Abstract
The renal hemodynamic response to 24 h of unilateral and bilateral ureteral occlusion was studied in female dogs. The renal blood flow rose initially and then decreased to significantly below postobstruction levels in both models. After 24 h, the ureteral pressure was elevated in bilateral ureteral obstruction but was near control levels in unilateral ureteral obstruction, implying increased preglomerular vascular resistance in unilateral ureteral obstruction and increased postglomerular vascular resistance in bilateral ureteral obstruction.
