Mechanism of renin release during acute ureteral constriction in dogs.

The relationship between renal arterial pressure and renin release was examined in anesthetized dogs during complete or partial ureteral constriction. During complete ureteral occlusion ureteral pressure rose to 95+/-4 mm Hg and renin release increased from 1.7+/-0.7 to 22.3+/-3.1 mug/min; renal blood flow (RBF) was not significantly changed. Renin release… CONTINUE READING
