Introduction. The objective of this study was to establish the influence of preoperative parameters on unfavourable outcomes after transurethral resection of the prostate.
Materials and Methods. In a prospective study, ninety patients underwent transurethral resection of the prostate. The standardized protocol was used to investigate parameters, preoperatively and after six month. The baseline values were analyzed with respect to the probability of predicting the effectiveness of the outcome.
Results. All preoperative parameters changed significantly, from 55.1% to 116% (p<0.001). Treatment was effective for 85.6% of the patients, and the outcomes were unfavourable for 14.4%. The monovariate analysis detected the transition zone index (cut-off 0.48, p=0.002, OR 7.48) as independent predictor of ineffective outcome. Logistic regression analysis found two the most important parameters - transition zone index (OR 30.26, p=0.002) and bothersomeness of voiding symptoms (OR 20.7, p=0.008) for unfavourable outcomes.
Conclusions. The parameters that are traditionally used cannot predict unfavourable outcomes. The transition zone index and bothersomeness of voiding symptoms are most important parameters for predicting an unfavourable outcome after TURP
