INTRODUCTION Pelvic floor dysfunction is recognized to be related to lower urinary tract dysfunction and to lower gastrointestinal symptoms, and is an influential factor in dysfunction and subsequent behavior of the genital system in both men and women. Caregivers should be informed regarding normal pelvic floor function in general and should be able to identify specific aspects of pelvic floor dysfunction in patients with related symptoms. In our hospital, this diagnostic consultation is indicated as Diagnostic Investigation of Pelvic Floor Function (DIPFF). AIM This study looked at pelvic floor dysfunction related to specific complaints. METHODS DIPFF consists of a medical history, a physical examination, including the International Continence Society (ICS) pelvic organ prolapse quantification system in female patients, and a biofeedback registration using a vaginal or anal probe. Based on our experience, we defined an elevated rest tone as greater than 2 microV using intravaginal or intra-anal electromyography. MAIN OUTCOME MEASURES Stratification of patients with a single complaint, a combination of two or three complaints of the micturition, defecation or sexual (all compartments of the pelvic floor) resulted in subgroups of respectively 30, 74, and 133 patients. RESULTS A total of 238 patients with complaints of micturition, defecation, and/or sexual function were included in this study. Electromyographic analysis revealed an elevated rest tone of the pelvic floor in 141 patients. In 184 patients, we found an involuntary relaxation of the pelvic floor. CONCLUSION In our retrospective study, we found that 77.2% of patients who presented to the clinic with urinary, gastro or sexual complaints had measurable pelvic floor dysfunction (69.3% overactive rest tone and 7.9% under active rest tone). In relation to the ICS terminology, there is a need for a well-defined normal vs. elevated rest tone of the pelvic floor.

INTRODUCTION The relationship between sexual abuse and urinary tract symptoms, sexual abuse and gastrointestinal symptoms, or sexual abuse and sexual dysfunction has been described before. A correlation between all these symptoms and sexual abuse has not yet been reported. AIMS The first aim of this study was to document the prevalence rates of reported sexual abuse in a large sample of female patients with complaints of the pelvic floor. The second aim was to evaluate the frequency of complaints in the different domains of the pelvic floor, such as complaints of micturition, defecation, and sexual function, in female patients reporting sexual abuse, and comparing these data with female patients without a history of sexual abuse. METHODS Female patients with pelvic floor complaints were evaluated in a tertiary referral center. History taking was assessed by a pelvic-floor clinician. The number of domains with complaints of patients with a history of sexual abuse was compared with the number of domains with complaints of patients without sexual abuse. MAIN OUTCOME MEASURES The number of patients who reported sexual abuse and the frequency of complaints in the different domains of the pelvic floor. The number of domains of patients with a history of sexual abuse was compared with patients without a history of sexual abuse. RESULTS Twenty-three percent (42/185) of the patients reported a history of sexual abuse. The female patients with a history of sexual abuse had significantly more complaints in three domains of the pelvic floor (35/42) compared with the nonabused (69/143) (83% vs. 48%, P < 0.001). CONCLUSIONS Twenty-three percent of the female patients in a pelvic floor center evaluated by a pelvic-floor clinician reported a history of sexual abuse. This is comparable with the percentage of sexual abuse observed in the population at large. In our sample, the patients with multiple pelvic floor complaints (micturition, defecation, and sexual function) related to pelvic floor dysfunction were more likely to have a history of sexual abuse than the patients with isolated complaints.

INTRODUCTION: Sexual abuse and sexual functioning are topics that health professionals find difficult to discuss. Women who present with pelvic-floor complaints often experience sexual difficulties; therefore, questions regarding sexual function should be a routine part of screening. Furthermore, pelvic-floor complaints are correlated with sexual abuse and asking about abuse should be a routine part of screening as well. Considering the fact that many practitioners have difficulty enquiring about abuse, we have suggested that a questionnaire may be helpful in improving the recognition and management of patients who have a history of sexual abuse. AIM: The efficiency of detecting sexual abuse by a self-administered questionnaire. METHODS: Report of sexual abuse in a self-administered pelvic-floor questionnaire before visiting our outpatient pelvic-floor department was evaluated with the Pelvic Floor Leiden Inventories (PelFIs) administered by a pelvic- floor clinician in a later stage. MAIN OUTCOME MEASURES: The percentage of sexual abuse detected by a taken questionnaire administered by a pelvic-floor clinician not confessed during a previous self-administered questionnaire. RESULTS: Sexual abuse was reported in 20 patients with pelvic-floor dysfunction during administration of the PelFIs and were also evaluated on our pelvic-floor department. Only six of the patients (30%) did not note in the self-administered questionnaire that they had a history of sexual abuse. CONCLUSION: A self-administered questionnaire for pelvic-floor complaints is reliable in detecting sexual abuse and can be helpful in daily practice. Language: en

A new multiple electrode probe, the Multiple Array Probe Leiden (MAPLe), has been developed for biofeedback registration of the individual pelvic floor musculature (PFM). The aim was to determine the reliability and differentiation of electromyography (EMG) signals measured with the MAPLe in healthy volunteers.

PURPOSE We determined whether chronic testicular pain is related to pelvic floor overactivity after ruling out other disease pathology. MATERIALS AND METHODS A total of 41 patients with chronic testicular pain evaluated at our Pelvic Floor Department at a tertiary academic center were included in this retrospective study. All patients underwent standard pelvic floor investigation, including history using a standardized questionnaire and electromyography registration of the pelvic floor. In the questionnaire patients were asked about complaints in 3 domains (micturition, defecation and sexual function) suggestive of pelvic floor dysfunction. Electromyography registration of the pelvic floor was performed. The resting tone of the pelvic floor was considered increased at 3 muV or greater. RESULTS Mean patient age was 48 years. Of the patients 93% had at least 1 symptom suspicious of pelvic floor dysfunction. A total of 22% had complaints in 1 of the domains of micturition, defecation or sexual function, 24% had complaints in 2 domains and 49% had complaints in all 3 domains. On electromyography registration of the pelvic floor 88% of patients appeared to have an increased resting tone of the pelvic floor muscles at a mean of 6.7 muV (normal less than 3). The patients with a normal pelvic floor resting tone were significantly older than those with an increased resting tone (65.6 vs 45.6, p = 0.0001). CONCLUSIONS Chronic testicular pain can be a symptom of pelvic floor overactivity, especially in younger patients. A diagnostic evaluation should be performed when no pathophysiology can be found.
