Procedure of testicular biopsy

Testicular puncture biopsy is a clinical technique with both diagnostic and therapeutic effects. Usually, if there is a disease in male sperm, this technique is often used for examination. Many people may not know much about this operation, so what are the surgical steps of testicular puncture biopsy? Next, let us learn about this aspect through this article.

Preparation for testicular biopsy

Before testicular biopsy, the centrifuged semen should first be examined under a microscope to see if there are sperms. If the amount of semen is less than normal, urine should be taken after ejaculation to rule out retrograde ejaculation. The fructose in the semen can be measured to see if there are seminal vesicles and whether the vas deferens is blocked. In addition, the vas deferens and epididymis should be palpated. If they are absent on both sides, it is a good explanation for azoospermia. For patients with moderate or severe oligospermia, accompanied by small testicles and significantly increased FSH, testicular biopsy is not necessary.

Testicular biopsy procedure steps:

⒈ Routine skin preparation and disinfection of the surgical area.

⒉Fix the testicles.

The doctor should select one testicle according to the need and use the left middle finger, ring finger and thumb to fix the testicle firmly. The epididymis end of the testicle should be on the palm of the hand.

Hold the testicle under examination with your hand, tighten the scrotal skin on the surface,

⒊ Local anesthesia.

Select a relatively avascular area and apply local anesthesia.

⒋ Surgery.

After successful anesthesia, a special testicular biopsy tool is used to quickly remove the seminiferous ducts in the testicle in steps, and then the specimen is placed in a fixative to apply pressure to the surgical site to stop bleeding. The amount of bleeding is very small, or even no bleeding. No sutures are required, and bandages are required after the operation.

⒌Postoperative treatment.

Oral anti-inflammatory drugs were used for 3 days, and the tape was removed after 3 days. No incision was left after the operation. No obvious sequelae were found.

⒍Specimen observation.

Our professional doctors will personally review the films and analyze them based on the patient's condition.

The surgical process of testicular puncture biopsy is as described above. Generally speaking, this operation is relatively minor, so patients should not be overly nervous before undergoing this operation and should learn to relax. After all, current medical technology is relatively advanced. No matter what disease they suffer from, patients should not put too much pressure on themselves and should not be too nervous.
