Lower Urinary Tract Symptoms (LUTS) after Transurethral Resection of the Prostate (TURP) occur in one-third of Benign Prostatic Hyperplasia (BPH) patients, may be caused by persistent prostatic inflammation and fibrosis.
This study aims to evaluate the role of inflammation and fibrosis in pathological mechanism of LUTS among patients with BPH who underwent TURP by assessing their PSA, TNF-α, and TGF-β level.
Design, Setting, and Participant:
Data in this study were analyzed with the 2-way hypothesis. The study used odds ratio to define the risk factors of LUTS after TURP. The samples of the study are BPH patients after TURP aged 50-80 years old.
Outcome Measurements and Statistical Analysis:
The data analyzed using SPSS version 21.0 for Windows.
Results and Limitations:
There were 34 cases of LUTS and 42 controls without LUTS. We found that there were an increased levels of TNF-α (> 46.95 pg/ml) (OR 55.6, 95% Confidence Interval [CI] 11.1-278.4, p=0.00) and TGF-β (> 207.63 pg/ml) (OR 16.7, 95%CI 5.3-52.8, p=0.00). The result of multiple linear logistic regression analysis obtained equation Y= 0.033 x TNF-α + 0.031 x TGF-β. Population Attributable Risk (PAR) % TNF-α is 60%, PAR % TGF-β is 53%.
Combination of elevated levels of TNF-α (>46.95 pg/ml) and TGF-β (>207.63) in prostate tissue is the risk factors for the occurrence of LUTS after TURP.
In this study, we enrolled 76 patients who were diagnosed with BPH and urinary retention. After TURP, there were 34 cases of LUTS and 42 controls without LUTS. We found that the levels of TNF-α and TGF-β between cases and controls were significantly different. We conclude that the combination of elevated levels of TNF-α and TGF-β in prostate tissue is the risk factors for the occurrence of LUTS after TURP.
