为了解前列腺增生症（BPH）并发急性尿潴留与未并发尿潴留者血清前列腺特异性抗原（PSA）的变化，对21例BPH并发急性尿潴留及24例BPH未并发尿潴留者术前血清PSA进行了对比观察。结果显示BPH并发急性尿潴留组血清PSA异常者占76．2％，平均血清PSA为14．2μng／L，其中PSA＞10．0μg／L者占52．4％。BPH未并发急性尿潴留级血清PSA异常者占37．5％，平均血清PSA为5．1μg／L，其中PSA＞10．0μg／L者仅占8．3％。两组比较有极显著性差异（P＜0．01）。认为BPH并发急性尿潴留者的血清PSA可明显升高。
To understand the changes of serum PSA in patients with benign prostatic hyperplasia (BPH) complicated by acute urinary retention and non-concurrent urinary retention, 21 patients with BPH complicated with acute urinary retention and 24 patients without BPH with preoperative serum PSA Conducted a comparative observation. The results showed that BPH patients with acute urinary retention group had an abnormal serum PSA level of 76.2% and a mean serum PSA level of 14.2μng / L, with PSA> 10.0μg / L accounting for 52.4%. BPH without acute urinary retention grade serum PSA abnormalities accounted for 37.5%, the average serum PSA was 5.1μg / L, of which PSA> 10.0μg / L accounted for only 8.3%. There was significant difference between the two groups (P <0.01). Serum PSA in BPH patients with acute urinary retention may be significantly elevated.
