To investigate the changing pattern of antimicrobial resistance in Escherichia coli urinary tract infection over an eleven year period, and to determine whether E. coli antibiotic resistance rates vary depending on whether the UTI represents a nosocomial, community acquired or urology patient specific infection. ⋯ E. coli remains the commonest infecting uropathogen in the community and hospital setting with its incidence climbing from 50 to 60% of UTIs over the 11-year period. Neither penicillins nor trimethoprim represent suitable empirical antimicrobials for UTI and ciprofloxacin resistance in this Dublin-based study renders it unsuitable empirical therapy for nosocomial UTIs and UTIs in the urology population. The dramatic 11-year rate increase in gentamicin resistance is of paramount concern.

Review Comparative Study
Systematic review of surgical treatments for benign prostatic hyperplasia and presentation of an approach to investigate therapeutic equivalence (non-inferiority).
• To assess the potential additional benefit of non-standard vs standard surgical treatments for benign prostatic hyperplasia (BPH) and to present a new methodological approach to investigate therapeutic equivalence (non-inferiority) regarding symptom reduction. ⋯ • No proof of superiority for symptom reduction has been shown for non-standard surgical treatments in patients with BPH. • There is a lack of high-quality RCTs and trials designed to investigate non-inferiority. • Future studies should define a non-inferiority threshold (ideally, uniform) a priori, so that results of individual studies are interpretable and comparable, and future systematic reviews should consider this issue.

What's known on the subject? and What does the study add? The curative treatment of prostate cancer includes surgery, external beam radiation or interstitial radiation. However, a high percentage of patients may develop recurrent disease, which is often localised. The possibilities of treatment in these cases, including surgery or adjuvant radiotherapy, are not well defined. ⋯ A newer initiative conducted in Spain in a larger series of 42 patients with failure following radical prostatectomy involves brachytherapy with RAPID Strand™(125) I seeds and real-time placement. The 5-year bDFS rate was 88.6% and cancer-specific survival was 97%; complication rates were low. Optimization of salvage brachytherapy is under way and involves accurate placement of seeds, dose optimization and optimal patient selection.

• Intravesical immunotherapy or chemotherapy for non-muscle invasive bladder cancer is a well-established treatment for preventing or delaying tumour recurrence after tumour resection. However, up to 70% of patients may fail and new intravesical agents with improved effectiveness are needed. Gemcitabine is a relatively new anticancer drug that has shown activity against bladder cancer. • To systematically review the literature on the effectiveness and toxicity of intravesical gemcitabine for non-muscle invasive bladder cancer (NMIBC). • MEDLINE, EMBASE, CINAHL, the Cochrane database of systematic reviews, LILACS, SCOPUS, BNI, Biomed Central, Web of Science and BIOSIS were searched to identify trials of intravesical gemcitabine for the treatment of NMIBC. ⋯ Gemcitabine may be more active than MMC with a lower toxicity profile. • Compared with intravesical BCG therapy, gemcitabine had similar effects in intermediate-risk patients, less effective in high-risk patients and superior in BCG-refractory patients. However, each randomised trial identified represents a different clinical setting in NMIBC and therefore the evidence base is limited. Consequently these data should be interpreted with caution until further corroborative evidence becomes available. • Intravesical gemcitabine is a promising drug that may add to the urologist's options in treating patients with NMIBC.

To undertake a detailed analysis of the British Association of Urological Surgeons (BAUS) Section of Oncology Complex Operations Database to report UK outcomes of radical prostatectomy (RP) with particular reference to the case volume of the operating surgeon. ⋯ High volume surgeons have less peri-operative and postoperative complications and better surgical and disease-free outcomes than low volume surgeons. In the UK, raising the current minimum Improving Outcomes Guidance threshold from five RP cases per surgeon per annum to no less than 20 (and ideally to 35 or more cases per annum) could potentially improve overall outcomes.
