ABSTRACT

BACKGROUND: Mayer-Rokitansky-Kuster-Hauser (MRKH) Syndrome, the second important cause of primary amenorrhea, is characterized by complete mullerian agenesis in the presence of normal karyotype and normal functioning ovaries. Incidence is one in 4500 females. Treatment options include surgical and non-surgical methods. Surgical treatment by creating a neovagina between bladder and rectum is preferred as it gives immediate results. AIM: To evaluate the anatomical and functional outcomes of modified vaginoplasty procedures conducted in our institution. METHODS: An ambispective cohort study was conducted in the Department of Obstetrics and Gynaecology, at a tertiary care hospital and included 10 cases of MRKH syndrome, who underwent surgical treatment in our department. Postoperative outcome was noted. Sexual function was evaluated using the Female Sexual Function Index (FSFI) score. RESULTS: The mean duration of surgery was 40 minutes. The average blood loss during surgery in patients undergoing vaginoplasty was 60 ml. The mean length of the neovagina as measured 1 month after surgery was 7.9 cms. FSFI score was >30 in eight patients. Two patients were lost to follow-up. CONCLUSION: Modified McIndoe vaginoplasty is a simple, safe, and cost-effective procedure in the hands of experts. Only mature patients willing to follow the instructions and planning to get married soon should undergo this surgery.

ABSTRACT

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rare congenital disorder that affects the female reproductive system and is characterized by an underdeveloped or absent uterus and vagina. A 17-year-old unmarried female was admitted into the Department of Endocrinology, Mymensingh Medical College Hospital, Bangladesh in November 2023 for evaluation of primary amenorrhea and poorly controlled diabetes mellitus. She was the 5th issue of non-consanguineous marriage delivered at term by normal vaginal delivery. Her growth pattern and developmental milestones were normal. She had no history of galactorrhea, chronic or cyclic pelvic pain, thyroid dysfunction, excessive exercise, psychiatric illness, or drug abuse. There was no history of such type of illness in her family. She was diagnosed with diabetes mellitus two years back without classic symptoms, and at that time, her blood glucose was 22 mmol/L. She was prescribed metformin and gliclazide. She had no history of hypoglycemia, hyperglycemic crises, or hospital admission. On examination, her body build and nutritional status were normal. Anemia, jaundice, edema, dehydration, lymphadenopathy, acne, hirsutism, acanthosis nigricans, abdominal striae and vitiligo were absent. Her blood pressure was 110/70 without the postural drop, thyroid gland was not enlarged, anthropometric measurements were normal and BMI was 18.4 kg/m2. Her tanner stage was P5 & B4. Genital examination revealed normal female external genitalia, and a blind vaginal pouch was found. Other systemic examinations revealed no abnormality. On laboratory reports, her blood glucose was uncontrolled (HbA1c-10.2%) with glycosuria. Thyroid function test and gonadal hormones were normal. Ultrasonogram of the abdomen revealed uterus, cervix, and upper part of the vagina are absent, and an ectopic left kidney.

ABSTRACT

BACKGROUND Laparoscopic-perineal neovagina construction by sigmoid colpoplasty is a popular therapeutic approach for patients with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. The conventional approach requires an auxiliary abdominal incision to exteriorize the descending colon to fix the anvil for end-to-end colorectal anastomosis. We modified the natural orifice specimen extraction surgery (NOSES) approach by exteriorizing the descending colon through the artificial neovaginal tunnel to replace the anvil extracorporeally, without requiring an auxiliary abdominal incision. It was a more minimally invasive technique. CASE REPORT We performed this modified laparoscopic-perineal sigmoid colpoplasty in a 26-year-old woman with MRKH syndrome. We cut off a segment of the sigmoid colon with a vascular pedicle to make a new vagina out of it, the same as in the traditional laparoscopic-perineal sigmoid colpoplasty. What is new about this technique is that it has no need for abdominal incision and is more minimally invasive. The operating time was 315 min. No postoperative complications occurred. The postoperative hospital stay was 4 days. The modified laparoscopic-perineal approach, free from an auxiliary abdominal incision, demonstrated advantages, including a shorter hospital stay, expedited recovery, and comparable anatomical outcomes, when compared with the traditional approach. This innovation improves the surgical experience for patients with MRKH syndrome, addressing the physical and psychological aspects of their condition. CONCLUSIONS This refined laparoscopic-perineal neovagina construction by sigmoid colpoplasty represents a feasible and minimally invasive technique. It is an attractive option for MRKH syndrome patients in need of vaginal reconstruction, offering a streamlined procedure with reduced postoperative recovery time and enhanced patient outcomes.

