Effect of Percutaneous Nephrolithotomy and Tract Dilatation Methods on Renal Function: Assessment by Quantitative Single-Photon Emission Computed Tomography of Technetium-99m–Dimercaptosuccinic Acid Uptake by the Kidneys

Abstract

QSPECT of (99m)Tc-DMSA confirms that renal function is preserved or often improved after percutaneous stone removal, and nephrostomy tract dilatation methods have similar effects on renal function.
