PURPOSE: To assess the correlation between urodynamic parameters and urinary tract complications linked to benign prostatic enlargement (BPE), as well to assess the possible value of these parameters for predicting complications. METHODS: We retrospectively analyzed the relationship between the complications and correlative urodynamic data of 486 BPH patients. Multivariate stepwise logistic regression was used to identify major independent predictors and establish regression models. Receiver operating characteristic (ROC) curves were constructed to evaluate the models' predictive values. RESULTS: All of the individual parameters examined significantly correlated with most of the complications linked to BPE, except bladder calculus. According to ROC analysis, all of the areas under ROC curves (AUC), comparison of the individual parameters and the combined effects from the logistical regression models reached statistical significance (p < 0.05), and combining the parameters revealed a higher AUC compared to the individual parameters; however, all of the AUCs were below 0.9. CONCLUSIONS: Urodynamic parameters are significantly correlated with most of the complications linked to BPE, and these parameters have predictive value for the occurrence of these complications with limited values.
