Overview
Early diagnosis of hydronephrosis is important because most of the cases can be reversed if treated promptly which can prevent irreversible renal injury. Renal ultrasonography is the diagnostic study of choice for the diagnosis of hydronephrosis.
Ultrasound
- Renal ultrasonography is the diagnostic study of choice for the diagnosis of hydronephrosis.[1]
- The following results of ultrasonography is confirmatory of hydronephrosis:[2][3][4][5]
- Hypoechoic fluid displaces the echogenic sinus fat
- Anechoic black area
- Can detect dilation of the proximal renal pelvis of the kidney due to obstruction
- Can detect dilation of the renal pelvis and calyces of the kidney due to obstruction
- Can detect thinning of the renal cortex
