"Key Points
  • The majority of nephrostomy tubes are placed for relief of urinary obstruction, and failure of catheters manifest with symptoms similar to what led to nephrostomy tube placement.
  • Treat nephrostomy tube infections as complicated cystitis or complicated pyelonephritis, but avoid treating asymptomatic bacteriuria, which is common.
  • Be mindful that nephrostomy tubes are often placed for obstructions caused by cancers—make sure the patient is not neutropenic if on chemotherapy.
  • Obtain fresh urine from the nephrostomy tube to send off for studies, rather than obtaining urine from the collection bag.
  • If an obstruction is suspected, try bedside troubleshooting with gentle irrigation of the catheter.
  • Hematuria is common in the first 2 days, but always consider a vascular injury or hematoma formation if hematuria persists or re-occurs after the urine initially clear.
  • In patients with decreased breath sounds or pleuritic chest pain ipsilateral to a recently placed nephrostomy tube, always consider pleural injury in your differential diagnosis."
