Local Anaesthetic Transperineal Prostate Biopsy (LATP)

Local Anaesthetic Transperineal Prostate Biopsy (LATP) is a modern, patient-friendly diagnostic technique that has significantly reduced the risks associated with traditional prostate biopsy methods while maintaining high diagnostic precision.

What is an LATP Biopsy?

An LATP biopsy is a procedure used to collect tissue samples from the prostate to check for cancer cells. The defining feature of this method is the transperineal approach.

Traditionally, biopsies were performed “transrectally” (through the wall of the rectum). In an LATP biopsy, the needle is inserted through the perineum—the skin located between the scrotum and the anus. The main advantage of this is to assess areas of prostate difficult to reach via the transrectal route and also reduce risk of post-biopsy infection.

Why LATP is the New Standard in Prostate Safety

Urologists are increasingly moving away from transrectal biopsies in favor of the transperineal (LATP) route for several critical reasons:

• Near-Zero Infection Risk: Because the needle passes through sterilized skin rather than the rectum, the risk of serious infection (sepsis) is virtually eliminated.
• No Need for Strong Antibiotics: Due to the low infection risk, patients typically do not require the heavy doses of antibiotics needed for older biopsy methods.
• Superior Accuracy: The transperineal angle allows the urologist to reach all parts of the prostate more easily, including the “anterior zone” (the front of the gland), which is often difficult to access via the transrectal route.
• Local Anaesthetic Convenience: You get the benefits of a surgical-grade biopsy without the need for general anesthesia, allowing for a faster recovery and no hospital stay.

The Procedure: What to Expect

The LATP biopsy is a streamlined, outpatient procedure that usually takes about 20 to 30 minutes.

1. Numbing: The urologist applies a local anaesthetic to the skin of the perineum and the deeper tissues around the prostate.
2. Imaging: An ultrasound probe is placed in the rectum to provide a clear image of the prostate.
3. Sampling: Using the ultrasound as a guide, a fine needle is passed through the numbed skin of the perineum to collect small tissue samples.
4. Targeting: If you have previously had an MRI, the specialist will reference the images in targeting specific suspicious areas (cognitive fusion/MRI fusion prostate biopsy).

Recovery and Aftercare

Recovery from an LATP biopsy is generally very quick.

• Sensation: As the anaesthetic wears off, you may feel some dull soreness in the perineal area, which can be managed with standard over-the-counter pain relief.
• Minor Symptoms: It is normal to see a small amount of blood in your urine or bowel movements for a few days, and in your semen for several weeks.
• Activity: You should avoid heavy lifting and strenuous exercise for about 48 hours to allow the area to heal.
