The kidney is a well-vascularised organ and suitable to be evaluated by Doppler ultrasound, which is a non-invasive technique that can be used to estimate the renal vascular resistance by calculation the resistive index (RI) and pulsatility index (PI). RI and PI can be calculated from renal arteries, interlobular arteries, and arcuate arteries. In human patients, renal vascular resistance has been reported to be associated with the early hypertensive renal damage and also to correlate with the systemic blood pressure. The study was conducted over a two year period (December 2012- December 2014) in the Department of Internal Medicine of the Faculty of Veterinary Medicine Bucharest, on twenty eight dogs with different renal diseases. Significant differences were found between renal vascular resistance and red blood cell count, creatinine and blood urea nitrogen. Increased intrarenal vascular resistance may be associated with hypertension as a result of renal disease. The aim of this study was to assess renal vascular resistance in dogs with renal disease and the relation between renal RI and PI with systolic blood pressure in dogs with different renal diseases.
