GU Interventions Genito-urinary (GU) interventions are imaging guided, minimally invasive procedures using needles, wires, and catheters to diagnose and treat obstructions and leaks of the urinary tract. Fluoroscopy is the most common imaging modality but CT and ultrasound can also be used to direct the procedure. GU interventions are used to gain access to the renal collecting system for diagnosis and treatment. Patients treated with this interventional radiology technique can avoid open surgery, as well as reduce the pain and recovery time involved in treating conditions of the urinary tract. Following is a description of the some of the procedures RCT physicians perform, along with images that show the dramatic results produced using these techniques.
A study used to evaluate the renal collection system by placing a thin needle through the patient's back into the kidney and injecting contrast (x-ray dye) to visualize the renal collecting system and ureter. Placement of a catheter (small tube) through the back into the kidney to drain the kidney. Placement of internal tube to drain kidney into the bladder. It is placed through the access of a percutaneous nephrostomy. Stone in the kidney or ureter can be removed through a percutaneous nephrostomy by a urologist using a scope or occasionally using a stone basket (a device used to capture a stone).
