Active clinical trials for "Urinary Bladder, Neurogenic"

The purpose of this study is to investigate afferent and cortical activities during bladder filling under different stimulations of the lower urinary tract. The participants of the study are healthy test persons and patients with overactive bladder.

The lower urinary tract is innervated by the autonomous (sympathetic, parasympathetic) and the somatic nervous system. Afferent information from the lower urinary tract (LUT) (e.g. filling state and volume of the urinary bladder) is conducted via the dorsal roots to the sacral spinal cord and from there to the pontine micturition center (PMC) in the brain stem. The PMC has several connections to other cortical areas. These complex interactions with the cortex enable voluntary control of the LUT and are crucial for urinary continence. The integrity of this neuronal circuit is crucial for an undisturbed function. Deterioration of the nerve fibers due to a systemic neurological disease (e.g. spinal cord injury) can affect LUT function. Neurogenic lower urinary tract dysfunction can lead to urgency, urge incontinence, reduced bladder capacity and secondary deterioration of the upper urinary tract (i.e. kidneys). First-line therapy of neurogenic detrusor overactivity contains antimuscarinic treatment. In case of side effects or remaining detrusor overactivity, nerve stimulation (e.g. sacral neuromodulation and in effect nerve tibialis stimulation) is an accepted therapy option. The precise mechanism of action of these neuro-modulatory procedures is still unknown. Utilizing state-of-the-art neuroimaging techniques, we intend to investigate the functional activation pattern after afferent tibialis nerve stimulation as well as the association with the architecture of the sacral roots. We aime to get a better insight into functional neuromodulation and central nervous processing. The study aim is to evaluate the feasibility in healthy subjects as a pilot study for the application of these method in patients with chronic, incomplete spinal cord injury.

This study will describe the prescription conditions of botulinum toxin Type A (Botox®) injection for the treatment of urinary incontinence due to neurogenic detrusor overactivity (NDO) or idiopathic overactive bladder (IOAB) as per standard of care in clinical practice in France.

Bladder management has a major impact on the quality of life in patients with neurogenic bladder dysfunction. This a prospective investigation of the effects of the method for bladder evacuation on the health-related quality of life in patients with neurogenic bladder dysfunction. The changes in health-related quality of life over time (longitudinal investigation) and the differences between the different methods for bladder evacuation will be investigated. Patients will be given a standardized and validated questionnaire annually for 10 years.

The purpose of this study is to compare compact intermittent catheters with standard coated intermittent catheters with regard to quality of life, using the Intermittent Self-Catheterisation Quality of life Measure.

The Catheter Science C3 "Umbrella Catheter" has been developed for management of urinary retention in patients who are either using a Foley or Self Intermittent Catheter. This device is inserted into the bladder in an extended state and once the stylet is removed the device folds into collapsed state. A thread is attached to the device and traverses thru the urethra and is attached to a bobber. With gentle traction on the thread the device engages the bladder neck and the central tube extends which allows for the flow of urine. Once voiding is complete, the thread is released and the device collapses back to the folded state into the bladder. Each voiding cycle is accomplished in a similar fashion. This is a novel technique in which the bladder is catheterized with the device from within the bladder into the bladder neck and urethra. The standard self catheter technique is for placement of a catheter from the outside into the urethra and into the bladder.

Lower urinary tract dysfunction (LUTD) is a very common complication of urological, gynecological, neurological, metabolic, inflammatory or tumor disease. LUTD is not an inevitable condition, the investigators can help in many ways. Modern clinical examinations like urodynamics allow for patient tailored treatment strategies. Urodynamics however, even if minimal invasive, may lead to urinary tract infections and are very expensive4. Aim of this study is to evaluate in the long-term perspective what patients profit of urodynamic examinations and in what patients the investigators could resign to perform urodynamics in the future and or in what patients the interval of urodynamics could be extended. Main objective is to follow in a long-term prospective cohort study, patients suffering of lower urinary tract dysfunction (LUTD). In this observational study the investigators will include all patient undergoing clinical routine urodynamic examination to better address what is the normal course of LUTD with and without Treatment. The aim is to have a prospective urodynamics database allowing to answer questions related to urodynamics.

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.

Most patients with spinal cord injury suffer from bladder dysfunction which may - especially in the long-term - impair renal function. Improved treatment during the last decades improved life expectancy and quality of life. This study evaluates the bladder function in the long-term after spinal cord injury.

The objective of the study is to describe the current status of MS patients with urinary disorders in Lebanon, and to demonstrate whether invasive investigations improve the management of these patients compared to an optimal non-invasive approach.
