Nonpuerperal uterine inversion caused by an adenosarcoma: A case report.

INTRODUCTION: Eighty-five per cent of uterine inversions are puerperal. Non-puerperal uterine inversion is usually caused by tumours that exert a traction force on the fundus of the uterus. This causes the uterus to be partially or completely inverted. It is commonly related to benign tumours like submucosal leiomyomas. Nevertheless, malignancies are an infrequent association. CASE PRESENTATION: We report a case of a 35-year-old female patient, medically and surgically free, gravida0 para0, complaining of menometrorrhagia associated with pelvic pain for 2 years. A suprapubic ultrasound scan showed an enlarged, globular uterus with a heterogeneous, undefined mass of 49 mm in size. MRI scan showed the appearance of a U-shaped uterine cavity and a thickened inverted uterine fundus with an endometrial infiltrating mass of 25 mm. Intraoperative exploration showed uterine inversion involving the ovaries; the fallopian tubes and the round ligaments and a necrotic intracavitary mass. The malignancy of the tumor was confirmed through anatomopathological examination as Adenosarcoma. CONCLUSIONS: Uterine inversion is rare outside the puerperal period, and malignant etiology must not be overlooked. Therefore, comprehensive care with meticulous etiological investigation is crucial.

Peripartal management of dichorial twin pregnancy in a bicornuate bicollis uterus: a case report and review of the literature.

INTRODUCTION: The management of a pregnancy in a bicornuate uterus is particularly challenging. A bicornuate uterus is a rare occurrence and a twin pregnancy in a bicornuate uterus even more rare. These pregnancies call for intensive diagnostic investigation and interdisciplinary care. CASE PRESENTATION: We report on a 27-year-old European woman patient (gravida I, para 0) with a simultaneous pregnancy in each cavity of a bicornuate bicollis uterus after embryo transfer. The condition was confirmed by hysteroscopy and laparoscopy. Several unsuccessful in vitro fertilization (IVF) attempts had been performed earlier before embryo transfer in each cornus. After a physiological course of pregnancy with differential screening at 12 + 6 weeks and 22 + 0 weeks of gestation, the patient presented with therapy-resistant contractions at 27 + 2 weeks. This culminated in the uncomplicated spontaneous delivery of the leading fetus and delayed spontaneous delivery of the second fetus. DISCUSSION: Only 16 cases of twin pregnancy in a bicornuate unicollis uterus have been reported worldwide and only 6 in a bicornuate bicollis uterus. The principal risks in such pregnancies are preterm labor, intrauterine growth restriction, malpresentation and preeclampsia. These typical risk factors of a twin pregnancy are greatly potentiated in the above mentioned setting. CONCLUSION: A twin pregnancy in the presence of a uterine malformation is rare and difficult to manage. These rare cases must be collected and reported in order to work out algorithms of monitoring and therapy as well as issue appropriate recommendations for their management.

Spontaneous uterine rupture with amniotic sac protrusion during the third trimester of a unicornuate uterus pregnancy: A rate case report.

RATIONALE: Uterine rupture is an obstetrical emergency associated with severe maternal and fetal mortality. It is rare in the unscarred uterus of a primipara. PATIENT CONCERNS: A 25-year-old woman in her 38th week of gestation presented with slight abdominal pain of sudden onset 10 hours before. An emergency cesarean section was done. After surgery, the patient and the infant survived. DIAGNOSES: With slight abdominal pain of clinical signs, ultrasound examination showed that the amniotic sac was found in the peritoneal cavity with a rupture of the uterine fundus. INTERVENTIONS: Uterine repair and right salpingectomy. OUTCOMES: After surgery, the patient and the infant survived. The newborn weighed 2600 g and had an Apgar score of 10 points per minute. Forty-two days after delivery, the uterus recovered well. LESSONS: Spontaneous uterine rupture should be considered in patients even without acute pain, regardless of gestational age, and pregnancy with abdominal cystic mass should consider the possibility of uterine rupture.

