Why is it important to talk about transperineal fusion prostate biopsy today?
Prostate cancer is the most common tumor in men. It is estimated to affect approximately 1 in 9 men throughout their lives and, in many cases, does not produce symptoms in the early stages. That is why it is so important to have accurate and early diagnostic methods.
Transperineal fusion prostate biopsy has become one of the most advanced techniques available in Europe today for safely and reliably confirming or ruling out prostate cancer. It allows for better localization of suspicious lesions, targeted sampling, and reduced risks associated with traditional biopsies.

What is a transperineal fusion prostate biopsy?
Transperineal fusion prostate biopsy is a diagnostic technique that combines two types of imaging:
- A multiparametric magnetic resonance imaging (MRI) scan of the prostate, performed previously.
- A real-time transperineal ultrasound.
Using an image fusion system, both tests are integrated to create a three-dimensional (3D) reconstruction of the prostate. Using this 3D image, the urologist can identify suspicious areas with great precision and direct the needle exactly to the points where a clinically significant tumor is most likely to be found.
In addition, micro-ultrasound technology is used, which provides superior resolution compared to conventional ultrasound. This facilitates the detection of small or clinically relevant lesions, increasing the overall reliability of the biopsy.

How is it done step by step?
The biopsy is performed transperineally, accessing the prostate through the skin of the perineum (the area between the scrotum and the anus), without passing through the rectum. This avoids contact with the intestinal flora and reduces the risk of infection.
The usual procedure includes:
- Sedation and positioning of the patient: the patient is sedated, comfortable, and pain-free.
- Live ultrasound: An ultrasound is performed while the patient is sedated.
- Merging ultrasound with previous magnetic resonance imaging: the system integrates both images.
- 3D reconstruction of the organ: a three-dimensional model of the prostate is generated.
- Obtaining samples: biopsy cylinders are taken with millimeter precision from the suspicious areas.
The total duration of a transperineal fusion prostate biopsy is usually 20 to 40 minutes, depending on the complexity of each case and the number of samples required, in accordance with standard times in advanced clinical practice.
Patient preparation and recovery
Preparation for a transperineal fusion prostate biopsy is usually minimal. In general, the following is recommended:
- Fasting for a few hours before the procedure, due to sedation.
- Adjustment of anticoagulant medication when appropriate, always under medical supervision.
- Occasionally, antibiotic prophylaxis according to individual clinical criteria.
After the test, the patient can resume normal activities within a short period of time, avoiding strenuous activity for a few days. It is normal to experience mild discomfort in the perineal area or small amounts of blood in the urine or semen, which are usually temporary.
Advantages of transperineal fusion prostate biopsy compared to conventional biopsy
Transperineal fusion prostate biopsy offers significant advantages over traditional transrectal biopsy:
- Greater diagnostic accuracy: detection capability is close to 95%, compared to around 30% for other techniques.
- Complete prostate examination: allows areas that are difficult to access with other techniques, such as the anterior zone, to be examined.
- Lower risk of infection: since it does not pass through the rectum, the possibility of prostatitis, urinary tract infections, or sepsis is reduced.
- Painless procedure: performed under sedation, providing a comfortable experience.
- Greater safety and rapid recovery: fewer complications and a quick return to daily life.
- 3D image fusion: the urologist directs the samples to the areas that are truly suspicious, avoiding "blind" biopsies.
- Fewer punctures: by focusing on areas of interest, fewer cylinders may be required to reach a diagnosis.
In summary, this technique significantly increases the probability of detecting significant tumors while reducing risks and discomfort for the patient.
In which cases is transperineal fusion prostate biopsy indicated?
Transperineal fusion prostate biopsy is a diagnostic tool, not a general screening test for healthy populations. It is particularly indicated when prostate cancer is suspected, for example in:
- Elevated or rising PSA (prostate-specific antigen).
- Abnormal findings on digital rectal examination, such as irregular prostate, presence of nodules, or hardening.
- Suspicious lesions on multiparametric prostate magnetic resonance imaging.
- Need to expand or confirm previous studies when other tests have been inconclusive.
It is not used as a preventive technique in men without symptoms or risk factors, but it does play a key role in patients who have already shown warning signs or abnormalities in initial tests.
Risks and common side effects
Like any medical procedure, transperineal fusion prostate biopsy is not entirely risk-free. However, the transperineal approach has been shown to have a lower complication rate than transrectal biopsy.
By not passing through the rectum, the likelihood of the following is significantly reduced:
- Prostatitis.
- Urinary tract infections.
- Sepsis (severe generalized infection).
The most common side effects following transperineal fusion prostate biopsy include:
- Discomfort or mild pain in the perineal area.
- Presence of blood in urine or semen for a few days.
These symptoms are usually mild and self-limiting. After the procedure, the patient receives clear instructions on when to contact the medical team if they have any concerns.

Frequently asked questions about transperineal fusion prostate biopsy
1. Is transperineal fusion prostate biopsy used only to diagnose cancer?
Its main use is to confirm or rule out prostate cancer, as it is currently the most accurate technique available. Although it can be used to study other lesions detected in imaging tests, its most common indication is related to suspected prostate cancer.
What exactly does this technique involve?
It combines images from a previous multiparametric MRI scan with real-time transperineal ultrasound. These are merged using advanced software to create a 3D model of the prostate, allowing the needle to be guided with high precision to the suspicious areas.
How is the biopsy performed? Is it painful?
It is performed transperineally, with the patient under sedation, so it is painless.
The procedure includes:
-
Sedation and positioning of the patient
-
Live ultrasound
-
Ultrasound + MRI fusion
-
3D reconstruction
-
Guided sampling
The process takes between 20 and 40 minutes, depending on each case.
Does it require special preparation?
Preparation is minimal. The following is usually recommended:
-
Fasting prior to sedation
-
Adjustment of anticoagulant medication if necessary
-
Occasionally, antibiotic prophylaxis
Most patients resume normal activities within 24 hours.
What are the advantages over a traditional prostate biopsy?
It offers significantly greater benefits:
-
Greater accuracy (up to 95% detection rate)
-
Possibility of biopsying difficult areas, such as the anterior area
-
Lower risk of infection
-
Painless procedure with sedation
-
Faster recovery
-
Fewer cylinders needed thanks to 3D precision
Does it detect more cancer than traditional biopsy?
Yes. Conventional biopsy detects approximately 30% of suspected cancers, while transperineal fusion biopsy detects around 95%, tripling the diagnostic capacity.
