The 68-year-old Kardashians matriarch broke down in tears last week while telling her family she needed to have her ovaries removed after doctors discovered a cyst and a "little tumour".
But she was then advised it would be "the best thing" for her health to have her ovaries and uterus removed to "not give anything a chance to grow anywhere".
Speaking in the latest episode of The Kardashians, Kris told friends Kathy Hilton and Faye Resnick: "I'm gonna have a hysterectomy.
"It started out as just getting some ovaries removed, and then today I got a phone call.
"They found something, we're here to fix it.
"I'm going to remove something that gave me six of the best parts of my whole life."
Kris - who has children Kourtney Kardashian, 45, Kim Kardashian, 43, Khloé Kardashian, 40, Rob Kardashian, 37, Kendall Jenner, 28, and Kylie Jenner, 26 - admitted she was feeling "very emotional" about the procedure.
In a teaser for the July 18 episode of The Kardashians, Kris told the cameras: "I'm done with my surgery, and I feel great!"
Last week, Kris was seen breaking down in tears on the reality TV show when she gathered Kim, Khloe and Kendall around and emotionally informed the trio about a tumour being found on her ovary.
