Management of the distal ureter in patients undergoing this procedure remains controversial, however. We evaluated a new method involving cystoscopic sleeve resection of the distal ureter using a 2-\u03bcm continuous wave laser before LNU.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and Methods:<\/jats:title>\n                    <jats:p>LNU was performed in 38 patients at our hospital between January 2008 and January 2012. The distal end of the ureter was managed by using a 2-\u03bcm continuous wave laser to evaporate and excise the ureteral orifice and bladder cuff. A standard technique was applied to keep the ureter intact. The ureter was dissected to the entrance of the bladder, and the distal ureter was easily detached from the bladder.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The distal ureter was excised completely in all cases using this new technique. The average operative time was 2.4 hours, and the average blood loss was 69.4\u2009mL. At 1 year after surgery, the cause-specific survival rate of the patients was 100%, the bladder recurrence-free rate was 89%, and the extravesical recurrence-free rate was 100%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>For managing the distal ureter during LNU, the new technique described proved to be a simple, safe, and minimally invasive method.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/end.2014.0024","type":"journal-article","created":{"date-parts":[[2015,1,4]],"date-time":"2015-01-04T15:55:07Z","timestamp":1420386907000},"page":"430-434","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["A New 2-Micrometer Continuous Wave Laser Method for Management of the Distal Ureter in Retroperitoneal Laparoscopic Nephroureterectomy"],"prefix":"10.1177","volume":"29","author":[{"given":"Gang","family":"Guo","sequence":"first","affiliation":[{"name":"PLA General Hospital","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Yang","sequence":"additional","affiliation":[{"name":"PLA General Hospital","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Dong","sequence":"additional","affiliation":[{"name":"PLA General Hospital","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhou","family":"Zhenhong","sequence":"additional","affiliation":[{"name":"PLA General Hospital","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xu","family":"Zhang","sequence":"additional","affiliation":[{"name":"PLA General Hospital","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,4,1]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2004.04.011"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2005.10.022"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2004.08.006"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199105093241918"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2009.03.003"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1089\/end.2005.19.1151"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2009.02.154"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2007.01.007"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000145886.26719.73"},{"key":"e_1_3_2_11_2","first-page":"826725","article-title":"Laparoscopic nephroureterectomy: Oncologic outcomes and management of distal ureter; review of the literature","author":"Berger A","year":"2009","unstructured":"Berger A, , Fergany A.
