RESUMO

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.

RESUMO

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.

RESUMO

Estradiol is an important regulator of bone accumulation and maintenance. Circulating estrogens are primarily produced by the gonads. Aromatase, the enzyme responsible for the conversion of androgens to estrogen, is expressed by bone marrow cells (BMCs) of both hematopoietic and nonhematopoietic origin. While the significance of gonad-derived estradiol to bone health has been investigated, there is limited understanding regarding the relative contribution of BMC derived estrogens to bone metabolism. To elucidate the role of BMC derived estrogens in male bone, irradiated wild-type C57BL/6J mice received bone marrow cells transplanted from either WT (WT(WT)) or aromatase-deficient (WT(ArKO)) mice. MicroCT was acquired on lumbar vertebra to assess bone quantity and quality. WT(ArKO) animals had greater trabecular bone volume (BV/TV p = 0.002), with a higher trabecular number (p = 0.008), connectivity density (p = 0.017), and bone mineral content (p = 0.004). In cortical bone, WT(ArKO) animals exhibited smaller cortical pores and lower cortical porosity (p = 0.02). Static histomorphometry revealed fewer osteoclasts per bone surface (Oc.S/BS%), osteoclasts on the erosion surface (ES(Oc+)/BS, p = 0.04) and low number of osteoclasts per bone perimeter (N.Oc/B.Pm, p = 0.01) in WT(ArKO). Osteoblast-associated parameters in WT(ArKO) were lower but not statistically different from WT(WT). Dynamic histomorphometry suggested similar bone formation indices' patterns with lower mean values in mineral apposition rate, label separation, and BFR/BS in WT(ArKO) animals. Ex vivo bone cell differentiation assays demonstrated relative decreased osteoblast differentiation and ability to form mineralized nodules. This study demonstrates a role of local 17ß-estradiol production by BMCs for regulating the quantity and quality of bone in male mice. Underlying in vivo cellular and molecular mechanisms require further study.

RESUMO

ABSTRACT: Mayer-Rokitansky-Küster-Hauser syndrome is a congenital disorder typified by an underdeveloped female reproductive tract. An exploratory online survey of adults with Mayer-Rokitansky-Küster-Hauser syndrome found that many did not recall receiving the human papillomavirus vaccine, and answers to knowledge questions suggested inadequate human papillomavirus counseling. However, recalled vaccine counseling was associated with improved uptake.

RESUMO

BACKGROUND: Rubinstein-Taybi syndrome (RSTS) is a multi-system neurodevelopmental condition caused by deficiency of CREBBP (16p13.3) or EP300 (22q13.2). Müllerian agenesis, or Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, is defined as congenital agenesis of the uterus, cervix, and upper vagina without a definite genetic cause. INDEX CASE AND CASE SERIES: We present a 14-year-old female with RSTS type 1 (CREBBP, c.4395-2A>C) and MRKH, the first documented in the literature. Following presentation to Gynecology for anticipatory guidance regarding future menstrual suppression and follow-up of previously diagnosed labial adhesions, exam under anesthesia revealed a single urogenital opening with cystoscopy demonstrating a normal urethra and bladder. Laboratory evaluation was consistent with peripubertal female gonadotropins and estradiol, 46,XX karyotype, and normal microarray, and a pelvic MRI confirmed Müllerian agenesis. Given this case, we assessed our cohort of females with RSTS and found that 4 of 12 individuals also had Müllerian anomalies. CONCLUSION: Gynecologic evaluation should be a part of medical care for females with RSTS, particularly in individuals with delayed menarche or abnormal menstrual history, on the basis of the observed association between RSTS and Müllerian anomalies in this case series. Although several candidate genes and copy number variants are associated with MRKH, no candidate genes in close proximity to the 16p13.3 region have been identified to explain both RSTS and MRKH in the index patient. Due to the regulatory nature of CREBBP during embryonic development, we theorize that CREBBP may play a role in the migration of Müllerian structures during embryogenesis.

