Metabolic dysfunction-associated fatty liver disease as a mediator of urolithiasis risk: evidence from cross-sectional and genetic studies.

The rising prevalence of urolithiasis and metabolic dysfunction-associated fatty liver disease (MAFLD) has become a significant concern within urology and hepatology, respectively. Emerging studies reveal a compelling association between these conditions, yet the underlying relationship remains poorly understood. This study aims to investigate the connection between urolithiasis and MAFLD within the Chinese population and leverages Mendelian Randomization (MR) analysis to explore potential causal links between the two diseases, shedding light on new avenues for both prevention and treatment.

The diagnostic performance of indocyanine green for the sentinel node biopsy in prostate cancer: A systematic review and meta-analysis.

Objective: Almost 15% of prostate cancer (PCa) patients were found to have lymph node metastases (LNMs), which are associated with higher risk of biochemical recurrence. Using indocyanine green (ICG) for the sentinel node biopsy (SNB) before surgery was proposed to detect LNMs in PCa patients. However, its diagnostic performance still remains controversial.

A comparison of male and female renal pelvis urobiome of unilateral stone formers using 2bRAD-M.

Background: Urolithiasis is a prevalent urological ailment characterized by increasing prevalence and recurrence rates, resulting in substantial social and economic burden. While men exhibit an incidence rate nearly twice that of women, this gender disparity is gradually diminishing. Nevertheless, the mechanisms underlying this condition remain incompletely elucidated.

The Involvement of Endoplasmic Reticulum Stress during the Interaction between Calcium Oxalate Crystals and Renal Tubular Epithelial Cells.

Our study aimed to elucidate the mechanisms behind the interaction between calcium oxalate (CaOx) crystals and renal tubular epithelial cells through transcriptome sequencing analysis. HK-2 cells were stimulated with or without CaOx monohydrate crystals and subjected to RNA-seq to assess the effects of CaOx crystals on gene expression changes, key pathways, and molecular players during this interaction. A total of 629 differentially expressed genes (DEGs) were identified between the control group and experimental group, with 491 genes up-regulated and 138 down-regulated.

The genetics of urinary microbiome, an exploration of the trigger in calcium oxalate stone.

Kidney stone disease is a global disease; however, it has not been totally understood. Calcium oxalate (CaOx) stone is the dominant type of kidney stone, and the potential factors involved in its formation are yet to be explored. Clinically, we found that the CaOx stones in patients were mainly unilateral; therefore, systemic factors cannot explain them, although some local factors must be involved.

Exosome, the glass slipper for Cinderella of cancer-bladder cancer?

Exosomes are lipid bilayer vesicles with a diameter of 40-100 nm secreted by almost all cells. They have been found play crucial regulatory roles in various diseases. With the development of exosomes engineering technology, exosome-based drug delivery has also rapidly evolved.

Identification of Two Clusters in Renal Pelvis Urobiome of Unilateral Stone Formers Using 2bRAD-M.

Urolithiasis is a common urological disease with increasing incidence and a high recurrence rate, whose etiology is not fully understood. The application of sequencing and culturomics has revealed that urolithiasis is closely related to the urinary microbiome (urobiome), shedding new light on the pathogenesis of stone formation. In this study, we recruited 30 patients with unilateral stones and collected their renal pelvis urine from both sides.

Interconnections between urolithiasis and oral health: a cross-sectional and bidirectional Mendelian randomization study.

Introduction: Urolithiasis is one of the most common diseases for urologists and it is a heavy burden for stone formers and society. The theory of the oral-genitourinary axis casts novel light on the pathological process of genitourinary system diseases. Hence, we performed this study to characterize the crosstalk between oral health conditions and urolithiasis to provide evidence for prevention measures and mechanisms of stone formation.
