Patients with elevated prostate-specific antigen (PSA) and no access to the rectum present a diagnostic challenge to the urologist. This study was undertaken to determine the efficacy of transperineal prostate biopsy using transurethral ultrasound guidance for the detection of prostate cancer.
Five men status post either total colectomy or abdominoperineal resection (age range: 58 to 73 years, mean age 65.8 years) were referred to us for the evaluation of an elevated PSA (range: 5.6 to 21.4 ng/dL, mean 16.1 ng/dL). Seven procedures were performed utilizing transurethral ultrasound to guide transperineal prostate biopsies in these men.
Biopsy results revealed benign prostatic hyperplasia in 4 procedures and prostate cancer in 3 procedures.
Transurethral ultrasound enables the practitioner to perform accurate sonographic assessment and precise biopsy of the prostate in such patients.
前列腺特异性抗原（PSA）升高且无法经直肠检查的患者给泌尿外科医生带来了诊断挑战。本研究旨在确定经尿道超声引导下经会阴前列腺活检在检测前列腺癌方面的有效性。
5例全结肠切除术或腹会阴联合切除术患者（年龄范围：58至73岁，平均年龄65.8岁）因PSA升高（范围：5.6至21.4 ng/dL，平均16.1 ng/dL）前来我院评估。对这些患者进行了7次经尿道超声引导下经会阴前列腺活检操作。
活检结果显示4例为良性前列腺增生，3例为前列腺癌。
经尿道超声使医生能够在此类患者中对前列腺进行准确的超声评估和精确的活检。
