Filter by:The aim of this study is to develop improved methods of restoring function to the neurogenic bladder, using electrical stimulation without cutting nerves in patients with spinal cord injury. The investigators will test 5-10 subjects with existing sacral anterior root stimulation (SARS) devices and look at the effects of high frequency (up to 600Hz) compared to the usual low frequency stimulation on bladder function. The investigators are particularly interested in whether it is possible to reproduce a 'functional' dorzal rhizotomy using high frequency stimulation of the S2 efferent nerves
Surgical outcomes of bladder neck surgery in children with neurogenic bladder. Consequences on bladder voiding.
Retrospective monocentric study of the outcomes of patients with neurogenic bladder, who had a urinary artificial sphincter before the age of 18 years old. Hypothesis: what was the impact of the urinary artificial sphincter on the global management of the patient.
The purpose of this study is to test a new ultrasound method called Quantitative Ultrasound Bladder Vibrometry to detect abnormal bladder function.
This phase 0 trial tests the feasibility, functionality, and sustainability of vascularized composite bladder allograft transplantation in treating patients with terminal bladder pathology. A vascularized bladder allograft transplantation may provide a more durable and better-tolerated alternative to standard urinary diversion, which employs bowel. A robotic surgical approach will be employed.
There are many studies in the literature on healthy children with lower urinary tract dysfunction (LUTD), but there are limited number of studies in children with cerebral palsy (CP) with LUTD. This study aim to contribute to the literature by examining the effectiveness of transcutaneous electrical nerve stimulation (TENS) and abdominal massage in the treatment of children with CP with LUTD and comparing the superiority of the two treatment methods to each other.
Increasing knowledge on rectal motility and bladder-rectum cross-talk has been published in recent years. However, whether bladder filling factors during multichannel urodynamic studies affect rectal contraction (RC) parameters has not been studied. The primary aim of this study is to assess the impact of bladder filling and desire to void on rectal contraction amplitude or frequency. Secondary objectives are to determine any significant change in rectal parameters depending on clinical and urodynamic factors or treatment. All patients referred for urodynamic assessment and with studies positive for rectal contractions as defined by the international continence society (ICS) will be included. Abdominal pressure will be measured using a T-doc air charged abdominal catheter inserted 10 cm from the anal margin. Standardized urodynamic evaluation will be conducted following ICS guidelines. Mean amplitude, maximal amplitude (cmH20) and mean frequency of rectal contractions on all urodynamic studies will be visually measured on the recording software and compared depending on bladder sensation (First Desire to void (FDV), Strong Desire to Void (SDV) and filling volume (200ml, 400ml). Demographic data (age, sex, BMI), underlying neurological disease, clinical symptoms, and scores (Neurogenic Bladder Symptom Score, Bristol Score, Cleveland Score), urodynamic parameters and treatments will be collected. Time since last defecation and meal will also be collected. This prospective observational study will be conducted in a Neuro-Urology department of a French university hospital. All the patients included are referred for multichannel urodynamic assessment.
The over-arching aim of this study is to evaluate the effects of two specific anti-cancer chemotherapies, vincristine and doxorubicin, on bladder function and urine composition.
This study is a unique one as it si done for first time to all patients following bladder injury in PAS surgery. Bladder function will be assessed by urodynamic study.
The purpose of this study is to establish if concomitant renal and vascularized urinary bladder allograft transplantation is feasible.
