What imaging modalities can be used to perform a percutaneous drainage of renal or perinephric abscesses?

Percutaneous drainage of renal and perinephric abscesses can be performed with US, CT, or fluoroscopic guidance. US is usually preferred because it provides real-time imaging, which allows for an accurate, safe, and fast procedure. It is important to place the drainage catheter in the most dependent portion of a large abscess cavity to ensure complete drainage of infected material.
