The Porcine Bladder Model measures residual urine and mucosal suction of catheters with Micro-hole Zone Technology vs conventional eyelet catheters.1,2

This Is carried out through ex vivo testing with a porcine bladder*, where drained urine, intra catheter pressure and perceived mucosal suction is measured. A drop in the pressure indicates mucosal suction. The perceived mucosal suction was confirmed by the pressure peaks.1,2

* The lower urinary tract was extracted and used in the test, including the bladder, urethra, and ureters

See example of a filled male porcine LUT inside the pressurized tank.

Conclusion

Micro-hole Zone Technology catheters showed lower levels of mucosal suction and residual urine compared to conventional eyelet catheters, independent of the size of the catheter (CH10 – CH16).1,2

The Luja catheter showed significant lower level of mucosal suction compared to conventional eyelet competitor catheters - independent of size of catheter (CH10 – CH16) at 50 cmH2O

The Luja catheter showed significant lower level of mucosal suction compared to conventional eyelet competitor catheters - independent of size of catheter (CH10 – CH16) at 50 cmH2O

The Luja catheter showed significant lower residual volume at first flow stop compared to conventional eyelet catheter - independent of size of catheter (CH10 – CH16) at 20 cmH2O
