Urolithiasis Articles

Urolithiasis represents the most frequent complication of horseshoe kidneys. All known approaches for stone disease management have been reported in these patients, including Extracorporeal Shockwave Lithotripsy, ureteroscopy, Percutaneous Nephrolithotomy, open surgery and laparoscopy.

The article describes a clinical case of kidney stone disease (KSD) in a child of 4 y.o. with calcium urolithiasis. Analysis of chemical content of the kidney stones revealed their calcium-oxalate composition.

Kidney stone disease has become an important worldwide socioeconomic issue. However, metaphylaxis fails due to low compliance rates. Therefore, we developed a mobile app (StoneMD: Kidney Stones) for patients with kidney stones to increase compliance in stone metaphylaxis.

There are more than 20 drugs, that are widely used as medical expulsive therapy after extracorporeal shock wave lithotripsy (ESWL). Herbal plants are actively used along with the drug therapy in order to improve the efficiency of the treatment.

Urolithiasis is a common disease, and is an important health problem that is associated with a great economic burden. The nature of stone disease varies according by dietary and lifestyle factors, including, among others, climate variations.

Along with an increase in the worldwide prevalence of renal tumors and urolithiasis, recently there has been a clear tendency for co-occurrence of the two diseases. An analysis of the literature has revealed several unresolved issues, including the identification of the causal link between the two diseases and determination of rational therapies for their combination, which necessitates a careful investigation of the problem.

Nephrolithiasis is a highly prevalent disease presenting itself mostly at a working age, which leads to a great economic burden on health system. Kidney Stone disease should be viewed as a systemic disorder,associated with or predictive of hypertension, insulin resistance, chronic kidney disease and cardiovasculardamage.

Kidney stone disease (KSD) is an actual problem of modern health care. By now, more than 80 monogenic forms of urolithiasis have been described. To diagnose such forms of KSD different molecular genetic technologies are used.

Dietary supplements are successfully used in many fields of medicine, including urology. In particular, urologists often prescribe dietary supplements for patients with urolithiasis.

to study an influence of dietary supplements Nefradoz on the metabolism of the main stone-forming substances and inhibitors of stone formation in patients with urolithiasis.

To obtain the information about functional state of kidneys in patients with urolithiasis before and after treatment, as well as to study the damaging effect of different types of energy used for fragmentation of high-density stones.

To assess the efficacy and morbidity of percutaneous nephrolithotomy (PNLT) in the treatment of renal stones in patients with neurogenic lower urinary tract dysfunction (NLUTD).

Retrospective, monocentric study including all patients with NLUTD who had undergone PNLT between 2005 and 2017.

Urinary tract infection (UTI) are a risk factor for diseases leading to impairment of renal function and kidney stone disease (KSD). Growing resistance of uropathogens to antibacterial agents is a challenging issue in most countries of the world.

Urolithiasis in a kidney transplanted patient is an uncommon but complex urological complication. Its potential severity comes from its occurrence on a solitary kidney and on a field of immunosuppression.

ORLANDO, FL USA (UroToday.com) - Presented by Margaret S. Pearle, MD, PhD, on behalf of the MMKS Guideline Panel* at the American Urological Association (AUA) Annual Meeting - May 16 - 21, 2014 - Orlando, Florida USA

Specific factors associated with the risk of developing pediatric urinary stone disease remain unclear, especially those that may be associated with recurrent stone disease.

We compared the results of 24-h urine collections in children with a solitary stone episode to those with multiple stone episodes to determine if there is a difference that may be associated with multiple stone formation in children.

The present retrospective study on urinary stone disease in the Uttarakhand state was necessitated as no study has been done yet.

A 13 year retrospective study (from 2005 to 2018) was conducted on the urinary stones removed from the patients, admitted at Himalayan Institute of Medical Sciences, Dehradun.

Introduction: Recent decades have seen a move to minimally invasive techniques to manage urolithiasis. Trainees are expected to develop competency in common endourology procedures. Knowledge of ureter mechanics and the theory behind new technologies is important to ensure safe and efficient techniques.

With the rise in the use of ureteroscopy and laser stone lithotripsy (URSL), a proportionate increase in the risk of post-procedural urosepsis has also been observed. The aims of our paper were to analyse the predictors for severe urosepsis using a machine learning model (ML) in patients that needed intensive care unit (ICU) admission and to make comparisons with a matched cohort.

Urolithiasis is a common urological disease, and treatment strategy options vary between different stone types. However, accurate detection of stone composition can only be performed in vitro. The management of infection stones is particularly challenging with yet no effective approach to pre-operatively identify infection stones from non-infection stones.

Urinary stone disease is a widespread disease with tremendous impact on those affected and on societies around the globe. Nevertheless, clinical and health care research in this area seem to lag far behind cardiovascular diseases or cancer.

Currently an evidence-based approach to nephrolithiasis is hampered by a lack of randomized controlled trials. Thus, there is a need for common platforms for data sharing and recruitment of patients to interventional studies.

Association of increased oxidative stress (OS) with the pathophysiology of renal stone formation has not been explored greatly in the field of urolithiasis. In this prospective case-control study, we measured 24-h urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels in patients with urolithiasis and compared them with matched healthy controls.

Urolithiasis is considered a vital public health issue with a substantial burden on kidney function. Additionally, only few reports focused on the gender difference in patients with urolithiasis. Therefore, this study aimed to compare the clinical characteristics of sex difference and their potential risk for chronic kidney disease (CKD) in patients with urolithiasis.

