What it shows

Kidney function and drainage, blockage.

Why it is done

Hydronephrosis, kidney donor work-up.

Preparation

A small radioactive tracer is injected or swallowed. Preparation depends on the test; tell staff if pregnant or breastfeeding, as feeding may need a pause.

Radiation & safety

Typical effective dose 1 to 2 mSv, similar to about 4 to 8 months of natural background radiation (about 3 mSv a year). Tell staff if you are or might be pregnant; the benefit usually outweighs the small risk, and shielding or alternatives can be considered.

How long it takes

about 1 hour. General information, not a diagnosis. Results must be interpreted by a qualified health worker.
