The actual fact is that you can find a cyst in the prostate gland when you have an ultrasound examination of the suspected prostatitis. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. (1) True prostate cyst: the prostate gland is obstructed during embryonic development, causing the prostate duct to narrow, resulting in obstruction and gradual retention of the contents and formation, so it belongs to the retention prostate cyst. (2) Congenital cysts: The cysts are formed when the middle renal duct and the middle paranephric duct develop abnormally and the lumen of the duct is partially dilated. The cysts that originate from the paramedian duct are often located in the middle of the posterior prostate, while the cysts that originate from the mesonephric duct are located on the sides. These cysts do not actually originate in the prostate gland and often adhere to the posterior bladder wall. The size of the cyst can often grow to be so large that it compresses the bladder neck causing difficulty in urination; compression of the rectum causes a feeling of anal swelling and difficulty in defecation. Congenital prostate cysts are often associated with congenital disorders such as hypospadias, cryptorchidism, and renal insufficiency. (3) Acquired cysts: These are caused by incomplete or intermittent obstruction of the vesicles by the tough prostate stroma, which gradually thickens the epithelium of the vesicles and eventually results in retention cysts, which can be located anywhere in the prostate or protrude into the bladder neck and are 1-2 cm in diameter. (4) Inflammatory cysts: These are caused by chronic inflammation of the prostate that leads to the proliferation of connective tissue, resulting in narrowing of the prostate ducts. (4) Inflammatory cysts: This is a chronic inflammation of the prostate that causes the connective tissue to proliferate, leading to narrowing of the prostate ducts and retention of secretions to form cysts. (5) Parasitic cysts: caused by parasites, such as worms that can cause chronic inflammation in and around the prostate ducts, or by granulomatous proliferation, gradually forming cysts. The various cysts mentioned above are most common with retention prostate cysts, which can occur in any part of the gland. 2, pathological changes of prostate cysts Cysts are seen by pathological section, the cysts consist of normal glandular vesicles or are multi-housed, the vesicles are lined with columnar epithelium, some are low cubic epithelium, the cysts are filled with plasma or plasma blood fluid. The prostate cysts can be complicated by infection and stones, and the larger cysts can obstruct the urine flow when they grow and press against the urethra or bladder neck. Common symptoms include urinary urgency, frequent urination, straining to urinate, thin urine line, difficulty in urination and urinary retention; when pressed into the rectum, it can cause difficulty in defecation. If the cyst is large, the cyst is palpable in the prostate on rectal examination, and the urographic image shows an arc-shaped pressure mark in the posterior urethra, and ultrasound and CT can clarify its location. 4, the treatment of prostate cysts smaller and asymptomatic cysts, generally as long as no secondary infection, etc., can not be treated, but only to pay attention to dynamic observation of its changes. The actual cysts or small cysts that have symptoms can be treated surgically. There are reports of cyst puncture and aspiration via perineum or rectum under ultrasound positioning, followed by injection of coagulant, but because of incomplete or intermittent obstruction of the glandular vesicles, even after the above puncture and aspiration, the cyst is still prone to recurrence due to local glandular secretion.
