Treatment will depend on the type, symptoms and severity of hyperoxaluria and how well you respond to treatment.
To reduce the amount of calcium oxalate crystal formation in your kidneys, your Mayo Clinic medical team may recommend one or more of these treatments:
- Medications. Prescription doses of vitamin B-6 can be effective in reducing oxalate in the urine in some people with primary hyperoxaluria. Oral preparations of phosphates and citrate help prevent the formation of calcium oxalate crystals. Other medications, such as thiazide diuretics, also may be considered, depending on which other abnormalities are present in your urine.
- High fluid intake. If your kidneys are still functioning normally, your doctor will likely tell you to drink more water or other fluids. This flushes the kidneys, prevents oxalate crystal buildup and helps keep kidney stones from forming.
- Dietary changes. The effectiveness of diet will depend on the cause of increased levels of oxalate. Diet may include restricting foods high in oxalates, limiting salt, and decreasing animal protein and sugar (high fructose corn syrup). This may help to lower urinary oxalate in people with enteric hyperoxaluria or excess dietary intake. Dietary restrictions may not be as important for all people with primary hyperoxaluria. Follow the advice of your doctor.
Kidney stone management
Kidney stones are common in people with hyperoxaluria, but they don't always need to be treated. If large kidney stones are causing pain or blocking urine flow, you may need to have them removed or broken up so they can pass in the urine. Mayo Clinic is experienced in kidney stone treatment and removal and offers several minimally invasive procedures.
Dialysis and transplant
Depending on the severity of your hyperoxaluria, you may eventually lose kidney function. Kidney dialysis may help temporarily, but it doesn't keep up with the amount of oxalate produced. A kidney transplant or kidney and liver transplant can cure certain inherited types of hyperoxaluria (primary hyperoxaluria). Mayo Clinic provides outstanding transplant teams, led by highly skilled surgeons and medical transplant teams experienced in the care of patients with primary hyperoxaluria.
