Methods: A retrospective analysis of 35 patients received preoperative ureteral stenting prior to NSS for complex tumours at the University Hospital of W\u00fcrzburg between 2002 and 2021. A control group of 115 patients was established through 1:3 propensity score matching based on age, gender, T-stage, and RENAL score. Clinical parameters, surgical outcomes, and complications were assessed, and statistical comparisons were performed using the unpaired Student\u2019s t test and chi-square test. Results: While both groups showed comparable tumour complexity (RENAL: 7 vs. 7, p = 0.58; PADUA: 9 vs. 8, p = 0.62), there were no significant differences in median hospital stay (12 vs. 11; p = 0.068), surgical time (183 vs. 190 min; p = 0.37), post-operative haemoglobin levels (11 g\/dL vs. 11.1 day\/dL; p = 0.9), and renal function (GFR 65 mL\/min\/m2 in both groups). Moreover complication severity during NSS, defined by Clavien-Dindo classification, was similar (none vs. grade I; p = 0.29). No significant difference in the rate of urinoma was observed (11% vs. 4%, p = 0.93). Conclusions: This study found no significant benefits of preoperative ipsilateral ureteral stenting on post-operative outcomes, particularly concerning the development of urinoma. Given these findings, preventive ureteral stenting is not recommended prior to partial kidney resection for complex renal tumours. <\/jats:p>","DOI":"10.1159\/000543073","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T17:01:04Z","timestamp":1734022864000},"page":"278-284","source":"Crossref","is-referenced-by-count":0,"title":["An Analysis of Renal and Surgical Outcomes of Patients with and without Preoperative Ureteral Stenting before Nephron-Sparing Surgery for Renal Malignancies of Higher Complexity by Using a Propensity Score-Based Approach"],"prefix":"10.1159","volume":"109","author":[{"given":"Marcel","family":"Schwinger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johanna","family":"Wege","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Hahn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hubert","family":"K\u00fcbler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent","family":"Scheper","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charis","family":"Kalogirou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2024,12,11]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007\/s00120-011-2677-5"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.4321\/s0004-06142007000900004"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2012.05.009"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2012.02.039"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/PPO.0b013e31818675ae"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1089\/end.2016.0082"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1089\/end.2016.0351"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.23736\/S0393-2249.19.03391-5"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2020.08.046"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2004.04925.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2009.08490.x"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.4103\/iju.iju_393_21"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2014.03.010"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2013.09.006"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000147177.20458.73"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2011.03.127"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1148\/rg.265065701"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016\/j.clgc.2017.01.023"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2008.08.018"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000130332.35800.08"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1590\/S1677-5538.IBJU.2014.06.07"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1097\/BSD.0000000000000932"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.4103\/ua.ua_37_23"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-5347(01)66845-9"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000543073","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000543073","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,5]],"date-time":"2025-06-05T16:02:15Z","timestamp":1749139335000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000543073"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12,11]]},"references-count":24,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2025,6,5]]},"published-print":{"date-parts":[[2025,6,3]]}},"URL":"https:\/\/doi.org\/10.1159\/000543073","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"type":"print","value":"0042-1138"},{"type":"electronic","value":"1423-0399"}],"subject":[],"published":{"date-parts":[[2024,12,11]]}}}