Herlyn–Werner–Wünderlich syndrome: A case series / Síndrome de Herlyn-Werner-Wünderlich: una serie de casos

Introduction: Herlyn–Werner–Wünderlich syndrome is a uterine malformation characterized by uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis. Clinical findings: The manifestation of the disease is widely diverse; it is usually diagnosed after menarche, with dysmenorrhea and abnormal uterine bleeding; it is also associated with infertility. Main diagnosis: Four clinical cases, their diagnosis are reported here. Therapeutic interventions and results: The treatment and results of these four patients are described here. Conclusion: When studying uterine malformation it is important to consider this rare disease to avoid possible complications and giving the patient a correct diagnose and treatment. The hysteroscopy resection of the longitudinal vaginal septum in those symptomatic patients with hematocolpos should be considered as a good option for treatment.(AU)

Introducción: El síndrome de Herlyn-Werner-Wünderlich es una malformación uterina que asocia útero didelfo, hemivagina obstruida total o parcialmente y agenesia renal ipsilateral. Hallazgos clínicos: La clínica que presenta este síndrome es muy diversa; se suele diagnosticar después de la menarquia cursando con dismenorrea y sangrado uterino anómalo; así mismo se asocia a infertilidad. Diagnósticos principales: Se presentan a continuación 4 casos clínicos, su diagnóstico y tratamiento mediante diversas técnicas. Intervenciones terapéuticas y resultados: Se describen en este manuscrito los tratamientos aplicados a estas pacientes y sus resultados. Conclusión: Ante el hallazgo de una malformación uterina es importante tener en cuenta esta entidad infrecuente, para evitar posibles complicaciones y proporcionar a la paciente un diagnóstico y tratamiento correctos. La resección histeroscópica del tabique vaginal longitudinal en aquellas pacientes sintomáticas con hematocolpos debe ser considerada como una buena opción de tratamiento.(AU)

Retroperitoneal 'uterus-like mass' of cervical origin.

We report a rare case of a retroperitoneal uterus-like mass communicating with the endocervix, which presented as abdominal pain and bloating associated with severe irregular vaginal and postcoital bleeding. Our patient did not have any structural abnormalities of the urogenital system or otherwise, which makes a müllerian defect unlikely in our case. Based on the diagnostic criteria for the choristoma, that theory would be excluded here as the mass communicated with the endocervix. This strengthens the theory of metaplasia, under the effect of oestrogen and accelerated by the hyperoestrogenic state of pregnancy as the most likely postulate for our patient. Although the uterus-like mass is not commonly reported, it should be considered as a possible differential for pelvic masses.

Hysteroscopic Metroplasty Using Holmium: YAG Laser for Treatment of Septate Uterus.

STUDY OBJECTIVE: To demonstrate the safety, efficacy, and ease of hysteroscopic metroplasty using holmium:YAG (Ho:YAG) laser for treatment of septate uterus. DESIGN: Stepwise demonstration of surgical technique with narrated video footage. SETTING: Septate uterus is the most common type of uterine anomaly. The incidence of uterine septum in women presenting with infertility and recurrent abortions is 15.4% [1,2]. Hysteroscopic septal incision is associated with improvement in live-birth rate in these women [3]. Hysteroscopic metroplasty for septate uterus can be done with the use of scissors and energy sources such as monopolar and bipolar electrosurgery and lasers. Ho:YAG laser is commonly used by urologists for various surgeries because of its "Swiss Army Knife" action of cutting, coagulation, and vaporization [4]. Ho:YAG laser is known for its precision. It causes lesser depth of tissue injury and necrosis and minimal collateral thermal damage compared with the electrosurgical devices and other lasers used for hysteroscopic surgery [5-8]. This is advantageous in hysteroscopic metroplasty given that it reduces the risk of uterine perforation during surgery and hence uterine rupture in the subsequent pregnancy. Reduced collateral damage to the surrounding endometrium helps promote early endometrial healing and prevent postoperative intrauterine adhesions. A 28-year-old patient with history of 2 spontaneous abortions came to our hospital for investigations. 3D transvaginal sonography of the patient showed presence of partial septate uterus with a fundal indentation of 1.5 cm (Supplemental video 1). INTERVENTION: Diagnostic hysteroscopy followed by septal incision using Ho: YAG laser was planned. We used a 2.9 mm BETTOCCHI Hysteroscope (Karl Storz SE & Co.) with a 5 mm operative sheath. Normal saline was used as the distending medium and the intrauterine pressure was maintained at 80 to 100 mm Hg. The procedure was done under total intravenous anesthesia using propofol injection. Vaginoscopic entry into the uterus (without any cervical dilatation) showed evidence of a partial uterine septum with tubal ostia on either side of the septum. A 400 micron quartz fiber was passed through a laser guide into the 5-Fr working channel of the operative hysteroscope. Ho:YAG laser (Auriga XL 50-Watt, Boston Scientific) with power settings of 15 watts (1500 mJ energy at 10 Hz) was used. Incision of the septum was started at the apex of the septum in the midline and continued in a horizontal manner from side to side toward the base (Supplemental video 2). Incision of the septum is continued till the tip of the hysteroscope can move freely from one ostium to the other (Supplemental video 3). The operative time was 12 minutes. There were no intra- or postoperative complications. Postoperative estrogen therapy was given for 2 months in the form of estradiol valerate 2 mg (tablet, Progynova, Zydus Cadila) 12 hourly orally for 25 days and medroxyprogesterone acetate 10 mg (tablet, Meprate, Serum Institute of India, Ltd) 12 hourly orally added in the last 5 days [9]. 3D transvaginal ultrasound was done on day 8 of menses. It showed a triangular uterine cavity with a very small fundal indentation of 0.37 cm. A second look hysteroscopy that was done on day 9 of menses showed an uterine cavity of good shape and size [10]. Few fundal adhesions were seen and they were incised using Ho:YAG laser. The patient conceived 5 months after the primary surgery and delivered by cesarean section at 38 weeks, giving birth to a healthy baby of 2860 grams. There were no complications during her pregnancy and delivery. A comparative study is essential to prove its advantages over other energy sources for this surgery. CONCLUSION: Hysteroscopic metroplasty using Ho:YAG laser for treatment of septate uterus is a simple, precise, safe, and effective procedure. VIDEO ABSTRACT.

