In cases requiring urgent decompression or delayed definitive treatment, JJ stenting is frequently employed. However, prolonged indwelling time may increase the risk of bacterial colonization and subsequent infectious complications, though evidence remains limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective, single-center study including 350 adult patients who underwent URS at the Department of Urology, Lausanne University Hospital (CHUV) between January and December 2023.
