What does oliguria indicate?

Oliguria indicates decreased urine output. This condition is characterized by the production of significantly less urine than normal, typically less than 400 milliliters per day in adults. It can be a sign of underlying health issues, such as dehydration, kidney dysfunction, or obstruction of the urinary tract. In the context of oncology, oliguria may be especially relevant when considering the effects of certain cancer treatments, medications, or the metabolic demands of the patient.

The other options do not accurately describe oliguria. Excessive urination refers to polyuria, which is the opposite condition, while the presence of blood in urine is known as hematuria. A contagious skin disease is unrelated to urinary output. Understanding the specific terms related to urine output is crucial, especially in oncology, where kidney function can be significantly impacted by treatment regimens or the disease process itself.
