Both sorafenib and interleukin-27 (IL-27) are antineoplastic drugs. This study aimed to investigate the synergistic effect of these two drugs on bladder cancer cells. HTB-9 and T24 cells were stimulated with IL-27 (50 ng/mL), sorafenib (2 μM) or the synergistic action of these two drugs. The cells without treatment acted as control. Cell proliferation, apoptosis and invasion were measured by bromodeoxyuridine assay, flow cytometry and modified Boyden chamber, respectively. Simultaneously, both modified Boyden chamber and scratch assay were used to assess cell migration...

BACKGROUND: Calcium electroporation is a new experimental anti-cancer treatment where calcium is internalized into cells by application of short, high voltage pulses. Calcium electroporation has been shown to induce tumor necrosis associated with ATP depletion while the effect on normal fibroblasts was limited when investigated in a 3D in vitro spheroid model. We aimed to investigate the effect of calcium electroporation in combination with metformin, a drug that affects intracellular ATP level...

Cisplatin (CP) is a potent and widely used chemotherapeutic agent. However, the clinical benefits of CP are compromised because it elicits nephrotoxicity and ototoxicity. In this study, we investigated the nephroprotective effects of the phytochemical genipin (GP) isolated from the gardenia (Gardenia jasminoides) fruit, using a murine model of CP-induced nephropathy. GP pretreatment attenuated the CP-induced renal tissue injury by diminishing the serum blood urea nitrogen, creatinine, and cystatin C levels, as well as those of kidney injury molecule-1...

White light endoscopy is widely used for diagnostic imaging of the interior of organs and body cavities, but the inability to correlate individual 2D images with 3D organ morphology limits its utility for quantitative or longitudinal studies of disease physiology or cancer surveillance. As a result, most endoscopy videos, which carry enormous data potential, are used only for real-time guidance and are discarded after collection. We present a computational method to reconstruct and visualize a 3D model of organs from an endoscopic video that captures the shape and surface appearance of the organ...

REVIEW
Yogesh Kumar Sarin, Virender Sekhon
The surgical techniques for management of bladder exstrophy epispadias complex have evolved from staged reconstruction, complete primary repair to radical mobilization. Post-operative complications add to the multiplicity of surgical procedures at each step. The end results are variable with many achieving continence rates of 85-89% only after bladder augmentation and clean intermittent catheterization. The situation is further complicated in resource-poor settings, where illiteracy and poverty are the driving factors for choosing a single operative procedure for creation of low pressure reservoir aiming at upper tract preservation and good primary continence...

BACKGROUND: If untreated, paediatric neurogenic bladder can cause renal failure and urinary incontinence. It is usually caused by neural tube defects such as myelomeningocele. Children with a neurogenic bladder should be monitored from birth and management should aim to preserve renal function and achieve social continence. This article outlines the management options appropriate for these children in resource-poor settings. ASSESSMENT: In most low- and middle-income countries, a general lack of awareness of the neurological effects on the urinary tract results in late presentation, usually with urological complications even when spina bifida is diagnosed early...

BACKGROUND: In patients with congenital bladder anomalies, bladder augmentation is used as a last resort to reduce intravesical pressure, but concerns about malignant transformation in augmented patients were first raised in the 1980s. The best evidence to date indicates that augmentation does not appear to increase the risk of bladder cancer in spina bifida patients. To date, oncologic outcomes from patients with spina bifida with and without augmentation have only been available in small case reports...

OBJECTIVE: To evaluate the outcomes of patients who underwent cutaneous vesicostomy for management of neuropathic bladder secondary to spina bifida. We hypothesize that vesicostomy, in select patients, is beneficial to prevent upper urinary tract deterioration (UTD), reduce febrile urinary tract infections (UTIs), and preserve renal function. STUDY DESIGN: We performed a retrospective chart review on patients with spina bifida who underwent cutaneous vesicostomy at our institution between 2000 and 2016...

OBJECTIVES: The aim of this study was to investigate surgical practice patterns of American urologists treating refractory overactive bladder (OAB) over the past decade. Refractory OAB remains a management challenge to urologists. When multiple medical therapies have failed, treatment options may include sacral neuromodulation (SNM) or surgery such as augmentation cystoplasty (AC). METHODS: Data on SNM and AC performed between 2003 and 2012 by certifying and recertifying urologists were obtained in the form of annualized case logs from the American Board of Urology (ABU)...

BACKGROUND: Due to the multilineage differentiation ability and paracrine role of adipose-derived stem cells (ASCs) for bladder defect repair, various scaffolds have been applied in combination with ASCs to promote bladder regeneration and restore bladder function. However, the low survival rate of ASCs and the difficulty of promoting bladder functional recovery are still unsolved. To explore these problems, we investigated the feasibility of a novel scaffold seeded with ASCs in a rat model of bladder augmentation...

Lower urinary tract reflexes are mediated by peripheral afferents from the bladder (primarily in the pelvic nerve) and the urethra (in the pudendal and pelvic nerves) to maintain continence or initiate micturition. If fluid enters the urethra at low bladder volumes, reflexes relax the bladder and evoke external urethral sphincter (EUS) contraction (guarding reflex) to maintain continence. Conversely, urethral flow at high bladder volumes, excites the bladder (micturition reflex) and relaxes the EUS (augmenting reflex)...

REVIEW
Charlotte Q Wu, Israel Franco
Vesicoureteral reflux (VUR) is a significant risk factor for pyelonephritis and renal scarring. VUR can occur through a defective ureterovesical junction (UVJ) or an overwhelmed normal UVJ mechanism such as in bladder dysfunction of congenital, acquired, or behavioral etiology. There are numerous causes for the development of a neurogenic bladder from spinal dysraphisms to spinal cord trauma and even centrally based abnormalities in children with apparently normal motor function (inappropriately termed nonneurogenic neurogenic bladder)...
