This is my personal opinion and it is not a conclusive one. I think that not only urea removal but also many other substances present in blood must be monitored and controlled so that kidneys can work better, and this is very important for diabetic patients.
why is it important to have urea removed from diabetic patients
Urea
As the dialysis fluid has no urea in it, there is a large concentration gradient - meaning that urea moves across the partially permeable membrane, from the blood to the dialysis fluid, by diffusion. This is very important as it is essential that urea is removed from the patients' blood.
urea
the concentration of urea should be kept low in the dialysis fluid because urea is harmful for our body if it is not removed.
By filtration through the kidney.
Kidneys
Urea is removed in the kidneys and sent to the bladder.
Really? Urea and water... Urine
The Kidneys, where the blood/urea thing takes place.
Materials removed from the kidneys are urea and water sugar!
urea
The urea and water that make up urine are removed from the blood in the kidney. This is then passed on to the bladder which will be excreted as urine.
