Mayer-Rokitansky-Kuster-Hauser syndrome: a review

A rare variant of mullerian agenesis: a case report and review of the literature

INTRODUCTION

Menstruation is a developmental milestone and usually marks healthy and normal pubertal changes in females. Menarche refers to the onset of first menstruation in a female. The causes of primary amenorrhea include outflow tract abnormalities, resistant endometrium, primary ovarian insufficiency, and disorders of the hypothalamus, pituitary, or other endocrine glands. A rare variant of mullerian agenesis, which warrants an individualized approach to management, is presented here.

CASE REPORT

We present here the case of a 25-year-old Indian female with pain in the lower abdomen and primary amenorrhea. After a thorough history, clinical examination, imaging, and diagnostic laparoscopy, two small uteri, a blind upper half vagina, bilateral polycystic ovaries, and a blind transverse connection between the two uteri-a horseshoe band cervix-were detected, which confirmed the diagnosis of mullerian agenesis. There was evidence of adenomyosis in the mullerian duct element. This is a rare form of Müllerian abnormality with an unusual presentation.

CONCLUSION

Mullerian agenesis is the most common cause of primary amenorrhea with well-developed secondary sexual characteristics. There are various forms of mullerian agenesis. Most of the cases are managed by a multidisciplinary team. Rare variants warrant an individualized approach to management.

Laparoscopic Davydov vs. laparoscopic Vecchietti neovaginoplasty in women with Mayer-Rokitansky-Küster-Hauser syndrome; a systematic review and meta-analysis

OBJECTIVE

To summarize the available evidence on the laparoscopic Davydov and Vecchietti methods to create a neovagina and to compare these techniques with a focus on neovaginal length, sexual function, operative time, and complications.

DESIGN

A systematic electronic search up to August 2022 using PubMed and Embase is performed.

SETTING

Not applicable.

PATIENTS

Women with Mayer-Rokistansky-Küster-Hauser syndrome.

INTERVENTIONS

All published clinical studies concerning the laparoscopic Davydov and laparoscopic Vecchietti procedures as a surgical technique to create a neovagina in women with Mayer-Rokistansky-Küster-Hauser syndrome were obtained. The guidelines for the preferred reporting items for systematic reviews and meta-analysis were followed. The following data were extracted: operative time, hospital stay, major early complications (within 3 months postsurgery), dilation therapy, neovaginal length, vaginal discharge, vaginal stenosis, time to sexual activity, sexual satisfaction, penetrative sexual activity, dyspareunia, score on the Female Sexual Function Index (FSFI), and duration of follow-up. The Newcastle Ottawa Scale was used to assess the quality of articles.

MAIN OUTCOME MEASURES

Neovaginal length, FSFI scores, operative time, and complications.

RESULTS

A total of 1,163 articles were identified, of which 31 studies were included in this systematic review. Of these, 12 studies (380 patients) are related to the Davydov method, 17 studies (804 patients) to the Vecchietti method, and 2 articles concern both. There is clinical heterogeneity and variety in the quality of the studies. Nineteen studies were included in the meta-analyses. The mean neovaginal length 12 months after the Davydov method is 8.3 cm (95% confidence interval [CI] 8.1-8.6), vs. 8.7 cm (95% CI 7.2-10.3) after the Vecchietti method. The mean FSFI score after the Davydov method is 28.9 (95% CI 26.8-31.1), compared with 27.5 (95% CI 25.0-30.1) after the Vecchietti method. The operative time of the Davydov method is 126 minutes (95% CI 109-143), compared with 40 minutes (95% CI 35-45) of the Vecchietti method.

CONCLUSIONS

The operations yield comparable neovaginal length, sexual function, and complication rates. The mean FSFI scores indicate no sexual dysfunction in either group. The operative time of the Davydov method is significantly longer. There is no superiority shown for one of the surgical techniques in functional terms.

Atypical form of Mayer-Rokitansky-Küster-Hauser syndrome: A case report

Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) is a congenital disorder syndrome characterized by failure of the uterine and vaginal organs to develop normally. The prevalence of MRKH is estimated to occur in about 1 in 5000 of female live births. A 25-year-old female patient comes to a general obstetric and gynecological polyclinic with complaints of not being able to menstruate at all since birth. There is a history of vaginal discharge but it is neither viscous nor had an odor. On ultrasound examination, the structure of the uterus and ovaries was not found in a normal place. On follow up MRI examination showed agenesis of the uterus and proximal two-third of the vagina accompanied by abnormal positioning of both ovaries, thus supporting to atypical form of MRKHS. The patient is not given drug therapy, but she was planned to transplant the uterine organs. This case report suggests MRKH syndrome can be characterized by ectopic ovaries and a uterus that is not fully developed and can also be accompanied by agenesis of the vaginal organs. Pelvic ultrasound is the main modality chosen to be performed in patients with symptoms of primary amenorrhea. When pelvic organs cannot be visualized properly, it will be performed MRI examination. MRI examination is known to have sensitivity and specificity up to 100% in diagnosing MRKH syndrome. This case report describes a 25-year-old woman with primary amenorrhea with MRKH syndrome. MRI is a sensitive and specific examination to confirm the diagnosis.

Clinical features of Mayer-Rokitansky-Küster-Haüser syndrome diagnosed at under 16 years old: results from a questionnaire survey conducted on all institutions of pediatric surgery and pediatric urology in Japan

PURPOSE

Mayer-Rokitansky-Küster-Häuser syndrome (MRKH) usually presents with primary amenorrhea after puberty. The present study clarified the clinical features of MRKH diagnosed at under 16 years old.

METHODS

We conducted a questionnaire survey to determine the status of MRKH in Japan. Twenty-one MRKH patients were enrolled, and the patient background and clinical features were analyzed.

RESULTS

The median age at the diagnosis was 2.6 [1.0-9.0] years. Three patients (14.3%) were diagnosed with type I MRKH, while 18 (85.7%) were diagnosed with type II. The associated anomalies included (some cases overlapped): anorectal malformation (ARM) (n = 13, 72.2%), renal malformation (n = 12, 66.7%), vertebral malformation (n = 11, 61.1%), esophageal atresia (n = 5, 27.8%), and cardiac malformation (n = 4, 22.2%). The comparison of patients with and without ARM revealed that patients with ARM were significantly younger than those without ARM at the time of the diagnosis (1.5 [1-2.6] years vs. 9.1 [8.2-11.7] years, p < 0.05). Associated ARM was the most frequent reason for the diagnosis of MRKH (n = 10, 47.6%).

CONCLUSIONS

MRKH patients with some associated anomalies, especially ARM, were frequently diagnosed in preoperative imaging examinations or radical operation for ARM. Pediatric surgeons should pay close attention to female patients with ARM to prevent errors in the diagnosis of MRKH.

Precocious puberty or growth hormone deficiency as initial presentation in Mayer-Rokitansky-kuster-Hauser syndrome: a clinical report of 5 cases

Background

We report five patients with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS), four of whom presented with precocious puberty and one with growth hormone deficiency (GHD. Our five children add to the growing endocrine data base of MRKHS.

