Rationalization of interpretation of uroflowmetry for a non-caucasian (Indian) population: conceptual development and validation of volume-normalized flow rate index.

Aims: We intended to define volume-normalized flow rates (cQ; VQI) and to construct and validate uroflow (Q)-volume (V) nomograms in our Indian (non-Caucasian) population.

Methods: Prospective observational study.

Participants: Group A, male healthy volunteers 18-45 years without LUTS.
