From the initially retrieved 609 reports, we excluded the ineligible studies at 2 stages. We only included studies that contained fURS patients with and without POS in the same report. Data of patients who underwent semirigid ureteroscope only were excluded from the analysis. The Newcastle-Ottawa Scale (NOS) system was applied for risk of bias assessment. <b><i>Results:<\/i><\/b> A total of 20 studies including 5,852 patients were involved. 48.5% of the patients had preoperative stent. Stone-free rate was significantly higher with prestenting; odds ratio (OR) was 1.98 (95% CI: 1.51\u20132.58) (<i>Z<\/i> = 5.02; <i>p<\/i> = 0.00001). It also displayed tendency toward lower complications; OR was 0.74 (95% CI: 0.52\u20131.05) (<i>Z<\/i> = 1.67; <i>p<\/i> = 0.09). POS significantly increased the use of ureteral access sheath; OR was 1.49 (95% CI: 1.05\u20132.13) (<i>Z<\/i> = 2.22; <i>p<\/i> = 0.03). Risk of bias assessment showed 13 and 7 studies with low and moderate risk, respectively. <b><i>Conclusions:<\/i><\/b> POS clearly improves the stone-free rates after fURS. It might reduce the complications, especially ureteral injury. These findings might help solve the current debate and can be useful for urologists during patient counselling for a proper decision-making. <\/jats:p>","DOI":"10.1159\/000518160","type":"journal-article","created":{"date-parts":[[2021,8,25]],"date-time":"2021-08-25T21:00:43Z","timestamp":1629925243000},"page":"679-687","source":"Crossref","is-referenced-by-count":22,"title":["Impact of Preoperative Stenting on the Outcome of Flexible Ureterorenoscopy for Upper Urinary Tract Urolithiasis: A Systematic Review and Meta-Analysis"],"prefix":"10.1159","volume":"106","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1631-2733","authenticated-orcid":false,"given":"Omar","family":"Fahmy","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hadi","family":"SHSM","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CKS","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohd Ghani","family":"Khairul-Asri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2015.07.040"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1089\/end.2015.0260"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s11934-015-0529-3"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000048980.33855.90"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1186\/s12894-020-00715-1"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159\/000504682"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.29271\/jcpsp.2019.06.558"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159\/000494362"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.7717\/peerj.2728"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1186\/2046-4053-4-1"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-018-2519-9"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-017-2075-8"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpurol.2017.01.015"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1089\/end.2016.0201"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1089\/end.2015.0109"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1007\/s11255-016-1311-2"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1089\/end.2016.0045"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1186\/s12894-015-0016-7"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1111\/bju.13250"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-011-0789-6"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2012.08.197"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-2042.2012.03046.x"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2012.06.064"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2009.08.043"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1089\/end.2007.9888"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-5347(17)43119-3"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1089\/end.2010.0188"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-018-2204-z"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1089\/end.2014.0215"},{"key":"ref30","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0193600"},{"key":"ref31","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2011.10.033"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518160","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518160","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:12:03Z","timestamp":1745421123000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000518160"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,8,25]]},"references-count":31,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2022,7,6]]},"published-print":{"date-parts":[[2022,7,6]]}},"URL":"https:\/\/doi.org\/10.1159\/000518160","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,8,25]]}}}
