Introduction:
We analyze the efficacy of routine transition zone biopsies in patients undergoing ultrasound-guided systemic prostate biopsies for the first time because of a suspicious digital rectal examination or an elevated serum prostate-specific antigen (PSA) level.
Patients And Methods:
During systemic prostate biopsy two or four additional transition zone biopsies were performed in 192 consecutive patients: in 182 because of a serum PSA concentration >4.1 ng/ml and in 10 because of a suspicious digital rectal examination and a serum PSA level <4.0 ng/ml.
Results:
The overall prostate cancer detection rate was 37.5% (72/192). In 24 patients (33.3%), cancer was only detected in the peripheral zone, in 3 (4.2%) only in the transition zone, and in 45 (62.5%) in both zones.
Conclusion:
Transition zone biopsies performed at the first time of systemic prostate biopsy seem to have a low efficacy.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
