bladder augmentation

Sajni I Khemchandani
INTRODUCTION: Classic bladder exstrophy (BE) is a rare malformation of the genito-urinary tract affecting 1:50,000 to 1:100,000 live births. The surgical reconstruction of the BE-epispadias complex is challenging for the most experienced pediatric urologists, surgeons, and orthopedists. PURPOSE: To assess the success of staged reconstruction of the BE and long-term effects on the upper urinary tract, renal function, and continence. MATERIALS AND METHODS: This is retrospective study; between 1994 and 2013, 30 patients with BE have undergone stage 1 repair at the institute...

OBJECTIVE Therapeutic options for brain metastases (BMs) that recur after stereotactic radiosurgery (SRS) remain limited. METHODS The authors provide the collective experience of 4 institutions where treatment of BMs that recurred after SRS was performed with stereotactic laser ablation (SLA). RESULTS Twenty-six BMs (in 23 patients) that recurred after SRS were treated with SLA (2 patients each underwent 2 SLAs for separate lesions, and a third underwent 2 serial SLAs for discrete BMs). Histological findings in the BMs treated included the following: breast (n = 6); lung (n = 6); melanoma (n = 5); colon (n = 2); ovarian (n = 1); bladder (n = 1); esophageal (n = 1); and sarcoma (n = 1)...

INTRODUCTION: Bladder augmentation is a common surgical intervention for neuropathic bladder dysfunction, and has conventionally been an open procedure. We present a robotic ileocystoplasty to demonstrate the feasibility of an entirely intracorporeal approach in a pediatric patient. METHODS: The patient was a 6 year old (18.5 kg) boy with a neurogenic bladder secondary to lumbar myelomeningocele. Urodynamics revealed a small capacity and poorly compliant bladder and he was incontinent between frequent catheterizations...

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...

INTRODUCTION: Vesicovaginal fistula (VVF) is the most common type of urogenital fistula. Gynecologic surgery is the most common cause associated with it. Laparoscopic approach for VVF repair gives the benefit of minimally invasive surgery with principles similar to open transabdominal approach. MATERIALS AND METHODS: We retrospectively reviewed data of 13 patients who underwent laparoscopic vesicovaginal repair at our department from December 2012 to December 2014...

Our previous work confirmed that the bladder cancer-specific oncolytic adenovirus Ad/PSCAE/UPII/E1A could selectively replicate in bladder cancer cells, thus causing specific tumor cell lysis. The replicative potential is a crucial factor in determining the therapeutic efficacy of oncolytic adenoviruses. However, viral replication is attenuated by the low-activity promoter that we used, thus compromising viral cytotoxicity. In this study, we investigated the effect of the cell cycle-dependent kinase inhibitor p21/Waf-1 on an adenovirus...

BACKGROUND: Non-Negative Matrix factorization has become an essential tool for feature extraction in a wide spectrum of applications. In the present work, our objective is to extend the applicability of the method to the case of missing and/or corrupted data due to outliers. RESULTS: An essential property for missing data imputation and detection of outliers is that the uncorrupted data matrix is low rank, i.e. has only a small number of degrees of freedom. We devise a new version of the Bregman proximal idea which preserves nonnegativity and mix it with the Augmented Lagrangian approach for simultaneous reconstruction of the features of interest and detection of the outliers using a sparsity promoting ℓ 1 penality...

INTRODUCTION: Ileocystoplasty is the standard technique used for bladder augmentation, and has been used widely for decades. However, it is known to be associated with complications such as stone formation, mucus production, metabolic acidosis, urinary tract infections, intestinal obstruction, and a long-term risk of bladder cancer. Seromuscular bladder augmentation (SMBA) is an alternative to the standard ileocystoplasty, and has been associated with a lower incidence of bladder stones...

BACKGROUND: Laparoscopic repair of the hiatal hernia is associated with a recurrence rate between 12% and 42% depending on the defect size. Although the impact of hiatal reinforcement on long-term recurrence remains controversial, the main limitation of this approach has been the risk of adverse events related with the use of synthetic materials in the vicinity of the esophagus. METHODS: A total of 14 female domestic pigs underwent laparoscopic primary hiatal hernia repair of a simulated defect in the esophageal hiatus...

BACKGROUND: Combined uterine and urinary bladder rupture following prolonged obstructed labor is indeed a momentous uro-obstetric emergency. The urinary bladder involvement is distinctly rare in the absence of factors that predispose the bladder to be adherent to the lower uterine segment and is quite unusual in a primigravida. OBJECTIVE: To report a rare case of uterine rupture involving urinary bladder secondary to a prolonged obstructed labor in a primigravida from a low resource setting...

Intravesical Bacillus Calmette-Guérin (BCG) has long been the gold standard treatment of nonmuscle invasive bladder cancer. Recently, there has been an emergence of novel immunotherapeutic agents, which have shown promise in the treatment of urothelial cell carcinoma. These agents aim to augment, modify, or enhance the immune response. Such strategies include recombinant BCG, monoclonal antibodies, vaccines, gene therapy, and adoptive T-cell therapy. Here, we review the emerging immunotherapeutics in the treatment of nonmuscle invasive bladder cancer...

Partial/extended partial cystectomy (EPC) is the most common surgery done for localized urachal malignancies. However, sometimes, after EPC, patients may be left with small bladder remnant, reconstruction of which will result in very small capacity bladder with resultant severe storage voiding symptoms. We report a case of urachal adenocarcinoma, in which when a small bladder remnant was left post-EPC, instead of proceeding with radical cystectomy (RC) and neobladder (the standard alternative), bladder augmentation was done with good oncological and voiding outcome...

Helicobacter Pylori was previously demonstrated at gastric patch after gastrocystoplasty and a possible relationship with acid-haematuria syndrome was established after symptomatic relief by medical treatment. We present the long term outcome of a male bladder exstrophy patient after gastrocystoplasty. There was past history of bladder perforation, acid haematuria syndrome and treatment of HP and recurrent urinary tract infections, noncompliance on regular follow-up and cadaveric renal transplantation. At the preoperative evaluation for renal transplantation HP was present in the biopsy samples collected during gastroscopy and cystoscopy...
