THREE-DIMENSIONAL URETHRAL PRESSURE PROFILE

I. Experimental Study in Male and Female Dogs

Abstract

Many physicians usually record the Urethral Pressure Profil (UPP) using a special catheter with four eyes around the circumference of the tip, because the errors in reproducibility is small. Although, they can merely record the total urethral pressure, using the catheter with several eyes. In this paper we reported a newly designed catheter with only one eye around the circumference of the tip and the results of the prospective differences in the urethral pressure profile of the anterior/posterior and lateral walls of the male and female dogs. We might study the urethral components in three-dimensional respect.
We can put this catheter to the practical use in detecting the directional difference in urethral closure pressure, such as prostatic hypertrophy, dyssynergia of the external urethral sphincter, urethral stricture and etc.
