Five years follow-up study and failures analysis of Botulinum toxin repeated injections to treat neurogenic detrusor overactivity.

INTRODUCTION: The aim of this work was to follow prospectively a cohort of patients suffering from neurogenic overactive bladder, treated by botulinum toxin A, study the efficiency of this treatment, analyse the primary failures, secondary and surrender. PATIENTS AND METHODS: Thirty-one patients suffering from neurogenic OAB received a detrusor injection of 300 units of Botox™ (ALLERGAN, Irvine, CA) and were followed prospectively (median 5 years). They were evaluated by voiding diary, Qualiveen™ questionnary and urodynamics before treatment, 2 months after the first injection and the last re-injection. RESULTS: Five years after the beginning of the treatment, 17 patients of 31 (54.8%) were still injected, it means 60.7% of the primary responders. Eleven patients had left up the treatment, after at least one effective injection. We identified three reasons of surrender: echapment of treatment for two patients of 11 (7.1%); cessation of self catheterize for six patients of 11 (54.6%) and the surrender of the treatment without clinical or urodynamical failure, for three patients of 11 (27.3%). Although the cessation of self catheterize was more frequent for patients suffering from multiple sclerosis, no predictive factor of surrender was statically significant. CONCLUSION: In this series, bladder BTA injections was efficient at middle term to treat neurogenic OAB. The echapment was a rare event (7%). The major cause of surrender was the increase difficulty to self catheterize, due to progression of disability, more frequent for patients suffering of multiple sclerosis.

Self-catheterization acquisition after hand reanimation protocols in C5-C7 tetraplegic patients.

STUDY DESIGN: Case series from a prospectively acquired database and phone survey. OBJECTIVES: To assess the efficacy of upper limb reanimation (ULR) protocols on acquisition of intermittent self-catheterization (ISC) in C5-C7 ASIA tetraplegic patients. SETTING: University Hospital, Paris, France. METHODS: A prospectively acquired database of 152 tetraplegic patients followed in ULR consultation between 1997 and 2008 in a rehabilitation unit was studied. A total of 20 patients met the inclusion criteria, which mainly were traumatic C5-C7 tetraplegic adult patients who were unable to perform ISC, and who benefited from ULR with the objectives of improving hand abilities and of ISC acquisition, through urethral orifice for males or via a continent urinary stoma for females. The main outcome measure was ISC acquisition (ISC+) proportion. Population characteristics and secondary outcome measures: ISC+/ISC- patients were compared regarding epidemiological and surgical data, key-grip strength, patient global improvement score, activities of daily living and quality of life (PGI-I, Wuolle questionnaire, verbal rating scale). RESULTS: ISC+ was 75%. It depended on key-grip strength (P<0.05) and led to a statistically significant improvement of urinary status compared with ISC- patients (P<0.01). ULR improved patients' abilities and QoL in both ISC+ and ISC- patients. CONCLUSION: ULR protocols allow ISC in most C5-C7 tetraplegic patients. Multidisciplinary care with surgeons and PRM physicians improves patients' vital and functional prognosis by changing their urological-management method.
