Stone Disease

Predictive factors of stone-free rate and complications in patients with proximal impacted ureteral stones undergoing percutaneous nephrolithotomy: based on a new scoring standard.

To evaluate the predictive factors affecting the stone-free rate (SFR) and complications of percutaneous nephrolithotomy (PCN) in the treatment of proximal impacted ureteral stones (PIUS) based on a new scoring standard.

Association between remnant cholesterol and risk of kidney stones: a case-control study in Chinese adults.

Remnant cholesterol (RC), a key indicator of dyslipidemia, has been validated as a contributing factor to metabolic and cardiovascular diseases, both of which are closely associated with kidney stones (KS).

Polish validation of the wisconsin stone quality of life questionnaire (POL-WISQoL).

Urolithiasis significantly affects patient quality of life, yet the global standard of care predominantly focuses on achieving a stone free status, often ignoring patient reported outcomes. Currently, there are no specific measures available to assess the quality of life in the Polish population suffering from kidney stones.

Association between cardiometabolic index and kidney stone from NHANES: a population-based study.

The Cardiometabolic Index (CMI) is a novel marker of visceral obesity and dyslipidemia. Our study aimed to explore the association between CMI and kidney stones among US adults.

This cross-sectional study was conducted among adults with complete records of CMI and kidney stones information from the 2011 to 2018 National Health and Nutrition Examination Survey (NHANES).

SGLT2 Inhibitors and Their Effect on Urolithiasis: Current Evidence and Future Directions.

Urolithiasis (UL) is increasingly prevalent due to rising cardiorenometabolic diseases, posing significant management challenges despite advances in urological techniques. Sodium-glucose cotransporter-2 (SGLT2) inhibitors, primarily used for type 2 diabetes mellitus, chronic kidney disease, and heart failure, have emerged as a potential novel approach for UL treatment.

Assessing the safety of ureteral stent placement for obstructive urolithiasis in patients during the COVID-19 pandemic.

Patients with an active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [coronavirus disease 2019 (COVID-19)] infection are at a higher risk of post-operative mortality. In this retrospective case-control study, we analyzed the post-operative safety of patients undergoing cystoscopy with ureteral stent placement for obstructing ureteral calculi who tested positive for COVID-19.

Factors affecting radiation exposure in patients undergoing endoscopic treatment for urolithiasis.

Imaging techniques, such as computed tomography (CT) and fluoroscopy, are essential for the diagnosis and treatment of urolithiasis. There is increasing concern regarding the cumulative radiation dose associated with medical imaging and its adverse effects.

Suction use in ureterorenoscopy: A systematic review and meta-analysis of comparative studies.

Ureterorenoscopy is seeing a bloom of technological advances, one of which is incorporating suction. The objective of this study is to systematically review existing literature regarding suction use in rigid and flexible ureterorenoscopy and perform meta-analysis of studies comparing suction versus no suction ureteroscopy or mini percutaneous nephrolithotomy (PCNL).

Metabolic Evaluation and Recurrence Prevention for Urinary Stone Patients: An EAU Guidelines Update

Background and objective: The aim of this review was to define patients who are at high risk of recurrence of urolithiasis, to delineate diagnostic and therapeutic algorithms for each type of stone, and to clarify general guidelines and recommendations for prevention of recurrence.

Methods: A professional research librarian carried out literature searches for all sections of the urolithiasis guidelines, covering the timeframe between 1976 and June 2023.

Key findings and limitations: For every patient with urolithiasis, an attempt should be made to analyse the stone. Patients should be given general instructions on how to prevent recurrence, including adequate fluid and calcium intake, and low consumption of sodium and protein. Identifying and correcting the causative factors is a cornerstone
in preventing the recurrence of urolithiasis. Diagnostic and therapeutic algorithms by stone composition are available. Every patient should undergo baseline metabolic screening, while patients with calcium stones, who are at high risk of relapse and complications, should undergo extensive metabolic screening with two 24-h urine collections and should receive targeted therapy. Patients with uric acid, infection, or cystine stones are at high risk of relapse. All patients at high risk of recurrence should be closely monitored, especially those not complying with therapy in the long term.

Conclusions and clinical implications: Metabolic stone evaluation and patient follow-up are highly recommended to prevent urolithiasis recurrence.

Is double-J stent mandatory in complete supine percutaneous nephrolithotomy for adult patients with staghorn renal stones?

It is controversial whether double-J (DJ) stent insertion is necessary in tubeless percutaneous nephrolithotomy (PCNL) for patients with staghorn stones. We compared the outcomes of using ureteral catheters and double-J stents in tubeless complete supine PCNL (csPCNL) of staghorn stones.
