- Abstract
The experimental study was conducted to evaluate the effect of furosemide on renal Doppler parameters in the diagnosis of chronic unilateral partial ureteric obstruction. Partial ureteral obstruction (UO) was induced by narrowing the left ureter in New Zelland Rabbits (n=10). Resistive index (RI), RI difference (RIΔ) and RI ratio (RIr) values were obtained by Doppler utrasonographic (DU) evaluation of the kidneys preoperatively and the 1st and 4th weeks postoperatively. According to the mean RI value of preoperaitve left kidney, the increase in the mean RI value of the obstructive (left) kidney at the postoperative 1st week was statistically significant (P < .04). After furosemide administration, the mean RI value of the non-obstructive kidney decreased at both postoperative measurement times, and accordingly, a statistical difference was determined between the obstructive and non-absturctive kidneys (P < .002). The mean RI values of the postoperative measurement did not exceed the 0.70 threshold for both direct and diuretic measurements. At the postoperative measurement times, diuretic administration caused the mean RIΔ above threshold value (≥ 0.11) and further increased the RIr, which was above the threshold value (≥ 1.1). The results of this study demonstrate that diuretic administration can increase the diagnostic accuracy of chronic unilateral partial UO by increasing RIΔ and RIr in unilateral high renal RI values that do not exceed the threshold value.
