This work reports on age-matched urethral sphincter size comparison between continent and incontinent women based on intraurethral MR imaging. We also report on correlations between MRI findings and urodynamics which have not been previously documented. This work shows that although, the decrease in urethral sphincter volume has been associated with stress incontinence in women it is also associated with normal aging. There is high correlation between several urodynamics variables and MRI findings which promises that MRI may become an important adjunct tool in the evaluation of women with stress urinary incontinence.
