Diet For Kidney Stones For PKD PatientsKidney stone is one common complication among PKD patients and some patients can even have several stones in their kidneys when they have ultrasound or other renal imaging tests.

In most cases, kidney stones due to PKD are uric acid stone or calcium oxalate stone. Some proper diets can help prevent and treat kidney stones for PKD patients.

For calcium oxalate calculus patients, they should reduce or avoid foods that produce oxalic acid such as spinach, amaranth, water spinach, mustard, etc. Avoid having too much intake of vitamin C. For elderly patients, it is advised that they should have calcium supplement with meals.

For uric acid stones, its incidence can be much lowered if patients avoid eating too much meats and fats. Patients suffering from uric acid stones should reduce the intake of foods that can produce purine such as animal offals, sea products, red meats such as beef and mutton, nuts, etc.

Water intake is also one important prevention measures for kidney stones for PKD patients. It is suggested that kidney stone patients should have more than 4000ml fluid intake to maintain daily urine output more than 1500ml so that to keep the urine diluted and it can help discharge some small-sized kidney stones. Purified water, light tea, juices of orange, lemon and watermelon are all good choices for PKD and kidney stones. Strong tea, coffee, cola and other caffeine-containing drinks should be avoided because caffeine can cause dehydration and promote the secretion of cyst fluid.

For PKD patients, they should also limit the intake of salt and proteins. Low-salt diet has many benefits to PKD patients. It can help maintain urine output, reduce the growth of renal cysts and secretion of cyst fluid, lower the incidence of infections and stone formation, control high blood pressure and reduce injuries caused by high blood pressure.
