Difference in reproductive performance between two subtypes of bicornuate uterus

PURPOSE

We compared reproductive outcome in patients with two subtypes of bicornuate uterus who underwent a Strassmann metroplasty procedure.

METHODS

Eleven patients diagnosed using the R-AFS definition were divided into partial and complete type, then reproductive outcome following a Strassmann metroplasty was evaluated.

RESULTS

All four patients with the partial type anomaly conceived and achieved a live birth, while none of the seven with the complete type anomaly were able to conceive.

CONCLUSION

Patients with the partial type of bicornuate uterus showed a favorable prognosis after a Strassmann metroplasty. Conversely, those with the complete type should be treated as uterus didelphis, and not undergo a metroplasty.

Does surgery improve live birth rates in patients with recurrent miscarriage caused by uterine anomalies?

We found that congenital uterine anomalies have a negative impact on reproductive outcome in recurrent-miscarriage couples, being associated with further miscarriage with a normal embryonic karyotype. There has been no study comparing live birth rates between patients with and without surgery. We conducted a prospective study to prove that surgery for a bicornuate or septate uterus might improve the live birth rate. A total of 170 patients with congenital uterine anomalies suffering two or more miscarriages were examined. The live birth rate after ascertainment of anomalies, cumulative live birth rate and infertility rate, were compared between patients with and without surgery. In patients with a septate uterus, the live birth rate (81.3%) at the first pregnancy after ascertainment of anomalies with surgery tended to be higher than that (61.5%) in those without surgery. The infertility rates were similar in both groups, while the cumulative live birth rate (76.1%) tended to be higher than without surgery (60.0%). Surgery showed no benefit in patients with a bicornuate uterus for having a baby, but tended to decrease the preterm birth rate and the low birth weight. The possibility that surgery has benefits for having a baby in patients with a septate uterus suffering recurrent miscarriage could not be excluded.

Reproductive Outcome after Hysteroscopic Metroplasty in Patients with Infertility and Recurrent Pregnancy Loss

Introduction: Reproductive outcome can be negatively affected in patients with congenital uterine anomalies (CUA), increasing the number of unsuccessful pregnancies and obstetric complications. Compared with the population with normally formed uterus, patients with CUA have higher abortion rate, higher fetal loss rate and decreased live birth rate. Hysteroscopic metroplasty (HM) is a standard, safe and minimally invasive method for the treatment of correctible types of congenital uterine anomalies.Aim: The aim of the study was to analyze the reproductive outcome in group of patients with infertility and recurrent pregnancy loss and present CUA, before and after hysteroscopic metroplasty.Material and Methods: We analyzed 67 patients to whom 78 interventions hysteroscopic metroplasty were performed at the University Clinic of Obstetrics and Gynecology in Skopje during a two year period, between 01.01.2010 and 31.12.2011. Their reproductive outcome was monitored during a two-year period and the same group served as a control group, taking into account their previous reproductive history. Statistical analysis was performed using Chi-square test and p < 0.05 was considered to be statistically significant.Results: Most common CUA were types 5b and 6 represented by 88 %. In a follow up period of two years, 33 of the patients become pregnant. There was a statistically significant decrease of abortion rate from 92% to 21.2%, as well as an increase in the term delivery rate from 0% to 69.7%.Conclusion: Treatment with hysteroscopic metroplasty is significantly improving the reproductive outcome in patients with CUA and previous fetal loss.

Frequency of Uterine Malformations Among Women in a Restricted Gene Pool Community

This random, retrospective cross-sectional study was performed to determine the frequency of uterine malformation in restricted gene pool communities. During 2003—2006, 800 women from the community of LaCrete in northern Alberta, Canada (known restricted gene pool for over 500 years), participated. Of the participants, 156 (19.5% of the study population) showed some form of structural uterine malformation. This is 5.5 times higher than what is reported in the general population. All 156 subjects were further investigated with magnetic resonance imaging, 3D sonography, hysterosalpingiography, hysteroscopy, and laparoscopy. These tests revealed that 30 of these women had no previous pregnancies or live births, 40 had one or more previous pregnancies and live births and more than two miscarriages, and 55 had recurrent miscarriages. This study has provided new insights into the increasing number of uterine malformations in the LaCrete population. The significantly higher prevalence of uterine malformations in a restricted gene pool community compared to the reported prevalence in the general population might indicate a direct link between a lack of genetic diversity and the development of uterine malformations in women.

