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.

To show the underlying variability in peri-operative mortality after radical cystectomy (RC) by analysing failure-to-rescue (FTR) rates, i.e. deaths after complications. ⋯ Whereas both patient and hospital characteristics were associated with increased odds of FTR, the occurrence of septicaemia and cardiac complications were the most strongly associated with a higher risk of in-hospital mortality.

To evaluate the mid-term effects of haemostatic sealant application during tubeless percutaneous nephrolithotomy (PCNL) on renal drainage and histology in an in vivo porcine study. ⋯ Based on these experimental results, the safety of the application of haemostatic sealants in tubeless PCNL should be reassessed, focusing not only on the potential of such materials to occlude urinary drainage but also on their effect on renal histology. Further investigation is considered necessary.

To identify and assess potential hazards in robot-assisted urological surgery. To develop a comprehensive checklist to be used in operating theatres with robotic technology. ⋯ HFMEA identified hazards in an operating theatre with innovative robotic technologies which has led to the development of a surgical safety checklist. Further work will involve validation and implementation of the checklist.
