Air\u2010Charged catheters (ACC), one of the newer technologies for UDS pressure recording, has been adopted in growing numbers around the world for the past 15 years. Currently, there is a lack of published studies characterizing specific performance of the ACC. Since linearity, hysteresis, pressure drift, and frequency response are important components in characterizing accuracy for catheter\u2010manometer systems; this study aimed to assess these four aspects in ACC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 180 T\u2010DOC\u00ae ACC were used in three different laboratory settings to assess pressure linearity and hysteresis (15 dual\u2010sensor vesical and urethral and 30 single\u2010sensor abdominal), pressure drift over 2\u2009h (115 single\u2010sensor), and frequency response (20 single\u2010sensor). Data are presented as mean\u2009\u00b1\u2009standard deviation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>ACC showed linearity of 0.99\u2009\u00b1\u20090.01, 0.99\u2009\u00b1\u20090.01, and 1.01\u2009\u00b1\u20090.01; and hysteresis of 0.57\u2009\u00b1\u20090.3%, 0.76\u2009\u00b1\u20090.48%, and 1\u2009\u00b1\u20090.89% for the abdominal, vesical, and urethral sensors, respectively. A pressure drift of 2.2\u2009\u00b1\u20091.4% at 1\u2009h and 4.4\u2009\u00b1\u20092.5% at 2\u2009h were observed when compared to baseline pressures. The catheters did not show any amplification factor during the sweep from 1 to 30\u2009Hz, and recorded signals up to 5\u2009Hz attenuating higher frequency signals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In this study the T\u2010DOC\u00ae ACC showed a linear performance with minimal hysteresis associated with acceptable pressure drift, and adequate frequency response to capture clinically relevant pressures. The accurate results observed in this study suggest that these catheters are technically suitable to be used as a measuring instrument for UDS.<\/jats:p><\/jats:sec>","DOI":"10.1002\/nau.23342","type":"journal-article","created":{"date-parts":[[2017,7,17]],"date-time":"2017-07-17T12:32:37Z","timestamp":1500294757000},"page":"619-625","source":"Crossref","is-referenced-by-count":18,"title":["Performance analysis of the T\u2010DOC\u00ae air\u2010charged catheters: An alternate technology for urodynamics"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4021-6669","authenticated-orcid":false,"given":"Bruna M.","family":"Couri","sequence":"first","affiliation":[{"name":"Laborie Medical Technologies Mississauga Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie","family":"Bitzos","sequence":"additional","affiliation":[{"name":"Laborie Medical Technologies Mississauga Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deepak","family":"Bhardwaj","sequence":"additional","affiliation":[{"name":"Laborie Medical Technologies Mississauga Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Lockhart","sequence":"additional","affiliation":[{"name":"Laborie Medical Technologies Mississauga Ontario Canada"},{"name":"School of Engineering University of Guelph Guelph Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andy","family":"Yue","sequence":"additional","affiliation":[{"name":"Laborie Medical Technologies Mississauga Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ing","family":"Goping","sequence":"additional","affiliation":[{"name":"Laborie Medical Technologies Mississauga Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.12703\/P5-8"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11934-013-0361-6"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.3109\/03091908709062796"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.1930110102"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.22546"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.20991"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-004-1121-4"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-013-2182-z"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12938-016-0145-6"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.22827"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.21133"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.23124"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/1520-6777(1994)13:3<219::AID-NAU1930130303>3.0.CO;2-E"}],"container-title":["Neurourology and Urodynamics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fnau.23342","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/nau.23342","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T05:19:21Z","timestamp":1694668761000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/nau.23342"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,7,17]]},"references-count":13,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2018,2]]}},"alternative-id":["10.1002\/nau.23342"],"URL":"https:\/\/doi.org\/10.1002\/nau.23342","archive":["Portico"],"relation":{},"ISSN":["0733-2467","1520-6777"],"issn-type":[{"value":"0733-2467","type":"print"},{"value":"1520-6777","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,7,17]]}}}
