  Abstract 


We present two cases of congenital vaginal agenesis with functional uterine corpus, manifesting with periodic lower abdominal pain and hematometra in adolescence. Both patients were successfully treated with the creation of neovagina and neocanal structures to discharge menstrual blood; this may also facilitate the preservation of fertility. Both cases were characterized by degrees of congenital vaginal agenesis, whether short or completely absent, with no communication between the uterine cavity and external genitalia, as confirmed by physical examination and imaging. We surgically reconstructed a neovagina with the modified McIndoe's procedure, using an artificial skin graft, and canalized to the caudal portion of the uterine cavity. Although redilatation of the neocanal was required, no patient suffered severe infection in postoperative course and both now exhibit regular menstruation. Although hysterectomy has classically been the preferred treatment for such cases, recent technical progression enables treatment of such diseases with conservative and minimally invasive surgery, in a safe manner.

  Introduction Top


Congenital vaginal agenesis occurs in 1 in 4000–10,500 live female births, among which normal development of the uterine corpus is observed in <10% of patients.[1] In such cases, surgical intervention should be performed in adolescence for drainage of menstrual blood, to relieve pelvic pain and to avoid retrograde menstruation, which may result in endometriosis and infertility in the future. Historically, hysterectomy has been the chosen procedure to relieve symptoms through obstruction of menstrual blood flow and to avoid severe postoperative complications such as pelvic inflammatory disease.[2],[3],[4] However, recent progressions in surgical techniques and devices have made it possible to not only treat symptoms but also to provide an avenue to preserve fertility.[1],[3],[5] Here, we present two cases of congenital vaginal agenesis with functional uterine corpus, successfully treated without hysterectomy.


  Case Reports Top


Case 1

A 14-year-old virgin girl was referred to our hospital with primary amenorrhea and a 1-year history of cyclic lower abdominal pain. A 1-cm blind vagina was present on physical examination. The transrectal ultrasonography revealed a 4.7 cm × 3.5 cm-sized central fluid pooling in the uterus. A 1.5 cm-sized hypoechoic mass in the left ovary was also noted. The drip infusion pyelography (DIP) was normal. The pelvic magnetic resonance imaging (MRI) revealed clotted blood filling the uterine cavity and a 1.5 cm-sized chocolate cyst in the left ovary. However, the uterine cervix was absent [Figure 1]a and [Figure 1]b.

A diagnosis of congenital cervicovaginal agenesis was established, with the first operation performed to drain fluid pooled in the uterine cavity as a means of relieving the lower abdominal pain. After monthly intramuscular administration of 1.88-mg depot leuprolide acetate, the second vaginoplasty operation, involving canalization from the uterine body to the vagina, and cystectomy of the left ovary, were performed. In laparotomy, we observed a normal uterine corpus; however, the uterine cervix was not apparent. The neovagina was created with the modified McIndoe's procedure, using an artificial skin graft (Terudermis®). A reverse T incision was made in the inferior part of the uterine body, and canalization between the lower part of the uterus and the upper vault of the neovagina was performed using forceps. A balloon catheter was inserted to maintain patency [Figure 1]c.

Postoperative course

The patient ran a fever 5 days after the operation. On the 7th postoperative day (POD), the balloon catheter and prosthesis were removed in an attempt to mitigate a fever that had not settled in spite of antibiotics administration. After the body temperature had normalized, a Nelaton catheter (22 Fr) was reintroduced to the neocanal. On the 20th POD, the Nelaton catheter spontaneously fell off and the canal was obstructed. Recanalization under ultrasound guidance was performed, and a urethral catheter (14 Fr) was inserted. Following catheter removal, cervical dilatation with Hegars cervical dilator was performed to avoid reobstruction, on every visit to the outpatient clinic. At the time of writing, 6 years after surgery, menstruation is normal, without cervical dilation or recurrent hematometra.

Case 2

A 14-year-old virgin girl was referred to our hospital with a 2-year history of cyclic lower abdominal pain, loss of consciousness, and primary amenorrhea. During the physical examination, we observed an absent vagina. Transrectal ultrasound scan showed that the uterus was 7.4 cm in length with a small amount of central fluid at the uterine cervical portion. A hypoechoic mass of 8 cm in diameter was found in the left ovary. The right ovary was normal. DIP exhibited incomplete duplication of the right ureter. The pelvic MRI revealed clotted blood filling the uterine cervical portion and an 8 cm-sized chocolate cyst in the left ovary [Figure 2]a and [Figure 2]b. On the other hand, the uterine corpus was not filled with the clotted blood. It seemed that it was pooling in the upper part of the vagina and that the overt uterine cervical structure was absent. She was diagnosed with high vaginal atresia with cervical hypoplasia.

