Pelvic Bladder (Caudal Bladder Displacement) in Cats: A Vet’s 2025 Guide to Diagnosis, Treatment & Recovery 🐱

Hi! I’m Dr. Duncan Houston BVSc, veterinarian and founder of Ask A Vet. In this 2025 guide, we explore pelvic bladder—a condition where the bladder shifts caudally into the pelvic canal. Though rare, it can cause urinary issues including incontinence, difficulty urinating, infections, and discomfort. We’ll cover underlying causes, diagnostic steps, treatment options, and long-term support for optimal recovery.

📘 1. What Is a Pelvic Bladder?

A pelvic bladder refers to the abnormal positioning of a cat’s urinary bladder into its pelvic canal—rather than its normal location in the abdomen. This displacement can narrow the urethra and interfere with urinary function :contentReference[oaicite:3]{index=3}.

⚠️ 2. Causes & Risk Factors

• Congenital abnormalities—rare birth defects affecting bladder suspension :contentReference[oaicite:4]{index=4}
• Obesity—increased abdominal fat may push the bladder caudally :contentReference[oaicite:5]{index=5}
• Previous surgeries or trauma—scar tissue or pelvic fractures can shift bladder position.
• Chronic straining—from urinary disease like FLUTD, stones, or infections may alter organ placement :contentReference[oaicite:6]{index=6}.

👀 3. Signs & Symptoms

Symptoms vary depending on bladder displacement severity:

• Urinary incontinence—dribbling, leakage, urine scald :contentReference[oaicite:7]{index=7}
• Straining or producing only small amounts of urine :contentReference[oaicite:8]{index=8}
• Frequent trips to the litter box (pollakiuria) :contentReference[oaicite:9]{index=9}
• Blood in urine, tail/base area wetness :contentReference[oaicite:10]{index=10}
• Recurrent urinary tract infections due to abnormal urine flow :contentReference[oaicite:11]{index=11}
• Possible pain or discomfort seen as vocalizing when urinating.

🔍 4. Diagnostic Approach

1. History & physical exam: ask about urinary habits, incontinence, straining, accidents.
2. Palpation/observation: displaced bladder may be felt further caudally near pelvis.
3. Lab tests: CBC, biochemistry to evaluate kidney function, electrolytes; urinalysis and culture to detect infections or crystals :contentReference[oaicite:12]{index=12}.
4. Imaging:
   • X‑rays: may show bladder in pelvic canal.
   • Ultrasound: confirms caudal displacement, evaluates bladder walls, detects stones or structural defects :contentReference[oaicite:13]{index=13}.
5. Optional tests: contrast radiography or CT to detail anatomical abnormalities; cystoscopy for direct bladder examination.

🛠️ 5. Treatment Options

A. Medical Management

• Address underlying issues: treat FLUTD, dissolve stones, antibiotics for infection:contentReference[oaicite:14]{index=14}.
• Supportive care: increased fluid intake (wet food), medications to ease inflammation or spasm.
• Manage weight: dietary changes and exercise to reduce obesity.

B. Surgical Correction

• Surgery may be recommended if displacement causes obstruction, persistent infections, or incontinence.
• Bladder repositioning (cystopexy): bladder is sutured to abdominal wall to restore normal placement.
• Concurrent removal of stones, biopsy of bladder wall, or urethral adjustments if needed.

C. Post‑Treatment Care

• Monitor urination: tracking volume, frequency, accidents using Ask A Vet app.
• Continue bladder health support: wet diet, infection prevention supplements.
• Schedule follow-up imaging to confirm bladder remains in correct position.

📈 6. Prognosis & Monitoring

• Medical management alone may suffice in mild cases with no obstruction.
• Surgery typically yields excellent outcomes for symptomatic cats.
• Monitor for UTIs, straining, or bladder displacement recurrence with recheck scans.
• Long-term bladder health and weight normalization key to maintaining resolution.

🏡 7. Home Care Essentials

• Use wet food and ensure fresh water at several points in the home.
• Keep litter box clean and easily accessible.
• Watch for signs of infection, incontinence, straining; log observations via the app.
• Maintain a healthy body condition and pelvic health after surgery (if performed).

📚 8. Example Case

“Bella,” a 5‑year‑old indoor spayed DSH, presented with urine dribbling and frequent trips but minimal urine passed. Ultrasound showed bladder located low in pelvis with evidence of thickened bladder wall. Transitioned to wet diet, infection treated, weight reduced. Later developed recurrence and underwent cystopexy. Post-op she urinated normally, regained control, and remained symptom-free at one-year follow-up, confirmed by ultrasound.

🚨 9. When to Contact the Vet Immediately

• Complete urinary blockage or straining without output
• Visible blood in urine or blood near tail area
• Recurring or untreated urinary tract infections
• Signs of discomfort or pain while urinating

✨ 10. Final Thoughts

Pelvic bladder displacement in cats, though uncommon, can lead to serious urinary issues. Early detection through history, exams, and imaging—paired with targeted medical or surgical care—can restore bladder position and function. Long‑term management of bladder health, infection control, and body condition supports lasting recovery.
