To determine the relationship of preoperatively measured cardiorespiratory function, to the development of postoperative complications and length of hospital stay (LOS) in a cohort of patients undergoing radical cystectomy (RC), as RC and conduit formation is curative but is associated with significant postoperative morbidity and mortality. ⋯ In all, 82 patients underwent CPET before RC. Eight patients did not subsequently undergo RC and a further five did not exercise sufficiently to allow for appropriate determination of the cardiopulmonary variables of interest. There was a significant difference in LOS between those patients who had a major perioperative complication (Clavien score > 3) and those that did not (16 vs 30 days; P < 0.001; hazard ratio [HR] 3.6, 95% confidence interval [CI] 2.1-6.3). The anaerobic threshold (AT) remained as the only significant independent predictor variable for the presence or absence of major postoperative complications (odds ratio 0.74, 95% CI 0.57-0.97; P = 0.03). When the optimal predictive value of AT of 12 mL/min/kg was used as a fitness marker, there was a significant relationship between fitness and LOS (median LOS: 'unfit' 22 days vs 'fit' 16 days; HR 0.47, 95% CI 0.28-0.80; P = 0.006) CONCLUSION: Impaired preoperative cardiopulmonary reserve was related to major morbidity, prolonged LOS and increased use of critical care resource after RC. This has important health and economic implications for risk assessment, rationalisation of postoperative resource and the potential for therapeutic preoperative intervention with exercise therapy.

Comparative Study
Comparison of laparoendoscopic single site (LESS) and conventional laparoscopic donor nephrectomy at a single institution.
WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Most transplant centres harvest living donor kidneys via a conventional laparoscopic surgical approach. Laparoendoscopic single-site donor nephrectomy (LESS-DN) is a relatively novel minimally invasive approach that allows the surgery to be performed via a single incision. This technique may be advantageous in decreasing surgical morbidity and improving cosmetic outcomes, thus plausibly reducing the barriers to kidney donation. The study demonstrates the safety and feasibility of LESS-DN in a large consecutive series of kidney donors. Comparative analysis between LDN and LESS-DN showed that there was a significant decrease in intra-operative blood loss and allograft warm ischaemia time in the LESS-DN group, but also a significant increase in operating time. Other peri-operative outcomes were similar between the two approaches. Evaluation of the LESS-DN cases alone revealed that, the operating times did not significantly change through the course of the series. Using this outcome as a surrogate for technical difficulty suggests a relatively shallow learning curve for LESS-DN. ⋯ In experienced hands, LESS-DN results in peri-operative outcomes similar to those of conventional LDN without compromising donor safety, while providing a desirable cosmetic result. For surgeons familiar with LDN, transitioning to the LESS approach using this technique appears to have a relatively short learning curve.

Randomized Controlled Trial Comparative Study
Effect of remote ischaemic preconditioning on renal protection in patients undergoing laparoscopic partial nephrectomy: a 'blinded' randomised controlled trial.
To evaluate whether remote ischaemic preconditioning (RIPC) reduces renal injury in patients undergoing laparoscopic partial nephrectomy (LPN). ⋯ In patients undergoing LPN, RIPC using transient lower limb ischaemia may reduce renal impairment in the short term, but failed in the longer term despite a non-significant trend in favour of RIPC. These novel data support the need for a larger study of RIPC during LPN surgery.

Randomized Controlled Trial Multicenter Study Comparative Study
Impact of the European Randomized Study of Screening for Prostate Cancer (ERSPC) on prostate-specific antigen (PSA) testing by Dutch general practitioners.
To determine the impact of the European Randomized Study of Screening for Prostate Cancer (ERSPC) publication in 2009 on prostate-specific antigen (PSA) level testing by Dutch general practitioners (GPs) in men aged ≥40 years. ⋯ After the ERSPC publication primary PSA testing as well as follow-up testing decreased. Follow-up testing seemed not to be adequate after an abnormal PSA result. The reasons for this remain unclear.

Clinical Trial
Refractory chronic pelvic pain syndrome in men: can transcutaneous electrical nerve stimulation help?
To evaluate the effect of transcutaneous electrical nerve stimulation (TENS) for treating men with refractory chronic pelvic pain syndrome (CPPS). ⋯ TENS may be an effective and safe treatment for refractory CPPS in men, warranting randomized, placebo-controlled trials.
