Role of linear tomography in evaluation of patients with nephrolithiasis.
One hundred twenty-four consecutive patients with suspected or known nephrolithiasis were referred for evaluation by linear tomography. Renal calculi were detected in 98 patients (79%). Linear tomography revealed more renal calculi than did preliminary KUB films in 46 patients (37%), although in only 10 cases (8%) was the tomogram positive if the KUB was negative. Exact quantification of the numbers and locations of renal stones is important in patients to be managed metabolically, and in those being evaluated in advance of or following percutaneous or extracorporeal lithotripsy.
