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. Epididymal stones examination items are as follows: 1, 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 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. 2.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 of great value in the diagnosis, differential diagnosis and judgment of treatment effect of inferior vena cava obstructive disease. 3.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.
