Abstract

PURPOSE: The aim of this study was to identify the clinical baseline factors that affect failure of medical treatment(and especially surgical treatment) for benign prostatic hyperplasia(BPH) in spite of long-term medication.
MATERIALS AND METHODS
802 men who were over 50 years of age with BPH were enrolled for this study. Patients were allocated to a medication group and a surgical treatment group(after having at least a 12 month duration of medication). We compared the differences between the two groups for their initial International Prostate Symptom Score(IPSS), the uroflowmetry, the prostate volume, the postvoid residual urine and the serum prostate specific antigen(PSA).
RESULTS
397 patients had surgical treatment following medication due to BPH progression(acute urinary retention, aggravating LUTS) and 405 patients were given maintenance medical treatment during follow-up. Statistically significant differences were found in the IPSS(23.3+/-6.6 vs. 12.7+/-8.4), the prostate volume(53.5+/-28.1ml vs. 38.3+/-12.6ml), the maximal flow rate(7.8+/-4.7ml/sec vs. 12.7+/-5.4ml/sec), the postvoid residual urine volume(92.7+/-144.4cc vs. 36.5+/-147.1cc), and the PSA(6.1+/-7.6ng/ml vs. 2.8+/- 2.8ng/ml) between the surgical and medication groups. According to the area under the curve(AUC), the IPSS, prostate volume, maximal flow rate, postvoid residual urine volume and PSA are important in descending order. According to the receiver operating characteristic(ROC) curve- based prediction of the surgical intervention, the best cutoff value for the IPSS and prostate volume were 17(area under ROC curve: 0.83) and 40ml (area under ROC curve: 0.68), respectively.
Conclusions
The results show that BPH patients with more severe IPSS (>or=17) and a larger prostate volume(>40ml) have a higher risk of surgical intervention, and this suggests that the IPSS and prostate volume may be useful predictors at the initial visit for surgical intervention.
