OBJECTIVE: To assess the influence of advanced maternal age on congenital malformations, and short- and long-term outcomes in offspring of nulligravida. METHODS: A retrospective study was conducted using the Korean National Health Insurance Service database spanning from January 2005 to December 2019. All live-born offspring of nulligravida (n=3,685,817) were included. The maternal age was subdivided into the following subgroups: <25 years (n=153,818), 25-29 years (n=845,355), 30-34 years (n=1,738,299), 35-39 years (n=787,530), 40-44 years (n=151,519), and >44 years (n=9,296)...

In an 8-year period at two medical center, 138 patients underwent uterine artery embolization, and 11 of them were diagnosed with uterine necrosis. Among them, three were successfully conceived. However, one of them developed an arteriovenous malformation after an artificial abortion, and another experienced complications, including placenta previa and placenta accreta spectrum, which resulted in early preterm delivery and recurrent postpartum hemorrhage, necessitating subtotal hysterectomy. Therefore, it is crucial to prepare for potential adverse pregnancy outcomes in subsequent pregnancies for patients with a history of uterine necrosis...

Cervical cancer continues to pose a challenge to the health of Thai women, as the second most common cancer after breast cancer. Since high risk human papillomavirus (HPV) type is the main cause for cervical cancer, cervical cancer screening and HPV vaccination is necessary to reduce the incidence of this disease. At present, the World Health Organization hopes to reduce the incidence of cervical cancer to 4 or less cases per 100,000 women per year using 90-70-90% intervention by 2030. The first intervention involves vaccinating 90% of women aged 15 years with the HPV vaccine...

OBJECTIVE: We aimed to predict the risk posed by postoperative adjuvant therapy using preoperative variables in young patients with early stage cervical cancer. The predicted risk can guide whether ovarian transposition should be performed during surgery. METHODS: This multicenter retrospective study was conducted using data from the Korean Gynecologic Oncology Group (KGOG) 1028 study. In total, 886 patients with stage IB1-IIA cervical cancer aged 20-45 years who underwent modified radical or radical hysterectomy between January 2000 and December 2008 were included...

OBJECTIVE: Stress urinary incontinence (SUI) is a common problem that affects the quality of life of women worldwide. Pelvic floor muscle training (PFMT) is an effective conservative first-line treatment for SUI. However, low compliance with PFMT is one of the main reasons for therapeutic failure. Indirect supervision using a guidebook may improve PFMT outcomes. To develop a PFMT guidebook using the analyze, design, development, implementation, and evaluation (ADDIE) method. METHODS: A guidebook was developed from July 2020 to April 2021 using the ADDIE method...

OBJECTIVE: This study aimed to describe the clinical features, associated extragenital anomalies, and management of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome in a Thai population. METHODS: This retrospective study analyzed the medical records of 96 patients with MRKH syndrome diagnosed and treated at a university hospital and tertiary referral center in southern Thailand between 2000 and 2022. RESULTS: The study included 96 patients with MRKH syndrome...

OBJECTIVE: To compare attitudes toward self-sampling for human papillomavirus (HPV) testing before and after specimen collection in women undergoing colposcopy. The factors associated with the pre-sampling attitude were also studied. METHODS: This prospective study enrolled women with abnormal cervical cytology and/or positive high-risk HPV who attended colposcopy clinics at 10 cancer centers in Thailand between October 2021 and May 2022. Prior to colposcopy, the attitudes of the women toward self-sampling were surveyed through a questionnaire...

OBJECTIVE: To assess the utility of ultrasound and color Doppler and the Accuracy of International Ovarian Tumor Analysis (IOTA) group classification in the preoperative evaluation of ovarian neoplasms to assess benign or malignant histopathology in the diagnosis of ovarian tumors. METHODS: This observational longitudinal prospective analysis of 60 patients was performed over a period of 2 years (2017- 2019). The mean age of the patients was 43.75 years. Ultrasonography of ovarian masses were evaluated, and cancer antigen-125 (CA-125) levels were evaluated...

OBJECTIVE: Controlled ovarian stimulation leads to profound changes in the endocrine characteristics of the ovarian cycle. Serum luteinising hormone (LH) levels on the day of trigger have been shown to correlate with oocyte quality and pregnancy rate in antagonist cycles. METHODS: This is an observational study of 86 women undergoing an antagonist in-vitro fertilisation cycle. Oocyte maturation trigger used was either Inj. human chorionic gonadotropin or Inj. triptorelin 0...

Vulvar intraepithelial neoplasia (VIN) is a noninvasive squamous lesion that is a precursor of vulvar squamous cell cancer. Currently, no screening tests are available for detecting VIN, and a biopsy is performed to confirm the clinical diagnosis. Despite sharing many risk factors with cervical intraepithelial neoplasia, the diagnosis of VIN is poses challenges, contributing to its increasing prevalence. This study aimed to analyze the underlying risk factors that contribute to the development of VIN, identify specific populations at risk, and define appropriate treatment approaches...

Pelvic organ prolapse (POP) is a common cause of gynecological disease in elderly women. The prevalence of POP has increased with an aging society. Abdominal sacrocolpopexy (ASC) is safer and more effective than the vaginal approach in patients with apical compartment POP because it has a higher anatomical cure rate, a lower recurrence rate, less dyspareunia, and improved sexual function. Laparoscopic sacrocolpopexy (LSC) has replaced ASC. Robotic sacrocolpopexy (RSC) also helps overcome the challenges of LSC by facilitating deep pelvic dissection and multiple intracorporeal suturing...

Proper placentation during early pregnancy is a key factor for maintaining a healthy pregnancy. Placental insufficiency leads to critical complications such as preeclampsia, fetal growth restriction, and fetal demise. These complications are often associated with pathological findings of restricted remodeling and obstructive lesions of the myometrial spiral arteries, which have high recurrence rates during subsequent pregnancies. Currently, there are no pharmacological interventions other than aspirin for the prevention of preeclampsia...

This study reviews the progress and recent advances in vaginal natural orifice transluminal endoscopic surgery (vNOTES) as a minimally invasive gynecologic procedure. The proposed advantages of vaginal natural orifice transluminal surgery include enhanced cosmesis due to a scarless procedure, better exposure compared with the pure vaginal approach, tolerable pain scores, fewer perioperative complications, and a shorter hospital stay. Recent advances in surgical instrumentation and technology have improved the feasibility of vNOTES as an innovative treatment option for gynecological conditions...

OBJECTIVE: Adenomyosis impacts pregnancy outcomes, although there is a lack of consensus regarding the actual effects. It is likely, however, that the severity of adenomyosis or ultrasound findings or timing of diagnosis can have different effects on adverse pregnancy outcomes (APOs). METHODS: In this study, we aimed to investigate the impact of the timing of adenomyosis diagnosis on pregnancy outcomes. Singleton pregnant women who delivered between 2017 and 2022 were analyzed based on the timing of adenomyosis diagnosis, using a national database...
