In children, hypercalciuria is often associated with some degree of hematuria and back or abdominal pain and is also sometimes associated with voiding symptoms.

Microcrystallization of calcium with urinary anions has been suggested to lead to injury of the uroepithelium in children with hypercalciuria. Consequently, when taking the history of the illness, attempt to identify symptoms relating to the urinary tract, paying special attention to the following signs and symptoms:

  • Dysuria
  • Abdominal pain
  • Irritability (infants)
  • Urinary frequency
  • Urinary urgency
  • Change of urinary appearance
  • Colic
  • Daytime incontinence
  • Isolated or recurrent urinary tract infections [2]
  • Vesicourethral reflux [3]
