Those who fulfilled inclusion criteria were recruited. FNAC was done in accordance with stipulated clinical practice.Results: 53 patients with clinical and radiological suspicion of renal mass underwent FNAC of the kidney under ultrasound guidance. The age ranged from 1-2 year to 70 years (mean 44.7 years) with male to female ratio (1.9:1). Around 94.3% had primary renal mass, 1.9% metastatic tumor to the kidney and the rest 3.8% was undiagnosed.
