Brief summary
Extracorporeal shock wave lithotripsy (ESWL) and Percutaneous nephrolithotomy (PCNL) become the therapy of choice for renal stone. Although providing good results, stone recurrence is usually found as the therapies do not change the underlying metabolic abnormality. Among the metabolic disorders, hypocitraturia is an important risk factor for calcium nephrolithiasis. This study evaluate the preventive effects of potassium sodium citrate on stone recurrence as well as stone growth post ESWL or PCNL, in patients with calcium-containing stones.
Interventions
The treated group was given oral potassium-sodium citrate 81 mEq/day The control group received no treatment
