Guidewire-Assisted Infundibular Tilt: A Technique for Access into Another Calix during Percutaneous Nephrolithotomy

Abstract

Sometimes, during percutaneous nephrolithotomy, a stone fragment migrates into a parallel calix, necessitating a separate puncture. We describe a simple technique for removing such fragments. This technique is especially useful for patients who have moderate to severe hydronephrosis where the intercaliceal parenchyma is thin.
