What condition occurs when the bladder is able to empty itself but no urine being produced by kidneys?

The condition you're referring to is called anuria, which is characterized by the complete absence or significant reduction in urine output. When the kidneys fail to produce urine or produce very little urine, the bladder is unable to empty itself as there is no urine to be stored or passed.

Anuria can be a symptom of several underlying medical conditions that affect the kidneys and urinary tract, such as:

- Severe kidney damage or failure (acute or chronic renal failure)

- Obstruction of the urinary tract, such as kidney stones or tumors blocking the flow of urine

- Severe dehydration, where the body is extremely deficient in fluids

- Advanced stages of certain medical conditions, such as diabetes, heart disease, or liver failure

- Medications that impair kidney function or affect urine output

- Certain systemic disorders that can affect kidney function, such as autoimmune disorders or infections.

If a person experiences anuria or a significant reduction in urine output, it's crucial to seek immediate medical attention, as this condition can indicate a serious medical issue that requires prompt diagnosis and treatment. The underlying cause of the anuria will need to be identified and addressed to restore normal kidney function and urine output.
