Abstract

Transurethral resection of prostate is widely popular, effective and easily performable surgery with the least limitation. It is well known that absorption of the irrigant and its following events are the most important factors determining the condition of the patients postoperatively. We studied the changes in serum electrolyte and osmolarity following transurethral resection of prostate in 78 patients of benign prostatic hypertrophy. We divided the patients into two groups, A and B. group A: those were given non-electrolyte solution only during the operation. group B: those were given electrolyte solution during the operation. We compare the results of each group. We also observe the relationship of these results to the irrigating fluid volume, Operation time and resected weight. Following results were obtained. 1. Serum sodium concentration was decreased in 28 cases of group A (75.6%, avg. 5.96mEq/L). 2. Serum sodium concentration was decreased in 16 cases of group B (43.2%, avg. 5.18mEq/L). 3. Serum osmolarity was decreased in 18 cases of group A (75%, avg. 8.83mOsm/kg). 4. Serum osmolarity was decreased in 14 cases of group B (50%, avg. 6. 78mOsm/kg). 5. These changes in serum sodium concentration and osmolarity showed no significance statistically. 6. These changes in serum sodium concentration and osmolarity showed no significant correlation with the amount of irrigant, operation time and resected weight, statistically.
