WebWhat happens if DCT is removed? 2 Answers. DCT removes any essential ions and salts from the urine before it gets excreted. Thus removal of DCT might lead to loss of these essential elements due to lack of absorption in the body. This might have severe clinical implications and lead to certain deficiencies of mineral ions in the body. The DCT is lined with simple cuboidal cells that are shorter than those of the proximal convoluted tubule (PCT).
