Active clinical trials for "Urinary Bladder, Underactive"

The study objectives of this study are to evaluate the efficacy of ASP8302 compared with placebo in participants with underactive bladder (UAB), to investigate the safety and tolerability of ASP8302 compared with placebo in participants with UAB, to investigate the pharmacokinetics of ASP8302 in participants with UAB and to support the development of the UAB - Patient Reported Outcome (PRO).

To determine the significance of delta Q value (Qmax - Qave) in discrimination between BOO and DU, to avoid invasive studies (pressure flow studies (PFSs)) and replace them with noninvasive study (uroflowmetry).

The study is seeking to understand the needs of patients and healthcare practitioners for an innovation in the way that changes in bladder function are assessed. This information will be used in the design and evaluation of a device, being developed in parallel, that assesses changes to the volume and flow of urine in order to determine changes in bladder function. In order to ensure development is optimal, the principal research objective is therefore to understand the needs of patients and healthcare practitioners (ranging from care home staff and GPs in primary care, to urologists in tertiary referral centres).

Detrusor underactivity (DUA) in men is responsible for LUTS in a significant minority, the symptoms being indistinguishable from those seen in BOO. The International Continence Society (ICS) defines DUA as 'a detrusor contraction of inadequate magnitude and/or duration to effect complete bladder emptying in the absence of urethral obstruction. Whilst a reduced maximum urinary flow rate (Qmax) is indicative of voiding dysfunction, flow studies cannot distinguish between DUA and BOO, which are the two principal causes of low flow rates. DUA is diagnosed from a pressure-flow study (PFS)and is characterized by a low-pressure, poorly sustained, or wave-like detrusor contraction with an associated poor flow rate. Overactive bladder (OAB) is the most common term currently used in clinical medicine to describe a complex of lower urinary tract symptoms (LUTS) with or without incontinence but most commonly consisting of urgency, frequency, nocturia, troublesome or incomplete emptying,and, occasionally, pain. With the exception of pain and incontinence, these symptoms are often found together; thus, the term LUTS has come to replace previous terms, such as urgency-frequency syndrome,urethral syndrome, and prostatism. Drug treatment is frequently used as the initial management approach for LUTS in older men.Among men who desire treatment, general practice prescribing data have shown that antimuscarinics are not often given to elderly men. There is theoretical concern that the inhibitory effect of antimuscarinics on detrusor contraction could aggravate voiding difficulties or cause urinary retention in patients with BOO. There are virtually no data evaluating the safety and efficacy of solifenacin treatment in men with DUA and OAB.

Women with symptoms of voiding dysfunction may be associated with detrusor underactivity (DU) or bladder outlet obstruction (BOO). The treatment strategies are different between DU and BOO. In general, urodynamic/videourodynamic studies are important for differential diagnosis. However, urodynamic/videourodynamic studies are invasive. The investigators are interested in whether there were specific symptoms or measurements that can be used for initial differential diagnosis between DU and BOO. Thus, the aim of this study was to elucidate the prevalence of DU and BOO in each age group and elucidate the clinical and urodynamic differences between the DU, BOO and non-DU/BOO groups.

