The pathogenesis of ureteral stricture formation is not yet fully understood. It is likely that the patient and stone characteristics, as well as intervention factors, play a role in this process. In this systematic review, we aimed to determine the potential factors responsible for ureteral stricture formation in patients having impacted ureteral stones. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) criteria, we conducted systematic online research through PubMed and Web of Science without a time restriction, applying the keywords \u201cureteral stone\u201d, \u201cureteral calculus\u201d, \u201cimpacted stone\u201d, \u201cureteral stenosis\u201d, \u201cureteroscopic lithotripsy\u201d, \u201cimpacted calculus\u201d, and \u201cureteral strictures\u201d singly or in combination. Results: After eliminating non-eligible studies, we identified five articles on ureteral stricture formation following treatment of impacted ureteral stones. Ureteral perforation and\/or mucosal damage appeared as key predictors of ureteral stricture following retrograde ureteroscopy (URS) for impacted ureteral stones. Besides ureteral perforation stone size, embedded stone fragments into the ureter during lithotripsy, failed URS, degree of hydronephrosis, nephrostomy tube or double-J stent (DJS)\/ureter catheter insertion were also suggested factors leading to ureteral strictures. Conclusion: Ureteral perforation during surgery might be considered the main risk factor for ureteral stricture formation following retrograde ureteroscopic stone removal for impacted ureteral stones.<\/jats:p>","DOI":"10.3390\/jcm12103603","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T02:02:27Z","timestamp":1684807347000},"page":"3603","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Predictors of Ureteral Strictures after Retrograde Ureteroscopic Treatment of Impacted Ureteral Stones: A Systematic Literature Review"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1657-4044","authenticated-orcid":false,"given":"Senol","family":"Tonyali","sequence":"first","affiliation":[{"name":"Department of Urology, Istanbul Faculty of Medicine, Istanbul University, 34452 Istanbul, Turkey"},{"name":"Department of Urology, Faculty of Medicine, Medical Center, University of Freiburg, 79106 Freiburg, Germany"},{"name":"European Association of Urology, Young Academic Urologist Endourology and Urolithiasis Working Party, NL-6803 Arnhem, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3774-9982","authenticated-orcid":false,"given":"Mehmet","family":"Yilmaz","sequence":"additional","affiliation":[{"name":"Department of Urology, Faculty of Medicine, Medical Center, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4619-9783","authenticated-orcid":false,"given":"Lazaros","family":"Tzelves","sequence":"additional","affiliation":[{"name":"European Association of Urology, Young Academic Urologist Endourology and Urolithiasis Working Party, NL-6803 Arnhem, The Netherlands"},{"name":"Department of Urology\/Uro-Oncology, University College of London Hospitals (UCLH), London NW1 2BU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4488-0022","authenticated-orcid":false,"given":"Esteban","family":"Emiliani","sequence":"additional","affiliation":[{"name":"European Association of Urology, Young Academic Urologist Endourology and Urolithiasis Working Party, NL-6803 Arnhem, The Netherlands"},{"name":"Department of Urology, Fundacio Puigvert, Autonomous University of Barcelona, 08193 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4983-5055","authenticated-orcid":false,"given":"Vincent De","family":"De Coninck","sequence":"additional","affiliation":[{"name":"European Association of Urology, Young Academic Urologist Endourology and Urolithiasis Working Party, NL-6803 Arnhem, The Netherlands"},{"name":"Department of Urology, AZ Klina, 2930 Brasschaat, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Etienne Xavier","family":"Keller","sequence":"additional","affiliation":[{"name":"European Association of Urology, Young Academic Urologist Endourology and Urolithiasis Working Party, NL-6803 Arnhem, The Netherlands"},{"name":"Department of Urology, University Hospital Zurich, University of Zurich, 8006 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arkadiusz","family":"Miernik","sequence":"additional","affiliation":[{"name":"Department of Urology, Faculty of Medicine, Medical Center, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"841","DOI":"10.1007\/s11255-020-02375-4","article-title":"Post ureteroscopic stone surgery ureteral strictures management: A retrospective study","volume":"52","author":"Xiong","year":"2020","journal-title":"Int.
