Management of Small Renal Masses

When we started to plan this special issue, we were under the thought that we are facing more and more cases of small renal masses in our daily work as urologists and pathologists. This common fact nowadays will probably increase in the near future as radiological studies are more frequently ordered and fortunately we face an increase in longevity, and also as people can get to detect their renal masses before they really arrive to the classic lumbar pain/haematuria/lumbo-abdominal mass symptoms.
