What is a Page kidney?
Page kidney refers to the phenomenon of hypertension that develops following long-standing compression of renal parenchyma by sub-capsular renal collection, e.g. haematoma, seroma, urinoma.
What are the advantages and disadvantages of CT guidance for interventional procedures?
Advantages can safely access areas not well visualised on ultrasound vision is not obscured by gas better vision in larger patients is less user dependent for those less confident with ultrasound guided procedures the CT table in some ways offers more stable positioning for the patient in the intubated patient it allows for better monitoring and positioning of equipment Disadvantages is not truly dynamic like ultrasound, although CT fluoroscopy does allow near immediate imaging exposures the patient to ionising radiation requires a wider range of staff to undertake compared to ultrasound harder in the uncooperative patient as movement, means access point lost
Large BMI. Uncooperative patient. Ultrasound technically challenging. CT undertaken.
Multiple focal low attenuation areas in the right kidney, suggestive of a pyelonephritis and a subcapsular collection, with maximum depth of 3.5cm.
Poor venous access, resulted in a sub-optimal contrast enhanced scan - diagnostic discussion if subcapsular or perinephric collection.
Mass effect from the collection gives rise to an appearance of Page kidney.
