Comparison of 24-hour urine composition prior to and after stone removal in nephrolithiasis: a prospective observational study.

Background: To evaluate 24-hour urine composition prior to and after complete stone removal in nephrolithiasis patients to determine potential relationship between kidney stones and patient metabolic status.

Methods: A prospective observational study was performed with patient enrollment from March 2019 to August 2020. 24-hour urine samples were collected prior to stone removal and 4 weeks after double-J stent removal, and examined the following urinary parameters: volume, creatinine, sodium, calcium, uric acid, citrate, oxalate, potassium, phosphorous, magnesium, and pH value.

Alteration of the gut microbiota by vinegar is associated with amelioration of hyperoxaluria-induced kidney injury.

Hyperoxaluria is well known to cause renal injury and end-stage kidney disease. Previous studies suggested that the renal function of rats with hyperoxaluria was improved after dietary vinegar intake. However, its underlying mechanisms remain largely unknown.

Dietary vinegar prevents kidney stone recurrence via epigenetic regulations.

Background: Epidemiological evidence of over 9000 people suggests that daily intake of vinegar whose principal bioactive component is acetic acid is associated with a reduced risk of nephrolithiasis. The underlying mechanism, however, remains largely unknown.

Methods: We examined the in vitro and in vivo anti-nephrolithiasis effects of vinegar and acetate.

A prospective and randomised trial comparing fluoroscopic, total ultrasonographic, and combined guidance for renal access in mini-percutaneous nephrolithotomy.

Objective: To compare the safety and efficacy of fluoroscopic guidance (FG), total ultrasonographic guidance (USG), and combined ultrasonographic and fluoroscopic guidance (CG) for percutaneous renal access in mini-percutaneous nephrolithotomy (mini-PCNL).

Patients And Methods: The present study was conducted between July 2014 and May 2015 as a prospective randomised trial at the First Affiliated Hospital of Guangzhou Medical University. In all, 450 consecutive patients with renal stones of >2 cm were randomised to undergo FG, USG, or CG mini-PCNL (150 patients for each group).
