Hypertension is a frequent disease and renal artery stenosis, as a potential cause of hypertension, can be cured. Therefore, we frequently need to exclude a renal artery stenosis in patients with hypertension in our daily routine. This calls for a screening procedure which is non-invasive, highly effective and not too expensive. This paper describes the advantages and limitations of colour Doppler ultrasound in diagnosing renal artery stenosis. Colour Doppler ultrasound with intrarenal Doppler analysis is an ideal tool in the screening for relevant renal artery stenosis in patients with hypertension. This technique, however, requires a careful approach and extrarenal abnormalities need to be considered.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D012078	Renal Artery Obstruction	Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).

D015203	Reproducibility of Results	The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.

D018615	Ultrasonography, Doppler, Color	Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
