Medullary Sponge Kidney

Medullary Sponge Kidney (MSK) Nephrologists in Virginia

Medullary sponge kidney (MSK) is a congenital disorder in which tiny cysts develop in the urine-collecting tubules of the kidneys. Although present from birth, symptoms often don’t appear until adulthood. Our board-certified specialists are experts in diagnosing and managing this complex condition, offering a compassionate approach to guide you through prevention and treatment.

What are the Symptoms of MSK?

The cysts in the kidneys can disrupt the normal flow of urine, allowing calcium and other minerals to accumulate and form stones. These MSK stones cause symptoms similar to other kidney stones, including severe pain in the side or back, blood in the urine, and recurring urinary tract infections.

Effective Management and Prevention for MSK in Virginia

Treatment for medullary sponge kidney focuses on preventing new stones and managing existing symptoms. This usually includes a very high fluid intake to dilute the urine and to avoid mineral buildup. Our specialists may also recommend dietary changes and, in some cases, prescribe medication to help reduce the amount of calcium or other stone-forming substances in the urine.

Frequently Asked Questions About Medullary Sponge Kidney

Can medullary sponge kidney get worse over time?

Medullary sponge kidney (MSK) is a congenital condition, meaning it develops before birth, but it does not typically progress in the same way as many other kidney diseases. The condition itself often remains stable; however, recurring kidney stones, urinary tract infections, or calcium buildup can lead to ongoing symptoms if left unmanaged. Regular follow-up with a nephrologist can help monitor kidney health, reduce complications, and create a personalized prevention plan.

How is medullary sponge kidney diagnosed?

Many people discover they have medullary sponge kidney after being evaluated for frequent kidney stones or repeated urinary tract infections. Your nephrologist may recommend imaging studies, such as a CT scan or specialized X-rays, to identify the characteristic changes within the kidney’s collecting ducts. Blood work and urine testing may also be used to evaluate kidney function, identify mineral imbalances, and determine why stones continue to develop.

Can lifestyle changes help manage medullary sponge kidney?

Yes. Staying well hydrated is one of the most effective ways to help reduce the risk of kidney stone formation. Depending on your individual health needs, your nephrologist may also recommend dietary modifications, reducing sodium intake, or medications that help lower the concentration of stone-forming minerals in the urine. Because every patient is different, treatment plans are tailored to your specific symptoms, stone history, and overall kidney health. Working closely with an experienced nephrologist can help you manage symptoms, reduce future complications, and protect long-term kidney function.
