The aim is to To evaluate the adequacy of double energy CT (DECT) in foreseeing the arrangement of urinary stones with a solitary file (double energy proportion [DER]) and five files.

Patients going through DECT before dynamic urolithiasis treatment were tentatively selected the examination. Expectations of stone organization were made dependent on discriminant examination with a solitary file (DER) and five files (stone thickness at 80 and 135 kV, Zeff [the compelling nuclear number of the spongy material] of the stone, DER, double energy file [DEI] and double energy contrast [DED]). After extraction, stone piece was assessed by methods for physicochemical examinations (X-beam stage investigation, electron microscopy, wet science procedures, and infrared spectroscopy). A sum of 91 patients were incorporated. For calcium oxalate monohydrate (COM) stones, the affectability, explicitness, and generally speaking precision of DECT with one list. DECT is a promising device for stone piece appraisal. It took into consideration assessment of substance sythesis of all stone kinds with explicitness and exactness going from 85% to 100%. Five DECT records have shown much better analytic exactness contrasted with a solitary DECT file.
