Abstract
A T-shaped uterus is a rare uterine malformation that is classically associated with diethylstilbesterol (DES) exposure. Surprisingly, the prevalence of T- and Y-shaped uterus has increased in recent years despite the absence of a diagnostic consensus and a correlation with the reproductive outcomes has been observed. A systematic electronic database search for all English-language studies published on reproductive outcomes associated with dysmorphic uteri over the past 10 years using PubMed, Google Scholar, and Scopus was performed. This uterine malformation is associated with impaired reproductive outcomes, including primary infertility, miscarriage, ectopic pregnancy, and preterm birth. Hysteroscopic metroplasty is a simple surgical procedure that could potentially improve outcomes in subfertile women, but the data are not robust. Studies reported significant improvements in implantation and pregnancy rates after corrective metroplasty in women undergoing in vitro fertilization. However, multicenter, prospective, randomized, and controlled trials are needed to validate these findings and to help define clear diagnostic criteria, surgical indications, and appropriate follow-up of reproductive outcomes after the procedure.

Arch Gynecol Obstet 2024:10.1007/s00404-024-07642-8. [PMID: 39008085 DOI: 10.1007/s00404-024-07642-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Accepted: 07/07/2024] [Indexed: 07/16/2024]
Abstract
PURPOSE The eccentric implantation of pregnancies in the upper lateral aspect of the uterine cavity is poorly defined clinically. The aim of the current study was to investigate whether differentiating between uterine anomalies that can lead to cavitary distortion has implications for the management of these pregnancies. METHODS Eight cases of first-trimester eccentric pregnancy implantation within the endometrial cavity (study group) were retrospectively identified. For each woman in the study group, 10 women identified as having a first-trimester concentric pregnancy implantation during the first-trimester US examination were retrieved from our database (control group). After delivery or pregnancy demise, the presence of uterine anomalies was assessed by a 3D-US examination in all patients. RESULTS In the study group patients, an increased incidence of uterine anomalies (50.0% vs. 8.8%, p = 0.007) was found, compared to the controls. In the study group, the eccentric location persisted in half of the pregnancies (n = 4; 50%), whereas the other half migrated to a more centric location within the endometrial cavity (n = 4; 50%). The follow-up examination showed that all the early pregnancy demises occurred in cases where the pregnancy persisted at the eccentric location. Uterine malformations were also detected in all these cases. CONCLUSION The data point to a significantly higher incidence of uterine anomalies in patients diagnosed with eccentric pregnancy implantation within the endometrial cavity. These results advocate for the value of differentiating between eccentric pregnancies in non-anomalous versus anomalous uteri.

Abstract
STUDY OBJECTIVE To define objective and readily applied diagnostic criteria for Y-shaped uteri using 3-dimensional transvaginal ultrasound (3D-TVUS) volume recordings. DESIGN A retrospective case-control diagnostic measurements study. SETTING A tertiary university hospital's reproductive health and research center. PATIENTS Two hundred thirteen patients who presented with infertility between January 2020 and December 2022. INTERVENTIONS Two blinded physicians re-evaluated the 3D-TVUS images of all patients for the presence of a uterine abnormality. The images of patients with a Y-shaped uterus were re-evaluated, and descriptive measurements were done. MEASUREMENTS AND MAIN RESULTS The most common uterine abnormality in this cohort was the Y-shaped uterus with a prevalence of 12.2%, followed by the arcuate, T-shaped, and septate uteri, respectively. Reviewers identified 26 and 28 Y-shaped uteri, respectively, and came to a consensus on 25 images. Diagnostic criteria for the Y-shaped uterus based on 3D-TVUS findings have been specified as: lateral indentation depths between 4 and 7 mm, fundal indentation depth between 5 and 9 mm, lateral indentation angles between 121° and 149°, fundal indentation angle between 121° and 145°, and Y-angles 25° to 46°. CONCLUSION Some subtypes of dysmorphic uteri, such as the Y-shaped uterus, whose clinical significance is unknown and may be variants of the normal, may actually be more common than thought. Determining objective diagnostic criteria with 3D-TVUS will allow standard research on these anomalies and their clinical significance.

Abstract
BACKGROUND Robert's uterus is a rare congenital anomaly, characterized as an asymmetric septate uterus that has a blind hemicavity with unilateral menstrual fluid retention and a unicornuate hemicavity connecting to the cervix unimpededly. Patients with Robert's uterus generally present with menstrual disorders and dysmenorrhea, and some may have reproductive problems as well, including infertility, recurrent miscarriage, preterm labor and obstetric complications. In this case, we describe a successful pregnancy implanted on the obstructed hemicavity and delivered a liveborn girl. Meanwhile, we highlight diagnostic and therapeutic difficulties in patients with atypical symptoms of Robert's uterus. CASE PRESENTATION A 30-year-old Chinese primigravida sought for emergency treatment at 26 weeks and 2 days of gestation because of preterm premature rupture of membranes (PPROM). At the age of 19, the patient was misdiagnosed with hyperprolactinemia and pituitary microadenoma for showing symptom of hypomenorrhea and was suspected to have a uterine septum in the first trimester. She was diagnosed with Robert's uterus at 22 weeks of gestation by repetitious prenatal transvaginal ultrasonography, which was subsequently confirmed by magnetic resonance imaging. At 26 weeks and 3 days of gestation, the patient was suspected to have oligohydramnion, irregular uterine contraction, and umbilical cord prolapse, and she expressed a strong will of saving the baby. Emergency cesarean delivery was performed and a small hole, together with several weak spots, was found at the lower and back wall of the septum of the patient. The treatment was effective and both the mother and the infant, who had an extremely low birth weight, were discharged in good health conditions. CONCLUSIONS Pregnancy in the blind cavity of Robert's uterus with living neonates is incredibly rare. In our case, the favorable outcome may result from the unusual hole found at the septum, which may play a role in communicating amniotic fluid between the two hemicavities so to keep the neonate alive. we highlight the importance of early diagnosis and pre-pregnancy treatment of this uterine malformation, and the timely termination of pregnancy, for improving birth quality and reducing mortality.

