PKD & Kidney Cysts

Polycystic kidney disease (PKD) is a group of disorders that result from the formation and progressive enlargement of cysts in the kidneys without dysplasia, usually leading to renal failure.

Polycystic Kidney Disease with Swelling in Ankle or Foot

2013-07-10 16:59

Polycystic Kidney Disease with Swelling in Ankle or FootSwelling in ankle or foot usually doesn’t occur in stage 1-2 Polycystic Kidney Disease. However, as PKD cysts grow, this symptom indeed happens to some patients. Then, the question about causes and managements of swollen ankles or feet in PKD needs to solve urgently.


Generally, two causes can contribute to swelling linked with Polycystic Kidney Disease:

● Renal dysfunction: GFR has a close link with kidney function. When kidney functioning tissues are damaged by large kidney cysts, glomeruli can’t filter excess water efficiently. If renal tubular reabsorption function still keeps in a high level, it is easily to cause water and sodium retention, thus leading to swelling.

● Decline of plasma colloid osmotic pressure: With low GFR, a large amount of protein leaks from kidneys to cause low plasma protein level and then plasma colloid osmotic pressure. In this condition, swelling in ankle or foot occurs easily.

How to relieve swelling in Polycystic Kidney Disease?

For PKD patients who have swelling, they should limit the intake of fluid and sodium, otherwise, their condition may aggravate.

In the same, diuretic is often used to increase the kidney output and remove excess water from the body. If possible, kidney experts would like to recommend natural diuretics for kidney disease patients such as: cranberry, celery, dandelion tea, parsley, etc. (Consult the online doctor to find which one is suitable for you.)

If diet modifications and diuretic can’t work very well, patients may need to accept blood purification, namely dialysis, peritoneal dialysis, plasma exchange and CRRT. Correct choice of blood purification technologies can help patients ease swelling efficiently.


Swelling in ankle or foot can reveal more other conditions for people with Polycystic Kidney Disease. Finding out the causes and accepting correct treatment is the best way to avoid more severe problems. Besides the above methods, it is necessary to shrink PKD cysts and improve kidney function.
