AIMS: Abnormal intravesical pressure results in a series of pathological changes. We investigated the effects of hydrostatic pressure and muscarinic receptors on the release of inflammatory cytokines in rat and human bladder smooth muscle cells (HBSMCs). METHODS: Animal model of bladder outlet obstruction was induced by urethra ligation. HBSMCs were subjected to elevated hydrostatic pressure and/or acetylcholine (Ach). Macrophage infiltration in the bladder wall was determined by immunohistochemical staining...

INTRODUCTION: The Kropp and Salle procedures have shown good short-term outcomes for managing neuropathic urinary incontinence. However, few studies have assessed their long-term results. OBJECTIVE: This study aimed to evaluate the long-term outcomes of Kropp and Salle procedures, including: dryness, secondary interventions for incontinence or complications, upper urinary tract changes, and use of urethral catheterizations. STUDY DESIGN: Consecutive patients undergoing Kropp and Salle procedures at the present institution (1983-2012) were retrospectively reviewed...

PURPOSE OF REVIEW: There are concerns that patients with congenital bladder anomalies (CBA) may be at higher risk for developing bladder malignancy later in life. To date there is no consensus on how to monitor these patients to prevent this devastating malignancy. We will review the current understanding of bladder malignancy in patients with CBA and the status of surveillance tests. RECENT FINDINGS: Initial reports observed that augmentation cystoplasty in CBA may be an independent risk factor for bladder malignancy...

Bladder drug delivery via catheter instillation is a widely used treatment for recurrence of superficial bladder cancer. Intravesical instillation of liposomal botulinum toxin has recently shown promise in the treatment of overactive bladder and interstitial cystitis/bladder pain syndrome, and studies of liposomal tacrolimus instillations show promise in the treatment of hemorrhagic cystitis. Liposomes are lipid vesicles composed of phospholipid bilayers surrounding an aqueous core that can encapsulate hydrophilic and hydrophobic drug molecules to be delivered to cells via endocytosis...

REVIEW
Jia-Fong Jhang, Hann-Chorng Kuo
The use of onabotulinumtoxinA (BoNT-A) for the treatment of lower urinary tract diseases (LUTD) has increased markedly in recent years. The indications for BoNT-A treatment of LUTD now include neurogenic or idiopathic detrusor overactivity, interstitial cystitis/bladder pain syndrome and voiding dysfunction. The mechanisms of BoNT-A action on LUTDs affect many different aspects. Traditionally, the effects of BoNT-A were believed to be attributable to inhibition of acetylcholine release from the presynaptic efferent nerves at the neuromuscular junctions in the detrusor or urethral sphincter...

Urinary diversion is a surgical technique to redirect the stream of urine, most often after cystectomy. Cystectomy may be performed both for benign and for malignant conditions. Bladder cancer is the most common indication for cystectomy, and most patients who undergo radical cystectomy and urinary diversion have muscle-invasive or high-risk non-muscle-invasive bladder cancer. There are two major surgical approaches for urinary diversions performed after radical cystectomy: continent and incontinent diversions...

Terry W Hensle, Elizabeth A Reiley, Mina M Fam, Christina P Carpenter
BACKGROUND: Studies show that enterocystoplasty has a negative effect on bone mineral density (BMD). The aim of this study was to investigate the long-term impact of enterocystoplasty on BMD. We used dual energy x-ray absorptiometry (DEXA) scans to determine BMD and identify patients with osteopenia and osteoporosis who are at potential long-term risk for fracture. MATERIALS AND METHODS: We reviewed our database of >200 individuals, who had undergone enterocystoplasty or continent diversion for both neurogenic and non-neurogenic reasons during childhood...

REVIEW
Mya E Levy, Sean P Elliott
Cutaneous catheterizable channels allow for continent bladder emptying when an alternate route is desired. The goals of channel creation in the neurogenic bladder population are successful urine elimination, renal preservation, continence and lastly cosmesis. In addition to a particular surgeon's comfort and experience with a given procedure, individual patient factors such as medical comorbidities, anatomic factors, and occupational function should be central to the selection of a surgical approach. An ideal channel is one that is short, straight, and well supported by associated blood supply and surrounding adventitia, so as to minimize difficulty with catheterization...

BACKGROUND: We desire to review our experience with bladder augmentation in spina bifida patients followed in a transitional and adult urologic practice. This paper will specifically focus on three major complications: bladder calculi, the most frequent complication found following bladder augmentation, perforation of the augmentation, its most lethal complication and finally we will address loss of renal function as a direct result of our surgical reconstructive procedures. METHODS: We reviewed a prospective data base maintained on patients with spina bifida followed in our transitional and adult urology clinic from 1986 to date...
