Micro-percutaneous nephrolithotomy in infants: a single-center experience
Urolithiasis - - 2015
This study aimed to investigate the effectiveness and reliability of micro-percutaneous nephrolithotomy (micro-PNL) for the management of kidney stones in pediatric patients. This retrospective study included 24 infants that underwent micro-PNL for renal stones between March 2012 and April 2015. The inclusion criteria included: age younger than 2 years, stone size <20 mm, absence of urinary tract ......
Volume should be used instead of diameter for kidney stones between 10 and 20 mm to determine the type of surgery and increase success

The impact of ureteral stent indwelling time on the treatment of acute infection caused by ureteral calculi
Urolithiasis - Tập 45 - Trang 579-583 - 2017
Ureteric stenting is an effective drainage method in patients with acute urinary tract infection caused by ureteral calculi; however, the optimal ureteral stent indwelling time has not been clearly defined. The aim of this study was to evaluate the effect of ureteric stent indwelling time on the treatment of acute infection secondary to urinary tract calculi. A total of 142 patients with acute inf......
Determination of urinary lithogenic parameters in murine models orthologous to autosomal dominant polycystic kidney disease
Urolithiasis - Tập 42 - Trang 301-307 - 2014
Autosomal dominant polycystic kidney disease (ADPKD), a genetic disease caused by mutations in PKD1 or PKD2 genes, is associated with a high prevalence of nephrolithiasis. The underlying mechanisms may encompass structural abnormalities resulting from cyst growth, urinary metabolic abnormalities or both. An increased frequency of hypocitraturia has been described in ADPKD even in the absence of ne......
High ambient temperature impact on the pattern of emergency-room visits due to renal colic in the Middle East
Urolithiasis - - 2024
Urolithiasis has a seasonal pattern, with an established increase in incidence during the summer months. This study aims to assess the impact of high ambient temperatures on emergency room (ER) visits related to renal colic (RC) in a Middle Eastern country over the past decade. Population data were extracted using the MDClone Big Data platform. We recorded demographic and clinical data on all RC-a......
Getting hot in here! Comparison of Holmium vs. thulium laser in an anatomic hydrogel kidney model
Urolithiasis - - 2024
As laser technology has advanced, high-power lasers have become increasingly common. The Holmium: yttrium–aluminum-garnet (Ho:YAG) laser has long been accepted as the standard for laser lithotripsy. The thulium fiber laser (TFL) has recently been established as a viable option. The aim of this study is to evaluate thermal dose and temperature for the Ho:YAG laser to the TFL at four different laser......
Biochemical and dietary factors of uric acid stone formation
Urolithiasis - Tập 46 - Trang 167-172 - 2017
The aim of this study was to compare the clinical characteristics of “pure” uric acid renal stone formers (UA-RSFs) with that of mixed uric acid/calcium oxalate stone formers (UC-RSFs) and to identify which urinary and dietary risk factors predispose to their formation. A total of 136 UA-RSFs and 115 UC-RSFs were extracted from our database of renal stone formers. A control group of 60 subjects wi......
Geographic location is an important determinant of risk factors for stone disease
Urolithiasis - Tập 45 - Trang 429-433 - 2016
Some regions are known to have an increased burden of urolithiasis. Urolithiasis is known to be affected by weather patterns, particularly high ambient temperatures. To identify geographic differences in risk factors, we compared metabolic information for 1254 patients in two geographically distinct regions, New York and Florida, with per sample adjustment for ambient weather. We observed that pat......
Urinary supersaturation in a Randomized trial among Individuals with Nephrolithiasis comparing Empiric versus selective therapy (URINE): design and rationale of a clinical trial
Urolithiasis - Tập 51 - Trang 1-10 - 2023
Clinical guidelines disagree on whether the identification of abnormal urine chemistries should occur before starting diet and medication interventions to prevent the recurrence of kidney stone events. We describe the rationale and design of the Urinary supersaturation in a Randomized trial among Individuals with Nephrolithiasis comparing Empiric versus selective therapy (URINE) study, a randomize......
Determinants of ureteral obstruction after percutaneous nephrolithotomyAbstract Background Ureteral obstruction after percutaneous nephrolithotomy (PCNL) may require prolonged drainage with a nephrostomy tube (NT) or ureteral stent, but it is not well understood how and why this occurs. The goal of this study was to identify risk factors associated with postoperative ureteral obstruction to help guide ...
