Official Description

Injection procedure for pyelography (as nephrostogram, pyelostogram, antegrade pyeloureterograms) through nephrostomy or pyelostomy tube, or indwelling ureteral catheter

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

An injection procedure for pyelography involves the administration of contrast material through an existing nephrostomy tube, which is a tube placed in the kidney to drain urine. This procedure is specifically designed for radiological examinations of the nephrostomy tube, renal pelvis, and/or ureter. It is often utilized as a follow-up to assess the functionality of the nephrostomy tube or to investigate symptoms that may suggest a malfunction, such as pain, reduced urinary output, or leakage of urine around the nephrostomy tube insertion site. Prior to the injection, the area surrounding the nephrostomy tube insertion is thoroughly cleansed with an antibacterial solution to minimize the risk of infection. The drainage bag connected to the nephrostomy tube is then disconnected, and a syringe filled with contrast material is attached to the tube. The contrast is injected slowly, allowing for a detailed imaging study as the kidney and ureter fill with the contrast material, which is essential for diagnosing potential issues within the urinary system.

1. Indications

The injection procedure for pyelography is indicated for the following conditions:

  • Evaluation of Nephrostomy Tube Function This procedure is performed to assess the functionality of an existing nephrostomy tube, ensuring that it is effectively draining urine from the kidney.
  • Investigation of Symptoms It is utilized to identify the cause of symptoms that may indicate nephrostomy tube malfunction, such as pain, decreased urinary output, or urine leakage around the nephrostomy tube insertion site.

2. Procedure

The injection procedure for pyelography involves several critical steps to ensure accurate imaging and patient safety. First, the skin surrounding the nephrostomy tube insertion site is thoroughly cleansed with an antibacterial solution to reduce the risk of infection. This step is crucial as it prepares the area for the procedure and minimizes potential complications. Next, the drainage bag that collects urine from the nephrostomy tube is disconnected. This allows for a clear pathway for the contrast material to be injected. Following this, a syringe filled with the appropriate contrast material is connected to the nephrostomy tube. The contrast material is then injected slowly through the tube, which is essential for the imaging process. As the contrast fills the renal pelvis and ureter, it provides the necessary visualization for the radiological examination. This step is critical as it allows healthcare professionals to assess the anatomy and function of the urinary system effectively.

3. Post-Procedure

After the injection procedure for pyelography, it is important to monitor the patient for any immediate complications or adverse reactions to the contrast material. Patients may be advised to resume normal activities unless otherwise directed by their healthcare provider. Additionally, the nephrostomy tube should be reconnected to the drainage bag to ensure proper urine drainage. Follow-up imaging may be scheduled to evaluate the results of the pyelography and to determine if any further interventions are necessary based on the findings. Patients should also be educated on signs of potential complications, such as increased pain, fever, or changes in urinary output, and instructed to report these to their healthcare provider promptly.
