Benign prostatic hyperplasia, commonly known as prostate enlargement and prostate hypertrophy, is one of the most common diseases in older men. The main symptoms are gradually increasing difficulty in urination, thinning of the urine line, waiting for urine, weakness of the urine line, frequent urination, increased nocturia (sometimes up to 8-10 times/night), distension and discomfort in the bladder area, occasionally accompanied by hematuria of the naked eye or microscopic hematuria, which can seriously affect life and even deter from going out for activities. In severe cases, it can also lead to some related complications, such as hydronephrosis and hernia. The most fundamental reason for these symptoms is that the enlarged prostate gland obstructs the discharge of urine flow. Treatment options vary depending on the degree of obstruction, but the underlying goal is the same: to reduce or remove the obstruction to urinary flow by the enlarged prostate gland. For patients with less pronounced symptoms, observation is advocated. For patients with slightly more severe symptoms, oral medication can be considered first and supplemented with minimally invasive treatment, such as high energy focused ultrasound painless and non-invasive green minimally invasive treatment means, etc. As the condition progresses and seriously affects the patient’s life, surgical treatment can be adopted. The most commonly used is transurethral resection of the prostate, which is not very traumatic and has a quicker recovery after surgery, and of course there are more minimally invasive ways, such as high energy focused ultrasound performed outside the body, which is not open, painless and has no obvious complications, and has received significant attention in recent years and is increasingly accepted by the majority of patients. There are also some minimally invasive modalities that are constantly being explored.
