Percutaneous removal of renal caliceal calculi: an alternative approach.
An alternative method is presented for the removal of caliceal calculi refractory to standard techniques. The involved calyx is punctured directly and dilatation performed to the stone without negotiating a wire into the renal pelvis. The stone is then removed under direct vision. This technique has been successfully used in 3 patients without complication.