Evaluation of Recurrent Pregnancy Loss.

Recurrent pregnancy loss (RPL) affects approximately 5% of couples. Although RPL definitions vary across professional societies, an evaluation after a second clinically recognized first-trimester pregnancy loss is recommended. Good quality evidence links parental chromosomal rearrangements, uterine anomalies, and antiphospholipid syndrome (APS) to RPL. In contrast, the relationship between RPL and other endocrine, hematologic, and immunologic disorders or environmental exposures is less clear. Anticoagulant therapy and low-dose aspirin are recommended for patients with RPL who have also been diagnosed with APS. Vaginal progesterone supplementation may be considered in patients experiencing vaginal bleeding during the first trimester. Surgical correction may be considered for patients with RPL in whom a uterine anomaly is identified. Evaluation and management of additional comorbidities should be guided by the patient's history rather than solely based on the diagnosis of RPL, with the goal of improving overall health to reduce complications in the event of pregnancy. Most people with RPL, including those without identifiable risk factors, are expected to achieve a live birth within 5 years from the initial evaluation. Nevertheless, clinicians should be sensitive to the psychological needs of individuals with this condition and provide compassionate and supportive care across all stages.

Successful pneumovaginoscopic surgery for recurrent abscess of OHVIRA syndrome, preventing further recurrence and subsequent pregnancy.

INTRODUCTION: OHVIRA syndrome is a rare congenital anomaly of Müllerian duct development characterized by uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. The primary treatment is surgical excision of the obstructed hemivaginal septum and hematometrial drainage. In recent years, minimally invasive approaches such as hysteroscopic or vaginoscopic septum resection have been reported. Furthermore, we originally developed some novel pneumovaginoscopic gynecologic surgeries for years using a device that consists of a cylinder that fits into the vagina and a lid that mounts multiple ports, allowing the vagina to be dilated with carbon dioxide gas, similar to a single-port laparoscope. MATERIALS AND SURGICAL TECHNIQUE: We report a successful pneumovaginoscopic surgery for a complicated recurrent abscess in a patient with OHVIRA syndrome. Conventional surgery was performed with a single forceps in a liquid, as in cystoscopy or hysteroscopy. However, this new surgery allowed multiple forceps in a gas, as in laparoscopy. So pus and blood were aspirated and washed away without leaking into the abdominal cavity via fallopian tubes. The surgical smoke generated by thermal coagulation also aspirated to clean the field of vision immediately. And thick, complicated abscesses were drained successfully. The patient conceived through IVF with ICSI and delivered safely at full term. DISCUSSION: Pneumovaginoscopy could benefit complex vaginal surgery cases, such as abscess formation in patients with OHVIRA syndrome.

