Huiyi H Chang, Jih-Chao Yeh, Ronaldo M Ichiyama, Larissa V Rodriguez, Leif A Havton
Spinal cord epidural stimulation (SCS) represents a form of neuromodulation for the management of spasticity and pain. This technology has recently emerged as a new approach for potentially augmenting locomotion and voiding function in humans and rodents after spinal cord injury. However, the effect of SCS on micturition has not been studied extensively. Here, SCS was first applied as a direct stimulus onto individual segmental levels of the lumbar spinal cord in rats to map evoked external urethral sphincter (EUS) electromyography activity and SCS-induced voiding contractions...

Lower urinary tract abnormalities are difficult to resolve in pediatric kidney transplant patients. Measure of residual urine, voiding cystourethrography, retrograde urethrography, cystometry, electromyography of urethral external sphincter muscle, urethrometry, and uroflowmetry are the primary methods for evaluation of lower urinary tract abnormalities. Endoscopic resection or ablation of urethral valves is required in children with posterior urethral valve to treat obstruction, but bladder function does not always recover and may deteriorate to end-stage renal failure even after the obstruction is released...

OBJECTIVE: To assess the effectiveness of Intradetrusor injections of botulinum toxin type A (IDBTX-A) in children with spina bifida. PATIENTS AND METHODS: All patients aged under 16 year-old who underwent IDBTX-A between 2002 and 2016 at six institutions were included in a retrospective study. Our primary endpoint was the success rate of IDBTX-A defined as both clinical improvement (no incontinence episodes between clean-intermittent catheterization (CIC), absence of urgency, less than 8 CIC per day)) and urodynamic improvement (resolution of derusor overactivity, normal bladder compliance for age) lasting ≥ 12 weeks...

Enhanced spontaneous contractions are associated with overactive bladder. Elevated levels of reactive oxygen species might contribute to enhanced spontaneous contractions. We investigated the regulation of spontaneous contractions and the effects of hydrogen peroxide (H2 O2 ) in intact rat bladder strips. The spontaneous contractions were measured using a tissue bath system. The vehicle or the specific activators/blockers were applied and followed by the application of 0.003 g% H2 O2 . The basal tension, amplitude, and frequency of spontaneous contractions were quantified...

AIMS: Neurogenic bladders (NGB) with detrusor leak point pressures >40 cm H2 O (dLPP > 40) have been associated with deterioration of renal function in children with myelomeningocele. For these children, careful pressure management preserves renal function. However, similar evidence is lacking in adult congenital urology (ACU) patients with NGB. We describe renal functional outcomes of non-surgical management of adults with dLPP > 40 or premicturition detrusor pressure (PMDP) >40 cm H2 O, consisting of close follow-up with urodynamic studies (UDS) and renal ultrasound (RUS), paired with adjustments to clean intermittent catheterization (CIC) frequency, anticholinergics, and addition of onabotulinumtoxinA toxin (BTX) injection...

INTRODUCTION: Intradetrusor injections of onabotulinumtoxinA (BoNTA) is well-established as treatment for patients with neurogenic bladders. Urodynamics (UDS) are used at regular intervals during followup to monitor intravesical pressure. With regards to the discomfort and risks associated with UDS, our objective was to assess if UDS done at regular intervals in the followup of neurogenic bladders treated with BoNTA had an impact on management. METHODS: We retrospectively analyzed the medical records of adult patients with neurologic disorders treated with BoNTA for either detrusor overactivity or low bladder compliance at the Institut de Réadaptation en Déficience Physique de Québec (IRDPQ)...

INTRODUCTION: Debris within the bladder is commonly seen on ultrasound. The etiology of bladder debris is varied and the likelihood that urinary debris represents positive urine culture is under investigation. We hypothesize that bladder debris will increase the likelihood that a urine culture is positive compared to those without bladder debris. METHODS: We performed a retrospective review on children aged 0-17 years who had a voiding cystourethrogram with a catheterized urinalysis or urine culture, and who also had a renal and bladder ultrasound up to 1 week prior, the day of, or up to 2 days after their urine studies...

The urinary bladder is a complex organ with the primary functions of storing urine under low and stable pressure and micturition. Many clinical conditions can cause poor bladder compliance, reduced capacity, and incontinence, requiring bladder augmentation or use of regenerative techniques and scaffolds. To replicate an organ that is under frequent mechanical loading and unloading, special attention towards fulfilling its biomechanical requirements is necessary. Several biological and synthetic scaffolds are available, with various characteristics that qualify them for use in bladder regeneration in vitro and in vivo, including in the treatment of clinical conditions...

Context • Benign prostatic hyperplasia (BPH) produces lower urinary tract symptoms (LUTS) that diminish quality of life. Conventional treatments are often accompanied by adverse side effects. By contrast, consumers of phytochemicals-based dietary supplements often report a reduction in symptoms without side effects. The field needs studies that quantify the strength and character of perceived benefits. Objectives • The study intended to quantify the character and strength of perceived improvements in LUTS in men, after the consumption of a prostate health supplement...

Genetic abnormalities and epigenetic alterations both play vital role in initiation as well as progression of cancer. Whereas genetic mutations cannot be reversed, epigenetic alterations such as DNA methylation can be reversed by the application of DNA methyltransferase inhibitor decitabine. Epigenetic silencing of RASSF1A and involvement of hippo pathway both have been shown to involve in chemo-resistance. Purpose of this study was to observe the effect of combination treatment of decitabine with cisplatin or doxorubicin on bladder cancer cells involving hippo pathway through RASSF1A...

A variety of tissue engineering techniques utilizing different cells and biomaterials are currently being explored to construct urinary bladder walls de novo, but so far no approach is clearly superior. The aim of this study was to determine whether mesenchymal stem cells (MSCs) isolated from different sources, (bone marrow [BM-MSCs] and adipose tissue [ADSCs]), differ in their potential to regenerate smooth muscles in tissue-engineered urinary bladders and to determine an optimal number of MSCs for urinary bladder smooth muscle regeneration...

BACKGROUND: Guidelines for bladder augmentation (BA) in kidney transplant (KT) recipients are not well-defined. In our center, simultaneous BA with KT (BA-KT) is performed. We assessed transplantation outcomes of this unique extensive procedure. METHODS: A case-control single center retrospective study. Transplantation outcomes were compared with those of KT recipients who did not need BA. RESULTS: Compared to 22 patients who underwent KT only, for 9 who underwent BA-KT, surgical complications and the need for revision in the early posttransplantation period were similar; early graft function was better: estimated glomerular filtration rate (eGFR): 96...

BACKGROUND: Urinary bladder dysfunction in the form of acontractile/hypocontractile bladder is very common after spinal cord injury and it may lead to recurrent urinary tract infection (UTI), stones formation, and deteriorating renal function. Conventionally, these patients evacuate their bladders by life-long clean intermittent catheterization (CIC) or an indwelling catheter (IC). For these patients, another option is to use innervated skeletal muscle wrap around the bladder to augment detrusor function and voluntary evacuation of bladder...

Sacral neuromodulation (SNM) offers promise in the therapy of many pelvic floor disorders. This innovative treatment has slowly gained popularity. A review of recent literature is presented in relation to its efficacy and complications in various pelvic floor conditions: overactive bladder and urge urinary incontinence, chronic urinary retention, painful bladder syndrome, pelvic pain and double incontinence. It is a minimally invasive, completely reversible safe procedure with good long-term outcomes. However, the treatment is costly, the revision rate is high and patients require life-long follow-up...
