Abstract：Objective To explore the efficiency and safety of the octagonal en-bloc of plough-shaped electrode(Dayu Scalpel)for transurethral plasmakinetic enucleation of prostate in the treatment of benign prostatic hyperplasia(BPH)patients.Methods A retrospective analysis was conducted on the clinical data of the 1st to 30th BPH patients who were treated with oc-tagonal en-bloc of plough-shaped electrode(Dayu Scalpel)for transurethral plasmakinetic enucleation of prostate with at the Af-filiated Suzhou Hospital of Nanjing Medical University from October 2023 to December 2023.Patients were divided into three groups(A,B,C)based on the sequence of surgery,with each group consisting of consecutive sets of 10 patients.Perioperative data,postoperative complications and clinical outcomes were compared among the groups.Results There were no statistically significant differences in age,body mass index(BMI),prostate volume,residual urine volume,the maximum urine flow rate(Qmax),prostate specific antigen(PSA),international prostate symptom score(IPSS),and quality of life(QoL)among the three groups(P＞0.05).The enucleation efficiency in Group B was significantly higher than that in Group A([1.84±0.45]g/min vs[0.97±0.39]g/min),P＜0.05).However,there was no statistically significant difference in enucleation efficiency between Group C([2.26±0.63]g/min)and Group B(P＞0.05).There were no statistically significant differences in enucleated gland weight,enucleation rate,catheterization time,bladder irrigation time,postoperative hospital stay and decrease in hemoglo-bin among the three groups(P＞0.05).All patients were followed up for 3 months after surgery.The residual urine volume,Qmax,IPSS and QoL of the three groups improved significantly(P＜0.05).But there were no statistically significant differences among the three groups(P＞0.05).There were no statistically significant differences in the postoperative immediate urinary control rate among the three groups(90.0％[9/10]vs 90.0％[9/10]vs 100.0％[10/10],P＞0.05).No stress urinary incontinence,re-current hematuria or bladder neck contracture occurred at three months postoperatively.Conclusions The octagonal en-bloc of plough-shaped electrode(Dayu Scalpel)for transurethral plasmakinetic enucleation of prostate is effective with good safety.
