PURPOSE OF REVIEW: The purpose of this review is to critically analyze the relationship between symptoms of abnormal emptying of the bladder, urgency, pelvic pain, anorectal dysfunction and pelvic organ prolapse (POP) and to present evidence in order to show how many of the above mentioned symptoms can be cured or substantially improved by repair of specific pelvic ligaments. RECENT FINDINGS: In this review, we provide evidence to show how often these dysfunctions occur and how they can be cured in 42-94% by appropriate pelvic floor surgery in the longer term, up to 2 years...

Pelvic disorders can be associated with changes in the biomechanical properties in the muscle, ligaments and/or connective tissue form fascia and ligaments. In this sense, the study of their mechanical behavior is important to understand the structure and function of these biological soft tissues. The aim of this study was to establish the biomechanical properties of the pelvic floor muscles of continent and incontinent women, using an inverse finite element analysis (FEA). The numerical models, including the pubovisceral muscle and pelvic bones were built from magnetic resonance (MR) images acquired at rest...

The pelvic floor guards the passage of the pelvic organs to the exterior. The near-epidemic prevalence of incontinence in women continues to generate interest in the functional anatomy of the pelvic floor. However, due to its complex architecture and poor accessibility, the classical 'dissectional' approach has been unable to come up with a satisfactory description, so that many aspects of its anatomy continue to raise debate. For this reason, we opted for a 'sectional' approach, using the Chinese Visible Human project (four females, 21-35 years) and the Visible Human Project (USA; one female, 59 years) datasets to investigate age-related changes in the architecture of the anterior and middle compartments of the pelvic floor...

Little research has been undertaken regarding pelvic floor muscle function and dysfunction in children. Apart from dysfunctional voiding, whether specific dysfunction of these muscles contributes to different types of childhood incontinence is not documented. The two areas of practice, that is adult and paediatric incontinence, are quite different; nevertheless, there may be lessons to be learned from the extensive work done in pelvic floor dysfunction and rehabilitation in adults. In this paper key points regarding pelvic floor muscle function and dysfunction in adults, and lessons that can be learned from how studies are reported and how muscle function is measured are presented...

We have developed a percutaneously implantable and wireless microstimulator (NuStim®) to exercise the pelvic floor muscles for treatment of stress urinary incontinence. It produces a wide range of charge-regulated electrical stimulation pulses and trains of pulses using a simple electronic circuit that receives power and timing information from an externally generated RF magnetic field. The complete system was validated in vitro and in vivo in preclinical studies demonstrating that the NuStim can be successfully implanted into an effective, low threshold location and the implant can be operated chronically to produce effective and well-tolerated contractions of skeletal muscle...

INTRODUCTION AND HYPOTHESIS: Animal models are essential to further our understanding of the independent and combined function of human pelvic floor muscles (PFMs), as direct studies in women are limited. To assure suitability of the rhesus macaque (RM), we compared RM and human PFM architecture, the strongest predictor of muscle function. We hypothesized that relative to other models, RM best resembles human PFM. METHODS: Major architectural parameters of cadaveric human coccygeus, iliococcygeus, and pubovisceralis (pubococcygeus + puborectalis) and corresponding RM coccygeus, iliocaudalis, and pubovisceralis (pubovaginalis + pubocaudalis) were compared using 1- and 2-way analysis of variance (ANOVA) with post hoc testing...

PURPOSE OF REVIEW: The pelvic floor is a complex assembly of connective tissues and striated muscles that simultaneously counteracts gravitational forces, inertial forces, and intra-abdominal pressures while maintaining the position of the pelvic organs. In 30% of women, injury or failure of the pelvic floor results in pelvic organ prolapse. Surgical treatments have high recurrence rates, due, in part, to a limited understanding of physiologic loading conditions. It is critical to apply biomechanics to help elucidate how altered loading conditions of the pelvis contribute to the development of pelvic organ prolapse and to define surgeries to restore normal support...

BACKGROUND & AIMS: Non-relaxing pelvic floor dysfunction (N-RPFD), or dyssynergic defecation, is the paradoxical contraction and/or impaired relaxation of pelvic floor and anal muscles during defecation. Few studies have evaluated this disorder in patients with an ileal pouch-anal anastomosis (IPAA). We investigated the frequency of N-RPFD in patients with and without chronic pouchitis following IPAA and the effectiveness of biofeedback therapy within this population. METHODS: We conducted a retrospective study of all patients with an IPAA who underwent anorectal manometry (ARM) between January 2000 and March 2015 (n=111)...

Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women...

PURPOSE OF REVIEW: To summarize recent literature about the potential role of chronic exercise on pelvic floor support and function. RECENT FINDINGS: Stress urinary incontinence is common during physical activity. Scant evidence suggests a dose-response association between higher volumes of exercise and urinary incontinence. Athletes do not appear to have greater pelvic floor muscle strength or worse pelvic floor support compared to nonathletes. Pelvic floor muscle electromyographic activity increases substantially as running speeds increase...
