Introduction:
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.
Materials And Methods:
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.
Results:
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.
Conclusion:
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.
