A nephrostomy or pyelostomy tube, commonly known as a stent or catheter, is a medical device that is inserted through the skin into the renal pelvis or a calyx of the kidney. This procedure is essential for patients who require drainage of urine from the kidney due to various medical conditions that obstruct normal urinary flow. The process of changing a nephrostomy or pyelostomy tube involves several critical steps to ensure the continued functionality of the tube and the health of the patient. During the tube change, contrast material may be injected into the nephrostomy tube to facilitate imaging and ensure proper placement. The procedure is performed under fluoroscopic guidance, which allows for real-time visualization of the tube and surrounding structures. The existing tube is carefully removed, and a new tube is inserted to maintain drainage. This procedure is vital for preventing complications such as infection or kidney damage that can arise from prolonged obstruction or malfunction of the nephrostomy tube.
