Article Abstract
Introduction And Hypothesis: We hypothesized that applying cervical suction and persistent tension can develop a novel and efficient rat model of pelvic organ prolapse.
Methods: Fifteen rats underwent pilot testing to optimize the protocol. Sixteen rats were subjected to pelvic organ prolapse induction by cervical suction and constant traction, while five rats served as controls. The pelvic organ prolapse rats were assessed by a Rat Pelvic Organ Prolapse Quantification system at different time points, and their diet, urine, and stool were monitored for 21 days. The pelvic organ prolapse rats were also evaluated for urinary incontinence, urinary retention, leak point pressure, and vaginal histopathology at 21 days after operation.
Results: This rat model demonstrated pelvic floor prolapse in anatomic level, as well as physiological variations (urine incontinence, urinary retention) and pathological changes (collagen fracture, decreased collagen density).
Conclusions: This is the first establishment of the pelvic organ prolapse rat model with all compartment defects, which provides a valuable tool for elucidating pelvic organ prolapse mechanisms and evaluating potential interventions.

Background: Actinomyces graevenitzii is a relatively uncommon Actinomyces species, which is an oral species and predominantly recovered from respiratory locations [1,2]. It is a gram-positive anaerobic bacteria or microaerobic filamentation bacteria, which can induce pyogenic and granulomatous inflammation characterized by swelling and concomitant pus, sinus formation, and the formation of yellow sulfur granules. All tissues and organs can be infected; the most common type involves the neck and face (55%), followed by the abdominal and pelvic cavities (20%).

Introduction Pelvic organ prolapse (POP) affects up to 30% of women during their lifetime and significantly impairs quality of life. In Japan, laparoscopic sacrocolpopexy was covered by national insurance starting in 2014 and has become an established treatment option. Objective This study evaluates the long-term outcomes of POP surgery, including recurrence and complications, seven years after the introduction of sacrocolpopexy at our institution.

Aim: This study aimed to compare short- and long-term surgical outcomes between robotic sacrocolpopexy (RSC) and laparoscopic sacrocolpopexy (LSC), performed with concomitant total hysterectomy, in patients with symptomatic pelvic organ prolapse (POP).
Methods: This retrospective cohort study included 167 women who underwent RSC (n = 113) or LSC (n = 54) with hysterectomy for uterine prolapse at Kawasaki Medical University between March 2020 and December 2024. Perioperative parameters, complications (Clavien-Dindo classification), and POP recurrence were assessed.
Autonomic Plexuses of the Female Sexual Organs Travel Within Pubocervical and Rectovaginal [Endopelvic] Fascia: A Rationale for 'Nerve-Aware' Vaginal Prolapse Repair.

The connective tissue support of female pelvic viscera-endopelvic fascia-has been studied in fetal and immunohistochemical models to demonstrate its relationship with the autonomic nerves of the female pelvis. Due to a paucity of literature examining the gross anatomical relationships between endopelvic fascia and autonomic nerves in adult female pelvises, it remains unknown whether defects in endopelvic fascia predisposing pelvic organ prolapse and/or manipulation of endopelvic fascia during prolapse repair may be the cause of prolapse-related pelvic pain and sexual dysfunction. Through the dissection of formalin-fixed hemipelvises (n = 10) the present study aimed to map the loci of the visceral branches of the inferior hypogastric plexus and associate them with endopelvic fascia of the female pelvis.

Situs inversus totalis (SIT) is a rare congenital condition characterized by a complete reversal of the internal organ arrangement, presenting significant surgical challenges. While previous cases of colorectal cancer in SIT patients have been reported, cases involving sigmoid colon cancer are sporadic. Here, we present the case of a 68-year-old female with sigmoid colon cancer and SIT.
