Which of the following statements is MOST ACCURATE regarding the pathophysiology behind bilateral obstructive nephropathy?
A. Glomerular filtration rate (GFR) is increased by increasing renal blood flow and decrease in tubular hydrostatic pressure Wrong Choice!
B. Sodium excretion is partially stimulated after relief of obstruction due to upregulation of atrial natriuretic peptide Correct Choice
C. Arterial blood gas will demonstrate a hypokalemic, metabolic alkalosis Wrong Choice!
D. Renal ultrasound is NOT a useful screening tool for obstructive uropathy due to low specificity Wrong Choice!
