What Causes Multiple Cyst form on My Children With PKD

No one knows exactly how and why multiple cysts form on the kidneys in polycystic kidney disease (PKD).
Genetics certainly seems to play a part, but if your niece's family has no history of the condition, it is still possible that the genetic change involved could have happened in your niece of its own accord.
PKD can occur in both adults and children. It's more common in adults and often doesn't become apparent until later life.
The cysts gradually enlarge and can go on to interfere with kidney function. This in turn can lead to hypertension (high blood pressure), anaemia, and an increased likelihood of infections and kidney stones.
No treatment can prevent the cysts from forming or enlarging. Micro-Chinese Medicine Osmotherapy is suggested for it helps shrink kidney cyst naturally, which shows no side effects in child, due to its natural functions.
The disease is usually slowly progressive, eventually causing kidney failure. Childhood PKD tends to progress more rapidly and is therefore usually associated with a worse prognosis than that presenting in adulthood.
I am afraid I am unable to comment as to how this affects your niece specifically.
Management of the condition is aimed at the reduction of symptoms and prevention of complications.
A low-salt diet is often recommended in the management kidney disease, and the dietetics department and nephrology unit at your local hospital will be able to advise.
Surgical drainage of a cyst may be required if it is causing a problem with urination or repeated infections.
Surgical removal of one or both kidneys may be required and depending upon progress, treatment of PKD may include kidney dialysis or kidney transplantation.
Sharing experiences and problems by joining a support group can often help to relieve the stress of illness. British Kidney Patient Association aims to help finance patients in need of vital surgery, and increase public awareness of the need for kidney donors.

The association also supplies information about transplantation and dialysis procedures.