RESUMO

STUDY OBJECTIVE: To describe the long-term anatomic and sexual functional results of vaginoplasty with acellular dermal matrix (ADM) in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) and to evaluate the changes in body image pre- and postoperatively in these patients. DESIGN: A retrospective study from March 2015 to September 2021. SETTING: A tertiary teaching hospital. PATIENTS: Forty-two patients with MRKH syndrome who underwent vaginoplasty with ADM (the MRKH group) and 30 sexually active, nulliparous, aged-matched women (the control group). INTERVENTION: The relevant data were retrospectively collected via our electronic medical record system and were analyzed statistically. MEASUREMENTS AND MAIN RESULTS: Vaginal length was assessed using a 3-cm-diameter mold. The Chinese version of the Female Sexual Function Index questionnaire was used to evaluate sexual function. The Chinese version of the modified body image scale was applied to evaluate body image. The median follow-up time was 57 months (range, 13-91 months). Granulomatous polyps in the neovagina were the most common postoperative complication (7 of 42, 16.7%). Patients with MRKH syndrome can achieve long-term satisfactory outcomes both anatomically and functionally after vaginoplasty with ADM, comparable with those of healthy control women. The vaginal length in the MRKH group was comparable to that in the control group ( 8.04 ± 0.51 cm vs. 8.15 ± 0.46 cm, respectively). The FSFI scores were similar between the MRKH (26.54 ± 3.44) and control (26.80 ± 2.23) groups. The modified body image scale score was significantly decreased after vaginoplasty with ADM. CONCLUSION: Vaginoplasty with ADM is a minimally invasive and effective procedure for patients with MRKH syndrome.

RESUMO

PURPOSE: Various techniques for neovaginal construction have been employed in the pediatric and adult populations, including the use of intestinal segments, buccal mucosal grafts, and skin grafts. Small intestinal submucosa (SIS) extracellular matrix grafts have been described as a viable alternative, though prior experience is limited. Our purpose was to assess operative characteristics and patient outcomes with neovaginal construction using SIS grafts. METHODS: Thirteen patients underwent vaginoplasty with acellular porcine SIS grafts at our institution between 2018 and 2022. Operative and clinical data, postoperative mold management, vaginal dilating length, and complications were reviewed. RESULTS: Age at time of repair ranged from 13 to 30 years (median 19 years). Patient diagnosis included cloacal anomalies (n = 4), Mayer-Rokitansky-Küster-Hauser syndrome (n = 4), isolated vaginal atresia with or without a transverse vaginal septum (n = 4), and vaginal rhabdomyosarcoma requiring partial vaginectomy (n = 1). Following dissection of the neovaginal space, a silicon mold wrapped with SIS graft was placed with retention sutures and removed on postoperative day 7. Median (IQR) operative time was 171 (118-192) minutes, estimated blood loss was 10 (5-20) mL, and length of stay was 2 (1-3) days. The follow-up period ranged from 3 to 47 months (median 9 months). Two patients developed postoperative vaginal stenosis that resolved with dilation under anesthesia. Mean vaginal length on latest follow-up was 8.97 cm. All thirteen patients had successful engraftment and progressed to performing self-dilations or initiating intercourse to maintain patency. There were no cases of graft reaction or graft extrusion. CONCLUSIONS: We conclude that acellular small intestinal submucosa grafts are effective and safe alternatives for mold coverage in neovaginal construction. Our experience demonstrates minimal perioperative morbidity, early mold removal, and progression to successful dilation with maintenance of a functional vaginal length. Future study on sexual outcomes, patient satisfaction, and comparison against alternative techniques has been initiated. LEVEL OF EVIDENCE: IV. TYPE OF STUDY: Retrospective Study.

