Background: The anterior vaginal wall is frequently affected by prolapse, which is frequently treated with anterior colporrhaphy. However, this repair has a high recurrence rate, and no standardized approach exists. Our study aimed to compare two suture techniques concerning postoperative outcomes. Methods: This randomized, single-center trial invo...

Introduction and Hypothesis Sacrospinous hysteropexy is one of the preeminent uterus-preserving surgical techniques for treating pelvic organ prolapse supported by level one evidence. As training on models greatly improves surgical skills and outcomes, we developed a simple and inexpensive model to simulate sacrospinous hysteropexy. Methods A step...
Article
(Abstracted from Urogynecology 2024;30:714–720) The most common surgical technique for apical pelvic organ prolapse involves a hysterectomy, but uterine-preserving surgeries have become more common and studies have shown many women prefer them. Though uterine-preserving procedures are rising in popularity, long-term outcomes are still under-studied...

Importance There are still doubts about long-term satisfaction rates of native tissue uterine preserving surgical techniques for pelvic organ prolapse. Objective The objective of this study was to compare long-term subjective success rates and satisfaction rates between vaginal sacrospinous hysteropexy (SSHP) and vaginal hysterectomy with uterosac...
Article
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. Methods: All patients who we...

Introduction and hypothesis In women, the risk of pelvic floor prolapse is known to be associated with age and parity. Different studies suggested that it is also related to pelvic dimensions, e.g. biomechanical modelling showed that a larger pelvic canal results in higher values of displacement, stress and strain in the pelvic floor muscles, which...
