"We’re your body’s built-in water and waste wizards! Let’s take a deep dive into how we help keep you feeling fresh and fantastic!"
Katie & Kenny the Kidneys
Welcome to Katie & Kenny the Kidneys' world—where every drop of blood gets a
sparkling clean!
Katie and Kenny are the twin superheroes of your body, working together to filter out waste, keep your blood balanced, and make sure you stay healthy and full of energy.
They love a good splash, always busy filtering, sorting, and sending the good stuff back into your body while waving goodbye to what you don’t need.
Cleaning is their superpower, and they can’t wait to show you how they keep your body running smoothly!





Meet Katie and Kenny!
Katie and Kenny are always on duty, working as a super team to keep your body clean and balanced! They’re like tiny, hardworking filters, making sure everything inside you stays just right.
Whether you’re drinking water, munching on snacks, or running around the playground, they sort out what your body needs and flush away the stuff it doesn’t! They help keep your blood clean, make sure you don’t have too much or too little water, and even help balance important minerals that keep you strong.
💧 Did you know? Without your kidneys, waste and extra water would build up like a messy room with no cleanup crew! That’s why Katie and Kenny are so important—they work non-stop to keep your body fresh, healthy, and full of energy.
But sometimes, kidneys like Katie and Kenny need extra help. Some kids are born with kidneys that don’t work properly, while others might get sick over time. When that happens, doctors can step in with special treatments, and sometimes, a kidney transplant is needed. That’s where real-life heroes come in—people just like YOU who help by learning about kidney health, donation, and transplants!
A kidney transplant can be life-changing, helping someone feel strong and active again. Thanks to amazing donors, kids and adults who once felt tired and sick can go back to doing what they love—playing, learning, and having fun!
What Do Kidneys Do?
Katie and Kenny are two bean-shaped cleaning stations, tucked away in your lower back. But don’t let their size fool you—they are powerful little filters, working day and night to clean your blood and keep your body healthy.
They filter all the blood in your body about 50 times a day—that’s like filling up a whole swimming pool with clean water! They remove extra water, salt, and waste, turning them into urine, which then leaves your body. It’s their way of taking out the trash and making sure your body stays fresh and clean!
But Katie and Kenny’s job doesn’t stop there! They are also body balancers:
💧 Water Wizards – Making sure you have just the right amount of water, not too much or too little.
⚡ Mineral Masters – Keeping important minerals like potassium and calcium in check so your muscles and bones stay strong.
❤️ Blood Pressure Bosses – Helping to control your blood pressure so your heart can pump properly.
🩸 Red Blood Cell Helpers – Sending signals to your body when it needs to make more red blood cells to carry oxygen.
Now, imagine if Katie and Kenny weren’t working properly. If kidneys get sick, they can’t clean the blood as well, meaning waste and extra water start to build up, making it hard for someone to stay healthy. That’s when a hero can step in—someone who donates a healthy kidney to help another person get back to feeling strong and full of energy!
A kidney transplant can be life-changing, helping kids and grown-ups get back to playing, learning, and having fun—all thanks to real-life heroes who share the gift of health and happiness!
What is Kidney Dialysis?
Katie & Kenny’s Backup Plan!
Katie and Kenny the Kidneys work super hard to clean your blood, balance fluids, and get rid of waste—but sometimes, they need extra help. That’s where kidney dialysis comes in! 🏥💧✨
💡 Why Do People Need Dialysis?
When Katie and Kenny aren’t working properly, waste and extra water start to build up in the body, which can make someone feel really tired, sick, or swollen. Dialysis acts like a helpful machine that does the kidney’s job, cleaning the blood so the body stays healthy and strong!

🌀 How Does Dialysis Work?
There are two main types of dialysis, and both help clean the blood when the kidneys can’t:
1️⃣ Haemodialysis – The Blood Cleaner! 🩸
A special machine removes blood from the body, cleans it just like a kidney would, and then returns it fresh and clean. This usually happens a few times a week at a hospital or a dialysis centre.
2️⃣ Peritoneal Dialysis – The Tummy Helper! 🫧
Instead of using a machine, this type of dialysis happens inside the belly! A special fluid is placed in the tummy, where it absorbs waste and extra water, then gets drained away—helping keep the body clean.