RESUMO

BACKGROUND: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a severe congenital disorder characterized by vaginal hypoplasia caused by dysplasia of the Müllerian duct. Patients with MRKH syndrome often require nonsurgical or surgical treatment to achieve satisfactory vaginal length and sexual outcomes. The extracellular matrix has been successfully used for vaginal reconstruction. METHODS: In this study, we developed a new biological material derived from porcine vagina (acellular vaginal matrix, AVM) to reconstruct the vagina in Bama miniature pigs. The histological characteristics and efficacy of acellularization of AVM were evaluated, and AVM was subsequently transplanted into Bama miniature pigs to reconstruct the vaginas. RESULTS: Macroscopic analysis showed that the neovaginas functioned well in all Bama miniature pigs with AVM implants. Histological analysis and electrophysiological evidence indicated that morphological and functional recovery was restored in normal vaginal tissues. Scanning electron microscopy showed that the neovaginas had mucosal folds characteristics of normal vagina. No significant differences were observed in the expression of CK14, HSP47, and α-actin between the neovaginas and normal vaginal tissues. However, the expression of estrogen receptor (ER) was significantly lower in the neovaginas than in normal vaginal tissues. In addition, AVM promoted the expression of ß-catenin, c-Myc, and cyclin D1. These results suggest that AVM might promotes vaginal regeneration by activating the ß-catenin/c-Myc/cyclin D1 pathway. CONCLUSION: This study reveals that porcine-derived AVM has potential application for vaginal regeneration.

RESUMO

The objective of this study was to explore the personal experience of women with MRKH, a rare condition characterised by congenital abnormalities of the genital tract. There are very few qualitative studies into the lived experiences of women with MRKH. Interviews were conducted with 13 women with MRKH and analysed using interpretative phenomenological analysis. Four superordinate themes are discovered: maintaining a viable female identity; acceptance and coping; normality, secrecy and shame and the isolating impact of a lack of knowledge amongst the medical profession. This study also suggests that societal ideals of a 'normal woman' are influencing how MRKH impacts on the self-experienced psychological health. It is suggested that the psychological wellbeing of women with MRKH could be improved with continued multidisciplinary support beyond the initial diagnosis and alongside any vaginal correction.

RESUMO

We performed a genetic investigation into the case of an inherited Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Our patients were an adolescent and her mother, both with MRKH syndrome. The delivery of a biological offspring was achieved via a gestational carrier. Karyotype and exome sequencing were used to complete a three-generation genetic analysis of the family. Both the mother and her daughter harbored a deletion of 4 Mb at the locus of 2q37, a syndrome rarely described in association with MRKH. No pathogenic single-nucleotide variant relevant to the phenotype was found. The deletion was not inherited from either parent of the mother. In addition, some physical findings suggesting 2q37 deletion syndrome were found in our patients. We conclude that when combined with the use of a gestational carrier or uterine transplantation, the identification of a genetic cause for MRKH may enable the application of preimplantation genetic testing on embryos, thus potentially averting the transmission of the genetic anomaly to subsequent generations.

RESUMO

BACKGROUNDS: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a severe congenital malformation of the female genital tract, is a highly heterogeneous disease which has no clear etiology. Previous studies have suggested that copy number variations (CNVs) and single-gene mutations might contribute to the development of MRKH syndrome. In particular, deletions in 16p11.2, which are suggested to be involved in several congenital diseases, have been reported in Chinese type II MRKH patients and European MRKH patients. However, few CNVs including 16p11.2 microdeletions were identified in Chinese type I MRKH cases although it accounted for the majority of MRKH patients in China. Thus, we conducted a retrospective study to identify whether CNVs at human chromosome 16p11.2 are risk factors of type I MRKH syndrome in the Chinese Han population. METHODS: We recruited 143 patients diagnosed with type I MRKH between 2012 and 2014. Five hundred unrelated Chinese without congenital malformation were enrolled in control group, consisting of 197 from the 1000 Genomes Project and 303 from Fudan University. Quantitative PCR, array comparative genomic hybridization, and sanger sequencing were conducted to screen and verify candidate variant. RESULTS: Our study identified recurrent 16p11.2 microdeletions of approximately 600 kb in two out of the 143 type I MRKH syndrome patients using high-density array-based comparative genomic hybridization (aCGH), while no 16p11.2 deletion was found in the control group. We did not find any mutations in TBX6 gene in our samples. CONCLUSIONS: The results of the study identify 16p11.2 deletion in Chinese MRKH I patients for the first time, as well as support the contention that 16p11.2 microdeletions are associated with MRKH syndrome in both types across populations. It is suggested that 16p11.2 microdeletions should be included in molecular diagnosis and genetic counseling of female reproductive tract disorders.

