In the United States, urolithiasis affects approximately 1 in 11 people, and there is evidence that the prevalence is increasing. A relatively recent treatment strategy for urolithiasis involves using medical expulsive therapy (MET) to increase the likelihood of spontaneous passage of ureteral stones. The 2 leading drug classes for MET are alpha-1-andrenergic receptor blockers and calcium channel blockers. Tamsulosin, an alpha-1-adrenocepter blocking agent, is thought to induce spontaneous stone passage by relaxing ureteral smooth muscle tone...

BACKGROUND: Tumour markers are substances produced by the tumour itself, or by the host in response to a tumour. These markers could be measured either in the blood or in body secretions. One of the most common tumour markers used in gastrointestinal diseases is Ca 19-9. It is the marker most used for pancreatic cancer, but can be elevated in many benign processes. Thus, it is not a specific marker. CLINICAL CASE: The case is presented of a male patient with 4 years of moderate abdominal pain, weight loss, and persistent elevation of Ca 19-9...

INTRODUCTION: Urolithiasis is among the top 10 causes of Emergency Department (ED) visits in the United States. Approximately 50% of these patients undergo abdominopelvic CT scan, many more than once. We hypothesized that chronic pain conditions may contribute to frequent CT scans in patients who are evaluated in ED for urolithiasis. METHODS: A retrospective review of patients presenting to our tertiary care and the associated satellite EDs for urolithiasis, during the period 12/2012-05/2013, was performed...

Whether prevention of Urolithiasis is worthwhile is the outcome of the balance between efficacy of prevention and costs and efforts related of respectively prevention and treatment of a new stone. Well controlled trials demonstrate that effective prevention of new stone formation is possible using medical treatment and lifestyle interventions. In long-term general practice the results obtained with preventive interventions is disappointing. Low and diminishing long-term compliance to the intervention is a major cause for this...

The presence of fluoride ions in drinking water plays an important role in human health. For that reason, maintaining the optimum concentration of fluoride ions in drinking water is essential, as both low and excess (above the permissible level) concentrations can cause different health problems, such as fluorosis, urolithiasis, kidney failure, cancer, and can even lead to death. So, development of a simple and low cost method for the detection of fluoride ions in water is highly desirable. In this study, a fluorometric method based on Ag-CdS/Ag-ZnS core/shell nanoparticles is developed for fluoride ion detection...

OBJECTIVES: To review previous reports and discuss current trends in extracorporeal shockwave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL) and ureterorenoscopy (URS). ESWL was recommended as the first-line treatment for small and intermediate-sized stones in the lower pole, while it is the standard treatment for large stones. However, the stone clearance rate after ESWL seems to be lower than that of stones in other locations. This seems to result from a lower rate of fragment passage, due to anatomical factors...

OBJECTIVES: Urolithiasis is a considerable economic burden for health systems, especially in industrialised countries where the incidence of stone disease has increased during the last few decades, and probably will further increase for several reasons. METHODS: The survey was based on investigations in collaboration with a German health insurance company and on a literature search (PubMed, and the author's collection of proceedings of urolithiasis conferences: The keywords included economics, cost, urolithiasis, nephrolithiasis, renal stone disease, metaphylaxis, recurrence) during 1999-2011...

The frequency of stone disease in childhood ranges between 0.1-5 percent. Stone disease occurs as a result of enviromental, metabolic, anatomical, infectious and nutritional factors. Percutaneous nephrolitotomy, uretherorenoscopy, laparoscopic surgery, open surgery and extracorporeal shock wave lithothripsy are treatment alternatives for stone disease during childhood. However, these methods are not completely innocent. Some complications may occur after these procedures. These procedures are generally not cost- effective...

INTRODUCTION: The functioning of modern urological departments and the high level of service they provide is possible through, among other things, the use of modern laser techniques. MATERIAL AND METHODS: Open operations have been replaced by minimally invasive procedures, and classical surgical tools by advanced lasers. The search for new applications with lasers began as technology developed. Among many devices available, holmium, diode and thulium lasers are currently the most popular...

The paper describes for the first time the method of contact ureteral lithotripsy in gaseous (CO2) medium. It presents the results of a comparative study of urolithiasis patients treated with this treatment modality (study group, n=30) and with traditional contact ureteral lithotripsy in liquid medium (control group, n=30). The incidence of retrograde migration of calculus in the kidney in the study group was 0%, while it was 16.6% in the control group. Acute or exacerbation of chronic pyelonephritis was diagnosed in only 3 (10%) patients in the control group...

OBJECTIVE: The purpose of this study was to determine the cost-effectiveness of serial stenting vs ureteroscopy for treatment of urolithiasis during pregnancy as a function of gestational age (GA) at diagnosis. STUDY DESIGN: We built decision analytic models for a hypothetical cohort of pregnant women who had received a diagnosis of symptomatic ureteral calculi and compared serial stenting to ureteroscopy. We assumed ureteral stent replacement every 4 weeks during pregnancy, intravenous sedation for stent placement, and spinal anesthetic for ureteroscopy...

PURPOSE: Live related renal donors with urolithiasis are made suitable for renal transplantation in two-stage procedure in most of the centers: first making the donor kidney stone free surgically or by ESWL and then proceeding to renal transplantation. To reduce the cost and morbidity of two surgical procedures in donors, we did a pilot study of removing subcentimeter renal calculi in live donors, after explanting the kidney, during bench surgery. MATERIALS AND METHODS: We included all prospective renal donors with subcentimeter (4-10 mm) calculi in one kidney in our study (n = 14)...

BACKGROUND: Although renal colic in children in the United States remains relatively uncommon compared to in adults, its incidence has nearly doubled from 1999 to 2008. Noncontrast computed tomography (CT) is the current standard for the evaluation of suspected renal colic, given its high sensitivity and specificity. However, the greater lifetime risk of radiation-induced cancer from CT in pediatric patients has led to efforts to minimize radiation exposure. Additionally, pediatric renal colic is often recurrent, which might require multiple imaging studies during their lifetime...
