What medical term describes no urine output?

The term that describes no urine output is anuria. Anuria is defined as the absence of urine production, typically meaning that the kidneys are not producing any urine, which can be due to various medical conditions such as acute kidney failure, severe dehydration, or urinary obstruction.

Understanding this medical terminology is essential for professionals in the healthcare and mortuary sciences, as it can relate to a patient's overall health, potential cause of death, or various medical conditions that may be encountered in the profession.

The other terms, while related to urine output, denote different conditions: oliguria refers to a significantly reduced urine output, whereas polyuria indicates an excessive amount of urine production. Amenuria is not a commonly used term in modern medical language and can cause confusion, which is why anuria is the correct and most widely accepted term for the complete absence of urine output.
