The purpose of this study was to compare transurethral resection of the prostate (TURP) versus holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia (BPH) focusing on perioperative thrombin generation and fibrinolysis.Sixty-five BPH patients were prospectively randomly assigned to undergo TURP (n = 32) or HoLEP (n = 33). The prothrombin fragment (PF) 1+2, thrombin-antithrombin complex (TAT), tissue plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) were measured preoperatively, at the 1st day and 3rd day after surgery.PF1+2, TAT, t-PA, and PAI-1 significantly elevated at day 1 and day 3 after surgery (P < .05) and remarkedly decreased from the 1st day to the 3rd day (P < .05). The levels of PF1+2 and TAT were higher in TURP group postoperatively than that in HoLEP group (P < .05). There is no significant difference between 2 groups in regard of t-PA and PAI-1 (P > .05).The activation of thrombin generation and fibrinolysis system were noticed in BPH patients after TURP or HoLEP. TURP may associate with a higher hypercoagulable thrombotic risk than HoLEP.
