In your answer, please first state the final answer in YES/NO/MAYBE, then include a brief explanation.

### Question: Urological concerns: Should trans-urethral catheter be located over or under the thigh?

### Context: 1: Bladder catheterization is a common practice after several surgical procedures; a wrong trans-urethral catheter position can affect the outcomes of some urological maneuvers. We assess with a physical model the variation of intra-vesical pressures due to different locations of the catheter.
2: Using a plastic bag fulfilled with 5l of normal saline, we try to reproduce bladder condition assessing pressures in case of catheter located over or under the thigh.
3: In case of catheter over the thigh, the flow of liquid is not allowed, and only a pressure of 23 cm of water induces the passage of fluid.


###Response: A wrong catheter position may adversely affect intravesical pressures; this finding has to be taken into consideration, especially when dealing with post-urological surgery catheterization.
