The Role of microRNAs in Organ Remodeling in Lower Urinary Tract Dysfunction

Prostatic HyperplasiaUrinary Bladder Neck Obstruction2 more

Urgency, frequency and incomplete emptying are the key symptoms of lower urinary tract dysfunction, including bladder pain syndrome/interstitial cystitis, and overactive bladder syndrome. Lower urinary tract dysfunction is associated with cellular stress, leading to changes in gene expression and consequent organ remodeling. MicroRNAs are small regulatory molecules, affecting protein synthesis. They are quickly winning recognition as potential therapeutic agents. The investigators will perform a comparative study of mRNAs changed in lower urinary tract dysfunction and address the role of differentially expressed miRNAs in regulation of the genes, important for bladder function. The experimental approach, combining the analysis of human biopsy material with the in vitro cell-based models, will allow the investigators to elucidate the effects of miRNAs on the expression of receptors, contractile proteins and tight junction proteins. Once the disease-induced miRNAs have been characterised and their target genes validated, it will be possible to influence their expression levels thus counter-acting their effects. The investigators' work addresses fundamental mechanisms of signal transduction in urothelium and smooth muscle during cellular stress caused by inflammation or bladder outlet obstruction, and its regulation in the diseased state. The investigators' findings will further the knowledge of the molecular mechanisms of lower urinary tract dysfunction and have implications for diagnosis and treatment. Additionally, they have relevance for other clinical conditions, where miRNAs are implicated.

Bladder Neck ObstructionBladder Outlet Obstruction2 more

Autologous adipose-derived regenerative cells (ADRC) will be extracted from lipoaspirate by enzymatic digestion from a portion of the fat harvested from the patient's front abdominal wall. Transurethral bladder neck resection followed by the injection of ADRCs suspension will be performed. This is a single arm study with no control. All patients receive cell therapy.

Prevalence of Detrusor Underactivity and Bladder Outlet Obstruction in Female Without Cystocele...

Voiding Disorders

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.

Diagnosis of Bladder Outlet Obstruction Using Dynamic Urine Vibration "Holter" in Comparison to...

Bladder Outlet Obstruction

Current gold standard of bladder outlet diagnosis is pressure flow study. This study is invasive time consuming and requires expensive and complex set-up. In this study the investigators plan to evaluate an alternative technology that presumably is able to diagnose bladder outlet obstruction using a Dynamic Urine Vibration "Holter" based on a Urine Flow Vibration Analysis technology. The acoustic vibration sensor is a small device that records the vibration due to urine flow. The patient attaches the sensor to the penis using a disposable sensor patch for the duration of approximately one minute during one urination. The analysis is performed off-line and the results are compared to the results of a standard pressure flow study. The innovative technology for the diagnosis of bladder outlet obstruction is noninvasive, rapid and does not involve complex setup.

Comparison Between Invasive Pressure Flow Study and Non-invasive Penile Cuff Test

Bladder Outlet ObstructionPressure Flow Study

To provide evidence of promising tests to noninvasively diagnose bladder outlet obstruction (BOO) in men with benign prostatic hyperplasia. Penile cuff test provides a means of obtaining a urodynamic diagnosis with a high level of accuracy without the morbidity and expense of invasive Pressure flow study. Penile cuff test may be particularly useful in the counseling of patients prior to benign prostatic hyperplasia operation. Patients diagnosed as obstructed following a penile cuff test can be reassured that surgery has a high chance of resulting in symptomatic benefit

Detrusor Underactivity and Bladder Outlet Obstruction in Women With Cystocele

Cystocele

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.

BOO and DU and Their Clinical and Urodynamic Findings in Women With ≥Stage II Cystocele

Bladder Outlet Obstruction and Detrusor Underactivity in Women With Severe Cystocele

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.

Detrusor UnderactivityBladder Outlet Obstruction

Women with symptoms of voiding dysfunction may be associated with detrusor underactivity or bladder outlet obstruction. However, the prevalence of detrusor underactivity and bladder outlet obstruction remained obscure. Thus, the aim of this study was to elucidate the prevalence of detrusor underactivity and bladder outlet obstruction in women with and without symptoms of voiding dysfunction.

Urodynamics and Clinical Factors That Are Associated With Bladder Over-sensitivity

Overactive Bladder SyndromeBladder Outlet Obstruction3 more

Urodynamic examination evaluates storage and empting phases of the urinary bladder. It enables the clinician to correlate physiologic findings to patients' complains. The data gathered during the examination divided to storage and empting. During the storage phase, bladder sensation is measured while the bladder is filled with sterile water. During years of practice, we noticed that early sensation (bladder over-sensitivity) is occasionally associated with bladder outlet obstruction (as demonstrated in the emptying phase of the examination.
