Prostate enlargement is one of the common diseases that plague the health of elderly men and has a serious impact on the daily life of patients, so here is a brief introduction to the overview of the disease, its hazards and the current status of treatment. The performance of prostatic hyperplasia depends on the degree of obstruction, the rate of progression of the lesion and the presence of complications. The main symptoms include the following: ① frequent urination: the most common early symptoms, especially the increase in the number of nocturnal urination is more obvious. The occurrence of 1 to 2 nocturnal urination in the elderly who originally did not get up at night often reflects the arrival of early obstruction, while the development from 2 times per night to 4~5 times per night or even more indicates the development and aggravation of the lesion. (ii) Difficulty in urination, including waiting before urination, feeling of effort during urination, thinning of the urine line, and incomplete dripping after urination. ③ urinary retention and incontinence: when the obstruction reaches a certain degree, urinary retention gradually occurs and urinary incontinence appears, with urine flowing out from time to time without the patient himself feeling it. There are also patients who suffer from acute urinary retention due to inability to discharge urine due to cold, alcohol consumption, sedentary and constipation. It is also the reason why some patients come to the clinic. The symptoms associated with complications: when prostate enlargement is combined with infection or stones, there can be a sudden increase in the number of nocturnal urination, urinary urgency, painful urination, hematuria and fever; prolonged obstruction due to enlargement can be combined with hydronephrosis and changes in kidney function, when there can be loss of appetite, nausea, vomiting, anemia, etc. The actual fact is that you can find a lot of people who are not able to get a good deal on this. The purpose of medication is to delay the progression of the disease and improve the symptoms of the lower urinary tract. Currently, most of the alpha-blockers (doxazosin, tamsulosin, etc.) and 5 alpha reductase inhibitors (finasteride) are used in combination, and Chinese medicines also have a role in improving symptoms. Those with severe obstruction, high residual urine volume, and obvious symptoms and poor results of medication should consider timely surgery. The actual surgery to remove the enlarged prostate tissue is also the fundamental method to cure the prostate enlargement. With the continuous advancement of modern minimally invasive technology, minimally invasive surgical removal of the prostate has become the most important means of treating this disease. The newest minimally invasive surgical treatment for prostate enlargement is transurethral resection of the prostate (TURP), which has emerged in the last 20 years. The procedure involves simply inserting the electrodes through the urethra and cutting straight into the prostate area. The procedure has the advantages of less trauma, less bleeding, shorter operation time and faster patient recovery, and is still the mainstream method of treating the disease. The 3rd generation of minimally invasive electrodes (bipolar plasma electrodes), which began in 2000, has its own merits. During the operation, the use of saline as a medium can avoid the occurrence of electrodesiccation syndrome, which greatly improves the safety of the operation. At the same time, the technology has both cutting and hemostasis functions, and there is a coagulation feeling when cutting to the pericardium, which can reduce the chance of pericardial cut. The bipolar circuit cutting has good hemostasis effect, and the low temperature operation can reduce the degree of thermal injury, avoid the closed-hole reflex and reduce the occurrence of erectile nerve injury. With less intraoperative bleeding and shorter recovery time for patients after surgery, it has its outstanding advantages in the treatment of prostate enlargement. It also makes electrodesurgery of the prostate increasingly safe and mature, bringing light to the treatment of the majority of patients.
