Renal arterial resistive index as a prognostic marker in lupus nephritis patients.

Introduction: Lupus nephritis (LN) is known to be one of the most serious complications of SLE and it is a major predictor of poor prognosis. Despite the improvement in understanding the pathophysiology of lupus nephritis and greater improvement in diagnostic approaches, lupus nephritis patients have poorer outcomes.

Objectives: Study the relation between renal resistive index (RRI) and renal function and histopathological parameters in lupus nephritis (LN) patients.
