Thromboelastography in Long-Term Antiplatelet Therapy for Patients Diagnosed with Benign Prostate Hyperplasia Undergoing Holmium Laser Enucleation of the Prostate: A Retrospective Study.

Objective: To compare low- vs high-power HoLEP effects on coagulation in patients on antiplatelet (AP) therapy via thromboelastography (TEG).

Methods: 210 patients was retrospectively analyzed and stratificated into three discrete groups, specifically: Group A (AP therapy, high-power HoLEP, n = 72); Group B (AP therapy, low-power HoLEP, n=73); Group C (no AP therapy, low-power HoLEP, n = 65). Baseline characteristics and coagulation profiles via TEG were compared. Univariate and multivariate analyses were conducted to identify independent risk factors associated with hematuria. Furthermore, parameters such as IPSS, Qmax, post-void residual volume V and PSA levels were recorded during 1year follow-up.

Results: No differences in terms of baseline characteristics across all groups. Significant differences were observed in the duration of enucleation, morcellation, bladder irrigation, post-operative catheterization, length of hospital stay and the extent of hemoglobin reduction (F = 54.06, 8.54, 6.68, 9.24, 17.06, 5.97, p < 0.05). No differences were noted in postoperative hematuria, urine retention, transfusion rates, and SUI (x = 1.082 ; x  = 0.197,; x = 3.981;x  = 0.816, p > 0.05). Univariate and multivariate analyses revealed that prostate volume emerged as an independent risk factor for hematuria (OR 1.080, 95% CI: 1.007-1.158, p = 0.031). Clinical outcomes including Qmax, IPSS, V, and PSA demonstrated significant enhancement during 1 year follow-up.

Conclusion: Compared to HP-HoLEP, LP-HoLEP effectively reduces surgical and subsequent processing times, decreases hospital stay duration, and diminishes hemoglobin decline, offering a viable option without discontinuing AP therapy.
