Abstract
ABSTRACTIntroductionNo previous instances of percutaneous transretropubic prostate biopsy have been documented.Case PresentationA 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.ConclusionThis case represents the first reported instance of a percutaneous transretropubic prostate biopsy.
