RETROGRADE BALLOON CAUTERY INCISION OF URETEROPELVIC JUNCTION OBSTRUCTION

For the management of symptomatic ureteropelvic junction (UPJ) obstruc tion, retrograde balloon endopyelotomy has produced durable rates of a pproximately 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 accompli shing an endopyelotomy incision than an antegrade percutaneous or retr ograde ureteroscopic approach.
