For polycystic kidney disease, certain tests can detect the size and number of kidney cysts you have and evaluate the amount of healthy kidney tissue, including:
- Ultrasound. During an ultrasound, a wandlike device called a transducer is placed on your body. It emits sound waves that are reflected back to the transducer — like sonar. A computer translates the reflected sound waves into images of your kidneys.
- CT scan. As you lie on a movable table, you're guided into a big, doughnut-shaped device that projects thin X-ray beams through your body. Your doctor is able to see cross-sectional images of your kidneys.
- MRI scan. As you lie inside a large cylinder, magnetic fields and radio waves generate cross-sectional views of your kidneys.
Treating polycystic kidney disease involves dealing with the following signs, symptoms and complications in their early stages:
High blood pressure. Controlling high blood pressure can delay the progression of the disease and slow further kidney damage. Combining a low-sodium, low-fat diet that's moderate in protein and calorie content with not smoking, increasing exercise and reducing stress may help control high blood pressure.
However, medications are usually needed to control high blood pressure. Medications called angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) are often used to control high blood pressure.
- Pain. You might be able to control the pain of polycystic kidney disease with over-the-counter medications containing acetaminophen. For some people, however, the pain is more severe and constant. In rare cases, your doctor might recommend surgery to remove cysts if they're large enough to cause pressure and pain.
- Bladder or kidney infections. Prompt treatment of infections with antibiotics is necessary to prevent kidney damage.
- Blood in the urine. You'll need to drink lots of fluids, preferably plain water, as soon as you notice blood in your urine to dilute the urine. Dilution might help prevent obstructive clots from forming in your urinary tract.
- Kidney failure. If your kidneys lose their ability to remove waste products and extra fluids from your blood, you'll eventually need either dialysis or a kidney transplant.
- Aneurysms. If you have polycystic kidney disease and a family history of ruptured brain (intracranial) aneurysms, your doctor may recommend regular screening for intracranial aneurysms.
If an aneurysm is discovered, surgical clipping of the aneurysm to reduce the risk of bleeding may be an option, depending on its size. Nonsurgical treatment of small aneurysms may involve controlling high blood pressure and high blood cholesterol, as well as quitting smoking.

Estrategias de afrontamiento y apoyo
Al igual que sucede con otras enfermedades crónicas, tener la enfermedad renal poliquística podría hacerte sentir abrumado. El apoyo de tus amigos y de tu familia es importante para lidiar con una enfermedad crónica. Además, un asesor, un psicólogo, un psiquiatra o un miembro de la Iglesia pueden ayudarte.
También podrías considerar unirte a un grupo de apoyo. Aunque no son para todos, los grupos de apoyo pueden brindar información útil acerca de tratamientos y estrategias de afrontamiento. Además, estar con personas que entiendan lo que estás atravesando podría hacerte sentir menos solo.
Pídele al médico información acerca de los grupos de apoyo de tu comunidad.
Preparación para la consulta
You're likely to start by seeing your primary care provider. However, you might be referred to a doctor who specializes in kidney health (nephrologist).
Here's some information to help you get ready for your appointment.
What you can do
When you make the appointment, ask if there's anything you need to do in advance, such as fasting before having a specific test. Make a list of:
- Your symptoms, including any that seem unrelated to the reason for which you scheduled the appointment, and when they began
- All medications, vitamins and other supplements you take, including dosages
- Your and your family's medical history, particularly kidney diseases
- Questions to ask your doctor
Take a family member or friend along, if possible, to help you remember the information you receive.
For polycystic kidney disease, questions to ask your doctor include:
- What's the most likely cause of my symptoms?
- Are there other possible causes for my symptoms?
- What tests do I need?
- Is this condition temporary or chronic?
- What's the best course of action?
- What alternatives are there to the approach you're suggesting?
- I have other health conditions. How can I best manage them together?
- Do I need to restrict my diet or activities?
- Are there brochures or other printed material that I can take? What websites do you recommend?
Don't hesitate to ask other questions.
What to expect from your doctor
Your doctor is likely to ask you questions, such as:
- Have your symptoms been continuous or occasional?
- Does anything seem to improve or worsen your symptoms?
- Do you know what your blood pressure normally is?
- Has your kidney function been measured?
