Renal artery pseudoaneurysms and arteriovenous fistulae most often occur as an iatrogenic complication. The article discusses a case of a patient diagnosed with an arteriovenous fistula and a pseudoaneurysm. A 64-year-old woman was admitted to the hospital due to nonspecific pain in the lumbar region. Imaging showed a typical picture of clear cell renal carcinoma. The patient was qualified for surgical treatment. After tumor resection, the patient developed microhematuria. Arteriovenous fistula and renal pseudoaneurysm were diagnosed using Doppler and computed tomography scans. The patient was qualified for arteriography with simultaneous embolization of the lesion. A follow-up evaluation confirmed the exclusion of aneurysm and fistula. Treatment outcomes were monitored using Doppler ultrasound. Doppler ultrasonography is the first method of choice in detecting and monitoring renal artery irregularities. Safety, non-invasiveness and easy access to this tool make it play a key role in the diagnosis of renal artery fistulas and pseudoaneurysms.
