Name of the Procedure:

Biopsy of Testis, Needle (Fine Needle Aspiration, Testicular Fine Needle Biopsy)

Summary

A needle biopsy of the testis involves using a thin needle to extract small samples of tissue from the testicles. This minimally invasive procedure allows for the examination of testicular tissue to diagnose underlying problems.

Purpose

This procedure is used to diagnose the cause of male infertility, detect testicular cancer, and investigate other testicular abnormalities. The goal is to obtain a tissue sample to identify the presence of disease or abnormal conditions within the testicle.

Indications

• Unexplained infertility
• Presence of a testicular mass or lump
• Abnormal results from other testicular examinations or tests
• Persistent pain or discomfort in the testicle
• Hormonal abnormalities

Preparation

• Patients may need to fast for a few hours before the procedure.
• Medications, especially blood thinners, may need to be adjusted or temporarily stopped.
• A physical examination and possibly an ultrasound of the testicles will be performed beforehand.

Procedure Description

1. Anesthesia: Local anesthesia is administered to numb the scrotal area.
2. Localization: The testicle is carefully located, often using ultrasound guidance.
3. Biopsy: A thin needle is inserted into the testicle through the scrotal skin to collect tissue samples.
4. Collection: Multiple samples may be taken to ensure adequate tissue is obtained.
5. Completion: The needle is removed, and slight pressure is applied to minimize bleeding.

Tools Used:

• Fine needle
• Ultrasound machine (for guidance)
• Local anesthetic

Duration

The procedure typically takes about 15 to 30 minutes.

Setting

This procedure is usually performed in an outpatient clinic or a hospital setting.

Personnel

• Urologist or Interventional Radiologist (performs the procedure)
• Nurse or Medical Assistant (provides assistance and care)
• Anesthesiologist (if deeper sedation is required)

Risks and Complications

• Minor bleeding or hematoma formation
• Infection at the biopsy site
• Pain or discomfort during and after the procedure
• Rarely, damage to the testicle or surrounding structures

Benefits

• Accurate diagnosis of testicular conditions
• Helps guide appropriate treatment plans
• Minimally invasive with a relatively quick recovery period

Recovery

• Patients may experience mild discomfort and swelling, typically managed with over-the-counter pain medication.
• Avoid strenuous activities and sexual activity for a few days.
• Keep the area clean and dry, following specific instructions from the healthcare provider.
• Follow-up appointments to discuss results and further steps.

Alternatives

• Open surgical biopsy: more invasive but might be necessary if needle biopsy is inconclusive.
• Observation and non-invasive imaging: used if the condition is not immediately life-threatening or if the patient has contraindications for biopsy.

Pros and Cons:

• Needle Biopsy: Less invasive, quicker recovery, but may not always yield sufficient tissue.
• Surgical Biopsy: More comprehensive tissue sampling, but involves a longer recovery and higher risk of complications.

Patient Experience

• During the procedure, patients might feel a prick or pressure from the needle.
• Post-procedure, expect some mild discomfort, similar to a bruise, which should subside in a few days.
• Pain management may include over-the-counter pain relievers and supportive underwear to minimize discomfort.
