Final answer:
The student is likely requesting urgent diagnostic imaging to confirm the suspicion of renal vein thrombosis, indicated by the loss of specific proteins in the urine, and further evaluation for post-renal proteinuria.
Step-by-step explanation:
The student's concern suggests suspicion of renal vein thrombosis and is associated with loss of proteins such as antithrombin III (ATIII), protein C, and protein S in the urine, indicating a possible post-renal proteinuria where proteins are added somewhere in the urinary tract. This condition requires an urgent diagnostic imaging test which could be either a computed tomography (CT) scan or ultrasound (U/S). The presence of white blood cells in the urine often suggests a urinary tract infection (UTI), and symptoms like darkening of urine upon standing, abdominal pain, and vomiting can be related to various renal or post-renal conditions. For the diagnosis of renal failure, levels of creatinine and blood urea nitrogen (BUN) are checked, and renal ultrasonography is conducted to rule out obstruction.
