title: Endoscopic stented ureterocystostomy.
abstract: OBJECTIVE
  Fibrotic or neoplastic obstruction of the terminal ureter and ureterovesical junction can preclude internal drainage with a Double-J catheter. Some minimally invasive alternatives are described in the literature to avoid a percutaneous nephrostomy. We present a pure endourologic technique.
  
  
  METHODS
  In six patients with an obstructed upper urinary tract, after the introduction of iodine contrast, the ureter was punctured with a needle to introduce a guidewire in the urinary tract under cystoscopic and fluoroscopic control. The alternative path between the bladder and ureter was then dilated up 10F to facilitate the Double-J catheter introduction.
  
  
  RESULTS
  All six patients had their obstructed urinary tract drained with a Double-J catheter inserted above the level of obstruction. No complication was verified.
  
  
  CONCLUSIONS
  Internal urinary tract drainage with a Double-J catheter was accomplished using endourologic principles in six patients, avoiding a percutaneous nephrostomy or other more invasive procedures.
