Retrograde balloon cautery incision of ureteropelvic junction obstruction

For the management of symptomatic ureteropelvic junction (UPJ) obstruction, retrograde balloon endopyelotomy has produced durable rates of approximately 80%. This technique can be used with primary or secondary UPJ obstruction. With a RBE cutting balloon, the retrograde approach appears to be a far more rapid and potentially less costly (shorter OR time, hospital stay, no percutaneous nephrostomy) method for accomplishing an endopyelotomy incision than an antegrade percutaneous or retrograde ureteroscopic approach.
