Among other things, the kidneys maintain the balance of fluid and electrolytes in the body and regulate the excretion of waste products

Indwelling urinary catheter (IUC)

An indwelling urinary catheter (IUC) is a tube inserted into the bladder via the urethra which makes it possible to monitor the amount of urine produced each hour and each day.

Fluid balance

Fluid balance in the body is checked daily so that the correct amount of fluid and electrolytes are administered.


Weight is checked regularly to ensure that an excessive amount of fluid does not accumulate in the body.


Diuretics are administered to eliminate excess fluid in the body.


Dialysis treatment is provided in the event of acute renal failure, when there is too much fluid in the body or in the event of serious poisoning. The treatment is administered via a dialysis machine. The blood circulates via a dialysis catheter inserted into a blood vessel to the dialysis apparatus through a filter which removes waste and liquid from the blood.
