Chronic Indwelling Catheters are used to treat urine leakage in 5% to 10% of long-term care facility residents. They often have a complicated microbiological flora of two to five species and a biofilm on the catheter that may cause blockage. These inhabitants are invariably bacteriuric.
Compared to bacteriuric residents without chronic catheters, residents with chronic Indwelling Catheters have higher urine infection morbidity rates. Limiting the use of Indwelling Catheters for extended periods of time is the most efficient way to avoid infection. Although it is advised to manage these patients with proper catheter care and infection control measures, it has not been determined how these measures affect the likelihood of urinary infections or the avoidance of symptomatic episodes.
By paying attention to catheter care, particularly early detection and replacement of clogged Indwelling Catheters and prevention of catheter trauma, asymptomatic infection is probably preventable. Prior to invasive genitourinary surgeries, proper preventive antibiotic medication is also required. Treatment for asymptomatic bacteriuria is not necessary.
Patients should be assessed clinically and microbiologically when symptomatic episodes occur, and the right antibiotic medication should be administered. The frequency of urinary infections associated with chronic catheter usage will need to be significantly reduced, which will require further technological advancements in catheter material and urine drainage.
