Barium proctography vs magnetic resonance proctography for pelvic floor disorders: a comparative study

Aim Accurate and reliable imaging of pelvic floor dynamics is important for tailoring treatment in pelvic floor disorders; however, two imaging modalities are available. Barium proctography (BaP) is widely used, but involves a significant radiation dose. Magnetic resonance (MR) proctography allows visualization of all pelvic midline structures but patients are supine. This project investigates whether there are measurable differences between BaP and MR proctography. Patient preference for the tests was also investigated. Methods Consecutive patients referred for BaP were invited to participate (National Research Ethics Service approved). Participants underwent BaP in Poole and MR proctography in Dorchester. Proctograms were reported by a consultant radiologist with pelvic floor subspecialization. Results A total of 71 patients were recruited. Both tests were carried out on 42 patients. Complete rectal emptying was observed in 29% (12/42) on BaP and in 2% (1/42) on MR proctography. Anismus was reported in 29% (12/42) on BaP and 43% (18/42) on MR proctography. MR proctography missed 31% (11/35) of rectal intussusception detected on BaP. In 10 of these cases no rectal evacuation was achieved during MR proctography. The measure of agreement between grade of rectal intussusception was fair (κ = 0.260) although MR proctography tended to underestimate the grade. Rectoceles were extremely common but clinically relevant differences in size were evident. Patients reported that they found MR proctography less embarrassing but harder to empty their bowel. Conclusions The results demonstrate that MR proctography under‐reports pelvic floor abnormalities especially where there has been poor rectal evacuation.

Australian pelvic floor questionnaire: a validated interviewer-administered pelvic floor questionnaire for routine clinic and research

The aim of this study was to design and validate an interviewer-administered pelvic floor questionnaire that integrates bladder, bowel and sexual function, pelvic organ prolapse, severity, bothersomeness and condition-specific quality of life. Validation testing of the questionnaire was performed using data from 106 urogynaecological patients and a separately sampled community cohort of 49 women. Missing data did not exceed 2% for any question. It distinguished community and urogynaecological populations regarding pelvic floor dysfunction. The bladder domain correlated with the short version of the Urogenital Distress Inventory, bowel function with an established bowel questionnaire and prolapse symptoms with the International Continence Society prolapse quantification. Sexual function assessment reflected scores on the McCoy Female Sexuality Questionnaire. Cronbach’s α coefficients were acceptable in all domains. Kappa coefficients of agreement for the test–retest analyses varied from 0.5 to 1.0. The interviewer-administered pelvic floor questionnaire assessed pelvic floor function in a reproducible and valid fashion in a typical urogynaecological clinic. The validation of the interviewer-administered pelvic floor questionnaire was presented at the Annual Meeting of the International Continence Society in 2004, Paris (podium presentation; extended abstract): A validated female pelvic floor questionnaire for clinicians and researchers, Baessler K, O’Neill S, Maher C, Battistutta D, Neurourol Urodynam 2004; 23: 398–399.

Development and validation of the pelvic floor inventories Leiden (PelFIs)

AIMS: To evaluate the validity and reliability in Dutch of the Pelvic Floor Inventories Leiden (PelFIs) for men and women, an administered questionnaire, developed to create a condition-specific pelvic floor questionnaire addressing all symptoms of micturition, defecation and sexual dysfunction related to pelvic floor dysfunction. METHODS: The PelFIs is an 83-item instrument for women and 76-item instrument for men measuring the degree of pelvic floor dysfunction, containing nine different domains. Questions have been selected which, from a clinical point of view, should configure a domain. The PelFIs was administered to healthy volunteers (N = 120), and to patients (N = 100). Reliability of the PelFIs was assessed by internal consistency and test-retest reliability. Construct validity was established comparing healthy volunteers and patients by intercorrelating the domains. RESULTS: A total of 220 questionnaires were completed; by 147 women and 73 men. Some domains in the men's questionnaire had a low alpha (alpha) although the overall alpha was good. The overall of the domains for men ranged from 0.53 to 0.90. The internal consistency for the total scale of men's questionnaire was 0.84. The overall of the domains in women ranged from 0.60 to 0.85. The internal consistency of the women's questionnaire was 0.88 for the total scale. Intraclass correlation ranged from 0.65 to 0.88. Differences between healthy volunteers and patients were statistically significant for all domains. CONCLUSION: The PelFIs is a new, practical and conceptually clear questionnaire, which focus on micturition, defecation and/or sexual dysfunction related to pelvic floor dysfunction.     

