Heterozygous ZNHIT3 variants within the 17q12 recurrent deletion region are associated with Mayer-Rokitansky-Kuster Hauser (MRKH) syndrome. Mol Cell Endocrinol 2024; 589:112237.

Abstract
The molecular basis of mullerian aplasia, also known as Mayer-Rokitansky-Kuster Hauser (MRKH) or congenital absence of the uterus and vagina, is largely unknown. We applied a multifaceted genetic approach to studying the pathogenesis of MRKH including exome sequencing of trios and duos, genome sequencing of families, qPCR, RT-PCR, and Sanger sequencing to detect intragenic deletions, insertions, splice variants, single nucleotide variants, and rearrangements in 132 persons with MRKH. We identified two heterozygous variants in ZNHIT3 localized to a commonly involved CNV region at chromosome 17q12 in two different families with MRKH. One is a frameshift, truncating variant that is predicted to interfere with steroid hormone binding of the LxxLL sequence of the C-terminal region. The second variant is a double missense/stopgain variant. Both variants impair protein expression in vitro. In addition, four more probands with MRKH harbored the stopgain variant without the nearby missense variant. In total, 6/132 (4.5%) of patients studied, including five with associated anomalies (type 2 MRKH), had ZNHIT3 variants that impair function in vitro. Our findings implicate ZNHIT3 as an important gene associated with MRKH within the 17q12 CNV region.

Abstract
OBJECTIVE This study aimed to describe the clinical features, associated extragenital anomalies, and management of Mayer- Rokitansky-Küster-Hauser (MRKH) syndrome in a Thai population. METHODS This retrospective study analyzed the medical records of 96 patients with MRKH syndrome diagnosed and treated at a university hospital and tertiary referral center in southern Thailand between 2000 and 2022. RESULTS The study included 96 patients with MRKH syndrome. The most common symptom was primary amenorrhea (88.5%), followed by difficulty or inability to engage in sexual intercourse (9.4%) and pelvic mass (2.1%). Notably, 80.3% of the patients did not have extragenital malformations and were diagnosed with MRKH type I (typical form), whereas 19.7% were categorized as MRKH type II (atypical form). Skeletal malformations were the most frequent extragenital anomalies and were present in 19.5% of patients, with scoliosis being the most common skeletal condition. Other extragenital malformations included renal (8.5%) and neurological (1.0%) abnormalities. Clinical vaginal examination revealed complete atresia in 21.8% and vaginal hypoplasia (median vaginal length, 3 cm) in 78.2% of the patients. Half of the patients did not receive treatment because they had not engaged in sexual intercourse. In this cohort, 41.7% of the patients had no difficulty performing sexual intercourse. Hence, self-dilation therapy or concomitant dilation was recommended. Only eight patients (8.3%) underwent surgical reconstruction of the vagina. CONCLUSION This study confirmed the complexity and heterogeneity of the phenotypic manifestations of MRKH, including the degree of vaginal atresia and types and rates of associated malformations.

Abstract
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.

Abstract
A case report of a premenarcheal patient with ovarian torsion and mullerian agenesis is presented. A 12-year-old prepubertal girl is presented with severe right lower quadrant abdominal pain and mild rebound. Laparoscopy showed mullerian agenesis and twisted right adnexa. Detorsion and cystectomy of the right ovary were done, and the ovary was fixed to the pelvic sidewall. The postoperative course was uneventful. An association between the lax attachment of the adnexa and torsion may be a contributing factor in this condition.

Abstract
The Mayer-Rokitansky-Küster-Hauser syndrome is characterized by aplasia of the uterus and upper two-thirds of the vagina. While it can appear as an isolated genital malformation, it is often associated with extragenital abnormalities, with little still known about the pathogenetic background. To provide an overview of associated malformations and syndromes as well as to examine possible ties between the rudimentary tissue and patient characteristics, we analyzed a cohort of 469 patients with MRKHS as well as 298 uterine rudiments removed during surgery. A total of 165 of our patients (35.2%) had associated malformations (MRKHS type II). Renal defects were the most common associated malformation followed by skeletal abnormalities. Several patients had atypical associated malformations or combined syndromes. Uterine rudiments were rarer in patients with associated malformations than in patients without them. Rudiment size ranged from 0.3 cm3 to 184.3 cm3 with a mean value of 7.9 cm3. Importantly, MRKHS subtype or concomitant malformations were associated with a different frequency of uterine tissue as well as a different rudiment size and incidence of endometrial tissue, thereby indicating a clear heterogeneity of the phenotype. Further research into the associated molecular pathways and potential differences between MRKHS subtypes is needed.

Abstract
Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is characterized by aplasia of the female reproductive tract; the syndrome can include renal anomalies, absence or dysgenesis, and skeletal anomalies. While functional models have elucidated several candidate genes, only WNT4 (MIM: 603490) variants have been definitively associated with a subtype of MRKH with hyperandrogenism (MIM: 158330). DNA from 148 clinically diagnosed MRKH probands across 144 unrelated families and available family members from North America, Europe, and South America were exome sequenced (ES) and by family-based genomics analyzed for rare likely deleterious variants. A replication cohort consisting of 442 Han Chinese individuals with MRKH was used to further reproduce GREB1L findings in diverse genetic backgrounds. Proband and OMIM phenotypes annotated using the Human Phenotype Ontology were analyzed to quantitatively delineate the phenotypic spectrum associated with GREB1L variant alleles found in our MRKH cohort and those previously published. This study reports 18 novel GREB1L variant alleles, 16 within a multiethnic MRKH cohort and two within a congenital scoliosis cohort. Cohort-wide analyses for a burden of rare variants within a single gene identified likely damaging variants in GREB1L (MIM: 617782), a known disease gene for renal hypoplasia and uterine abnormalities (MIM: 617805), in 16 of 590 MRKH probands. GREB1L variant alleles, including a CNV null allele, were found in 8 MRKH type 1 probands and 8 MRKH type II probands. This study used quantitative phenotypic analyses in a worldwide multiethnic cohort to identify and strengthen the association of GREB1L to isolated uterine agenesis (MRKH type I) and syndromic MRKH type II.

