肾小管酸中毒(RTA)可分为Ⅰ型(dRTA,远端小管泌氢障碍),Ⅰ型(pRTA,近端小管重吸收碳酸氢钠障碍)、Ⅰ型(兼有Ⅰ、Ⅱ型机理)和Ⅳ型(伴肾小管对醛固酮反应性降低或醛固酮分泌不足而致高钾血症)。根据有无全身酸中毒表现分为完全性与不完全性,有无原发疾病分为继发性与原发性。本病起病隐匿,病程漫长,临床误诊时有发生,以致很多患者失去治疗机会,甚至造成
Tubular acidosis (RTA) can be divided into type Ⅰ (dRTA, distal tubular dysfunction), type Ⅰ (pRTA, proximal tubular reabsorption of sodium bicarbonate disorders), type Ⅰ And type Ⅳ (with tubular reactivity to aldosterone or aldosterone secretion caused by inadequate hyperkalemia). According to the presence or absence of systemic acidosis is divided into complete and incomplete, with or without primary disease is divided into secondary and primary. The disease occult onset, a long course of clinical misdiagnosis occurred, resulting in many patients lose treatment opportunities, and even caused
