What is A patient presented with ARF with complete anuria, but a normal ultrasound. Next investigation is: and explain in detail?
Answer is D (Radio-Renogram i.e. DTPA Scan) Radiorenogram is the next best investigation of choice. The next step would be to assess Renal function and the possible site of obstruction if that is the cause for anuria. The choice lies between an IVP or a Radio-Renogram. Out of these two a Radio Renogram is a distinctly better option. Imaging of the kidney and urinary tract have been greatly simplified by introduction of Radio nucleotide methods. These are now fast Replacing radiocontrast studies like IVP. Radionucleotide procedures are non invasive, highly sensitive and expose patients to less radiation.