Abstract
The molecular basis of Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome remains largely unknown. Pathogenic variants in WNT4 and HNF1B have been confirmed in a small percent of individuals. A variety of copy number variants have been reported, but causal gene(s) remain to be identified. We hypothesized that rare structural variants (SVs) would be present in some individuals with MRKH, which could explain the genetic basis of the syndrome. Large molecular weight DNA was extracted from lymphoblastoid cells from 87 individuals with MRKH and available parents. Optical genome mapping (OGM) was performed to identify SVs, which were confirmed by another method (quantitative PCR, chromosomal microarray, karyotype, or fluorescent in situ hybridization) when possible. Thirty-four SVs that overlapped coding regions of genes with potential involvement in MRKH were identified, 14 of which were confirmed by a second method. These 14 SVs were present in 17/87 (19.5%) of probands with MRKH and included seven deletions, three duplications, one new translocation in 5/50 cells-t(7;14)(q32;q32), confirmation of a previously identified translocation-t(3;16)(p22.3;p13.3), and two aneuploidies. Of interest, three cases of mosaicism (3.4% of probands) were identified-25% mosaicism for trisomy 12, 45,X(75%)/46,XX (25%), and 10% mosaicism for a 7;14 translocation. Our study constitutes the first systematic investigation of SVs by OGM in individuals with MRKH. We propose that OGM is a promising method that enables a comprehensive investigation of a variety of SVs in a single assay including cryptic translocations and mosaic aneuploidies. These observations suggest that mosaicism could play a role in the genesis of MRKH.

Abstract
INTRODUCTION Uterus transplantation introduces unique challenges regarding immunosuppression, including the effects of immunosuppressive drugs on the fetus and graft rejection during pregnancy. Although immunosuppressive regimens are based on protocols used after solid organ transplantation, in recipients of uterus grafts, the physician must consider therapy modifications based on the phase of the transplant, from the intra-operative period through to delivery. AREAS COVERED This review discusses the current immunosuppressive rationale in uterus transplantation, focusing on the therapy in each phase of the transplant. The authors present an overview of the already approved immunosuppressive medications for solid organ transplantation, their application in uterus transplant prior to pregnancy, during pregnancy and as rejection treatment. EXPERT OPINION Most medications used for uterus transplant are adopted from solid organ transplantation experience, especially kidney transplantation, and rejection is treated in standard fashion. Research is needed to clarify the drugs' effects on fetal and neonatal well-being and to develop new medications to achieve better tolerance. Early markers of uterus graft rejection need to be identified, and prior rejection episodes should no longer be a cause to remove the graft during delivery in a recipient who wants a further pregnancy.

Abstract
This review presents an update of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome on its etiologic, clinical, diagnostic, psychological, therapeutic, and reproductive aspects. The etiology of MRKH syndrome remains unclear due to its intrinsic heterogeneity. Nongenetic and genetic causes that may interact during the embryonic development have been proposed with no definitive etiopathogenesis identified. The proportion of concomitant extragenital malformations varies in different studies, and the discrepancies may be explained by ethnic differences. In addition to physical examination and pelvic ultrasound, the performance of pelvic magnetic resonance imaging is crucial in detecting the presence of rudimentary uterine endometrium. MRKH syndrome has long-lasting psychological effects on patients, resulting in low esteem, poor coping strategies, depression, and anxiety symptoms. Providing psychological counseling and peer support to diagnosed patients is recommended. Proper and timely psychological intervention could significantly improve a patient's outcome. Various nonsurgical and surgical methods have been suggested for treatment of MRKH syndrome. Due to the high success rate and minimal risk of complications, vaginal dilation has been proven to be the first-line therapy. Vaginoplasty is the second-line option for patients experiencing dilation failure. Uterine transplantation and gestational surrogacy are options for women with MRKH syndrome to achieve biological motherhood.

[PMID: 36388626 PMCID: PMC9659481 DOI: 10.2147/jmdh.s386936] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 10/25/2022] [Indexed: 11/11/2022] Open
Abstract
Objective To describe variable mullerian duct anomalies using magnetic resonance imaging (MRI) and to classify these anomalies according to the available classification systems, namely the American Fertility Society (AFS) system, the European Society of Human Reproduction and Embryology (ESHRE) system, and the new American Society for Reproductive Medicine (ASRM) system. Design Retrospective chart review. Subjects The pelvic MRI studies and the clinical records of 64 females with mullerian congenital anomalies were retrospectively reviewed between January 2010 and December 2021. The mean age was 22 years (age range 2–63 years). Main Outcome Measures Detailed imaging findings were recorded, and the resulting mullerian anomalies were then classified according to the three classification systems of interest. Results Variable mullerian anomalies were found among patients with multiple frequencies. Mullerian agenesis and hypoplasia were found in 12 patients (19%) and 16 patients (25%), respectively. Uterus didelphys was found in 5 patients (8%). Twelve (19%) patients had septate uterus, while 8 (12.5%) had a bicornuate anomaly. Unicornuate uterus was present in 7 patients (11%). Isolated vaginal anomaly was diagnosed in 4 patients (6%). Renal/urinary tract imaging was available for 27 (42%) patients, and accompanying urinary tract anomalies were noted in 10 of them (37%). Few ovarian and other extra-renal anomalies were observed. Conclusion MRI could efficiently delineate the mullerian anomalies regardless of their complexity. Most of these anomalies were more efficaciously categorized by the ESHRE and the new ASRM systems, compared to the originally widely used AFS system. The new ASRM classification was found to be more practical as it is a modification of the original AFS system, using drawings with clear descriptions instead of symbols. This is particularly helpful in the radiological era, saving time and effort.

