ANATOMY

Detailed explanation-1: -Anuria, sometimes called anuresis, refers to the lack of urine production. This can happen as a result of conditions like shock, severe blood loss and failure of your heart or kidneys. It can also be due to medications or toxins. Anuria is an emergency and can be life-threatening.

Detailed explanation-2: -Anuria is defined as urine output that is less than 100 mL/24 h or 0 mL/12 h. Polyuria is a condition characterized that there is large volumes of urine (at least 3000 mL over 24 h). Many factors affect the urine volume. The 24 h urine amount of the normal person is about 1000–2000 mL.

Detailed explanation-3: -Oliguria occurs when the urine output in an infant is less than 0.5 mL/kg per hour for 24 hours or is less than 500 mL/1.73 m2 per day in older children. Anuria is defined as absence of any urine output. An important point to remember is that healthy newborns may have no urine output for 24 hours after birth.

Detailed explanation-4: -The exact treatment for anuria depends on the underlying condition that’s causing it. Kidney disease may be treated with dialysis to remove fluids and waste. Ureteral stents may also help collect urine. A kidney transplant is considered a last resort.

Detailed explanation-5: -Bellomo, in his chapter for Oh’s Manual, lists the following “modern” indications for dialysis in the ICU: Oliguria (less than 200ml in 12 hours) Anuria (0-50ml in 12 hours)
