Article Abstract
Objective: To present the most recent data on urinary calculi characteristics in the southern region of China and explore the effects of sociodemographic, clinical and laboratory characteristics on stone composition to fill the research gap.
Setting: A retrospective observational study was performed in Shenzhen between December 2019 and August 2022.
Participants: A total of 858 calculi samples from patients with urolithiasis were analysed via infrared spectroscopy.
Methods: The stone was classified by the European Association of Urology guidelines and the Mayo Clinic stone classification practices. Multivariate logistic regression models were conducted to evaluate the association between different characteristics and urinary stone composition.
Results: We found that the majority of these patients with urolithiasis were under 60. Almost half of the stone samples (49.4%) were single constitute, and calcium oxalate stone accounted for the highest proportion (80.0%), followed by infection stone (10.0%) and uric acid stone (4.9%). Of these, 78.0% were collected from males, with a male-to-female ratio of 3.54:1; the majority (95.0%) of calculi localisation was in the upper urinary tract. Multivariate analysis found that age, gender, history of urolithiasis, kidney disease, anatomical location and urinary pH influenced urinary stone composition.
Conclusions: The effective prevention of urolithiasis is the key to this working-age population. These findings may supply significant evidence for understanding the underlying aetiology of urolithiasis and offer clues for effectively preventing and treating urinary calculi.

Objectives: Urinary calculi are characterized by a high recurrence rate, and patients' adherence to self-management after discharge directly affects health outcomes. Traditional offline follow-up models often face problems such as poor compliance and uneven allocation of medical resources, making it difficult to meet individualized health management needs. Remote follow-up provides a novel solution to optimize long-term management, improve health literacy, and enhance clinical outcomes.

Kidney stones have a high recurrence rate-10% within 5 years and 50% within 10. Crystalluria reflects the urinary physicochemical environment and may serve as a recurrence marker, but key crystals like brushite are rarely detected under ambient conditions. This study aimed to identify novel recurrence markers by inducing crystallization through urine cooling and analyzing crystal composition.

Background: Kidney stone formation is driven by an imbalance between lithogenic substances and crystallization inhibitors. Current guidelines recommend a 24-h urine collection in patients with kidney stone disease to assess the risk of stone formation and monitor therapy compliance. However, real-world data on adherence to these guidelines remain limited and outdated.

Objectives: To report outcomes of complete ultrasound-guided percutaneous nephrolithotomy (PCNL) for horseshoe kidney (HSK) stones at a high-volume center and evaluate a novel technique (Needle-perc-assisted endoscopic surgery, NAES) for these patients.
Patients And Methods: We retrospectively reviewed all HSK stone patients who underwent PCNL at our institution over a 10-year period. The NAES technique was utilized during the most recent 4 years.