RESUMO

BACKGROUND: Aromatase deficiency is a rare disorder, with only a few cases reported in India. We describe a single-center experience in western India, with a systematic review of genetically proven 46,XX aromatase deficiency patients to evaluate hormonal parameters. METHODS: Retrospective review of case records, collating phenotypic and genotypic data and molecular modeling. Systematic review of 46,XX aromatase deficiency, analyzing data on gonadotropins, estrogen and androgens. RESULTS: In the seven patients from our center, presentation was frequent in childhood or adolescence (4/7: delayed puberty or hyperandrogenism), with maternal virilization (4/7), predominance of Prader III/IV (5/7), and initial rearing as females (6/7). Three patients had hypoplastic ovaries. One patient had spontaneous regular menses. We report three novel (p.Arg115Pro, p.Arg192Pro, and c.145+1_145+4delins) and two recurrent variants (p.Val370Met, and c.145+1_145+4delins) in western and northern India, respectively. On systematic review (n=43), gonadotropins were elevated (FSH>LH) across ages (except preterm infants), androgens were elevated in about one-third of cases during childhood and puberty, and estradiol was lower than in controls in mini-puberty and puberty. Spontaneous thelarche and streak ovaries were significantly more frequent in patients with non-truncating and truncating variants, respectively. CONCLUSION: We report uncommon presentations with possible founder variants, and highlight hormonal parameters across ages. Serum FSH levels were elevated except in preterms, and can be used as a diagnostic marker.

RESUMO

PURPOSE: This systematic review aims to provide a data synthesis about the risk of neovaginal cancer in women with Müllerian anomalies and to investigate the association between the adopted reconstructive technique and the cancer histotype. METHODS: PubMed, MEDLINE, Embase, Scopus, ClinicalTrials.gov and Web of Science databases were searched from inception to March 1st, 2023. Studies were included if: (1) only women affected by Müllerian malformations were included, (2) the congenital defect and the vaginoplasty technique were clearly reported, (3) the type of malignancy was specified. RESULTS: Literature search yielded 18 cases of squamous cell carcinoma and two cases of vaginal intraepithelial neoplasia 3 (VAIN 3). Of these, 3 had been operated on according to the Wharton technique, 8 according to the McIndoe technique, 3 with a split-skin graft vaginoplasty, 2 according to the Davydov technique, 2 with a simple cleavage technique, 1 according to the Vecchietti technique and 1 with a bladder flap vaginoplasty. A total of 17 cases of adenocarcinoma and 1 case of high-grade polypoid dysplasia were also described. Of these, 15 had undergone intestinal vaginoplasty, 1 had been operated on according to the McIndoe technique and 1 had undergone non-surgical vaginoplasty. Finally, 1 case of verrucous carcinoma in a woman who had undergone a split-skin graft vaginoplasty, was reported. CONCLUSION: Although rare, neovaginal carcinoma is a definite risk after vaginal reconstruction, regardless of the adopted technique. Gynaecologic visits including the speculum examination, the HPV DNA and/or the Pap smear tests should be scheduled on an annual basis.

RESUMO

INTRODUCTION AND HYPOTHESIS: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a condition with an underdeveloped or absent vagina and uterus due to embryological growth failure of the Müllerian ducts. Many techniques have been described to construct a neovagina with an acceptable depth that allows penetrative intercourse. This is a step-by-step video tutorial on the Wharton-Sheares-George surgical technique for vaginoplasty in patients with MRKH syndrome. METHOD: With Wharton-Sheares-George vaginoplasty, the rudimentary Müllerian ducts are incrementally dilated by pushing Hegar dilators in the direction of the pelvic axis, and the resulting median raphe is then intersected using diathermy. As a result, a neovagina is created and an estriol-coated vaginal mold is inserted for 3 days. The patient receives comprehensive discharge instructions, a self-dilation program three times a day, and a monthly follow-up. RESULTS: A 3-month follow-up showed a high subjective degree of satisfaction with surgery and sexual satisfaction in both patients. CONCLUSION: Wharton-Sheares-George vaginoplasty is a safe and efficient technique for creating a neovagina for patients with MRKH syndrome.

