Percutaneous antegrade bilateral dilation and stent placement for internal drainage.
The authors describe a percutaneous method of establishing a channel betweeen the ureter and bladder across an obstruction. This technique, which involves a balloon catheter and placement of pelvivesical stents to provide internal drainage, is useful when the underlying disease contraindicates surgery and when retrograde catheterization from the bladder has failed. Palliation is achieved with little discomfort or risk to the patient.
