Nephrology focuses on diagnosing and treating kidney diseases. The kidneys filter waste, balance fluids, regulate blood pressure, and manage acute and chronic conditions.

Successful peritoneal dialysis relies heavily on prevention. Since the treatment involves a direct line into your body, the biggest risk is infection. However, infection is not inevitable. With rigorous hygiene and careful attention to detail, many patients go years without a single complication. “Care” in this context extends beyond the catheter; it involves caring for the whole body through diet, lifestyle, and emergency preparedness. By adopting these preventative habits, you protect your ability to stay on this home-based therapy and maintain your independence. This section covers the essential protocols that keep you safe and healthy while living with PD.
The most important rule in PD is “Don’t touch the tip.” The ends of your catheter and the transfer set must remain sterile at all times. Contamination happens when bacteria from your hands, breath, or environment touch these connections.
To prevent peritonitis (infection of the lining), you must wear a mask every time you connect or disconnect to prevent germs from your nose and mouth from falling onto the tubing. You must wash your hands thoroughly and use hand sanitizer. You should turn off fans and close windows to stop dust from blowing around. If you accidentally touch the tip of the tube, you must stop immediately and use a new cap or call the nurse. It is better to waste a bag of fluid than to risk an infection.
The exit site is where the catheter leaves your body. Keeping this area healthy is vital. A daily routine is required. You should wash the site gently with antibacterial soap and water in the shower or at the sink. Do not scrub it hard.
After cleaning, dry it thoroughly. Moisture allows bacteria to grow. Most clinics recommend applying a specific antibiotic cream (like mupirocin or gentamicin) around the exit site to kill bacteria. Finally, the catheter should be immobilized. This means taping it down or using a special belt so it doesn’t tug or pull when you move. Constant movement can irritate the hole, making it wider and more prone to infection.
Diet on PD is generally more liberal than hemodialysis, but it still requires attention. Because you lose protein in the drained fluid, you actually need to eat more, not less. High-quality protein like eggs, fish, poultry, and meat helps your body repair tissues and fight infection.
Phosphorus remains the adversary. It weakens bones and causes itching. You will likely need to limit dairy, nuts, and processed foods and take “binders” (pills) with meals to block absorption. Potassium is intriguing in PD because the treatment runs daily, and it removes potassium well. Some PD patients actually need to eat more potassium (tomatoes, potatoes) to keep levels normal, unlike hemodialysis patients who must restrict it. Your monthly labs will guide this.
Even though PD removes fluid well, you cannot drink unlimited amounts. If you drink 3 liters but the machine only removes 2, you will swell up. You must balance your “in” (drink) with your “out” (urine + ultrafiltration). Limiting salt is the best way to manage thirst. If you don’t eat salt, you won’t be thirsty, and you won’t gain excessive fluid weight.
One of the biggest perks of PD is the ability to travel. You are not tethered to a local center. For short trips, you can throw a few boxes of manual bags in the trunk of your car. For longer trips or flights, the supply company can ship your solution directly to your hotel or destination anywhere in the world.
You can take your cycler machine on an airplane as a carry-on medical device (it doesn’t count against your luggage limit). When staying in hotels, just ask for a clean area to set up. This freedom allows patients to visit grandkids, go on business trips, or take vacations, which is crucial for mental health and feeling “normal.”
Living with a medical device means being prepared for the unexpected. You should always have an emergency kit. This includes clamps (in case a line breaks), extra caps, a mask, and hand sanitizer.
You should know what to do if the power goes out (have manual bags ready). You should have a plan for natural disasters—keeping a week’s supply of fluid on hand at all times is recommended in case delivery trucks can’t reach you. Furthermore, keep your nephrologist’s on-call number in your phone. Knowing you are prepared reduces anxiety and ensures you can continue life-saving treatment even when things go wrong.

Do not continue the connection. Cap it off with a new sterile cap if possible. Call your clinic immediately. They may need to change your transfer set or give you prophylactic antibiotics.
Yes. The catheter can be taped down so it is not in the way. Intimacy is safe and does not harm the dialysis or the partner.
The boxes are heavy and sturdy. You can stack them high against a wall. Just make sure the lot numbers are visible so you use the oldest ones first (rotation).
Many clinics permit you to sleep with your pets in the bedroom, as long as you have already completed and secured the connection. However, during the actual hook-up time, pets must be out of the room.
