Our patient cohort was divided into two groups: an emergency URS group (Group A), which consisted of patients who underwent URS within the first 24\u2009h of admission, and an elective or planned URS group (Group B). The URS success rate was defined as being the incidence of successful stone fragmentation and whether there was resolution of renal obstruction. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> A total of 2957 patients\u2019 medical records were available for analysis. Of these, 704 (21%) comprised of emergency cases and the remaining 2253 (79%) were elective cases. Patients in Group A were younger, had a smaller BMIs, and had smaller stone sizes ( p\u2009&lt;\u20090.001). The URS success rate was found to be 97% in Group A and 96% in Group B ( p\u2009=\u20090.35). Intraoperative or postoperative complication rates were not found to vary significantly between the groups (8% vs 7%, respectively, p\u2009=\u20090.50). The incidence of ureteral stenting was nearly twice as high if URS was performed during night hours (85% vs 45%, p\u2009&lt;\u20090.001). However, ureteral stenting was more prevalent in Group B compared to Group A patients (57% vs 25%, p\u2009&lt;\u20090.001), possibly as a result of the number of pre-stented patients (73%). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> Emergency URS is an effective and safe option for patients with renal colic. Younger patients without pre-existing obesity and with stone sizes up to 8\u2009mm located in the distal ureter might be a better match for emergency URS. <\/jats:p><\/jats:sec>","DOI":"10.1177\/0391560320987163","type":"journal-article","created":{"date-parts":[[2021,1,14]],"date-time":"2021-01-14T01:01:20Z","timestamp":1610586080000},"page":"79-84","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Emergency versus elective ureteroscopy for the management of ureteral stones"],"prefix":"10.1177","volume":"89","author":[{"given":"Nariman K","family":"Gadzhiev","sequence":"first","affiliation":[{"name":"Department of Urology, Pavlov First Saint Petersburg State Medical University, Saint-Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gagik N","family":"Akopyan","sequence":"additional","affiliation":[{"name":"Institute for Urology and Reproductive Health, Sechenov University, Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farzona I","family":"Tursunova","sequence":"additional","affiliation":[{"name":"Institute for Urology and Reproductive Health, Sechenov University, Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew S","family":"Afyouni","sequence":"additional","affiliation":[{"name":"Department of Urology, University of California, Irvine, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8861-8187","authenticated-orcid":false,"given":"Dmitry O","family":"Korolev","sequence":"additional","affiliation":[{"name":"Institute for Urology and Reproductive Health, Sechenov University, Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitry G","family":"Tsarichenko","sequence":"additional","affiliation":[{"name":"Institute for Urology and Reproductive Health, Sechenov University, Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonid M","family":"Rapoport","sequence":"additional","affiliation":[{"name":"Institute for Urology and Reproductive Health, Sechenov University, Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhamshid","family":"Okhunov","sequence":"additional","affiliation":[{"name":"Department of Urology, University of California, Irvine, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Somani","family":"Bhaskar","sequence":"additional","affiliation":[{"name":"Department of Urology, University Hospital Southhampton NHS Foundation Trust, Southampton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vigen A","family":"Malkhasyan","sequence":"additional","affiliation":[{"name":"Department of Urology, A.I.
