Understanding Renal Failure
Renal failure is a condition that can result in oliguria, which is a decreased urine output. However, it differs from pre-renal kidney failure as it involves damage to the kidneys themselves. Various factors can contribute to this damage, such as blood clots forming in and around the kidneys, lupus, infections, toxins, certain medications, and scleroderma. Additionally, if the kidneys experience prolonged loss of blood flow for more than four hours due to pre-renal causes, it can also lead to kidney damage.
Understanding Post-Renal Kidney Failure
Post-renal kidney failure is a condition characterized by the body’s inability to eliminate urine effectively, leading to a reduction in urine output, medically known as oliguria. This type of kidney failure occurs when there is a blockage that prevents the waste product from leaving the body, despite the kidneys producing it.
Several factors can cause post-renal kidney failure, including the presence of bladder, prostate, colon, or cervical cancer. Additionally, kidney stones or blood clots in the urethra can also contribute to this condition. When urine cannot be excreted due to the blockage, it can accumulate and flow back into the kidneys. This process not only increases the risk of infection but also causes significant damage to the kidneys.
