With the development of surgical techniques, most of the surgical treatment for BPH is now done using minimally invasive surgical techniques. Only for patients with very large prostate size and combined bladder stones and bladder diverticula will open surgery be considered. Minimally invasive procedures for the treatment of BPH include: transurethral electrodesiccation of the prostate, transurethral prostatectomy, transurethral electrovaporization of the prostate, and laser surgery. Among them, transurethral electroporation of prostate is one of the classics and is widely used in clinical practice. The so-called transurethral electrovaporization of the prostate is when the surgeon uses special surgical instruments to enter the urethra through the urethra to reach the prostate, then cuts off the hyperplastic tissue piece by piece, and finally flushes this tissue out of the body. The main advantages of transurethral resection of the prostate compared to open surgery in the past are as follows: 1. Transurethral resection of the prostate causes less damage to all systems of the patient, so even those patients who cannot tolerate open surgery, such as elderly patients with diabetes, hypertension and heart disease, can still be treated with transurethral resection of the prostate; 2. The procedure time is shorter, and most patients bleed less, so there is almost no need for blood transfusion; 3. Patients recover faster after surgery, they can generally get out of bed on the second day after surgery and can be discharged within a few days, which is something that open surgery cannot even think about.
