CHAPTER 97 Urolithiasis

چکیده
Introduction Urinary stones are relatively uncommon in the paediatric age group; however, the prevalence seems to be on the increase and the tendency towards urinary lithiasis in males and females is the same in childhood.1,2 The clinical features are often vague and nonspecific, so a high index of suspicion is usually required for diagnosis. Limited investigations tend to be performed in children presenting with urinary calculi,3 and this may affect the prevalence of urinary stones in children. The prevalence is also affected by race, genetics, diet, and geographic location.4