Case presentation

We retrospectively reviewed clinical data of 5 MRKHS patients from 2017 to 2020. The clinical features, hormonal profiles, radiological imaging and genetic analyses were collated. The age range of the 5 patients at diagnosis was 6.7–9.1 years. Four presented with premature thelarche, and one presented with short stature. External genitalia were normal in all patients. Gonadotropin-releasing hormone stimulation tests for the 5 patients revealed peak luteinizing hormone and follicular stimulating hormone levels of 3.57, 6.24, 11.5, 4.44 and 4.97 IU/L and 9.41, 16.7, 13.8, 14.2 and 10.3 mIU/mL, respectively. Growth hormone stimulation for one patient with short stature was consistent with GHD with a peak level of GH was 7.30 ng/mL. Imaging disclosed advanced bone age in four patients and no skeletal abnormalities in any of the patients. Ultrasonography of the abdomen revealed bilateral polycystic kidneys in one patient. Pelvic magnetic resonance imaging confirmed no uterus in five patients. All of the patients had a normal karyotype (46, XX). In one patient, whole-exome sequencing detected a deletion of 17q12(chr17:36,046,434–36,105,050, hg19) encompassing the HNF1B gene.

Conclusions

We report the unusual co-occurrence of precocious puberty and GHD in patients with MRKHS, highlighting that abnormal puberty and growth development may represent initial unexplained manifestations. Whether the deletion of 17q 22 begat GHD is unclear.

Postoperative outcomes of sigmoid colon vaginoplasty for vaginal agenesis: A randomized controlled trial

Objective

Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) is a rare disorder in women that is associated with vaginal agenesis and hypoplasia or loss of uterus. In this study we aim to study the outcome of sigmoid colon vaginoplasty among MRKH patients with vaginal agenesis.

Methods

In this randomized clinical trial study, from 2017 to 2021, 39 patients were reported to our center with vaginal agenesis as a result of MRKH. Patients were treated with sigmoid colon vaginoplasty and postoperative outcomes such as Female sexual function index (FSFI), depth of vaginal cavity, and postoperative complications were evaluated.

Results

The mean age of the patients was 32.3 ± 2.3 years. 18 patients (46.2%) were diagnosed using MRI whereas 21 patients (53.8%) were diagnosed with exploratory laparoscopy. The mean vaginal depth before and after the surgery was 2.8 cm and 17.3 cm, respectively. One patient (2.6%) developed fistula, and peritonitis due to perforation of the vagina, 26 months after surgery, respectively. Of 10 patients who were sexually active after the surgery, all of these patients were sexually satisfied. The FSFI was 32 ± 3.9.

Conclusion

The postoperative complications after sigmoid colon vaginoplasty were minimum and all the sexually active patients were sexually active. This method appears to be an effective for surgical treatment of vaginal agenesis.

•

Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) is a rare disorder in women.

•

That is associated with vaginal agenesis and hypoplasia or loss of uterus.

•

Sigmoid colon vaginoplasty were minimum and all the sexually active patients were sexually active.

•

This method appears to be an effective for surgical treatment of vaginal agenesis.

The Effect of Psychosexual Education on Promoting Sexual Function, Genital Self-Image, and Sexual Distress among Women with Rokitansky Syndrome: A Randomized Controlled Clinical Trial

STUDY OBJECTIVE

To assess the effectiveness of psychosexual education on promoting sexual function and genital self-image and reducing sexual distress through e-learning among women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.

DESIGN

Randomized controlled trial.

SETTING

Imam Khomeini Hospital "Pelvic Floor Clinic" in Tehran.

PARTICIPANTS

Thirty-eight 15- to 49-year-old women with MRKH syndrome who had undergone surgical or nonsurgical vaginal reconstruction techniques more than 6 months before the intervention were assigned to 2 parallel intervention and control groups of 19 each.

INTERVENTIONS

Psychosexual education was delivered through e-learning for the intervention group over an 8-week period, with no limitations of time and space. Sexual function, genital self-image, and sexual distress were evaluated at baseline, and at 4 and 8 weeks after the intervention.

MAIN OUTCOME MEASURES

The data collection tools included the Persian version of the Female Sexual Function Index, Female Genital Self-Image Scale, and the Revised Female Sexual Distress Scale.

RESULTS

The between group mean differences of sexual function, genital self-image, and sexual distress after 4 weeks (-1.2 [95% CI, -2.1 to -0.1], P = .025; -1.9 [95% CI, -2.9 to -0.9], P < .001; 4.2 [95% CI, 2.0-6.4], P < .001, respectively), as well as after 8 weeks (-1.8 [95% CI, -3.1 to -0.5], P = .009; -3.0 [95% CI, -4.5 to -1.5], P < .001; 6.7, 95% CI, 3.9-9.6], P <0.001, respectively) after baseline were significant.

CONCLUSION

Psychosexual education improved sexual function and genital self-image and reduced sexual distress in women with MRKH syndrome. Therefore, using this approach, we can raise individuals' sexual knowledge and skills and correct their sexual beliefs and attitudes.

Dissociative disorder in Mayer Rokitansky Küster Hauser syndrome with pulmonary agenesis: a case report

Background

The Mayer Rokitansky Küster Hauser (MRKH) syndrome is a rare congenital disorder characterized by the absence of uterus and vagina in a patient who is phenotypically a female, with 46 XX karyotypes. It affects 1 in 4000 to 5000 female new-borns. Pulmonary agenesis is a rare association in this MRKH syndrome. Females with MRKH face various mental health issues and psychological disturbances, including dissociative disorder which is a stress-related psychiatric disorder. Dissociative disorder in MRKH syndrome is under-recognized and under-treated.

Case presentation

A 23-year-old unmarried woman presented to the emergency forabnormal behaviour attack. Recurrent episodes of dissociative convulsions were present most of the time with MRKH syndrome as the pertinent stressor. Both antidepressants and psychotherapy helped to decrease the frequency of dissociative convulsions and come interms with the syndrome.

Conclusion

This case describes dissociative disorder as the presentation and comorbid condition of MRKH syndrome and the impact of MRKH syndrome on the patient. We attempt to explain the occurrence of dissociative disorder in MRKH syndrome and the results of under-recognition and under-treatment of the same. We aim to highlight the presence of commonly treatable conditions associated with a rare syndrome and its effect when untreated and unrecognized.

Chronic pelvic pain in a patient with Mayer-Rokitansky-Küster-Hauser syndrome: An unusual presentation

Introduction:

MRKH syndrome, is a spectrum of congenital anomalies of unknown aetiology characterised by a variable degree of utero-vaginal agenesis in women with normal secondary sexual characteristics and a 46, XX karyotype.

Case report:

A 16 year old unmarried presented with absence of menses and chronic pelvic pain. MRKH with endometrioma was diagnosed on MRI. Laparoscopic removal of the Mullerian mass with endometriotic cyst was done. The diagnosis was subsequently confirmed on histology.

Conclusion:

This case highlights the atypical presentation of MRKH and reinforce the Sampsons theory of retrograde menstruation in the development of endometriosis. Patient with chronic pelvic pain and MRKH syndrome should be evaluated for endometriosis.

Unicornuate uterus with a functional non-communicating horn in adolescent

Common causes of pelvic pain are primary dysmenorrhoea, Müllerian duct anomalies, outflow obstruction, leiomyoma, endometriosis and adenomyosis. Unicornuate uterus with a rudimentary horn is a rare congenital malformation of the female genital tract, asymptomatic because of lack of functional endometrium. This study presents a rare case of a non-communicating functional rudimentary horn. A 16-year-old unmarried Yemeni female adolescent with a history of irregular painful menstrual period visited Obstetrics and Gynaecology outpatient clinic. Pelvic ultrasound was conducted showing an asymmetrical uterine configuration with the non-communicating rudimentary horn on the right side. Laparoscopic excision of the horn was planned for the patient. Non-communicating rudimentary horn with functional endometrium should be considered as a differential diagnosis in the female adolescent with obstructive uterine symptoms. Early diagnosis is crucial. Using the laparoscopic approach, an expert surgeon prefers definitive management to excise the rudimentary horn.

