The predictive values of single and combined urodynamic parameters.

We calculated the predictive values of single urodynamic parameters with regard to five urodynamic diagnoses: genuine stress incontinence, mixed incontinence, motor urge incontinence, sensory urge, and no incontinence demonstrable. We now constructed tree diagrams by using the parameters with the highest predictive values (recursive partitioning analysis) and calculated the predictive values of the combinations of parameters in each subset. The tree diagrams and the predictive values of the combined urodynamic parameters offer insights into the relevance of different urodynamic parameters and can be used in developing programs for computer-assisted medical decision making in urodynamics.
