To investigate the prevalence and predictors associated with benign lesions in Korean patients after partial nephrectomy for presumed renal cell carcinoma (RCC) for lesions measuring ≤ 4 cm.We retrospectively investigated the medical records of 376 patients who underwent partial nephrectomy for presumed RCC with renal masses of size ≤ 4 cm between June 1997 and December 2008. Demographic and clinicopathologic...
To investigate the relationship between maspin expression and prognostic parameters in renal cell carcinoma (RCC) with relevance to vascular endothelial growth factor (VEGF) expression and microvessel density.One-hundred twenty-four patients with RCC of varying histologic types who underwent radical or partial nephrectomy were studied. The mean age of the patients was 59.4 years (range, 28-84). Maspin,...
To examine the long-term survival following radical prostatectomy in the population with high-risk prostate cancer. Despite considerable stage migration associated with widespread prostate-specific antigen screening, as many as one-third of incident prostate cancers have high-risk features. These patients are often treated with combined radiation and androgen deprivation therapy, and less is known...
Many centers have recently implemented posterior rhabdosphincter reconstruction (PRR) into robot-assisted radical prostatectomy (RARP) with the objective of earlier continence recovery. We comprehensively review the anatomic and functional changes occurring post prostatectomy along with the reconstructive techniques and published outcomes of PRR. Several case control studies show a better continence...
To evaluate the long-term outcomes of patients with high Gleason sum 8-10 at radical prostatectomy (RP) and to identify the predictors of prostate cancer-specific survival (CSS) in this cohort.The institutional RP database was queried. A total of 9381 patients with complete follow-up underwent RP from 1982 to 2008. Of these 9381 patients, 1061 had pathologic Gleason sum 8-10 cancer. The patient and...
To assess our institution's experience with the management of pathologic stage T3bNxM0 renal cell carcinoma with tumor thrombus confined to the renal vein treated with nephron-sparing surgery (NSS).Of the 492 patients who have undergone NSS at Columbia University from 1998 to 2009, 8 patients were found to have stage T3bNxM0 renal cell carcinoma (RCC) on final pathology. Records were reviewed for...
Although recommended management strategy for nonmuscle-invasive bladder cancer (NMIBC) involves a single postoperative intravesical therapy with mitomycin C (MMC), it is uncommonly used among urologists, in part because of potential increased costs. Our objective was to perform a 5-year cost analysis of this strategy within a single-provider health care environment.A decision-analytic model was used...
To determine whether narrow band imaging (NBI) improves detection of non–muscle-invasive bladder cancer over white-light imaging (WLI) cystoscopy.We conducted a prospective, within-patient comparison on 103 consecutive procedures on 95 patients scheduled for (re-) transurethral resection of a bladder tumor (84) or bladder biopsies (19) in the Academic Medical Center, Amsterdam (September 2007-July...
