Prostate hyperplasia is one of the common diseases in elderly men, and about 75% of the elderly aged 60 to 70 have prostate hyperplasia. The enlarged prostate seriously affects the patient’s quality of life and is poorly treated with medication. The most important thing is that you should consider surgical treatment when the prostate enlargement leads to urinary retention, recurrent meatus hematuria, recurrent urinary tract infections, and complications such as bladder stones, large bladder diverticula, hydronephrosis, and renal insufficiency. Transurethral resection of the prostate (TURP) is the most classic and commonly used minimally invasive intracavitary surgical method for the treatment of BPH. By the end of the 20th century, transurethral electrovaporization of the prostate, plasma electroprostatectomy, and laser (green laser, holmium laser, thulium laser) prostatectomy have emerged, all of which can remove the enlarged prostate and provide patients with a variety of options. The KLS energy platform is the latest generation of equipment for the treatment of prostate enlargement, the procedure retains the basis of TURP surgery, making it basically effortless for the operator to learn, only needing to master TURP surgery to use the KLS. the KLS takes a different energy emitting platform, with its unique boost pulse function, while outputting conventional energy, the system can also output another kind of energy as needed, making cutting, coagulation becomes faster and more effective. At the same time, it solves the problems often encountered with other devices, such as trimming can not be thin cut, the boost pulse function makes the tissue trimming easy and smooth operation. In addition, its impedance feedback function makes the cutting and coagulation wounds slightly yellowish, produces extremely low carbonization and minimal crusting, minimizes the risk of secondary bleeding, and reduces the number of operating steps during surgery, making the procedure easier. All of these result in essentially no intraoperative bleeding in KLS, a clear surgical field at all times, and faster cutting of tissues, resulting in shorter operative times. The most important feature of the KLS energy platform is that the irrigation solution used during surgery is an electrolyte solution, i.e. saline, which is close to the physiological standard of human blood and eliminates the fatal intraoperative dilutional hyponatremia (TURS syndrome). (TURS syndrome), which makes the operation safer. In conclusion, KLS for BPH is an improved upgrade of the traditional TURP procedure and is more than adequate for the treatment of BPH, especially for elderly and high-risk patients with combined medical chronic diseases (e.g., hypertension, diabetes, etc.) KLS makes the procedure safer for patients and provides better postoperative outcomes, making it a safe, efficient and thorough new method for the treatment of BPH in recent times.
