Catheter-associated urinary tract infection (CA-UTI) is a urinary tract infection induced by the placement of a urinary catheter used to extract urine from the bladder. The components of the urinary system include the urethra, bladder, kidneys, and ureters. CA-UTI may develop if the drainage bag is not adequately emptied, if bowel movement germs contaminate the bag, if cleaning is uneven, or if urine from the catheter bag leaks into the bladder.

Furthermore, CA-UTIs have been linked to higher morbidity, mortality, healthcare expenditures, and duration of hospital stay. Reduce the risk of catheter-associated urinary tract infection (CA-UTI) by ensuring catheters are used only when necessary and removed as soon as feasible; catheters are put in using a good aseptic technique; and the closed sterile drainage system is maintained.


The following are some of the most prevalent symptoms of catheter-associated urinary tract infection:

  • Cloudy urine 
  • Urine with blood 
  • Constant and urgent need to urinate
  • Back discomfort, soreness, or spasms in the bottom area of your belly
  • Urine stench that is foul or overpowering
  • Flank pain
  • Fever
  • Chills
  • Mental alterations or perplexity (for an older person)


The following test is used to diagnose a CA-UTI:

  • Urinalysis. This is capable of detecting blood cells in your urine. Their presence might indicate an infection.
  • Urine culture. This test detects bacteria and fungus in your urine. Knowing what caused the infection can assist your doctor in treating it.

Sometimes your bladderb may not excrete pee rapidly enough. Even with a catheter, this may happen. Bacteria are more likely to proliferate in retained urine. The longer urine stays in the bladder, the higher the risk of infection. To determine whether you’re holding pee, your doctor may offer an imaging examination of your bladder, such as an ultrasound scan.


Catheter-associated urinary tract infections are often more resistant to therapy than other types of UTI. However, your physician will most likely prescribe antibiotics to eliminate any pathogenic germs. In the majority of situations, they are oral antibiotics. In the case of a critical disease, antibiotics may be administered intravenously. If bladder spasms are caused by the infection, your doctor may prescribe an antispasmodic to alleviate bladder discomfort.

In addition to helping you feel better, increasing your fluid intake can eliminate germs from your urinary system. Some liquids, such as alcohol, caffeinated beverages, and citrus fruit juices, should be avoided.