Endometriosis in Patients with Mayer-Rokitansky-Küster-Hauser-Syndrome—Histological Evaluation of Uterus Remnants and Peritoneal Lesions and Comparison to Samples from Endometriosis Patients without Mullerian Anomaly. J Clin Med 2022; 11:jcm11216458. [DOI: 10.3390/jcm11216458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 10/24/2022] [Accepted: 10/26/2022] [Indexed: 11/06/2022] Open
Abstract
Congenital Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a Mullerian-duct anomaly that is characterized by agenesis of the uterus and upper part of the vagina. Uterus remnants of varying sizes can often be found. Although a functional uterus is missing, the existence of endometriosis in this patient group has been described in the literature; however, a histopathological comparison of the characteristics of the endometrium within the uterus remnants versus endometriotic peritoneal lesions in the same patient is lacking. Moreover, the characteristics of endometriotic tissue in patients with MRKH syndrome have not been correlated with those of patients with endometriosis without Mullerian anomaly. Patients who underwent laparoscopic neovagina creation with the removal of uterus remnants and possible resection of endometriotic lesions between 2010 and 2022 at the Department of Women’s health of the University of Tuebingen were included in our study. Uterine remnants and endometriotic tissue were evaluated via histopathology and immunohistochemistry and were compared to endometriotic samples from patients without Mullerian anomaly. Endometriosis was detected in nine MRKH patients; in four patients, endometrial remnants could be sufficiently compared to endometriotic lesions. All samples exhibited increased expression of hormonal receptors. In two patients, Ki67 proliferation index was significantly increased in peritoneal endometriotic lesions compared with the endometrium of the remnants. In contrast, endometrium and endometriotic lesions of endometriosis patients did not exhibit any differences in the Ki67 proliferation index. Our results demonstrate distinctive immunohistochemical variability between uterine remnants and endometriotic lesions in patients with MRKH syndrome compared with patients with endometriosis, indicating a possible explanation model of the yet-unknown etiology of endometriosis. For confirmation, investigation of a broader patient collective is necessary.

Abstract
Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is the second most common cause of primary amenorrhea with an incidence of 1:4000–5000 women. It is characterized by aplasia or hypoplasia of the uterus and the upper two-thirds of the vagina with normal ovaries and tubes and a normal secondary sexual characteristics. The occurrence of leiomyoma is common but it is rare to have leiomyoma in uterine remnant in MRKH syndrome. Although few cases of MRKH syndrome with leiomyoma have been reported in the literature, none presented with urinary retention. Here, we report a case of 28-year-old women who presented with urinary retention that unmasked deeply embedded huge fibroids in pelvis arising from a rudimentary uterine horns and its safe management via laparoscopic approach.

Abstract
The uterus is responsible for the nourishment and mechanical protection of the developing embryo and fetus and is an essential part in mammalian reproduction. Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is characterized by agenesis of the uterus and upper part of the vagina in females with normal ovarian function. Although heavily studied, the cause of the disease is still enigmatic. Current research in the field of MRKH mainly focuses on DNA-sequencing efforts and, so far, has been unable to decipher the nature and heterogeneity of the disease, thereby holding back scientific and clinical progress. Here, we developed long-term expandable organoid cultures from endometrium found in uterine rudiment horns of MRKH patients. Phenotypically, they share great similarity with healthy control organoids and are surprisingly fully hormone responsive. Transcriptome analyses, however, identified an array of dysregulated genes that point to potentially disease-causing pathways altered during the development of the female reproductive tract. We consider the endometrial organoid cultures to be a powerful research tool that promise to enable an array of studies into the pathogenic origins of MRKH syndrome and possible treatment opportunities to improve patient quality of life.

Abstract
Uterus transplantation (UTx) provides a new pathway to parenthood for patients with absolute uterine factor infertility. The application of reproductive technologies, such as in vitro fertilization, embryo cryopreservation, and frozen embryo transfers, for this unique population, is particularly nuanced and continually evolving. There are important pretransplant and posttransplant reproductive considerations for physicians and patients anticipating UTx. As with any rapidly evolving medical innovation, efforts to consolidate experiences and knowledge by centers offering UTx is paramount.

Abstract
Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by congenital absence of both the uterus and vagina. Some patients require surgery to create a neovagina, however, the preservation of a nonfunctional rudimentary uterus after surgery may lead to long-term complications. Herein, a rare case of a giant hysteromyoma after vaginoplasty, in a 31-year-old Chinese female patient who was diagnosed with MRKH syndrome, is reported. The patient, who had undergone vaginal reconstruction 4 years previously, presented with abdominal distension for the previous 2 weeks. Transabdominal ultrasonography showed a firm mass of approximately 10 × 10 cm in the lower abdomen. The patient subsequently underwent an exploratory laparotomy, and a leiomyoma from her rudimentary uterus was removed. Beside this case, seven cases, published between 2004 and 2020, were identified during a literature search. Findings of the present and previously published cases suggest that gynaecologists should pay particular attention to the risks of pelvic complications in female patients with MRKH syndrome who have previously undergone surgery, and select appropriate therapeutic methods.

Abstract
Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) or Müllerian agenesis represents uterovaginal aplasia or hypoplasia of unknown aetiology in young women with usual 46,XX karyotype and normal secondary sexual characteristics. We report a 15-year-old female patient who presented to a specialised diabetes endocrine and metabolism centre in Basrah, Iraq, in 2019 with primary amenorrhoea and normal pubertal secondary sexual characteristics, hormonal workup and clinical examination. Abdominopelvic magnetic resonance imaging (MRI) revealed cervical and uterine agenesis with the absence of the proximal thirds of the vagina. Both kidneys were fused in the right iliac fossa with oval lobulated appearance and crossed fused ectopia. The ovaries were normal and located bilaterally. The diagnosis of MRKHS type 2 was confirmed based on clinical, biochemical and radiological findings. The correct clinical and radiological diagnosis of MRKHS by MRI is crucial for long-term management.

Abstract
There are many proposed classification systems for müllerian anomalies. The American Fertility Society (AFS) Classification from 1988 has been the most recognized and utilized. The advantages of this iconic classification include its simplicity, recognizability, and correlation with clinical pregnancy outcomes. However, the AFS classification has been criticized for its focus primarily on uterine anomalies, with exclusion of those of the vagina and cervix, its lack of clear diagnostic criteria, and its inability to classify complex aberrations. Despite this classification and others, the wide range of müllerian anomalies is still largely unknown and confusing to many providers. Consequently, müllerian anomalies may go undiagnosed for extended periods, receive inappropriate or inadequate surgical interventions, and result in persistent issues such as pain or loss of reproductive function. The American Society for Reproductive Medicine Task Force on Müllerian Anomalies Classification was formed and charged with designing a new classification. The Task Force set goals for a new classification and chose to base it on the iconic AFS classification from 1988 because of its simplicity and recognizability, while expanding and updating it to include all categories of anomalies. In addition, this was recognized as an opportunity to raise awareness of this area of medicine, educate providers and learners, and promote patient advocacy. Presented here is the new American Society for Reproductive Medicine Müllerian Anomalies Classification 2021.

