[Sonography, urography and angiography in kidney carcinoma. A comparative study]

Area of Science:

• Urologic oncology
• Diagnostic imaging

Background:

• Renal tumors require accurate diagnostic evaluation.
• Comparative analysis of imaging modalities is crucial for optimal patient management.

Purpose of the Study:

• To compare the diagnostic validity of angiography, sonography, and urography in evaluating renal tumors.
• To assess the incidence of renal vein occlusion and metastasis in renal tumors.

Main Methods:

• A comparative study involving 204 patients with renal tumors.
• Evaluation of findings from angiographic, sonographic, and urographic examinations.
• Analysis of tumor size, renal vein occlusion, metastasis, and varicocele presence.

Main Results:

• Angiography demonstrated 97% accuracy, sonography 96%, and urography 93%.
• Mean tumor size was 8.4 cm, with 25% causing renal vein occlusion.
• Tumor growth correlated with vein occlusion, which in turn correlated with urographic silent kidney. 20% of tumors had metastasized at diagnosis.

Conclusions:

• Angiography and sonography are highly valid methods for renal tumor evaluation.
• Renal vein occlusion is a significant complication, linked to tumor growth and diagnostic findings.
• Early diagnosis and staging are critical, considering metastasis rates and potential complications like varicocele.
