title: Comparison of cystometrograms and urethral profiles with gas and water media.
abstract: Twenty-five female patients were studied using both gas and water media for custometrograms and urethral profiles. The results showed that gas and water did not generate equivalent data in either cystometrograms or urethral profiles. The cystometrogram data showed a high correlation of data between gas and water, with gas values consistently lower than water values. Urethral profile data with gas were very difficult to interpret in terms of water-generated data, and correlations were tenuous at best.
