Trans-nephrostomy Ureteral Stent placement under fluoroscopy guidance: procedure and technique

#interventionalradiology #interventionalradiologypills #IRadiology Ureteral stents (also called J-J stents or double-J stents) are thin, flexible plastic, curled at both ends to avoid kidney and bladder injury and to prevent their dislocation. In the final position, the ureteral stent has the upper extremity in the kidney and the lower one in the urinary bladder. Anterograde ureteral stenting is the procedure, performed by interventional radiologist, in which a stent is inserted into the ureter through the skin and via the kidney, to allow urine to pass from the kidney to the bladder. In general, medical indications for ureteral stenting are the restoration of ureteral continuity in obstructive/infiltrative disease and ureteral preservation before surgery. THE PROCEDURE the patient lies on the bed in a prone position. Before the procedure, local anesthetic is administered. A needle is inserted into the urinary system through the kidney. A guidewire is inserted into the needle or into the nephrostomy tube if one was previously placed. Once the guidewire is placed into the urinary system a small catheter is used over the wire to reach the bladder. The wire is changed with a stiffer one and the stent is finally pushed into the bladder with the proximal extremity into the renal pelvis. #ureteralstenting #ureteralstent #urinaryinterventions #interventionalradiologyprocedure #stentinsertion #ureteralstentplacement #fluroscopystentplacement #urinarydisorders #urology #interventionaloncology #interventionalnews #nephrology #pain #proceduralpain #interventionalradiologylearning
