Nephrostomy Tube Placement

When something blocks urine from leaving a kidney, pressure builds and can harm it. A nephrostomy tube — placed through the skin of the back directly into the kidney — drains urine into a bag until the underlying problem is treated. The procedure is done in the radiology department at Cape Cod Hospital and takes 1–2 hours.

What happens during placement

Using X-ray or ultrasound guidance, a needle reaches the kidney through numbed skin, a thin guide wire follows, and the drainage tube is passed over it. The tube connects to a drainage bag attached to your leg, and a dressing covers the site. You shouldn't feel pain — some pressure when the tube goes in is normal. Sedation may also be given.

Before the procedure: blood tests may be ordered, your diet is limited (clear liquids or nothing) for 4–8 hours beforehand, and an IV is placed for fluids and medication.

Afterward

  • Most patients go home 8–12 hours after the procedure; your vital signs are monitored for several hours first.
  • The insertion site may be tender for a few days.
  • A little blood in the urine for a few hours, and slight leakage at the site, are normal.
  • You'll be shown how to care for the tube — many patients have someone help with it.
  • How long the tube stays depends on why it was placed; your physician will give you the follow-up plan.
