OBJECTIVES: To evaluate whether the sling position is associated with particular types of complications in patients undergoing suburethral sling placement for stress urinary incontinence. METHODS: Data from 100 women diagnosed at the Evangelical Hospital Hagen-Haspe with complications after suburethral sling insertion were analyzed. All patients underwent pelvic floor ultrasound to assess: urethral length, sling location in relation to the urethral length (%) and the sling distance to the longitudinal smooth muscle complex of the urethra (the sling-longitudinal smooth muscle distance)...

INTRODUCTION: Women with pelvic floor dysfunction can have tender areas on vaginal examination, which can be treated with trigger-point injections. There are no publications to evaluate the accuracy of pelvic floor muscle injections. METHODS: Trigger-point injections were performed on 2 fresh cadaveric pelvises using a curved nasal cannula guide and 7-in spinal needle. This was performed using our standard template of 2 sets of injections at the 1-, 3-, and 5-o'clock positions distally and proximally...

BACKGROUND: Stress urinary incontinence is a significant problem in young female athletes, but the pathophysiology remains unclear because of the limited knowledge of the pelvic floor support function and limited capability of currently available assessment tools. The aim of our study is to develop an advanced computer modeling tool to better understand the dynamics of the internal pelvic floor during highly transient athletic activities. METHODS: Apelvic model was developed based on high-resolution MRI scans of a healthy nulliparous young female...

OBJECTIVE: Pelvic floor muscle training is effective and necessary in the prevention and treatment of pelvic floor dysfunction during pregnancy and after childbirth. But because of the high prevalence of perineal pain observed in women after childbirth, many women and caregivers fear to start pelvic floor muscle training immediately after childbirth. However, it is unknown whether pelvic floor muscle contractions (PFMC) provoke perineal pain in women shortly after childbirth. Therefore, the main objective is to study whether PFMC performed immediately after childbirth is painful or not...

INTRODUCTION: Vaginal delivery can lead to pelvic floor disorders. Many authors have described pelvic floor injuries that can predict future defects such as urinary incontinence and pelvic organ prolapse. We propose the assessment of urinary stress incontinence and its association with levator ani muscle (LAM) microtrauma (>20% in the levator hiatus area during Valsalva) and macrotraumas (avulsion) identified by 3/4D transperineal ultrasound (3D-TpUS) 36 months post-partum. MATERIALS AND METHODS: This was a prospective observational study including 168 nulliparous women...

AIMS: The overactive bladder syndrome (OAB) is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence. Biofeedback-assisted pelvic muscle therapy (BAPFMT) is a first-line treatment option for OAB. The aims of this study were to determine the efficacy and effectiveness of BAPFMT on symptoms of OAB after 9 weeks of treatment and to detect changes EMG activity of individual pelvic floor muscles (PFM) with the MAPLe. METHODS: Patients were randomly divided into an intervention group that received BAPFMT with the MAPLe or into a control group which received only toilet behavior and lifestyle instructions...

REVIEW
Ahinoam Lev-Sagie, Steven S Witkin
Vulvodynia refers to pain in the vulva of at least 3 months' duration in the absence of a recognized underlying cause. Provoked, localized vestibulodynia is the term used to describe superficial pain confined to the vulvar vestibule, provoked by touch. This review will focus on provoked vestibulodynia with regard to its suggested causative factors and will discuss the role of inflammation, vulvovaginal infections, mucosal nerve fiber proliferation, hormonal associations, central pain mechanisms, pelvic floor muscle dysfunction, and genetic factors...

INTRODUCTION: During laparoscopic abdominoperineal resection (APR) for low rectal cancer, it is difficult to resect the levator muscles and remove a cylindrical specimen without venturing close to the rectal wall to ensure negative circumferential resection margins (CRM). To solve this problem, we developed a needle-guided, laparoscopic, abdominoperineal resection (LAPR) technique. AIM: To present the safety and superiority of our technique, "needle-guided LAPR"...

Urinary incontinence is a common problem among women and it is estimated that between 15 and 55% of them complain of lower urinary symptoms. The most preva¬lent form of urinary incontinence is associated with stress, followed by mixed urinary incontinence and urge urinary incontinence. It is a symptom with several effects on quality of life of women mainly in their social, familiar and sexual domains. Female reproductive and urinary systems share anatomical structures, which promotes that urinary problems interfere with sexual function in females...

BACKGROUND: Although humans experience orgasms with a degree of statistical regularity, they remain among the most enigmatic of sexual responses; difficult to define and even more difficult to study empirically. The question of whether animals experience orgasms is hampered by similar lack of definition and the additional necessity of making inferences from behavioral responses. METHOD: Here we define three behavioral criteria, based on dimensions of the subjective experience of human orgasms described by Mah and Binik, to infer orgasm-like responses (OLRs) in other species: 1) physiological criteria that include pelvic floor and anal muscle contractions that stimulate seminal emission and/or ejaculation in the male, or that stimulate uterine and cervical contractions in the female; 2) short-term behavioral changes that reflect immediate awareness of a pleasurable hedonic reward state during copulation; and 3) long-term behavioral changes that depend on the reward state induced by the OLR, including sexual satiety, the strengthening of patterns of sexual arousal and desire in subsequent copulations, and the generation of conditioned place and partner preferences for contextual and partner-related cues associated with the reward state...

OBJECTIVE: To determine the effect of perineal lacerations on pelvic floor outcomes, including urinary and anal incontinence, sexual function, and perineal pain in a nulliparous cohort with low incidence of episiotomy. METHODS: Nulliparous women were prospectively recruited from a midwifery practice. Pelvic floor symptoms were assessed with validated questionnaires, physical examination, and objective measures in pregnancy and 6 months postpartum. Two trauma groups were compared, those with an intact perineum or only 1st degree lacerations and those with second-, third-, or fourth-degree lacerations...

AIM: Distraction task (DT), which led to a modification of voluntary and involuntary reflex pelvic floor muscle (PFM) activation, might potentiate urinary incontinence, through an alteration of the temporal course between intra-abdominal pressure and PFM contraction. We evaluated whether cognitive rehabilitation (dual-task method) could prevent the effect of a mental distraction task on the reaction time of PFM contraction. METHODS: Thirty-nine healthy volunteers underwent two sessions of electromyographic (EMG) PFM recordings separated by a 2-week interval...
