Can polycystic kidney disease be cured?

Polycystic kidney disease generally cannot be fully cured. Treatment focuses on managing complications, slowing the decline in kidney function, and improving quality of life. Follow your vet's specific recommendations.

What imaging tests are needed when cysts are found?

Ultrasound is the first-line choice for assessing cyst location and size; X-ray or CT may be arranged for further structural evaluation when needed. Follow your vet's recommendations based on available equipment.

How often should kidney function be monitored?

Follow-up frequency varies with the pet's condition and test results. Blood and urine checks every 3–6 months are common, but follow your vet's specific schedule.

What should I do if I notice blood in the urine or difficulty urinating?

If you notice blood in the urine or difficulty urinating, seek veterinary assessment promptly. The vet will use tests to identify the cause and decide on next steps.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek emergency care immediately

•Completely unable to urinate or straining without producing urine for more than six hours
•Urine is persistently bright red or contains blood clots
•Sudden extreme weakness or collapse within a short period of time

Schedule a clinic visit soon (within 24–72 hours)

•Abdomen is progressively and noticeably distended or bloated, with discomfort when touched
•Pet flinches or cries out when the abdomen is touched
•Significant and persistent change in water intake or urine output

01What symptoms indicate a problem?

Polycystic kidney disease often causes abdominal distension, pain, and changes in elimination as cysts in the kidney or abdominal cavity enlarge; early stages may show no obvious symptoms.

Noticeable abdominal swelling or localized bloating, with a palpable abnormal mass
Flinching, crying out, or showing discomfort when the abdomen or flank is touched
Decreased appetite, reduced activity, or changes in alertness
Changes in urination frequency or volume, abnormal urine colour, or difficulty urinating
Noticeable weight loss or fluctuation over a short period

Seek emergency care immediately if you notice the following symptoms:

⚠️ Unable to urinate for an extended period
⚠️ Bright red urine or visible blood clots in urine
⚠️ Sudden extreme weakness or collapse

02How to assess abnormalities at home: key observations and when to seek emergency care

Keeping a home record of changes helps the vet assess disease progression and plan tests; videos or photos can support the diagnosis when needed.

Observe and record daily changes in alertness and activity level
Weigh your pet daily and log changes to track short-term trends
Estimate and record your pet's daily water intake
Observe and record urination frequency, volume, and urine colour
Note whether appetite or food intake has decreased or changed
Film abnormal urination or abdominal appearance to assist the vet during the visit

03How does the vet make a diagnosis? Common diagnostic tests

The vet will combine a physical examination, blood and urine tests, and imaging to assess how the cysts are affecting kidney function and overall health.

Physical examination

abdominal palpation to assess masses, pain response, and hydration status

Blood and biochemistry panel

evaluates kidney function, electrolytes, and other organ health

Urinalysis and bacterial culture

checks for blood in urine, infection, or proteinuria

Ultrasound

primarily used to confirm cyst location, size, and kidney structure

X-ray or CT scan

evaluates overall abdominal structure or more complex anatomical findings

04How to treat and care for your pet after diagnosis: medications, diet adjustments, and care guide

Treatment depends on test results and may include managing infections, supportive care, and long-term monitoring with regular tests to track kidney function.

If infection or complications are present, the vet will treat them based on test results
Feed a veterinary renal diet and ensure adequate hydration and electrolyte management
Restrict strenuous activity at home, administer medications on schedule, and watch for side effects
Attend regular follow-up appointments to monitor blood, biochemistry, and urine test results
Record medication responses and any changes in condition; report abnormalities to the vet promptly
Referral to a specialist centre with advanced imaging or nephrology expertise may be recommended

05What to prepare before the vet visit: key information to help the vet quickly identify the cause

Bring videos or photos of abnormal urination or abdominal appearance for the vet to review

Record urine colour, presence of blood in urine, urine volume, and estimated urination frequency

Note when symptoms first appeared and how they have progressed

Bring previous test reports, imaging results, and a current medication list

Log daily water intake, appetite, and weight changes

Book an appointment at a clinic equipped for blood tests and imaging, or a specialist practice
