PURPOSE The introduction of the da Vinci Surgical System to perform complex reconstructive procedures, such as repair of ureteropelvic junction obstruction, has helped to overcome some of the technical challenges associated with laparoscopy. We review our large multi-institutional experience with long-term followup of robotic dismembered pyeloplasty. (More)
OBJECTIVE To compare the surgical outcomes of elderly patients with renal masses treated with laparoscopic partial nephrectomy (LPN) or laparoscopic cryoablation (LCA). PATIENTS AND METHODS All 15 patients who had LCA at the authors' institution between May 2003 and July 2005 were included, and compared with a matched cohort of 15 patients selected by(More)
OBJECTIVES Stone disease is a rare complication after renal transplantation, and the management of these stones can be difficult. In many cases, the best modality to treat stones in transplanted kidneys/ureters is with a percutaneous approach. The goal of this study was to review our series of percutaneous nephrolithotomy (PNL) to evaluate the success rates(More)
BACKGROUND AND PURPOSE Intracorporeal suturing can be challenging, especially in the case of laparoscopic partial nephrectomy. During these procedures, suturing must reapproximate renal tissue to achieve hemostasis but not tear through tissue. We present a new device, the ANPA Suturelock, which can be adjusted to increase or decrease suture tension,(More)
Histone deacetetylases (HDACs) are a group of corepressors of transcriptional activators and their levels of expression are potentially dysregulated in prostate cancer. Certain inhibitors of histone deacetylases show anti-tumor activity in prostate cancer cell lines. Here, we systemically studied the expression of HDACs in human prostate cancer and the(More)
PURPOSE Reconstructive surgery of the upper urinary tract can be complicated. During the last 2 decades minimally invasive techniques have emerged as viable options for these complex procedures. We reviewed our experience with robotic surgery for upper urinary tract reconstruction. MATERIALS AND METHODS Between May 2002 and December 2006, a single surgeon(More)
Body mass index (BMI) has been shown to influence the outcome of various surgical procedures. The purpose of this study is to assess the relationship between BMI, gender, and the distribution of subcutaneous and perirenal fat. A retrospective review was performed for 123 patients who underwent radical or partial nephrectomy. Preoperative CT scans were(More)
PURPOSE Primary hyperparathyroidism is a common cause of hypercalcemia with resulting hypercalciuria and a subset of these patients with primary hyperparathyroidism present with urolithiasis. We evaluated the metabolic stone profile in patients presenting for parathyroid surgery and determined whether there were differences between those with and without a(More)
We recently demonstrated that EGFR protein overexpression is more common in African American (AA) prostate cancer patients compared to Caucasian patients. We further examine EGFR dysregulation by determining EGFR mutation status in the tyrosine kinase (TK) domain in prostate cancer patients of different ethnicity. Normal and tumor DNA from 89 radical(More)
