From the Guidelines
Managing blood in a nephrostomy tube requires prompt irrigation and aspiration to prevent clot formation and maintain patency, as recommended by the most recent guidelines 1. When managing blood in a nephrostomy tube, it is essential to assess the color and amount of blood present. Light pink-tinged urine is often normal, while bright red blood or clots warrant medical attention.
Key Considerations
- Increase fluid intake to 2-3 liters daily (unless contraindicated) to help flush the system and prevent clot formation 1.
- Ensure the drainage bag remains below the level of the kidney to maintain proper drainage.
- Avoid kinking or pulling on the tube, and secure it properly to prevent movement that could cause trauma.
- If blood clots are present and causing blockage, do not attempt to flush the tube yourself; instead, contact your healthcare provider immediately.
- Other concerning signs requiring immediate medical attention include severe pain, fever above 101°F (38.3°C), decreased or no urine output for several hours, tube dislodgement, or leakage around the insertion site.
Preventing Complications
Some blood in the urine is expected in the first 24-48 hours after tube placement as the kidney heals from the procedure. However, persistent or increasing bleeding may indicate complications such as infection, tube displacement, or injury to the kidney tissue, which require professional evaluation and treatment 1.
Irrigation and Aspiration
Irrigation with normal saline is recommended to prevent hemolysis, hyponatremia, and heart failure 1. In addition to irrigation, aspiration of blood clots may be necessary to maintain tube patency. This should be done under medical supervision to prevent further complications.
Monitoring and Follow-up
Regular monitoring of the nephrostomy tube and drainage system is crucial to prevent complications and ensure proper function. This includes checking for signs of infection, tube dislodgement, or leakage around the insertion site. By following these guidelines and taking prompt action when blood is present in the nephrostomy tube, healthcare providers can help prevent complications and ensure the best possible outcomes for patients 1.
From the Research
Managing Blood in a Nephrostomy Tube
To manage blood in a nephrostomy tube, several strategies can be employed:
- Irrigation of the tube to remove blood clots and prevent blockage 2
- Aspiration of blood from the tube to prevent accumulation and promote drainage
- Use of hemostatic agents, such as Quikclot®, to control bleeding in the kidney parenchyma 3
- Monitoring of the patient's hemoglobin and hematocrit levels to assess the severity of bleeding
Prevention of Bleeding Complications
Prevention of bleeding complications is crucial in patients with nephrostomy tubes:
- Careful patient selection and evaluation of coagulation status before the procedure 4
- Use of ultrasound or CT guidance during the procedure to minimize the risk of vascular injury
- Avoidance of overdistention of the bladder, which can exacerbate bleeding 5
Irrigation Fluids
The choice of irrigation fluid is important in patients with nephrostomy tubes:
- Normal saline is a safe and effective irrigation fluid, even in patients with renal failure 2
- Distilled water should be avoided due to the risk of hyponatremia and electrolyte disturbances 2
- The irrigation fluid should be used at a sufficient flow rate to maintain clear visualization of the surgical field and prevent blood clot formation 3
