| ==Overview==
| |
| Ultrasound(US) offers an accurate, noninvasive approach to rule out [[obstructive uropathy]], determine renal size and cortical thickness, and look for masses or cysts. The availability of color duplex to assess renal vascular flow and resistance provides additional information regarding renal parenchyma.

| ==Ultrasound==
| |
| US is the first choice among the imaging studies to evaluate a patient with deterioration in [[renal]] function, because it does not involve the usage of [[nephrotoxic]] contrast media. US is the imaging test to consider in patients with suspected [[glomerular]] hematuria, as manifested by dysmorphic RBCs, proteinuria of at least 2+, and RBC casts. US is safe in pregnancy. It is less accurate in detecting ureteral lesions such as nonobstructing stones, and thus may not be the first choice for evaluating a suspected urological cause of hematuria.<ref>{{cite book | last = Rew | first = Karl | title = Primary care urology | publisher = Saunders | location = Philadelphia, Pa.

| * It is good at detecting
| |
| * Detecting renal parenchymal lesions (e.g. renal cell carcinoma)
| |
| * For characterizing [[Renal cysts|renal cyst]]<nowiki/>s Showing renal calculi
| |
| * For determining ureteric obstruction (Hydronephrosis)
| |
| '''Disadvantages:'''
| |
| * US is poor at detecting small lesions within the collecting system (e.g. urothelial cell carcinoma (UCC) of the renal pelvis)
