Treatment of Hypouricemia with Kidney Stone Disease in Renal Hypouricemia (RHUC)

Clinical Scenario

Renal hypouricemia (RHUC) is a condition in which impaired uric acid reabsorption in the kidney leads to abnormally low serum uric acid levels. A recognised complication is the development of urolithiasis — urinary stones — which requires active clinical management.

Comorbidity: Kidney Stone Disease

When RHUC is complicated by urinary stones, clinicians should address the stone-forming tendency directly. Adequate fluid intake is recommended as a preventive measure. The treatment approach targets urinary chemistry to reduce the conditions that favour stone formation.

Treatment Approach (partial)

Management involves urinary alkalization — a specific class of citrate-based compounds is the cornerstone of therapy for the urinary stone complication in this setting.

Physicians should treat patients appropriately if they suffer complications of RHUC, such as exercise-induced acute kidney injury (EIAKI) or urinary stones.

For urinary stones, urinary alkalization using citrate compounds is an effective therapy, and drinking plenty of fluids is recommended for prevention.
