BACKGROUND Chronic kidney disease is a graded and independent risk factor for substantial comorbidity and death. We aimed to examine new onset of chronic kidney disease in patients with small, renal cortical tumours undergoing radical or partial nephrectomy. METHODS We did a retrospective cohort study of 662 patients with a normal concentration of serum(More)
PURPOSE Few published studies have simultaneously analyzed multiple prognostic factors to predict recurrence after surgery for conventional clear cell renal cortical carcinomas. We developed and performed external validation of a postoperative nomogram for this purpose. We used a prospectively updated database of more than 1,400 patients treated at a single(More)
OBJECTIVE To evaluate the clinical outcome of patients undergoing partial nephrectomy (PN) for renal cortical tumours who had a positive surgical margin (SM), as recent studies have shown that a minimal SM is required to achieve equivalent disease-free survival (DFS). PATIENTS AND METHODS Between 1989 and 2005, 777 PNs were performed at the authors'(More)
OBJECTIVE To compare the outcomes of patients who had a elective partial nephrectomy (PN) or radical nephrectomy (RN) for clear cell renal cell carcinoma (RCC) of 4-7 cm. PATIENTS AND METHODS From March 1998 to July 2004, 45 and 151 patients underwent PN and RN, respectively, for clear cell RCC. A multivariate Cox model was constructed for disease-free(More)
OBJECTIVE To report the experience of partial nephrectomy in patients with a solitary kidney at one institution, with analysis of renal function, complications, oncological efficacy and survival. PATIENTS AND METHODS We identified 54 consecutive patients with a solitary kidney who had a partial nephrectomy between December 1989 and July 2003. Variables(More)
PURPOSE Population studies link increased BMI with an increased risk of cancer and cancer mortality and in particular a greater risk of RCC. We evaluated the impact of BMI and other clinical/pathological characteristics on survival in patients with RCC treated with radical or partial nephrectomy. MATERIALS AND METHODS Between 1995 and 2003 patients(More)
BACKGROUND The clinical staging of renal cortical tumors traditionally has not evaluated the potential effect of histological subtypes on survival. Evidence suggests that conventional clear cell renal cell carcinoma (RCC) and nonconventional clear cell RCC (chromophobe and papillary) have different metastatic potential. Using a large renal tumor database,(More)
PURPOSE Prognostic factors for patients with metastatic renal cell carcinoma (RCC) are well established. However, the risk profile is unknown for patients with recurrent RCC after a nephrectomy for localized disease. PATIENTS AND METHODS From January 1989 to July 2005, we identified patients with localized RCC treated by nephrectomy who subsequently(More)
PURPOSE Standardized criteria for reporting the early complications of urological procedures are lacking. We reviewed the early complications of radical nephrectomy (RN) and partial nephrectomy (PN) in a large contemporary cohort using a standardized complication grading scale. MATERIALS AND METHODS Between 1995 and 2002, 1,049 patients underwent RN (66%)(More)
PURPOSE We analyzed prognostic factors to predict renal insufficiency after partial or radical nephrectomy. We developed and performed internal validations of a postoperative nomogram for this purpose. We used a prospectively updated renal tumor database of more than 1,500 patients. MATERIALS AND METHODS From July 1989 to October 2003, 161 partial(More)
