Methods: A total of 32 patients underwent EUS-RASP, and 30 underwent RASP from April 2018 to November 2021. All the perioperative data and 6-month follow-up data were collected prospectively. We retrospectively evaluated baseline characteristics and functional outcomes, including International Prostate Symptom Scores (IPSSs) and quality of life (QOL), maximum flow rate, and post-void residual volume, between the two groups. Sexual function was analyzed in the EUS-RASP group. Results: The patients undergoing EUS-RASP and RASP had comparable baseline characteristics and functional outcomes. The EUS-RASP group showed a shorter operative time (123.4 \u00b1 15.2 min vs. 133.7 \u00b1 21.4 min, p = 0.034), length of hospital stay (2.9 \u00b1 1.5 days vs. 4.6 \u00b1 1.5 days, p = 0.001), and catheterization time (2.4 \u00b1 1.7 days vs. 8.1 \u00b1 2.4 days, p &lt; 0.001). A total of 14\/32 (43.8%) patients reported normal preoperative ejaculatory function in the EUS-RASP group, and 11\/14 (78.6%) maintained antegrade ejaculation postoperatively. Conclusions: Extraperitoneal urethra-sparing RASP is an effective and feasible procedure that can improve voiding function and allow for the maintenance of ejaculatory function in patients with large prostates.<\/jats:p>","DOI":"10.3390\/jcm12144867","type":"journal-article","created":{"date-parts":[[2023,7,25]],"date-time":"2023-07-25T01:32:10Z","timestamp":1690248730000},"page":"4867","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Urethra-Sparing Robot-Assisted Simple Prostatectomy for Postoperative Antegrade Ejaculation"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3829-939X","authenticated-orcid":false,"given":"Sae Woong","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Urology, Yeouido St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 07345, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong Wan","family":"Sohn","sequence":"additional","affiliation":[{"name":"Department of Urology, Yeouido St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 07345, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U-Syn","family":"Ha","sequence":"additional","affiliation":[{"name":"Department of Urology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung-Hoo","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Urology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6775-1157","authenticated-orcid":false,"given":"Ji Youl","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Urology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyuk Jin","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Urology, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"513","DOI":"10.1016\/j.juro.2007.09.065","article-title":"Robotic simple prostatectomy","volume":"179","author":"Sotelo","year":"2008","journal-title":"J.
