In which condition would you see a urine output characterized as 'slow and painful'?

The condition characterized by urine output that is 'slow and painful' is stranguria. Stranguria refers to a condition where an animal experiences difficulty in urination, often accompanied by discomfort or pain. This symptom can be indicative of issues such as urinary tract infections, bladder stones, or inflammation of the urinary tract, which can lead to a painful and hesitant urination process.

In contrast, polyuria refers to an increased volume of urine output, which is not associated with pain or difficulty. Oliguria, defined as decreased urine output, may not necessarily involve pain; rather, it indicates that the kidneys are producing less urine than normal. Anuria is a complete cessation of urine production, which signifies a more severe condition but does not typically involve the sensation of pain during the urination process, as there is no urination occurring at all.

Understanding these distinctions is crucial for recognizing urinary conditions in animals and determining appropriate further diagnostics or treatments.
