  1. Etiological and clinical patterns of urolithiasis in Turkish children.

    Article - En anglais


    To evaluate the clinical and etiological characteristics of childhood urolithiasis in Turkey.


    Ninety-two children with urolithiasis were studied retrospectively according to clinical patterns and etiological factors between January 1990 and January 1995.


    The age range of the patients was from 2 months to 14 years (mean age 6.9 years), and there was a male/female ratio of 1.6. The onset of the disease was earlier in boys than in girls.

    The most striking features were the initial admission of 14 (15.2%) children after the development of chronic renal failure and that most of them (64.3%) had infection stones.

    The stones were localized in the upper urinary system in 68.5% of the patients ; bladder stones were rare (10.9%). The recurrence rate at presentation was 15.2% in all patients.

    As etiological factors, an anatomical defect was found in 30.4% of the patients, infections in 31.5%, and metabolic disorders in 26.% ; 11 (12.0%) of them were classified as idiopathic.

    The earliest presentation was seen with metabolic and infection stones and the highest recurrence rate (37.5%) in patients with metabolic stones.


    Childhood urolithiasis is a serious problem in Turkey.

    In order to prevent the development of end-stage renal failure and to improve the patients'quality of life, more efforts should be made with respect to early diagnosis and management of renal stones and urinary tract infections.
