Professional assessment by a urologist is crucial for determining the appropriate treatment approach based on individual circumstances, catheter type, and infection severity.

The cornerstone of catheter-associated UTI treatment involves targeted antibiotic therapy. Unlike simple UTIs, CAUTIs often involve more resistant organisms requiring careful antibiotic selection. Treatment typically begins with empiric antibiotics based on local resistance patterns, followed by adjustment according to culture results. Common organisms include E. coli, Klebsiella, Pseudomonas, and Enterococcus species.

Proper catheter management is essential for successful treatment. This may involve catheter replacement if the device has been in place for extended periods, as biofilms can form on catheter surfaces harbouring bacteria. In some cases, intermittent catheterisation may replace indwelling catheters to reduce infection risk. The timing of catheter changes relative to antibiotic initiation requires careful consideration.

For complicated infections or those involving resistant organisms, combination antibiotic therapy may be necessary. This approach targets different bacterial mechanisms simultaneously and can be effective for polymicrobial infections. Adjunctive treatments such as bladder irrigation or antiseptic solutions may be considered in specific cases.

Before initiating treatment, comprehensive evaluation is essential. This includes obtaining urine samples for culture and sensitivity testing, preferably from a freshly placed catheter or through proper sampling techniques. Blood tests may assess kidney function and infection severity. Medical history review focuses on previous UTIs, antibiotic allergies, and current medications. Imaging studies such as ultrasound may be necessary if upper tract involvement is suspected.

Treatment typically begins with empiric antibiotic therapy while awaiting culture results. Oral antibiotics suffice for uncomplicated cases, while intravenous therapy may be necessary for severe infections. The catheter management plan is implemented, which may include immediate replacement or scheduled changes. Patients receive education about symptom monitoring and when to seek urgent care. Treatment duration typically ranges from 7-14 days depending on severity and organism.

Following antibiotic initiation, patients are monitored for clinical improvement within 48-72 hours. Temperature normalisation and symptom resolution indicate treatment effectiveness. Urine cultures may be repeated to confirm bacterial clearance. Catheter care protocols are reinforced, including proper hygiene techniques and drainage bag management. Follow-up appointments are scheduled to assess treatment response and address ongoing catheter needs.

During initial treatment, patients should monitor temperature regularly and maintain adequate hydration unless fluid restricted. Any worsening symptoms, including increased fever, severe pain, or confusion, require immediate medical attention. Antibiotic doses must be taken as prescribed without missing doses. Catheter drainage should be monitored for changes in urine colour or output.

Clinical improvement typically occurs within 3-5 days of appropriate treatment. Patients continue their prescribed antibiotic course even if symptoms resolve. Catheter care remains crucial, including maintaining a closed drainage system and ensuring proper bag positioning. Regular cleaning around the catheter insertion site prevents reinfection. Any new symptoms should prompt medical consultation.

For patients requiring continued catheterisation, prevention strategies become paramount. This includes considering alternatives like intermittent catheterisation when feasible, maintaining good catheter hygiene, and scheduling regular urological follow-ups. Some patients may benefit from prophylactic approaches or catheter-coating technologies. Lifestyle modifications supporting urinary health include adequate hydration and prompt treatment of any infection symptoms.

Antibiotic therapy may cause mild side effects in some patients. Gastrointestinal symptoms including nausea, diarrhoea, or appetite changes occur in 10-20% of cases. These typically resolve after treatment completion. Vaginal yeast infections may develop in women due to antibiotic effects on normal flora. Mild allergic reactions such as rash may occur but usually don’t require treatment discontinuation.

Serious antibiotic allergic reactions, though rare, require immediate medical attention. Development of antibiotic-resistant organisms can complicate future treatments. Clostridium difficile infection may occur with broad-spectrum antibiotic use, particularly in elderly or hospitalised patients. Kidney damage is possible if infections progress despite treatment, emphasising the importance of appropriate therapy and monitoring.

Our experienced urologists minimise these risks through careful antibiotic selection based on culture results, appropriate treatment duration, and close monitoring. Alternative antibiotics are available for patients with allergies or intolerances. Regular follow-up ensures early detection and management of any complications.
