Brief Summary: During routine subtyping of confirmed primary aldosteronism by adrenal vein sampling extra plasma samples are drawn from both renal veins and from inferior vena cava. Plasma renin concentration and renin activity are analysed from these samples. Adrenal computed tomographies are analysed for cysts and other possible pathology by a blinded radiologist. Aim is to evaluate correlation between renal pathology and renin measurements.
Detailed Description: Aim of the study is to evaluate the prevalence of renal cysts and their association with renin concentrationand acitivity in samples from renal veins and inferior vena cava (IVC) in patients who undergo an adrenal vein sampling (AVS) because of primary aldosteronism.

In a prospective study up to 200 patients who have been referred to Tampere University Hospital for AVS are recruited during 24 months. Informed consent is taken. Clinical, medication, radiological and laboratory information according to Endcrine Society guidelines is collected. Interventional radiologist will draw venous blood from both renal veins and from IVC for later renin analyses. One, blinded radiologist will record renal pathology of cysts but also other abnormal radiologic features.

An interim analysis will be done when 60-100 patients have been recruited or at 6-12 months from the start of the study. Study will be stopped if significant difference can be found in renin measurement in patients with renal cysts compared with patients without renal cysts.
