Our institute has been implementing CVP for BPH since 2018, treating a total of 93 patients, including 28 with a risk of hemorrhage. This study examines the safety and efficacy of CVP treatment for BPH patients with a hemorrhagic risk.<\/jats:p><jats:p><jats:bold>Patient and Methods:<\/jats:bold> A total of 93 BPH patients with lower urinary tract symptoms (LUTS) underwent CVP between February 2018 and September 2022. All patients were on medications for BPH and were refractory to these medications. The median (mean\u2009\u00b1\u2009SD) age was 72 (72.9\u00b16.27), and the prostate volume was 64 (68.9\u00b132.5). IPSS, QOL index, and OABSS scores for patients not requiring catheterization were 22 (22.1\u00b16.38), 5 (5.24\u00b10.74), and 6 (7\u00b13.29), respectively. The CVP treatment was performed using a 980\u2009nm diode laser. Of the 93 patients, 28 (30.1%) had a hemorrhage risk. This group included 13 (14.0%) who were continuously receiving anticoagulant and\/or antiplatelet agents, 13 (14.0%) who temporarily stopped these medications, and 2 (2.1%) who had a hemorrhage risk due to low platelet counts (&lt; 5.0\u2009\u00d7\u200910<jats:sup>4<\/jats:sup>\/<jats:italic>\u03bc<\/jats:italic>L).<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Postoperatively, 15 (16.1%) patients, including 11 who were catheterized preoperatively, needed temporary catheterization after CVP treatment. Of these, 14 had their catheters successfully removed. The IPSS score significantly decreased from 22 (22.1\u00b16.38) to 8 (9.02\u00b16.07) (<jats:italic>p<\/jats:italic> &lt; 0.0001). In patients with hemorrhagic risk on anticoagulant and\/or antiplatelet agents, the change in hemoglobin level before and after surgery was 0.6\u2009g\/dL, a difference that was not significant. Two of the 15 patients with hemorrhagic risk experienced hemorrhage 23 and 26\u2009days postoperatively and underwent transurethral coagulation. Other perioperative complications classified as Clavien\u2013Dindo Grade 2 or higher occurred in 4 (4.3%) patients.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> CVP treatment appears to be acceptable for BPH patients with hemorrhagic risk. In this study, late\u2010onset hemorrhage occurred approximately 1\u2009month postoperatively. Close postoperative follow\u2010up is required.<\/jats:p>","DOI":"10.1155\/aiu\/6108816","type":"journal-article","created":{"date-parts":[[2024,12,19]],"date-time":"2024-12-19T16:06:23Z","timestamp":1734624383000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Initial Experience of Contact Laser Vaporization of the Prostate (CVP) for Benign Prostate Hyperplasia Patients With Hemorrhagic Risk"],"prefix":"10.1155","volume":"2024","author":[{"given":"Yushi","family":"Araki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7049-3379","authenticated-orcid":false,"given":"Takashi","family":"Kawahara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teppei","family":"Takeshima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhide","family":"Makiyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroji","family":"Uemura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,19]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.5213\/inj.2013.17.2.59"},{"key":"e_1_2_13_2_2","first-page":"132","article-title":"Clinical Outcomes of Transurethral Enucleation With Bipolar for Benign Prostatic Hypertrophy","volume":"40","author":"Kawamura Y.","year":"2015","journal-title":"Tokai Journal of Experimental & Clinical Medicine"},{"key":"e_1_2_13_3_2","doi-asserted-by":"crossref","first-page":"452","DOI":"10.1016\/j.urology.2014.04.067","article-title":"Safety and Efficacy of Quartz Head Contact Laser Ablation for Large Prostates Using 980-nm Laser: A Comparative Prospective Study against that for Small- and Medium-Sized Prostates","volume":"85","author":"Shaker H.