Preoperative diagnosis of urinary infection stones is difficult, and accurate detection of stone composition can only be performed ex vivo. To provide guidance for better perioperative management and postoperative prevention of infection stones, we developed a machine learning model for preoperative identification of infection stones in vivo.

Nomograms, used to predict the risk and success of treatment of urinary tract stones, are being used in paediatric clinical practice. However, no studies have determined the best prediction model. This study aimed to identify the most robust nomogram(s) for predicting clinically relevant outcomes in urinary stone disease in paediatric patients.

Oral chemolysis is an effective and non-invasive treatment for uric acid urinary stones. This study aimed to classify urinary stones into either pure uric acid (pUA) or other composition (Others) using non-contrast-enhanced computed tomography scans (NCCTs).

Noncontrast CT (NCCT) is the imaging study of choice for initial evaluation of patients with acute onset of flank pain and suspicion of stone disease without known prior stone disease. NCCT can reliably characterize the location and size of an offending ureteral calculus, identify complications, and diagnose alternative etiologies of abdominal pain.

Bacterial infection has long been recognized to contribute to struvite urinary stone deposition; however, its contribution to the development of chronic kidney stones has not been extensively investigated.

To evaluate the effect of learning curve on supine mini-percutaneous nephrolithotomy (PNL) outcomes.

The aim of the study was to include a total of 75 patients. All of the patients were operated on by the same team, which had experience of at least 100 prone mini-PNL cases.

Ureteroscopy is increasingly being used for urolithiasis. Technological innovations have been accompanied by wide variations in practice patterns. At the same time, a common finding in many studies, especially systematic reviews, is that the heterogeneity of outcome measurements and lack of standardisation can limit both the reproducibility and generalisability of study findings.

Urolithiasis has become increasingly prevalent, leading to higher disability-adjusted life years and deaths. Various stone classification systems have been developed to enhance the understanding of lithogenesis, aid urologists in treatment decisions, and predict recurrence risk.

Urolithiasis is a common disease with increasing prevalence worldwide and a lifetime-estimated recurrence risk of over 50%. Imaging plays a critical role in the initial diagnosis, follow-up and urological management of urinary tract stone disease.

Background: The ureteral access sheath (UAS) has revolutionized the management of urinary pathology in the upper tract by providing rapid repeatable access to the upper urinary tract. However, in many practices, it remains a controversial tool in endourology given concerns of possible ureteral injury and presumed long-term sequela from those injuries.

Urolithiasis is one of the most common diseases of the urinary system, the incidence of which is assumed to be up to 100,000 cases per million (10% of the population). The cause of it is dysregulation of renal urine excretion.

Laser lithotripsy is gaining global prominence and is a dynamically progressing field marked by a continual influx of new and comprehensive research each year. Recently, there has been a noticeable shift toward the adoption of various kinds of lasers, such as holmium: yttrium-aluminum-garnet (Ho:YAG) and thulium fiber (TFL) lasers.

Endoscopic lithotripsy has become widely adopted worldwide and is considered the gold standard for managing upper urinary tract lithiasis. One of its possible complications is post-operative infection.

The intestinal microbiome may affect urinary stone disease by modulating the amount of oxalate absorbed from the intestine and subsequently excreted in urine. This study sought to explore the association between antibiotics, which alter the intestinal microbiota, and risk for urinary stone disease.

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.

Introduction: Artificial urinary calculi are an essential tool for research and training in endourology. The goal of the study was to evaluate different types of artificial stones and how they behave to laser treatment, to finally determine which is the optimal one for training purposes.

The causal relationship between alcohol and urolithiasis remains uncertain, despite previous observational studies reporting an association between the two. To determine the causality, we conducted a two-sample Mendelian randomization (MR) analysis.

To compare the risk of bladder cancer and bladder cancer mortality among patients with chronic bladder catheterisation (indwelling or intermittent) to patients from the general population.

Retrospective cohort study.

Studies on the impact of dietary fiber intake on kidney stones are few, and their results were controversial. This study aimed to explore the association between dietary fiber intake and kidney stones in the nationally representative population of the USA.

Given the risk factors for stone disease, it is possible that multiple chronic condition (MCC) patients are at increased risk of developing new, recurrent, or worsening urolithiasis. The purpose of our investigation was to evaluate the relationship between MCCs and urolithiasis.

The effect of obstructive sleep apnea (OSA) on 24-h urine parameters and resultant kidney stone risk is unknown. We sought to compare urinary lithogenic risk factors among patients with kidney stone disease with and without OSA.

Kidney stone formers have lower health-related quality of life (HRQOL) than non-stone formers. The North American Stone Quality of Life Consortium is a multi-center, longitudinal prospective study of kidney stone patients' HRQOL using the Wisconsin Stone Quality of Life questionnaire, with data currently collected on 2052 patients from 11 centers.

We aim to provide an up-to-date literature review to further characterise the association of kidney stone disease (KSD) with gastrointestinal (GI) surgery. As KSD is associated with significant morbidity, it is important to quantify and qualify this association to provide better care and management for the patient subgroup.

The AUA Medical Management of Kidney Stones guideline outlines recommendations on follow-up testing for patients prescribed preventive pharmacological therapy. We evaluated adherence to these recommendations by provider specialty.

Driven by expanding indications, topiramate and zonisamide utilization has increased over time. This trend may be associated with greater occurrence of kidney stones given the effects of these medications on urine chemistries.

Approximately 1 in 20 people develops kidney stones at some point in their life. Although the surgical removal of stones is common, the recurrence rate remains high and it is therefore important to prevent the occurrence of kidney stones.
