Epididymal stones are also known medically as seminal vesicle stones, and stones that occur within the seminal vesicles are called seminal vesicle stones. It is extremely rare clinically. Due to chronic inflammation of the seminal vesicles, ejaculatory duct obstruction, seminal vesicle fluid retention, metabolic disorders, etc. caused by inorganic salt crystals deposited on the shedding of epithelial cells and inflammatory exudate formation. Stones are often multiple, generally small, 1-2 millimeters in size, the surface is smooth and hard brown. Seminal vesicle stones can occur singly or in multiples, and rarely show symptoms, occasionally see blood sperm, ejaculation pain or perineal discomfort. Seminal vesicle stones are rare, round, hard and smooth. Corriere reported that the composition of seminal vesicle stones is very similar to pancreatic stones, and the formation of pancreatic stones is related to the abnormal expression of the gene that secretes pancreatic stone proteins, thus it is believed that the cause of seminal vesicle stone formation is due to the lack of proteases in semen. The examination items of epididymal stones are as follows: 1. Common signs There may also be pain in the groin, which may radiate to the testicles and perineum. The stone stays in the ejaculatory duct, in the obstruction of semen discharge, can cause colic. Symptoms are aggravated when the penis is erected or when ejaculation occurs. There may be bloody semen. 2.Rectal palpation Inspection of the outer upper edge of the prostate gland can be touched more than one hard texture, smooth surface of the stone feeling or stone friction. The seminal vesicles become hard and have pressure pain. 3, X-ray film can be found in the seminal vesicles have stone shadow. Tiger red plate agglutination test Tiger red plate agglutination test is used to diagnose brucellosis. Brucellosis is a zoonotic, acute and chronic infectious disease caused by the bacterium Borrelia burgdorferi. Infection is caused by contact with diseased animals or consumption of infected milk or milk products. Incubation period of 1 to 3 weeks, clinical features are slow onset, prolonged fever, sweating, weakness, generalized pain and arthralgia, acute symptoms mostly subside in 3 to 6 months. 5.Abdominal vascular ultrasonography Abdominal vascular ultrasonography for abdominal aortic aneurysm can measure anterior and posterior diameters, long and wide diameters of the aneurysm, which can be used as the preferred method for entrapment of abdominal aortic aneurysm. Abdominal ultrasound is valuable for the diagnosis and differential diagnosis of inferior vena cava obstructive disease and the judgment of treatment effect. 6.Laparoscopy A method of examination and treatment of abdominal cavity through laparoscope. Laparoscopy can clearly observe the pelvic tissue structure and the appearance of ovarian tumors, which is of great significance to the diagnosis and treatment of ovarian diseases. It is especially important to determine the nature of the tumor when deciding what kind of surgery to perform on the ovaries, such as tumor removal, oophorectomy, or preservation of the ovaries.
