Crested Gecko Prolapse: What a Cloacal or Hemipenal Prolapse Looks Like & What to Do

A prolapse means tissue from inside the vent has pushed outside and cannot stay where it belongs. In reptiles, the prolapsed structure may be cloaca, colon, oviduct, bladder, or in male lizards, a hemipenis. Merck notes that common causes of vent prolapse in reptiles include dystocia or egg-related problems, breeding trauma, cloacal inflammation or infection, metabolic disease, bladder stones, kidney disease, cancer, and other space-occupying masses that make the animal strain to pass stool or urates.

In crested geckos, straining is often the practical clue. That straining may come from constipation, dehydration, intestinal irritation, parasites, cloacitis, retained eggs in females, or reproductive activity in males. PetMD also lists cloacal prolapse as a possible sign of metabolic bone disease in reptiles, which matters because poor calcium balance and husbandry problems can weaken normal muscle function and overall body condition.

Hemipenal prolapse is a little different from a cloacal prolapse. In a male gecko, one or both hemipenes may remain outside the vent after breeding behavior, irritation, trauma, or swelling. Merck notes that a prolapsed hemipenis can sometimes be reduced after swelling is decreased, but if the tissue is too damaged or repeatedly prolapses, surgical amputation may be an option because hemipenes are used for reproduction rather than urination.

The visible tissue does not tell you the whole story. The real problem is often the reason your gecko strained in the first place, so your vet will usually focus on both replacing or protecting the tissue and finding the underlying cause.

See your vet immediately if you notice any pink, red, purple, or dark tissue protruding from the vent. This is especially urgent if the tissue is drying out, getting darker, bleeding, contaminated with substrate, or if your gecko is repeatedly straining. Reptile prolapse is time-sensitive because exposed tissue can swell and lose blood supply, making reduction harder and increasing the chance of permanent damage.

There is very little true "monitor at home" time with a prolapse. Home care is supportive while you arrange veterinary treatment, not a substitute for it. If the tissue slips out briefly and retracts on its own, your gecko still needs prompt veterinary follow-up because recurrence is common and the cause still needs to be addressed.

Go to the nearest exotic-capable urgent care or emergency hospital the same day if your gecko seems weak, cold, painful, dehydrated, cannot pass stool or urates, has a swollen abdomen, may be egg-bound, or the tissue has been out for more than a short period. If you do not have immediate access to an exotics vet, call the closest emergency hospital and ask whether they can stabilize a reptile while helping you transfer care.

Do not try to pull on the tissue, trim it, apply powders, use hemorrhoid creams, or force-feed. Those steps can worsen trauma or delay the care your gecko needs.

Your vet will first identify what organ has prolapsed, because treatment depends on the tissue involved. Merck emphasizes that this distinction matters: cloaca, colon, bladder, and oviduct generally need to be preserved and replaced if viable, while a severely damaged prolapsed hemipenis may sometimes be amputated. Your vet will assess color, swelling, contamination, and whether the tissue still appears alive.

Initial treatment often includes gentle cleaning, lubrication, and measures to reduce swelling. Merck notes that concentrated sugar or salt solutions may be used topically to shrink edematous tissue before replacement. Depending on your gecko's stress level and the severity of the prolapse, your vet may use sedation or anesthesia to safely reduce the tissue and minimize further straining.

After reduction, your vet may place a temporary retaining suture around the vent in selected cases, prescribe medications based on the cause, and recommend diagnostics such as a fecal test, radiographs, or bloodwork when appropriate. Those tests help look for parasites, egg retention, metabolic disease, stones, infection, or other causes of abdominal pressure and straining.

If the tissue is badly damaged, repeatedly prolapses, or cannot be replaced safely, surgery may be needed. Prognosis is often good when treatment happens early and the underlying cause is corrected, but delayed care raises the risk of necrosis, infection, recurrence, and more invasive procedures.

Home care starts while you are arranging urgent veterinary treatment. Move your gecko to a clean, simple hospital enclosure lined with damp paper towels instead of loose substrate so debris does not stick to the tissue. Keep the prolapsed tissue moist with sterile saline or a plain water-based lubricant. If neither is available right away, clean lukewarm water is better than letting the tissue dry out.

Handle as little as possible. Stress and struggling can increase straining and swelling. Keep the enclosure in the species-appropriate temperature range recommended by your vet, and avoid overheating. Do not soak the gecko deeply, do not use sugar pastes unless your vet specifically instructs you to, and do not try to push the tissue back in yourself unless you are being directly guided by a veterinarian.

After treatment, your vet may recommend temporary paper towel substrate, extra hygiene, medication, and close monitoring of stool, urates, appetite, and activity. Follow those instructions closely. Recovery is not only about the visible tissue. It is also about correcting the reason the prolapse happened, whether that is husbandry, parasites, constipation, reproductive disease, or another medical problem.

If the tissue comes back out, darkens, bleeds, smells foul, or your gecko stops passing stool or urates, see your vet again immediately.
