Role of ultrasound in urinary incontinence evaluation.

Transrectal ultrasound was used to assess anatomic support of the urethrovesical junction (UVJ) in continent and stress incontinent women. UVJ drop on straining of less than 1 cm as assessed by transrectal ultrasound correlated well with good support to the UVJ. Drop of UVJ of more than 1 cm on straining correlated with poor support to bladder neck and stress urinary incontinence. The transrectal technique is quick and easy to perform and interpret.