A case of neovagina surgical creation using the uterine cervix remnant in a patient with Mayer-Rokitansky-Küster-Hauser syndrome

OBJECTIVE

To study the efficacy of a novel approach to vaginoplasty in a patient with vaginal aplasia and a preserved cervix.

DESIGN

We present the case of a 28-year-old patient who was referred with a history of absent menstruation and vaginal intercourse was absent as well as abnormal development of the internal genitals. The patient underwent a laparoscopic cystectomy in 2012 because of an ovarian cyst and later that year underwent laparotomic supracervical hysterectomy with bilateral salpingectomy because of severe pain caused by a hematometra in their uterine remnant. In the period from 2013 to 2016, multiple pelvic ultrasound examinations revealed a fluid structure in the pelvis. By 2020, the size of the lesion had increased to 10 cm on average. A computed tomography scan and magnetic resonance imaging showed a mucinous lesion in the lower part of the patient's pelvis resembling the cervical origin. No pathology of the urinary tract was found. A laparoscopic approach was chosen to achieve the two main goals of the patient-the possibility of vaginal intercourse and the treatment of the intraabdominal lesion. The procedure started with a vaginal step when the neovagina dissection was performed as in the classical Davydov technique up to the beginning of the dilated cervical remnant. Bilateral ureterolysis was performed laparoscopically to prevent ureteral injury. The peritoneum was widely dissected from both the anterior and posterior surfaces of the uterine cervix, which appeared as a large structure filled with typical cervical mucus. Partial dissection of the sacrouterine and ovarian ligaments on both sides was performed to mobilize the cervix. A transverse incision of the cystically dilated cervix in the cranial part was performed and the edges of the incision were brought down to the introitus of the vagina. The cervicovulvar anastomosis was fixed by separate sutures with Vicryl 2-0.

SETTING

The surgery was performed in an inpatient setting equipped with conventional laparoscopic instruments, a 30-degree laparoscope, a high-definition video system, xenon light source, insufflator, irrigator, and bipolar and monopolar energy sources.

PATIENT(S)

A single patient, mentioned previously.

INTERVENTION(S)

Surgical vaginoplasty using the preserved cervix. The details are explained in the Design section.

MAIN OUTCOME MEASURE(S)

Restoration of the normal vaginal anatomy and function.

RESULT(S)

In the postoperative period, the patient did not have any postoperative complications. The urinary catheter was removed on the first postoperative day. From day 1, the patient was taught to make daily vaginal dilations with a vaginal dilator to maintain normal vaginal depth and width. The patient was discharged on day 3 after surgery. In a 3-month follow-up visit, the patient's vagina appeared normal in size with transverse folds and was very well lubricated because of the natural secretions of the cervical mucosa. The patient had been sexually active by the time of the follow-up visit.

CONCLUSION(S)

According to a literature search, this was the first published case of a successful neovagina creation through cervicovulvar anastomosis. Although different surgical approaches were widely discussed in previous publications of Fertility and Sterility, such as "Laparoscopic uterovaginal anastomosis in Mayer-Rokitansky-Küster-Hauser syndrome with functioning horn", "Laparoscopy-assisted Ruge procedure for the creation of a neovagina in a patient with Mayer-Rokitansky-Küster-Hauser syndrome", and "Evaluation of amnion in creation of neovagina in women with Mayer-Rokitansky-Küster-Hauser syndrome", which were all variants of vaginoplasty with allograft, vaginal distention (Vecchietti procedure), or the use of native tissues (Davydov technique), our approach could be more feasible in the rare cases of preserved distended cervix because of less induced trauma when compared with that of cervical removal. This is because of the strong and lubricated nature of the cervical epithelium, which is already present and does not require time for epithelization.

Disorders of sex development and female reproductive capacity: A literature review

Disorders of sex development (DSD) are a wide-ranging group of complex conditions that influence chromosomal, gonadal, and phenotypic sex. The prevalence of DSD is very low, but affected patients deserve individualized management to improve psychological, sexual, and reproductive outcomes. This review aims to clarify the fertility potential of DSD patients who can be reared as females and their chance of becoming pregnant, especially using assisted reproductive techniques (ART). Due to the effects of DSD on internal and external genital organs, these conditions result in varying degrees of fertility potential. Fertility rate depends on the phenotype and is inversely related to the severity of the disorder. Reproductive endocrinologists and infertility specialists must be considered active partners of the interdisciplinary treatment team. With current advances in ART, pregnancy is more achievable in patients who were considered infertile at first glance. Due to the complexity of the medical management in DSD patients, more studies should be conducted to conclusively suggest the best choice for improving their fertility potential.Abbreviations: AIS: Androgen Insensitivity Syndrome; AMH: Anti-Müllerian Hormone; ART: Assisted Reproductive Technology; ASRM: American Society for Reproductive Medicine; CAH: Congenital Adrenal Hyperplasia; CAIS: Complete Androgen Insensitivity Syndrome; DHT: Dihydrotestosterone; DSD: Disorders of Sexual Development; FSH: Follicle Stimulating Hormone; GD: Gonadal Dysgenesis; ICSI: Intracytoplasmic Sperm Injection; IUGR: Intrauterine Growth Restriction; IVF: In Vitro Fertilization; IVF-ET: IVF and Embryo Transfer; LH: Luteinizing Hormone; MGD: Mixed Gonadal Dysgenesis; MRI: Magnetic Resonance Imaging; MRKH: Mayer-Rokitansky-Kuster-Hauser; US: Ultrasonography; HSG: Hysterosalpingography; PAIS: Partial Androgen Insensitivity Syndrome; PGD: Preimplantation Genetic Diagnosis; POR: P450 Oxidoreductase; PROM: Premature Rupture of Membranes; TS: Turner Syndrome; 17β-HSD III: 17β-Hydroxysteroid Dehydrogenase III; 21-OHD: 21-hydroxylase deficiency; 5α-RD-2: 5α-reductase-2.

Towards a bioengineered uterus: bioactive sheep uterus scaffolds are effectively recellularized by enzymatic preconditioning

Uterine factor infertility was considered incurable until recently when we reported the first successful live birth after uterus transplantation. However, risky donor surgery and immunosuppressive therapy are factors that may be avoided with bioengineering. For example, transplanted recellularized constructs derived from decellularized tissue restored fertility in rodent models and mandate translational studies. In this study, we decellularized whole sheep uterus with three different protocols using 0.5% sodium dodecyl sulfate, 2% sodium deoxycholate (SDC) or 2% SDC, and 1% Triton X-100. Scaffolds were then assessed for bioactivity using the dorsal root ganglion and chorioallantoic membrane assays, and we found that all the uterus scaffolds exhibited growth factor activity that promoted neurogenesis and angiogenesis. Extensive recellularization optimization was conducted using multipotent sheep fetal stem cells and we report results from the following three in vitro conditions; (a) standard cell culturing conditions, (b) constructs cultured in transwells, and (c) scaffolds preconditioned with matrix metalloproteinase 2 and 9. The recellularization efficiency was improved short-term when transwells were used compared with standard culturing conditions. However, the recellularization efficiency in scaffolds preconditioned with matrix metalloproteinases was 200–300% better than the other strategies evaluated herein, independent of decellularization protocol. Hence, a major recellularization hurdle has been overcome with the improved recellularization strategies and in vitro platforms described herein. These results are an important milestone and should facilitate the production of large bioengineered grafts suitable for future in vivo applications in the sheep, which is an essential step before considering these principles in a clinical setting.

