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

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.
