The mean age was 66.8 years (SD \u00b111.313); the mean body mass index was 24.76 (SD \u00b15.091). In all cases, the surgical technique was defined by tumor characteristics and the surgeon's preferences. <b><i>Results:<\/i><\/b> Surgery was technically successful in all 11 patients. A hand-assisted approach was performed in 3 patients, while pure laparoscopy was used in 8. The mean surgical time was 108.3 min (SD \u00b128.284); the mean estimated blood loss was 108.33 ml (SD \u00b1106.066); the average hospital stay was 2.8 days (SD \u00b10.707). There was 1 intraoperative complication (splenic laceration) that was managed laparoscopically. Pathologic examination confirmed RCC in all cases. There were no positive surgical margins. With a mean follow-up of 29 months (27-39), 2 patients had a recurrence. <b><i>Conclusion:<\/i><\/b> This report provides further evidence of the technical feasibility, safety and oncologic adequacy of the laparoscopic approach in RCC with level 1 renal vein involvement. A longer follow-up and multi-institutional studies are needed to adequately evaluate its potential oncologic benefit.<\/jats:p>","DOI":"10.1159\/000363580","type":"journal-article","created":{"date-parts":[[2014,9,9]],"date-time":"2014-09-09T07:51:33Z","timestamp":1410249093000},"page":"88-92","source":"Crossref","is-referenced-by-count":4,"title":["Laparoscopic Management of Renal Tumors with Macroscopic Level 1 Renal Vein Involvement"],"prefix":"10.1159","volume":"94","author":[{"given":"Octavio","family":"Castillo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrique","family":"Alem\u00e1n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2014,9,5]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3322\/CA.2007.0010"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-4295(97)00506-2"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-4295(00)00534-3"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2004.04897.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-200207000-00039"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2010.07.006"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2006.03.031"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2009.06.009"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-199604000-00004"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2004.04925.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-200004000-00043"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2007.01.008"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1097\/01.sla.0000133083.54934.ae"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-200212000-00090"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-200209000-00045"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000045706.35470.1e"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(01)06103-7"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa003013"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/363580","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/363580","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:50:07Z","timestamp":1745430607000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000363580"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,9,5]]},"references-count":18,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2015,1,1]]},"published-print":{"date-parts":[[2015,1,29]]}},"URL":"https:\/\/doi.org\/10.1159\/000363580","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,9,5]]}}}
