Why Dialysis Prevent Patients from Urinating Normally

When the kidneys are no longer working effectively, waste products and fluid build up in the blood. Dialysis takes over a portion of the function of the failing kidneys to remove the fluid and waste products. Kidney transplantation can more completely take over the function of the failing kidneys.

Dialysis and kidney transplantation are treatments for severe kidney failure, also called renal failure, stage 5 chronic kidney disease, and end-stage renal disease.

Dialysis, a procedure that uses a special machine to replace the kidneys in filtering waste from the bloodstream, may reduce the daily urine output that a person normally produces. This happens because as the blood is filtered during dialysis, fluid is removed, thus reducing the kidneys’ traditional role. As a result many dialysis patients produce very small amounts of urine. However, dialysis does not prevent someone from urinating normally; it only reduces the total urine output, so that he or she may only need to urinate once a day, which is not dangerous.

Some dialysis patients produce as little as one cup or less of urine each day, though urine volume is usually dependent on the underlying cause of kidney failure. Some patients continue to produce normal volumes of urine, which helps to manage their fluid balance. You should be able to get more information from your grandmother’s doctor, a nephrologist.
