Overview

Youssef’s syndrome (also called vesicouterine fistula) is a rare abnormal communication between the bladder and the uterus. It is most commonly seen after a cesarean section, but can also follow other pelvic surgeries, traumatic injuries, or severe infections.

Although the exact worldwide prevalence is difficult to determine because many cases are mis‑diagnosed, estimates from tertiary referral centers suggest an incidence of 0.1–0.5 % of all cesarean deliveries in developing countries and up to 2 % in regions with high rates of repeat cesareans.1,2 Women of reproductive age (20–40 years) are the primary group affected, with a slight predominance in primiparous women who have had a low transverse cesarean incision.

Symptoms

The clinical picture varies depending on the size and location of the fistula. The classic triad – known as “Youssef’s triad” – includes:

  • Menouria – cyclic passage of menstrual blood through the urethra (often mistaken for urinary tract infection).
  • Absence of vaginal bleeding – because menstrual blood diverts into the bladder.
  • Urinary continence – unlike most urinary fistulas, patients usually retain normal continence.

Additional symptoms may include:

Urinary symptoms

  • Frequent urge to void during menses.
  • Hematuria that occurs cyclically (often coincident with the first days of the menstrual period).
  • Recurrent urinary tract infections (UTIs) due to bacterial colonisation from menstrual blood.

Gynecologic symptoms

  • Secondary amenorrhea or markedly reduced vaginal bleeding.
  • Pelvic discomfort or a sense of fullness during menses.
  • Infertility or difficulty conceiving after the fistula forms.

Other possible presentations

  • Foul odor from urine during menses.
  • Lower abdominal or suprapubic pain.
  • Psychological distress related to abnormal bleeding patterns.

Causes and Risk Factors

Youssef’s syndrome is an acquired condition. The most common precipitating events are:

  • Cesarean delivery (especially low transverse or classical incisions). The bladder is often dissected from the uterus during the procedure, creating a potential track for a fistula.
  • Instrumental uterine surgery – e.g., myomectomy, dilation & curettage (D&C), hysteroscopic procedures.
  • Pelvic trauma – blunt or penetrating injuries to the lower abdomen.
  • Severe pelvic infection – postpartum endometritis, tuberculous salpingitis, or abscesses that erode adjacent tissues.
  • Radiation therapy to the pelvis for malignancy, which can cause delayed tissue necrosis.

Risk factors that increase the likelihood of a fistula after surgery

  • Multiple prior cesarean sections (scar tissue weakens the uterine wall).
  • Intra‑operative bladder injury that is not recognized immediately.
  • Prolonged labor before delivery, leading to over‑distended uterus.
  • Maternal obesity – makes surgical dissection more challenging.
  • Use of a uterine manipulator or excessive electrocautery near the bladder.

Diagnosis

Accurate diagnosis hinges on a high index of suspicion, especially when a woman presents with cyclic hematuria and reduced vaginal bleeding after a recent obstetric or gynecologic procedure.

Initial assessment

  • Detailed history – timing of symptoms relative to surgery, menstrual pattern, urinary symptoms.
  • Physical examination – pelvic exam may reveal a normal‑appearing cervix; speculum exam typically shows no active vaginal bleeding during menses.

Imaging and diagnostic tests

  1. Ultrasound (transabdominal & transvaginal) – can detect fluid between bladder and uterus and may show a hypoechoic tract.
  2. CT cystography – the gold standard. After filling the bladder with contrast, CT images reveal contrast leaking into the uterine cavity.
  3. MRI pelvis – provides excellent soft‑tissue detail, especially useful when radiation exposure is a concern.
  4. Cystoscopy – direct visualization of the bladder mucosa; a small opening may be seen at the posterior bladder wall, often with menstrual blood flowing out.
  5. Hysterosalpingography (HSG) – contrast injected into the uterine cavity; leakage into the bladder confirms the fistula.

Laboratory work

  • Urine analysis & culture – to assess for secondary infection.
  • Complete blood count – to check for anemia secondary to chronic blood loss.

Treatment Options

Management aims to close the fistulous tract, restore normal urinary and menstrual function, and prevent recurrence. The choice of therapy depends on fistula size, location, patient’s desire for future fertility, and overall health.

