Management of Persistent Hematuria After Indwelling Catheter Replacement
The next step in management for this 72-year-old man with persistent hematuria after catheter replacement and initial bladder irrigation should be continuous bladder irrigation (CBI) with normal saline.
Assessment of the Current Situation
When evaluating persistent hematuria after catheter replacement, several factors must be considered:
- The patient is elderly (72 years old)
- The catheter was traumatically removed (pulled out)
- A replacement catheter was inserted
- Initial bladder irrigation was performed but bleeding continues
- The hematuria has persisted for several hours
Management Algorithm
1. Immediate Management
- Initiate continuous bladder irrigation (CBI) with normal saline
- This helps prevent clot formation and maintains catheter patency
- Use a three-way Foley catheter if not already in place
- Adjust flow rate to keep drainage pink or light red (not dark red)
2. Concurrent Assessment
- Monitor vital signs for hemodynamic stability
- Check hemoglobin/hematocrit to assess blood loss
- Evaluate coagulation profile if bleeding is significant
- Review medication history for anticoagulants/antiplatelets
3. Escalation of Care if Bleeding Persists
If hematuria continues despite CBI:
- Consider manual bladder irrigation with larger volume
- Increase size of catheter if necessary (22-24 Fr)
- Consider aminocaproic acid for persistent bleeding 1
- Obtain urological consultation for possible cystoscopy
Evidence-Based Rationale
Traumatic catheter removal and replacement commonly causes some degree of bleeding, but persistent hematuria requires active management. While some degree of hematuria is expected after catheterization, significant or persistent bleeding is abnormal and requires intervention 2, 3.
Continuous bladder irrigation is the standard first-line treatment for persistent hematuria in patients with indwelling catheters. This approach helps prevent clot formation, which can lead to catheter obstruction and urinary retention 4. The American College of Radiology guidelines support this approach for managing catheter-related hematuria 4.
Special Considerations
Potential Complications to Monitor
- Clot retention causing catheter obstruction
- Bladder perforation (rare but serious complication)
- Urinary tract infection
- Anemia from significant blood loss
When to Escalate Care
Urological consultation should be sought if:
- Hematuria persists despite continuous bladder irrigation
- Patient develops hemodynamic instability
- Large clots continue to form despite irrigation
- Pain develops or increases significantly
Medication Considerations
If the patient is on anticoagulants or antiplatelets, consider:
- Consulting with the prescribing physician about temporary adjustment
- More aggressive irrigation protocol
- Earlier urological consultation
Common Pitfalls to Avoid
- Delaying continuous irrigation - Waiting too long can lead to clot formation and catheter obstruction
- Inadequate irrigation flow - Flow must be sufficient to keep urine pink/light red
- Failure to monitor hemodynamic status - Significant blood loss can occur through urinary tract bleeding
- Overlooking underlying pathology - Persistent bleeding may indicate bladder injury or underlying pathology requiring further evaluation 5
In elderly patients with traumatic catheter removal, continuous bladder irrigation provides the most effective immediate management while allowing for assessment of the need for further intervention.
