Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal functions are not evaluate with there mehtads. 99mTc- DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75kidndys of 67 patients with confirmed renal tuberculous kidneys as 6types such as the type with small cortical defect, with parenchymal ulcerocavernous lesion, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspon-dings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates wre 19.0%, 18.4%, 7.9% 12%, 4.1%, 3.4%, respectively.
