Urothelial carcinoma (UC) is the most common urinary neoplasm in dogs. Earlier detection of UC by noninvasive means could lead to improved outcomes. Urinary 15-F2-isoprostanes potentially could provide this means, but have not been evaluated in dogs with UC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>The objective of this study was to measure urinary 15-F2-isoprostanes in dogs with UC and dogs with other LUTD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Animals<\/jats:title>\n                    <jats:p>One hundred seventeen dogs: 46 dogs with UC, 30 dogs with LUTD, and 25 control dogs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Any dog that was presented with dysuria was eligible for inclusion.
