[Transcutaneous tibial nerve stimulation in the overactive bladder syndrome in patients with Parkinson's syndromes]. / Stimulation transcutanée chronique du nerf tibial dans l'hyperactivité vésicale des syndromes parkinsoniens.

OBJECTIVES: To evaluate the efficacy of chronic transcutaneous tibial nerve stimulation (TNS) on overactive bladder syndrome in female patients with Parkinson's disease (PD) and multiple system atrophy (MSA). PATIENTS AND METHODS: A prospective monocentric study enrolled six female patients with PD or MSA suffering from overactive bladder syndrome for a six-week study period. Daily sessions of 20 minutes of TNS were provided. The primary outcome measurement was the Patient Global Impression of Improvement (PGI-I scale). The secondary outcomes measurements were symptom and quality of life scores, bladder diary and urodynamics. The outcomes after 6 weeks of TNS were compared to baseline. RESULTS: TNS was considered as an effective treatment by five patients out of six (83%) who ask to pursue the treatment and were still doing it 6 months after the end of the study. A trend improvement was observed in only two of the secondary evaluation criteria the V8 median score 21/40 to 14/40 (P=0.2) and the maximum cystometric capacity increased from 211 mL ± 106 to 260 mL ± 226 (P=0.6) after SNT. CONCLUSION: Although urodynamics and symptoms scores did not show significant difference, an efficacy of TNS on overactive bladder in PD and MSA is possible. Additional placebo controlled works enrolling more patients are required to ensure these preliminary results.

[Bladder-sphincter disorders associated with Wolfram syndrome]. / Troubles vésicosphinctériens au cours du syndrome de Wolfram.

OBJECTIVES: To identify and describe functional urinary symptoms, uro-nephrological complications and their impact on quality of life in a cohort of patients diagnosed with the Wolfram syndrome (SW). PATIENTS AND METHODS: A transversal descriptive patient's cohort study was performed. The Urinary Symptom Profile (USP) and the International Consultation Incontinence Questionnaire - Female Lower Urinary Tracts Symptoms (ICIQ-FLUTS) were used to evaluate urinary symptoms and their impact on quality of life through direct interviews conducted by telephone. A less than 6-month old renal ultrasound and serum creatinine results were asked to the patient or physician. RESULTS: Thirty-three patients have been contacted and 22 (73%) agreed to participate in this study. Eighteen patients over 22 had spontaneous micturition when four of them had an urinary diversion (two definitive, two temporaries) before being included in this study. Seventy-three percent of patients with spontaneous micturition had urinary symptoms. A severe or moderate symptoms score was noted in 67% (12/18 patients) and 11% (2/18 patients) respectively. CONCLUSION: Functional urinary dysfunctions were frequent and impacted quality of life in more than one half of patients diagnosed with SW in this study. Early diagnostic and regular urological follow-up can improve the quality of life and prevent severe urinary complications.

[Treatment of detrusor-striated sphincter dyssynergia with permanent nitinol urethral stent: results after a minimum follow-up of 2 years]. / Résultats à moyen terme du traitement de la dyssynergie vésicosphinctérienne par sphinctérotomie prothétique permanente.

OBJECTIVES: The aim of this study was to assess the outcomes of nitinol permanent urethral stents used in detrusor-striated sphincter dyssynergia (DSD) treatment on male patients with a spinal cord injury. MATERIALS: We investigated retrospectively all patients treated from 2004 to 2012. A total of 22 patients were included, with an age ranging from 22 to 76 years old. The DSD syndrome was due to spinal cord injury (18) or various spinal cord diseases (four) and treated with a nitinol urethral stent (11 Ultraflex(®) and 11 Mémotherm(®)). Every patient had an urodynamical study. The follow-up reached at least 2 years. RESULTS: The mean follow-up was 56 months (± 14). Complementary procedures after stenting included: five stent prolongation or displacement (mean interval 7.6 months), six bladder neck incisions (12.2 months), three urethrotomy (42 months), ten obstruction treated by laser (47.3 months). Eight patients had a change of their urinary pattern: four underwent ileal conduit diversion, one had a continent urinary diversion, one chose self intermittent catheterization, two were under indwelling catheterization waiting for another treatment. Stent retrieval was either harmful or impossible for four of them. Three patients were free of complementary procedures. CONCLUSIONS: Nitinol urethral stent was an effective treatment initially. However, by the third year, urethral stenosis and hypertrophic growth of the urethral mucosa usually require iterative endoscopic procedures (0.31 per patient per year). Patients treated with permanent uretral stent deserve a yearly endoscopic follow-up. Safety and effectiveness of permanent uretral stent compared to surgical sphincterotomy to treat DSD are discussed.

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.

Post-traumatic syringomyelia and post-traumatic spinal canal stenosis: a direct relationship: review of 75 patients with a spinal cord injury.

This study aims to demonstrate predictive factors for post traumatic syringomyelia (PTS), and in particular to correlate the role of insufficiency of reduction of a spinal fracture with the occurrence of syringomyelia. One hundred and twenty-eight spinal cord injured patients (SCI) were studied during the years 1992 and 1993. Among them, 75 underwent a complete and reliable evaluation including: review of the initial vertebral lesion, and of the surgery report, and a radiological study of the lesion site with standard X-rays, a CT scan, and an MRI. The CT Scan included slices in sagittal reconstructions and in the axial plane at the site of injury with the calculation of a percentage of canal stenosis in the two planes of the space. An MRI was carried out with T1 and T2 weighted images, including sagittal entire cord images in addition to sagittal and axial slices centred on the site of injury. A syrinx was diagnosed in 28% of the patients. The occurrence of a syrinx is significantly correlated with spinal canal stenosis in the sagittal plane (delta D) with a P < 0.001 and in the axial plane (delta S) (P < 0.05). This present study demonstrates the major role of the insufficiency of reduction of the vertebral lesion in the genesis of a syrinx. The quality of the initial treatment of the vertebral injury is the first step in the prevention of a syrinx. The treatment of a syrinx, besides techniques of drainage, must also take into account the spinal realignment.
