      No, your kidneys do. The stomach does extract water from the food though. That water enters the blood and is used by cells, then extracted out of blood along with excess nitrogen in the kidneys.

      So it kind of depends on what you mean by "make urine." The energy in urine was created at the big bang. The elements were created in stars and supernovas. The water was mostly extracted in the stomach, and the nitrogen waste was produced in cells all over the body. However, the thing only becomes actual urine in the kidneys, so we say the kidneys make urine.

      Water is absorbed into the body via the large intestine, at which point it enters the bloodstream. Blood is then filtered through the kidneys.

      You cannot live without having at least one kidney.
      Here's why....
      So as the daughter of a man who worked with dialysis patients (kidney failure patients) your chances of survival without your kidneys is low. You will either need a kidney transplant or you will need dialysis. Dialysis won't prevent you from dying it will just allow you to live a little longer than having no kidneys at all.
      Hope you find this answer helpful. :>

      The waste component of urine is called Urea. If your kidneys stop working then that urea will build up and cause your body to stop functioning. It is toxic if not excreted through the kidneys. Therefore, the person needs dialysis to filter this urea (toxin) out of their body. The machine is doing the function of their kidneys. Person's can live on dialysis for years if they take care of their body through diet, exercise etc.

      your ureter is one of the most important things in the urinary system. It is a tube that transports urine from your kidneys to the bladder. If your ureter doesn't work, then you will not be able to pee. There are artificial ureters that can be put in your body if your ureter does not work.

      Kidney stones develop from concentrated urine minerals crystallizing. Factors include dehydration, diets high in oxalate, calcium, or uric acid, genetics, medical conditions like hyperparathyroidism, and lifestyle factors. Symptoms include severe pain, nausea, vomiting, and blood in urine. Treatment varies based on size and composition, including pain management, hydration, medications, lithotripsy, or surgery. Lifestyle changes and dietary modifications help prevent recurrence.🤒-hope this helps!
