The\u00a0stone-free rate was evaluated. The effectiveness, safety, surgical\u00a0technique, incidence of complications, and relevant treatments\u00a0were analyzed.Results: All patients underwent only one lithotripsy procedure.\u00a0The success rate of flexible ureteroscopy was 97.2% (105\/108).\u00a0Among the 105 cases, the total lithotripsy success rate was 97.1%\u00a0(101\/105). The total stone-free rate after 8 weeks post-operation\u00a0was 94.3% (99\/105), the stone-free rate of the lower calyx was\u00a085.7% (30\/35); it was 98.6% (69\/70) in the middle\u2012upper calyceal\u00a0and renal pelvis. The incidence of complications was 12.9%\u00a0(14\/108). None of the patients had serious adverse outcomes.Conclusion: Flexible ureteroscopy represents an optimal treatment option for selected renal calculi with burden of &lt;2 cm. The effectiveness and safety of flexible ureteroscopy can be further improved through reasonable preoperative evaluation and advances in surgical techniques, as well as a better understanding of the inducement and treatment of complications.<\/jats:p>","DOI":"10.5489\/cuaj.2649","type":"journal-article","created":{"date-parts":[[2015,5,19]],"date-time":"2015-05-19T19:15:34Z","timestamp":1432062934000},"page":"273","source":"Crossref","is-referenced-by-count":5,"title":["Improved effectiveness and safety of flexible ureteroscopy for renal calculi (&lt;2 cm): A retrospective study"],"prefix":"10.5489","volume":"9","author":[{"given":"Shuqiu","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hua","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaowen","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guozhu","family":"Sha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weidong","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3456","published-online":{"date-parts":[[2015,5,13]]},"container-title":["Canadian Urological Association Journal"],"original-title":[],"link":[{"URL":"http:\/\/www.cuaj.ca\/index.php\/journal\/article\/viewFile\/2649\/2145","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.cuaj.ca\/index.php\/journal\/article\/viewFile\/2649\/2145","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T15:47:42Z","timestamp":1501602462000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.cuaj.ca\/index.php\/journal\/article\/view\/2649"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,5,13]]},"references-count":0,"journal-issue":{"issue":"5-6","published-online":{"date-parts":[[2015,5,13]]}},"URL":"https:\/\/doi.org\/10.5489\/cuaj.2649","relation":{},"ISSN":["1920-1214","1911-6470"],"issn-type":[{"value":"1920-1214","type":"electronic"},{"value":"1911-6470","type":"print"}],"subject":[],"published":{"date-parts":[[2015,5,13]]}}}
