What is USG SCROTUM WITH DOPPLER?
Ultrasound imaging of the scrotum uses sound waves to produce pictures of a male's testicles and surrounding tissues. It is the primary method used to help evaluate disorders of the testicles, epididymis (tubes immediately next to the testicles that collect sperm), and scrotum. Ultrasound is safe, non-invasive, and does not use ionizing radiation.
This procedure requires little to no special preparation. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.
What is Ultrasound Imaging of the Scrotum?
Ultrasound imaging of the scrotum provides pictures of a male's testicles and the surrounding tissues.
Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. It is safe and painless. It produces pictures of the inside of the body using sound waves. Ultrasound imaging is also called sonography. It uses a small probe called a transducer and gel placed directly on the skin. High-frequency sound waves travel from the probe through the gel into the body. The probe collects the sounds that bounce back. A computer uses those sound waves to create an image. Ultrasound exams do not use radiation (x-rays). Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs. The images can also show blood flowing through blood vessels.
What are some common uses of the procedure?
Ultrasound imaging of the scrotum is the primary imaging method used to evaluate disorders of the testicles, epididymis (tubes immediately next to the testicles that collect sperm made by the testicle), and scrotum.
This study is typically used to:
- determine whether a mass in the scrotum felt by the patient or doctor is cystic or solid and its location.
- diagnose results of trauma to the scrotal area.
- diagnose causes of testicular pain or swelling such as inflammation or torsion.
- evaluate the cause of infertility such as varicocele.
- look for the location of undescended testis.
Sudden onset of pain in the scrotum should be taken very seriously. A common cause of scrotal pain is epididymitis, an inflammation of the epididymis. It is treatable with antibiotics. If left untreated, this condition can lead to an abscess or loss of blood flow to the testicles.
Ultrasound can often detect an absent or undescended testicle as well. It is estimated that approximately three percent of full-term baby boys have an undescended testicle. The testicle normally migrates from the abdomen down a short passage called the inguinal canal and then into the usual position in the scrotal sac before birth. If not present in the scrotal sac, the testicle may have stopped in the inguinal region, in which case the ultrasound examination will often see it. If the testicle has not left the abdominal cavity, it may not be seen by sonography. If a testicle is not detected, a urologist may be consulted in order to decide whether additional imaging such as an MRI is needed to determine its location. If the testicle is found to be in the inguinal region, it may be moved into the scrotum. If left in the abdomen too long, the testicle may become cancerous and may need to be removed.
Ultrasound can identify testicular torsion, the twisting of the spermatic cord that contains the vessels that supply blood to the testicle. Testicular torsion is caused by abnormally loose attachments of tissues that are formed during fetal development. Torsion commonly appears during adolescence, and less often in the neonatal period, and is very painful. Torsion requires immediate surgery to avoid permanent damage to the testicle.
Ultrasound also can be used to locate and evaluate masses (lumps or tumors) in the testicle or elsewhere in the scrotum. Collections of fluid and abnormalities of the blood vessels may appear as masses and can be assessed by ultrasound. Masses both outside and within the testicles may be benign or malignant and should be evaluated as soon as they are detected.