ABSTRACT

Objective: To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies. Methods: A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed. Results: A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common. Conclusions: Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

ABSTRACT

Objective: To explore the age of onset and consultation, the main clinical manifestations, common types of combined malformations, the relationship of endometriosis, surgical prognosis and different types of proportion of adolescent female reproductive system dysplasia. Methods: The medical records of 356 patients (aged 10-19) with female reproductive system dysplasia in Women's Hospital, School of Medicine, Zhejiang University from January 2003 to August 2018 were collected and retrospectively analyzed. Results: (1) Among the 356 adolescent dysplasia patients, uterine dysplasia (23.6%, 84/356), oblique vaginal septum syndrome (OVSS; 22.5%, 80/356) and vaginal dysplasia (21.6%, 77/356) were the most frequent ones, followed by multi-sectional dysplasia (16.0%, 57/356), other types of developmental abnormalities like external genitaliaand urogenital fistula (13.5%, 48/356) and Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome; 2.8%, 10/356). (2) There were significant differences between the median age of onset and the age of consultation of patients with OVSS and other types of abnormalities except hymen atresia (both P<0.05). In contrast, there were no significant differences between the age of onset and the age of consultation of the patients of uterine dysplasia, vaginal dysplasia, hymen atresia, MRKH syndrome and multi-sectional dysplasia (all P>0.05). (3) The clinical manifestations were lack of specificity, and mainly abnormal finding was lower abdominal pain. (4) After admission, the majority of patients underwent comprehensive cardiopulmonary examination (71.3%, 254/356) and urinary system examination (63.5%, 226/356). Only 18.3% (65/356) of patients had completed abdominal organ examination, and 5.9% (21/356) skeletal system examination. About other systemic malformations, urological malformations were the most common (27.5%, 98/356), followed by anorectal malformation (0.6%, 2/356), heart malformations (0.3%, 1/356), and spinal malformations (0.3%, 1/356). 46.4% (84/181) of the surgical patients were diagnosed with combined endometriosis. Patients with obstructive genital tract malformations were more likely to combine with endometriosis than non-obstructive ones [50.3% (74/147) vs 29.4% (10/34); P<0.05]. However, there was no significant difference between the severity of endometriosis of those two kinds (P>0.05). (5) Totally 308 patients were followed up successfully with a median of 25.0 years old, and 20 cases were treated again; 12.0% (37/308) of them were suffering from menstrual disorder and 33.1% (102/308) of them with dysmenorrhea. Totally 130 patients had sexually active reported no sexual problems. Conclusions: Uterine dysplasia, OVSS and vaginal dysplasia are the most common syndromes in adolescent female reproductive system dysplasia along with frequent cases of coexisting urinary malformations and increasing risks of endometriosis. Meanwhile, the lack of specificity of clinical manifestations might delay the timely diagnosis and treatment after the onset of symptoms. Nonetheless, most patients could achieve good surgical outcomes.

