Objective: To evaluate the newly formed epithelium that develops following a neovaginoplasty performed with Amniotic Membrane.
Methods: A retrospective study conducted at the University Hospital of the Federal University, in Curitiba, Paraná, Brazil. A group of 33 patients with Vaginal Agenesis, most of them amenorrhoeic, either incapable of or having difficulty to perform sexual activity, were separated in Subgroup A (27 patients) with Mayer-Rokitansky-Kuster-Hauser Syndrome, and Subgroup B (six patients) with Androgenic Insensitivity Syndrome (Morris Syndrome). Intervention: Banister-McIndoe neovaginoplasty was performed using amniotic membrane graft in 33 patients of Subgroups A and B and evaluated 60-90 days later by vaginal epithelium biopsies. Main Outcome Measure(s): Transmission Electronic Microscopy (TEM) performed Biopsies of neovaginal epithelium in 10 patients. In 20 patients, we analyzed the levels of intensity and presence of Estrogenic Receptors.
Results: Vaginal length was measured (vaginometry) before and after surgery. Before surgery, the vagina was absent in 5 patients (15.15%), vaginal length was 1 cm in 19 patients (57.58%) and in 9 patients (27.27%), it was between 2-3 cm. After surgery, all patients had a vaginal length greater or equal to 5 cm and, in 26 patients (78.8%), vaginal length was 7-8 cm. Seven to eight centimeters average neovagina length allowed patients to have a satisfactory sexual activity after all the surgical procedures to dilate, widen and distend the neomucosa lining. The ERs presented different levels of intensity in the three layers of the neovaginal mucosa. TEM analysis of the vaginal neoepithelium obtained from the amniotic membrane graft revealed all the characteristics of a trophic vaginal epithelium.
Conclusions: In a developing country like Brazil, neovaginoplasty with amniotic membrane graft is considered a great option, being an inexpensive, safe, and easy technique, not requiring any special materials. After a few days (60-90 days), or months, a new epithelium and vagina are obtained allowing patients to have proper sexual activity.

This study aimed to investigate the effect of cervical length on procedure time and VAS pain scores during office hysteroscopy. A cross-sectional study was conducted on 50 patients who underwent office hysteroscopy for various indications such as abnormal uterine bleeding and infertility. Exclusion criteria included active vaginal infection, previous cervical surgery, and chronic pelvic pain.

Importance: Women aged 90 years and older ("oldest-old") represent a small but growing population who may experience bothersome pelvic organ prolapse and opt for surgical repair.
Objective: This study aimed to compare perioperative adverse events (AEs) within 8 weeks of prolapse surgery between women ≥90 years and younger patients.
Study Design: We performed a secondary analysis of a dual-center retrospective cohort study of women ≥61 years old undergoing major prolapse surgery from January 2016 to May 2023.

From the Division of Urogynecology and Reconstructive Pelvic Surgery, Department of Obstetrics and Gynecology, University of Iowa Hospitals and Clinics, Iowa City, IA.
Importance: The Pelvic Organ Prolapse Quantification (POP-Q) stages do not correlate with symptoms or characterize important prolapse subtypes.
Objectives: We hypothesize that clinically meaningful prolapse "phenotypes" utilizing POP-Q measurements can be defined. The primary aim was to define the phenotypes and their frequency.
Describing Sacrocolpopexy in Medical Literature: A Proposed Surgical Classification System.

Western New York Urology Associates, Cheektowaga, New York, USA. (Dr. Eddib).
Background: Sacrocolpopexy has become a favored treatment of pelvic organ prolapse due to its durability and efficacy. Sacrocolpopexy has not been standardized and there is no categorization scheme to facilitate communication or research efforts for the procedure. A systematic review was conducted to facilitate construction of a classification system for sacrocolpopexy based on extent of vaginal dissection described in the medical literature.

Objectives: To compare the values of ultrasound and clinical parameters for predicting outcomes of induction of labor (IOL) among healthy nulliparous women with a singleton, term cephalic pregnancy.
Methods: The cervical length, cervical strain elastography, posterior cervical angle, head-perineum distance, Bishop score, and maternal parameters were assessed before IOL with a combined method-Foley catheter and Misoprostol perorally. The main outcome was vaginal delivery.
