Abstract

In order to assess the glomerular filtration responses to acute ureteral obstruction in the dog we employed an established method that does not require timed urine collections. Our results show a 57 per cent increase in renal blood flow (baseline: 203.8 ± 50.9 vs. 319 ± 69.4 ml./min. at 105 minutes; no. = 7) that was associated with a monophasic decrease in filtration fraction to -70 per cent at 120 minutes (0.26 ± 0.025 vs. 0.08 ± 0.007) and an increase in ureteral pressure to 63.1 ± 6.1 mm. Hg at 120 minutes. A biphasic GFR response was noted with an initial small increase (baseline: 32.5 ± 7.5 vs. 36.3 ± 11.0 ml./min. at 2 minutes) followed by a continual decline to -55 per cent at 120 minutes (to 14.5 ± 2.6 ml./min.). This investigation has confirmed the results of micropuncture studies showing maintenance of GFR early after complete ureteral ligation.
