Augmentation cystoplasty is a procedure to increase the anatomical as well as functional capacity of the urinary bladder using a segment of bowel or ureter. Upto half of these patients develop complications but most of them are minor and managed easily. Urolithiasis, especially bladder calculi are seen in upto half of the cases and are removed endoscopically or by open approach. Hysterectomy is an uncommon procedure in patients with augmentation cystoplasty and is complicated by the altered anatomy of the pelvis...

The stomach is the preferred augmentation option for a contracted bladder in a patient with renal failure. A 49-year-old female presented with right solitary functioning kidney with tuberculous lower ureteric stricture and contracted bladder. Her creatinine was 2.8 mg%. By laparoscopic approach, right gastroepiploic artery based gastric flap was isolated using staplers and used for augmentation and ureteric replacement. At 6-month follow-up, her creatinine was 1.9 mg%, and bladder capacity was 250 ml. She had mild hematuria, which settled with proton pump inhibitors...

Although recent studies have demonstrated the anti-tumor effects of garlic extract (GE), the exact molecular mechanism is still unclear. In this study, we investigated the molecular mechanism associated with the inhibitory action of GE against bladder cancer EJ cell responses. Treatment with GE significantly inhibited proliferation of EJ cells dose-dependently through G2/M-phase cell cycle arrest. This G2/M-phase cell cycle arrest by GE was due to the activation of ATM and CHK2, which appears to inhibit phosphorylation of Cdc25C (Ser216) and Cdc2 (Thr14/Tyr15), this in turn was accompanied by down-regulation of cyclin B1 and up-regulation of p21WAF1...

INTRODUCTION: The surgical correction of bladder exstrophy remains challenging. In our institution, the repair has evolved from a staged repair to one-stage reconstruction. The one-stage reconstruction includes; bladder closure, Cantwell-Ransley neourethroplasty and abdominoplasty using groin flaps, without the need of pelvic ostheotomies. Repair of urinary continence (UC) and vesicoureteral reflux (VUR) is done after development of the infant. OBJECTIVE: To present our experience of our modified one-stage reconstruction of bladder exstrophy in male patients...

We present a rare case of indirect vesicovaginal fistula (VVF) in a patient with small capacity bladder. The fistula was between abdominal pseudocyst (APC) arising from bladder and vagina - and hence, an indirect VVF. A 35-year-old female had a history of emergency obstetric hysterectomy with iatrogenic bladder injury. Postoperatively, the patient developed VVF and large APC. Patient's micturating cystourethrogram was suggestive of small capacity bladder with bilateral Grade IV vesicoureteral reflux with a well-defined APC arising from superior surface of bladder to L4-L5 lumbar vertebrae...

BACKGROUND: The repair of urinary bladder tissue is a necessity for tissue loss due to cancer, trauma, or congenital abnormalities. Use of intestinal tissue is still the gold standard in the urological clinic, which leads to new problems and dysfunctions like mucus production, stone formation, and finally malignancies. Therefore, the use of artificial, biologically derived materials is a promising step towards the augmentation of this specialised tissue. The aim of this study was to investigate potential bladder wall repair by two collagen scaffold prototypes, OptiMaix 2D and 3D, naïve and seeded with autologous vesical cells, as potential bladder wall substitute material in a large animal model...

A 28-year-old female with a 1-year history of ketamine abuse developed ketamine-associated urinary symptoms that were refractory to conservative treatment after the complete cessation of ketamine use. Smooth voiding with increased bladder capacity and minimal postvoid residual urine volume were achieved by performing an augmentation enterocystoplasty. An uneventful pregnancy with the vaginal delivery of a healthy baby occurred postoperatively.

INTRODUCTION: Bladder augmentation with demucosalized ileal flap is a promising alternative approach for mucus free bladder augmentation; however, the contraction of the flap is still a major concern. It has been hypothesized that mucosectomy causes ischemic damage, but no direct histological evidence has been found and attention is now focused on the urothelium cover to prevent the exposure of the denuded surface to urine or the use of balloons to keep the flaps distended. OBJECTIVE: Our aim was to study the effect of mucosectomy on the microcirculation of ileal flaps during reverse clam ileocystoplasty using direct intraoperative imaging of the ileum...

Joana Lopes, Andy Robb, Liam McCarthy
BACKGROUND/PURPOSE: Reconstruction of microbladders is a difficult surgical challenge: How can a neobladder be recreated when >90% of the new bladder is augmented patch, and how can a Mitrofanoff conduit be anastomosed when the native bladder is so tiny? This series describes microbladders secondary to anuria and/or diversion that required augmentation. This was done using a de-tubularized ileal segment, and because of the small size of the native bladder, Mitrofanoff anastomosis was performed to the bowel patch (using a novel "Keel Procedure")...

PURPOSE: The spectrum of male urethral duplication is heterogeneous and it includes the Y-duplication. The malformation is rare and there is only a few case series reported in the literature. The management of Y-forms remains challenging for the surgeon and the long-term follow-up is still scarcely investigated. We report our 40-year experience in the management of patients with Y-duplication. MATERIALS AND METHODS: We conducted a restrospective analysis collecting information of patients with urethral Y-duplication treated at our department from April 1975 to April 2015...

EDITORIAL
Pierre A Guertin
Relatively soon after their accident, patients suffering a spinal cord injury (SCI) begin generally experiencing the development of significant, often life-threatening secondary complications. Many of which are associated with chronic physical inactivity-related immune function problems and increasing susceptibility to infection that repeatedly requires intensive care treatment. Therapies capable of repairing the spinal cord or restoring ambulation would normally prevent many of these problems but, as of now, there is no cure for SCI...