Laparoscope-assisted surgery was performed. During the operation, we found a small, hen egg-sized uterine body and an enlarged uterine cervical portion/upper vagina. An 8cm-sized chocolate cyst and hematosalpinx were also observed in the left adnexa. The right ovary was normal. Left ovarian cystectomy and left salpingectomy were performed. The peritoneum of the vesicouterine pouch was opened and the uterine cervical portion/upper vagina was incised vertically. Chocolate-like fluid was extracted [Figure 2]c. A horizontal incision was made on the vaginal vestibule. A neovagina was constructed with the same procedure as used in Case 1 [Figure 2]e. The functional uterus and the upper vault of the neovagina were penetrated using forceps, inserted through the incision in the uterine cervical portion/upper vagina [Figure 2]d. The canal was then dilated to insert a 10-Fr Nelaton catheter to maintain patency.

Postoperative course

The neovagina was washed daily to prevent infection. On the 9th POD, the Nelaton catheter and prosthesis were removed. The patient was able to put on and take off a prosthesis by herself, every day. On the 60th POD, the neovagina was restenosed. We performed vaginal expansion with a cusco-type speculum, involving recanalization under transabdominal ultrasound guidance, and balloon catheter replacement. Current menstrual status is normal; however, a balloon catheter and prosthesis are still required.


  Discussion Top


The prevalence of Müllerian anomalies is ~4% in the general population.[4] Among them, congenital vaginal agenesis with functional uterus is a rare disease entity. The Müllerian malformation manifests with various phenotypes due to the variance of developmental defects in the female genitourinary tract.[6] Both cervicovaginal agenesis and vaginal agenesis/cervical atresia are thought to originate with developmental defects of the Müllerian tubercle.[6] According to the Müllerian development anomaly classification of the American Fertility Society (AFS), both our cases are classified as Class 1A (Class 1 includes all cases of vaginal agenesis/hypoplasia)[7] because the AFS classification fails to distinguish between cervicovaginal agenesis and vaginal agenesis/cervical atresia. Recently, newly designed classifications have been proposed. The European Society of Human Reproduction and Embryology and the European Society for Gynecological Endoscopy have presented a new classification based on the anatomy of the uterus, cervix, and vagina.[8] According to this, both our cases are classified as a class U0/C4/V4.

The major postoperative complication in vaginal agenesis/cervical atresia is infection and stenosis of the neocanal,[1] with both of our patients exhibiting some degree of infection. Many of these cases required catheters to maintain patency of the neocanal;[1],[3],[4],[9],[10],[11] however, long-term use of a foreign body is associated with development of infectious disease. Some patients, following uterovaginal canalization, required hysterectomy for pelvic inflammatory disease in the literature and even death by sepsis has been reported.[4] Therefore, one of the key points in postoperative management is the judgment of an adequate indwelling period for a neocanal catheter to maintain patency while simultaneously protecting patients from infection. In our cases, canalization between the uterus and the neovagina was made by blunt penetration using forceps. Acién et al. recommends anastomosing the uterine body into the created neovagina after resecting the cervical fibrous tract.[1],[5] Although their reported case needed reoperation for recanalization because of stenosis, the patency of the neocanal maintained, resulting in spontaneuous gestation after the third operation.[1] Deffarges et al. also reported that uterovaginal anastomosis appears to be an adequate treatment of uterine cervical atresia with good functional results, by analyzing their experienced cases.[3]

We performed vaginoplasty through the modified McIndoe's procedure using an artificial skin graft. Our results suggest that this methodology limits postoperative scarring and vaginal stricture, while simultaneously being a relatively straightforward technique. The skin,[1],[11] bladder mucosa,[12] or amniotic membrane[13] were used as graft media in the literature. On the other hand, Ghafarnejad et al. observed effective results in vaginoplasty using no graft, with good postoperative results.[10]

With the spread of laparoscopic techniques, reports describing laparoscope-assisted surgery in cases of vaginal agenesis/cervical atresia are increasing.[9],[11],[14] Laparoscope-assisted surgery is less invasive and is considered especially suitable for young women, due to reduced likelihood for intraperitoneal adhesions following surgery, which may contribute to fertility potential in the future.

We present two cases of congenital agenesis of vagina with functional uterine corpus. We successfully treated these cases with vaginoplasty and the canalization between the neovagina and the uterine corpus, making it possible to discharge menstrual blood and hopefully facilitating preservation of fertility. While the patients did exhibit some complications in postoperative course, such as infection and restenosis, conservative surgery could be achieved with comparable safety.
