Filter by:This study will look at how pre-test anxiety levels affect the reproducibility of symptoms during routine urodynamic testing in women. Urodynamics is a test that assesses the function of the lower urinary tract, including the bladder.
The study aims to evaluate the efficacy of prophylactic tamsulosin in reducing the incidence of postoperative urinary retention in primary total knee and hip arthroplasty patients.
The purpose of this study is to determine if tamsulosin ("FLOMAX") is effective in preventing post-operative urinary retention following abdominal surgery. Post-operative urinary retention is a common post-operative complication, occurring in up to 30% of patients undergoing abdominal surgery. It can be described as the inability to initiate urination or properly empty one's bladder following surgery. It is usually self-limited, but it requires the use of catheterization to empty the bladder in order to prevent further injury to the bladder or kidneys and to relief the discomfort of a full bladder. Tamsulosin is a medication that is commonly used in men with urinary symptoms related to an enlarged prostate. There is some evidence to suggest that it may also potentially be beneficial for preventing post-operative urinary retention. Therefore, in this research study, subjects scheduled for abdominal surgery will be randomly assigned to take either tamsulosin once-daily or placebo once-daily for one week leading up to surgery, and up to several days after surgery. Urinary function will be assessed and compared between these two treatments. The hypothesis is that tamsulosin will reduce the rate of postoperative urinary retention compared to placebo.
This study aimed to evaluate the effectiveness of adjuvant electroacupuncture therapy for the post-stroke patients with urinary retention under conventional treatments, compared with sham electroacupuncture.
This is a prospective, open-label, Phase 1, single center study evaluating the safety and efficacy of Autologous Muscle Derived Cells as a treatment for chronic Underactive Bladder.
Hypothesis / aims of study Urinary retention is uncommon in young women, and one cause is a primary disorder of urethral sphincter relaxation, characterised by an elevated urethral pressure profile and specific findings in the urethral sphincter EMG (Fowler's Syndrome). Women may present with symptoms of obstructed voiding or complete urinary retention. Clean intermittent self-catheterisation is often painful to perform and currently, the only treatment to show benefit is sacral neuromodulation. This aim of this pilot study is to assess the efficacy of urethral sphincter injections of botulinum toxin, defined as improvement of flow rates by more than 50%, improvement in residual volume and scores on the IPSS questionnaire, and safety, in women with Fowler's Syndrome. Study design, materials and methods In this open label pilot institutional review board approved study, ten women with a primary disorder of urethral sphincter relaxation (elevated urethral pressure profile (UPP), sphincter volume and abnormal EMG) presenting with obstructed voiding (n=5) or in complete urinary retention (n=5) are recruited from a single tertiary referral centre. Baseline symptoms are being assessed using the IPSS questionnaire, and urinary flow and post-void residual volume were measured. After 2% lidocaine injection, 100U of onabotulinumtoxintypeA is being injected into the striated urethral sphincter, divided on either side, under EMG guidance. Patients are being reviewed at weeks 1, 4 and 10 post-treatment and symptoms are reassessed using the IPSS questionnaire, and urinary flow and post-void residual volume are being measured. The UPP is being repeated at week 4.
Acute urinary retention is one of the most common complications after surgery and anesthesia. Micturition depends on coordinated actions between the detrusor muscle and the external urethral sphincter. Under the influence of epidural analgesia, patients may not feel the sensation of bladder filling, which can result in urinary retention and bladder overdistension. Overfilling of the bladder can stretch and in some cases permanently damage the detrusor muscle. Because epidural anesthesia can be performed at various levels of the spinal cord, it is possible to block only a portion of the spinal cord (segmental blockade). Thoracic epidural analgesia with bupivacaine significantly inhibits the detrusor muscle during voiding, resulting in clinically relevant post void residuals which required monitoring or transurethral catheterisation. This bladder muscle inhibition is comparable to a motor blockade. The epidural administration of ropivacaine during labour results in a clinically relevant reduction of motor blocks. The hypothesis is that thoracic epidural analgesia with the local anesthetics ropivacaine leads to less significant changes in bladder function than bupivacaine as a control group, in patients undergoing lumbotomy incision for renal surgery.
Urinary retention is a common complication of epidural analgesia. Auriculotherapy could prevent this complication. This study will be performed among men receiving thoracic epidural analgesia after thoracic surgery.
To establish whether the administration of FLOMAX® improves the outcome of a trial without catheter (TWOC) after an episode of acute urinary retention and to determine whether spontaneous voiding is maintained over the course of six months of active treatment
Ischemic stroke of the spinal cord is a rare disease accounting for about 1% of all ischemic events in the central nervous system (CNS). In most cases the consequences are catastrophic, with a high rate of severe functional disability and mortality rate up to 30%. Ischemic stroke of the spinal cord can arise from: 1. Dissection of the aorta. 2. Aneurism in the aorta. 3. Atherosclerotic disease of the aorta or vertebral arteries. 4. Spinal surgeries. 5. Spinal AVM. 6. Embolism from cardiac origin. 7. Occlusion of radicular artery. Onset is usually sudden, reaching maximal intensity in hours until the patient becomes paralyzed in two or in all four limbs. In most cases the damage is in the Anterior Spinal Artery (ASA). The disease is expressed with motor weakness accompanied by disturbance of temperature and superficial sensation, urinary retention or bowel disorder, with preserved position and vibration sense. The differential diagnosis of ischemic spinal cord includes diseases such as acute myelitis of the spinal cord or acute demyelinating polyneuropathy like Guillan Barree Syndrome (GBS). Therefore in order to reach the appropriate diagnosis in most cases an urgent MRI of the spinal cord is necessary upon arrival in the emergency department. One of the treatments to acute ischemic stroke is providing thrombolysis. As tested and validated in numerous studies for ischemic events in the brain, until today no validated study in ischemic spinal stroke using thrombolysis has been completed.
