    What Will Happen in CKD Stage 4 of Polycystic Kidney Disease

    2014-05-20 07:52| Font Size A A A

    What Will Happen in CKD Stage 4 of Polycystic Kidney DiseasePolycystic kidney disease means there will be countless cysts growing in patient’s kidney, and they will be bigger and bigger, which can damage patient’s kidney structure gradually. There are five stages of PKD, and stage 4 PKD means patient’s kidney function is damaged severely.

    What is stage 4 PKD?

    PKD is a chronic renal disease, and CKD is divided into five stages according to patient’s GFR. When patients are in CKD stage 4 of PKD, their GFR range is 15~29ml/min. However, for healthy people, their GFR level can reach 120ml/min. So, stage 4 PKD patients’ kidney function is very low.

    Kidney is an organ which is in charge of our body’s metabolic balances of electrolytes, fluid and acid-base by removing out the metabolic wastes and excess fluid patient’s body. Thereby, when PKD patients’ kidney function is damaged severely, many metabolic disorders will appear, which can cause many health problems.

    What will happen in PKD stage 4?

    As we have said, PKD patients’ kidney function will be reduced gradually due to their enlarged renal cysts. Thereby, stage 4 PKD patients’ kidney size is much bigger than normal, and lots of nephrons are damaged at this point.

    In fact, there are about one million nephrons in kidney, which are in charge of filtering our blood and removing out the metabolic wastes from our body. Thereby, when patient’s GFR is reduced obviously, that means lots of nephrons have been damaged.

    For patients with stage 4 PKD, they can have many complications, like hypertension, gout, anemia, kidney stone, renal osteopathy, etc. Besides, when patients’ kidney function is too low to keep their body health, their doctors will recommend them dialysis to prolong their lifetime, which is a kidney replacement therapy. In fact, when patients have about 15% remaining kidney function, dialysis will be recommended, and it is when patients are going into stage 5. Thereby, patients with stage 4 PKD may need dialysis in the near future.
