    Area of Science:

    • Urology
    • Medical Imaging
    • Oncology

    Background:

    • Prostate cancer diagnosis often relies on biopsies.
    • Accurate needle placement is crucial for effective biopsy.
    • Limitations exist in conventional digital guidance for prostate biopsies.

    Purpose of the Study:

    • To evaluate the efficacy of transperineal prostate biopsy with continuous sonographic monitoring.
    • To assess the accuracy of sonographic guidance compared to digital guidance.

    Main Methods:

    • Transperineal prostate biopsy was performed in 25 patients with suspected prostate disease.
    • Continuous sonographic monitoring utilized a real-time rectal endoscopic probe with a longitudinal linear array.
    • Needle visualization from the perineum into the prostate was achieved.

    Main Results:

    • Sonographic guidance provided more accurate biopsy of clinically suspected nodules in 13 patients compared to digital guidance.
    • Subclinical prostate carcinomas were identified and biopsied in three patients.
    • Areas of atypical histology were also identified and biopsied in three patients.

    Conclusions:

    • Continuous sonographic monitoring during transperineal prostate biopsy enhances diagnostic accuracy.
    • This technique improves the detection of clinically significant prostate nodules and subclinical disease.
    • Sonographic guidance represents an advancement in prostate biopsy procedures.
