Scrotal Ultrasound

There are two types of scrotal ultrasound scanning methods: 1. Longitudinal scanning with left hand food and thumb to properly fix the testicle for longitudinal multi-planar scanning to show the ultrasound structure of the testicle, the epididymis head and part of the spermatic cord. 2, cross-scanning bilateral observation of the scrotal skin, testis and epididymis morphology, size, internal echo, observe the presence or absence of fluid and echo in the sheath around the testis. Basic Information Specialist classification: male examination inspection classification: ultrasound Applicable gender: whether the male is fasting: not fasting Tips: Expose the lower abdomen and genital area, use a treatment towel or paper towel to lift the scrotum to the anterior abdominal wall and hold the patient's hand. Normal value Scrotal normal sonogram An oval testis was seen in the scrotum and the capsule was smooth. The light spots in the testicles are moderately echoed and evenly distributed. The epididymis head is visible above the testicles, and the echo is similar to the testicles, mostly triangular. The epididymis and tail are located on the dorsal and inferior sides of the testis, and the echo is low and easy to be missed. Normal spermatic cord two-dimensional ultrasound is not easy to display, but CDFI can display the blood flow signals of the arteries and veins. Clinical significance 1. Ultrasound helps to detect small testicular tumors, including local recessive carcinoma with retroperitoneal metastasis (only 2 to 3 mm reported in the literature). Ultrasound also helps to check for post-peritoneal and renal hilar lymph node metastasis in patients with testicular tumors. Tumors to facilitate clinical staging. Color Doppler ultrasound can improve the ultrasound detection rate or sensitivity of testicular tumors, but the identification of certain inflammation is lack of specificity. 2, scrotal trauma, ultrasound examination helps to correctly determine the scrotal hematoma and determine whether the testicular damage, help determine the indications for surgical exploration, such as testicular rupture, foreign body retention. 3. Ultrasound diagnosis of varicocele is sensitive and accurate. The total sensitivity of CDI can be as high as 100%. 4. Ultrasonic diagnosis of cryptorchidism is simple, accurate, and non-radioactive and non-invasive, so it is the preferred method. Ultrasound sensitivity is slightly worse than X-ray and CT, and it is often difficult to perform ultrasonography on the peritoneum. If ultrasound fails to detect cryptorchidism, it is not necessary to diagnose "testicular deficiencies". CT or surgical exploration is still necessary. Be applicable: 1. Unexplained scrotal swelling. 2. Diagnosis and identification of testes, epididymis and penile masses. 3, scrotum, testicular trauma, testicular torsion, penile trauma diagnosis. 4, varicocele. 5, cryptorchidism. Precautions Usually take the supine position, expose the lower abdomen and genital area, use a treatment towel or paper towel to lift the scrotum to the anterior abdominal wall and hold the patient with your hand. Inspection process The standing position is used for the examination of varicocele and hernia. A couplant is added to the surface of the scrotum to ensure adequate contact between the skin and the probe. Not suitable for the crowd Generally there are no people who are not suitable. Adverse reactions and risks Generally no adverse reactions.
