INTRODUCTION: Life expectancy for people with spinal cord injury has shown a marked increase due to modern advances in treatment methods and in neuro-urology. However, since life expectancy of people with paralysis increases, the risk of developing of urinary bladder cancer is gaining importance. MATERIALS AND METHODS: Single-centre retrospective evaluation of patient data with spinal cord injuries and proven urinary bladder cancer and summary of the literature...

INTRODUCTION: Laminectomy is the traditional approach for posterior exposure of the spinal canal for tumor resection. Another technique is split laminotomy, which entails the division and retraction of the spinous processes and laminae to access the thecal sac. This technique has been employed for small-segment exposures, but not extensively explored for long-segment exposures. CASE: A 2-month-old male presented with progressive right-leg plegia. MRI of the spine revealed a large, intramedullary spinal-cord lipoma extending from C6 to L5...

Male lower urinary tract symptoms (LUTS) due to bladder outlet obstruction are characterized by abnormal smooth muscle contractions in the lower urinary tract. Alpha1-adrenoceptor antagonists may induce smooth muscle relaxation in the outflow region and represent the current goldstandard of medical treatment. However, results may be unsatisfactory or inadequate. Apart from α1-adrenoceptor agonists, smooth muscle contraction in the outflow region may be induced by thromboxane A2 (TXA2), endothelins, or muscarinic receptor agonists...

Neurogenic detrusor overactivity (NDO) is among the most challenging complications of spinal cord injury (SCI). A recent report by us demonstrated an improvement in NDO in SCI rats following chronic systemic treatment with the purine nucleoside inosine. The objective of this study was to investigate the mechanism of action of inosine underlying improvement of NDO. Male Sprague-Dawley rats underwent complete spinal cord transection at T8. Inosine (1 mM) delivered intravesically to SCI rats during conscious cystometry significantly decreased the frequency of spontaneous non-voiding contractions...

Urinary incontinence, or the loss of bladder control, is a debilitating condition affecting millions worldwide, which significantly reduces quality of life. Neuromodulation of lower urinary tract nerves can be used to treat sensations of urgency in many subjects, including those with Spinal Cord Injury (SCI). Event driven, or conditional stimulation has been investigated as a possible improvement to the state-of-the-art open-loop stimulation systems available today. However, this requires a robust, adaptive, and noise-tolerant method of classifying bladder function from real-time bladder pressure measurements...

Rodent models for the study of neurogenic bladder dysfunction after spinal cord injury (SCI) are difficult to standardize, particularly when evaluating the specific contribution of the SCI to end-organ function. The purpose of this study was to evaluate the degree of bladder dysfunction associated with a highly reproducible, contusion-induced SCI in female rats. An infinite horizon impactor was used to create a contusion SCI with a magnitude of either 100 or 150 kDyne at the T8/T9 thoracic region of female Sprague-Dawley rats...

Bladder and bowel dysfunction (BBD) describes a spectrum of lower urinary symptoms (LUTS) accompanied by fecal elimination issues that manifest primarily by constipation and/or encopresis. This increasingly common entity is a potential cause of significant physical and psychosocial burden for children and families. BBD is commonly associated with vesicoureteral reflux (VUR) and recurrent urinary tract infections (UTIs), which at its extreme may lead to renal scarring and kidney failure. Additionally, BBD is frequently seen in children diagnosed with behavioural and neuropsychiatric disorders such as attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD)...

BACKGROUND Fecal incontinence and constipation are common gastrointestinal complaints, but rarely occur concurrently. Management of these seemingly paradoxical processes is challenging, as treatment of one symptom may exacerbate the other. CASE REPORT A 51-year-old female with lifelong neurogenic bladder secondary to spina bifida occulta presented with progressive symptoms of daily urge fecal incontinence as well as hard bowel movements associated with straining and a sensation of incomplete evacuation requiring manual disimpaction...

AIM: Transurethral resection of prostate (TURP) is considered a gold standard surgical procedure. The management of benign prostatic hyperplasia (BPH) has undergone tremendous change in recent years and shifted from open to minimal invasive procedure. With the advancement in technology and skills of surgeons, lasers have been used more liberally, particularly holmium laser. Holmium laser enucleation of prostate (HoLEP) is seen as close rival of TURP. The objective if this study is to observe long- and short-term outcomes of transurethral resection and holmium laser enucleation in the prostate of more than 60 g...

INTRODUCTION: The proactive management of children with myelomeningocele (MMC) has contributed to decreasing their progression to end-stage renal disease, thanks to early urological evaluation and timing implementation of treatments. OBJECTIVE: To demonstrate that early urological evaluation of the urinary tract in MMC shows functional alterations in most cases, and that it requires medical intervention, even when in some cases the complementary imaging studies do not show any abnormalities...

INTRODUCTION: Children with recurrent urinary tract infections (rUTI) often show no identifiable cause of their infections. Neutrophil gelatinase-associated lipocalin (NGAL) is known to be upregulated within the uroepithelium and kidney of patients with UTI and exhibits a localized bacteriostatic effect through iron chelation. We hypothesize that some patients with rUTI without an identifiable cause of their recurrent infections have locally deficient NGAL production. We therefore explored whether a lack of NGAL production may be a factor in the pathogenesis of rUTI...

BACKGROUND: Neurogenic detrusor overactivity (NDO) often results in decreased bladder capacity, urinary incontinence, and vesico-ureteral reflux. NDO can trigger autonomic dysreflexia and can impair quality of life. Electrical stimulation of the genital nerves (GNS) acutely inhibits reflex bladder contractions and can increase bladder capacity. Quantifying the effect of GNS on bladder capacity and determining what study factors and subject factors influence bladder capacity improvements will inform the design of clinical GNS interventions...

BACKGROUND: Neurogenic detrusor overactivity after spinal cord injury (SCI) causes urinary incontinence and reduces bladder capacity. Surface electrical genital nerve stimulation (GNS) acutely inhibits reflex bladder contractions. The stimulation amplitude selected for GNS is typically twice the amplitude that is required to evoke the pudendal-anal reflex. There is concern about the ability of persons with sensation to comfortably tolerate effective levels of GNS. The objective of this work is to determine if persons with incomplete SCI are able to tolerate acute GNS for bladder inhibition...