ABSTRACT

INTRODUCTION: Rokitansky syndrome or Mayer Rokitansky Kuster Hauser (SRKMH) is a rare congenital malformation defined by uterovaginal aplasia. The aim of the treatment is to create a neovagina and restore sexual life. However, postoperative results in terms of sexual and overall quality of life of patients remain controversial. AIM: To evaluate the quality of life and sexuality of patients operated on for Rokitansky syndrome. METHODS: This was a retrospective and comparative study between two groups of patients. The first group consisted of patients who had undergone vaginoplasty as part of SRKMH. The second group was that of the controls. Control in terms of sexual function by the Ar FSFI (Arab FemaleSexualFunction Index) and quality of life by the SF36 (Short Forms Health Survey) were used in both groups. RESULTS: The average age of patients operated on for SRKMH was 22.53 years. Eighteen of these patients (60%) were sexually active at the time of the study. Patients operated on for SRKMH had a significantly lower Ar FSFI score compared to the control group. The two areas most affected were lubrication and pain. Likewise, patients who underwent vaginoplasty had a significantly lower SF 36 score compared to the control group. The psychological component was the most affected of the different components of quality of life. CONCLUSION: Sexual function and quality of life after vaginoplasty in the context of Rokitansky syndrome remains unsatisfactory despite the anatomical result.

ABSTRACT

Obstructed Hemi Vagina with Ipsilateral Renal Agenesis (OHVIRA) syndrome is a rarely encountered müllerian duct anomaly. Delayed diagnosis is common due to normal onset of puberty and menstruation. We report a case of a woman in her early 20s with a background history of multiple emergency department visits, ward admissions and surgeries for chronic abdominal pain. She was reviewed at 1 month postlaparotomy for recurrent pelvic abscess and was finally diagnosed to have an OHVIRA syndrome, 11 years after her first clinical presentation. Excision of the vaginal septum completely resolved her symptoms. We are reporting this case to highlight the clinical implications resulting from the delayed diagnosis, to look into factors contributing to the delay and to highlight the importance of having a high index of suspicion to diagnose this unique condition.

ABSTRACT

BACKGROUND: The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare condition with significant psychological implications. However, our understanding of its impact on postoperative sexual function and mental health is still limited. AIM: Evaluate the mental health status and sexual functioning of women with MRKH syndrome after vaginoplasty surgery. METHODS: We enrolled 53 cases with MRKH syndrome who underwent artificial vaginoplasty. The participants were asked to participate in a two-round survey conducted between February 2021 during the covid-19 period and March 2023. The survey included questionnaires to measure depression, anxiety, self-esteem, and sexual functioning. Differences between scores over time were analysed using a paired sample t-test, and we assessed the correlation between mental health and sexual functioning. RESULTS: In the first round, patients' mean ± SD age at surgery was 23.6 ± 4.5 years old, and the mean ± SD time that had elapsed since surgery at the time of the survey was 34.2 ± 20.8 months. None of the patients reported low self-esteem, 45.3 % reported mild-to-moderate depression, and 34.0 % reported mild anxiety. Thirty patients have had vaginal intercourse during the last six months. The mean ± SD Female Sexual Functioning Index score was 24.6 ± 4.4, and 60.0 % had a score of 23.5 or higher, indicating high sexual functioning. The sexual functioning scores were positively correlated with self-esteem scores and negatively correlated with depression or anxiety scores (p < 0.05). There was no significant improvement in patient's mental health status and sexual function between the second round survey (71.3 ± 17.8 months after surgery) and the first round survey (p > 0.05). In contrast, the sexual arousal of FSFI were significantly higher in the second survey round (p < 0.05). CONCLUSION: Most patients undergoing vaginoplasty reported persisting mental health challenges. However, the majority reported good sexual functioning.

