Which term describes zero urine production?

Explanation:
Zero urine production is called anuria. This term means the kidneys are producing little to no urine, with typical thresholds around less than about 100 mL per day. Oliguria, by contrast, is a reduced amount of urine—not zero—often defined as roughly under 400–500 mL per day. Polyuria is the opposite: excessive urine production, usually more than about 2 liters per day. Dysuria refers to painful or difficult urination, which is about the sensation or experience of urination rather than the volume. Anuria signals a serious issue, such as severe kidney injury, extensive urinary tract obstruction, or profound dehydration with renal hypoperfusion, and requires urgent evaluation.
