Usually stones are removed by retrograde endoscopic ureteroscopy. Occasionally a percutaneous antegrade approach may be indicated.
Indications for removing a stone in the ureter using percutaneous antegrade ureteroscopy:
(1) presence of a multiple impacted stones in the upper ureter
(2) presence of a stone in the renal pelvis in addition to the ureter
(3) presence of a ureteral stone following urinary diversion
(4) following a failed attempt to remove an impacted stone in the upper ureter using a retrograde approach
Percutaneous antegrade ureteroscopy should be considered if any of these conditions are present.
