What is the most common problem associated with catheterization?

The most common problem associated with catheterization is indeed urinary tract infection (UTI). This occurs because the insertion of a catheter can introduce bacteria into the urinary tract, increasing the likelihood of infection. Catheters create a direct pathway for pathogens from the external environment into the bladder, which is normally a sterile environment. The risk of UTIs is particularly heightened when catheters are left in place for extended periods or when proper sterile techniques are not used during insertion and care.

Additionally, the presence of a foreign object like a catheter can disrupt the normal urinary barrier defenses, further contributing to the risk of infection. Symptoms of UTI can include frequency of urination, urgency, burning sensation during urination, and, in some cases, fever and chills if the infection ascends to the kidneys.

Other issues related to catheterization, such as blood clot formation, catheter blockage, and pain at the insertion site, are certainly possible complications but are far less common compared to the prevalence of UTIs. This highlights the importance of following strict aseptic techniques and proper catheter care protocols to minimize the risk of infection and enhance patient safety.
