Using Haemocoagulase Agkistrodon in Patients Undergoing Transurethral Plasmakinetic Resection of the Prostate: A Pilot, Real-World, and Propensity Score-Matched Study

Objectives. To compare the clinical outcomes of using different hemostatic agents after transurethral plasmakinetic resection of the prostate (TUPKP) in benign prostatic hyperplasia (BPH) patients. Methods. The patients were divided into 5 groups according to the hemostatic agents used after TUPKP, including the haemocoagulase agkistrodon for injection (HCA), hemocoagulase for injection (HC), hemocoagulase bothrops atrox for injection (HCB), ethylenediamine diaceturate injection (EDD), and tranexamic acid (TXA). Propensity score matching was performed based on age, body mass index, prostate volume, hypertension status, fasting blood glucose, smoking, and drinking history. The hospitalization time, bladder irrigation time, indwelling catheterization time, the patency of urine flow, and blood transfusion records were used as outcome indicators to compare the clinical effects of these five agents. Results. We finally matched 65 pairs receiving HCA or HC, 71 pairs receiving HCA or HCB, 38 pairs receiving HCA or TXA, and 29 pairs receiving HCA or EDD. Compared with HC, HCA given during the perioperative period significantly reduced the median hospitalization time [7.00 days (5.00, 8.00) vs. 9.00 days (8.00, 10.00); p < 0.001] and median catheterization time (109.00 hours [88.00, 129.00] vs. 164.00 hours [114.00, 189.00], p < 0.001). Compared with EDD, the median hospitalization time (7.00 days [6.00, 8.00] vs. 10.00 days [8.00, 11.00]; p < 0.001) and median catheterization time (113.00 hours [95.00, 143.00] vs. 160.00 hours [139.00, 168.00]; p < 0.001) were also significant shorter in HCA group. Compared with HCB, median bladder irrigation time (45.00 hours [27.00, 71.00] vs. 49.00 hours [45.00, 72.00]; p=0.04) was shorter in the HCA group. However, there were no statistical differences in outcomes between HCA and TXA. Conclusions. HCA probably has an advantage over HC, HCB, and EDD in reducing the hospitalization time, catheterization time, and bladder irrigation time among BPH patients undergoing TUPKP.
