Use of vaginal pressure measurements in urodynamic testing

A study of 50 women using vaginal pressure measurements in urodynamic testing was performed. In the majority of patients, the vaginal pressure accurately reflects events occurring in the abdominal cavity. The elimination of abdominal pressure artifacts assists the physician in identifying patients with unstable bladders and assessing the voiding mechanisms. Vaginal placement of the pressure transducer is easier than rectal placement and better tolerated by patients.
