One-shot IVU shows a barely discernible nephrogram on the right side and prompt uptake and excretion on the left side. What should be the next step to be done?   (A) Nephrectomy   (B) Isolate the proximal renal vessels, open the Gerota's fascia and explore the kidney   (C) Perform on table retrograde pyelography   (D) Perform on table angiography
