Study Type : Observational
Actual Enrollment : 20 participants
Observational Model: Cohort
Time Perspective: Prospective
Actual Study Start Date : July 2, 2015
Actual Primary Completion Date : February 27, 2016
Actual Study Completion Date : February 27, 2016

Primary Outcome Measures :
  1. change of the hemodynamic profiles including cardiac index on NICOM during the TURP in elderly patients [ Time Frame: change from baseline 1 min before the anesthesia, 10 min after anesthesia, 10 min after surgery, 20 min after surgery, 30 min after surgery, at the end of the surgery ]
    (Cardiac output, stroke volume, Stroke volume index, Total peripheral resistance, heart rate, blood pressure)

Secondary Outcome Measures :
  1. change of the electrolyte [ Time Frame: from expected up to 3 months before surgery for preoperative evaluation to expected up to 3 hours after the end of surgery ]
  2. change of the hemoglobin [ Time Frame: from expected up to 3 months before surgery for preoperative evaluation to expected up to 3 hours after the end of surgery ]
  3. estimated absorbed irrigation fluid during the surgery [ Time Frame: during the surgery ]
    Fluid absorbed = % decrease in sodium x ECF (0.2 x body weight)

  4. incidence of TURP syndrome [ Time Frame: followed for the duration of hospital stay, an expected average of 7 days. ]
