This study examined epidemiological trends, nephron-sparing surgery adoption, and the perioperative impact of lymphadenectomy (LND) and neoadjuvant chemotherapy (NAC). Methods: The German Nationwide Inpatient Data (GRAND) registry (2005\u20132023) identified UTUC patients undergoing radical nephroureterectomy (RNU), endoscopic laser destruction, or segmental ureteral resection (SUR) using OPS codes. Demographics, comorbidities, complications, and in-hospital mortality were extracted from ICD-10-GM data. Multivariable regression adjusted for baseline comorbidities assessed associations between treatment type, LND, NAC, and perioperative outcomes. Results: Among 53,427 UTUC patients, 77.3% underwent RNU, 13.8% endoscopic laser destruction, and 8.9% SUR. Endoscopic laser use rose from &lt;10% (2005) to about 20% (2023). LND was performed in 13% of RNU cases, increasing from 1.1% to 19%. LND was associated with higher risks of transfusion (OR 1.47, 95% CI 1.37\u20131.57), acute kidney injury (OR 1.19, 95% CI 1.07\u20131.32), and ICU admission (OR 1.21, 95% CI 1.13\u20131.30), without affecting in-hospital mortality. NAC was given to 1.7% of patients, with a five-fold increase over time, and was associated with more transfusions (OR 1.28, 95% CI 1.07\u20131.52) and urinomas (OR 2.31, 95% CI 1.31\u20133.78), but not mortality. Conclusions: UTUC management is evolving, with growing use of endoscopic laser therapy and guideline-aligned lymphadenectomy during nephroureterectomy. Neoadjuvant chemotherapy remains underused despite acceptable perioperative safety, highlighting the need for increased awareness to optimize multimodal treatment.<\/jats:p>","DOI":"10.3390\/jcm15072536","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T13:48:41Z","timestamp":1774532921000},"page":"2536","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Trends in Treatment and Perioperative Outcomes of Upper Tract Urothelial Carcinoma: The Evolving Role of Lymphadenectomy and Neoadjuvant Chemotherapy"],"prefix":"10.3390","volume":"15","author":[{"given":"Robert","family":"Bischoff","sequence":"first","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolaos","family":"Pyrgidis","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benedikt","family":"Ebner","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5468-9398","authenticated-orcid":false,"given":"Yannic","family":"Volz","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julian","family":"Hermans","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie","family":"Semmler","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1565-1258","authenticated-orcid":false,"given":"Patrick","family":"Keller","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0340-0304","authenticated-orcid":false,"given":"Gerald B.","family":"Schulz","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julian","family":"Marcon","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Weinhold","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3291-9460","authenticated-orcid":false,"given":"Christian G.","family":"Stief","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9971-4411","authenticated-orcid":false,"given":"Lennert","family":"Eismann","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Munich, Ludwig Maximilian University of Munich, Marchioninistr. 15, 81377 Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"53","DOI":"10.1097\/MOU.0000000000001242","article-title":"Upper tract urothelial carcinoma: Epidemiology, presentation, and high-risk endemic populations","volume":"35","author":"Clark","year":"2025","journal-title":"Curr.
