Prostatic hyperplasia (BPH for short) is not unfamiliar to many middle-aged and older men, I’m afraid. Many elderly men repeatedly have urinary frequency and urgency, dribbling urine, delayed urination or even difficulty in urination, and have to go to the toilet 2 to 3 times a night or even more, which seriously affects their daily life and even work. Some patients who have difficulty urinating and need to have a catheter inserted, which is what we usually call urinary retention, especially those who have urinary retention for more than two times, need to undergo surgery. In addition, some patients with prostate enlargement may have recurrent hematuria, recurrent urinary tract infections or even stones in the bladder, large diverticula in the bladder, hydronephrosis, and renal insufficiency should also be actively treated surgically. Some patients have to urinate hard for a long time due to prostate enlargement, and over time, inguinal hernia will occur, and these patients need to consider surgical treatment. Open surgery for prostatic hyperplasia is now rarely used. The most commonly used suprapubic transcatheter prostatectomy has a history of nearly 100 years, but although this procedure can completely remove the enlarged prostate, it is very traumatic for the patient, requires a lot of bleeding from the glandular fossa and even blood transfusion, and requires a long postoperative recovery time with prolonged bladder irrigation and indwelling catheterization for more than 1 week. The sphincter muscle may cause more postoperative complications such as urinary incontinence and urethral stricture. Therefore, most hospitals do not perform open surgery for prostatic hyperplasia, but open surgery may be more appropriate for patients with bladder disease (such as bladder diverticula, large stones in the bladder), knee ankylosis (unable to place the required position for intravesical surgery) or urethral strictures that cannot be operated on via the urethra. Open surgery is still indispensable as an alternate surgical approach. Transurethral resection of the prostate (TURP) is still the most classic and commonly used minimally invasive endoluminal procedure for the treatment of prostatic hyperplasia, and KLS for prostatic hyperplasia is a modified upgrade of TURP. With the continuous development of medical equipment, there are many surgical methods such as laser, plasma and other intracavitary treatment of prostate enlargement in the 21st century. The actual use of the Holmium laser, Thulium laser, Green laser and so on, but in practice, it is found that the working principle and characteristics of the laser itself can not completely remove the enlarged tissue for the larger prostate. Some prostate removal techniques, whether laser or plasma, have long learning curves for the surgeon, long operating times, and require more equipment (such as tissue crushers). Over the decades, the development of medical device imaging systems, advances in training methods, and proficiency in operating techniques have led to the relatively rapid development of a classic procedure such as TURP. This method is not visible on the patient’s body after surgery, with little surgical trauma and little intraoperative bleeding generally without blood transfusion; the operation time is short, and the operation procedure of cutting and suturing multiple layers of tissues is omitted, saving time; the patient recovers quickly after the operation, and can get out of bed 24 hours after the operation, and can be discharged from the hospital after 2-3 days by removing the catheter; and the electrodesis can be repeated, and for those who have recurrence of symptoms after the operation, the electrodesis can still be performed again to release In addition, various other causes of bladder neck obstruction can also be solved by transurethral electrodesiccation. The procedure can be repeated to relieve the obstruction; in addition, other causes of bladder neck obstruction can also be solved by transurethral resection, but clinical practice over the years has revealed some problems with TURP.
