Data show high stone-free rates with URS LL in all locations of the urinary tract and with all stone types and sizes. Recent data comparing LL with dusting versus basketing suggest higher rates of residual fragments with dusting but less utilization of ureteral access sheaths and potentially shorter operative times. Differences in postoperative complications, re-intervention rates, and other outcome parameters are not yet clear. Interpretation of published data is problematic due to variability in laser settings, follow-up intervals, and definitions for what constitutes stone-free status. URS has overtaken shock wave lithotripsy in the last decade as the most commonly utilized surgical approach for treating urolithiasis. Two primary strategies have emerged as the most common techniques for performing LL: dusting and basketing. There is a relative paucity of data examining the difference in these techniques as it pertains to peri-operative outcomes and overall success. We attempt to synthesize this data into evidence-based and experience-based recommendations.

Abbreviations & AcronymsObjective: To investigate the clinical significance of preoperative aspects and dimensions used for anatomic (PADUA) and radius exophytic/endophytic nearness anterior/posterior location (RENAL) scoring systems for renal neoplasms in patients undergoing laparoscopic partial nephrectomy. Methods: A retrospective analysis was carried out on clinical data of 245 Chinese patients with renal neoplasms undergoing laparoscopic partial nephrectomy from June 2008 to June 2012. The perioperative complications and variables, as well as PADUA and RENAL score, were compared. Results: The PADUA and RENAL scoring systems were significantly associated with percent change in estimated glomerular filtration rate (P = 0.032 and P = 0.026 respectively), whereas the RENAL scoring system was also significantly associated with warm ischemia time (P = 0.032). On multivariate analysis, both scores were able to predict percent change in estimated glomerular filtration rate (PADUA, P = 0.011; RENAL, P = 0.028). There were no significant associations between the two scoring systems assessed and the occurrence of complications or tumor stage. The correlation between PADUA classification and RENAL nephrometry score was significant (P < 0.0001). Fleiss' generalized kappa was 0.69-0.89 for the various components of the PADUA score and 0.67-0.89 for the RENAL nephrometry components. Conclusions:The PADUA classification and RENAL nephrometry score are comprehensive assessment tools for delineating renal tumor anatomy. The reproducibility of the PADUA and RENAL scores is substantial, but further research is required to evaluate its performance in more accurately predicting operative and patient-related outcomes.

• 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. Objective• To present a comparative analysis of peri-operative outcomes for >200 cases of conventional laparoscopic donor nephrectomy (LDN) and laparoendoscopic single site donor nephrectomy (LESS-DN). Patients and Methods• From 2006 to 2011, 213 donor nephrectomies were performed by two surgeons (R.E.L and W.A.M.) at a tertiary transplant centre. The approach changed from conventional LDN to LESS-DN over the course of the series.• The two approaches were compared retrospectively and evaluated for differences in peri-operative outcomes.• Statistical significance was assessed using Student's t-test and chi-squared analysis. Results• A total of 111 patients underwent LDN and 102 patients underwent LESS-DN. • Total operating time was significantly longer in the LESS-DN group (206.1 vs 181.9 min, P < 0.001), but LESS-DN resulted in less intra-operative blood loss (61.5 mL vs 85.9 mL, P < 0.001) and shorter warm ischaemia times (4.4 vs 5.0 min, P = 0.01).• There were no significant differences in analgesic requirements, subjective pain scores, length of hospital stay, postoperative graft function, or donor's postoperative glomerular filtration rate between the two approaches.• Complication rates were low regardless of the approach, and there were no major complications (>grade II) in the LESS-DN group. Conclusions• 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.

Introduction: Data suggest many U.S. physicians experience burnout, affecting up to 65% of U.S. urology resident physicians. We implemented a multifaceted Urology Resident Wellness Curriculum and measured its effect on burnout reported among our trainees.Methods: We created a 5-pronged Resident Wellness Curriculum: 1) faculty-sponsored Resident Wellness Fund, 2) social groups between 1 faculty and 2e3 trainees, 3) one-on-one structured mentorship, 4) resident-organized social outings using the Resident Wellness Fund, and 5) wellness education. We administered 2 validated burnout questionnaires, the Maslach Burnout Index-Human Services Survey and the Expanded Mayo Physician Well Being Index, to our resident physicians at 4 time points, immediately before and following curriculum implementation. At study conclusion, resident physicians were asked to rank the most meaningful interventions.Results: At 4 timepoints over 3 academic years, 54 completed instruments were collected from 32 unique resident physicians. Initial Maslach Burnout Index survey data indicated high levels of Depersonalization and Emotional Exhaustion with moderate levels of Personal Accomplishment. Over the study period, there was improvement in Depersonalization from high to moderate (28% decrease, p¼0.04), improvement in Emotional Exhaustion from high to moderate (20% decrease, p¼0.15) and preserved moderate Personal Accomplishment. The average Physician Well Being Index score decreased by 52% (p¼0.006), demonstrating decreased levels of distress. Resident-organized social outings were ranked as the most meaningful intervention, with 63% of participants ranking it first.Conclusions: Rates of urology resident physician burnout were observed to be high at baseline, but improved significantly after introduction of a purposeful Resident Wellness Curriculum.
