Management of Small, Non-obstructing Renal Stones in Adults With Recurrent Urinary Tract Infections.

The management of small, non-obstructing renal stones in adults with recurrent lower urinary tract infections remains unclear. Whereas for larger or obstructing stones the decision to intervene becomes clearer, for stones smaller than 5 to 6 mm the decision to intervene requires consideration of multiple factors. This review describes these factors, including history, imaging, laboratory studies, as well as a comprehensive review of the literature. It remains of utmost importance that patients have additional possible etiologies appropriately evaluated and managed prior to intervention for their small renal stones.
