Assessment of Intermittent Self-Catheterization Procedures in Patients with Neurogenic Lower Urinary Tract Dysfunction: Dutch Translation and Validation of the Intermittent Catheterization Satisfaction Questionnaire, Intermittent Catheterization Acceptance Test, Intermittent Self Catheterization Questionnaire and Intermittent Catheterization Difficulty Questionnaire.

BACKGROUND: Intermittent self-catheterization (ISC) is by far the most appealing therapy to achieve a complete bladder emptying in patients with neurogenic lower urinary tract dysfunction (NLUTD). Four questionnaires have been developed in French in order to assess patient's satisfaction, difficulties and acceptance of this technique. OBJECTIVES: The aim of this study was to translate, culturally adapt and validate Dutch versions of the Intermittent Catheterization Satisfaction Questionnaire (InCaSaQ), the Intermittent Catheterization Acceptance Test (ICAT), the Intermittent Self Catheterization Questionnaire (ISCQ) and the Intermittent Catheterization Difficulty Questionnaire (ICDQ). METHODS: (1) Translation and cross-cultural adaptation of the questionnaires were performed according to the standardized guidelines. (2) The test of the pre-final version was performed by a group of bilingual lay people by comparing the original version of the questionnaires and the back translated one, assessing the comparability of language and comparability of interpretation. (3) Problematic issues were reviewed for correction. (4) Reliability was examined by intra-class correlation coefficients (ICC) statistics and Cronbach alpha analysis. RESULTS: Pre-test by 45 raters who are fluent in the source language led to an adapted and improved version of the translated questionnaires. Fifty native Dutch-speaking patients performing ISC (>6 months) due to an NLUTD were prospectively included. InCaSaQ, ICAT, ISCQ and ICDQ showed good internal consistency (α respectively (test and re-test): 0.79-0.88, 0.88-0.92, 0.85-0.88, and 0.88-0.86) and reproducibility (ICC respectively 0.77, 0.84, 0.84, and 0.87). CONCLUSION: The translated versions of InCaSaQ, ICAT, ISCQ and ICDQ are reliable and valid, allowing self-reported assessment of satisfaction, acceptance, difficulties and quality of life related to ISC in Dutch-speaking patients with NLUTD.

Transcutaneous posterior tibial nerve stimulation for treatment of the overactive bladder syndrome in multiple sclerosis: results of a multicenter prospective study.

AIMS: Electrostimulation is an established therapeutic option for neurogenic urinary disorders. The aim of this study was to investigate the efficacy of the noninvasive technique of transcutaneous posterior tibial nerve stimulation (TPTNS) in patients with multiple sclerosis (MS) and troublesome symptoms of an overactive bladder (OAB). METHODS: A multicentric study enrolled 70 MS patients, suffering from OAB for a 3-month study period. INTERVENTION: Daily sessions of 20 min of TPTNS were provided. No change of associated treatments during the study period. The primary outcome measurement was Urgency and Frequency reported by bladder diary and symptom score performed before the treatment (Day 0, D0) and at D30 and D90. The secondary outcomes measurements were continence, symptom score, quality of life, psychosocial burden at DO, D30, and D90 and cystometry at baseline, with and without TPTNS and at D90. RESULTS: Clinical improvement of OAB was shown in 82.6% and 83.3% of the patients on D30 and D90, respectively, with significant improvement of primary and secondary outcomes compared to baseline. The initial acute cystometric response to TPTNS was positive in 51.2% of the patients (increase of >30% of cystometric capacity and/or reflex volume), without correlation with TPTNS clinical efficiency. The procedure was well tolerated. CONCLUSIONS: Chronic TPTNS appears to be effective in the management of severe OAB in MS, without compromising bladder emptying or inducing side effect. Treatment may be effective even in the absence of an acute cystometric effect. Additional works are required to demonstrate long-term efficacy of TPTNS.

Qualiveen, a urinary-disorder specific instrument: 0.5 corresponds to the minimal important difference.

OBJECTIVE: This study assessed the interpretability of changes in Qualiveen, a specific health-related quality-of-life (HRQOL) questionnaire for urinary disorders (UD) in multiple sclerosis (MS) patients. Qualiveen has 30 items focusing on four aspects of patients' lives related to their urinary problems: bother with limitations (nine items), frequency of limitations (eight items), fears (eight items), and feelings (five items). Response options are framed as 5-point Likert-type scales, and scores on each domain range from 0 to 4. STUDY DESIGN AND SETTING: One hundred twenty-one MS patients with UD completed Qualiveen at baseline and 2-10 weeks later. At the second visit, patients also made global ratings of change in urinary HRQOL (GRC) with a 15-point scale from -7 to +7. We addressed the validity of GRC by examining its relationships with pre- and post-Qualiveen scores and determined the mean change in score on each Qualiveen domain associated with small, moderate, and large changes in the corresponding GRC. RESULTS: The correlation of the change score with the corresponding GRC was substantially stronger than the correlation with either pre- or post-Qualiveen score, establishing the validity of the GRC. In all domains, a within-patient change in Qualiveen score of approximately 0.5 (range: 0.36-0.72) represents the minimal important difference. A change in score of approximately 0.7 corresponds to a moderate change in quality of life (range: 0.55-0.86). CONCLUSIONS: These estimates will help in interpreting the results of subsequent studies that use Qualiveen to examine the impact of interventions designed to improve urinary-specific HRQOL.