Abstract
STUDY OBJECTIVE Müllerian (paramesonephric) duct anomalies (MDAs) are associated with several coexisting congenital abnormalities, including renal abnormalities. Although congenital renal abnormalities may remain asymptomatic, the consequences should not be underestimated. In both the literature and clinical practice, it remains necessary to improve awareness of the co-occurrence of different congenital renal abnormalities in women with MDAs. To gain further insight into this co-occurrence and to estimate whether guidelines for women with MDAs should be optimized, this study was performed. DESIGN A descriptive retrospective analysis. SETTING University Medical Centre Utrecht in the Netherlands. PARTICIPANTS Women with MDAs diagnosed or treated between 1980 and 2015. INTERVENTIONS None. MAIN OUTCOME MEASURES The prevalence of the co-occurrence of congenital renal abnormalities in women with MDAs. RESULTS Renal status was recorded in 186 of 255 women (72.9%), and the other women (27.1%) did not have a retrievable renal status. Congenital renal abnormalities were present in 90 of 186 women (48.4%) and were observed most frequently in women having a duplex uterus with obstructed hemivagina. The most common renal abnormality was unilateral renal agenesis, which was observed in 58 of 90 women (64.4%). CONCLUSIONS MDAs are highly associated with different congenital renal abnormalities, and these results emphasize that women with MDAs should be routinely screened for their co-occurrence. However, these results also highlight that there remains a lack of awareness of this association. Whether all women with congenital renal abnormalities should be routinely screened for MDAs requires further investigation.

Prevalence of urinary, prolapse, and bowel symptoms in Mayer-Rokitansky-Küster-Hauser syndrome. Am J Obstet Gynecol 2021; 225:70.e1-70.e12.

Abstract
BACKGROUND Müllerian agenesis, or Mayer-Rokitansky-Küster-Hauser syndrome, occurs in 1 in 4500 to 5000 individuals assigned female sex at birth. Pelvic floor symptoms among individuals with Mayer-Rokitansky-Küster-Hauser syndrome have not been well studied, and it is unknown how vaginal lengthening treatments affect these symptoms. OBJECTIVE This study aimed to assess urinary, prolapse, and bowel symptoms in individuals with Mayer-Rokitansky-Küster-Hauser syndrome and to determine whether symptoms vary by vaginal lengthening treatment. STUDY DESIGN We conducted a cross-sectional study in 2019 using an online survey distributed by the Beautiful You MRKH Foundation via social media to individuals with Mayer-Rokitansky-Küster-Hauser syndrome. Demographics, age at and timing of diagnosis, information about vaginal lengthening treatment, urinary symptoms (Michigan Incontinence Symptom Index), prolapse symptoms (Pelvic Organ Prolapse Distress Inventory short-form version), and bowel symptoms (Bristol Stool Form Scale) were obtained. The inclusion criteria included self-reported diagnosis of müllerian agenesis and female sex. Respondents with a history of renal transplant or dialysis, completion of <85% of the survey, and non-English survey responses were excluded. Descriptive analyses were used to describe the sample population. Logistic regression, Kruskal-Wallis, and Fisher exact tests were used to compare the prevalence of pelvic floor symptoms and vaginal lengthening treatments. Associations between age and genitourinary symptoms were investigated with Spearman correlations. RESULTS Of 808 respondents, 615 met the inclusion criteria, representing 40 countries. 81% of respondents identified as white. The median age of the participants was 29 years (interquartile range, 24-36), with a median age at diagnosis of 16 years (interquartile range, 15-17). Among the 614 respondents, 331 (54%) had vaginal lengthening treatment, 130 of whom (39%) had undergone surgical vaginal lengthening. Of individuals with Mayer-Rokitansky-Küster-Hauser syndrome, 428 of 614 (70%) reported having had one or more urinary symptoms, and 339 of 428 (79%) reported being bothered by these symptoms. Urinary symptoms included urinary incontinence (210 of 614 [34%]), urinary frequency (245 of 614 [40%]), urinary urgency (248 of 614 [40%]), pain with urination (97 of 614 [16%]), and recurrent urinary tract infections (177 of 614 [29%]). Prolapse symptoms included lower abdominal pressure (248 of 612 [41%]), pelvic heaviness or dullness (177 of 610 [29%]), and vaginal bulge (68 of 609 [11%]). In addition, constipation was reported by 153 of 611 respondents (25%), and anal incontinence was reported by 153 of 608 (25%) respondents. Beside recent urinary incontinence (P=.003) and anal incontinence (P<.001), the prevalence of pelvic floor symptoms (P>.05) did not differ significantly between those with and without vaginal lengthening. Among those with surgical vaginal lengthening, symptomatic vaginal bulge was highest in individuals who underwent a bowel vaginoplasty procedure. CONCLUSION Urinary, prolapse, and bowel symptoms are common among individuals with Mayer-Rokitansky-Küster-Hauser syndrome and should be evaluated in this population. Overall, compared with no vaginal lengthening treatment, having vaginal lengthening treatment is not associated with substantial differences in the prevalence of pelvic floor symptoms, with the exception of recent urinary incontinence and anal incontinence. Our data suggested that bowel vaginoplasty may be associated with greater symptoms of vaginal bulge. More robust studies are needed to determine the impact of various vaginal lengthening treatments on pelvic floor symptoms.

