What is affected by diminished renal excretion related to uric acid?

Diminished renal excretion of uric acid directly leads to increased plasma levels of uric acid. The kidneys play a critical role in filtering and excreting uric acid from the bloodstream; if their function is impaired or the excretion process is reduced, uric acid accumulates in the body. High plasma levels of uric acid can result in conditions such as gout, where uric acid crystals form in joints, causing pain and inflammation.

This accumulation is unrelated to enzyme activity, liver function, or dietary intake of purines. For example, a decrease in dietary purines would lower uric acid levels rather than increase them, and changes to liver function or enzyme activity are not the immediate consequence of renal excretion issues. Thus, the increase in plasma levels of uric acid is the clear and direct result of diminished renal excretion.