Evaluation of knowledge and anxiety level of patients visiting the colorectal pelvic floor clinic

OBJECTIVE: Discussing defaecating disorders is difficult for patients and many view anal physiology investigations (ultrasound, manometry, electromyography and pudendal nerve studies) as distasteful. This pilot study sought to assess whether present information sheets supplied to patients and the visit to the colorectal Pelvic Floor Clinic itself influenced patients' knowledge and anxiety. PATIENTS AND METHODS: Thirty Pelvic Floor Clinic patients from Auckland City Hospital were included. Each patient filled in a questionnaire before and after the clinic. This included objective questions about their knowledge of the structure and function of the pelvic floor and satisfaction with and understanding of the information sheet. Both visual analogue scale (VAS) and multiple choice questions (MCQ) were used. Their subjective and objective knowledge were compared. Anxiety was assessed on a visual analogue anxiety scale (VAAS). Results were expressed as VAS scores or percentage correct and relationships were tested using Fisher's Exact test and paired T-test. RESULTS: Subjective knowledge increased in 93% of the patients. The doctor's explanation led to a greater increase in subjective knowledge than the information sheet (35/100 mm, P<0.001 and 10/100 mm, P=0.01, respectively). Subjective improvement in knowledge did not however, translate into an increase in objective knowledge (P=0.63). The information sheet was read by 87% of the patients. The information sheet had reduced anxiety only in 23% of the patients and increased in 10%. Anxiety levels were not significantly influenced by the information sheet, but reduced significantly by the clinic visit in 87% of patients (P<0.001). The mean anxiety level reduced from 44/100 to 12/100 after the clinic visit. CONCLUSION: Anxiety levels are high in those visiting the Pelvic Floor Clinic. It appears that it is the interaction with the doctor that has a profound influence on anxiety levels and subjective knowledge rather than written information.     

Reliability of speed of contraction and endurance dynamometric measurements of the pelvic floor musculature in stress incontinent parous women

AIMS: To evaluate the test-retest reliability of dynamometric measurements of the pelvic floor muscles (PFM) during speed and endurance tests. METHODS: Nineteen parous women suffering from stress urinary incontinence (SUI) participated in the study. Two PFM evaluation sessions were conducted using the dynamometric speculum. For the speed test, the women were instructed to contract maximally and relax as quickly as possible during a 15-s test period. The speed of contraction was quantified by the rate of force development of the first contraction and the number of contractions performed. The maximal strength value attained during the speed test was also extracted from the curves. For the endurance test, the subjects were asked to maintain a maximal contraction for 90 s. The normalized area under the force curve was utilized as the endurance parameter. The reliability of the data was evaluated using the generalizability theory. Two reliability estimates were calculated, the dependability indices (Phi) and the standard error of measurement (SEM), for one measurement session involving one trial. RESULTS: The indices of dependability obtained indicate that the reliability of the speed of contraction and endurance parameters are good (Phi=0.79-0.92). The corresponding SEMs were 1.39 N/s, 1 contraction, 1.00 N, and 298%*s for the rate of force development, number of contractions, maximal strength and normalized area, respectively. CONCLUSION: This study indicates that the speed of contraction and endurance parameters possess good test-retest reliability. The inclusion of these parameters in the PFM assessment is therefore highly recommended for assessing changes in PFM in incontinent women.
