title: Evaluation of changes in serum concentration of sodium in a transurethral resection of the prostate.
abstract: OBJECTIVE
  The purpose of this study was to evaluate changes in serum electrolytes during Transurethral resection of the prostate (TURP) and to evaluate the degree of correlation of hyponatremia and the factors that affect the incidence of TURP syndrome and to show the impact of the duration of the procedure on the severity of hyponatremia due to absorption of irrigation fluid in the systemic circulation.
  
  
  METHODS
  This study examined 60 male patients planned for elective TURP. The level of serum electrolytes are determined by taking venous blood samples preoperatively and Postoperatively and when the duration of the operation was longer than 60 minutes, the level of serum electrolytes was determined intraoperative. The amount of used irrigation fluid, the weight of resection prostate, and duration of surgery, were also followed. Patients were divided in two groups according to the length of the surgical procedure: Group 1 (30-60 min) and Group 2 (> 60 min).
  
  
  RESULTS
  Statistically significant reduction of serum sodium and the elevation of the potassium level in serum observed postoperatively and was directly proportional to the volume of of the used irrigation fluid, the duration of the procedure and volume of the resected prostate.
  
  
  CONCLUSIONS
  To evaluate changes in serum electrolyte during TURP is simple and economical method for the indirect estimation of irrigation fluid absorption into the systemic circulation during TURP and opportunity for early identification of TURP syndrome.
