Catheter Balloon-trauma: Design, Development, and Ex-vivo Studies Using Intact Human Penis Specimens.

ABSTRACT:

Objective

To present a novel urethral catheter design with a pilot balloon to reduce intraurethral retention balloon inflation pressures and to provide a visual alert during catheter placement.

Methods

We manufactured our pilot balloon prototype from both molded and extruded silicone components. Various pilot balloon thicknesses were tested in order to determine the ideal compliance. We studied the filling pressures of the retention balloon of our prototype in a mechanical urethral model. The prototype catheter was then tested in ex-vivo human penis specimens obtained from gender affirming surgery and changes in the size of the retention balloon were measured under fluoroscopy.

Results

The thickness of the pilot balloon was directly related to the inflation pressure o
