Answer

Most urinary calculi develop in persons aged 20-49 years. Peak incidence occurs in people aged 35-45 years, but the disease can affect anyone at any age. Patients in whom multiple recurrent stones form usually develop their first stones while in their second or third decade of life. An initial stone attack after age 50 years is relatively uncommon.

Nephrolithiasis in children has historically been rare, with approximately 5-10 children aged 10 months to 16 years being seen annually for the condition at a typical US pediatric referral center. Over the last 25 years, however, the incidence of nephrolithiasis in children has increased by approximately 6-10% annually. In adolescents, the incidence has reached 50 per 100,000. [18]