RESUMO

OBJECTIVE: To summarize the available evidence on the laparoscopic Davydov and Vecchietti methods to create a neovagina and to compare these techniques with a focus on neovaginal length, sexual function, operative time, and complications. DESIGN: A systematic electronic search up to August 2022 using PubMed and Embase is performed. SETTING: Not applicable. PATIENTS: Women with Mayer-Rokistansky-Küster-Hauser syndrome. INTERVENTIONS: All published clinical studies concerning the laparoscopic Davydov and laparoscopic Vecchietti procedures as a surgical technique to create a neovagina in women with Mayer-Rokistansky-Küster-Hauser syndrome were obtained. The guidelines for the preferred reporting items for systematic reviews and meta-analysis were followed. The following data were extracted: operative time, hospital stay, major early complications (within 3 months postsurgery), dilation therapy, neovaginal length, vaginal discharge, vaginal stenosis, time to sexual activity, sexual satisfaction, penetrative sexual activity, dyspareunia, score on the Female Sexual Function Index (FSFI), and duration of follow-up. The Newcastle Ottawa Scale was used to assess the quality of articles. MAIN OUTCOME MEASURES: Neovaginal length, FSFI scores, operative time, and complications. RESULTS: A total of 1,163 articles were identified, of which 33 studies were included in this systematic review. Of these, 12 studies (380 patients) are related to the Davydov method, 19 studies (1,126 patients) to the Vecchietti method, and 2 articles concern both. There is clinical heterogeneity and variety in the quality of the studies. Eighteen studies were included in the meta-analyses. The mean neovaginal length 12 months after the Davydov method is 8.3 cm (95% confidence interval [CI] 8.1-8.6), vs. 8.7 cm (95% CI 7.2-10.3) after the Vecchietti method. The mean FSFI score after the Davydov method is 28.9 (95% CI 26.8-31.1), compared with 27.5 (95% CI 25.0-30.1) after the Vecchietti method. The operative time of the Davydov method is 126 minutes (95% CI 109-143), compared with 40 minutes (95% CI 35-45) of the Vecchietti method. CONCLUSIONS: The operations yield comparable neovaginal length, sexual function, and complication rates. The mean FSFI scores indicate no sexual dysfunction in either group. The operative time of the Davydov method is significantly longer. There is no superiority shown for one of the surgical techniques in functional terms.

RESUMO

BACKGROUND: In the past, the primary treatment for MRKH syndrome (Mayer-Rokitansky-Küster-Hauser syndrome) with a functional primordial uterus was surgical removal of the functional primordial uterus. In rare instances, the endometrium of the functional primordial uterus is well developed, and surgical preservation of the functional primordial uterus provides the possibility of preserving reproductive function for these patients. CASE PRESENTATION: A 14-year-old female was diagnosed with type I MRKH syndrome with a functional primordial uterus through physical examination and imaging investigations. We freed the functional primordial uterus through laparoscopic surgery and excised a portion of the lower myometrium to create an outlet at a lower uterine segment, which we then intermittently anastomosed to the tip of the artificial vagina. The patient recovered well after the surgery, and a re-examination showed no significant abnormalities. CONCLUSION: We were successful in preserving the functional primordial uterus using laparoscopic surgery in a patient with MRKH syndrome and connecting it to an artificial vagina through reconstructive surgery to ensure unobstructed menstrual drainage and preserve the reproductive potential of the patient.

RESUMO

OBJECTIVE: To better understand patients' conditions and expectations before starting a uterus transplantation (UTx) program for women suffering from Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome). METHOD: A web-based survey was conducted among MRKH patients via the French national association network from March to August 2020. The questionnaire comprised twenty-eight questions about their desire for parenthood, their condition's characteristics and previous reconstructive procedures, opinions and knowledge about UTx. RESULTS: Among the 148 participants, 88 % reported a desire for parenthood, and 61 % opted for UTx as their first choice to reach this aim. The possibility of bearing a child and having the same genetic heritage were the main motivations. Once informed about the usual course of an UTx protocol, only 13 % of the participants changed their mind and 3 out of 4 of them opted for UT. CONCLUSION: Uterus transplantation seems to be the first option to reach motherhood in patients suffering from MRKH syndrome. The development of UTx programs could meet the demands of this already well-informed population.

