THE ROLE OF HYPERCALCIURIA IN A SUBGROUP OF DYSFUNCTIONAL VOIDING SYNDROMES OF CHILDHOOD

Abstract

Purpose: Idiopathic hypercalciuria is believed to be the cause of a variety of urinary tract complaints in clinical pediatrics, including urinary frequency, urgency, and/or dysuria, often associated with gross or microscopic hematuria. In children noncalculous manifestations of idiopathic hypercalciuria are reportedly more common than urolithiasis. We determine the use of the calcium-to-creatinine ratio for the evaluation of different subsets of functional voiding disorders.Materials and Methods: We retrospectively evaluated 288 patients with functional voiding disorders during the last 8 years. Patients presenting with isolated urinary tract infection were not included in the study. A thorough history with emphasis on voiding patterns was elicited and a routine urinalysis was performed in all patients. Patients were divided into 5 groups of 22 with total gross hematuria and dysfunctional voiding pattern, 102 with microhematuria and dysfunctional voiding pattern, 66 with isolated childhood daytime frequen...
