Yesterday, I went to Longkou to have a prostate electrosurgery. After the surgery, one of their doctors asked me what is the appropriate level of gland removal when it comes to the prostate, and I thought about it, and this is really a good question, because there are various considerations to answer this question. First of all, what is the purpose of doing prostate electrosurgery and what is our or the patient’s main concern? It should be said that the purpose of prostate electrosurgery is to relieve the difficulty in urination, not to remove the prostate, and the patient’s main concern is not whether the prostate is completely removed, but whether the problem of difficulty in urination is solved. In addition, the patient’s physical condition must be taken into account, whether or not they have enough tolerance to withstand the shock of complete removal of the prostate. There is also the proficiency of the operator. The main reason is because of the enlargement of the prostate gland, which presses on the urethra and obstructs the flow of urine when the patient urinates. The purpose of surgery is to ensure the safety of the patient and to relieve this pressure effect, which is to effectively remove the prostate tissue that presses on the urethra and make the patient’s urination flow smoothly. In patients with severe prostate enlargement, when entering the cystoscope, they will feel that the mirror is obviously compressed by the prostate tissue and that the mirror is restricted in its movement, and when the prostate tissue is effectively removed, they will feel that the mirror is moving freely. Before the surgery begins, after entering the mirror you can find that most prostate enlargement is obviously bilateral prostate tissue, as long as the surgery effectively removes this bilateral gland, you can achieve the purpose of unobstructed urination. The other thing is to make the cut surface smooth in order to make the surgery perfect. During the surgery, throughout the entire procedure is the control of bleeding, control of the operation time and control of the absorption of the flushing fluid. The process of surgery is the effective removal of prostate tissue and tight hemostasis. The prostate enlargement patients are elderly patients who are poorly tolerant of surgical blows such as bleeding and absorption of flushing fluid. The surgeon should always pay attention to the changes in the patient during surgery, control the amount of bleeding during surgery and absorption of flushing fluid, and terminate the surgery at any time if necessary. The surgical procedure should preferably be carried out in image limits, steadily, with complete hemostasis for one image limit after the resection is completed, and then the resection of the other image limit should be carried out. This prevents the resection from being too extensive and incomplete hemostasis, which eventually results in a situation where the bleeding surface is large and finding the bleeding point is difficult. In the process of resection, for the neck of the bladder, when the circumferential fibers are seen, it is the extent of the resection, to the envelope. Because the prostate is a spherical tissue, it is important to dig deeper during the excision process to remove the central prostate tissue as appropriate.
