The afferent impulses do not stimulate nerves that go to the kidney and prevent glomerular filtration. The correct statement should be that the afferent impulses stimulate sympathetic nerves that cause constriction of the afferent arterioles in the kidneys, reducing glomerular filtration until the bladder is empty.
