Abstract

Objectives Little is known about the incidence of urolithiasis in childhood renal tubular acidosis (RTAs). The aim of this paper is to study the incidence of urolithisis/nephrocalcinosis in children with RTDs.

Patients and Methods From June 2000 to April 2007, 42 children with suspected RTD were evaluated to determine the type of tubulopathies. Ages at referral ranged from 8 months to 14 years (mean 4.8 years).

Results Urolithiasis or nephrocalcinosis (lithiasis group) were found in 20 patients pa (60%) including 9 patients (27%) with idiopathic hypercalciurias (IH), 5 patients (15%) with cystinuria, and 5 patients (15%) with renal tubular acidosis (4 distal, 1 proximal), and one patient with primary isolated hyperoxaluria.

Conclusion Urolithiasis occurred in 60% of children with RTD in this sample, with IH the most commonly RTD associated with urolithiasis.
