Study Details

Study Description

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.

Outcome Measures

Primary Outcome Measures

  1. rate of stone recurrence or stone growth [12 months]

    The patients were evaluated at 6 months after the initial treatment for serum chemistry and urinalysis. After 12 months, all patients were evaluated for serum chemistry, urinalysis, 24-hour urine study and plain KUB.
