Predictve Value of Computed Tomography in Diagnosing Stage of Renal Tumors

Abstract

Objective: To determine the frequency of true positive cases in staging of renal cell carcinoma
on computed tomography(CT) tacking histopathology as gold standard.
Methods: 75 patients diagnosed as RCC on CT underwent nepherectomies and
histopathological / radiological staging were compared.
Results: The overall sensitivity of CT for diagnosing RCC was 93.33%. For T1a 100%, for T1b
51.7%, for T2 80%, for T3a 75%, for T3b 2% and for T4 100%. The sensitivity for N1 and N2 is
66.67% and 80.2% respectively. CT showed higher stage in 43.3% cases.
Conclusion: Computed tomography is still a good diagnostic modality for pre-operative staging
of RCC and planning of surgery.
