ros and urolithiasis

Ercan Yuvanc, Erdal Yilmaz, Devrim Tuglu, Ertan Batislam
Nephrolithiasis is a serious problem for both patients and the health system. Recurrence stands out as a significant problem in urinary system stone disease, the prevalence of which is increasing gradually. If recurrence is not prevented, patients may go through recurrent operations due to nephrolithiasis. While classical therapeutic options are available for all stone types, the number of randomized controlled studies and extensive meta-analyses focusing on their efficiency are inadequate. Various alternative therapeutic options to these medical therapies also stand out in recent years...

BACKGROUND: Percutaneous nephrolithotripsy (PCNL) is one of the main interventional treatment modalities for large kidney stones (> 2 cm diameter). With the implementation of miniaturised techniques the indications for PCNL have been broadened to smaller stones. Especially for urologists without emphasis on endourology it is difficult to have an overview of the growing multitude of available systems and techniques. This article describes the currently available systems for percutaneous stone treatment with their peculiarities and indications...

Urolithiasis is a common disease of the urinary system. Extracorporeal shockwave lithotripsy (SWL) has become one of the standard treatments for renal and ureteral stones; however, the success rates range widely and failure of stone disintegration may cause additional outlay, alternative procedures, and even complications. We used the data available from noncontrast abdominal computed tomography (NCCT) to evaluate the impact of stone parameters and abdominal fat distribution on calculus-free rates following SWL...

Functioning of the hypothalamic-neurohypophyseal-vasopressin axis is altered in aging, and the pathway may represent a plausible target to slow the process of aging. Arginine vasopressin, a nine-amino acid peptide that is secreted from the posterior pituitary in response to high plasma osmolality and hypotension, is central in this pathway. Vasopressin has important roles in circulatory and water homoeostasis mediated by vasopressin receptor subtypes V1a (vascular), V1b (pituitary), and V2 (vascular, renal)...

Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over...

PURPOSE: The aim of this study was to assess the association between metabolic syndrome (MetS) and urolithiasis. BACKGROUND: Observational studies and reviews suggest an association between the incidence of urolithiasis and the prevalence of MetS. However, individual studies are needed to be gathered to come to a more reliable and precise conclusion. METHODS: We searched the Pubmed-Medline and Embase databases up to February 2014 to identify studies related to urolithiasis and metabolic syndrome...

PURPOSE: Contemporary predictive tools for percutaneous nephrolithotomy outcomes include the Guy stone score, S.T.O.N.E. nephrolithometry and the CROES nephrolithometric nomogram. We compared each scoring system in the same cohort to determine which was most predictive of surgical outcomes. METHODS: We retrospectively reviewed the records of patients who underwent percutaneous nephrolithotomy between 2009 and 2012 at a total of 3 academic institutions. We calculated the Guy stone score, the S...

The incidence of pediatric stone disease has been increasing. Though there are geographical variations, there remains a common theme in that this is a high-risk population with regard to stone formation and recurrence. Consequently, it is important to keep the number of procedures performed to a minimum and to save the developing kidney from the deleterious effects of intervention. Of the number of available treatment options, Percutaneous Nephrolithotomy (PCNL) offers a number of distinct advantages albeit with its own set of concerns...

Idiopathic hypercalciuria (IH) is the leading metabolic risk factor for urolithiasis and affects all age groups without gender or race predominance. IH has a high morbidity with or without lithiasis and reduced bone mineral density (BMD), as described previously in pediatric patients as well as in adults. The pathogenesis of IH is complex and not completely understood, given that urinary excretion of calcium is the end result of an interplay between three organs (gut, bone and kidney), which is further orchestrated by hormones, such as 1,25 dihydroxyvitamin D, parathyroid hormone, calcitonin and fosfatonins (i...

INTRODUCTION: Twenty-five years of SMIT represents an important date. In this article we want to elaborate the development of minimally invasive surgery in urology during the last three decades and try to look 25 years ahead. MATERIAL AND METHODS: As classical scenarios to demonstrate the changes which have revolutionized surgical treatment in urology, we have selected the management of urolithiasis, renal tumour, and localized prostate cancer. This was based on personal experience and a review of the recent literature on MIS in Urology on a MEDLINE/PUBMED research...

We are often told that we should be drinking more water, but the rationale for this remains unclear and no recommendations currently exist for a healthy fluid intake supported by rigorous scientific evidence. Crucially, the same lack of evidence precludes the claim that a high fluid intake has no clinical benefit. The aim of this study is to describe the mechanisms by which chronic low fluid intake may play a crucial role in the pathologies of four key diseases of the urinary system: urolithiasis, urinary tract infection, chronic kidney disease and bladder cancer...

PURPOSE: There is a lack of information on the safety and efficacy of ureteroscopy in the neurogenic bladder population. We hypothesized that ureteroscopy in patients with neurogenic bladder would be associated with an increased risk of complications and a lower stone clearance rate than in patients without neurological impairment. MATERIALS AND METHODS: We reviewed a local registry of patients with ICD-9 codes for urolithiasis between 2004 and 2012. The study cohort was assembled from all eligible patients with neurogenic bladder and a randomly selected control group that had undergone ureteroscopy...

PURPOSE OF REVIEW: Over the past 10 years, we have seen major advances in urological imaging including developments in digital imaging, ultrasound and computerized tomography (CT) scanning. All of these have had an impact on the management of urinary tract stone disease. In parallel with these, we have witnessed a greater appreciation of the potential harm of irradiation exposure. In this article, we aim to provide an overview of the impact of imaging in urolithiasis treatment planning in 2013...

PURPOSE: We have evaluated the clinical, radiological and metabolic features of infantile urolithiasis (UL). MATERIALS AND METHODS: We have reviewed the medical records of 93 children who were diagnosed as having UL before 1 year of age. We recorded patient demographics, the age at diagnosis, presenting symptoms, family history, the localizations and dimensions of stones, urinary metabolic examinations, as well as physical, laboratory, and radiologic findings. Our secondary objective was to compare some features of this group with those of older children with UL followed-up in the same clinic which were previously reported...

AIM: To investigate the impact of statin medications on urinary stone formation in hyperlipidemic patients. MATERIAL AND METHODS: We searched outpatient military electronic health records from the Southwestern United States to identify adult patients with hyperlipidemia and urolithiasis. Military facilities serve active duty members, retirees, and their immediate family members. We created two predictor variables - with and without statin. The outcome variable was a diagnosis of urolithiasis...

Urolithiasis is a relevant clinical problem with a subsequent burden for health system. The aim of this review is to provide recent progress made using genetic polymorphisms to define pathophysiology, to identify persons at risk for kidney stone disease and to predict treatment response. Population case-control studies are useful both as an alternative and an adjunct as compared to family studies. These involve either whole genome scanning or candidate gene approaches. While whole genome scanning is likely to be widely used in future, at present, candidate gene studies are more feasible...

BACKGROUND AND PURPOSE: Patients with spinal neuropathy are at an increased risk for urolithiasis. Data on percutaneous nephrolithotomy (PCNL) in this population are limited. Our objective is to review our experience in managing stones with PCNL in patients with spinal neuropathy. PATIENTS AND METHODS: Twenty-one patients with spinal neuropathy underwent PCNL at our institution between January 2005 and August 2011. Their medical records were reviewed retrospectively to collect data relating to stone characteristics, treatment outcomes, and complications...
