Congenital malformations of the uterus are rare. Pregnancies in these uterine abnormalities are usually associated with poor reproductive outcomes such as recurrent pregnancy losses, preterm birth and intrauterine growth restriction. Presented here is the case of a 21-year old G2P1(1001), who was diagnosed intraoperatively with a septate bicornuate uterus during her second Cesarean delivery. She had to undergo abdominal delivery for both her pregnancies due to malpresentation, and delivered live healthy babies with no gross structural defects. Pathophysiology and classification of congenital uterine malformations are discussed in the case, as well as the diagnostics and management for such conditions.

OBJECTIVES: To investigate the association between insulin resistance and uterine volume in girls with idiopathic central precocious puberty (ICPP). METHODS: A retrospective study was conducted involving 61 girls diagnosed with ICPP who visited the pediatric growth and development clinic of the Third Affiliated Hospital of Zhengzhou University between January 2022 and September 2024, designated as the ICPP group, and 61 normally developing girls as the control group. The differences in insulin resistance index (homeostasis model assessment of insulin resistance, HOMA-IR), uterine volume, and other indicators between the two groups were compared, and the relationship between insulin resistance and uterine volume in these girls was analyzed. RESULTS: The uterine volume and HOMA-IR level in the ICPP group were significantly higher than those in the control group (P<0.05). Correlation analysis revealed that there was a positive correlation between HOMA-IR level and uterine volume in the ICPP group (r_s=0.643, P<0.001). Multiple linear regression analysis indicated that as HOMA-IR increased,uterine volume in the girls tended to increase (P<0.05). CONCLUSIONS There is an association between insulin resistance and uterine volume in girls with ICPP, and as HOMA-IR increases, uterine volume in the girls also increases.

Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

OBJECTIVES: Pelvic organ prolapse (POP) is a common condition in postmenopausal women, with an increasing prevalence due to aging. Some women experience POP recurrence after surgical treatment, significantly affecting their physical and mental health. The uterosacral ligament is a critical pelvic support structure. This study aims to investigate the molecular pathological changes in the uterosacral ligament of postmenopausal women with recurrent POP using transcriptomic analysis. METHODS: Transcriptomic data of uterosacral ligament tissues were obtained from the public dataset GSE28660, which includes samples from 4 postmenopausal women with recurrent POP, 4 with primary POP, and 4 without POP. Differentially expressed genes (DEGs) were identified between recurrent POP and both primary and non-POP groups. Further analysis included intersection analysis of DEGs, gene ontology enrichment, protein-protein interaction (PPI) network construction, gene set enrichment analysis (GSEA), single-sample GSEA, and xCell immune cell infiltration analysis to explore molecular pathological changes in recurrent POP. Additionally, histological and molecular differences in the uterosacral ligament were compared between simulated vaginal delivery (SVD) rat models with and without ovariectomy. RESULTS: Compared with primary POP and non-POP groups, recurrent POP exhibited activation of adipogenesis and inflammation-related pathways, while pathways related to muscle proliferation and contraction were downregulated in the uterosacral ligament. Nine key DEGs (ADIPOQ, FABP4, IL-6, LIPE, LPL, PCK1, PLIN1, PPARG, and CD36) were identified, with most enriched in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. These genes were significantly correlated with lipid accumulation, monocyte infiltration, and neutrophil infiltration in the uterosacral ligament. Urodynamic testing revealed that the bladder leak point pressure was significantly higher in ovariectomized SVD rats, both of which had higher values than the sham group. Masson staining showed pronounced adipogenesis in the uterosacral ligament of ovariectomized SVD rats, along with reduced collagen and muscle fibers compared to the sham and non-ovariectomized SVD groups. Furthermore, real-time RT-PCR confirmed significantly elevated expression of key DEGs, including ADIPOQ, IL-6, PCK1, and PLIN1, in the uterosacral ligaments of ovariectomized SVD rats. CONCLUSIONS Adipogenesis and inflammation in the uterosacral ligament may contribute to its reduced supportive function, potentially leading to recurrence POP in postmenopausal women.

