What percentage of AKI cases is due to post-renal causes?

5-10%
20-25%
30-35%
50%

The correct answer is: 5-10%

Post-renal acute kidney injury (AKI) is typically caused by factors that obstruct the flow of urine, leading to increased pressure in the kidneys and reduced function. The correct range of percentage for post-renal causes of AKI is indeed found to be about 5-10%. This lower percentage reflects the relative frequency of post-renal causes when compared to pre-renal and intrinsic renal causes, which are more common in the overall landscape of AKI. Post-renal obstruction can be caused by conditions such as urinary tract obstruction due to kidney stones, tumors, or an enlarged prostate. However, these scenarios are less prevalent than the physiological derangements found in pre-renal conditions (such as volume depletion) or intrinsic renal damage (like acute tubular necrosis). Thus, recognizing that post-renal causes account for a smaller fraction of AKI cases helps to guide effective assessment and management strategies in nephrology nursing.
