Abstract

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.

超声和CT引导下经皮经耻骨后穿刺前列腺活检

以前没有经皮经耻骨后前列腺活检的病例被记录。一例74岁男性永久性造口患者，20年前因下行结肠癌行结肠切除术，报告排尿困难。筛查发现前列腺特异性抗原水平升高120.24 ng/mL。尽管直肠完好，但患者的肛门严重收缩或堵塞，无法进行直肠指检和经直肠超声探头的插入。经腹部超声引导下经耻骨后前列腺活检，同时使用计算机断层扫描监测针尖位置。随后病理分析证实为前列腺腺癌。结论本病例为首例经皮经耻骨后前列腺活检。
