To assess the negative predictive value (NPV) of multiparametric magnetic resonance imaging (mpMRI) for detection of prostate cancer (PCa) in routine clinical practice and to identify characteristics of patients for whom mpMRI fails to detect high-grade (Gleason score ≥7) disease.We reviewed our prospectively maintained database of consecutive men who received prostate mpMRI at our institution, interpreted...
To evaluate the nationwide practice patterns of the management of acute urinary retention (AUR) secondary to urethral stricture (US) in an emergency department (ED) setting.We used the 2006-2010 Nationwide Emergency Department Sample to identify men with US who received treatment for AUR. We excluded patients with benign prostatic hyperplasia, vesicourethral anastomotic stenosis, neurogenic bladder,...

On occasion, patients undergo URS and it is discovered that the stone has already passed.Retrospective chart review was conducted on all URS cases for renal and ureteral stones performed by a...
To evaluate the hypothesis that intravesical instillation of epinephrine would attenuate bladder hemorrhage in a rat model of cyclophosphamide (CYP)-induced hemorrhagic cystitis. Female Sprague-Dawley rats were divided into seven treatment groups: positive control (CYP, 150 mg/kg), negative control (epinephrine, 10 μg/mL), intravesical instillation of normal saline (vehicle) and epinephrine (2...
