Abstract
Objective: To evaluate the changes of postoperative serum sodium concetration in patients undergoing percutaneous nephrolithotomy when sorbitol 3% has been selected as irrigation fluid; and to correlate the change with volume of irrigation fluid and the duration of procedure. Subject and method: A prospective study carried out on 100 patients with renal stones larger than 2cm treated by percutaneous nephrolithotomy (PCNL) from December 2013 to December 2016 at 108 Military Central Hospital. Serum sodium concentration were measured before the operation at the first day after the operation. Data analysis was done using SPSS 22.0. Paired T tests were used to compare postoperative serum sodium and their preoperative values. Correlation of the change with total volume of irrigation fluid and the duration of procedure were performed using the Pearson’s correlation coefficient. Result: There was a significant decreased in mean Na+ (137.83mmol/l to 134.41mmol/l) in the first postoperative day as compared to that of the preoperative values (p<0.001). No significant correlation was observed with total volume of irrigation fluid (r = 0.197, p=0.05) and with duration of operation (r = 0.155, p=0.125). Conclusion: This study reveals that there is a significant decreased in Na+ during PCNL in the first postoperative day. No significant correlation was observed with total volume of irrigation fluid and the duration of operation.