Abstract
Müllerian duct anomalies (MDAs) are developmental disorders of the Müllerian duct, the embryonic anlage of most of the female reproductive tract. The prevalence of MDAs is 6.7% in the general female population and 16.7% in women who exhibit recurrent miscarriages. Individuals affected by these anomalies suffer from high rates of infertility, first-trimester pregnancy losses, premature labour, placental retention, foetal growth retardation and foetal malpresentations. The aetiology of MDAs is complex and heterogeneous, displaying a range of clinical pictures that generally lack a direct genotype-phenotype correlation. De novo and familial cases sharing the same genomic lesions have been reported. The familial cases follow an autosomal-dominant inheritance, with reduced penetrance and variable expressivity. Furthermore, few genetic factors and molecular pathways underpinning Müllerian development and dysregulations causing MDAs have been identified. The current knowledge in this field predominantly derives from loss-of-function experiments in mouse and chicken models, as well as from human genetic association studies using traditional approaches, such as microarrays and Sanger sequencing, limiting the discovery of causal factors to few genetic entities from the coding genome. In this Review, we summarise the current state of the field, discuss limitations in the number of studies and patient samples that have stalled progress, and review how the development of new technologies provides a unique opportunity to overcome these limitations. Furthermore, we discuss how these new technologies can improve functional validation of potential causative alterations in MDAs. Summary: Here, we review the current knowledge about Müllerian duct anomalies in the context of new high-throughput technologies and model systems and their implications in the prevention of these disorders.

Abstract
The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder caused by the abnormal absence of paramesonephric ducts. The main characteristics of this syndrome include hypoplasia or aplasia of the uterus, absence of the cervix and upper part of vagina. Otherwise, ovaries and fallopian tubes have normal functions. A 9-year-old girl presented to the emergency department by acute abdominal pain. Based on a high probable diagnosis of ovarian torsion, surgical exploration was accomplished demonstrating rudimentary or aplastic uterus, hypoplasia of the left adnexa and torsion of the right ovary. In consideration of MRKH syndrome, further assessments were done and the diagnosis was confirmed. As this syndrome is rare and there is a probability of ovarian torsion caused by malformation of the ovarian ligament, physicians should be aware of this syndrome to diagnose it earlier and preserve the ovarian tissue.

Abstract
OBJECTIVE To reveal the proportion of concomitant extragenital malformations in a large cohort of Chinese patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. STUDY DESIGN Retrospective study. SETTING Tertiary teaching hospitals in China. PATIENT(S) A total of 1,055 Chinese Han women with MRKH syndrome diagnosed and treated at 11 Chinese tertiary teaching hospitals from January 2015 to January 2020. INTERVENTION(S) Karyotype analysis, hormone profiling, pelvic ultrasonography, spinal roentgenograms, urologic ultrasonography, and Chinese female reproductive tract malformation registry platform (https://ecrf.linklab.com/). MAIN OUTCOME MEASURE(S) Patients' demographic and clinical characteristics, concurrent malformations, and family histories. RESULT(S) Of the 1,055 Chinese Han patients with MRKH, 69.6% had type I MRKH syndrome and the remaining 30.4% had type II MRKH syndrome. Among the type II patients, 12.6% had müllerian duct aplasia, unilateral renal aplasia/ectopic kidney, and cervicothoracic somite dysplasia association. Skeletal malformations were the most common associated extragenital malformations in the study (22.0%, 232/1,055), of which idiopathic scoliosis and congenital vertebral malformations were the 2 main skeletal malformations (80.6% and 14.2%, respectively). Renal malformations were the second-highest associated extragenital malformations (9.7%, 102/1,055), with unilateral renal agenesis and ectopic kidney being the most common renal malformations (48.0% and 22.5%, respectively). CONCLUSION(S) Type II disease was less common among Chinese patients with MRKH syndrome compared with European patients. Skeletal malformations were more common extragenital malformations than renal malformations in our cohort.

Abstract
Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome can be treated through numerous surgical and nonsurgical methods. We present a surgical technique in which a neovagina was reconstructed and shaped by a vaginal expander with acellular porcine dermal matrix (XCM Biologic Tissue Matrix) and mucosal interposition using microfragments harvested from the hymen. In our case, we found this procedure to be safe and effective, resulting in satisfactory sexual function and good cosmetic results, without donor site morbidity. To our best knowledge, this tissue-engineered biomaterial has never been used for vaginal reconstruction before.

Abstract
Vaginal agenesis is a complex pediatric condition that lead to long-term urinary, gastrointestinal, and sexual dysfunction. A meticulous physical examination and in-depth diagnostic investigations are necessary to determine the appropriate surgical management. Reconstruction of neovagina can be retrieved from the ileum.
Vaginal agenesis with anorectal malformations is a complex pediatric condition that adversely affects various physiological processes in the body. It may cause disturbances in defecation and urination, abnormalities in the urinary and gastrointestinal tract, dysfunction of the genital and reproductive organs, and sexual function disorders. The complexity in the surgical management of vaginal agenesis includes the selection of a functional reconstruction technique for anal and vaginal formation, timing of the reconstruction, and management of complications in the associated organ system. Herein, we describe a patient with Mayer–Rokitansky–Küster–Hauser syndrome accompanied by a rectovesical fistula. Other abnormalities, such as microcephaly, polydactyly, long urethral abnormalities resembling the male urethra, and complications in the kidney and urinary tract, were observed in the patient. The associated complications included recurrent urinary tract infections, urinary overflow incontinence, vesicoureteric reflux, hydroureter, and left renal hydronephrosis. The patient underwent posterior sagittal anorectoplasty surgery and vaginal reconstruction. The long-term vaginal physiological development of patients with this condition remains unknown.

Abstract
Background. There is still no standardized treatment for vaginal agenesis; surgical repair using a minimally invasive technique is a good option, as it offers rapid results along with a fast postoperative recovery. Objective. To describe a new modified Vecchietti procedure by a mini-laparoscopic approach with intraoperative use of indocyanine green fluorescence technology for the creation of a neovagina in the setting of congenital vaginal agenesis. Methods. Retrospective review of all cases of congenital vaginal agenesis submitted to a mini-laparoscopic modified Vecchietti procedure with intraoperative use of indocyanine green (ICG) fluorescence (between June and September 2019). Patient relevant medical history, surgical technique, postoperative care, outcomes, and complications are described. Results. Four patients with Mayer-Rokitansky-Küster-Hauser syndrome (mean age: 19 years; mean preoperative vaginal length: 1.5 cm) were included in the study. The procedure was completed successfully and uneventfully in all patients. External traction device was removed 5-7 days after surgery and replaced by external vaginal silicone dilators. This technique was able to create 10-11 cm neovaginas in 1 week; six weeks after surgery all patients had an epithelized 10.5-12 cm length and 2.5-3 cm diameter neovagina. Complications consisted of one case of isolated fever at the ninth postoperative day, solved with empiric antibiotic treatment. Conclusion. The mini-laparoscopic modified Vecchietti approach, associated with ICG fluorescence imaging, is feasible and effective in the treatment of congenital vaginal agenesis, as it is a simple and safe procedure with promising outcomes.

