Summary:
- Reptiles like crocodiles, alligators, and snakes have a unique way of excreting waste that is different from mammals. Instead of producing urine, they produce a paste-like substance called uric acid.
- This uric acid can sometimes crystallize and form kidney stones in the reptiles' bodies, similar to how kidney stones form in humans.
- Studying how reptiles deal with and pass these uric acid kidney stones can provide insights into kidney stone formation and treatment in humans.