Abstract
OBJECTIVE T/Y-shaped dysmorphic uterus is frequently associated with subfertility, abortion, preterm delivery, and recurrent implantation failure. In this study, the impact of hysteroscopic metroplasty for a T/Y-shaped uterus on obstetric outcomes was investigated in patients with infertility and recurrent pregnancy loss (RPL) and compared the uterine anomaly subgroups. METHOD Cases with infertility and/or RPL diagnosed with T/Y-shaped uterus by hysterosalpingography (HSG) and 3D transvaginal ultrasonography (3D TVUSG) with no other male or female pathology have recruited the study. Medical history and the obstetric outcome after two years of follow-up were recorded. RESULTS Out of the 92 cases recruited, T-shaped uteri (Group-1) were observed in 30, while 62 (67.3%) patients had Y-shaped uteri. Pregnancy was achieved in 50 (54.3%) of the cases, 28 (56%) of the pregnancies occurred spontaneously, and in 22 (44%) pregnancy was achieved through assisted reproductive techniques (ART). Term delivery occurred in 29 (76.3%) of the pregnancies while 9 (23.6%) had preterm deliveries and a total of 38 (76%) resulted in a live birth. Out of the 31 patients with previous RPL history, 13 (41.9%) achieved pregnancy and 11 out of 13 (84.6%) had a term pregnancy followed by live birth. CONCLUSION Spontaneous pregnancy, and term pregnancy rates after surgery were found to be promising in these uterine anomalies. The pregnancy outcome of the primary infertile patients was found the same in two groups (50%-46.1%), but the results of the RPL patients were found to be better in the T-shaped group than in the Y-shaped group (70%-28.5%).

Abstract
PURPOSE To investigate and propose a new simple tridimensional (3D) ultrasonographic method to diagnose a T-shaped uterus (Class U1a). METHODS A multicenter non-experimental case-control diagnostic accuracy study was conducted between January 2018 and December 2019, including 50 women (cases) diagnosed with T-shaped uterus (U1a class) and 50 women with a "normal uterus" (controls). All the enrolled women underwent 3D ultrasound, drawing four lines and recording the length of three of them as follow: draw and measure the interostial line (R0); draw from the midpoint of R0 a perpendicular line length 20 mm; draw and measure in the uterine cavity a line parallel to R0 at 10 mm below R0 (R10) and a second line parallel to R0 at 20 mm below R0 (R20). The diagnostic performance of all sonographic parameters statistically significantly different between T-shaped and normal uteri was estimated using the receiver operator characteristic (ROC) curve analysis. RESULTS R10 and R20 were statistically significantly shorter in the T-shaped than the normal uterus. R10 reported the highest diagnostic accuracy with an area under the ROC curve of 0.973 (95% CI 0.940-1.000). R10 length maximizing the Youden's J statistic was 10.5 mm. Assuming R10 length equal to or shorter than 10 mm as the cut off value for defining a woman as having a T-shaped uterus, the new ultrasonographic method following the proposed protocol (R0, R10, and R20) reported sensitivity for T-shaped uterus of 91.1% (95% CI 0.78-0.97%) and a specificity of 100% (95% CI 0.89-100%). The positive likelihood ratio was higher than 30, and the negative likelihood ratio was 0.09 (95% CI 0.04-0.26). CONCLUSIONS Measuring the length of the intracavitary line parallel to the interostial line at 10 mm from it and using a length ≤ of 10 mm as cut off value (the "Rule of 10") appears a simple and accurate 3D ultrasonographic method for the diagnosis of a T-shaped uterus.

Abstract
This paper aims to study the efficacy and safety of diode laser hysteroscopic metroplasty for dysmorphic uterus and the impact on reproductive outcomes. This is a retrospective, single-center pilot study with prospective follow-up. The study was performed at a university-affiliated, tertiary hospital. From February 2018 to February 2020, all nulliparous women with a 3D ultrasound diagnosis of T-shaped or Y-shaped dysmorphic uterus and diagnosis of infertility, recurrent implantation failure, or recurrent pregnancy losses were referred for hysteroscopic metroplasty. Diode laser hysteroscopic metroplasty was performed under general anesthesia in an ambulatory setting. Main outcome measures included operative time, complications, hysteroscopic appearance of the cavity in a follow-up hysteroscopy, and reproductive outcomes in terms of pregnancy and live birth. A total of 25 infertile women with mean duration of infertility of 56.6 ± 36.1 months underwent hysteroscopic metroplasty. No complications were reported, and subsequent 3D ultrasound and follow-up hysteroscopic appearance were satisfactory in all cases. Maximum follow-up was 32 months (mean ± standard deviation 11.5 ± 9.2 months). Fifteen nulliparous women returned for fertility treatments in our institute, among whom nine conceived (60% pregnancy rate). The rate of deliveries and ongoing pregnancies (pregnancies beyond 24 weeks of gestation) was 78% (7/9), with six successful liveborn deliveries at 36-38 weeks and one ongoing pregnancy. One had spontaneous abortion at week 19 and one had a spontaneous abortion at week 7. Hysteroscopic metroplasty in an ambulatory setting, using diode laser, is a safe and effective procedure, improving reproductive outcomes in cases of T-shaped or Y-shaped uterus.