Impact of congenital uterine anomalies on reproductive outcomes of IVF/ICSI-embryo transfer: a retrospective study.

OBJECTIVE: To study the impact of congenital uterine anomalies on reproductive outcomes after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-embryo transfer (ET). METHODS: A retrospective study including a total of 865women with congenital uterine anomalies and 865 age and admission time matched controls who underwent the first IVF/ICSI-ET cycle between January 2010 and December 2019 was conducted. Women with uterine anomalies were classified into canalization defect (complete septate uterus and subseptate uterus) and unification defect (unicornuate uterus, bicornuate uterus, and didelphus uterus) according to the processes of abnormal embryological development. Control women were selected by age (± 1.0 year) and admission time (± 6 months) matched with a 1:1 ratio. The reproductive outcomes were compared between women with uterine anomalies and the controls. The primary outcome was live birth; secondary outcomes were clinical pregnancy, ectopic pregnancy, preterm delivery, and spontaneous pregnancy loss. RESULTS: Compared with women with a normal uterus, women with canalization defects were less likely to experience live birth [84/332 (25.3%) vs 128/332 (38.6%), RR: 0.647, 95% CI 0.513-0.815, P < 0.001]. They also had a lower clinical pregnancy rate [126/332 (38.0%) vs 206/332 (62.0%), RR: 0.829, 95% CI 0.690-0.997, P = 0.046] and experienced a higher first-trimester pregnancy loss rate [25/126 (19.8%) vs 11/206 (5.3%), RR: 2.716, 95% CI 1.393-5.295, P = 0.003]. Compared with women with a normal uterus, women with a unification defect were also less likely to experience live birth [132/533 (24.8%) vs 219/533 (41.1%), RR: 0.713, 95% CI 0.586-0.868, P = 0.001]. Women with a unification defect had lower clinical pregnancy rates [182/533 (34.1%) vs 263/533 (49.1%), RR: 0.813, 95% CI 0.695-0.952, P = 0.010] and increased first-trimester pregnancy loss [36/182 (19.8%) vs 20/263 (7.6%), RR: 3.288, 95% CI 1.776-6.085, P < 0.001]. While uterine anomaly seemed not increase the risk of preterm birth, ectopic pregnancy and second-trimester pregnancy loss. CONCLUSIONS: Both canalization defects and unification defects were associated with lower fertility outcomes, including lower live birth rates, lower clinical pregnancy rates, and higher early miscarriage rates.

Evaluating resectoscopy and the levonorgestrel intrauterine system for intermenstrual bleeding associated with cesarean scar defects: A retrospective study of treatment outcomes.

AIM: To compare and evaluate the efficacy of the levonorgestrel-releasing intrauterine system (LNG-IUD) and resectoscopy remodeling procedure for intermenstrual bleeding associated with previous cesarean delivery scar defect (PCDS). METHODS: A retrospective comparative study was conducted on patients with PCDS receiving LNG-IUD (levonorgestrel 20 µg/24 h, N = 33) or resectoscopy remodeling (N = 27). Treatment outcomes were compared over 1, 6, and 12 months. Outcomes in patients with a retroverted or large uterus size, defect size, and local vascularization also were evaluated. RESULTS: At 12 months post-treatment, there were no significant differences between groups in efficacy rate; however, the reduction of intermenstrual bleeding days was higher in the LNG-IUD group than in the resectoscopy group (13.6 vs. 8.5 days, p = 0.015). Within the first year, both groups experienced a reduction in bleeding days, but the decrease was greater in the LNG-IUD group. Individuals exhibiting increased local vascularization at the defect site experienced more favorable outcomes in the LNG-IUD group than the resectoscopy group (p = 0.016), and who responded poorly tended to have a significantly larger uterus in the LNG-IUD group (p = 0.019). No significant differences were observed in treatment outcomes for patients with a retroverted uterus or large defect in either group. CONCLUSIONS: Our findings support that the LNG-IUD is as effective as resectoscopy in reducing intermenstrual bleeding days associated with PCDS and can be safely applied to patients without recent fertility aspirations. Patients with increased local vascularization observed during hysteroscopy may benefit more from LNG-IUD intervention than resectoscopy.

