PKD, Kidney Function of 17

Illness description: my father has PKD and high blood pressure. My creatinine is very high now and i have at present about 17 kidney functions left. Is it too late for me to treat the disease?
Illness analysis: your father is at present in stage 4 CKD according to his remaining kidney functions, but kidney function of 17 is very close to end stage PKD, therefore timely and proper treatments and home nursings are very necessary for him.
Since the GFR is already very low, doctors usually will give suggestions for dialysis according to GFR level, when it decreases to 15, dialysis will be prepared. So regular tests should be done, to examine and follow your disease progress. And there is any discomforts, you should pay attention, and consult your doctor.
The external application of herbal medicines, as you said, will be needed every day, and 2-3 times per day. These medicines are mainly to treat your cysts, to shrink them. The medicines can arrive at the kidney lesions with the urinary bladder channel, in Chinese medicine, and then act on the lining cells of the kidneys, to restrain the secretion of the cystic fluid, and also increase the permeability of the cyst wall, so the fluid can be discharged out more quickly. From these two ways, the cysts will get smaller and smaller. And the pressure caused by the enalrging cysts will be lessened. And the Chinese medicines is known as treating disease from the root, but it also has low effects, so after your condition become stable, you still need take some medicines home for consolidation treatments.
Your kidney function is very low now, and is near end stage of kidney failure, so we suggest you take cell therapy, to improve the kidney function.
There are some countries to cell therapy at present, but for PKD patients, our chinese medicines take an important role in the treatments for PKD. And for such patients, not a single treatment can improve the patient's condition. We need to combine western medicines, chinese medicines, and cell therapy, and sometimes we still need blood purification methods, together to let the patient's condition become better.
And for the payment, i am not so clear about the procedure in your country, but in China, if we go to a hospital, we need to deposit some money first, to do some tests, some initial treatments, etc. and then like, if patient needs to do a surgery, they need to pay the money first for the surgery, then the doctors will do it for the patient. That's how it works in China. So after you come, you also need to pay some deposit money first, and then, if treatment plan is made for you, you need to pay the money before the treatment starts. Hope you can understand this procedure. IF not, you can tell me, and i will explain it again.
For PKD patients, we have treated many cases, and we also had a survey, about the patients who are treated in our hospital, about their complications, you can read it. For PKD, of course, in every stage, the results will be different. We have some patients, who are treated in early stage, they are still keeping a good kidney function now. And for some later stage patients, if they haven't started dialysis, the treatments can maintain the current condition. And for some end-stage patients, after the treatments, their dialysis may be reduced gradually. So different conditions will have different results. And of course, the whole process needs the cooperation of the patients with our doctors. Then it will achieve the best result.
