Conditions We Treat

We see children with many conditions affecting the kidneys, including:


  • Many conditions can cause blood to show up in urine. This is called hematuria (hee-muh-TOOR-ee-uh). Often these conditions do not lead to lasting problems. But because blood in urine may be a sign of serious kidney problems, children with hematuria should see a doctor.


  • A child has end-stage kidney disease if their kidneys no longer work well enough to keep them alive without help. Usually this means kidney function that is less than 15% of normal for a child’s size and weight. Without dialysis or a kidney transplant, end-stage kidney disease causes serious problems and leads to death. The condition is also called end-stage renal disease (ESRD). Read more.


  • Some kidney diseases happen because of problems with genes or chromosomes that are passed down from parent to child. These genetic diseases include polycystic kidney disease (PKD). In PKD, many fluid-filled cysts grow in the kidneys and limit how well they function.


  • Glomerulonephritis (gluh-mer-yuh-lo-nih-FRY-tus) and interstitial nephritis (in-ter-STIH-shul nih-FRY-tus) cause swelling and redness (inflammation) in parts of the kidney. This makes it harder for the kidney to separate wastes and extra fluid from the blood. It can cause swelling (edema), blood in the urine, high blood pressure and tiredness (fatigue). This can sometimes lead to lifelong (chronic) kidney disease.

  • Hemolytic uremic syndrome (hee-muh-LIH-tik u-REE-mik SIN-drome) causes sudden, short-term kidney failure in children. In severe cases, children need dialysis for a while. Most children recover without lasting damage. HUS most often occurs after an infection with the E. coli bacterium. Read more. (PDF)


  • High blood pressure is more common in adults, but children and teens also can develop it. If untreated, high blood pressure can damage many organs of the body over time. These include the heart, brain, kidneys and eyes. The normal range for blood pressure depends on your child’s sex, age and height. Read more about our Hypertension Clinic.


  • Kidney failure happens when the kidneys can no longer remove all of the wastes from the blood. Kidney failure can either be long-lasting (chronic) or sudden (acute). Chronic disease usually develops slowly. Your child may not show any symptoms until the kidneys can remove only a small amount of waste. Children with acute kidney failure sometimes need dialysis treatments until their kidneys begin to work again. Children with chronic kidney failure need regular dialysis or a kidney transplant. Read more.

  • Kidney stones form when solid materials in urine build up in the kidneys and urinary tract. Small stones can pass out of the body on their own. Large stones may cause problems. They can be very painful when they block the kidney or the tubes that carry urine from the kidneys to the bladder. Kidney stones are more common in adults, but children get them, too. We have the only program in Washington state focused on diagnosing and treating children and teens with kidney stones.


  • Nephrotic syndrome happens when large amounts of protein get into the urine, leaving low levels in the blood. Blood proteins act like a sponge, helping water to stay inside your child’s blood vessels. When protein gets into urine, not enough is left in the blood. Water moves into body tissues, causing them to swell.


  • Proteinuria (proh-teh-NYOOR-ee-uh) means that pee (urine) has more protein than usual. Most proteins are too big to go through the kidneys’ filters, so too much protein in urine may be a sign of a kidney problem.

Subspecialties We Offer

  • Seattle Children’s Acute Kidney Injury Clinic screens patients at risk for kidney damage before they go home from the hospital. Kidneys may be harmed by:

    • Certain medicines
    • Low blood flow to the kidneys
    • Infections
    • Very high blood pressure
    • Liver disorders

     Follow-up with the kidney doctor is very important because your child may not show any signs at first. Damaged kidneys are less able to clean the blood. This can lead to a buildup of waste and fluid in the body. “Acute injuries” means the kidneys are suddenly not able to work normally. Children are at higher risk if they have cancer, infections or heart problems, or had a surgery.

  • The caring providers in our Autoimmune Kidney Disease Clinic diagnose and treat babies, children and teens with autoimmune disease that affects the kidneys. At a single visit to our clinic, your child will see doctors specializing in rheumatology and nephrologyRead more.


  • If your child’s kidneys do not work normally, they may need dialysis to filter waste and extra fluids from their blood. Seattle Children’s has the only dialysis unit in the region just for babies, children and teens. We treat children who are staying overnight in the hospital and who come in for dialysis during the day. Our specialists can teach you how to perform dialysis at home safely and how to handle any problems that might come up. Read more.


  • Our Kidney Stones Clinic is the only program in Washington state to focus on diagnosing and treating children and teens with kidney stones. We help get rid of stones your child has now. We also work with you and your child to prevent new ones. Your child can be seen by their entire health team in the same room, at the same time, to get complete care. Our team includes a dietitian plus doctors and nurses with special training in treating the kidneys (nephrology) and the urinary tract (urology). Read more.


  • Seattle Children’s is 1 of the top 5 kidney transplant centers in the United States. For children and teens with kidney failure, we provide care before, during and after kidney transplant. Read more.


  • Seattle Children’s Pediatric Hypertension program is the only program in our region dedicated to evaluating and treating children and teens with high blood pressure. Read more.


  • Renovascular hypertension is high blood pressure due to narrowing of the arteries that carry blood to the kidneys (called renal artery stenosis). Our team of pediatric specialists are highly skilled in diagnosing and treating problems in blood vessels that affect the kidneys. Read more.
