Representative photomicrograph of the urinary sediment, stained with H/E, of a patient with nephrotic syndrome (a) (×200). Dotted arrows identify small cells; white indicates renal tubular epithelial cell, black indicates leukocyte. Head arrows identify large cells: white indicates urothelial cell, black indicates squamous cell. Continuous arrows identify medium cells: urothelial cells. b Proportions of small cells, i.e., renal epithelial tubular cells (RTEC) and leukocytes, in groups without ATN (Non-ATN), with ATN (ATN) and with glomerular proliferative lesion (PRO)