Long-term health-related quality-of-life and psychosocial outcomes after uterus transplantation: a 5-year follow-up of donors and recipients.

STUDY QUESTION: What are the outcomes regarding health-related quality-of-life, mood, and marital relationship of recipients and donors 5 years after uterus transplantation (UTx) and uterus donation? SUMMARY ANSWER: Both recipients and donors generally demonstrated long-term stability regarding psychosocial outcomes but with negative deviations associated with unsuccessful outcomes. WHAT IS KNOWN ALREADY: UTx is the first infertility treatment for women with absolute uterine factor infertility. The procedure can be performed with either a uterus donation from a live donor (LD), typically a close relative, or from a deceased, multi-organ donor. There are many potential stressful events over several years after UTx both for recipients and for LDs and these events may have impacts on quality-of-life and mental well-being. STUDY DESIGN, SIZE, DURATION: This, prospective observational cohort study includes the nine recipients and LDs of the first human UTx trial. They were assessed in 2017-2018 by questionnaires 5 years after UTx. PARTICIPANTS/MATERIALS, SETTING, METHODS: The nine recipients (ages 32-43 years) and their respective LDs (ages 44-67 years) were either related (n = 8) or friends (n = 1). Eight recipients had congenital uterine absence and one was hysterectomized due to cervical cancer. For two recipients, UTx resulted in early graft failures, while six of the other seven recipients gave birth to a total of eight babies over the following 5 years. Physical and mental component summaries of health-related quality-of-life were measured with the SF-36 questionnaire. Mood was assessed by the Hospital Anxiety and Depression Scale. Relationship with partner was measured with the Dyadic Adjustment Scale. Comparisons were made between the values after 5 years and the values before uterus donation/transplantation. MAIN RESULTS AND THE ROLE OF CHANCE: Five years after primary UTx, the majority of recipients scored above the predicted value of the general population on quality-of-life, except for two women, one of whom had a viable graft but no live birth and one recipient who was strained by quality-of-life changes, possibly related to parenthood transitions. Regarding mood, only one value (anxiety) was above the threshold for further clinical assessment. Recipients showed declining satisfaction with their marital relationships, but all reported scores above the 'at risk for divorce' threshold at the time of the final assessment in our study. The LDs were all found to be stable and above the predicted value of the general population regarding mental components of quality-of-life. Three LDs showed declined physical components, possibly related to older age. Only one LD reported a value in mood (anxiety) that would need further assessment. The marital satisfaction of LDs remained stable and unchanged compared to baseline values. Notably, the two recipients with early graft failures, and their related LDs, regained their mental well-being during the first years after graft failure and remained stable after 5 years. LIMITATIONS, REASONS FOR CAUTION: The restricted sample size and the single-centre study-design are limitations of this study. Additionally the study was limited to LD UTx, as opposed to deceased donor UTx. WIDER IMPLICATIONS OF THE FINDINGS: Our study shows that both LDs and recipients had acceptable or favourable quality-of-life outcomes, including mood assessment, at the 5-year follow-up mark, and that failure to achieve a live birth negatively affected these modalities both for LDs and recipients. Moreover, an important finding was that LDs and recipients are not reacting with depression after hysterectomy, which is common after hysterectomy in the general population. STUDY FUNDING/COMPETING INTEREST(S): Funding was provided by the Jane and Dan Olsson Foundation for Science, Knut and Alice Wallenberg Foundation, Handlanden Hjalmar Svensson Foundation, Swedish Governmental ALF Grant, and Swedish Research Council. There are no conflicts of interest to disclose. TRIAL REGISTRATION NUMBER: NCT01844362.

Comparison of perioperative surgical outcomes between contained and free manual vaginal morcellation of large uteruses following total laparoscopic hysterectomy.

