Can uremia be without dialysis

summary

Due to the high cost of renal replacement and the difficulty of matching kidney source, dialysis is the first reaction to the treatment of uremia. So how much do people know about dialysis, how dialysis is a workflow, what role does it play, and what disadvantages does it have? I'm afraid most people can't tell. Let's talk about whether uremia can be without dialysis.

Can uremia be without dialysis

First: what is the working process of dialysis? Dialysis refers to the process of solute passing from one side of the semipermeable membrane to the other. Any natural (e.g. peritoneum) or man-made semipermeable membrane can move solutes from one side of the membrane to the other through dispersion and convection as long as the membrane contains pore size through which solutes of a certain size can pass. Hemodialysis is based on the principle of semipermeable membrane, which introduces the patient's blood and dialysate into the dialyzer at the same time, and moves in the opposite direction on both sides of the dialyzer membrane. By virtue of the solubility gradient, osmotic gradient and water pressure gradient on both sides of the semipermeable membrane, the toxin can be removed through dispersion, convection and adsorption; the excess water in the body can be removed through ultrafiltration and osmosis; At the same time, supplement needed substances, correct electrolyte, acid-base balance disorder.

Second: what is the effect of dialysis on the kidney? Dialysis is to work instead of the kidney. When the patient enters the uremic stage, the patient's kidney should be damaged by more than 90%. If there is no alternative treatment, the toxin will remain in the body. The "poison" in the body includes metabolites, drugs and exogenous poisons. As long as its atomic weight or molecular weight is appropriate, it can be removed out of the body through dialysis. Its basic principle is dispersion and convection.

Third: what is the harm of long-term dialysis, long-term renal dialysis, will produce dependence, nephrology experts all said. Dialysis is only an auxiliary tool for the treatment of the kidney, which can only relieve the pain as soon as possible and can not remove the root. For a long time, dialysis will produce dependence on the human body, and it will have side effects on the human body after a long time. Kidney dialysis can save people, but it can't cure them. Dialysis can timely and quickly detoxify the body toxin, but the complications after dialysis are many and serious, as time goes by, it will also be life-threatening.

matters needing attention

If dialysis, the kidney will slowly start to no longer be used, a long time will completely lose function, then there will be no way to treat and repair