Effects of different vaginal mould use approaches after vaginoplasty with artificial dermis in patients with Mayer-Rokitansky-Küster-Hauser syndrome

OBJECTIVE

To assess the therapeutic effects of different vaginal mould use approaches after vaginoplasty in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.

METHODS

Patients with MRKH syndrome who underwent surgery from 2010 to 2015 in our hospital were retrospectively evaluated. Vaginoplasty was performed with artificial dermis, and vaginal moulds were used for 6 months postoperatively. The patients were divided into an intermittent group and continuous group according to the vaginal mould approach.

RESULTS

Thirty-five patients were evaluated (intermittent group, 19 patients; continuous group, 16 patients). One month postoperatively, the mean vaginal length and width in the intermittent group were 9.26 ± 0.56 and 3.82 ± 0.25 cm, respectively, and those in the continuous group were 9.44 ± 0.51 and 3.86 ± 0.22 cm, respectively. Six months postoperatively, the mean vaginal length and width in the intermittent group were 8.94 ± 0.71 and 3.76 ± 0.26 cm, respectively, and those in the continuous group were 8.69 ± 0.48 and 3.65 ± 0.30 cm, respectively. The mean Female Sexual Function Index scores in the intermittent and continuous groups were 28.61 ± 0.71 and 28.4 80 ±0.79 respectively, after normal sexual life.

CONCLUSION

Both intermittent and continuous use of postoperative vaginal moulds may be effective.

Laparoscopic Davydov's Colpopoiesis for a Case of Mayer-Rokitansky-Kuster-Hauser (MRKH) Syndrome

Congenital absence of vagina and uterus has been eponymously called Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. The vagina may appear as a dimple with the presence of rudimentary uterine primordia and normal functioning ovaries. Its incidence is 1 in 4500 to 5000 female. Patients present with primary amenorrhea, normal external genitalia, and well-developed secondary sexual characteristics. Davydov’s colpopoiesis is one of the methods of vaginoplasty using the patient’s own peritoneum as a graft to line the neovagina. We present here a case of MRKH Syndrome where a laparoscopic Davydov procedure was chosen for vaginal reconstruction.

Protein-protein interaction network analysis applied to DNA copy number profiling suggests new perspectives on the aetiology of Mayer-Rokitansky-Küster-Hauser syndrome

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare disease, characterised by the aplasia of vagina and uterus in women with a 46,XX karyotype. Most cases are sporadic, but familial recurrence has also been described. Herein, we investigated an Italian cohort of 36 unrelated MRKH patients to explore the presence of pathogenic copy number variations (CNVs) by array-CGH and MLPA assays. On the whole, aberrations were found in 9/36 (25%) patients. Interestingly, one patient showed a novel heterozygous microduplication at Xp22.33, not yet described in MRKH patients, containing the PRKX gene. Moreover, a novel duplication of a specific SHOX enhancer was highlighted by MLPA. To predict the potential significance of CNVs in MRKH pathogenesis, we provided a network analysis for protein-coding genes found in the altered genomic regions. Although not all of these genes taken individually showed a clear clinical significance, their combination in a computational network highlighted that the most relevant biological connections are related to the anatomical structure development. In conclusion, the results described in the present study identified novel genetic alterations and interactions that may be likely involved in MRKH phenotype determination, so adding new insights into the complex puzzle of MRKH disease.

Evaluation and Management of Unexpected Functional Rudimentary Uteri in Mayer-Rokitansky-Küster-Hauser Syndrome of Chinese Women

Objective

To elucidate the characteristics of symptomatic attack of rudimentary uteri in MRKH syndrome and highlight the rare and unexpected possibilities.

Methods

A cohort of 202 Chinese MRKH syndrome patients admitted to the Peking Union Medical College Hospital from Jan 2009 to Dec 2016 was analyzed retrospectively. Based on the symptoms of abdominal pain before vaginoplasty, the patients were categorized into the asymptomatic and symptomatic groups.

Results

Totally, 21 patients had their uteri removed due to obstructive bleeding, 19 of them had symptoms of abdominal pain before vaginoplasty, the mean duration of abdominal pain before artificial vaginoplasty was 5.0 years (range, 0.5-10 years), and the mean age at first onset of recurrent abdominal pain was 14.3 years old (range 11-18). Two special cases showed unusual long incubation periods up to 23 years. Ultrasound detected endometrioid echo in four asymptomatic patients. Among the symptomatic group, 7 patients had no imaging evidence for endometrial cavities despite clinical pain. Two of them developed severe symptoms over the next two or four years and eventually had their uteri removed. Two patients reported persistent abdominal pain with a visual analog scale (VAS) score of 4-5, still under observation. Three patients were lost to follow-up.

Conclusion

More than 10% of the patients with MRKH syndrome had surgical indication to remove the rudimentary uteri. The discrepancy between clinical symptoms and imaging calls for the vigilance for prophylactic surgery or prolonged follow-up.

The development of the human uterus: morphogenesis to menarche

There is emerging evidence that early uterine development in humans is an important determinant of conditions such as ontogenetic progesterone resistance, menstrual preconditioning, defective deep placentation and pre-eclampsia in young adolescents. A key observation is the relative infrequency of neonatal uterine bleeding and hormone withdrawal at birth. The origin of the uterus from the fusion of the two paramesonephric, or Müllerian, ducts was described almost 200 years ago. The uterus forms around the 10th week of foetal life. The uterine corpus and the cervix react differently to the circulating steroid hormones during pregnancy. Adult uterine proportions are not attained until after puberty. It is unclear if the endometrial microbiome and immune response-which are areas of growing interest in the adult-play a role in the early stages of uterine development. The aim is to review the phases of uterine development up until the onset of puberty in order to trace the origin of abnormal development and to assess current knowledge for features that may be linked to conditions encountered later in life. The narrative review incorporates literature searches of Medline, PubMed and Scopus using the broad terms individually and then in combination: uterus, development, anatomy, microscopy, embryology, foetus, (pre)-puberty, menarche, microbiome and immune cells. Identified articles were assessed manually for relevance, any linked articles and historical textbooks. We included some animal studies of molecular mechanisms. There are competing theories about the contributions of the Müllerian and Wolffian ducts to the developing uterus. Endometrium features are suggestive of an oestrogen effect at 16-20 weeks gestation. The discrepancy in the reported expression of oestrogen receptor is likely to be related to the higher sensitivity of more recent techniques. Primitive endometrial glands appear around 20 weeks. Features of progestogen action are expressed late in the third trimester. Interestingly, progesterone receptor expression is higher at mid-gestation than at birth when features of endometrial maturation are rare. Neonatal uterine bleeding occurs in around 5% of neonates. Myometrial differentiation progresses from the mesenchyme surrounding the endometrium at the level of the cervix. During infancy, the uterus and endometrium remain inactive. The beginning of uterine growth precedes the onset of puberty and continues for several years after menarche. Uterine anomalies may result from fusion defects or atresia of one or both Müllerian ducts. Organogenetic differentiation of Müllerian epithelium to form the endometrial and endocervical epithelium may be independent of circulating steroids. A number of genes have been identified that are involved in endometrial and myometrial differentiation although gene mutations have not been demonstrated to be common in cases of uterine malformation. The role, if any, of the microbiome in relation to uterine development remains speculative. Modern molecular techniques applied to rodent models have enhanced our understanding of uterine molecular mechanisms and their interactions. However, little is known about functional correlates or features with relevance to adult onset of uterine disease in humans. Prepubertal growth and development lends itself to non-invasive diagnostics such as ultrasound and MRI. Increased awareness of the occurrence of neonatal uterine bleeding and of the potential impact on adult onset disease may stimulate renewed research in this area.

