I can tell you about the treatment of chronic kidney disease
in allopathic system of medicine which i practice.
You need to get some tests about kiney finction called RFTs or renal function tests of your blood to know the stage of kidney failure (stage 1 - 5).
To know the cause of kidney disease you need some more tests of blood, urine , ultrasonography
of kidneys and urinary system
This would decide if the condition is treatable or curable and if you require only medicinal treatment or some form of dialysis
(a process of purifying blood through a special machine) is required .
In case the kidney failure is very advanced and irreversible, a kidney transplant
is also possible.
