If you need a prostate biopsy, you are facing two techniques with very different approaches. Transrectal is the traditional one. Transperineal image-fusion biopsy is the current recommendation of the EAU 2024 and AUA 2023 guidelines — with 95% fewer infections and greater diagnostic accuracy. This is an objective comparison to help you make an informed decision.
See visually why the transperineal route eliminates the infection risk associated with the transrectal route.
Analysis based on the latest evidence and the 2024 urology guidelines.
| Criterion | Transrectal (Older Technique) | Transperineal Fusion (Current Standard) |
|---|---|---|
| 1. Risk of infection / sepsis | 2–5% (High risk) | <0.5% (95% lower) |
| 2. Risk of bleeding | 1–2% | <1% |
| 3. Access to the anterior zone | Limited (often missed) | Excellent — reaches the entire prostate |
| 4. Diagnostic accuracy | Systematic, “blind” template | Real-time fusion — 30–50% more detections |
| 5. Need for antibiotics | Long course (3–5 days) | Usually a single dose |
| 6. Recovery time | 24–48h, simple restrictions | 24–48h, similar restrictions |
| 7. Cost / Coverage | Less expensive; covered by health insurance | Higher cost; covered when clinically indicated |
| 8. Current recommendation | Not recommended as first choice | Primary recommendation of EAU 2024 and AUA 2023 |
A closer look at the 4 pillars that made the transperineal route the worldwide gold standard.
The most important difference. The transrectal route carries bacteria from the rectum into the prostate and can cause sepsis. The transperineal route passes through the clean skin of the perineum, practically eliminating this risk (rates <0.5%).
The anterior region harbors up to 30% of significant cancers and is difficult to reach through the rectum. Because of the direction of the needle (from below upward), the transperineal route naturally reaches the entire gland.
Image fusion overlays the MRI onto the ultrasound in real time. Instead of shooting “blind,” the needle is aimed precisely at the suspicious lesion, detecting more intermediate- to high-risk tumors.
In 2024, the EAU (Europe) and the AUA (USA) began explicitly recommending: “transperineal access is recommended over transrectal access”, backed by large clinical studies (PRECISION, PROBE-PCa).
The typical step-by-step of a transperineal fusion biopsy in a hospital setting.
The patient arrives at the hospital’s operating suite, fasting. A pre-anesthetic assessment is carried out and an IV line is placed for complete safety.
Under deep intravenous sedation administered by an anesthesiologist, the software overlays the MRI images. Precisely guided samples are taken through the skin of the perineum, without puncturing the rectum. (Duration: 25-45 min).
Comfortable recovery in the post-anesthesia room for about 30 to 60 minutes. Discharge takes place the same day; you walk out normally, accompanied by a family member.
Use this checklist to talk with your urologist before the procedure.
A proper hospital environment and state-of-the-art equipment for your safety.
What men who chose the transperineal technique have to say.
“I was very worried about the procedure after reading about the risks of the old biopsy. The sedation with the perineal approach was very smooth; I felt absolutely nothing and went home the same day.”
Review via Doctoralia
“Dr. Bruno clearly explained the advantage of image fusion in my case, since my MRI showed a lesion in the anterior zone. A technical and transparent decision.”
Patient, Hospital Oswaldo Cruz
“Excellent facilities and an attentive team. The recovery was exactly as described in the consultation. I recommend it to anyone who puts safety first.”
Patient, Hospital Vila Nova Star