Independent primary uterine and cervical adenocarcinoma are rare and difficult to identify their origins, which makes treatment decision difficult. A 46-year-old female with endometrioid carcinoma and adenocarcinoma, human papilloma virus (HPV)-associated of the uterine cervix was reported. The patient presented with increased menstrual flow, contact bleeding and watery leucorrhea for more than one year, and the imaging findings showed abnormal uterine morphology, irregular margins, and multiple abnormal signals in uterine cavity and myometrium, which suggested multiple leiomyomas of the uterus. The signal intensity in the right muscle layer was markedly enhanced, suggesting a smooth muscle tumor of uncertain malignant potential. A large number of cystic hypointensity was seen in the cervix, and multiple cysts were considered. The initial preoperative diagnosis was multiple leiomyoma of the uterus, and a hysterectomy operation was planned. During the operation, the uterus was sent for frozen sections. There was a mass in the endometrium of the fundus, with a soft grayish-red cut surface and a clear border with the myometrium, and there was a grayish-white nodule in the cervix with a hard grayish-white cut surface. The two masses were well demarcated from each other, and the distance between them was 30 mm. The result of the frozen sections indicated the malignant tumor of the endometrium, and the extended hysterectomy+pelvic lymphadenectomy+partial resection of the greater omentum was performed. After the operation, the paraffin sections were sent to the Department of Pathology of the Peking University Third Hospital for histochemistry, POLE gene sequencing and HPV RNAscope tests, and the final diagnosis was a synchronous endometrioid carcinoma (POLE-mutant according to the WHO classification) and an adenocarcinoma, HPV-associated of the uterine cervix. Now the patient had been treated with 2 cycles of chemotherapy and her condition was fine. Through the analysis of the histological, immunohistochemical and molecular detection results of this case, the importance of applying HPV RNAscope and TCGA molecular typing in the diagnosis of cervical adenocarcinomas and endometrial carcinomas was emphasized. At the same time, gynecologists should not blindly rely on intraoperative frozen sections, and should pay attention to preoperative pathological examination, and make appropriate operation methods according to the results in order to prevent passivity in the surgery.

OBJECTIVES: Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare female genital tract malformation, and there are few large sample studies reported at home and abroad. The clinical manifestations of this syndrome are diverse, and insufficient understanding may delay the diagnosis and treatment of the patients. This study aims to analyze the clinical characteristics of different types of HWWS patients, and to improve the diagnosis and treatment of HWWS. METHODS: The clinical data of patients with HWWS who were hospitalized in the Department of Obstetrics and Gynecology, Third Xiangya Hospital of Central South University from October 1, 2009 to April 5, 2022 were retrospectively analyzed. The age, medical history, physical examination, imaging examination and treatment of the patients were collected for statistical analysis. The patients were divided into an imperforate oblique vaginal septum type, a perforate oblique vaginal septum type, and an imperforate oblique vaginal septum and cervical fistula type. The clinical characteristics of different types of HWWS patients were compared. RESULTS: A total of 102 HWWS patients were enrolled, with age of 10-46 years old, including 37 (36.27%) patients with type I, 50 (49.02%) type II, and 15 (14.71%) type III. All patients were diagnosed after menarche, with an average age of (20.5±7.4) years. There were significant differences in the age of diagnosis and course of disease among the 3 types of HWWS patients (both P<0.05). Patients with type I had the youngest age of diagnosis [(18.0±6.0) years] and the shortest course of disease (median course of 6 months), while patients with type III had the oldest age of diagnosis [(22.9±9.8) years] and the longest course of disease (median course of 48 months). The main clinical manifestation of type I was dysmenorrhea, and the main clinical manifestation of type II and type III was abnormal vaginal bleeding. Of the 102 patients, 67 (65.69%) patients had double uterus, 33 (32.35%) had septate uterus, and 2 (1.96%) had bicornuate uterus. The vast majority of patients had renal agenesis on the oblique septum, and only 1 patient had renal dysplasia on the oblique septum. The oblique septum located on the left side in 45 (44.12%) patients and on the right side in 57 (55.88%) patients. There were no significant differences in uterine morphology, urinary system malformation, pelvic mass, and oblique septum among the 3 types of HWWS patients (all P>0.05). Six (5.88%) patients had ovarian chocolate cyst, 4 (3.92%) patients had pelvic abscess, and 5 (4.90%) patients had hydrosalpinx. All patients underwent vaginal oblique septum resection. Among them, 42 patients underwent hysteroscopic incision of the oblique vaginal septum without destroying the intact hymen because they had no sexual life history, and the remaining 60 patients underwent traditional oblique vaginal septum resection. Among the 102 patients, 89 patients were followed up for 1 month to 12 years. The symptoms of vaginal oblique septum in 89 patients such as dysmenorrhea, abnormal vaginal bleeding and vaginal discharge were improved after operation. Among the 42 patients who underwent hysteroscopic incision of the oblique vaginal septum without destroying the intact hymen, 25 patients underwent hysteroscopies again 3 months after operation, and there was no obvious scar formation at the oblique septum incision site. CONCLUSIONS Different types of HWWS have different clinical manifestations, but all can be manifested as dysmenorrhea. The patient's uterine morphology can be manifested as double uterus, septate uterus, or bicornuate uterus. The possibility of HWWS should be considered if uterine malformation is combined with renal agenesis. Vaginal oblique septum resection is an effective treatment.

