Prostatic hyperplasia, also known as benign prostatic hypertrophy, is a common benign condition in older men. The incidence gradually increases with age. The cause of the disease is that the enlarged prostate squeezes the urethra, leading to a series of dysuria symptoms, such as urinary frequency, urinary urgency, weak urinary stream, incomplete urination, waiting for urine, urinary retention and other dysuria symptoms. These symptoms seriously affect the patient’s quality of life, and untimely treatment will lead to a series of complications, such as urinary tract infection, bladder stones, hydronephrosis and renal insufficiency. Therefore, active treatment is needed. Early stage can be treated by medication, but with the development of the disease, eventually most part of the patients need surgical treatment. Timing of surgery for prostatic hyperplasia: The treatment of prostatic hyperplasia is mainly based on medication in the early stage, such as POLYZONE, HALO and other drugs. With the progress of the disease, when there are complications such as urinary retention, recurrent hematuria, recurrent urinary tract infections, large amount of residual urine in the bladder, bladder stones, and secondary bilateral hydronephrosis, it is recommended that surgical treatment be used. Treatment of prostate enlargement: Surgical treatment of prostate enlargement includes open surgery, transurethral prostatectomy and laser surgery. With the further development of science and technology, traditional open surgery is becoming less and less common, and transurethral laser gasification surgery is gradually replacing most of the transurethral electrocautery of the prostate with its advantages of less bleeding and fewer complications. Principle and advantages of laser: 2 micron laser principle: 2 micron laser surgical system, is a revolutionary advancement in laser minimally invasive surgical technology, when the 2 micron laser irradiates the tissue, the powerful energy is instantly absorbed by the water, which produces a strong effect, so as to achieve the purpose of rapid and accurate vaporization and cutting and removal of the tissue. 2 micron laser penetration depth in the tissue is only 0.3 mm, and the removal of the tissue left after the The coagulation layer is 1 millimeter, the wound surface is smooth, and the safety performance is high.2 micron laser is applied to the treatment of prostate hyperplasia and other urological diseases, and has achieved great success. Compared with previous prostate surgery methods. Advantages of 2 micron laser: adopting a new operation mode, local vaporization combined with cutting, rapid and effective removal of hyperplastic tissues, short operation time, excellent hemostatic performance, intraoperative and postoperative bleeding, clear surgical field, high safety, postoperative urinary incontinence, urethral stenosis and other complications, postoperative urethral catheterization time and hospitalization time is short, wide range of indications for the operation, elderly, high-risk or macroglandular patients are still possible to carry out endoscopic treatment In addition, 2-micron laser can also be used in the treatment of bladder tumors, glandular cystitis, bladder neck contracture and urethral stenosis, which also has outstanding advantages compared with the traditional surgical methods. 2-micron laser technology for the treatment of urological diseases should be the first choice of course today. Self-care after prostate laser surgery: 1, to prevent cold, cold tends to aggravate the condition of prostate hyperplasia. Therefore, patients must pay attention to the cold, prevent cold and upper respiratory tract infection. 2, absolutely avoid alcohol, less spicy food, drinking alcohol can make the prostate and bladder neck congestion and edema and induce urinary retention. Spicy stimulating food, both can lead to sexual organs congestion, but also will make hemorrhoids, constipation symptoms worsen, oppression of the prostate, aggravate urination difficulties. 3, moderate drinking water, drinking too little water will not only cause dehydration, but also unfavorable urination on the flushing effect of the urinary tract, but also easy to lead to the concentration of urine and the formation of insoluble stones. Therefore, in addition to the appropriate reduction of water at night, so as not to overfill the bladder after sleep, should drink more water during the day. 4, careful use of drugs, some drugs can aggravate urinary difficulties, large doses can cause acute urinary retention, which are mainly atropine, belladonna tablets and ephedrine tablets, isopropyl adrenaline.
