Overview
Ultrasound is easily available and cost-effective imaging modality that can be used at the bedside in the emergency setting. Ultrasound features in pyonephrosis include dilated pelvicalyceal system, echogenic debris, fluid-fluid levels in the collecting system. Ultrasound has high specificity but low sensitivity for diagnosing pyonephrosis.
Ultrasound
Ultrasound is an easily available, cost-effective imaging modality that can be used at the bedside in the emergency setting.
Ultrasound features in pyonephrosis include[1]:
- Dilated pelvicalyceal system
- Echogenic debris
- Fluid-fluid levels in the collecting system
- Dirty echoes of gas
Due to high specificity (100%) for diagnosing pyonephrosis by ultrasound but low sensitivity (62%), patients with sepsis and significant hydronephrosis should have sonographically guided percutaneous needle aspiration to confirm the diagnosis.[2][3]