Abstract
The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome (OMIM 277000) is characterized by agenesis of the uterus and upper part of the vagina in females with normal ovarian function. While genetic causes have been identified for a small subset of patients and epigenetic mechanisms presumably contribute to the pathogenic unfolding, too, the etiology of the syndrome has remained largely enigmatic. A comprehensive understanding of gene activity in the context of the disease is crucial to identify etiological components and their potential interplay. So far, this understanding is lacking, primarily due to the scarcity of samples and suitable tissue. In order to close this gap, we profiled endometrial tissue of uterus rudiments in a large cohort of MRKH patients using RNA-seq and thereby provide a genome-wide view on the altered transcription landscape of the MRKH syndrome. Differential and co-expression analyses of the data identified cellular processes and candidate genes that converge on a core network of interconnected regulators that emerge as pivotal for the perturbed expression space. With these results and browsable access to the rich data through an online tool we seek to accelerate research to unravel the underlying biology of the syndrome.

Abstract
BACKGROUND Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also referred to as Müllerian aplasia, is a congenital disorder characterized by aplasia of the uterus and upper part of the vagina in females with normal secondary sex characteristics and a normal female karyotype (46,XX). MAIN BODY The diagnosis is often made during adolescence following investigations for primary amenorrhea and has an estimated prevalence of 1 in 5000 live female births. MRKH syndrome is classified as type I (isolated uterovaginal aplasia) or type II (associated with extragenital manifestations). Extragenital anomalies typically include renal, skeletal, ear, or cardiac malformations. The etiology of MRKH syndrome still remains elusive, however increasing reports of familial clustering point towards genetic causes and the use of various genomic techniques has allowed the identification of promising recurrent genetic abnormalities in some patients. The psychosexual impact of having MRKH syndrome should not be underestimated and the clinical care foremost involves thorough counselling and support in careful dialogue with the patient. Vaginal agenesis therapy is available for mature patients following therapeutical counselling and education with non-invasive vaginal dilations recommended as first-line therapy or by surgery. MRKH syndrome involves absolute uterine factor infertility and until recently, the only option for the patients to achieve biological motherhood was through gestational surrogacy, which is prohibited in most countries. However, the successful clinical trial of uterus transplantation (UTx) by a Swedish team followed by the first live-birth in September, 2014 in Gothenburg, proofed the first available fertility treatment in MRKH syndrome and UTx is now being performed in other countries around the world allowing women with MRKH syndrome to carry their own child and achieve biological motherhood. CONCLUSION Several advances in research across multiple disciplines have been made in the recent years and this kaleidoscopic review provides a current status of various key aspects in MRKH syndrome and provides perspectives for future research and improved clinical care.

Abstract
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.

Abstract
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.

Abstract
Objective To present the case of a squamous carcinoma in the neovagina of a patient with Mayer-Rokitansky-Küster-Hauser syndrome and review of the literature related to treatment and prognosis of vaginal neoplasms or HPV infection in transgender women or with MRKH syndrome. Materials and methods A 56-year-old woman consulted to the Hospital Universitario of Sevilla (Spain). During the clinical examination, a exophytic tumor at the bottom of the vagina was found and the biopsy reported squamous carcinoma and positive nucleic acid amplification test for human papilloma (HPV) type 16. A literature search of case reports, case series and observational studies published from 2000 to October 2019 in English and Spanish was performed in Medline via PubMed, with the follow- ing terms: "congenital abnormalities"; "Mullerian aplasia"; "neovagina"; "Vaginal neoplasms"; "Squamous carcinoma"; "HPV infection" was performed. Results 14 studies were finally included; seven corresponded to squamous cell carcinoma, three to adenocarcinoma and four reported HPV infection only. All of the squamous cell carcinomas were at advanced stages due to local or lymphatic compro- mise and received radiotherapy with concomitant chemotherapy or radical surgery. The prognosis was bad in three of the cases. Patients with adenocarcinoma also presented with advanced lesions due to local extensión and received surgical treatment and two cases received concomitant chemotherapy. Only one patient was followed-up for five years or more. HPV infection is common in women who underwent neovagina reconstruction. Conclusions Patients with neovagina are susceptible to develope squamous carcinomas or adenocarcinomas depending if skin or intestinal tissue grafts are used. According to local compromise at the time of diagnosis, radical or combined treatments are required. Which screening strategies for HPV, squamous cell carcinomas and adenocarcinoma is to be investigated.

Abstract
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.

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. J Pediatr Adolesc Gynecol 2019; 32:284-287. [PMID: 30114439 DOI: 10.1016/j.jpag.2018.07.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2018] [Revised: 07/12/2018] [Accepted: 07/20/2018] [Indexed: 02/02/2023]
Abstract
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.

Abstract
Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome is a female reproductive system disorder. It is characterized by a defect in the Müllerian ducts development, and it causes the absence of the uterus in variable degrees in upper vaginal hypoplasia. In addition, it is often associated with the unilateral renal dysplasia. Müllerian agenesis affects 1 in 4500 newborn girls and is considered as a sporadic anomaly. Women with MRKH Syndrome have a normal female chromosome pattern 46, XX with normal ovarian function. The presence of bilateral kidney agenesis with a pelvic pancake-shaped kidney is a rare condition, and a few cases have been reported in medical journals. This case study focuses on a case of MRKH Syndrome with bilateral renal agenesis and a pancake-shaped kidney.

Abstract
Coexistence of Mayer-Rokitansky-Küster-Hauser syndrome and gonadal dysgenesis is extremely rare, and a case of Mayer-Rokitansky-Küster-Hauser syndrome with a uterine cervix and normal vagina has not been reported. Here, we report such a case associated with gonadal dysgenesis. A 17-year-old female presented with primary amenorrhea and undeveloped secondary sexual characteristics. Genital examination revealed a uterine cervix and normal vagina without a uterine body and ovaries. An endocrine study showed hypergonadotrophic hypogonadism. The karyotype was 46,XX. Laparoscopy revealed a rudimentary uterus, normal fallopian tubes and bilateral streak ovaries. There were no other associated malformations. Hormonal substitution therapy was started for development of secondary sexual characteristics and prevention of osteoporosis, but the problem of infertility is unresolved.

