The operative time, stone-free rates (SFRs), serum creatinine (SCr), and complications were recorded. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; During the operation, there was no bleeding, ureteral perforation, avulsion, and rupture. Postoperative hematuria was observed in 2 patients. SCr increased significantly on the first day after the procedure compared with the preoperative SCr, but after 4 weeks, the renal function significantly improved (&lt;i&gt;p&lt;\/i&gt; &lt; 0.05). The SFR was 71.6% (63\/88) on the first day after the first surgical procedure; it then increased to 86.4% (76\/88) in the fourth week, and rose to 97.4% (76\/78) after the second operation. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; The results demonstrated that FURS in combination with holmium laser lithotripsy represented a favorable less-invasive alternative with high SFR and acceptable complication rates in the treatment of bilateral upper urinary tract calculi.<\/jats:p>","DOI":"10.1159\/000464141","type":"journal-article","created":{"date-parts":[[2017,3,27]],"date-time":"2017-03-27T21:23:25Z","timestamp":1490649805000},"page":"418-424","source":"Crossref","is-referenced-by-count":18,"title":["Safety and Efficacy of Flexible Ureteroscopy in Combination with Holmium Laser Lithotripsy for the Treatment of Bilateral Upper Urinary Tract Calculi"],"prefix":"10.1159","volume":"98","author":[{"given":"Bing","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Ning","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zheng","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengfan","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianghua","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongliang","family":"Pan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kejia","family":"Ding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2017,3,28]]},"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/464141","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/464141","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/464141","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:32:27Z","timestamp":1745429547000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000464141"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2017,5,30]]},"published-print":{"date-parts":[[2017,5,30]]}},"URL":"https:\/\/doi.org\/10.1159\/000464141","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
