Overview
Ultrasound may be helpful in the evaluation of hematuria. 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
Ultrasound may be helpful in the evaluation of hematuria. 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.[1]
Advantages
- Ultrasound of the abdomen and pelvis is safe.[2][3]
- US is good at:
- Detecting renal parenchymal lesions (e.g. renal cell carcinoma)
- Characterizing renal cyst
- Detecting renal calculi
- 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)
