hi, Thank you for providing the brief history of you. A detailed assessment of the condition is advised. As mentioned by you, that you are having renal failure and also CHF along with other things like DM for 16/10 years for which you are on insulin and some infection of the kidney. Now, since you are on dialysis, the role of a dialysis and what does it mean has to be understood. Dialysis is a process for removing waste and excess water from the blood and is used primarily as an artificial replacement for lost kidney function in people with kidney failure. Dialysis may be used for those with an acute disturbance in kidney function (acute kidney injury, previously acute renal failure) or progressive but chronically worsening kidney function—a state known as chronic kidney disease stage 5 (previously chronic renal failure or end-stage renal disease). The latter form may develop over months or years, but in contrast to acute kidney injury is not usually reversible and dialysis is regarded as a holding measure until a kidney transplant can be performed or sometimes as the only supportive measure in those for whom a transplant would be inappropriate. The kidneys have important roles in maintaining health. When healthy, the kidneys maintain the body s internal equilibrium of water and minerals (sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfate). The acidic metabolism end-products that the body cannot get rid of via respiration are also excreted through the kidneys. The kidneys also function as a part of the endocrine system, producing erythropoietin, calcitriol and renin. Erythropoietin is involved in the production of red blood cells and calcitriol plays a role in bone formation. Dialysis is an imperfect treatment to replace kidney function because it does not correct the compromised endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal). Now as you knew the few things about dialysis, it is performed to control the kidney infection & also to maintain the normalcy of the body. Once the infection is found under control, you may be asked to stop the dialysis, as during this stage , the body heals on its own. If the healing do not occur and the renal tissues same as it is now, then dialysis will be continued for longer duration, upto what ? It all depends upon the control of the infection.
