Peristalsis in the ureter partially forces the urine flow, along with hydrostatic pressure. Ureteral diseases and a double J stent, which is commonly inserted in a ureteral stenosis or occlusion, disturb normal peristalsis. Ineffective or no peristalsis could make the contour of the ureter a tube, a funnel, or a combination of the two. In this study, we investigated urine flow in the abnormal situation. We made three different, curved tubular, funnel-shaped, and undulated ureter models that were based on human anatomy. A numerical analysis of the urine flow rate and pattern in the ureter was performed for a combination of the three different ureters, with and without a ureteral stenosis and with four different types of double J stents. The three ureters showed a difference in urine flow rate and pattern. Luminal flow rate was affected by ureter shape. The side holes of a double J stent played a different role in detour, which depended on ureter geometry.<\/jats:p>","DOI":"10.1155\/2017\/5172641","type":"journal-article","created":{"date-parts":[[2017,6,4]],"date-time":"2017-06-04T17:02:34Z","timestamp":1496595754000},"page":"1-11","source":"Crossref","is-referenced-by-count":25,"title":["Analysis of Urine Flow in Three Different Ureter Models"],"prefix":"10.1155","volume":"2017","author":[{"given":"Kyung-Wuk","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Soongsil University, 369 Sangdo-Ro, Dongjak-gu, Seoul 156-743, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6094-0227","authenticated-orcid":true,"given":"Young Ho","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Seoul National University Boramae Hospital, 425 Shindaebang-2-dong, Dongjak-gu, Seoul 156-707, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung Bae","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Urology, Seoul National University Boramae Hospital, 425 Shindaebang-2-dong, Dongjak-gu, Seoul 156-707, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasutaka","family":"Baba","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hiroshima University Hospital, 1-2-3, Kasumi, Minami-ku, Hiroshima 734-8551, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyoung-Ho","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Soongsil University, 369 Sangdo-Ro, Dongjak-gu, Seoul 156-743, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang-Ho","family":"Suh","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Soongsil University, 369 Sangdo-Ro, Dongjak-gu, Seoul 156-743, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1177\/1756287210370699"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1089\/end.2009.0516"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.22.5.g02se081005"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1115\/1.2472381"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1093\/imammb\/dqn020"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s00285-003-0252-4"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0087433"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3233\/BME-151308"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.3233\/BME-151319"},{"key":"12","year":"1980"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/BF00717588"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2017\/5172641.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2017\/5172641.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2017\/5172641.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,4]],"date-time":"2017-06-04T17:02:37Z","timestamp":1496595757000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cmmm\/2017\/5172641\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":11,"alternative-id":["5172641","5172641"],"URL":"https:\/\/doi.org\/10.1155\/2017\/5172641","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
