Pelvic organ prolapse (POP) affects millions of women globally, impacting their quality of life and potentially influencing family planning decisions. This study aimed to assess the impact of uterus-preserving prolapse surgery on the sexual function, desire for children, and pregnancy outcomes in premenopausal women with symptomatic POP. A survey study was conducted among patients who underwent sacrospinous hysteropexy at a tertiary hospital between 2001 and 2021.

Article Synopsis
  • The risk of urinary tract infections (UTIs) is highly hereditary, with lifetime susceptibility observed from childhood into adulthood, but there's a lack of comprehensive syntheses of genetic studies.
  • This study systematically reviewed genetic polymorphisms linked to UTIs in both children and adults, assessing the strength and reliability of those associations.
  • The analysis included 22 studies, finding notable associations with specific genetic variations (CXCR1, IL8, TGF, TLR4, and VDR) particularly in pediatric UTIs, and confirming CXCR1's link with adult UTIs as well.

Purpose Of The Research: Vaginal pessary use is an established, non-surgical treatment option for pelvic organ prolapse. While satisfaction rates are initially high, they seem to decline over time. We aimed to determine the median duration of pessary use among our patients and to evaluate reasons for discontinuation.

Introduction And Hypothesis: Botulinum toxin (BoNT) is a widely used treatment for overactive bladder (OAB). Despite its common use, no standardized treatment regimen exists so far. The aim of this survey was to evaluate the variation in perioperative treatment strategies among members of the German-speaking urogynecologic societies.

Postoperative wound-site bleeding, tissue inflammation and seroma formation are well-known complications in the field of breast surgery. Hemostatic agents consisting of polysaccharides may be used intra-operatively to minimise postoperative complications. We conducted a prospective randomised-controlled, single-centre study including 136 patients undergoing breast-conserving surgery for invasive or intraductal breast cancer.

Introduction And Hypothesis: This manuscript is the International Urogynecology Consultation (IUC) on pelvic organ prolapse (POP) chapter one, committee three, on the Pathophysiology of Pelvic Organ Prolapse assessing genetics, pregnancy, labor and delivery, age and menopause and animal models.

Materials And Methods: An international group of urogynecologists and basic scientists performed comprehensive literature searches using pre-specified terms in selected biomedical databases to summarize the current knowledge on the pathophysiology of the development of POP, exploring specifically factors including (1) genetics, (2) pregnancy, labor and delivery, (3) age and menopause and (4) non-genetic animal models. This manuscript represents the summary of three systematic reviews with meta-analyses and one narrative review, to which a basic scientific comment on the current understanding of pathophysiologic mechanisms was added.

Despite an estimated prevalence of 13% in women, the exact etiology of non-neurogenic overactive bladder syndrome is unclear. The aim of our study was to gain a better understanding of the pathophysiology of female overactive bladder syndrome by mapping the urinary proteomic profile. We collected urine samples of 20 patients with overactive bladder syndrome and of 20 controls.

Introduction And Hypothesis: Family and twin studies demonstrate that pelvic organ prolapse (POP) is heritable, but the genetic etiology is poorly understood. This review aimed to identify genetic loci and specific polymorphisms associated with POP, while assessing the strength, consistency, and risk of bias among reported associations.

Methods: Updating an earlier systematic review, PubMed and HuGE Navigator as well as relevant conference abstracts were searched using genetic and phenotype keywords from 2015 to 2020.

Article Synopsis
  • A study evaluated changes in serum markers in women with polycystic ovary syndrome (PCOS) during two consecutive clomiphene citrate (CC) treatment cycles that didn’t result in pregnancy.
  • The study included 41 anovulatory PCOS patients receiving CC and 24 control patients, measuring levels of hormones like LH, FSH, and AMH.
  • Results showed decreases in LH, LH:FSH ratio, and AMH in the CC group, with an increase in SHBG, but the overall clinical significance of these changes is considered minor.

Background: Vaginismus affects up to 1% of the female population and often represents a physical manifestation of an underlying psychological problem. Our objective was to investigate the psychosomatic impact of vaginismus in pregnant women and evaluate the quality of their therapeutic care in Tunisia.

Methods: We included pregnant patients with vaginismus who presented at our obstetric emergency department between October 2016 and March 2017.

Introduction And Hypothesis: Previous studies have indicated a hereditary component of stress urinary incontinence; however, evidence on candidate genes or single-nucleotide polymorphisms (SNPs) is scarce. We hypothesize a genetic association of female stress urinary incontinence based on significant differences of the urinary and serum proteomic pattern in the identical study population.

Methods: Case-control study of 19 patients and 19 controls.

Objective: To assess associations between anterior and/or fundal uterine leiomyoma and overactive bladder syndrome.

Methods: The present cohort study recruited women diagnosed with fundal/anterior uterine leiomyoma by standardized transvaginal ultrasonography at the Medical University of Vienna, Austria, between January 1, 2010, and December 31, 2013, in addition to an age-matched control group of women without uterine leiomyoma. The International Consultation on Incontinence Questionnaire Overactive Bladder Module (ICIQ-OAB) was mailed to all eligible participants.

Introduction: The aim of this study was to compare ultrasound-guided local methotrexate (MTX) vs. systemic methotrexate in uterine ectopic pregnancy regarding the beta human chorionic gonadotropin (hCG) clearance duration.

Material And Methods: Patients with interstitial pregnancy, cervical pregnancy or cesarean scar pregnancy were included.

The pathophysiology of Stress Urinary Incontinence (SUI) is poorly understood. The aim of this study was to identify the serum proteomic profile in patients with SUI and to replicate findings from a preceding study in which a significant difference in the urinary proteome was identified. Serum samples were collected from 38 patients (19 SUI; 19 matched, continent controls).

This is a clinical trial update without results. The aim of the trial is to identify a urinary proteomic pattern, including gender aspects, for patients with overactive bladder syndrome in comparison to healthy controls.

Objective: Transplantation results in a 5-time elevated risk for a variety of malignancies (Kaposi sarcoma, skin, liver, lung, gastrointestinal cancer). A patient's risk for malignancies could be of particular interest for the follow-up programs of patients and risk adaption after kidney transplantation. The aim of this study was to identify independent risk factors for de novo malignancies in women after renal transplantation.
