  • EFFECT OF THROMBOXANE INHIBITION ON RENAL BLOOD-FLOW IN DOGS WITH COMPLETE UNILATERAL URETERAL OBSTRUCTION JOURNAL OF UROLOGY Loo, M. H., MARION, D. N., Vaughan, E. D., Felsen, D., Albanese, C. T. 1986; 136 (6): 1343-1347

    Abstract:

    The effect of the thromboxane synthetase inhibitor OKY-046 on renal blood flow and ureteral pressure in awake dogs during 18 hours of complete unilateral ureteral obstruction was studied. OKY-046 was infused continuously throughout the period of obstruction and post-release. Renal blood flow and ureteral pressure were constantly monitored during the study. Urinary thromboxane B2 and prostaglandin E2 excretion served as markers for inhibition of renal thromboxane A2 synthesis. The triphasic relationship between ipsilateral renal blood flow and ureteral pressure previously found following unilateral ureteral obstruction was observed despite OKY-046 infusion. Inhibition of ipsilateral urinary thromboxane B2 excretion was greater than 90% compared to control while ipsilateral urinary prostaglandin E2 excretion was not consistently decreased showing specific thromboxane inhibition. These results suggest that urinary thromboxane B2 may serve as a useful marker for determining the effects of inhibition on renal thromboxane A2 production. At the level of inhibition of thromboxane synthesis achieved we did not observe any change in the late decrease in renal blood flow which is typically seen with chronic unilateral ureteral obstruction.
