(UroToday.com) Karim Bensala, MD, Ph.D., began his talk discussing the evolution of small renal masses (SRMs). The DISSRM registry has shown that 80% of SRMs have a less than 0.5 cm/year growth rate, and 30% remain stable1 (Figure 1). 35% of SRMs do not grow at all, and there is no correlation between low growth rate and initial tumor diameter.