ABSTRACT

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital anomaly characterized by agenesis/aplasia of the uterus and upper part of the vagina in females with normal external genitalia and a normal female karyotype (46,XX). Patients typically present during adolescence with complaints of primary amenorrhea where the diagnosis is established with significant implications including absolute infertility. Most often cases appear isolated with no family history of MRKH syndrome or related anomalies. However, cumulative reports of familial recurrence suggest genetic factors to be involved. Early candidate gene studies had limited success in their search for genetic causes of MRKH syndrome. More recently, genomic investigations using chromosomal microarray and genome-wide sequencing have been successful in detecting promising genetic variants associated with MRKH syndrome, including 17q12 (LHX1, HNF1B) and 16p11.2 (TBX6) deletions and sequence variations in GREB1L and PAX8, pointing towards a heterogeneous etiology with various genes involved. With uterus transplantation as an emerging fertility treatment in MRKH syndrome and increasing evidence for genetic etiologies, the need for genetic counseling concerning the recurrence risk in offspring will likely increase. This review presents the advancements in MRKH syndrome genetics from early familial occurrences and candidate gene searches to current genomic studies. Moreover, the review provides suggestions for future genetic investigations and discusses potential implications for clinical practice.

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

BACKGROUND: There is wide variation in the language used to describe Mullerian structures. To standardize terminology, the American Society of Reproductive Medicine (ASRM) created the Mullerian Anomalies Classification (MAC) in 2021. The objective of this study was to evaluate the applicability of the MAC nomenclature to pediatric patients with cloaca. METHODS: A retrospective review of all patients with cloaca was performed at a single institution. Descriptions of Mullerian structures were evaluated and compared to the ASRM MAC categories. Descriptive statistics were used to report findings. RESULTS: 36 patients with cloaca were identified, 13 (36%) of whom had congenital Mullerian structures that could not be adequately described by the MAC terminology. All 13 patients had two hemiuteri that were not connected in the midline and were not accurately described as uterus didelphys. Additionally, 5 of these 13 patients had reproductive anatomy that was connected by a fistula or ectopic connection to other pelvic structures. CONCLUSION: Despite the ASRM expansion of the Mullerian anomalies nomenclature, more than a third of our patients with cloaca could not have their Mullerian structures accurately described. Describing anatomy with accurate and consistent language can improve communication between healthcare providers and may allow patients and families to better anticipate fertility options. STUDY TYPE: Retrospective. LEVEL OF EVIDENCE: IV.

ABSTRACT

Mayer-Rokitansky-Kuster-Hauser syndrome also known as mullerian agenesis is a rare congenital condition in which there is absence of uterus along with upper vagina. Patient usually presents with primary amenorrhea with or without cyclical lower abdominal pain but have normal secondary sexual characters. Modified McIndoe Vaginoplasty with amnion graft is the commonest surgery performed worldwide. A 23 year old girl with normal secondary sexual characters presented with primary amenorrhea with cyclical lower abdominal pain; on examination blind vagina was present. Vaginoplasty with amnion graft was done and vaginal mould was placed. Vaginal dilatation with Hegar's dilator was done weekly until 6 weeks. She is under regular follow-up at present and advised for regular manual dilation at home. McIndoe Vaginoplasty with amnion graft is a simple yet rewarding procedure especially in low resource countries like ours, with good success rate and with minimal postoperative complications. Keywords: Amnion graft; Mayer-Rokitansky-Kuster-Hauser Syndrome; Modified McIndoe Vaginoplasty; Primary amenorrhea; Secondary sexual characters.

ABSTRACT

Mesonephric adenocarcinomas (MAs) and mesonephric-like adenocarcinomas (MLAs) are rare, aggressive neoplasms that arise in the gynecologic tract and show overlapping morphologic, immunohistochemical, and molecular features. While MAs occur in the cervix and are thought to arise from mesonephric remnants, MLAs occur in the endometrium and ovary and are believed to originate from transdifferentiation of Müllerian lesions. Both MAs and MLAs show a variety of architectural patterns, exhibit frequent expression of GATA3 by immunohistochemistry, and harbor KRAS mutations. In a recent article published in The Journal of Pathology, Kommoss and colleagues used DNA methylation profiling to extend these similarities and showed that MLAs and MAs cluster together based on their epigenetic signatures and are epigenetically distinct from other Müllerian adenocarcinomas. They also showed that MLAs and MAs harbor a high number of global copy number alterations. This study provides evidence that MLAs more closely resemble MAs than Müllerian carcinomas on an epigenetic level. As a result, the authors argue that MLA should be renamed 'mesonephric-type adenocarcinoma.' Further research is needed to establish the relationship between these two entities, their etiology, and pathogenesis. © 2024 The Pathological Society of Great Britain and Ireland.

