OBJECTIVES: To characterize the hemodynamics comparing thulium laser vaporesection of the prostate with traditional transurethral resection of the prostate.
METHODS: A total of 80 consecutive patients with benign prostatic hyperplasia were randomly assigned into the thulium laser vaporesection of the prostate group or transurethral resection of the prostate group. Transpulmonary thermodilution hemodynamic monitoring was used before and 1 h after surgery to assess patient hemodynamics. Acute complications and treatment efficiency were evaluated after surgery.
RESULTS: There were no statistical differences in age, prostate volume, anticoagulants and International Prostate Symptom Score between the two groups. The postoperative Stroke Volume Index was significantly higher in the thulium laser vaporesection of the prostate group (P = 0.007). The extravascular lung water and intrathoracic blood volume indices differed significantly pre- and postoperatively, and were similar in both groups. Decreases in serum sodium and hemoglobin concentrations after surgery were lower in the thulium laser vaporesection of the prostate group (P < 0.01). Acute complications, and improvements in International Prostate Symptom Score and maximum urinary flow rates, were similar in both groups.
CONCLUSIONS: Transpulmonary thermodilution hemodynamic monitoring provides additional safety measures during surgical procedures. Thulium laser vaporesection of the prostate is associated with fewer hemodynamic changes and provides similar efficacy to transurethral resection of the prostate. Thus, it can be considered a safe and effective procedure.
