Final answer:
Urgent dialysis is not indicated in patients with AKI when there is pre-renal uremia or anuria due to acute nephritis.
Step-by-step explanation:
In patients with AKI, urgent dialysis is not indicated when there is pre-renal uremia or anuria due to acute nephritis. Pre-renal uremia refers to an increase in blood urea levels (>300 mg/dl) caused by conditions prior to kidney disorders. Anuria is the absence or decrease in urine production and is observed in acute renal failure and nephritis.
