Benign prostatic obstruction (BPO) is the main reason to cause lower urinary tract symptoms (LUTS) in aged male. Oral medications, such as,α1-adrenoceptor antagonist and 5α-reductase inhibitors are the mainstay treatment options. However, some patients can not tolerate long-term use, due to either side effects or limited efficacy. Though transurethral resection or enucleation of prostate usually achieve significant symptom improvement, it's an end stage procedure and it is only reserved for carefully selected patients.~The development of focal ablative therapy yields minimally invasive treatment option for primary tumors such as the liver, lung, pancreas, kidney, and prostate. Among the novel techniques are cryoablation, radiofrequency ablation (RFA), microwave ablation, and high-intensity focused ultrasonography. Irreversible electroporation (IRE) is a one of the ablation modalities using electric pulses to create nanoscale defects in the cell membrane. IRE is not dependent on thermal energy and is therefore causing minimum damage to the blood vessels, nerves and tissue architecture. The present is a randomized, controlled trial, with a main purpose of looking into the safety and feasibility of irreversible electroporation for patients with benign prostatic obstruction.
