Nephroureterectomy with removal of a bladder cuff is the treatment of choice. The rates of TCC recurrence in the bladder after primary upper urinary tract surgery described in the literature range between 12.5 and 37.5%. In a retrospective analysis we examined the occurrence of TCC after nephroureterectomy for upper tract TCC in patients without a previous history of bladder TCC at the time of surgery. &lt;i&gt;Methods:&lt;\/i&gt; Between 1990 and 2002, 29 patients underwent primary nephroureterectomy for upper tract TCC. The mean age of the patients was 69.5 years. In 5 cases upper urinary tract tumors were multilocular, in the remaining cases unilocular in the renal pelvis (n = 12) or the ureter (n = 12). The follow-up was available for 29 patients with a mean follow-up of 3.37 (0.1\u201311.2) years. &lt;i&gt;Results:&lt;\/i&gt; 11\/29 (37.9%) patients had TCC recurrence with 9\/11 patients having bladder TCC diagnosed within 2.5 years (0.9\u20136.0) after nephroureterectomy. 13\/29 patients are alive without TCC recurrence, 3\/29 patients died due to systemic TCC progression and 5\/29 died of unrelated causes without evidence of TCC recurrence. &lt;i&gt;Conclusion:&lt;\/i&gt; Our data indicate a high incidence of bladder TCC after nephroureterectomy for primary upper tract TCC of up to 6 years after primary surgery. Because of the high incidence of bladder TCC within the first 3 years of surgery, careful follow-up is needed over at least this period.<\/jats:p>","DOI":"10.1159\/000080829","type":"journal-article","created":{"date-parts":[[2004,11,12]],"date-time":"2004-11-12T15:02:15Z","timestamp":1100271735000},"page":"209-211","source":"Crossref","is-referenced-by-count":11,"title":["Bladder Tumor Recurrence after Primary Surgery for Transitional Cell Carcinoma of the Upper Urinary Tract"],"prefix":"10.1159","volume":"73","author":[{"given":"S.","family":"Oehlschl\u00e4ger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Baldauf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Wiessner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Gellrich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O.W.","family":"Hakenberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.P.","family":"Wirth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2004,11,5]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1464-410X.1991.tb15064.x"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097%2F00005392-200112000-00003"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1464-410X.1989.tb05149.x"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2FS0094-0143%2803%2900062-4"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016%2FS0302-2838%2801%2900002-1"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2FS0090-4295%2899%2900563-4"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1159%2F000050969"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/80829","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/80829","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:39:10Z","timestamp":1745465950000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000080829"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004]]},"references-count":7,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2004,10,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000080829","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"type":"print","value":"0042-1138"},{"type":"electronic","value":"1423-0399"}],"subject":[],"published":{"date-parts":[[2004]]}}}
