Does baseline renal function always decrease after unilateral ureteral severe obstruction? —experimental validation and novel findings by Tc-99m diethylene triamine pentaacetate acid (DTPA) dynamic renal scintigraphy

摘要

BackgroundThere is a lack of consensus concerning changes in renal function after unilateral ureteral obstruction. The aim of this study was to assess the influence of ureteral obstruction on renal morphology and function and to explore the effectiveness of dynamic renal scintigraphy in evaluating obstructive renal function.
