Background: Intravesical instillation of analgesic and anticholinergic drugs have shown efficacy in the treatment of pain and voiding symptoms. Unfortunately, drug loss with urination and dilution in the bladder limit their durability and clinical usefulness. We have recently developed and tested in vitro, a sustained delivery system (TRG-100) of fixed-dose combination of lidocaine and oxybutynin designed to allow for a longer exposure of the urinary bladder to the drugs.

Introduction: Transrectal ultrasound is utilized as an auxiliary tool when performing a prostate biopsy, but its sensitivity and specificity are low. Performing prostate multiparametric magnetic resonance imaging (mp-MRI) before prostate biopsy can increase the probability to detect aggressive prostate cancer while decreasing the probability to detect indolent prostate cancer, thereby assisting in the selection of patients before the biopsy. The Israel Basket of Health Services does not include prostate mpMRI prior to the first prostate biopsy.

Background: Circumcision is one of the most performed surgical procedure in the world, often performed for nontherapeutic reasons. Depending on cultural and social backgrounds, the procedure may be performed by various sources; from trained health care practitioners to laypeople, giving rise to different frequencies and types of complications. Glans injury during ritual circumcision is a rare yet serious complication due to its associated morbidity and long-term consequences.

The management of primary and recurrent bulbar urethral stricture disease has been a source of controversy with the choice being between endoscopic urethrotomy and open urethroplasty. Further debate exists with regard to the choice of urethroplasty--either excision and primary anastomosis (EPA) or augmentation with a graft or flap. Using PubMed, a 35-year literature search was conducted (1975-2010) for peer-reviewed articles on bulbar strictures treated using EPA.

Purpose Of Review: The field of urogenital trauma is undergoing constant improvement mainly due to better diagnostic tools, a shift toward standardized treatments and better trauma care. The purpose of this review is to summarize the most relevant studies published within the last 3 years on the subject.

Recent Findings: Computerized tomography grading of renal trauma is an excellent predictor of the need for surgery and the final renal outcome in these patients, as most patients can be treated conservatively.

Purpose: It has been shown that the incidence of de novo vesicoureteral reflux following unilateral endoscopic correction is low and does not justify prophylactic injection into the nonrefluxing ureter. We analyzed whether we should routinely treat each ureter in patients with a history of bilateral vesicoureteral reflux in whom reflux previously disappeared spontaneously on 1 side.

Materials And Methods: Between 1991 and 2005, 458 children underwent endoscopic correction of unilateral vesicoureteral reflux.
