Brief Summary in Lay Language

Depending on their size there are different treatment options for renal stones. Size is mostly measured as maximum diameter. Since most stones are not spherical it would be more exact to rely on stone volumes.
Software-tools for the calculation of stone volumes based on CT-data have been developed but are not used regularly. There is no data about the accuracy of such tools. In this trial we investigate 100 stones from patients and animals from a stone collection.

The CT calculated volume is compared to manual measurements.

The volume is important for the choice of the appropriate treatment strategy.