Transcriptional landscape of the embryonic chicken Müllerian duct

Background

Müllerian ducts are paired embryonic tubes that give rise to the female reproductive tract in vertebrates. Many disorders of female reproduction can be attributed to anomalies of Müllerian duct development. However, the molecular genetics of Müllerian duct formation is poorly understood and most disorders of duct development have unknown etiology. In this study, we describe for the first time the transcriptional landscape of the embryonic Müllerian duct, using the chicken embryo as a model system. RNA sequencing was conducted at 1 day intervals during duct formation to identify developmentally-regulated genes, validated by in situ hybridization.

Results

This analysis detected hundreds of genes specifically up-regulated during duct morphogenesis. Gene ontology and pathway analysis revealed enrichment for developmental pathways associated with cell adhesion, cell migration and proliferation, ERK and WNT signaling, and, interestingly, axonal guidance. The latter included factors linked to neuronal cell migration or axonal outgrowth, such as Ephrin B2, netrin receptor, SLIT1 and class A semaphorins. A number of transcriptional modules were identified that centred around key hub genes specifying matrix-associated signaling factors; SPOCK1, HTRA3 and ADGRD1. Several novel regulators of the WNT and TFG-β signaling pathway were identified in Müllerian ducts, including APCDD1 and DKK1, BMP3 and TGFBI. A number of novel transcription factors were also identified, including OSR1, FOXE1, PRICKLE1, TSHZ3 and SMARCA2. In addition, over 100 long non-coding RNAs (lncRNAs) were expressed during duct formation.

Conclusions

This study provides a rich resource of new candidate genes for Müllerian duct development and its disorders. It also sheds light on the molecular pathways engaged during tubulogenesis, a fundamental process in embryonic development.

An alternative approach to vaginal dilation in patients with Meyer-Rokitanski-Küster-Hauser syndrome: two case reports

Vaginal dilation, currently considered as the first-line therapy for vaginal aplasia in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, is a safe and effective treatment that aims to create a functional neovagina. However, rigid vaginal dilators classically described in the literature usually cause physical discomfort and side effects that can lead to vaginal necrosis. Here, we present two cases of MRKH syndrome patients with vaginal agenesis whose main complaint was the inability to have sexual intercourse with their partners. Considering unavailability of acrylic dilators and previous studies reporting good responses with the use of silicone dilators in women with post-radiotherapy vaginal stenosis, the medical team and patients opted for creation of a neovagina through the daily use of silicone vaginal dilators. Patient 1 developed an 8-cm vagina after 6 months of treatment and had a satisfactory sex life with her partner. Patient 2 developed a 7-cm vagina and reported significant symptom improvement. None of the patients developed side effects after the treatment. The use of inexpensive and easily accessible silicone vaginal dilators may be an effective and noninvasive alternative with few side effects for women with vaginal agenesis, particularly in the developing countries.

Laparoscopic sigmoid vaginoplasty: a salvage option for genitourinary fistula after failed McIndoe's repair

A 30-year-old woman presented with vesicovaginal fistula after a forceful intercourse. She was diagnosed as a case of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome 14 years ago and had underwent McIndoe's vaginoplasty using amniotic membrane. Similarly, another 14-year-old girl presented with an iatrogenic urethral and bladder neck injury during an attempt at McIndoe's vaginoplasty 4 months ago at another centre leading to urinary fistula with absent vagina. A laparoscopic salvage was done for both the cases along with repair of genitourinary fistula using sigmoid colon. There was no further requirement of vaginal dilation. Both patients remain fully continent at 1 year follow-up. Laparoscopic sigmoid vaginoplasty is a worthy minimally invasive salvage method for the patients of MRKH who develop fistulous complication after a previous attempt at neovagina creation. The bowel wall provides a structurally strong layer to withstand the repeated sexual trauma of the vagina.

Rare genital malformations in women's health research: sociodemographic, regional, and disease-related characteristics of patients with Mayer-Rokitansky-Küster-Hauser syndrome

BACKGROUND

The Mayer-Rokitansky-Küster-Hauser syndrome, MRKHS, is a rare (orphan) disease characterized by the aplasia or hypoplasia of the uterus and the vagina. In women's health research, little is known as to how much care provision for patients with MRKHS takes into account their socio-demographic together with their clinical characteristics. This work examines the patients' socio-demographic characteristics, highlighting issues of inappropriate and deficient provision of care.

METHODS

The study was carried out as part of the larger TransCareO project and included a group of N=129 MRKHS patients who underwent surgery between 2008 and 2012. Using a specially developed questionnaire, we analyzed MRKHS patients' data found both in the clinical documentation of the Department for Women's Health, University Hospital of Tübingen and the patient surveys of the Center for Rare Genital Malformations (CRGM/ ZSGF). Patients who took part in interviews were compared with non-respondents.

RESULTS

Patient respondents and non-respondents did not differ as to the parameters of interest. In most cases, primary amenorrhea was reported as an admission reason. In 24% of patients, a medical intervention (hymenal incision or hormone treatment) already occurred before admission to the Center in Tübingen and proper diagnosis of MRKHS. About one third received in advance inappropriate treatment. During the therapy, more than half of the patients were in a solid partnership. 10% of the family anamneses documented the occurrence of urogenital malformations.

CONCLUSIONS

Care provision for MRKHS patients is largely characterized by delayed proper diagnosis and in part, by inappropriate treatment attempts; there are also indications of regional differences. Anamnestic clues such as an asymptomatic amenorrhea or renal abnormalities of unclear origin still fail to result early enough in referral to a center on the basis of suspected MRKHS diagnosis. Urogenital malformations in the family are more common in patients than in the general population. For patients, a wide range of burdens are associated with the diagnosis. Abnormalities compared to their female peers occur, for instance, in the partnership status: MRKHS patients have more rarely a partner.

A young girl with right ovarian torsion and left ovarian ectopy

Background

Mayer-Rokitansky-Küster-Hauser (MRKHS) syndrome refers to congenital hypoplasia/aplasia of the uterus, the cervix and the upper 2/3 of the vagina, in females with normal ovaries and fallopian tubes, secondary sexual characteristics and 46 XX karyotype. This condition originates from abnormal development of Müller’s paramesonephric ducts in the early stages of embryonic development. Kidney agenesis or malformations are the most commonly associated with unilateral kidney agenesis. Ovaries may be ectopic in 16–19% of MRKHS patients. Primary amenorrhoea, due to the absence of the uterus, is the most common presentation. Female karyotype confirmation is mandatory to differentiate it from complete androgen insensitivity syndrome and 17-alpha-hydroxylase deficiency. The management of MRKHS is multidisciplinary in order to encompass psychological, medical and surgical issues.

