RENAL DOPPLER ULTRASOUND

Service Description

Renal Doppler ultrasound is a specialized study that combines conventional ultrasound with color and spectral Doppler technology to evaluate the vascularization of the kidneys and main renal arteries. It is a non-invasive, painless, and radiation-free procedure that allows for the analysis of renal blood flow and the detection of hemodynamic alterations that may affect organ function. During the study, the renal, interlobar, and segmental arteries are examined, assessing their patency, flow velocity, vascular resistance, and any areas of stenosis (narrowing), partial or total occlusion, or alterations in parenchymal perfusion. Most frequent clinical indications: Suspected renovascular hypertension. Evaluation of renal artery stenosis or obstruction. Assessment of renal blood flow in chronic kidney disease. Post-surgical monitoring of kidney transplantation. Follow-up of patients with renal artery thrombosis or aneurysm. Complementary study in cases of alterations in kidney size or function. The exam allows for the early identification of vascular causes of hypertension or kidney dysfunction, providing essential data for medical or interventional treatment. Preparation: Fasting for 6 to 8 hours before the exam is recommended to reduce intestinal gas and improve visualization of renal and vascular structures. The procedure is outpatient and takes only a few minutes. 📍 Schedule your renal Doppler study and obtain a complete and accurate vascular assessment of renal function and blood flow.
