ABSTRACT
When the kidney fails to perform its homeostatic regulating role and excretory function, serious problems occur. Urine study can provide important information that is of value both in the recognition of the problems and in monitoring the course of the patient who has received a renal transplant or has been subject to hemodialysis. Organ transplantation of kidneys involving identical twins has been utilized for many years, but transplantation has achieved practical utility on a much wider basis with the appearance of various pharmacological agents which have the capability of suppressing the immune reactions of the body. The basic concept of hemodialysis is that of dialyzing the blood against a solution which simulates blood with respect to all of the diffusable components except the waste products which are being removed. The same general factors which establish good results with other urine studies are effective in studies relating to hemodialysis and renal transplantation.