Case presentation

A four-year-old girl, presented to the emergency department complaining of left groin swelling noted 2 days earlier. The patient had recently been evaluated for an episode of acute abdominal pain and vomiting, with a final diagnosis of right ovarian torsion. At that time, the ultrasound imaging was not able to identify the left kidney, the left ovary and uterus. Surgical abdominal exploration confirmed the right ovarian torsion and was not able to identify the left kidney and the left ovary. Only a remnant of the uterus was present. Therefore, the right ovary was removed, and a diagnosis of MRKHS was made. Ultrasound imaging showed a left inguinal hernia. The hernial sac consisted of a solid oval vascularized formation suggestive of an annexe. The patient underwent a surgical procedure to correct the left inguinal hernia. In the operating setting, the presence of a vascularized, ectopic ovary carrying the tuba inside the hernial sac was observed.

Conclusions

In front of a patient with ovarian torsion and anatomical features suggestive of MRKHS, both the ovaries should always be searched for, with a high suspicion threshold for extrapelvic ovary. Identifying the ectopic ovary, in this case, helped to preserve patient fertility, avoiding a possible torsion.

Typical and atypical pelvic MRI characteristics of Mayer-Rokitansky-Küster-Hauser syndrome: a comprehensive analysis of 201 patients

OBJECTIVES

To comprehensively evaluate the pelvic magnetic resonance imaging (MRI) findings of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and summarize the typical and atypical characteristics.

METHODS

A retrospective analysis of 201 consecutive MRKH patients was carried out. Pelvic MRI was reviewed by two experienced gynecological radiologists in consensus. Characteristics including the morphology, signal pattern and volumes of the uterine rudiments, location and volume of the ovaries, and the degree of vaginal dysgenesis were evaluated. Other noted abnormalities were also recorded.

RESULTS

Morphologically, the majority (95%) of patients displayed bilateral uterine rudiments combined with a fibrous band. The minority of patients showed no (3.5%) or unilateral (1.5%) uterine rudiments. A total of 385 uterine rudiments were detected which showed four types of signal patterns: one-layer differentiation (325, 84.4%), two-layer differentiation (27, 7%), three-layer differentiation without subsequent alteration (23, 6.0%), and three-layer differentiation with hematometra and/or ipsilateral hematosalpinx (10, 2.6%). The median volumes of these four types of uterine rudiments were 2.6 ml (1.69-3.81 ml), 3.19 ml (2.67-4.51 ml), 6.05 ml (3.37-12.44 ml), and 31.97 ml (19.2-38.7 ml), respectively. The mean ovarian volume was 6.49 ± 3.91 ml. Abnormally located ovaries were detected in 63 (31.3%) patients. The distal vagina was discernable in 25.1% of patients.

CONCLUSION

MRKH patients typically display bilateral uterine rudiments combined with a fibrous band and normally located ovaries. The uterine rudiments are generally small with only one-layer differentiation, a subset of which might be large and exhibited other atypical presentations, including two- or three-layer differentiation or even hematometra. Abnormally located ovaries are not rare.

KEY POINTS

• Morphologically, MRKH patients typically displayed bilateral uterine rudiments combined with a fibrous band. • Typically, the uterine rudiments (84.4%) were small and displayed only one-layer differentiation. • About 15.6% of rudiments showed atypical characteristics including two- or three-layer differentiation, even complicated with hematometra or hematosalpinx.

Uterus Transplantation as a Therapy Method in Mayer-Rokitansky-Küster-Hauser Syndrome

The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is the most common cause of uterine aplasia (underdevelopment or absence) at a frequency estimated to be worldwide of 1/4500 births of new-born female infants.

This is a literature review aiming to determine the sufficiency of the uterine transplantation (UTx) method as a therapeutic protocol for the MRKH syndrome.

Online searches were carried out in PubMed, Embase, CINAHL and Google scholar databases, during January and February 2019. The search included a combination of the various terms (see key words) as well as a combination of these terms in Greek and English so as to identify and display articles that would be as close as possible to the subject of research.

The online search yielded 95 articles. Eighty-five of these were considered as eligible and possible sources from the title and abstract presented but later were excluded, whereas 10 of them were selected to be included in the literature review. The literature review results showed that two therapeutic methods that are now successfully applied are the Vecchietti method and the Davydov method, which is the latest and less invasive technique but with equally if not improved immediate results. However, this treatment is not adequate to satisfy or provide a solution for the reproduction requirements of this patient group. The UTx proved sufficient.

Although uterus transplant could be considered the ideal solution for the management of infertility and the satisfaction of the reproductive and sexual needs of women with MRKH syndrome, since the first successful pregnancy after uterine transplantation is a reality in the recent years, it is early days to be considered as a safe mode of management.

Pelvic pain in patients with complex mullerian anomalies including Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH), obstructed hemi-vagina ipsilateral renal anomaly (OHVIRA), and complex cloaca

Caring for patients with congenital pelvic anomalies can be challenging in many ways but one crucial aspect is providing longitudinal into adulthood. Newborns with urinary, intestinal or vaginal obstruction require urgent operations to relieve obstruction followed by multiple reconstructive procedures involving the perineum. Openings are created in the pelvic floor musculature that did not exist in development. Adolescence presents further challenges for these postoperative patients while other diagnoses present for the first time in the peri-pubertal teenage years. Young adults can have new symptoms when they become sexually active and are faced with reproductive decisions. During all of these time periods, optimization of function is of paramount importance and patients who are suffering are not able to participate in school, sports or work. This study evaluates the prevalence of pelvic pain in newborns and adolescents with complex congenital pelvic anomalies, associated factors and possible treatment options.

A rare form of Mayer-Rokitansky-Küster-Hauser syndrome: Case report and review of literature

Introduction

Primary amenorrhea is failure to reach menarche. Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is the second most common cause of primary amenorrhea, after gonadal dysgenesis. Herein, we report a rare case of an unusual subtype of MRKH syndrome.

Case Report

This report describes the case of a 28-year-old woman with primary amenorrhea and coital difficulties. On examination, she had normal secondary sexual characteristics but a blind-ending vagina. Her hormonal profile was within normal limits; ultrasound examination was inconclusive due to technical difficulties. Subsequently, she underwent pelvic magnetic resonance imaging, which revealed bilateral rudimentary uterine horns in the presence of normal ovaries and normal length of a blind-ending narrow vagina.

Conclusion

MRKH syndrome with bilateral rudimentary uterine horns and normal-length vagina is an unusual form of Müllerian agenesis.

[Place of ultrasound in the management of Mayer-Rokitansky-Kuster-Hauser syndrome. Observational study from 2000 to 2017 within university hospital of Strasbourg]

OBJECTIVES

Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) is the most common cause of congenital absence or severe hypoplasia of structures derived from Muller's canals including the upper vagina, uterus and fallopian tubes. The definition of this syndrome is the presence of normal female secondary sexual development criteria relating to the presence of functional ovaries associated with vaginal agenesis and uterine anomalies ranging from a rudimentary uterus to the total absence of uterus. The main clinical sign of MRKH is primary amenorrhea. Confirmation of diagnosis and identification of associated abnormalities are based primarily on imaging and Magnetic Resonance Imaging (MRI) is currently the gold standard in the comprehensive evaluation of MRKH syndrome. Therefore, this study evaluated the place of ultrasound in the diagnostic and therapeutic management of patients treated for MRKH syndrome.

