PURPOSE We evaluated the long-term natural history of renal function after radical cystectomy with urinary diversion and determined factors associated with decreased renal function. MATERIALS AND METHODS We reviewed the records of 1,631 patients who underwent radical cystectomy between 1980 and 2006. The estimated glomerular filtration rate was calculated(More)
PURPOSE We present a novel concept of zero ischemia anatomical robotic and laparoscopic partial nephrectomy. MATERIALS AND METHODS Our technique primarily involves anatomical vascular microdissection and preemptive control of tumor specific, tertiary or higher order renal arterial branch(es) using neurosurgical aneurysm micro-bulldog clamps.

BACKGROUND Ischemic injury impacts renal function outcomes following partial nephrectomy. Efforts to minimize, better yet, eliminate renal ischemia are imperative. OBJECTIVE Describe a novel technique of "zero ischemia" laparoscopic (LPN) and robotic-assisted (RAPN) partial nephrectomy. DESIGN, SETTING, AND PARTICIPANTS Data were prospectively collected(More)
BACKGROUND Robot-assisted and laparoscopic partial nephrectomies (PNs) for medial tumors are technically challenging even with the hilum clamped and, until now, were impossible to perform with the hilum unclamped. OBJECTIVE Evaluate whether targeted vascular microdissection (VMD) of renal artery branches allows zero-ischemia PN to be performed even for(More)
PURPOSE While multiple independent clinicopathological variables are associated with the outcome of radical cystectomy for bladder cancer, limited prediction tools exist to facilitate individualized risk assessment. We developed the SPARC (Survival Prediction After Radical Cystectomy) score, a prediction model for bladder cancer specific survival after(More)
BACKGROUND The value of lymph node dissection (LND) in the treatment of bladder urothelial carcinoma is well established. However, standards for the quality of LND remain controversial. OBJECTIVE We compared the distribution of lymph node (LN) metastases in a two-institution cohort of patients undergoing radical cystectomy (RC) using a uniformly applied(More)
OBJECTIVE Recent studies have shown a relative risk reduction in the incidence of prostate cancer in patients taking metformin. However, there are conflicting findings on the effect of metformin on established cases of prostate cancer. In this study we evaluated the effect of metformin on survival and pathologic outcomes in established prostate cancer. (More)
PURPOSE Radical cystectomy in patients with a history of pelvic radiation therapy is often a challenging and morbid procedure. We report early complication rates in patients undergoing cystectomy and urinary diversion after high dose pelvic radiation. MATERIALS AND METHODS From 1983 to 2008, 2,629 patients underwent cystectomy with urinary diversion at a(More)
PURPOSE OF REVIEW As familiarity with laparoscopic partial nephrectomy (LPN) has grown, application has expanded into increasingly complex cases. In this review, we present a recent series describing use of LPN in specific clinical scenarios and describe common technical modifications commonly employed in each case. In addition, we discuss modifications to(More)
