In this paper, we present a different use of a basket catheter for the treatment of proximal ureteral stones. Methods: Between September 2016 and January 2019, 101 patients over 18 years of age detected to have a maximum 15-mm proximal ureteral stone were retrospectively evaluated, and 93 patients fulfilling the criteria were included in the study. Semi-rigid URS and a modified basket catheter were used together in 44 patients while no auxiliary equipment was utilized for the remaining 49 patients. In the study group, a 3F zero-tip basket catheter was disintegrated and positioned in a way to capture and retrieve the stone from the semi-rigid ureterorenoscope. Results: No difference was found between the two groups in terms of age, body mass index, gender, and stone characteristics. The duration of operation was shorter in the basket catheter group (p &amp;lt; 0.001). The rates of stone migration, requirement to switch to flexible ureterorenoscopy (FURS), and double J-stent (JJ-stent) placement were significantly higher in the control group (p &amp;lt; 0.005). There were no significant differences between the two groups concerning operation success and complications (p = 0.068 and p = 0.772, respectively). Conclusions: The modified basket catheter technique with semi-rigid URS was successful in preventing the migration of proximal ureteral stones. This method can be considered as an alternative in cases where FURS is not available. </dc:description><dc:date>2021</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/17952</dc:identifier><dc:identifier>https://doi.org/10.18621/eurj.643381</dc:identifier><dc:language>en</dc:language><dc:relation>The European Research Journal</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/17952</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
