Kidney stones have been rising in prevalence in the United States and worldwide, and represent a significant cost burden. Cost effectiveness research in this area may enable improvements in treatment efficiency that can benefit patients, providers and the healthcare system. There has been limited research in the cost effectiveness of surgical interventions(More)
BACKGROUND AND OBJECTIVES Laparoscopic Doppler technology has previously been reported to help identify vasculature during laparoscopy. Recently, we published our initial experience with this technology during laparoscopic radical nephrectomy, laparoscopic nephroureterectomy, laparoscopic partial nephrectomy, and robotic-assisted laparoscopic pyeloplasty.(More)
OBJECTIVE Robotic surgical skill development is central to training in urology as well as in other surgical disciplines. Here, we describe a pilot study assessing the relationships between robotic surgery simulator performance and 3 categories of activities, namely, videogames, musical instruments, and athletics. DESIGN A questionnaire was administered to(More)
Prostate cancer (PCa) recurrences are often predicted by assessing the status of surgical margins (SM)- positive surgical margins (PSM) increase the chances of biochemical recurrence by 2-4 times which may lead to PCa recurrence. To this end, an electrical impedance acquisition system with a microendoscopic probe was employed in an ex-vivo study of human(More)
BACKGROUND Intraoperative ultrasonography has proven to be a useful tool for tumor identification during robot-assisted laparoscopic partial nephrectomy (RALPN). However, its utility is limited in renal tumors that are completely endophytic and isoechoic in nature. We present a novel approach to intraoperative tumor identification using preoperative(More)
Prostate cancer management strategies are evolving with increased understanding of the disease. Specifically, there is emerging evidence that “low-risk” cancer is best treated with observation, while localized “high-risk” cancer requires aggressive curative therapy. In this study, we evaluated trends in management of prostate cancer in New Hampshire to(More)
