title: Anatrophic nephrolithotomy: preservation of renal function demonstrated by differential quantitative radionuclide renal scans.
abstract: Differential quantitative radionuclide renal scans have been used to confirm that early removal of staghorn calculi by anatrophic nephrolithotomy preserves renal parenchyma without significant renal damage by the surgical procedure. The 99mtechnetium diethylenetriaminepentaacetic acid scan was useful in predicting recovery of function in the involved kidney, while the 131iodine orthoiodohippurate scan provided a quantitative evaluation of the effect of the surgical procedure on individual kidney function. All of 13 consecutive patients evaluated by 131iodine orthoiodohippurate renal scans had stable or improved effective renal plasma flow to the involved kidney and an unchanged or improved total excretory index 6 months after nephrolithotomy.