OBJECTIVE: To compare contained and free manual vaginal morcellation of large uteruses after total laparoscopic hysterectomy (TLH) in women at low risk of uterine malignancy in terms of feasibility and safety. METHODS: A single-center, observational, retrospective, cohort study was carried out including all patients undergoing TLH requiring manual vaginal morcellation for specimen extraction of large uteruses from January 2015 to August 2021 at the Division of Gynecology and Human Reproduction Physiopathology, IRCCS Azienda Ospedaliero-Universitaria of Bologna, Bologna, Italy. Patients were divided into two groups according to the type of manual vaginal morcellation (contained or free), and compared in terms of demographic, clinical, and perioperative data. RESULTS: In all, 271 patients were included: 186 (68.6%) in the contained morcellation group and 85 (31.4%) in the free morcellation group. The mean operative time was significantly lower in the contained morcellation group compared with the free morcellation group (median [interquartile range] 130 [45] vs. 155 [60] min; P < 0.001). No significant difference was found in complications related to the morcellation step, overall, intraoperative and postoperative complications, estimated blood loss, length of hospital stays, uterine weight, and rate of occult malignancy between the two groups. CONCLUSION: Contained vaginal manual morcellation of the uterus after total laparoscopic hysterectomy using a specimen retrieval bag appears to be a safe procedure with significantly lower operative time than free vaginal manual morcellation.

A Case Report of Familial Mayer-Rokitansky-Küster-Hauser Syndrome as Part of the Phenotypic Spectrum of the 2q37 Deletion.

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.

Fertility, pregnancy and perioperative outcomes after operative hysteroscopy for uterine septum: a network meta-analysis.

INTRODUCTION: Septate uterus is a congenital malformation associated with adverse reproductive and pregnancy outcomes. It remains controversial whether hysteroscopic septoplasty should be recommended for the treatment of septate uterus, and it is also unclear if different hysteroscopic methods have more favorable outcomes. This study aims to compare the available hysteroscopic techniques of septoplasty for fertility, reproductive, and perioperative outcomes. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. We searched Medline, Scopus, and Cochrane databases up to April 2023 without language restrictions. Eligible studies had to compare two or more different methods of hysteroscopic septoplasty in women with septate uterus and report on fertility and pregnancy outcomes after a follow-up. Perioperative outcomes were also examined. Data extraction was performed by two independent reviewers using a standardized form. Risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Form and Revised Cochrane risk-of-bias tool (RoB 2). RESULTS: Out of 561 studies identified, 9 were included in the systematic review and meta-analysis. The comparison of different hysteroscopic septoplasty techniques based on the energy used showed higher pregnancy rates after mechanical septoplasty in comparison to electrosurgery, while miscarriage and live birth rates were comparable. Laser vs. electrosurgery and mechanical techniques of septoplasty had comparable pregnancy, miscarriage, and live birth rates. The network meta-analysis after comparing every different method used showed significantly higher clinical pregnancy rate in scissor group in comparison to resectoscope. No significant differences were found among the techniques regarding miscarriage rate and live birth rate. CONCLUSION: In summary, this systematic review and network meta-analysis suggests that hysteroscopic septoplasty with scissors is associated with higher pregnancy rates compared to resectoscope. However, the limited evidence available and small sample sizes in the included studies indicate that these findings should be interpreted with caution. Further studies are required to determine the effectiveness of various hysteroscopic techniques and guide clinical decision-making in the management of this condition.

Comparison of clinical outcomes and second-look hysteroscopy of the complete and incomplete septate uterus after hysteroscopic septoplasty.

PURPOSE: Septate uterus is the most common congenital uterine malformation. This retrospective cohort study compared clinical outcomes and second-look hysteroscopy findings in patients with complete and incomplete septate uteri after septoplasty. METHODS: We reviewed the medical records of patients with a septate uterus who underwent hysteroscopic septoplasty and second-look hysteroscopy at the West China Second University Hospital between September 2013 and September 2021. Information regarding pregnancy outcomes was collected through telephone interviews. The independent samples t-test, Mann-Whitney U test, Pearson's chi-square test, and Fisher's exact test were used to explore the differences between the complete and incomplete septate uterus groups. RESULTS: A total of 64 patients were enrolled in this study. There was no significant difference in intrauterine adhesion (IUA) rates (16.7% and 32.1%), pregnancy rates (44.1% and 42.9%), term delivery rates (35.3% and 32.1%), premature delivery rates (2.9% and 0), placenta previa rates (2.9% and 3.6%), placenta implantation/adhesion rates (5.9% and 3.6%), and premature rupture of membranes rates (2.9% and 0) between the complete and the incomplete group after hysteroscopic septoplasty (P > 0.05). Endometrial polyps in the septate uterus were common, with an incidence of 33.3% and 25% in the complete and incomplete groups, respectively (P > 0.05). CONCLUSION: The pregnancy outcomes of complete and incomplete septate uteri after hysteroscopic septoplasty were similar. There was no statistical difference in IUAs after surgery. Different treatment strategies may not be required for complete or incomplete septate uteri.

