The sensitivity and specificity for the scanner, using the clinically desired value of a 400\u2010ml threshold, are 0.76 and 0.96, respectively. With a perfect classification for sensitivity at a 300\u2010ml threshold, specificity may drop to about 50%. Even using this cut\u2010off point, the number of women catheterised would be reduced by half compared to a procedure of catheterising all women at risk for postpartum urine retention diagnosed by clinical judgment alone. <jats:italic>Conclusion.<\/jats:italic> The ultrasound scanner is a reliable screening instrument for detecting PUR after vaginal birth.<\/jats:p>","DOI":"10.1080\/00016340701621478","type":"journal-article","created":{"date-parts":[[2007,9,23]],"date-time":"2007-09-23T02:18:32Z","timestamp":1190513912000},"page":"1251-1255","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Reliability of an automatic ultrasound system for detecting postpartum urinary retention after vaginal birth"],"prefix":"10.1111","volume":"86","author":[{"given":"MIRJAM","family":"LUKASSE","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HENRIK","family":"REN\u00c9 CEDERKVIST","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LEIV","family":"ARNE ROSSELAND","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,12,31]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000171863.57303.01"},{"key":"e_1_2_7_3_2","first-page":"960","article-title":"Early postpartum voiding dysfunction: incidence and correlation with obstetric parameters","volume":"49","author":"Groutz A","year":"2004","journal-title":"J Reprod Med"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016349709024608"},{"key":"e_1_2_7_5_2","first-page":"44","article-title":"Persistent postpartum urinary retention in contemporary obstetric practice.
