Why is bladder microtrauma a problem for IC users?
- A compromised bladder wall (epithelium) gives bacteria easy access to enter the epithelial cells and may increase the risk of UTIs.1
How does IC-related bladder microtrauma occur?
Mucosal suction is common when using conventional eyelet catheters1. The drainage of urine creates negative pressure inside the catheter that leads to the bladder mucosa getting sucked into the catheter eyelet in an abrupt and vigorous manner. This stops the urine flow, necessitating catheter repositioning, which may lead to scraping of the bladder mucosa.2
The mucosal suction raises concerns for potential microtrauma, considering that 4–6 catheterizations are performed by an IC user daily.2

Prior to use, refer to product labeling for complete product instructions for use, contraindications, warnings and precautions.
Luja Coudé is indicated for use by patients with urine retention and patients with a post void residual volume (PVR) due to neurogenic and non-neurogenic voiding dysfunction. The catheter is inserted into the urethra to reach the bladder allowing urine to drain. The product is for adult male patients only. Apply with caution if the patient produces urine with many particles clearly distinguishable by the naked eye, as it may lead to transient urine retention. See the device manual for detailed information regarding the implant procedure, contraindications, warnings, precautions, and potential complications/adverse events.