Presentation and Management of Uterine Didelphys with Unilateral Cervicovaginal Agenesis/Dysgenesis (CVAD): A Multicenter Case Series.

INTRODUCTION: There are several well-described presentations of uterine didelphys (UD): UD without vaginal septum, UD with non-obstructed longitudinal vaginal septum, or UD with duplicated vaginas and an obstructed hemivagina on one side with ipsilateral renal anomaly. STUDY OBJECTIVE: To describe another variant of UD and compare the presentation and management across different institutions METHODS: This was a retrospective case series approved by the NASPAG Fellows Research Consortium. Participating institutions obtained IRB approval. Inclusion criteria included a diagnosis of UD and unilateral cervicovaginal agenesis/dysgenesis (CVAD). Descriptive statistics were used. RESULTS: Five patients met the inclusion criteria, with ages ranging from 13 to 27 years. Presenting symptoms included dysmenorrhea (80%), irregular bleeding (40%), acute onset left lower quadrant pain (20%), and abdominal mass (20%). Three patients had additional known abnormalities, including solitary kidney and solitary adrenal gland. All patients underwent pelvic magnetic resonance imaging. Two cases were only suspicious for unilateral CVAD on imaging and required pathology review postoperatively to confirm diagnosis. Two cases required a 2-staged approach with an initial diagnostic surgery followed by a second definitive procedure. Three patients were noted to have endometriosis intraoperatively. Postoperative follow-up ranged from 2 months to 2 years, with 1 patient reporting chronic pelvic pain. CONCLUSION: Diagnosis on the basis of pelvic imaging can be difficult, as this unique variant may mimic classic obstructed hemivagina with ipsilateral renal anomaly. In patients with UD with unilateral CVAD, standard management is removal of the obstructed uterine horn. This multicenter series stresses awareness about the clinical presentation, distinguishes cases of cervical agenesis from dysgenesis, and reviews approaches to management.

Obstructed Hemivagina and Renal Anomalies in Patients with and without Anorectal Malformations.

STUDY OBJECTIVE: To compare the anatomic variation between patients with a diagnosis of an obstructed hemivagina with an anorectal malformation (ARM) and those without an ARM. METHODS: This was a retrospective chart review conducted at a single tertiary children's hospital. Patients with an obstructed hemivagina seen from 2004 to 2019 were included. RESULTS: We identified a total of 9 patients diagnosed with an obstructed hemivagina: 4 patients with a history of ARM and 5 patients without an ARM. Patients presented with obstructive symptoms between the ages of 11 and 20. Two-thirds of patients had a left-sided obstruction. All patients without an ARM had ipsilateral congenital anomalies of the kidney and urinary tract. Half the patients with a history of ARM had an ipsilateral renal anomaly, and the other half had a contralateral renal anomaly. CONCLUSION: Obstructed hemivagina occurs in patients with a history of ARM. However, unlike patients with isolated obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), patients with an ARM and an obstructed hemivagina can present with associated renal anomalies on either the ipsilateral or contralateral side. In our small case series, patients with a history of ARM had high septa and required more complex surgical management due to the inability to access the septum vaginally. Knowledge of renal anatomy and ureteral path is important because a hysterectomy may be needed to relieve the obstruction in patients with ARMs. A larger case series is needed to better characterize the spectrum of complex anomalies in patients with ARMs.

Unilateral segmental uterine horn hypoplasia with fallopian tube aplasia in a guinea pig (Caviaporcellus).

A 2-year-3-month-old female guinea pig (Cavia porcellus) was referred for lethargy, weight gain and severe abdominal pain. Ultrasound examination revealed thickening and enlargement of the left uterine horn and an unremarkable right uterine horn. The animal died during ovariohysterectomy due to respiratory and cardiac arrest. Necropsy revealed unilateral segmental uterine horn hypoplasia and aplasia of the fallopian tube of the corresponding side. This is the first report of a congenital uterine malformation in the guinea pig and we describe the clinical and pathological presentation of segmental uterine horn hypoplasia and fallopian tube aplasia. Congenital uterine malformations are rare in guinea pigs but should be considered as differential diagnoses for the more common acquired uteropathies.
