ABSTRACT

A study of 100 cases of nephrolithiasis between 3 to 15 years of age is reported. Seventy four cases were more than 10 years old. The common presenting symptoms included abdominal pain (69%), burning micturition (23%), gross hematuria (4%) and unexplained pyrexia (6%). Associated urinary tract malformations were found in 16 cases. Twenty four had struvite calculi. Urinary infection with Proteus mirabilis was found in 23 children and idiopathic hypercalciuria in 31 cases. Following surgical removal, either percutaneously or by open surgery, 8 patients had residual calculi and in 6 cases recurrence occurred.
