PURPOSE Radical nephrectomy has traditionally been preferred to partial nephrectomy in patients with localized renal cell cancer because of its simplicity and established cancer control. Recent data suggest that these patients have significant competing risks of death, some of which may be increased by chronic renal insufficiency. Therefore, we compared(More)
PURPOSE Partial nephrectomy is effective for renal cell carcinoma when preservation of renal function is a concern. We present the 10-year followup of patients treated with nephron sparing surgery at our institution. MATERIALS AND METHODS Partial nephrectomy was performed in 107 patients with localized sporadic renal cell carcinoma before December 1988.(More)
BACKGROUND The safe duration of warm ischemia during partial nephrectomy remains controversial. OBJECTIVE Our aim was to evaluate the short- and long-term renal effects of warm ischemia in patients with a solitary kidney. DESIGN, SETTING, AND PARTICIPANTS Using the Cleveland Clinic and Mayo Clinic databases, we identified 362 patients with a solitary(More)
OBJECTIVE To evaluate the effects of warm ischemia time (WIT) and quantity and quality of kidney preserved on renal functional recovery after partial nephrectomy (PN). The effect of WIT relative to these other parameters has recently been challenged. METHODS We identified 362 consecutive patients with a solitary kidney who had undergone PN using warm(More)
PURPOSE Chronic kidney disease from medical causes is present in 25% to 30% of patients before surgery for renal cancer. Although chronic kidney disease due to medical causes is typically associated with a 2% to 5% annual renal functional decline and decreased overall survival, reduced glomerular filtration rate occurring only after surgery may not have the(More)
PURPOSE We used what is to our knowledge a new method to estimate volume loss after partial nephrectomy to assess the relative contributions of ischemic injury and volume loss on functional outcomes. MATERIALS AND METHODS We analyzed the records of 301 consecutive patients who underwent conventional partial nephrectomy between 2007 and 2010 with available(More)
BACKGROUND Extended oncologic outcomes after minimally invasive cystectomy have not been previously reported. OBJECTIVE To report outcomes of robot-assisted radical cystectomy (RARC) and laparoscopic radical cystectomy (LRC) for bladder cancer (BCa) at up to 12-yr follow-up. DESIGN, SETTING, AND PARTICIPANTS All 121 patients undergoing RARC or LRC for(More)
PURPOSE The R.E.N.A.L. (radius, exophytic/endophytic properties, nearness of tumor to collecting system or sinus, anterior/posterior) and centrality index nephrometry scores enable systematic, objective assessment of anatomical tumor features. We systematically compared these systems using item analysis test theory to optimize scoring methodology. (More)
PURPOSE We present a series of 400 patients with tumor in a solitary kidney who underwent open surgical partial nephrectomy performed by a single surgeon (ACN) with a primary focus on postoperative long-term kidney function. MATERIALS AND METHODS A total of 400 patients with sporadic nonfamilial kidney tumors in a solitary kidney underwent open partial(More)
BACKGROUND Radical cystectomy (RC) for bladder cancer is frequently associated with delayed gastrointestinal (GI) recovery that prolongs hospital length of stay (LOS). OBJECTIVE To assess the efficacy of alvimopan to accelerate GI recovery after RC. DESIGN, SETTING, AND PARTICIPANTS We conducted a randomized double-blind placebo-controlled trial in(More)
