Consensus was noted with regard to 6 of 19 questions. Experts strongly agreed with utility of quantifying bladder contractility and bladder outflow obstruction with near unanimity regarding the latter. There was consensus that BCI and BOOI were accurate, that BCI was clinically useful, and for defining severe bladder outflow obstruction as BOOI\u2009&gt;\u200980. Systematic search yielded 69 publications (BCI 45; BOOI 50).

Few studies have examined the discriminant power of existing cutoffs or explored new ones.

urology.<\/jats:p><\/jats:sec>","DOI":"10.1002\/nau.25073","type":"journal-article","created":{"date-parts":[[2022,10,23]],"date-time":"2022-10-23T19:05:10Z","timestamp":1666551910000},"page":"229-238","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The
