Abstract

Purpose: The aim of this study was to define the clinical significance of transurethral resection of the prostate (TURP) in patients with benign prostate hyperplasia (BPH) and an elevated prostate-specific antigen (PSA) level.

Methods: We retrospectively evaluated patients with BPH, lower urinary tract symptoms (LUTS; International Prostate Symptom Score [IPSS]≥8), an elevated serum PSA level (≥4 ng/mL), and previous negative transrectal ultrasonography (TRUS) guided prostate biopsy. The PSA level after TURP was monitored by long-term follow-up. The tumor detection rate on resected prostate tissue, IPSS, maximal urinary flow rate (Qmax), and postvoid residual urine (PVR) were analyzed.

Results: One-hundred and eighty-six patients were enrolled. Histological examination of resected tissue by TURP revealed prostate cancer in 12 of these patients (6.5%). Among 174 patients without prostate cancer, the mean PSA level and the PSA normalization rate in 112 patients followed up at postoperative day (POD) 3 months were 1.26±0.13 ng/mL and 94.6%, respectively. The mean PSA level and the PSA normalization rate were 1.28±1.01 ng/mL and 95.7% in 47 patients at 1st year, 1.17±0.82 ng/mL and 97.1% in 34 patients at second years, and 1.34±1.44 ng/mL and 97.2% in 36 patients at third years of TURP. One patient showed a dramatic increase in the PSA level was diagnosed with prostate cancer at 7 years after TURP. IPSS, quality of life, Qmax, and PVR were improved significantly at POD 3 months compared to baseline (P<0.05), respectively.

Conclusions: TURP significantly reduced the serum PSA level, which was maintained for at least 3 years. This could be helpful to screen the prostate cancer using PSA value in the patient with previous negative biopsy and elevated PSA. In addition, TURP improves IPSS, Qmax, and PVR in patients with BPH, moderate LUTS, and an elevated PSA level.
