Prevoiding drop in external urethral sphincter pressure was noted in all the volunteers, whereas it was not found in 6 of the 13 cases of BPH. Bladder neck opening pressure was higher in these 6 cases (p &lt; 0.05). After administration of phentolamine, prevoiding drop was noted in 5 of these 6 cases and bladder neck opening pressure decreased so much that there was no significant intergroup difference. The above results mean that the increase in \u03b1-adrenergic receptors makes the prostate, which has been already hypertrophied, less elastic, inhibiting external urinary sphincter function.<\/jats:p>","DOI":"10.1159\/000282248","type":"journal-article","created":{"date-parts":[[2010,2,3]],"date-time":"2010-02-03T05:55:56Z","timestamp":1265176556000},"page":"43-47","source":"Crossref","is-referenced-by-count":6,"title":["Change of External Urethral Sphincter Function in Prostatic Patients"],"prefix":"10.1159","author":[{"given":"K.","family":"Yasuda","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Nagashima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Murayama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Yamanishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Tojo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Shimazaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,2,3]]},"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000282248","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T16:58:27Z","timestamp":1777568307000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000282248"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,2,3]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000282248","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,2,3]]}}}
