Classic teaching, largely derived from the benefit seen in the muscle-invasive bladder cancer (MIBC) population, supports the inclusion of retroperitoneal lymph node dissection (LND), particularly for high-risk and high-grade disease. However, no level 1 evidence exists supporting the inclusion of an LND at the time of extirpative surgery for UTUC. Moreover, studies attempting to map lymph node dissection relative to primary UTUC tumor location are plagued by limitations. Herein, we summarize and review available data regarding proposed LND templates for the management of UTUC.<\/jats:p>","DOI":"10.3390\/cancers17233843","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T10:34:01Z","timestamp":1764758041000},"page":"3843","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Lymph Node Dissection for Upper Tract Urothelial Carcinoma: A Critical Appraisal of Lymph Node Mapping Studies"],"prefix":"10.3390","volume":"17","author":[{"given":"Jesse","family":"Persily","sequence":"first","affiliation":[{"name":"Department of Urology, NYU Langone Health, New York, NY 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon","family":"White","sequence":"additional","affiliation":[{"name":"Department of Urology, NYU Langone Health, New York, NY 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katie","family":"Murray","sequence":"additional","affiliation":[{"name":"Department of Urology, NYU Langone Health, New York, NY 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1016\/j.eururo.2023.03.013","article-title":"European Association of Urology Guidelines on Upper Urinary Tract Urothelial Carcinoma: 2023 Update","volume":"84","author":"Seisen","year":"2023","journal-title":"Eur.
