Abstract: Objective: To evaluate the procedure of transurethral bipolar plasmakinetic enucleation for treatment of benign prostatic hyperplasia(BPH).Methods: A total of 40 patients with BPH were performed transurethral bipolar plasmakinetic enucleation of BPH.Results: The operation time ranged from 55 to 155 minutes(95 minutes on the average);perioperative blood loss was 80 to 600 ml(180 ml on the average);the average weight of resected prostate was 67.2 g.All the cases were followed up for 6 to 18 months.No transurethral resection syndrome or permanent urinary incontinence occurred.The maximum flow rate and international prostate symptoms score were significantly increased.Conclusions: Transurethral bipolar plasmakinetic enucleation is especially suitable for large prostate.It has many advantages such as thorough excision of the prostate,less blood loss in operation,less operation time and complication,higher security and quicker recovery.
