What term describes a situation with no elimination of urine?

The term that describes a situation with no elimination of urine is "anuria." Anuria is defined as the absence of urine production, typically indicating severe impairment of kidney function or complete obstruction of the urinary tract. This condition can be critical as it often signifies a serious underlying health issue, such as acute kidney injury, severe dehydration, or urinary tract obstruction.

Oliguria refers to a reduced urine output, which allows for some urine to be produced, while polyuria indicates excessive urine output, often seen in conditions like uncontrolled diabetes. Retention, on the other hand, typically describes a scenario where urine is produced but not adequately expelled from the bladder, which does not convey the complete lack of urine formation that anuria does. Thus, anuria specifically captures the idea of no urine being produced at all, making it the correct choice in this context.
