Significance and clinical value of the transitional zone volume (TZV) or index (TZI) in assessing the degree of lower urinary tract obstruction: Revisited

Conclusion Estimating the transition zone volume during TRUS is a reasonable way to obtain the required information about the TZI. Calculating the TZI could not be directly correlated with any of the different parameters, making the clinical value of such an index questionable. The observation that the obstructed and the retention groups both had a TZI above 0.5 deserves further research that can help in the classification of patients into obstructed and non-obstructed.
