Percutaneous Transretropubic Needle Prostatic Biopsy Under US and CT Guidance.

INTRODUCTION

No previous instances of percutaneous transretropubic prostate biopsy have been documented.

CASE PRESENTATION

A 74-year-old male patient with a permanent stoma, who had undergone colectomy for descending colon cancer two decades earlier, reported experiencing dysuria. A screening examination revealed an elevated prostate-specific antigen level of 120.24 ng/mL. Despite an intact rectum, the patient's anus was severely constricted or blocked, preventing both digital rectal examination and the insertion of a transrectal ultrasound probe. A transabdominal ultrasound-guided transretropubic prostate biopsy was conducted while monitoring the needle tip position using computed tomography. The subsequent pathological analysis confirmed prostatic adenocarcinoma.

CONCLUSION

This case represents the first reported instance of a percutaneous transretropubic prostate biopsy.
