.","family":"Chiou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Himanshu","family":"Aggarwal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher R.","family":"Chiou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fleur","family":"Broughton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3456","published-online":{"date-parts":[[2013,5,1]]},"container-title":["Canadian Urological Association Journal"],"original-title":[],"link":[{"URL":"http:\/\/www.cuaj.ca\/index.php\/journal\/article\/viewFile\/1125\/918","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.cuaj.ca\/index.php\/journal\/article\/viewFile\/1125\/918","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,9,11]],"date-time":"2017-09-11T15:50:19Z","timestamp":1505145019000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.cuaj.ca\/index.php\/journal\/article\/view\/1125"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,5,1]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2013,5,1]]}},"URL":"https:\/\/doi.org\/10.5489\/cuaj.1125","relation":{},"ISSN":["1920-1214","1911-6470"],"issn-type":[{"value":"1920-1214","type":"electronic"},{"value":"1911-6470","type":"print"}],"subject":[],"published":{"date-parts":[[2013,5,1]]}}}
