1. Massive cortical necrosis can result in permanent anuria.

2. Risk factors included old age, oliguria or anuria ARF, hypercatabolism ARF, severe infection, MOF, respiratory failure, liver failure, high blood urea nitrogen, and delayed dialysis.

3. Results The reasons that led to oliguria or anuria early after transplantation were acute rejective reaction(55.9%), acute renal tubular necrosis (38.2%) and accelerated rejective reaction(5.9%).

4. Objective To review the diagnosis and treatment of the children's reflex anuria.

5. Methods: Clinical findings of 46 cases of acute urinary tract obstructive anuria were analysed retrospectively.

6. Objective : To evaluate the role of ureteroscopy for acute urinary tract anuria.

7. Burns: to reduce local oedema and to prevent oliguria from progressing to complete anuria.
