Urethral pressure profilometry in the anaesthetised bitch: a comparison between double and single sensor recording.
A comparison was made between urethral pressure profiles obtained using a single sensor and 'subtracted' urethral pressure profiles resulting from double sensor recordings in 50 bitches. There were small but significant differences in the functional profile lengths and maximum urethral closure pressures between the two types of recording. The differences were partially explained by a significant fall in the intravesical pressure recorded during profilometry and variations due to respiration. The profiles from single and double sensor recording were of equal significance in the diagnosis of sphincter mechanism incompetence.