Abstract
The Mayer-Rokitansky-Küster-Hauser syndrome is the congenital absence or underdevelopment of the uterus and vagina even though the external genitalia, ovaries and ovarian function are normal. This condition is uncommon in Cameroon. A 23-year-old woman of the Fulbé tribe, a predominantly Islamic tribe of the northern part of Cameroon, complained of the absence of menstruation after age of puberty and lower abdominal pain occurring almost at the same period every month. She has been married polygamously for 10 years and has been having normal, satisfactory sexual intercourse. The sonographic and laparoscopic findings of this patient were consistent with Mayer-Rokitansky-Küster-Hauser syndrome. The patient was counseled for in vitro fertilization and surrogacy. Patients with Mayer-Rokitansky-Küster-Hauser syndrome typically present with primary amenorrhea during adolescence. With the existing medical technology in Cameroon, this condition is easily accessible in tertiary healthcare facilities. Patients with Mayer-Rokitansky-Küster-Hauser syndrome could become mothers through in vitro fertilization and surrogacy, but the cost is prohibitive in Cameroon.

Abstract
Hypothesis/Aims of Study Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is the second most common cause of primary amenorrhea. The ESHRE/ESGE categorizes this disorder within the class 5 uterine malformation of the female genital tract anomalies. It is characterized by congenital absence of the uterus, cervix, and upper part of the vagina in otherwise phenotypically normal 46XX females. These patients have normal ovaries, biphasic ovarian cycle, and female psychosexual identification. Laparoscopic Vecchietti's operation-surgical method in which the vagina increases in size by gradually applying traction to the vaginal vault-is one of the methods used to treat MRKH. The aim of this study was to establish the urogynecological and sexual functions after Vecchietti's operation. Study Design Materials and Methods Fifteen patients with MRKHS who underwent laparoscopic Vecchietti's operation were included. A control group of 15 age-matched, childless, sexually active women were examined during the same period. All patients underwent the basic evaluation of anatomical outcomes. Sexual outcomes were established by the Polish validated Female Sexual Function Index (FSFI) questionnaire. Continence status was assessed by Polish validated Urinary Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7). Results Mean age of MRKH group was 22.06±5.13 yrs. Mean follow-up after surgery was 8.02±3.43 yrs. Mean age of women from control group was 22.4±4.35. Mean FSFI scores show good quality of sexual life in both groups. UDI-6 scores showed that patients after Vecchietti surgery have urogynecological problems significantly more often than healthy women do. Based on the IIQ-7, it is evident that one patient from the MRKH group (6,6%) suffers from stress urinary incontinence and the rest (20%) have rather irritative problems with the functioning of the lower urinary tract. Conclusion Quality of sexual life after the Vecchietti's operation in long-term follow-up does not differ from that of healthy women, but these patients suffer more frequent from urogynecological complaints. The trial is registered with NCT03809819.

Abstract
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.

Abstract
PURPOSE OF REVIEW Abnormal development of the uterus, cervix, and proximal 2/3 of the vagina results in Müllerian duct anomalies. Because of the close embryologic relationship between the developing female genital and urinary tracts, abnormalities of the urinary tract often accompany Müllerian duct anomalies. Magnetic resonance imaging (MRI) is the current gold standard-imaging modality in the evaluation of the anomalies of the female reproductive tract. This article discusses the imaging evaluation of Müllerian duct and accompanying urinary tract anomalies with a particular focus on the MRI findings. RECENT FINDINGS Several studies have shown high concordance between MRI and three-dimensional ultrasound (3D US) in the evaluation of Müllerian duct abnormalities. 3D US is more cost effective than MRI but has not yet been fully substantiated as a comparable modality to MRI. Additionally, 3D US does not help elucidate concomitant anomalies of the urologic system. Müllerian duct anomalies are often associated with abnormalities of the urinary tract. Evaluation with MRI is important for the diagnosis of Müllerian duct anomalies and also helps with potential surgical planning.

Abstract
PURPOSE Several classification systems for female genital tract anomalies exist but are of limited use in clinical practice. We, therefore, assessed the applicability and ease of use of the new ESHRE/ESGE classification, using only patient records. METHODS This retrospective, single-center, proof-of-principle study systematically analyzed the surgical reports and other hospital records of 920 inpatients and outpatients treated for confirmed female genital tract congenital malformations at a major German university hospital during 2003-2013. Using only this information, a non-expert (medical student) assigned patients to an ESHRE/ESGE class, rating ease of classification based on the time and the number of additional medical records required. Results were verified by an expert gynecologist, who also classified any malformations previously left unclassified. Data analysis used descriptive statistics. RESULTS The non-expert successfully classified 859/920 patients (93.4%), rating classification as "easy" for 836/859 (90.9%) and "moderately difficult" for 23/859 (2.5%) patients. The expert gynecologist successfully classified 60 (60/920, 6.5%) of the remaining 61 patients rated as "difficult" by the non-expert, but was unable to accurately subclassify 1 patient (1/920, 0.1%) because the operative report lacked the relevant details. 251/920 (27.3%) patients had associated non-Müllerian anomalies, most frequently renal (20.9%) and skeletal (9.1%) malformations. CONCLUSIONS The ESHRE/ESGE classification provides a generally applicable, comprehensive, and adequately specific classification of female genital tract congenital malformations. It offers an efficient basis for communication between non-experts and experts in the field and is, therefore, useful in clinical management and treatment planning.