Background and study aims: The prostate gland sits around the exit of the bladder in men. As men get older, the prostate grows, and this can narrow the exit from the bladder, so that there is restriction of flow. As a result, some men develop difficulty passing urine (voiding) as they age. For these men, prostate surgery can be helpful by removing the part of the prostate causing the narrowing, so that flow improves. However, for some men, almost identical symptoms of difficulty passing urine are due to underactive bladder. In other words, the bladder contraction is too weak, and is not effective at expelling the urine. This is a smaller group, but important, as these men may have no improvement after prostate surgery, while being exposed to risk of complications of surgery. Medical assessment of men with voiding problems typically involves discussing the symptoms, doing a physical examination of the prostate and measuring the urine flow rate. In many NHS hospitals, these are the only tests done before deciding whether to proceed to prostate surgery. In effect, voiding symptoms are presumed to be a result of prostate enlargement for these men, since it is the more common problem compared with bladder underactivity. However, this approach cannot identify which men actually have bladder underactivity as the cause of their voiding symptoms. So, in some hospitals an extra test is used, called urodynamics. Urodynamics is done to measure how much pressure the bladder generates when passing urine, because a high pressure shows the problem is obstruction, and a low pressure shows it is bladder weakness. Urodynamics involves gently putting a small tube into the bladder via the penis to measure the bladder pressure, and to fill the bladder with a sterile fluid (saline). Another small tube is gently placed into the rectum, via the anus, to measure abdominal pressures. Measuring abdominal pressure is necessary because any change in abdominal pressure can affect bladder pressure, and if the test did not allow for this it could give a misleading result. Urodynamics is safe, but some men find it uncomfortable or undignified, and a few develop urine infection afterwards. No studies have been conducted so far to tell us which of these two approaches to assessing men with voiding urinary problems is better overall. UPSTREAM consists of two phases: "UPSTREAM - Phase I" was a pragmatic, two-arm, multicentre, randomised controlled trial (RCT) to determine the clinical and cost-effectiveness of invasive urodynamics (UDS) for the diagnosis and management of bladder outlet obstruction in men. Men from 26 urology departments of NHS Hospitals in England who had bothersome lower urinary tract symptoms (LUTS) and were seeking further treatment, which may have included surgery, were randomised to one of two study arms; 'Routine Care' (as per the NICE diagnostic pathway), or routine care plus UDS ('Urodynamics'), which is currently optional. The design was utilised to establish noninferiority in symptom severity (International Prostate Symptom Score [IPSS]) 18-months post-randomisation. The primary outcome was IPSS at 18-months post-randomisation, and a key secondary outcome was the influence of UDS on rates of bladder outlet surgery. The RCT started 01 April 2014 and ended 30 September 2018. In 2018, we were awarded an extension to conduct a further (long term) follow up of UPSTREAM participants, five years post-randomisation; "UPSTREAM - Phase II". We aim to identify: the symptom outcomes of treatment; definitive surgery rates in the two study arms; and the long-term impact of LUTS and its therapy. The focus will continue to be on effectiveness and patient outcomes as per the original commissioning brief. "UPSTREAM - Phase II" started 01 July 2019 and has a planned end date of 30 June 2022.

Prevalence rates of bladder outlet obstruction (BOO) and detrusor underactivity (DU) and their related clinical and urodynamic findings in women with ≥ pelvic organ prolapse quantification stage II cystocele are important for clinical consultation. Thus, the aim of this study was to elucidate the above findings and between-group associations.

As a part of the urodynamic studies, urinary catheterization is inserted to measure residual urine, however, it has shown to be an invasive procedure, cause urinary tract infection, and traumatic experience. Bladder scan has been introduced as an alternative and non-invasive method to measure urine residual in the bladder.

Women with cystocele may be associated with detrusor underactivity (DU) or bladder outlet obstruction (BOO). However, the impact of cystocele repair on the rates of DU and BOO remained obscure. Thus, the aim of this study was to elucidate the prevalence of DU and BOO in each age group and elucidate the impact of cystocele repair on the rates of DU and BOO.

Detrusor underactivity (DU) is a known disease of the muscles of the urinary bladder that defined as a weak contraction of the muscle resulting in a failure to achieve complete bladder emptying. Recently, DU as a cause of Lower Urinary Tract Symptoms in both men and women has been increasingly gaining attention. There is a major issue in differentiation of underactive bladder symptoms and other causes of lower urinary tract symptoms such as detrusor hyperactivity and impaired contractility (DHIC), hypersensitive bladder (HSB), detrusor overactivity (DO), bladder outlet obstruction (BOO) and Dysfunctional Voiding (DV). Urodynamics (UDS) is the standard diagnostic tool, it includes invasive recording of the pressure that is produced when the bladder muscle contracts via pressure sensors introduced in the urinary bladder through special types of urethral catheters. This study aims to determine the prevalence of DU along with its symptomatic and urodynamics (UDS) characteristics of DU in Jordanian population through a retrospective chart review.
