Radical prostatectomy presents a significant risk of postoperative sequelae, including erectile dysfunction. Postoperative erectile dysfunction adversely affects the patient\u2019s quality of life and can severely impact total treatment satisfaction. Nomograms have demonstrated efficacy in forecasting diverse outcomes in urology. We sought to create a nomogram to facilitate a more precise, evidence-based, and individualized prediction of erectile function outcomes following radical prostatectomy. Between January 2018 and January 2022, one hundred and eleven prostate cancer patients had robot-assisted radical prostatectomy, excluding those who had undergone prior transurethral prostatectomy, radiotherapy, or hormone therapy. Demographics, medical records, preoperative and postoperative erectile function statuses, and IIEF scores (\u226517 indicating retained erections, &lt;17 indicating full erectile dysfunction) were evaluated. Outcomes: Patients\u2019 ages ranged from 45 to 76 years, with an average of 61.18 \u00b1 6.72 years. Patients in the emergency department were considerably older (p = 0.004; p &lt; 0.01) and exhibited elevated Charlson Comorbidity Indices (3.63 \u00b1 0.85; p = 0.004; p &lt; 0.01). Preoperative IIEF scores in ED patients were lower (14.29 \u00b1 5.34), although obturator internus thickness (20.61 \u00b1 2.91) and intraprostatic urethra length (36.48 \u00b1 9.3) were considerably elevated. Altered surgical techniques were linked to maintained erections (p = 0.002; p &lt; 0.01), but traditional approaches were connected with erectile dysfunction (p = 0.007; p &lt; 0.01). Bilateral nerve-sparing procedures were more prevalent among patients preserving erectile function (p = 0.003; p &lt; 0.01). Conclusions: The nomogram, which includes age, Charlson Comorbidity Index, preoperative IIEF, obturator internus thickness, intraprostatic urethra length, surgical technique, and degree of nerve preservation, provides clinicians with a pragmatic instrument for forecasting postoperative erectile dysfunction in prostate cancer patients.<\/jats:p>","DOI":"10.3390\/jcm14144903","type":"journal-article","created":{"date-parts":[[2025,7,11]],"date-time":"2025-07-11T11:26:37Z","timestamp":1752233197000},"page":"4903","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Development of a Risk Model to Identify and Prevent Factors Influencing Erectile Dysfunction After Robotic Radical Prostatectomy"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4592-9369","authenticated-orcid":false,"given":"Hakan","family":"Karaca","sequence":"first","affiliation":[{"name":"Department of Urology, Ardahan State Hospital, 75000 Ardahan, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6219-9655","authenticated-orcid":false,"given":"Resul","family":"Sobay","sequence":"additional","affiliation":[{"name":"Department of Urology, Health Science University Umraniye Training and Research Hospital, 34764 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5155-4762","authenticated-orcid":false,"given":"Metin","family":"Mod","sequence":"additional","affiliation":[{"name":"Department of Urology, Basaksehir Cam Sakura City Hospital, 34480 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5158-5630","authenticated-orcid":false,"given":"Ahmet","family":"Tahra","sequence":"additional","affiliation":[{"name":"Department of Urology, Health Science University Umraniye Training and Research Hospital, 34764 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7632-1199","authenticated-orcid":false,"given":"Hasan Samet","family":"G\u00fcng\u00f6r","sequence":"additional","affiliation":[{"name":"Department of Urology, Health Science University Umraniye Training and Research Hospital, 34764 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2536-691X","authenticated-orcid":false,"given":"Abdurrahman","family":"\u0130nkaya","sequence":"additional","affiliation":[{"name":"Department of Urology, Health Science University Umraniye Training and Research Hospital, 34764 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ey\u00fcp Veli","family":"K\u00fc\u00e7\u00fck","sequence":"additional","affiliation":[{"name":"Department of Urology, Health Science University Umraniye Training and Research Hospital, 34764 Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.3322\/caac.21660","article-title":"Global Cancer Statistics 2020: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
