What potential effect can IV contrast agents have on urine production?

IV contrast agents can increase urine output primarily due to their high osmolarity. When contrast media are administered intravenously, they often lead to an increase in the osmotic pressure in the renal tubules. This increased osmotic load can result in a diuretic effect, stimulating the kidneys to excrete more urine as they attempt to manage and eliminate the excess solutes.

The body's response to the presence of contrast agents includes increased filtration through the glomeruli, which leads to higher levels of urine production. Moreover, the effect can be more pronounced in patients with healthy renal function, where the kidneys effectively filter and void these substances.

While some patients may experience a decrease in urine output due to dehydration, acute kidney injury, or other complications, the primary action of the contrast agent on a physiological level relates to increasing renal excretion. Therefore, the correct interpretation of the influence of IV contrast agents on urine production is that they can lead to an increase in urine output.
