Inclusion criteria were an estimated prostate volume of 30\u201380 cc, International Prostate Symptom Score (IPSS) \u226512, and maximum urinary flow rate <16 mL\/sec. ML protrusion was assessed using ultrasound (with bladder volume \u2265250 cc) and flexible cystoscopy; the average of both measurements was used to classify ML protrusion into <5 mm, 5\u201310 mm, and >10 mm. Primary outcomes included postoperative complications such as surgical retreatment, acute urinary retention (AUR), and urinary tract infections (UTIs).<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n With a median follow-up of 29.1 months (range: 24\u201336), improvements in lower urinary tract symptoms (LUTS) were similar across all groups, with consistent symptom reduction (\u0394 = \u221213) in both obstructive and irritative IPSS components. Rates of AUR and UTIs showed no significant variation across groups: AUR (no ML 9.5%; <5 mm 8.7%; 5\u201310 mm 12%; >10 mm 17%;\n p<\/jats:italic>\n = 0.7) and UTI (no ML 8.4%; <5 mm 4.3%; 5\u201310 mm 9.3%; >10 mm 8.3%;\n p<\/jats:italic>\n = 0.8). Despite comparable preoperative characteristics, surgical retreatment rates varied significantly with ML protrusion: no ML (3.2%), <5 mm (4.3%), 5\u201310 mm (14%), and >10 mm (21%) (\n p<\/jats:italic>\n = 0.007), highlighting increased retreatment risk associated with greater ML protrusion.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n WVTT effectively relieves LUTS across all ML configurations. However, patients with greater ML protrusion may face a higher risk of retreatment, likely because of increased bladder neck and urethral involvement. These findings suggest that detailed ML assessment can aid in patient counseling and stratification.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/08927790251412401","type":"journal-article","created":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T06:01:15Z","timestamp":1769061675000},"page":"205-211","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of Median Lobe Protrusion on Outcomes of Water Vapor Thermal Therapy for Benign Prostatic Hyperplasia: A Prospective Analysis"],"prefix":"10.1177","volume":"40","author":[{"given":"Juan","family":"Fulla","sequence":"first","affiliation":[{"name":"Department of Urology, Hospital Cl\u00ednico San Borja Arriar\u00e1n, Santiago, Chile."},{"name":"Department of Urology, University of Chile, Santiago, Chile."},{"name":"Cl\u00ednica MEDS, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Sebastian","family":"Arroyave","sequence":"additional","affiliation":[{"name":"Department of Urology, Icahn School of Medicine at Mount Sinai, New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisca","family":"Larenas","sequence":"additional","affiliation":[{"name":"Department of Urology, Hospital Cl\u00ednico San Borja Arriar\u00e1n, Santiago, Chile."},{"name":"Department of Urology, University of Chile, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven A.","family":"Kaplan","sequence":"additional","affiliation":[{"name":"Department of Urology, Icahn School of Medicine at Mount Sinai, New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Palese","sequence":"additional","affiliation":[{"name":"Department of Urology, Icahn School of Medicine at Mount Sinai, New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Sanchez","sequence":"additional","affiliation":[{"name":"Cl\u00ednica MEDS, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,1,21]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-020-03457-9"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrdp.2016.31"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-017-06628-8"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2014.12.038"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-024-05017-x"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2005.12.042"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.euros.2022.03.006"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/JU.0000000000001778"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.5173\/ceju.2011.02.art5"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1159\/000049784"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.2147\/RRU.S143679"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.2147\/RRU.S119596"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41391-017-0022-9"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.purol.2020.05.004"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/pros.24201"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2022.02.001"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2017.10.023"}],"container-title":["Journal of Endourology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/08927790251412401","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/08927790251412401","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/08927790251412401","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T20:17:48Z","timestamp":1777407468000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/08927790251412401"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,21]]},"references-count":17,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026,2,1]]}},"alternative-id":["10.1177\/08927790251412401"],"URL":"https:\/\/doi.org\/10.1177\/08927790251412401","relation":{},"ISSN":["0892-7790","1557-900X"],"issn-type":[{"value":"0892-7790","type":"print"},{"value":"1557-900X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1,21]]}}}