Small-diameter hysteroscopy with Versapoint versus resectoscopy with a unipolar knife for the treatment of septate uterus: A prospective randomized study

STUDY OBJECTIVE

To compare 2 procedures for metroplasty: resectoscopy with monopolar knife versus small-diameter hysteroscopy fitted with a Versapoint device.

DESIGN

Prospective randomized study (Canadian Task Force classification I).

SETTING

Endoscopic gynecology units at tertiary care university hospitals.

PATIENTS

One hundred-sixty patients with septate uterus and a history of recurrent abortion or primary infertility undergoing hysteroscopic metroplasty from 2001 to 2005.

INTERVENTIONS

Hysteroscopic resection of the uterine septum performed with either a 26F resectoscope with unipolar knife (80 women, group A) or a 5-mm diameter hysteroscope with Versapoint device (80 women, group B). All patients were managed expectantly, with follow-up lasting 1 year.

MEASUREMENTS AND MAIN RESULTS

Operative parameters (operative time, fluid absorption, complications, need for second intervention) and reproductive outcome parameters (pregnancy, abortion, term and preterm delivery, modality of delivery, cervical cerclage) were measured. Operative time and fluid absorption were significantly greater in group A than in group B (23.4 +/- 5.7 vs 16.9 +/- 4.7 minutes and 486.4 +/- 170.0 vs 222.1 +/- 104.9 mL, respectively). The cumulative complication rate was significantly lower in group B than in group A. No difference in any of the reproductive parameters was observed between the 2 groups: pregnancy and delivery rates were 70% and 81.6% in group A vs 76.9% and 84% in group B. Nine women (18.4%) from group B and 8 women (16%) from group B experienced spontaneous abortions. Most patients (54/82) delivered by cesarean section without differences according to the hysteroscopic technique used for metroplasty (65% in group A vs 67.7% in group B) or to the gestational age (65.1% of term and 68.7% of preterm deliveries).

CONCLUSIONS

Small-diameter hysteroscopy with bipolar electrode for the incision of uterine septum is as effective as resectoscopy with unipolar electrode regarding reproductive outcome and is associated with shorter operating time and lower complication rate.

Fertility and pregnancy outcomes following hysteroscopic septum division

OBJECTIVES

We sought to evaluate retrospectively the efficacy of hysteroscopic metroplasty in a population of women with a history of recurrent pregnancy loss or infertility who were also known to have a uterine septum.

METHODS

Hysteroscopic metroplasty was performed on 26 women with a uterine septum and a history of either recurrent pregnancy loss or infertility. The metroplasty was performed using a Versapoint bipolar needle device (in 23% of cases) or a resectoscopic knife electrode with cutting current (in 77% of cases). The main outcome measures were rates of clinical pregnancy and live birth.

RESULTS

Nineteen women had a hysteroscopic metroplasty because of recurrent pregnancy loss. Postoperatively, the pregnancy rate was 95%, and the live birth rate was 72%. The seven infertile patients had pregnancy and live birth rates of 43% and 29%, respectively.

CONCLUSION

Hysteroscopic metroplasty using either the Versapoint bipolar needle device or a knife electrode is both safe and effective. In women with recurrent pregnancy loss, future fertility is not impaired, and live birth rates are significantly improved.

The diagnosis and reproductive outcome after surgical treatment of the complete septate uterus, duplicated cervix and vaginal septum

OBJECTIVE

This study was undertaken to evaluate the diagnostic management and the reproductive outcome after surgical repair of a rare reproductive malformation.

STUDY DESIGN

Sixteen women with a complete septate uterus, double cervix, and a longitudinal vaginal septum were referred for evaluation. Presenting complaints were chiefly pregnancy loss in parous women (n=9) and dyspareunia in nulligravid women (n=7). The combination of hysterosalpingography, ultrasonography, and/or magnetic resonance imaging was used to correctly identify the anomaly in 15 of the 16 cases. Both hysteroscopic (n=11) and transabdominal (n=5) surgical techniques were used to repair the uterine septum.

RESULTS

In no case was the correct diagnosis made before referral; the uterus didelphys was the most common misdiagnosis. The preoperative pregnancy loss was 81%. Postoperatively, 12 women conceived for a total of 17 pregnancies; there were 14 term live births or ongoing pregnancies in the third trimester (82%), with a first trimester spontaneous abortion rate of 18%. In 9 women who conceived after hysteroscopic surgery, term live births occurred in 9 of 12 (75%) conceptions. A modified Tompkins metroplasty was performed in 5 women with subsequent term live births or ongoing third trimester pregnancies in 5 of 5 (100%) patients.

