Pediatric kidney stones are solid, rock-like crystals that form in the kidneys and block the flow of urine. Kidney stones typically range in size from tiny pebble-like masses to larger stones measuring up to one-half of an inch or more.
Pediatric kidney stones are typically caused by too much calcium in the urine. They occur most often in families with a history of the condition.
Symptoms, Diagnosis and Outlook
Kidney stones may develop in bursts or slowly over time. The most common symptom is sudden and severe pain.
Other symptoms include:
- One-sided back pain that seems to get better and then worse several times during the episode
- Pain that’s mild to severe
- Vomiting and nausea
- Blood in your urine
- Painful urination
Diagnosis of pediatric kidney stones includes:
- Physical exam and review of medical history
- Blood and urine tests
- Radiology studies
Most pediatric kidney stones will pass through your child’s urinary tract and be expelled when he or she urinates. Pain relief is often required and antibiotics may be needed if the stone causes a urinary tract infection. Pediatric kidney stones that do not pass on their own may require surgical removal.
