Document Summary
Removes wastes (urea, uric acid creatinine, ammonia) Maintains homeostasis (electrolyte, fluid and acid base balance) Us: non-invasive method showing renal parenchyma and pelvis structures without any contrast. Colour doppler can be used to assess the patency of renal vessels. Test of choice for urologic problems including urolithiasis, renal masses, urinary tract infection, trauma, and obstructive uropathy. It can be performed without iv contrast enhancement. Masses can be assessed by a triple-phase ct scan (unenhanced, arterial and delayed-phase acquisitions) Ct assess the response of the lesion using iv c+ Mr urography is less established than ct urography. The main role of renal mri is the assessment of renal arteries by mr angiography. The renal parenchyma, collecting system and vascular anatomy can be assess. The kidney functionally assess by using dynamic sequences. After iv c+, a peripheral cortical rim of high signal intensity can be seen.
