What condition is characterized by a scant amount of urine?

Oliguria is the term used to describe a condition characterized by the production of a scant amount of urine. It is defined as a reduced urine output, typically less than 400 milliliters per day in adults. This condition can be indicative of various medical issues, including dehydration, kidney malfunction, or blockage in the urinary tract. Recognizing oliguria is vital as it can suggest underlying problems that may require immediate medical attention.

In contrast, hypertension refers to high blood pressure and does not specifically relate to urine output. Hematuria is the presence of blood in the urine, which is unrelated to urine volume but indicates potential bleeding in the urinary system. Polyuria, on the other hand, involves the production of an excessive amount of urine, which is the opposite of oliguria. Understanding these definitions is crucial for distinguishing between different urinary conditions and their possible implications for patient health.
