Question




What does these show?

Show answer

Images (a) show an avascular anechoic cyst in the upper pole of the kidney. Image (b) shows a septated cyst at the lower pole of a kidney. These correspond to the sites of the LPN.

What is the incidence of finding this?

Show answer

In this paper, cysts were found after 61/125 (48.8%) of procedures – so this is a common finding. Most were simple cysts.

What was the natural history of these cysts?

Show answer

In this series (at a mean of 4 years), 21% disappeared; 43% did not change significantly; 28% reduced in size and only 8% enlarged. This justifies a conservative management approach.