Conservative measures (small fistulas)

  • Bladder catheterization – continuous drainage for 2–4 weeks can allow a tiny (<5 mm) fistula to close spontaneously.
  • Hormonal suppression – combined oral contraceptives or GnRH analogues to suppress menses, reducing the volume of blood passing through the fistula during healing.

Surgical repair

Most patients ultimately require surgery. Techniques include:

  1. Transvesical (via bladder) repair – a lower abdominal incision allows direct access to the fistula; the tract is excised and bladder and uterine walls are closed in separate layers.
  2. Transabdominal (extraperitoneal) repair – preferred for larger defects; includes interposition of healthy tissue (e.g., omentum, peritoneum, or a Martius flap from labial fat) to reinforce the closure.
  3. Laparoscopic or robotic‑assisted repair – minimally invasive, associated with shorter hospital stay and less postoperative pain. Success rates of 85–95 % have been reported in recent series.3
  4. Uterine‑preserving vs. hysterectomy – If the patient desires future fertility, uterine‑preserving repair is attempted. In cases of extensive uterine damage or recurrent fistula, hysterectomy may be the definitive solution.

Post‑operative care

  • Indwelling Foley catheter for 7–14 days to keep the bladder decompressed.
  • Broad‑spectrum antibiotics for 24‑48 hours to prevent infection.
  • Analgesia and early ambulation.
  • Follow‑up imaging (cystography or MRI) at 6–8 weeks to confirm closure.

Adjunct therapies

  • **Hyperbaric oxygen therapy** – experimental, may promote tissue healing in refractory fistulas.
  • **Stem‑cell‑enriched grafts** – under investigation for complex, radiation‑induced fistulas.

Living with Youssef’s Syndrome

Even after successful repair, patients may need ongoing strategies to manage symptoms and prevent recurrence.

Daily management tips

  • Hydration – drink at least 2 L of water daily to keep urine dilute and reduce infection risk.
  • Bladder training – scheduled voiding every 3–4 hours helps maintain low bladder pressure.
  • Hygiene – wipe front-to‑back, change pads promptly during menses, and consider using a menstrual cup only after confirmed fistula closure.
  • Pelvic floor exercises – strengthen the sphincter complex; Kegel exercises can improve continence confidence.
  • Follow‑up appointments – keep all urology/gynecology visits; annual pelvic ultrasound is often recommended.

Psychosocial aspects

Menstrual blood in urine can be frightening and socially embarrassing. Encourage patients to:

  • Seek counseling or support groups (e.g., obstetric fistula NGOs).
  • Discuss concerns with partners and close family to reduce isolation.
  • Document episodes (color, volume, timing) to share with healthcare providers.

Prevention

Because most cases are iatrogenic, prevention centers on safe obstetric and surgical practices.

For clinicians

  • Meticulous bladder identification and protection during cesarean sections.
  • Immediate intra‑operative repair of any bladder injury.
  • Limit use of electrocautery near the posterior bladder wall.
  • Administer prophylactic antibiotics per guidelines to reduce postoperative infection.

For patients

  • Attend prenatal classes that discuss risks of multiple cesarean deliveries.
  • Ask obstetricians about alternative delivery options when medically feasible.
  • Report any abnormal urinary symptoms promptly after surgery.

Complications

If left untreated, a vesicouterine fistula can lead to several serious sequelae:

  • Chronic anemia from ongoing blood loss into the bladder.
  • Recurrent UTIs – may progress to pyelonephritis or sepsis.
  • Infertility – due to altered uterine environment and scarring.
  • Poor quality of life – mental health impact, social stigma.
  • Renal impairment in rare cases where obstructive uropathy develops.

When to Seek Emergency Care

Call 911 or go to the nearest emergency department if you experience any of the following:
  • Sudden inability to urinate (urinary retention) accompanied by severe lower‑abdominal pain.
  • Fever > 38.5 °C (101.3 °F) with chills, indicating a possible severe urinary infection or sepsis.
  • Heavy vaginal bleeding or massive hematuria that soaks through pads in less than an hour.
  • Sudden, sharp pelvic pain after a recent pelvic procedure.

Prompt treatment can prevent life‑threatening complications.