Abstract
BACKGROUND Hydrocolpos and hydrometrocolpos are rare malformations caused by accumulation of secretion due to congenital obstruction of the vagina. Hydro(metro)colpos may be isolated or can be combined with other malformations as part of a syndromic disorder. We report on a series of 20 cases with hydro(metro)colpos diagnosed prenatally, delineate the differential diagnoses, and illustrate the spectrum of associated malformations. SUBJECTS AND METHODS This was a retrospective study involving 20 fetuses with hydro(metro)colpos at two large tertiary referral centers in Germany over an 18-year period (2000-2017). RESULTS The median diagnosis was made at 30+4 weeks of gestation, the earliest at 20+6 weeks, the latest at 37+2 weeks. All 20 fetuses presented with the typical cystic structure behind the fetal bladder. Additional malformations included urogenital malformations, hexadactyly, and heart defects. Postnatal follow-up revealed that hydro(metro)colpos was associated with anorectal malformation in 11/20 fetuses, McKusick-Kaufman syndrome or Bardet-Biedl syndrome in 4/20 fe tuses, Mayer-Rokitansky-Küster-Hauser syndrome in 3/20 fetuses, and Herlyn-Werner-Wunderlich syndrome in 1/20. In 1 fetus pressure from an intraabdominal teratoma resulted in prenatal hydro(metro)colpos. CONCLUSION Hydro(me tro)colpos is a rare prenatal sonographic feature. Multidisciplinary prenatal counseling should include all potential syndromes that can present with hydro(metro)colpos in the prenatal setting.

Abstract
BACKGROUND Little is known about the genetic contribution to Müllerian aplasia, better known to patients as Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Mutations in two genes (WNT4 and HNF1B) account for a small number of patients, but heterozygous copy number variants (CNVs) have been described. However, the significance of these CNVs in the pathogenesis of MRKH is unknown, but suggests possible autosomal dominant inheritance. We are not aware of CNV studies in consanguineous patients, which could pinpoint genes important in autosomal recessive MRKH. We therefore utilized SNP/CGH microarrays to identify CNVs and define regions of homozygosity (ROH) in Anatolian Turkish MRKH patients. RESULTS Five different CNVs were detected in 4/19 patients (21%), one of which is a previously reported 16p11.2 deletion containing 32 genes, while four involved smaller regions each containing only one gene. Fourteen of 19 (74%) of patients had parents that were third degree relatives or closer. There were 42 regions of homozygosity shared by at least two MRKH patients which was spread throughout most chromosomes. Of interest, eight candidate genes suggested by human or animal studies (RBM8A, CMTM7, CCR4, TRIM71, CNOT10, TP63, EMX2, and CFTR) reside within these ROH. CONCLUSIONS CNVs were found in about 20% of Turkish MRKH patients, and as in other studies, proof of causation is lacking. The 16p11.2 deletion seen in mixed populations is also identified in Turkish MRKH patients. Turkish MRKH patients have a higher likelihood of being consanguineous than the general Anatolian Turkish population. Although identified single gene mutations and heterozygous CNVs suggest autosomal dominant inheritance for MRKH in much of the western world, regions of homozygosity, which could contain shared mutant alleles, make it more likely that autosomal recessively inherited causes will be manifested in Turkish women with MRKH.

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.

Genetic analysis of Mayer-Rokitansky-Kuster-Hauser syndrome in a large cohort of families. Fertil Steril 2017; 108:145-151.e2. [PMID: 28600106 PMCID: PMC5770980 DOI: 10.1016/j.fertnstert.2017.05.017] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2017] [Revised: 05/10/2017] [Accepted: 05/11/2017] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To study the genetic cause of Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH). Although a few candidate genes and genomic domains for have been reported for MRKH, the genetic underpinnings remain largely unknown. Some of the top candidate genes are WNT4, HNF1B, and LHX1. The goals of this study were to: 1) determine the prevalence of WNT4, HNF1B, and LHX1 point mutations, as well as new copy number variants (CNVs) in people with MRKH; and 2) identify and characterize MRKH cohorts. DESIGN Laboratory- and community-based study. SETTING Academic medical centers. PATIENT(S) A total of 147 MRKH probands and available family members. INTERVENTIONS(S) DNA sequencing of WNT4, HNF1B, and LHX1 in 100 MRKH patients, chromosomal microarray analysis in 31 North American MRKH patients, and characterization and sample collection of 147 North American and Turkish MRKH probands and their families. MAIN OUTCOME MEASURE(S) DNA sequence variants and CNVs; pedigree structural analysis. RESULT(S) We report finding CNVs in 6/31 people (∼19%) with MRKH, but no point mutations or small indels in WNT4, HNF1B, or LHX1 in 100 MRKH patients. Our MRKH families included 43 quads, 26 trios, and 30 duos. Of our MRKH probands, 87/147 (59%) had MRKH type 1 and 60/147 (41%) had type 2 with additional anomalies. CONCLUSION(S) Although the prevalence of WNT4, HNF1B, and LHX1 point mutations is low in people with MRKH, the prevalence of CNVs was ∼19%. Further analysis of our large familial cohort of patients will facilitate gene discovery to better understand the complex etiology of MRKH.

Abstract
Mayer-Rokitansky-Küster-Hauser syndrome is a rare disorder consisting of vaginal aplasia and other müllerian duct abnormalities. Urinary tract malfor-mations possibly leading to renal failure are also common. For these patients, kidney transplant remains the best option. However, aberrant anatomy and scarring from previous operations may actually preclude successful implantation of the graft. In this setting, careful pretransplant evaluation with high-resolution imaging studies and multidisciplinary planning are mandatory. We report on a patient with type B Mayer-Rokitansky-Küster-Hauser syndrome, left renal agenesis, right pelvic kidney, grade 3 cystocele, reconstructed vagina, and abnormal vasculature of the pelvis who developed end-stage renal disease due to chronic pyelonephritis. After a thorough preoperative assessment, she eventually underwent simultaneous right pelvic nephrectomy and living-donor kidney transplant. Despite the complexity of the procedure, there were no intraoperative or postoperative complications. After 1 year of follow-up, she is doing well with excellent graft function.

Abstract
Müllerian anomalies include a spectrum of anatomic variants of the genital tract arising from abnormal embryologic development, ranging from incomplete resorption of uterine septa to complete vaginal agenesis. Nonobstructive anomalies are often recognized later than obstructive anomalies, because women do not present with pain. However, nonobstructive anomalies frequently have a negative impact on sexual and reproductive health, and careful evaluation and management of these disorders is warranted. This review focuses on the surgical management of nonobstructive Müllerian anomalies.