💪 Living Life on Dialysis!
Even though dialysis means spending some time connected to a machine, kids can still go to school, play, and do all the things they love! It helps keep them strong, full of energy, and ready for their next adventure!
💜 The Ultimate Goal – A New Kidney!
Dialysis is like a backup plan while doctors look for a matching kidney for a transplant. When a new kidney is found, Katie and Kenny can get back to doing their job all on their own!
Thanks to amazing doctors, dialysis machines, and kidney transplants, kids who need a little extra help can keep living, playing, and enjoying life to the fullest! 🎉💖
Superpower of Donation
When someone donates a kidney, they give another person the chance to live a healthy, happy, and active life again! And here’s the amazing part—you only need one kidney to live a perfectly normal life, which means some superheroes donate while they’re still alive!
💧 How does it work? Doctors carefully place a donated kidney into the recipient’s body, giving them a fresh new filter to help clean their blood and balance their body. It’s like getting a brand-new water filter, making sure everything runs smoothly again!
With their new kidney, kids and grown-ups can go back to playing, laughing, and doing all the things they love without feeling tired or sick. They can run on the playground, swim in the pool, and enjoy their favourite foods without worrying about how their body will handle it.
And the best part? A kidney transplant isn’t just about feeling better—it’s about getting back to life! Kids can return to school, play with their friends, and dream big again. Adults can go back to work, travel, and enjoy time with family without feeling exhausted all the time.
Thanks to kind and generous heroes, a kidney transplant gives someone a fresh start, a healthier future, and a world full of new possibilities! 💙💧

Live Kidney Donation – A Superhero Gift!
Did you know that some heroes don’t have to wait until they’re gone to save a life? That’s right! Unlike other organs, a person can donate one of their kidneys while they are still alive—and still live a healthy, normal life with just one!
Katie and Kenny the Kidneys work as a team, but the amazing thing is, your body only needs one to do the job. That’s why some incredible people choose to donate one of their kidneys while they’re alive, giving someone else the ultimate gift of health, energy, and happiness!
How Does It Work?
When someone’s kidneys stop working properly, they might need a kidney transplant to survive. If a living donor (like a family member, friend, or even a kind stranger) chooses to donate one of their kidneys, doctors carefully place the donated kidney into the recipient’s body, giving them a fresh new way to filter their blood and feel strong again!
💧 It’s like giving someone a brand-new, top-of-the-line water filter! Instead of feeling sick and tired all the time, they can go back to playing, learning, laughing, and enjoying life—all because of a generous hero who shared the gift of life.
Living Kidney Donation:
A Gift That Keeps on Giving!
Because you only need one kidney to live a happy and healthy life, more people are choosing to become living donors to help their loved ones—or even a total stranger! It’s a gift that can change someone’s life forever.

Life After Transplant
With a new kidney, transplant recipients can go back to living life to the fullest—playing their favourite games, going to school, and spending time with family and friends without feeling sick or tired all the time! A healthy kidney means more energy, strength, and a fresh start for all the fun adventures ahead!
For kids, this means getting back to school, joining in recess games, and focusing on learning without worrying about feeling unwell. They can run, jump, and play sports without getting exhausted, and simple things like drinking water or eating their favourite foods become easy again! No more sitting on the sidelines—they can be part of the action!
For older kids and adults, a kidney transplant means getting back to work, enjoying hobbies, and travelling without constant doctor visits. They can do everyday things like taking long walks, going shopping, or even dancing at celebrations—all without feeling weighed down by sickness.
A kidney transplant isn’t just about feeling better—it’s about getting back to life! Thanks to an amazing donor, kids and grown-ups can enjoy every moment, chase their dreams, and live with freedom again! 💙💧

💙 Learn & Share: Superheroes spread knowledge! Learning about how kidney donation helps people live longer, healthier lives is a great way to start. But don’t stop there—share what you’ve learned with your family and friends! The more people who know about Katie and Kenny, the more heroes we have!

🚰 Remember Katie & Kenny! Next time you take a big sip of water or hear a flush, think about all the hard work your kidneys do! They never stop filtering, cleaning, and balancing to keep your body running smoothly. Every drop of clean blood is thanks to them!
Even the smallest heroes can make a big impact—just by learning, sharing, and taking care of their own kidneys. One day, you might help save someone’s life, just by being the amazing hero you already are! 💙💧✨
