Timing of magnesium supplementation in patients with nephrolithiasis: A randomized controlled trial.

Background: Urinary magnesium plays an important role in the prevention of calcium oxalate stone formation, but the role of magnesium supplementation has yet to be clearly defined. We examined the urinary biochemistry of patients taking magnesium supplementation with meals versus while fasting.

Materials And Methods: This was a single-institution, prospective, randomized controlled pilot study examining magnesium supplementation taken with meals versus while fasting in patients with a history of calcium oxalate stones and isolated hyperoxaluria.

External validation of a nomogram for outcome prediction in management of medium-sized (1-2 cm) kidney stones.

Background: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation.

Who Are the Mentors of the Future Endourologist? An Analysis of Endourological Society Program Directors.

Surgical training programs are pivotal in shaping skilled and compassionate surgeons, with mentors playing a crucial role in instilling clinical competence and essential attributes. This study aims to describe the characteristics of the program directors of Endourological Society-accredited fellowship programs. The Endourological Society's website was used to identify program directors.

Patient Safety and Quality Improvement in Minimally Invasive Surgery.

The journey of minimally invasive (MI) urology is one of quality improvement (QI) and patient safety. New techniques have been progressively studied for adoption and growth. As more advanced methods of data collection and analysis are developed, a review of the patterns and history of these principles in the development of MI urology can inform future urologic QI and patient safety initiatives.

The Impact of Bilateral Stone Disease on Patients' Disease Progression and Health-Related Quality of Life.

Patients with recurring kidney stone events can expect significant morbidity and functional impairment. Few studies have evaluated the effect of bilateral kidney stones on disease progression and quality of life. We wanted to determine the association of bilateral stone disease on age of onset, and the impact on number of stone events and individual kidney stone disease-specific health-related quality of life (HRQOL) by analyzing the validated and prospectively collected Wisconsin Stone Quality of Life (WISQOL) database.

The Endourological Society Inaugural Census Report.

The Endourological Society, the premier urologic society encompassing endourology, robotics, and focal surgery, is composed of a diverse group of >1300 urologists. However, limited information has been collected about society members. Recognizing this need, a survey was initiated to capture data regarding current member practices, as well as help the Society shape the future direction of the organization.

The Duration of Stone Disease and the Impact of a Stone Event on Patients' Quality of Life.

With a 5-year stone recurrence rate of 30% to 50%, kidney stone formers are subject to significant morbidity that negatively impacts their health-related quality of life (HRQOL). We sought to determine the impact of age at kidney stone onset, duration of stone disease, and kidney stone event (surgery or stone passage) on HRQOL of individual patients by querying the validated and prospectively collected Wisconsin Stone Quality of Life (WISQOL) database. Cross-sectional data were obtained from a total of 2438 kidney stone formers from 14 institutions in North America who completed the WISQOL questionnaire during the period from 2014 to 2019.

Evaluation of a Virtual Reality Percutaneous Nephrolithotomy (PCNL) Surgical Simulator.

Percutaneous Nephrolithotomy is the standard surgical procedure used to remove large kidney stones. PCNL procedures have a steep learning curve; a physician needs to complete between 36 and 60 procedures, to achieve clinical proficiency. Marion Surgical K181 is a virtual reality surgical simulator, which emulates the PCNL procedures without compromising the well-being of patients.

Estimating the health-related quality of life of kidney stone patients: initial results from the Wisconsin Stone Quality of Life Machine-Learning Algorithm (WISQOL-MLA).

Objective: To build the Wisconsin Stone Quality of Life Machine-Learning Algorithm (WISQOL-MLA) to predict urolithiasis patients' health-related quality of life (HRQoL) based on demographic, symptomatic and clinical data collected for the validation of the Wisconsin Stone Quality-of-Life (WISQOL) questionnaire, an HRQoL measurement tool designed specifically for patients with kidney stones.

Material And Methods: We used data from 3206 stone patients from 16 centres. We used gradient-boosting and deep-learning models to predict HRQoL scores.

Opioid Stewardship in Urology: Quality Improvement Summit 2018.

Introduction: We summarize the 2018 AUA (American Urological Association) Quality Improvement Summit, highlighting appropriate urological opioid use as well as reviewing programs that have been successful in reducing opioid prescribing. The AUA brought together nearly 100 attendees from across the United States, including clinicians who specialize in urology and other specialties, as well as researchers, government officials and others.

Methods: The 2018 AUA Quality Improvement Summit was a 1-day meeting held at AUA headquarters in Linthicum, Maryland.

Metabolic Syndrome Negatively Impacts Stone-Specific Quality of Life.

Metabolic syndrome (MetS) is a cluster of metabolic diseases that is linked to atherosclerotic cardiovascular disease. MetS has also been linked to increased nephrolithiasis. However, limited research has been conducted on MetS and its impact on stone-specific health-related quality of life (HRQOL).

The effect of travel distance on health-related quality of life for patients with nephrolithiasis.

Introduction: Urolithiasis causes a significant impact on health-related quality of life (HRQOL). Patients with kidney stones have high levels of stress and anxiety. Symptom resolution often requires treatment.
