The pattern of biopsied renal pathology is similar to that reported recently from other parts of the world with similar biopsy indications.

The pattern of calculous disease changed from a predominantly lower tract site in the mid 1980s to the upper tract in the mid 1990s. Stone composition, urinary risk factors and dietary analysis suggest that diet, dehydration and poor nutrition are the main causative factors of stone disease.

This study shows that VEGF -2578 A-allele and A-carrier genotypes are associated with an increased risk of RCC. In groups with higher incidence of RCC, a screening test for this polymorphism may be recommended in conjunction with other established markers.

The use of ESWL, percutaneous nephrolithotomy and ureterorenoscopy has resulted in treating a large number of children with a short hospital stay and early return to school. Open surgery is reserved only for complex stones.
