1. Aim to investigate the pathological feature of UPA in Asians 2. To clarify the relationship between pathology, clinical phenotype, genetic mutation and surgical outcome of UPA in Asians. 3. To explore a new pathological type of unilateral primary aldosterone
The multi-center expert team led by Tracy Ann Williams formulated the International Consensus on the Pathological Diagnosis of Unilateral aldehyde disease, which standardized the pathological classification of unilateral PA. The previous retrospective study of the research group found that the pathologic types of unilateral primary aldosteronoma were mainly classical, and aldosteronoma was the most common. There was no significant difference in clinical features and postoperative biochemical remission rate between patients with classic and non-classic, but the clinical prognosis of the latter group was worse than that of the classical group. However, the study was retrospective and there may be inclusion bias. The pathologic distribution and clinical features of unilateral aldehyde disease are not completely clear and need to be discussed in prospective studies.Therefore，this study aims to determine the composition ratio of different pathological types in patients with unilateral procaldosis enrolled in our center. Gene mutation of different pathological types, the relationship between pathology and clinical phenotype, gene mutation, etc.
Study Type
OBSERVATIONAL
Enrollment
100
Whole slide images were created by scanning the complete histologic slide to produce high-resolution digital files of the histopathology of hematoxylin-eosin and CYP11B2 immunostained sections.Tissue sections of all blocks from each resected adrenal were evaluated by hematoxylin and eosin and CYP11B2 immunostaining and adrenal specimens were categorized as classical or nonclassical histopathologic findings of unilateral PA according to the HISTALDO consensus; Genotyping was performed using CYP11B2 (aldosterone synthase)-guided sequencing

RECRUITINGDefine the aldosterone-producing adenoma and aldosterone-producing nodule(classical)proportions
Adrenal operative specimens were diagnosed as aldosterone-producing adenoma、aldosterone-producing nodule、aldosterone-producing micronodules、aldosterone-producing diffusehyperplasia according to HE and CYP11B2 staining
Time frame: 2 weeks after surgery
The proportion with genetic mutations
The adrenal tumor was diagnosed by gene sequencing as KCNJ5 mutation, ATP1A1 mutation, ATP2B3 mutation or CACNA1D mutation,etc.
Time frame: 2 weeks after surgery
Analyze the Aldosterone level and renin level Characteristics
Aldosterone level（pg/ml）, renin level（uIU/ml）, blood potassium（mmol/L） and blood pressure are the main clinical indicators of primary aldosteronism(Aldosterone level divided by renin level to obtain ARR, ARR greater than 20 consider whether aldosterone autonomic secretion),different pathological types of aldosteronomas were measured to analyze whether there were differences in clinical characteristics of adrenal tumors of different pathological types
Time frame: 2 weeks after surgery
Define the ldosterone-producing micronodules and aldosterone-producing diffusehyperplasia(Nonclassical)proportions
Adrenal operative specimens were diagnosed as aldosterone-producing adenoma、aldosterone-producing nodule、aldosterone-producing micronodules、aldosterone-producing diffusehyperplasia according to HE and CYP11B2 staining
Time frame: 2 weeks after surgery
Analyze the blood potassium and blood pressure Characteristics
Primary aldosterone has varying degrees of hypertension with or without hypokalemia
Time frame: 2 weeks after surgery