Objective: To investigate the value of uterine morphological parameters and endometrial T₂ signal intensity (T₂-SI) in evaluating the degree of the fibrotic repair secondary to endometrial injury. Methods: From Sep. 2018 to Feb. 2023, this study prospectively enrolled 29 patients with fibrotic repair secondary to severe endometrial injury (severe group), 17 patients with fibrotic repair secondary to mild to moderate endometrial injury (mild to moderate group), and 40 healthy women of reproductive age (control group) in Nanjing Drum Tower Hospital. The length of uterine cavity (LUC), length of cervix and isthmus (LCI), width of upper uterine cavity (WUUC) and width of lower uterine cavity (WLUC) were measured using magnetic resonance imaging. T₂-SI of endometrium and subcutaneous fat of buttocks were measured, and endometrial normalized T₂-SI (nT₂-SI; T₂-SI of endometrium/T₂-SI of subcutaneous fat of buttocks) was calculated. Statistical analyses of data were performed using one-way analysis of variance, Mann-Whitney U test, intraclass correlation coefficient, Spearman rho test, area under the receiver operating characteristic curve (AUC). Results: LUC, WUUC, WLUC and endometrial nT₂-SI of severe group [(19.7±3.5) mm, (26.9±6.4) mm, (7.9±1.4) mm, 0.73±0.11, respectively] were significantly lower than those of the control group (all P<0.01), while LCI and WUUC/LUC [(51.3±7.3) mm and 1.38±0.34] were significantly higher than those of the control group (all P<0.001). LUC and WLUC of severe group were significantly lower than those of mild to moderate group [(32.4±5.1) mm and (8.8±1.2) mm; all P<0.05], while LCI and WUUC/LUC were significantly higher than those of mild to moderate group [(41.8±8.6) mm and 0.94±0.16; all P<0.001]. LUC and endometrial nT₂-SI of mild to moderate group were significantly lower than those of the control group [ (32.4±5.1) vs (35.3±3.5) mm, 0.68±0.13 vs 0.80±0.12; all P<0.01]. LUC, WUUC, WLUC and endometrial nT₂-SI were significantly negatively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho:-0.794, -0.441, -0.471 and -0.316, respectively; all P<0.05), while LCI and WUUC/LUC were significantly positively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho: 0.481 and 0.674, respectively; all P<0.05). LUC and WUUC/LUC showed high value in distinguishing severe group from the control group or mild to moderate group (all AUC>0.9, all P<0.001). Conclusion: As noninvasive and quantitative biomarkers, uterine morphological parameters and endometrial nT₂-SI could evaluate the degree of the fibrotic repair secondary to endometrial injury.

Intrauterine device(IUD)migrating to the bladder is rare,especially the migration far away from the uterus into the bladder wall.Due to no obvious clinical symptom in the early stage and being far away from the uterus,the IUD totally embedded in the bladder wall is prone to misdiagnosis and delay in treatment.We reported one case of such migration,aiming to improve the clinical management of the IUD totally embedded in the bladder wall.