METHODS

This retrospective, single-center, observational study collected all patients in charge of diagnosis or treatment of MRKH Syndrome between January 2000 and June 2017 within the University Hospital Gynecology and Obstetrics Department of Strasbourg. The analysis of the medical files allowed the evaluation of ultrasound in the different stages of the patient's care.

RESULTS

Twenty-one patients were included and 81% get an ultrasound, 38% of them had a referred ultrasound performed by a certified radiologist. Forty-eight percent of the patients had an MRI and every ultrasound provided a correct diagnosis. Sixteen patients received therapeutic management and only 50% of patients had preoperative MRI.

CONCLUSION

The role of medical imaging is to define the extent of uterovaginal abnormalities for accurate diagnosis, describe any coexisting abnormalities, and provide a roadmap for surgical planning. The first-line examination is transabdominal ultrasound, a simple, non-invasive procedure. The use of MRI in our series did not bring any diagnostic surplus value. Despite the faster and easier access to MRI; ultrasound remains an indispensable tool in the diagnostic and therapeutic management of MRKH patients.

Spectrum of Type I and Type II Syndromes and Associated Malformations in Chinese Patients with Mayer-Rokitansky-Küster-Hauser Syndrome: A Retrospective Analysis of 274 Cases

STUDY OBJECTIVE

To analyze the spectrum of type I and type II malformations in Chinese patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This was a cross-sectional descriptive study that used data from a National Clinical Research Center for Obstetrical and Gynecological Diseases of China, reviewed from January 2009 to July 2017. Data of in- and outpatients with MRKH syndrome were reviewed and analyzed.

RESULTS

A total of 274 cases were included in the analysis: 197/274 (71.9%) with type I MRKH syndrome and the remaining 77/274 (28.1%) with type II MRKH syndrome. The rate of concurrent deformities was 32/244 (13.1%) for renal malformation, and 49/125 (39.2%) for skeletal malformation. Nine patients had renal and skeletal malformations (Müllerian duct aplasia, renal aplasia, and cervicothoracic somite dysplasia). Cardiac, neurologic, and other malformations (eg, anal atresia) were sporadic. The percentage of type II MRKH syndrome in our cohort was considerably higher than that reported 43/594 (7.2%) in a previous large-scale study in southern China, but lower than that 489/1259 (46.2%) reported for Caucasian individuals.

CONCLUSION

The spectrum of type I and type II MRKH syndrome varies across different races and geological locations.

Increased incidence of abnormally located ovary in patients with Mayer-Rokitansky-Küster-Hauser syndrome: a retrospective analysis with magnetic resonance imaging

PURPOSE

To explore the incidence of abnormally located ovary in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome as compared to a control group with magnetic resonance imaging.

METHODS

Pelvic MR images of 83 MRKH patients and 60 age-matched normal females were retrospectively reviewed by two experienced gynecological radiologists in consensus. Characteristics including location of ovary, ovarian volume, and follicle counts were assessed. The incidence of abnormally located ovary was compared between MRKH patients and controls. The ovarian size and follicle counts were compared among three groups: abnormally located ovaries in MRKH patients, eutopic ovaries in MRKH patients, and normal controls.

RESULTS

In total, 166 ovaries of 83 MRKH patients and 120 ovaries of 60 control females were evaluated. Thirty-seven ovaries of 23 MRKH patients (28%, 23/83) were abnormally located, whereas 3 ovaries of three control females (5%, 3/60) were located in abnormal positions (P < 0.001). The mean volume was 9.2 ± 6.3 mL of the abnormally located ovaries in MRKH patients, 7.8 ± 4.0 mL of the eutopic ovaries in MRKH patients, and 8.9 ± 4.8 mL in control females (P > 0.05). No obvious differences were observed with regard to follicle counts among the three groups.

CONCLUSION

Incidence of abnormally located ovary was significantly increased in patients with MRKH syndrome. Such knowledge is important for infertility treatment, evaluation of pelvic pain, and surgical planning for MRKH patients.

Adenocarcinoma arising in sigmoid colon neovagina 53 years after construction

Background

In view of the rarity of vaginal agenesis, malignancy arising in the neovagina is extremely rare.

Case presentation

Here, we report a 76-year-old female with an adenocarcinoma arising in the sigmoid colon neovagina which was constructed 53 years ago for congenital vaginal agenesis. Vaginal endoscopy to examine vaginal bleeding revealed a protruding lesion occupying three quarters of the lumen in the vicinity of anastomosis of the residual vagina and sigmoid colon. Transvaginal ultrasonography revealed the muscularis propria layer (hypoechoic fourth layer) to be interrupted. CT revealed no distant metastasis. Total pelvic exenteration was performed based on the diagnosis of neovaginal cancer at the anastomosis site. The 45-mm tumor showed well-differentiated adenocarcinoma with a mucinous adenocarcinoma component. Immunohistochemistry showed no p16-overexpressing tumor cells, suggesting the lack of human papilloma virus infection.

Conclusions

Although rare, clinicians should be aware of cancer that arises in the ectopic intestine when anastomosed with other organs.

Identification and functional analysis of a novel LHX1 mutation associated with congenital absence of the uterus and vagina

Congenital absence of the uterus and vagina (CAUV) is the most extreme female Müllerian duct abnormality. Several researches proposed that genetic factors contributed to this disorder, whereas the precise genetic mechanism is far from full elucidation. Here, utilizing whole-exome sequencing (WES), we identified one novel missense mutation in LHX1 (NM_005568: c.G1108A, p.A370T) in one of ten unrelated patients diagnosed with CAUV. This mutation was absent from public databases and our internal database. Through the luciferase reporter analysis, we found that the mutation could change the transcriptional activity of LHX1 and its effect on the regulation of the downstream target gene GSC, which might be associated with urogenital system development. In short, we concluded that the LHX1 may be a pathogenic gene of CAUV. Our results demonstrate the power of whole exome sequencing and gene prioritization approach as diagnostic tools in clinical practice that help make genetic diagnosis of CAUV.

Anatomic and Functional Outcomes of Paramesonephric Remnant-Supported Laparoscopic Double-Layer Peritoneal Pull-Down Vaginoplasty Technique in Patients with Mayer-Rokitansky-Küster-Hauser Syndrome: Uncu Modification

OBJECTIVE

To describe modifications to the double-layer peritoneal pull-down laparoscopic vaginoplasty technique (Davydov operation) and evaluate anatomic and functional outcomes of the new technique, known as the Uncu modification.

DESIGN

Case series (Canadian Task Force classification III).

SETTING

Tertiary care university hospital.

PATIENTS

Women with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) who underwent surgery between 2010 and 2016.

INTERVENTIONS

Laparoscopic double-layer peritoneal pull-down vaginoplasty with paramesonephric remnant support to the neovagina.

MEASUREMENTS AND MAIN RESULTS

Long-term anatomic and functional satisfaction results. Twenty-seven women with MRKHS underwent surgery with the Uncu-modified Davydov procedure. At 1 year after surgery, the mean vaginal length in these patients was 7.91 ± 1.4 cm. Among the 23 patients who had regular vaginal intercourse, the mean functional satisfaction score was 8.65 ± 1.2. One patient had a perioperative bladder injury, and another patient had a rectovaginal fistula at 3 months after the operation. One woman who did not comply with the prescribed postoperative mold exercises had complete closure of the introitus.

CONCLUSION

The Uncu modified laparoscopic double-layer peritoneal pull-down technique appears to be an effective and safe surgical management option that is easy to learn and perform by gynecologic surgeons.

