The term used for decreased urination is oliguria. Oliguria is defined as the production of urine that is less than 400 milliliters per day in adults. It indicates a reduced urinary output and can be a sign of underlying health issues, such as dehydration, kidney problems, or urinary tract obstruction. Recognizing oliguria is crucial in nephrology, as it may require further assessment and intervention to address the underlying cause.

In contrast, the term polyuria refers to an increase in urine output, typically above 2.5 to 3 liters per day, often seen in conditions like diabetes mellitus or diabetes insipidus. Anuria signifies the complete absence of urine production, defined as urine output less than 100 milliliters per day, which is a more severe condition than oliguria. Hematuria indicates the presence of blood in the urine, which is unrelated to the quantity of urine produced. Understanding these terms is essential for effective assessment and management of patients with renal complications.
