The percutaneous nephrolithotomy stone-free rate can be predicted using preclinical data and radiological information. We present a nephrolithometric nomogram for percutaneous nephrolithotomy.

At almost 1 year followup stent failure due to extrinsic compression occurred in nearly half of treated patients. Analysis of data revealed a diagnosis of cancer, baseline mild renal insufficiency and metastatic disease requiring chemotherapy or radiation as predictors of stent failure. Managing extrinsic compression by retrograde stenting continues to be a practical but guarded decision and should be tailored to each patient.

This study failed to demonstrate a statistically significant difference in stone-free rates between SWL and URS for the treatment of small lower pole renal calculi. However, SWL was associated with greater patient acceptance and shorter convalescence.

Objective To characterise the use of social media among members of the American Urological Association (AUA), as the use of social media in medicine has greatly expanded in recent years. Subjects and Methods In December 2012 to January 2013, the AUA e‐mailed a survey with 34 questions on social media use to 2000 randomly selected urologists and 2047 resident/fellow members. Additional data was collected from Symplur analytics on social media use surrounding the AUA Annual Meeting in May 2013. Results In all, 382 (9.4%) surveys were completed, indicating 74% of responders had an online social media account. The most commonly used social media platforms were Facebook (93%), followed in descending order by LinkedIn (46%), Twitter (36%) and Google+ (26%). Being aged <40 years was an important predictor of social media use (83% vs 56%), with greater uptake among residents/fellows compared with attendings (86% vs 66%). Only 28% of respondents used social media partly or entirely for professional purposes. During the 2013 AUA Annual Meeting, there were >5000 tweets from >600 distinct contributors. Conclusion As of early 2013, among respondents to an e‐mail survey, most urologists and urology trainees used some form of social media, and its use in urology conferences has greatly expanded.

Standardization of the nomenclature applied to natural orifice transluminal endoscopic surgery (NOTES) and laparo-endoscopic single-site surgery (LESS) is essential as the body of literature continues to grow in order to allow clear and precise scientific communication. As the techniques continue to evolve, we propose that NOTES and LESS be designated as the common terms to define these new procedures in urology.

This study failed to demonstrate a statistically significant difference in stone-free rates between SWL and URS for the treatment of small lower pole renal calculi. However, SWL was associated with greater patient acceptance and shorter convalescence.

Video game aptitude appears to predict the level of laparoscopic skill in the novice surgeon. In this study, practicing video games did not improve one's laparoscopic skill significantly, but a larger study with more practice time could prove games to be helpful.
