Intravenous pyelography and ultrasound were requested. Paired t test, &#x03C7;<sup>2<\/sup> test, Wilcoxon's rank sum test and correlation analysis were performed with a 95% significance level. <b><i>Results:<\/i><\/b> There were three distinguishing patterns of A-C: type I - detrusor contraction after the regular voiding phase, type II - detrusor contraction persisting after the flow rate had stopped, and type III - rebound of the detrusor contraction after the flow. A-C was observed in 13.9% of the women. Type I A-C wave patterns were present in 68 patients (11.8%), type II A-C wave patterns in 477 patients (83.2%), and type III A-C wave patterns in 28 patients (10.3%). Studies with intravenous pyelography and ultrasound very frequently showed bladder mucosa, muscle thickening or trabeculation. Secondary ureterectasis related to A-C waves was also observed. Additionally, watts factor, maximum flow rate, detrusor pressure and opening detrusor pressure were markedly elevated in patients with type III A-C, suggesting enhanced detrusor contraction in these A-C waves. <b><i>Conclusion:<\/i><\/b> A-C waves are a real urodynamic entity with different patterns of presentation and with clinical and morphological alterations.<\/jats:p>","DOI":"10.1159\/000360139","type":"journal-article","created":{"date-parts":[[2014,7,23]],"date-time":"2014-07-23T06:53:11Z","timestamp":1406098391000},"page":"431-436","source":"Crossref","is-referenced-by-count":6,"title":["Urodynamic After-Contraction Waves: A Large Observational Study in an Adult Female Population and Correlation with Bladder and Ureter Emptying Functions in Women"],"prefix":"10.1159","volume":"93","author":[{"given":"Paulo","family":"Rodrigues","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fl\u00e1vio","family":"Hering","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o Carlos","family":"Campagnari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2014,7,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.1930020306"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1464-410x.2000.00412.x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002\/nau.10052"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.1988.tb09158.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1046\/j.1464-410X.1996.19822.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1046\/j.1464-410X.2002.02827.x"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/nau.21061"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(05)68236-5"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1520-6777(1999)18:2<73::AID-NAU2>3.0.CO;2-X"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002\/nau.1930140404"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1002\/nau.1930130602"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(01)62686-7"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/360139","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/360139","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:27:54Z","timestamp":1745429274000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000360139"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":12,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2014,12,1]]},"published-print":{"date-parts":[[2014,12,23]]}},"URL":"https:\/\/doi.org\/10.1159\/000360139","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"type":"print","value":"0042-1138"},{"type":"electronic","value":"1423-0399"}],"subject":[],"published":{"date-parts":[[2014]]}}}
