Abstract
Background: Idiopathic hypercalciuria is a group of diseases which can
be manifested with urinary symptoms. Its importance is due to high
prevalence, recurrent infections, and stone formations which are often
asymptomatic.
Objective: The objective of this study was to determine the prevalence of
Idiopathic Hypercalciuria in children with urinary system related
symptoms attending Pediatric Nephrology Clinic & General Pediatric
Clinic at Fayoum University Hospital from June to December 2019.
Methods: This descriptive cross-sectional study was done in2019 at
Fayoum University Hospital on 206 children who were between 2 to 12
years old. Random morning urine samples was collected from all the
patients for measurement of Ca/Cr levels. Hypercalciuria is defined as
urinary calcium excretion rate that is greater than 4 mg/kg per 24 hours in
a child older than two years of age.
Results: We studied 206 children including 32 (15.5%) had idiopathic
hypercalciuria. Prevalence of idiopathic hypercalciuria was 46.9% in
children with urinary tract infection, 12.5% and 6.3% in children with
microscopic and macroscopic hematuria respectively. In children with
dysuria, there were 90.6%, and34.4%, in children with kidney stone
which was confirmed with sonography, 0% in children with urinary
incontinence.
Conclusion: Hypercalciuria can be presented with different symptoms
associated with urinary symptoms. Therefore, it is recommended to check
the urinary calcium level in children with urinary symptoms with no
definite etiology.
