Acute hyponatremia (AH) was defined as a drop in serum sodium (Na) by greater than or equal to 4\u2009mmol\/L within 48\u2009hours of ligation while exaggerated acute hyponatremia (EAH) was defined as a drop greater than or equal to 10\u2009mmol\/L. Among all patients, there was a significant decrease in [Na] at 24\u2009hours (3.26\u2009\u00b1\u20092.77\u2009mmol\/L) and 48\u2009hours (4.98\u2009\u00b1\u20093.74\u2009mmol\/L). Thirty\u2010two patients (52.4%) had AH while six patients (9.8%) experienced EAH.
