Kidney shrinks when large amounts of nephrons like glomeruli and renal tubules are dead. Well then, what does stage 2 kidney shrinkage mean?
Stages of kidney shrinkage
In clinic, we can divide kidney shrinkage into four stages. Here is an introduction. Any questions, please email to email@example.com, and our doctor will reply you within 24 hours. The online consultation is free.
Stage 1: In this stage, the kidney still have normal or mild damage. The glomerular filtration rate (GFR) reduces at least 30 ml/min to 60ml/min. About 20% to 25% kidney function has lost. Yet, they can still remove wastes and maintain fluid and electrolyte balance as well as before. Patients see no symptoms and the creatinine and BUN (blood urea nitrogen) level are both normal.
Stage 2: Patient with stage 2 kidney shrinkage have lost 50% to 70% nephrons. The renal function of concentration and dilution is damaged, resulting in frequent urine, especially at night. Patients may also have anemia, along with increased BUN and creatinine levels. Symptoms such as fatigue, poor appetite, nausea, vomiting, diarrhea or infections present. If left untreated, all these problems will cause further kidney damage, and aggravate kidney shrinkage.
Stage 3: About 70% to 90% kidney function loses. The kidneys cannot keep the balance of water, electrolyte and acid-base balance. Swelling, weakness, concentration difficulty and shortness of breath may occur.
Stage 4: It is also called End Stage Renal Disease (ESRD), or Kidney Failure. More than 90% kidney function fails and many other organs are attacked. Heart, nervous systems, respiratory system, skin and metabolic systems may be all injured. Patients at this stage have high risk of death due to some complications such as heart failure, hydrocephalus, pulmonary edema or hyperkalemia.
As long as you take timely and proper treatment, you can still have chance of developing Kidney Failure in the future. You can get some suggestions from our doctors online.
