Pitfalls
The rib shadows often obstruct visualization of the kidney; slight probe rotation
can mitigate this effect. The left kidney often requires a more posterior and
superior approach than expected. If localization remains difficult, having the
patient breathe deeply often causes inspiration to push the kidney into view.
