Episioplasty / Vulvoplasty

Episioplasty (vulvoplasty) corrects a recessed or hooded vulva in female dogs — resolving the skin fold that traps moisture and bacteria, causing recurrent urinary tract infections and dermatitis.

An episioplasty, also called a vulvoplasty or perivulvar skin fold resection, is a surgical procedure that removes the excess skin fold surrounding a recessed (hypoplastic or juvenile) vulva. In affected dogs, the vulva sits recessed beneath an overhanging fold of perineal skin rather than being normally prominent. That fold traps moisture, urine, and bacteria against the sensitive tissues of the vulva and vaginal opening, creating a warm, moist environment where infections thrive. The result is a cycle of chronic urinary tract infections (UTIs), skin redness, odor, and discomfort that is frustratingly resistant to antibiotic treatment alone. Episioplasty removes the redundant fold and repositions the vulva into a more exposed, self-draining position, breaking that cycle permanently. Dr. Alan Schulman, our board-certified surgeon (ACVS), performs this procedure at Dog & Cat Hospital Calabasas.

Why It's Recommended

Episioplasty is recommended when a recessed vulva is the confirmed anatomical driver of recurrent or persistent urinary and skin problems. Indicators that surgery is appropriate include:

  • Three or more UTIs within a twelve-month period despite appropriate antibiotic treatment based on culture results
  • Chronic perivulvar (around-the-vulva) dermatitis — redness, discharge, odor, and skin thickening — that returns after topical treatment
  • Vaginal fold pyoderma (skin infection within the fold) that does not resolve with cleaning and medical therapy
  • Urinary incontinence or pooling associated with recessed vulvar conformation

In many young female dogs, the vulva is naturally somewhat recessed before the first heat cycle. Waiting until after one heat cycle or spaying is often recommended, because hormonal changes frequently cause the vulva to mature and the problem to resolve on its own. Surgery is reserved for dogs whose anatomy does not normalize with time or hormonal change, or for older spayed dogs in whom the anatomy has never improved.

How the Procedure Works

Episioplasty is performed under general anesthesia with full monitoring. The procedure involves careful removal of the excess perivulvar skin fold:

  • The surgeon designs the skin excision to remove the overhanging fold on one or both sides of the vulva, while preserving enough surrounding tissue to close without tension
  • The skin and underlying subcutaneous tissue of the fold are excised
  • The remaining skin edges are sutured together so the vulva is now exposed and flush with — or slightly prominent from — the surrounding skin
  • The closure is performed in layers using absorbable sutures internally and non-absorbable sutures or staples at the skin surface

If spaying has not yet been performed, the surgical team may discuss doing so concurrently, as the hormonal environment of an intact female can perpetuate recessed vulvar conformation and recurrent infections.

Preparation

Before scheduling episioplasty, the team confirms that the anatomy — not some other cause — is responsible for the recurring infections:

  • Urine culture to document active infection and guide antibiotic therapy prior to surgery
  • Physical examination of the perivulvar region, assessing fold depth, skin condition, and vulvar positioning
  • Vaginal examination to rule out vaginal stricture, vaginitis, or other concurrent pathology contributing to the clinical signs
  • Pre-anesthetic bloodwork appropriate for the patient's age
  • Food withheld the night before; the perivulvar region is clipped and prepared prior to the procedure

Recovery & Aftercare

Recovery from episioplasty is generally smooth. Home care focuses on keeping the incision clean, dry, and protected:

  • Entire healing period (10–14 days): e-collar worn continuously — licking the perineal incision rapidly causes wound breakdown
  • Days 1–7: mild swelling and bruising around the suture line is normal; keeping the area dry and monitoring for discharge
  • Days 1–14: leash walks only; avoid sitting in wet grass or swimming
  • 10–14 days: recheck visit for suture removal and assessment of healing

Antibiotics prescribed for a pre-existing UTI are continued through the recommended course. A urinalysis is rechecked at the post-operative visit to confirm the infection has cleared. Most owners see a dramatic reduction in recurrent infections within the first two to three months after healing.

Risks & What to Expect

Episioplasty is a well-tolerated procedure with a high success rate for reducing recurrent infections. Potential complications include:

  • Wound dehiscence (incision opening) — the most common complication, usually caused by licking; the e-collar must be used consistently throughout healing
  • Seroma (fluid accumulation under the skin) — typically resorbs without intervention
  • Incomplete resolution of infections if there is a concurrent vaginal or bladder abnormality that was not identified pre-operatively

The majority of dogs experience a significant and lasting reduction in UTI frequency and perivulvar dermatitis after episioplasty. Owners who have managed years of repeated infections often describe the improvement as transformative for their dog's comfort and their own quality of life.

Frequently Asked Questions

1My female dog keeps getting urinary tract infections — could her anatomy be the cause?
Yes — a recessed or hooded vulva is a recognized anatomical cause of recurrent UTIs in female dogs. The overhanging skin fold traps moisture and bacteria against the vulva and vaginal opening, making infections persistent despite appropriate antibiotic treatment.
2How do I know if my dog has a recessed vulva?
A recessed vulva sits below the skin surface, obscured by an overhanging fold of perineal skin. When you part the fold, the vulva is not visible at the skin level. Your veterinarian can confirm this on physical examination and assess whether it is contributing to recurring infections.
3Should I wait until after my puppy's first heat before doing episioplasty?
Often yes — the vulva naturally matures and becomes more prominent under the influence of estrogen during the first heat cycle, and the problem sometimes resolves on its own. Many surgeons recommend waiting until after one heat or spaying before evaluating whether surgery is needed.
4Can episioplasty be done at the same time as spaying?
The two procedures can be combined in one anesthetic event, which avoids a second surgery. The surgical team will discuss whether combining them makes sense for your dog's specific situation.
5Will episioplasty completely stop my dog's urinary infections?
Most dogs experience a dramatic reduction in UTI frequency after episioplasty, but it is not a guarantee of zero future infections. The surgery removes the anatomical predisposing factor — it cannot prevent every possible cause of a UTI going forward.
6Is episioplasty painful for dogs?
The procedure is performed under general anesthesia and managed with multi-modal pain control including nerve blocks and systemic pain medication. Most dogs are comfortable within twenty-four to forty-eight hours of surgery.
7How long after surgery before my dog is back to normal?
Most dogs return to normal activity within two to three weeks. The incision heals within ten to fourteen days, at which point sutures are removed and the dog can resume full activity.
8Can cats have recessed vulvas and need episioplasty too?
Recessed vulvar conformation and episioplasty are far more commonly discussed in dogs. It is rarely reported in cats, and recurrent UTIs in female cats are usually attributed to other causes such as urinary tract inflammation or stones.