CONCLUSION

The identification of a duplicated cervix and a vaginal septum is consistent with several uterine malformations, which leads to frequent misdiagnosis and errors in management. Significant pregnancy wastage, obstetric complications, and dyspareunia are common, and surgical treatment is therefore advisable. Making the best choice between hysteroscopic or transabdominal metroplasty depends on the anatomic features of the cervix and the uterine cavity, but optimal patient management requires familiarity with both techniques.

Hysteroscopic septum resection using the Versapoint system in subfertile women

The aim of the present study was to assess the safety and efficacy of hysteroscopic septum resection by Versapoint. Forty-five subfertile patients who underwent hysteroscopic septum resection using the Versapoint system were analysed. A type Va and a type Vb septate uterus were present in 10 (22.2%) and 35 (77.8%) patients respectively. Complete septum excision was feasible in all patients. No complications occurred during septum resection. Repeat hysteroscopy 2 months after septum excision showed normal endometrial cavity in all patients. Hysteroscopic septum resection by Versapoint system is a safe and efficient method.

Clinical implications of sonographic detection of uterine anomalies for reproductive outcome

The purpose of this review article was to analyze the literature on the prevalence, diagnosis and treatment of the congenital uterine anomalies and to discuss current dilemmas on their influence on reproductive outcome. Congenital uterine anomalies are commonly associated with repeated pregnancy failure, in particular an increased risk of first- and second-trimester miscarriages and preterm delivery. Recent reports on two-dimensional and three-dimensional transvaginal ultrasound and saline contrast sonohysterography appear promising for diagnosis and classification of congenital uterine anomalies. The ability to visualize both the uterine cavity and the fundal uterine contour on a three-dimensional scan facilitates the diagnosis of uterine anomalies and enables differentiation between septate and bicornuate uteri. Color Doppler ultrasound allows visualization of intraseptal vascularity and may help in distinguishing the avascular from the vascular septum. Less connective tissue in the septum may result in poor decidualization and placentation, while an increased amount of muscle tissue in the septum can cause miscarriage by the production of local uncoordinated myometrial contractility. Hysteroscopic septum excision is an effective procedure which improves live-birth rates. Because of its simplicity, minimal invasiveness, low morbidity and low cost, a more liberal approach to the treatment of uterine anomalies is being advocated.

Successful pregnancy after in-vitro fertilization and transmyometrial embryo transfer in a patient with congenital atresia of cervix: case report

A case report of a patient with congenital cervical atresia diagnosed at the age of 24 years is given. The attempts to create a neocervix were unsuccessful. Since no signs of retrograde menstruation or haematometra were observed, in agreement with the patient hysterectomy was not performed. At the age of 32 years, a successful pregnancy was achieved after an in-vitro fertilization and transmyometrial embryo transfer. Due to rapidly progressing pre-eclampsia, an elective Caesarean section was performed at 32 weeks gestation. A 1610 g healthy male infant in breech presentation was born. The post-partum period was uneventful.

Management of septate uterus by flexible hysteroscopy and Nd:YAG laser

OBJECTIVE

To evaluate the efficiency of flexible Nd-YAG laser hysteroscopic metroplasty.

METHODS

We present a retrospective study of 17 patients treated for septate uteri between 1990 and 1995. The indication of hysteroscopy was recurrent abortion in nine cases and eight with primary infertility with indication of IVF in another five cases. We did not prescribe any pretreatment. A flexible hysteroscope with a 100-W Nd:YAG laser was used with glycine-controlled flow. The septum was divided by the laser after exploration of the cavity. We proposed a control office hysteroscopy 2 months after surgery to prevent uterine adhesions.

RESULTS

There was no complication. Twelve patients conceived with 10 live births at term and two spontaneous abortions. Four are still infertile, two were lost from the study and two no longer desired pregnancy. Resectoscopic studies showed the same results.

CONCLUSION

The advantages of this method are the excellent ergonomic properties of the fibroscope and the safety of the laser. We suggest that metroplasty does not improve the pregnancy rate but only the pregnancy outcome of these patients. However, for those with the indication of IVF the procedure seems useful in avoiding abortion.
