Management of Dislodged Nephrostomy Tubes

Immediate Actions and Medical Management Protocol

If a nephrostomy tube falls out, immediate medical attention is required, and the patient should cover the site with a clean dressing and proceed to the emergency department promptly for evaluation and replacement of the tube, as recommended by The Journal of Urology 1, 2
Evaluate for signs of infection, such as fever, flank pain, or purulent drainage, and assess for significant bleeding from the nephrostomy site, following guidelines from the American College of Radiology 3, 4
Determine how long the tube has been dislodged, as timing affects management approach, according to The Journal of Urology 1, 2

For delayed presentation (>24 hours), the tract likely has begun to close, requiring new percutaneous access, and imaging (ultrasound or CT) should be performed to assess for hydronephrosis and guide replacement, as suggested by The Journal of Urology and the American College of Radiology 1, 2, 3, 4
Retrograde ureteral stent placement should be attempted if the underlying condition allows for this approach, as recommended by The Journal of Urology 1, 2
If stent placement fails and the kidney is obstructed, a new percutaneous nephrostomy tube must be placed, according to The Journal of Urology 1, 2

Monitor for signs of infection, such as fever, increased pain, or purulent drainage, and bleeding, as some hematuria is common after replacement but should not be severe or persistent, following guidelines from the American College of Radiology 3, 4
In unstable patients with complete ureteral obstruction, prompt nephrostomy tube replacement is critical to prevent further renal damage, as recommended by The Journal of Urology 1, 2
For patients with malignant obstruction, re-evaluation of the need for continued drainage versus alternative approaches may be appropriate, as suggested by the American College of Radiology 3