ABSTRACT

The upper Müllerian duct (MD) is patterned and specified into two morphologically and functionally distinct organs, the oviduct and uterus. It is known that this regionalization process is instructed by inductive signals from the adjacent mesenchyme. However, the interaction landscape between epithelium and mesenchyme during upper MD development remains largely unknown. Here, we performed single-cell transcriptomic profiling of mouse neonatal oviducts and uteri at the initiation of MD epithelial differentiation (postnatal day 3). We identified major cell types including epithelium, mesenchyme, pericytes, mesothelium, endothelium, and immune cells in both organs with established markers. Moreover, we uncovered region-specific epithelial and mesenchymal subpopulations and then deduced region-specific ligand-receptor pairs mediating mesenchymal-epithelial interactions along the craniocaudal axis. Unexpectedly, we discovered a mesenchymal subpopulation marked by neurofilaments with specific localizations at the mesometrial pole of both the neonatal oviduct and uterus. Lastly, we analyzed and revealed organ-specific signature genes of pericytes and mesothelial cells. Taken together, our study enriches our knowledge of upper MD development, and provides a manageable list of potential genes, pathways, and region-specific cell subtypes for future functional studies.

ABSTRACT

Robert's uterus is a rare Müllerian duct anomaly (MDA) characterized by complete asymmetric septum dividing uterine cavity into two non-communicating parts. This study offers insights into diagnosing and management of this condition in a young patient, and a systematic literature review. The review included 19 studies from 2013 to 2023. 11.4% of women reported a history of miscarriage and 5.7% primary infertility. Dysmenorrhea was the most frequent symptom (54.3%), and 14.3% of patients had a coexisting endometriosis. The surgical interventions most commonly combine laparoscopic and hysteroscopic techniques. Robert's uterus requires heightened clinical awareness for early diagnosis, particularly in young women.

ABSTRACT

In avian embryos, xenoestrogens induce abnormalities in reproductive organs, particularly the testes and Müllerian ducts (MDs). However, the molecular mechanisms remain poorly understood. We investigated the effects of ethynylestradiol (EE2) exposure on gene expression associated with reproductive organ development in Japanese quail embryos. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) analysis revealed that the left testis containing ovary-like tissues following EE2 exposure highly expressed the genes for steroidogenic enzymes (P450scc, P45017α, lyase, and 3ß-HSD) and estrogen receptor-ß, compared to the right testis. No asymmetry was found in these gene expression without EE2. EE2 induced hypertrophy in female MDs and suppressed atrophy in male MDs on both sides. RNA sequencing analysis of female MDs showed 1,366 differentially expressed genes between developing left MD and atrophied right MD in the absence of EE2, and these genes were enriched in Gene Ontology terms related to organogenesis, including cell proliferation, migration and differentiation, and angiogenesis. However, EE2 reduced asymmetrically expressed genes to 21. RT-qPCR analysis indicated that genes promoting cell cycle progression and oncogenesis were more highly expressed in the left MD than in the right MD, but EE2 eliminated such asymmetric gene expression by increasing levels on the right side. EE2-exposed males showed overexpression of these genes in both MDs. This study reveals part of the molecular basis of xenoestrogen-induced abnormalities in avian reproductive organs, where EE2 may partly feminize gene expression in the left testis, developing as the ovotestis, and induce bilateral MD malformation by canceling asymmetric gene expression underlying MD development.

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.
