Scanty urination

Anuria is nonpassage of urine, in practice is defined as passage of less than 100 milliliters of urine in a day. Anuria is often caused by failure in the function of kidneys. It may also occur because of some severe obstruction like kidney stones or tumours. It may occur with end stage kidney disease. It is a more extreme reduction than oliguria (hypouresis), with 100 mL/day being the conventional (albeit slightly arbitrary) cutoff point between the two.

In Chinese medicine, scanty urination points to an excess, such as dampness or heat, obstructing bladder qi; it can also be a sign of deficient fluids.
