It is important to seek medical care that takes into account the type, symptoms and severity of hyperoxaluria. Treatment will depend on the individual needs and how well the patient responds to treatment.
The primary goal is to prevent or reduce the accumulation of calcium oxalate crystal formation in your kidneys.
- Medications. Prescription doses of vitamin B-6 can be effective in reducing oxalate in some people with hyperoxaluria. Oral preparation of neutral phosphates and citrate also can be effective to help prevent the formation of calcium oxalate crystals. Other medications like thiazide diuretics may also be considered, depending on the abnormalities present in your urine.
- High fluid intake. If you have normal kidney function your doctor will likely tell you to drink more water or other fluids. The extra fluid flushes the kidneys, prevents oxalate crystal buildup and helps prevent kidney stones from forming. Most important — drinking enough fluid will help reduce your chances of a kidney stone.
- Dietary modifications. For patients with enteric or dietary hyperoxaluriaz changes in diet may include restricting foods high in oxalate, limiting salt, decreasing sugar and reducing animal protein such as meat, eggs and fish. Also, it is important to ensure that you are getting enough calcium from food. Dietary restrictions may not be as important for people with primary hyperoxaluria. Follow the advice of your doctor or registered dietician.
Kidney Stone Management
Calcium oxalate kidney stones are common in people with hyperoxaluria, but they don’t always need to be treated. Depending on your diagnosis, you may need nothing more than to take pain medication and drink lots of water to pass a kidney stone. A person with a larger stone or one that blocks urine flow and causes pain, may need a team of urologists who specialize in stone disease to perform a more specialized treatment, such as
- Shock wave lithotripsy. A machine called a lithotripter is used to crush the kidney stone into smaller pieces. The procedure is performed by a urologist on an outpatient basis and anesthesia is used.
- Ureteroscopy. A ureteroscope — a long tubelike instrument with an eyepiece is used to find and retrieve the stone with a small basket or to break up the stone with laser energy. The procedure is performed by a urologist in a hospital with anesthesia and the person usually can go home the same day.
- Percutaneous Nephrolithotomy. In this procedure, a wire-thin viewing instrument called a nephroscope is used to locate and remove the stone through a small incision in the persons back. The procedure is performed by a urologist in a hospital with anesthesia. The person may have to stay in the hospital for several days after the procedure to allow for any residual stone fragments to drain from the kidney into a urine collection bag.
