title: Use of a snare wire to perform nephrostomy access in the presence of obstructive staghorn calculi.
abstract: We describe a technique for gaining access to the central collecting system via a chosen calyx, utilizing an alternative entry point to that calyx. An Amplatz nitinol loop snare is then used to convert this access to a traditional approach.
