Materials and methods: Patients treated at our clinic for 11-20 mm single stones in the proximal ureter who underwent f-URS, sr-URS or SWL as initial lithotripsy methods were compared in terms of their clinical characteristics and treatment outcomes. Results: A comparison among 201 patients who had undergone f-URS, 119 patients who had undergone sr-URS, and 162 patients who had undergone SWL showed no significant baseline differences in patients\u2019 demographic and stone characteristics. Stone-free rates on the 15th day and 3rd month were higher with f-URS (89.6% and 97%, respectively) than with sr-URS (67.2% and 94.1%, respectively) and SWL (41.4% and 79.0%, respectively; all p &lt; 0.001). Retreatment rates were significantly higher with SWL than with the other two modalities (p &lt; 0.001); auxiliary procedure rates were significantly lower with f-URS than with the other two modalities (p &lt; 0.001). Treatment-related complication rate at the end of the 3rd month was lower with f-URS than with SWL (p = 0.022). Furthermore, f-URS was more effective than sr-URS for treating impacted stones. Conclusions: We found that f-URS was highly successful as an initial lithotripsy procedure for medium-sized proximal ureteral stones, and it helped achieve early stone-free outcomes with a lower need for retreatment and auxiliary procedures, lower complication rates, and higher effectiveness on the impacted stones compared with sr-URS and SWL.<\/jats:p>","DOI":"10.4081\/aiua.2020.1.39","type":"journal-article","created":{"date-parts":[[2020,4,6]],"date-time":"2020-04-06T19:45:12Z","timestamp":1586202312000},"page":"39-44","source":"Crossref","is-referenced-by-count":12,"title":["Comparison of semirigid ureteroscopy, flexible ureteroscopy, and shock wave lithotripsy for initial treatment of 11-20 mm proximal ureteral stones"],"prefix":"10.4081","volume":"92","author":[{"given":"Ibrahim","family":"Kartal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Burhan","family":"Baylan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehmet \u00c7a\u011flar","family":"\u00c7ak\u0131c\u0131","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sercan","family":"Sar\u0131","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Volkan","family":"Selmi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harun","family":"Ozdemir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatih","family":"Yal\u00e7\u0131nkaya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2549","published-online":{"date-parts":[[2020,4,6]]},"container-title":["Archivio Italiano di Urologia e Andrologia"],"original-title":[],"link":[{"URL":"https:\/\/pagepressjournals.org\/index.php\/aiua\/article\/download\/aiua.2020.1.39\/8663","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/pagepressjournals.org\/index.php\/aiua\/article\/download\/aiua.2020.1.39\/8663","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,10,28]],"date-time":"2020-10-28T21:39:48Z","timestamp":1603921188000},"score":1,"resource":{"primary":{"URL":"https:\/\/pagepressjournals.org\/index.php\/aiua\/article\/view\/aiua.2020.1.39"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,4,6]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2020,3,31]]}},"URL":"https:\/\/doi.org\/10.4081\/aiua.2020.1.39","relation":{},"ISSN":["2282-4197","1124-3562"],"issn-type":[{"value":"2282-4197","type":"electronic"},{"value":"1124-3562","type":"print"}],"subject":[],"published":{"date-parts":[[2020,4,6]]}}}
