Objectives:
The increased detection of such small-sized carcinomas has brought a number of new problems regarding the surgical approach to be adopted. We review our experience with 34 patients with small-sized renal carcinomas, comparing the US and CT data with histological findings.
Methods:
In a series of 150 cases of renal carcinoma, small sized carcinomas were diagnosed in 34 patients. All patients were examined by US and CT.
Results And Conclusion:
Five patients presented bifocal carcinomas. CT identified 100% of the small-sized carcinomas, failing only to identify the smaller carcinomas measuring less than 1 cm in diameter in the bifocal carcinoma cases, whereas US identified only 78.3% of the cases. The authors, moreover, mention the problem of multifocal tumours as an argument against performing a partial nephrectomy in the presence of two normally functioning kidneys, and believe it is advisable to reserve such conservative surgery for a selected number of cases.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
