Liu D, et al. - The value of unilateral pedal lymphangiography (LPG) plus computed tomography angiography (CTA) was evaluated by the experts in accurately depicting persistent idiopathic chyluria that was undetectable by ordinary contrast CT. Findings depicted that LPG plus post-LPG CTA characterized perirenal lymphangiectasia accurately that could not be demonstrated by routine contrast-enhanced CT or was not suitable for magnetic resonance imaging. Although an invasive method, it was noted as a good diagnostic alternative to LPG in patients with persistent chyluria requiring surgery.
