Men with a history of neurogenic voiding dysfunction or major pelvic surgery were excluded. Multichannel videourodynamic studies were carried out, and the subsequent treatment modality offered was recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 67 men with urinary retention and a median age of 68 years underwent urodynamic evaluation. The median maximum flow rate was 3 mL\/s, and the median detrusor pressure at maximum flow was 54 cm H<jats:sub>2<\/jats:sub>O. Bladder outlet obstruction was diagnosed in 60%. Detrusor underactivity was present in 73% according to the bladder contractility index; however, just 29% were classified as having detrusor underactivity according to isometric detrusor pressure, an alternative measure of contractility. A total of 76% of patients had low detrusor reserve (&lt;20 cm H<jats:sub>2<\/jats:sub>O). Based on urodynamic findings, just 57% of patients were offered de\u2010obstructive surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In the present cohort, just 60% of men with urinary retention showed urodynamic evidence of bladder outlet obstruction. Depending on how contractility is measured (bladder contractility index <jats:italic>vs<\/jats:italic> isometric detrusor pressure), the rate of detrusor underactivity varies. The majority of men with retention had a low detrusor reserve. Given the wide spectrum of urodynamic findings in men with retention, surgical intervention might not be necessary for all. Furthermore, a careful consideration of urodynamics can assist in the selection of optimal treatment.<\/jats:p><\/jats:sec>","DOI":"10.1111\/iju.13395","type":"journal-article","created":{"date-parts":[[2017,7,7]],"date-time":"2017-07-07T23:56:36Z","timestamp":1499471796000},"page":"703-707","source":"Crossref","is-referenced-by-count":12,"title":["Urodynamics of men with urinary retention"],"prefix":"10.1111","volume":"24","author":[{"given":"David P","family":"Guo","sequence":"first","affiliation":[{"name":"Department of Urology Stanford University School of Medicine Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig V","family":"Comiter","sequence":"additional","affiliation":[{"name":"Department of Urology Stanford University School of Medicine Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S","family":"Elliott","sequence":"additional","affiliation":[{"name":"Department of Urology Stanford University School of Medicine Stanford California USA"},{"name":"Division of Urology Santa Clara Valley Medical Center San Jose California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2008.03.027"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2011.01.074"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eursup.2009.02.003"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.5489\/cuaj.10124"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2005.05891.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2012.11101.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.10066"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-4295(02)02243-4"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(01)66795-8"},{"issue":"6","key":"e_1_2_7_11_1","first-page":"S14","article-title":"Pressure flow urodynamic studies: the gold standard for diagnosing bladder outlet obstruction","volume":"7","author":"Nitti VW","year":"2005","journal-title":"Rev.
