🦆 Preputial Blockage (Phimosis/Paraphimosis) in Ducks: A Vet’s 2025 Guide by Dr Duncan Houston BVSc 🩺

By Dr Duncan Houston BVSc – Preputial blockage, including phimosis (narrowing) and paraphimosis (inability to retract), is a serious reproductive concern in drakes. This in-depth 2025 guide covers anatomy, causes, clinical signs, diagnostic workflows, relief techniques (manual, medical, surgical), hygiene protocols, and preventive measures to support your duck’s reproductive health with confidence and compassion. 🚀

📘 Understanding Duck Male Anatomy

Ducks have an internal phallus encased within a preputial sheath when not in mating position. Healthy function relies on clear preputial opening, balanced environment, and brief extension during courtship. Understanding this delicate anatomy helps us recognize and treat blockages effectively.

⚠️ Causes & Risk Factors

• ⚙️ **Trauma or injury** – overzealous female during copulation, collision, or rough surfaces causing sheath tears.
• 🦠 **Infection or inflammation** – bacterial or fungal involvement can obstruct or narrow the opening.
• 📦 **Debris/gunk accumulation** – bedding, mud, feces mixing with natural secretions can create a plug.
• 📉 **Congenital narrowing (phimosis)** – birth defects limiting natural opening flexibility.
• 📦 **Post-mating swelling/paraphimosis** – inability to retract the phallus may lead to edema or ischemia.

👀 Who Is at Risk?

• 🔁 Actively breeding drakes undergoing frequent intromission.
• 🪨 Ducks in unhygienic or abrasive environments.
• 🚼 Young drakes with undeveloped or narrow urethral openings.
• 💧 Overweight birds prone to preputial folds and moisture retention.

🩺 Signs & Symptoms to Watch

• ❌ Visible phallus that remains exposed—**paraphimosis**.
• 🚫 Ducks visibly straining during mounting or excreting.
• 🔴 Swelling, redness, or ulceration around preputial sheath.
• 😕 Discomfort when perineal area is palpated.
• 🔍 Discharge (pus, blood, whitish debris), foul odor signaling infection.
• ⚠️ Secondary signs—lethargy, inappetence, waning fertility.

🔬 Veterinary Diagnostic Approach

• 💡 **Examination** – carefully cleaning and visualizing the sheath and phallus for debris, swelling, or constriction.
• 💧 **Sample collection** – swabs for cytology & culture to detect bacteria or fungi.
• 🩻 **Imaging** – ultrasound may detect fluid-filled swelling or tissue necrosis beneath sheath.
• 🩺 **Bloodwork** – CBC, biochemistry to rule out systemic infection or inflammation.

💪 Relief Options in 2025

1. Manual & Medical Intervention

• 💦 Gently clean and lubricate (sterile water/saline then sterile ointment) to retract phallus and flush debris.
• ✋ If manually retrievable—apply warm compresses for 10–20 min to reduce swelling before traction.
• 💊 Systemic antibiotics and anti-inflammatories based on culture results.

2. Surgical Management

• ✂️ **Sheath incision** under anesthesia to relieve phimosis or severe stricture, followed by suturing or stenting.
• 🧼 Removal of necrotic or infected tissue, clot excision.
• 📥 Placement of temporary stents or foley catheters to maintain sheath patency.

3. Supportive Care Post-Relief

• 🛏 Keep ducks in clean, soft-bedded pens to prevent recurrence.
• 💧 Oral/IV fluids if systemic signs are present.
• 📅 Monitor sheath health—clean 2–3× a day with mild antiseptics.
• 🔁 Continue medications (ABs, NSAIDs) for 7–14 days or as prescribed.
• ⚠️ Stop breeding temporarily until healing completes.

🏠 Home Care & Monitoring

• 🧽 Maintain strict cleanliness—change bedding frequently.
• 🔍 Observe sheath retraction and phallus once or twice daily.
• 🥣 Keep duck calm—limit social or mating behaviors until full recovery.
• 🔬 Record sheath appearance, discharge, swelling—report changes promptly.

🛡️ Prevention & Long-Term Care

• ✔️ Provide soft, dry bedding (straw, hemp pellets) to reduce debris entry.
• ⚖️ Maintain healthy body condition to reduce perineal fat folds.
• 💧 House breeding ducks individually briefly around mating to allow sheath maintenance.
• 📅 Conduct regular checkups around breeding season—inspect sheath visually.
• 🧪 Minimize trauma—avoid rough surfaces, ensure mating pens allow easy footing.
