title: Percutaneous approach to indeterminate caliceal filling defects.
abstract: Although the radiologic characteristics and endoscopic appearance of aberrant renal papillae have been described, a tissue diagnosis is the only way to exclude a low-grade urothelial malignancy. We report on three caliceal filling defects managed percutaneously in which biopsy findings confirmed aberrant papillae.
