Learn more about transperineal prostate biopsy in Mexico

Transperineal prostate biopsy is an advanced technique that allows prostate samples to be obtained with greater precision and a lower risk of infection. In Mexico, this modality is gaining popularity due to its effectiveness in detecting prostate cancer in the early stages. The main advantage of transperineal biopsy is that it improves the location of the tumor and reduces complications compared to traditional methods.

This procedure uses ultrasound and magnetic resonance imaging to guide the needle through the perineum, helping to obtain more specific samples from the suspicious area. In addition, it is an accessible option in specialized clinics in Mexico, where urology experts combine technology and experience to provide a reliable diagnosis.

With a generally rapid recovery and low associated risks, transperineal biopsy is presented as a safe and effective alternative for those who need an accurate diagnosis of prostate cancer. Its implementation in Mexico reflects the constant quest to improve medical care and patient outcomes.

Key Points

• Transperineal biopsy improves the accuracy of prostate diagnosis.
• The procedure uses advanced imaging to guide the sample.
• In Mexico, it's a safe option available in specialized centers.

Transperineal prostate biopsy in Mexico

Transperineal prostate biopsy is a precise method for obtaining prostate samples and detecting cancer. This procedure is performed with advanced technology to improve the safety and accuracy of the diagnosis.

Definition of the procedure

A transperineal prostate biopsy involves removing samples of prostate tissue through the skin of the perineum, located between the scrotum and the anus. A thin, image-guided needle, such as magnetic resonance fused with ultrasound, is used to improve accuracy.

This method avoids the rectal route, thus reducing the risk of infections that may occur with the transrectal biopsy. The procedure is performed under local anesthesia or sedation, to ensure that the patient does not feel pain. The samples obtained are then tested for the presence of cancer cells.

Advantages over other methods

Transperineal biopsy has significant benefits over traditional transrectal biopsy:

• Lower risk of infection because it does not cross the rectal mucosa.
• Better access to deep areas of the prostate, especially the former area.
• Increased accuracy when combined with magnetic resonance imaging.
• The procedure is generally well tolerated and safe.

These advantages make it a preferred option in specialized centers. In addition, the application of advanced technology such as image fusion makes it possible to detect small or difficult to access tumors.

Medical indications

This type of biopsy is primarily indicated in cases of:

• Elevated or increasing levels of prostatic specific antigen (PSA).
• Suspicious results in rectal examination.
• Patients who have had previous negative biopsies, but with persistent clinical suspicion.
• Need for accurate diagnosis to plan cancer treatment.

It is especially recommended in patients at high risk of infection or when difficult prostate areas need to be evaluated with traditional methods. The urologist decides the procedure based on the patient's history and symptoms, as well as on previous studies.

Process and clinical considerations

The procedure requires specific preparation, a careful method during sample collection, and appropriate care afterwards to avoid complications. Each step seeks to maximize accuracy and minimize risks.

Preparation before the biopsy

Before the biopsy, the patient must report allergies and medications, especially anticoagulants, which may increase the risk of bleeding. It is common to stop these drugs several days early.

Proper cleaning of the perineal area is recommended to reduce infections. In some cases, a preventive antibiotic is administered, although the transperineal route has a lower risk of infection than the transrectal route.

The patient is usually given local anesthesia to avoid pain, staying awake but comfortable. You may also need to fast for a few hours beforehand, depending on medical indications and the type of anaesthesia being used.

Procedure steps

A transperineal biopsy is done by inserting a needle through the skin of the perineum to reach the prostate. The doctor uses ultrasound images to guide the needle precisely.

Several tissue samples are removed, especially from areas that are difficult to reach with the transrectal route. These samples help determine the presence and severity of the cancer.

The procedure takes 15 to 30 minutes. During the biopsy, the patient is monitored for any discomfort or unexpected reaction.

Post-operative care

After the biopsy, it's normal to feel mild discomfort in the perineum area, which usually goes away in a few days. Your doctor may recommend pain relievers.

It's important to avoid strenuous physical activity and sexual intercourse for at least a week to reduce the risk of bleeding or infection.

The patient should report any signs of infection, high fever, or persistent bleeding. Recovery is usually quick and the risk of complications is low compared to other techniques.

Results, risks and availability

Transperineal prostate biopsy provides reliable results for the diagnosis of cancer. However, like any medical procedure, it can pose specific risks. In addition, this technique is available in several specialized clinics and hospitals in Mexico, which have the necessary technology to carry it out.

Interpretation of results

The transperineal biopsy results are usually ready 5 to 7 days after the procedure. The report details whether cancer cells are detected and how aggressive they are, helping to plan appropriate treatment.

Physicians explain the results to the patient and can provide a copy for personal consultation. The accuracy of this biopsy is high, as it takes samples directly from the suspicious area, reducing false negatives.

Possible risks and complications

Although transperineal biopsy reduces the risk of infection compared to transrectal biopsy, there are risks such as pain, bleeding and bruising in the perineal area.

The incidence of serious infections, such as sepsis, is low because the needle does not pass through the rectum, preventing bacteria from entering. However, the patient should inform their doctor if they have a fever, severe pain or prolonged bleeding after the procedure.

Frequently Asked Questions

What are the disadvantages of opting for a transperineal biopsy compared to other methods?

The transperineal biopsy is more invasive than the transrectal biopsy and may require local or general anesthesia. It also has a slightly longer recovery time. However, the risk of infection is lower compared to the transrectal route.

What is the most recent and most effective method for prostate biopsy?

Transperineal fusion biopsy combines ultrasound and magnetic resonance imaging to locate the tumor more precisely. This method makes it possible to obtain more specific samples of the suspected tissue and to improve the diagnosis.

What preparation does a patient require before undergoing a transperineal biopsy?

Generally, the patient should avoid certain medications that affect coagulation and maintain adequate cleaning of the perineal area. In some cases, preventive antibiotics are given and fasting is indicated prior to the procedure.

What are the potential risks and side effects of a transperineal prostate biopsy?

Risks include minor bleeding, infection, and discomfort in the perineal area. Some patients may experience swelling or difficulty urinating, but these effects are usually temporary and manageable with medical treatment.
