Right!

Scrotal ultrasound, a male scrotum detection technique, is often used for urology-related diseases.

There are two general methods of scrotal ultrasound scanning:

(1) Longitudinal scan: Take a left-handed food and thumb to properly fix the testis to perform a longitudinal multi-plane scan to show

(1) Ultrasound can help find small testicular tumors, including local recessive cancers that have retroperitoneal metastasis (reported by literature only 2 ~ 3mm); Ultrasound can also help to examine patients with testicular tumors for retroperitoneal and hilar lymph nodes Metastases to facilitate clinical staging. Color Doppler ultrasound can improve the ultrasound detection rate or sensitivity of testicular tumors, but it lacks specificity to distinguish it from certain inflammations.

(2) In the case of scrotal trauma, ultrasound examination helps to correctly judge the scrotal hematoma and determine whether the testis is damaged; it helps to determine the indications for surgical exploration, such as testicular rupture and foreign body retention.

(3) Ultrasound diagnosis of varicocele is sensitive and accurate. The total CDI sensitivity can be as high as 100%.

(4) The method of ultrasound diagnosis of cryptorchidism is simple, accurate, non-radioactive and non-traumatic, so it is the preferred method. Ultrasound sensitivity is slightly worse than X-ray and CT. Ultrasound examination of the latter is often difficult. If ultrasound does not detect cryptorchidism, "absent testis" must not be diagnosed. CT or surgical exploration is still necessary.

Be applicable:

(1) Swollen scrotum of unknown cause.

(2) Diagnosis and identification of testicular, epididymal and penile masses.

(3) Diagnosis of scrotal and testicular trauma, testicular torsion, and penile trauma.

(4) Varicocele.

(5) cryptorchidism.