RESUMO

BACKGROUND: Bowel vaginoplasty is a surgical method for neovagina construction that, despite its advantages over other techniques, is still burdened by complications such as prolapse. The incidence of sigmoid neovagina prolapse (SNP) is difficult to determine, and there are no evidence-based recommendations for treatment. We present a case of SNP and a systematic review of previous cases. CASE: A 73-year-old woman presented with stage III prolapse of her sigmoid neovagina constructed 51 years prior. Dynamic pelvic MRI revealed that the majority of the prolapse was due to the mucosa's loss of support. Due to the presence of numerous pelvic adhesions, an alternative to the laparoscopic approach was evaluated by a multidisciplinary team which led to the patient being treated using a modification of Altemeier's procedure. SYSTEMATIC REVIEW: After PROSPERO Registration (CRD42023400677), a systematic search of Medline and Scopus was performed using specific search terms. Study metadata including patient demographics, prolapse measurements, reconstruction techniques, recurrence rates, and timing were extracted. Fourteen studies comprising 17 cases of SNP were included. Vaginal resection of the redundant sigmoid, comprising Altemeier's procedure, was the most definitive surgery, but it was also associated with recurrences in three cases. Laparoscopic sacropexy was the second most definitive surgery with no recurrence reported. CONCLUSION: Our review shows that the recurrence after correction of sigmoid neovagina prolapses is higher than previously reported. Laparoscopy colposacropexy appeared to be the best approach, but it's not always feasible. In these scenarios, a mucosal resection using the Altemeier's procedure is the most effective surgery.

RESUMO

OBJECTIVE: To describe surgical correction of vaginal agenesis via a modified laparoscopic Vecchietti procedure with the goal of disseminating knowledge and improving surgical technique CASE: An 18-year-old female presented with primary amenorrhea, age-appropriate secondary sex characteristics, a shallow vagina, and 46,XX karyotype. Imaging showed rudimentary uterine horns and normal ovaries, kidneys, and spine. Diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome type I was made. After an unsuccessful attempt at vaginal dilation and extensive counseling, the patient chose to have a laparoscopic Vecchietti procedure. Vecchietti vaginoplasty eliminates the need for grafts and creates a neovagina with accelerated vaginal dilation by stretching the introital mucosa with a spring mechanism. RESULTS: A modified laparoscopic Vecchietti procedure was performed. Postoperatively, daily suture adjustments were made. When the device was removed after 7 days, the examination revealed a 9-cm vaginal canal, which was maintained with self-dilation.

RESUMO

OBJECTIVE: In patients with Rokitansky syndrome, vaginal agenesis can be treated using various surgical techniques, and various factors can affect each surgery outcome in the long term. This meta-analysis aimed to evaluate sexual function outcomes in patients with Rokitansky syndrome after various surgery techniques. DATA SOURCES: Searches were conducted in Google Scholar, PubMed, Cochrane database, ScienceDirect, Web of Science, and ClinicalTrials.gov. Systematic searches were conducted on studies published until November 2022 (CRD42022370735). METHODS OF STUDY SELECTION: During the first stage of database scanning and reference check, 1820 results were identified, and an evaluation of the total 10 studies was finally conducted. The inclusion criteria involved selecting randomized controlled trials that focused on assessing sexual function after surgical treatment in patients of all ages with Rokitansky syndrome. TABULATION, INTEGRATION, AND RESULTS: EndNote version 20 software was used to organize and identify duplicate articles through screening. The Joanna Briggs Institute's critical appraisal tool was used to evaluate each study's quality for bias potential. The results showed that the total scores of female sexual functions in patients with Rokitansky syndrome after vaginoplasty were significantly lower than in healthy women (standardized mean difference, -0.233; p <.05; range, -0.376 to -0.090). The 6-domain analysis of the Female Sexual Function Index questionnaire revealed that lubrication (p <.05) and satisfaction (p <.05) were significantly lower in patients undergoing vaginoplasty. CONCLUSION: All surgical techniques to create a neovagina for patients with Rokitansky syndrome have successfully affected the sexual function outcomes. Considering all other factors affecting sexual function outcomes in the long term, more quantitative and qualitative studies are needed to assess sexual satisfaction in patients treated with surgical techniques.
