Renal/GU - Bear Paw Sign
Caption
A 43-year-old female presented to the ED reporting fever and left-sided flank and low back pain. HPI was notable for recurrent urinary tract infections. POCUS performed on the Left Upper Quadrant revealed severe hydronephrosis, with hypdronephrotic collections in the region of the calyces resembling the outline of a bear’s paw (referred to as “bear paw sign”). Subsequent abdominal CT confirmed severe hydronephrosis secondary to stenosis of the ureteroplevic junction (UPJ). Josiane Almeida
