Popis: Objective:To determine the clinical efficacy of abdominal fluid to peripheral blood ratios of creatinine and potassium concentrations to diagnose uroperitoneum in dogs. Design:Records of 13 dogs with confirmed uroabdomen were retrospectively analyzed. Prospective evaluation of 8 dogs with nonrenal ascites provided data for a control population. Setting:Veterinary Medical Teaching Hospital. Animals:Client owned dogs. Interventions:None Measurements and Main Results:Abdominal fluid potassium (mEq/L) and creatinine concentrations (mg/dl) were recorded. Peripheral blood potassium and creatinine concentrations were also recorded. Ratios were calculated based on these values. An abdominal fluid creatinine concentration to peripheral blood creatinine concentration ratio of > 2:1 was predictive of uroabdomen in dogs (specificity 100%, sensitivity 86%). An abdominal fluid potassium concentration to peripheral blood potassium concentration of > 1.4:1 is also predictive of uroabdomen in dogs (specificity 100%, sensitivity 100%). All dogs with uroabdomen had an abdominal fluid creatinine concentration that was at least 4 times normal peripheral blood levels. Conclusion:Abdominal fluid to peripheral blood potassium and creatinine ratios provide a means to diagnose uroperitoneum in dogs without elevated peripheral blood creatinine.
