If hydrostatic pressure is elevated and protein osmotic pressure reduced then water leaves the Interstium and enters the tubular lumen thus increasing water loss.  These pressure changes are characteristic of a situation where the animal drinks a large amount of water in a short period of time.

If the situation is reversed it results in a decreased urinary output and is often caused by a fall in blood pressure associated with a reduction in ECF.
