|
Purpose: We wanted to investigate how transurethral resection of the prostate(TURP), for treating patients with benign prostate hyperplasia(BPH), affected the serum prostate-specific antigen(PSA) levels. M
Materials & Methods: The serum PSA levels were measured before and 12 months after operation in 57 patients who underwent TURP for BPH. The total prostate weight, as measured by transurethral ultrasonography (TRUS), and the weight of the surgical specimen were examined in relation to the pretreatment PSA value and the changes in the PSA levels after the operation.
Results: The preoperative mean PSA density was 0.10±0.08ng/ml/cc. The postoperative serum PSA levels were decreased significantly after TURP (p=0.002). Removal of 1g of BPH tissue reduced the serum PSA levels by an average of 0.22±0.4ng/ml. The changes in the serum PSA level one year after TURP correlated with the resected chip weights[Y=0.406+0.176x (r=0.526, p＜0.05)].
Conclusion: TURP caused a long term decrease in the serum PSA level. One year after TURP, the PSA levels should be expected to decrease according to the resected chip weights.(Korean J Urol 2007;48:691-695)
