What to do if a urinary catheter causes a urinary tract infection

Urinary tract infection after catheterization needs to be taken seriously as soon as possible. The infection can be confirmed by timely medical examination, and antibiotic treatment, keeping the catheter clean and increasing water intake can be used to treat it. Severe infection requires changing the treatment plan and nursing measures according to the doctor's advice.

1 Causes of urinary tract infection

Urinary tract infection is prone to occur after catheterization. The main causes include:

Physical stimulation: Long-term contact between the catheter and the urethra may damage the urethral mucosal barrier, making it easier for bacteria to invade.

Retrograde bacterial infection: Bacteria may be introduced into the urethra or bladder during the operation, or due to long-term indwelling urinary catheter, bacteria may retrogradely infect through the catheter.

Decreased immune function: Patients with weak body resistance or other underlying diseases such as diabetes are at high risk of urinary tract infection.

To prevent and deal with urinary tract infections, you need to understand the causes of infection and take proactive and targeted measures.

2 Treatment and care methods

Drug treatment: Urinary tract infections are mostly caused by bacteria and are usually treated with antibiotics. The doctor will choose the appropriate drug based on the urine culture results, such as fluoroquinolones such as levofloxacin, sulfonamides such as trimethoprim-sulfamethoxazole, or third-generation cephalosporins such as ceftriaxone.

Replace the urinary catheter: If the infection persists or the catheter itself is contaminated, the catheter must be replaced in time, and the aseptic technique during the catheterization process must be optimized to prevent reinfection.

Increase fluid intake: Encourage patients to drink plenty of fluids to increase urine output, which naturally promotes bacterial excretion and relieves symptoms of infection.

3 Daily care and prevention suggestions

Keep the catheter clean: Clean the catheter and surrounding skin with clean water and soap every day to prevent bacterial growth.

Pay attention to urination habits: change the urine bag regularly to avoid urine backflow. In addition, try to reduce the time of indwelling catheter and communicate with the doctor whether the catheter can be removed as soon as possible.

Strengthen immunity: Improve the body's ability to resist infection through a balanced diet, moderate exercise and adequate sleep, and assist in treatment.

Early diagnosis and treatment are crucial for urinary tract infection after catheterization. It is recommended that if symptoms such as fever, pain during urination, abnormal hematuria, and turbid urine occur, you should seek medical attention immediately to avoid further aggravation of the infection or kidney complications. During treatment under the guidance of a doctor, adhere to standardized care to minimize the recurrence of infection and lay the foundation for healthy recovery.
