BACKGROUND Adverse event reporting is highly variable and nonstandardized in urologic literature, especially for robot-assisted radical cystectomy (RARC). OBJECTIVE We sought to better characterize complications in patients after RARC using a standardized reporting methodology. DESIGN, SETTING, AND PARTICIPANTS Using a prospectively maintained,(More)
PURPOSE Positive surgical margins at radical cystectomy confer a poor prognosis. We evaluated the incidence and predictors of positive surgical margins in patients who underwent robot assisted radical cystectomy for bladder cancer. MATERIALS AND METHODS Using the International Robotic Cystectomy Consortium database we identified 513 patients who underwent(More)
OBJECTIVE • Robot-assisted radical cystectomy (RARC) remains controversial in terms of oncologic outcomes, especially during the initial experience. The purpose of this study was to evaluate the impact of initial experience of robotic cystectomy programs on oncologic outcomes and overall survival. PATIENTS AND METHODS • Utilizing a prospectively(More)
5075 Background: There is relatively little literature regarding the use of adjuvant chemotherapy following radical nephroureterectomy in the management of patients with upper tract urothelial carcinoma (UTUC). Our goal was to determine the incidence of receipt of adjuvant chemotherapy in high-risk patients and the ensuing effect on overall- and(More)
OBJECTIVE To evaluate our experience with tension-free transvaginal tape (TVT) placement for the management of stress urinary incontinence (SUI) in women who had previously undergone a failed midurethral synthetic sling (MUS) procedure. MATERIALS AND METHODS Ten women underwent retropubic TVT insertion for continued or recurrent SUI following a prior MUS(More)
PURPOSE Sunitinib is an approved treatment for metastatic renal cell carcinoma. We performed a prospective clinical trial to evaluate the safety and clinical response to sunitinib administered before nephrectomy in patients with localized or metastatic clear cell renal cell carcinoma. MATERIALS AND METHODS Patients with biopsy proven clear cell renal cell(More)
OBJECTIVES To evaluate the effect of previous robot-assisted radical prostatectomy (RARP) case volume on the outcomes of robot-assisted radical cystectomy. Little is known regarding the effect of previous robotic surgical experience on the implementation and execution of robot-assisted radical cystectomy. METHODS Using the International Robotic Cystectomy(More)
PURPOSE Data regarding clinical outcomes in elderly patients with renal cell carcinoma are scarce. We determined management, and overall and cancer specific survival in elderly patients with renal cell carcinoma. MATERIALS AND METHODS Using the Surveillance, Epidemiology, and End Results database we identified 59,944 patients who underwent partial or(More)
OBJECTIVE To evaluate the incidence of, and predictors for, lymphadenectomy in patients undergoing robot-assisted radical cystectomy (RARC) for bladder cancer. PATIENTS AND METHODS Utilizing the International Robotic Cystectomy Consortium (IRCC) database, 527 patients were identified who underwent RARC at 15 institutions from 2003 to 2009. After(More)
BACKGROUND Expert panels of colorectal surgeons consistently rank anastomotic leak as among the most important quality metrics for colectomies. Nonetheless, most administrative and clinical databases do not collect data on anastomotic leaks and rely on reported organ space surgical site infections (OSI) as a proxy for identifying anastomotic leaks.
