Brief Summary:
The low sodium intake is important for ascites control in liver cirrhosis patients. Therefore, World Health Organization (WHO) recommends reduction of sodium (Na) to 2g/day for adults. The 24-hour urine Na excretion has been regarded as a standard method to estimate the amount of daily dietary sodium intake. However, it is too inconvenient to apply to patients or the general population in practice. For this reason, it has been suggested that a spot urine Na/potassium (K) ratio could be replaced with the 24-hour urine Na excretion. However, the evidence is not sufficient for that. The investigators will evaluate the usefulness of spot urine Na/K ratio to estimate the dietary sodium intake. The investigators will also verify several formulas of estimating the 24-hour Na excretion with spot urine Na, K, Creatinine (Cr).

Condition or disease
Liver Cirrhosis Ascites

Detailed Description:

● Detailed Description:

  1. Measurements: they should be performed for 2 days (the urine collected within 24 hrs)

    • 24-hour urine Na, K and Creatinine (patients were instructed to collect all subsequent urine voids over the next 24-hour period including the first void of the following day.)
    • Spot urine Na, K, Creatinine with the same urine sample in some containers provided to patients. (every urination)
  2. Calculation

    • Na/K Ratio with spot urine Na, K
    • Estimating 24-hour urine Na with spot urine Na, K, Cr by using some formulas.

Primary Outcome Measures :
  1. To evaluate the usefulness of urine Na / K ratio as a clinical indicator to replace the 24-hour urine sodium excretion (mEq/L) in liver cirrhosis patients with ascites. [ Time Frame: After 24 hours of urine collection ]
    Previous studies have reported that the spot urine Na / K ratio is 90 percent accuracy compared to 24hr urine Na excretion. To verify this, measure spot urine Na, K (mEq/L) by using the same sample as the 24-hour sodium and creatinine excretion and confirm with receiver operator characteristic (ROC) curve to find the best cutoff point of spot urine Na / K ratio.