Assessing the Experience of Vaginal Dilator Use and Potential Barriers to Ongoing Use among a Focus Group of Women with Mayer-Rokitansky-Küster-Hauser Syndrome

STUDY OBJECTIVE

To assess the experience of dilator use for neovagina creation in women diagnosed with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and identify barriers affecting patient compliance with dilator use.

DESIGN AND SETTING

This was a qualitative study using a structured questionnaire to investigate perception and identify barriers regarding vaginal dilator use. A questionnaire was administered after participants viewed a 2-minute patient educational video to additionally examine the usefulness of a patient education video tool as an adjunct to counseling in clinic on vaginal dilator use.

PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES

We enrolled 13 adolescent girls and women diagnosed with MRKH, aged 14-48 years, recruited from clinic and during a conference geared toward women affected by MRKH.

RESULTS

The mean age of participants was 26 (±11.4) years with most diagnosed between the ages of 12 and 18 years. Of all participants, 69% (9/13) reported ever being sexually active with a mean age of coitarche of 16 (±2.6) years. Seventy-seven percent (10/13) reported current or past use of vaginal dilators, and most had some previous education on dilator use. Only 15% (2/13) reported no previous exposure to an educational tool. After viewing the 2-minute educational video, all participants rated it very helpful using a Likert scale (strongly agree to strongly disagree). Major themes that emerged as perceived barriers to dilator use included viewing dilation as a negative experience, uncertainty about success, and lack of motivation.

CONCLUSION

Education is an integral part of improving compliance with vaginal dilator use among adolescent girls and women affected by MRKH. Technology can be used to reinforce face-to-face counseling in the clinic. To our knowledge, this is the first study to specifically investigate patient experience with dilator use and opinion regarding the use of video technology to demonstrate self-directed neovagina creation in an MRKH population. The barriers identified in this study provide new insights to inform future research and clinical management of dilator use.

Evaluation of Mayer-Rokitansky-Küster-Hauser syndrome with magnetic resonance imaging: Three patterns of uterine remnants and related anatomical features and clinical settings

OBJECTIVE

To characterize the anatomical features and clinical settings of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and correlate them with patterns of uterine involvement.

METHODS

Pelvic magnetic resonance images and medical records of 92 MRKH patients were retrospectively reviewed. Patients were subgrouped by uterine morphology: uterine agenesis, unilateral rudimentary uterus and bilateral rudimentary uteri. Uterine volume, presence of endometrium, location of ovary, endometriosis and pelvic pain were compared among groups.

RESULTS

The mean uterine volume was 33.5 ml (17.5-90.0 ml) for unilateral uterine remnants, and 16.1 ml (3.5-21.5 ml) for bilateral uterine rudiments (p<0.01). The incidence of presence of endometrium (100% vs. 22%, p<0.001), haematometra (56% vs. 3%, p<0.001) and ovarian endometriosis (22% vs. 3%, p<0.01) was significantly increased in the group of unilateral rudimentary uteri as compared with the group of bilateral uterine remnants. Thirty-one patients (38%) showed ectopic ovaries. Pelvic pain was more common in individuals with unilateral rudimentary uterus than those who had no (56% vs. 5%, p<0.01) or bilateral uterine remnants (56% vs. 14%, p<0.05).

CONCLUSION

MRKH patients with different patterns of uterine involvement may have differentiated anatomical features and clinical settings.

KEY POINTS

• Rudimentary uteri, especially bilateral rudimentary uteri, were quite common in MRKH syndrome. • Uterine remnants can be relatively large, especially the unilateral rudimentary uterus. • Presence of endometrium and related complications are not rare in MRKH syndrome. • Existence of endometrium and complications are more frequent in unilateral rudimentary uterus.

Mclndoe Neovagina in patients with Mullerian Agenesis: A single center experience

Objectives:

To evaluate the surgical feasibility and the long-term anatomical and functional results and complication rates in patients with Mullerian aplasia who underwent vaginal reconstruction.

Methods:

A retrospective observational case series study over 8 years was conducted in King Faisal Specialist Hospital & Research Centre – Jeddah, Saudi Arabia. All cases diagnosed as Mullerian aplasia and who underwent surgical correction were included. Painless and satisfactory vaginal intercourse after surgery were the main outcome measured.

Results:

A total of 19 patients were diagnosed with Mullerian agenesis and underwent vaginal reconstruction by Mclndoe technique with minor modification. All of our patients who were sexually active and were compliant with mold use postoperatively were able to achieve 100% painless and satisfactory sexual intercourse.

Conclusions:

Minor modification in McIndoe technique provides easier, safer and deeper dissection that minimizes the complications and helps in maximizing the vaginal length. It provides satisfactory and functional vagina in the majority of the patients.

Vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association with Mayer-Rokitansky-Küster-Hauser syndrome in co-occurrence: two case reports and a review of the literature

BACKGROUND

The vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome are rare conditions. We aimed to present two cases with the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser co-occurrence from our local surgical center and through a systematic literature search detect published cases. Furthermore, we aimed to collect existing knowledge in the embryopathogenesis and genetics in order to discuss a possible link between the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome.

CASE PRESENTATION

Our first case was a white girl delivered by caesarean section at 37 weeks of gestation; our second case was a white girl born at a gestational age of 40 weeks. A co-occurrence of vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome was diagnosed in both cases. We performed a systematic literature search in PubMed ((VACTERL) OR (VATER)) AND ((MRKH) OR (Mayer-Rokitansky-Küster-Hauser) OR (mullerian agenesis) OR (mullerian aplasia) OR (MURCS)) without limitations. A similar search was performed in Embase and the Cochrane library. We added two cases from our local center. All cases (n = 9) presented with anal atresia and renal defect. Vertebral defects were present in eight patients. Rectovestibular fistula was confirmed in seven patients. Along with the uterovaginal agenesis, fallopian tube aplasia appeared in five of nine cases and in two cases ovarian involvement also existed.

CONCLUSIONS

The co-occurrence of the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome is extremely rare. This group of patients has unusual phenotypic characteristics. The long-term outcome after treatment of defects is not well reported. A single unifying cause is not known and the etiology probably includes both genetic and non-genetic causes. We stress the importance of future studies to optimized treatment, follow-up, and etiology.

Uterine Tissue Engineering and the Future of Uterus Transplantation

The recent successful births following live donor uterus transplantation are proof-of-concept that absolute uterine factor infertility is a treatable condition which affects several hundred thousand infertile women world-wide due to a dysfunctional uterus. This strategy also provides an alternative to gestational surrogate motherhood which is not practiced in most countries due to ethical, religious or legal reasons. The live donor surgery involved in uterus transplantation takes more than 10 h and is then followed by years of immunosuppressive medication to prevent uterine rejection. Immunosuppression is associated with significant adverse side effects, including nephrotoxicity, increased risk of serious infections, and diabetes. Thus, the development of alternative approaches to treat absolute uterine factor infertility would be desirable. This review discusses tissue engineering principles in general, but also details strategies on how to create a bioengineered uterus that could be used for transplantation, without risky donor surgery and any need for immunosuppression. We discuss scaffolds derived from decellularized organs/tissues which may be recellularized using various types of autologous somatic/stem cells, in particular for uterine tissue engineering. It further highlights the hurdles that lay ahead in developing an alternative to an allogeneic source for uterus transplantation.
