[Preoperative radiologic evaluation of tumors of the renal parenchyma].
Renal cell carcinoma is frequently a matter of urological interest. In recent years there were significant improvements regarding the earlier diagnosis, more precise preoperative staging and appropriate therapy. One hundred patients (42-78 years old) with the preoperative diagnosis of renal cell carcinoma were analyzed. Preoperative radiological evaluation included: transabdominal ultrasound, intravenous urography, computer-assisted tomography, and angiography. In all patients after radical nephrectomy pathohistological diagnosis was established and patients with the confirmed renal cell carcinoma tumour staging was performed. All histological findings were compared with the preoperative results of radiological examinations. Reliability of all of them is separately determined. Our results confirmed that the most efficient method of preoperative staging was computer-assisted tomography (accuracy 93%). Diagnostic methods that were previously used like intravenous urography and angiography, were not useful for routine diagnostic purposes. Ultrasound is a precise but not an enough informative diagnostic tool (accuracy 87%). Combine used of both ultrasound and contrast computer-assisted tomography is cost-effective, and an enough precise combination for everyday use.
