The aim of this study was to evaluate the recurrence rate of simultaneous transurethral resection of bladder cancer and prostate (TURBT+TURP) in the treatment of non-muscle invasive bladder cancer (NMIBC) with benign prostatic hyperplasia (BPH). We searched PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and the ISI Web of Knowledge databases from their establishment until March 2012, to collect all the original studies on TURBT+TURP vs. TURBT alone in the treatment of NMIBC with BPH. After screening the literature, methodological quality assessment and data extraction was conducted independently by two reviewers and meta-analysis was performed using the RevMan 5.1 software. The quality of data was assessed using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Eight studies, including seven non-randomized concurrent controlled trials (NRCCTs) and one randomized controlled trial (RCT), involving a total of 1,372 patients met the criteria. Meta-analyses of NRCCTs showed that in the TURBT+TURP group, overall recurrence rates were lower [odds ratio (OR), 0.76; 95% confidence interval (CI), 0.60-0.96; P=0.02] and the difference was statistically significant. The postoperative recurrence rate in the prostatic fossa/bladder neck (OR, 0.96; 95% CI, 0.64-1.45; P=0.86) and bladder tumor progression rates (OR, 0.96; 95% CI, 0.49-1.87; P=0.91) were similar between the TURBT+TURP and TURBT groups, but the difference was not significant. According to the GRADE approach, the level of evidence was moderate or low. Only one RCT demonstrated that overall postoperative tumor recurrence rates, recurrence rates at prostate fossa/bladder neck and bladder tumor progression rates between simultaneous groups and control groups were almost equal. There was no significant difference (P>0.05), and the level of evidence was moderate. For patients with NMIBC and BPH, simultaneous resection did not increase the overall recurrence rate of bladder tumors, it also did not cause metastasis and tumor progression, but it may reduce the recurrence rate. However, due to the low quality of investigations included in the present study, careful selection was necessary, and more large-scale and high-quality randomized controlled trials are also required for further confirmation.

A research program of the NIA which focuses on neuroscience, aging biology, and translational gerontology. The central focus of the program's research is understanding age-related changes in physiology and the ability to adapt to environmental stress, and using that understanding to develop insight about the pathophysiology of age-related diseases. The IRP webpage provides access to other NIH resources such as the Biological Biochemical Image Database, the Bioinformatics Portal, and the Baltimore Longitudinal Study of Aging.
View all literature mentionsA bibliographic database that provides a highly concentrated source of reports of randomized controlled trials. Records contain the list of authors, the title of the article, the source, volume, issue, page numbers, and, in many cases, a summary of the article (abstract). They do not contain the full text of the article. Cochrane Groups maintain and update Specialized Registers, which are collections of controlled trials relevant to the groups. CENTRAL is comprised of these Specialized Registers, relevant records retrieved from MEDLINE and EMBASE, and records retrieved through handsearching (planned manual searching of a journal or conference proceedings to identify all reports of randomized controlled trials and controlled clinical trials). The Cochrane Collaboration contracts a technology company, Metaxis, to merge the records from the sources outlined above and provide a data feed to the publisher. New and changed data are delivered to the publisher on a monthly basis.
