We previously reported that miR-1 is among the most consistently down-regulated miRs in primary human prostate tumors. In this follow-up study, we further corroborated this finding in an independent data set and made the novel observation that miR-1 expression is further reduced in distant metastasis and is a candidate predictor of disease recurrence.(More)
BACKGROUND We present initial data on the construct, content, and face validity of the LAPMentor (Simbionix), virtual reality laparoscopic surgical simulator. STUDY DESIGN Medical students (MS), residents and fellows (R/F), and experienced laparoscopic surgeons (ES), with < 30 laparoscopic cases per year (ES<30) and those with > 30 laparoscopic cases per(More)
PURPOSE Laparoscopic partial/wedge nephrectomy, similar to laparoscopic radical prostatectomy, is a technically challenging procedure that is performed by a limited number of expert laparoscopic surgeons. The incorporation of a robotic surgical interface has dramatically increased the use of minimally invasive pelvic surgery such that robotic laparoscopic(More)
OBJECTIVES The processing of standard flexible cystoscopes is time-consuming and potentially hazardous to healthcare staff. We evaluated a novel flexible cystoscope system containing a disposable sheath, which obviates the need for chemical processing. METHODS A total of 100 patients undergoing office cystoscopy were randomized into a "sheath" or a(More)
INTRODUCTION We previously reported the benefit of meticulous apical dissection in reducing positive surgical margins (SM+) at the apex. Herein we assess whether a more aggressive urethral transection will reduce positive margins and whether reduced urethral length affects return to continence. TECHNICAL CONSIDERATIONS All data were collected(More)
PURPOSE To update our short-term potency outcomes from a cautery-free (CFT) versus bipolar cautery technique to preserve the neurovascular bundles (NVB) during robotic laparoscopic radical prostatectomy (RLP). PATIENTS AND METHODS Previously, we reported on 3-month potency outcomes in 23 men, which we now extend to 51 men. All men met three criteria: age(More)
BACKGROUND AND PURPOSE The effect of laser pulse width on calculus retropulsion during ureteroscopic lithotripsy is poorly defined because of the limited availability of variable pulse-width lasers. We used an adjustable pulse-width Ho:YAG laser to test the effect of pulse width on in vitro phantom-stone retropulsion and fragmentation efficiency. METHODS(More)
We describe using hemostatic gelatin matrix (FloSeal; Baxter Inc., Irvine, CA) to provide hemostasis of the tract after percutaneous nephrolithotomy, thereby obviating a nephrostomy tube. For patients who are rendered stone free, a 7F, 11.5-mm occlusion balloon catheter, passed retrograde, is used to occlude the collecting system at the level of entry of(More)
Smokers develop metastatic prostate cancer more frequently than nonsmokers, suggesting that a tobacco-derived factor is driving metastatic progression. To identify smoking-induced alterations in human prostate cancer, we analyzed gene and protein expression patterns in tumors collected from current, past, and never smokers. By this route, we elucidated a(More)
BACKGROUND AND PURPOSE There have been several reports of rhabdomyolysis occurring after prolonged laparoscopic procedures in the flank position. Accordingly, we evaluated interface pressures between the skin and three commonly used operating room table surfaces. The aim of our study was to determine if pressure changes could be related to body mass index(More)
