No previous instances of percutaneous transretropubic prostate biopsy have been documented.
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.
This case represents the first reported instance of a percutaneous transretropubic prostate biopsy.
此前尚无经皮经耻骨后前列腺穿刺活检的病例记录。
一名74岁男性患者有永久性造口，20年前因降结肠癌接受了结肠切除术，现报告有排尿困难。筛查检查发现前列腺特异性抗原水平升高至120.24 ng/mL。尽管直肠完好，但患者肛门严重狭窄或堵塞，无法进行直肠指检和经直肠超声探头插入。在使用计算机断层扫描监测针尖位置的同时，进行了经腹超声引导下经耻骨后前列腺穿刺活检。随后的病理分析证实为前列腺腺癌。
该病例是首例经皮经耻骨后前列腺穿刺活检的报告实例。
