BACKGROUND: Urolithiasis is rare in pediatric patients. All patients with inflammatory bowel disease (IBD) have an increased risk of urolithiasis, but this risk is poorly quantified in children. The objective of this study is to evaluate the association of IBD with urolithiasis, assess surgical outcomes, and analyze the financial burden for children hospitalized with urolithiasis and comorbid IBD. METHODS: The triennial Healthcare Cost and Utilization Project Kids' Inpatient Database for years 1997 to 2012 was used to evaluate the association between urolithiasis and IBD in hospitalized, nonpregnant children ages 5 to 20 years old...

INTRODUCTION: Urolithiasis is a common medical condition that accounts for a large number of emergency department (ED) visits each year and contributes significantly to annual healthcare costs. Urinalysis is an important screening test for patients presenting with symptoms suspicious for urolithiasis. At present there is a paucity of medical literature examining the characteristics of ureteral stones in patients who have microscopic hematuria on urinalysis versus those who do not. The purpose of this study was to examine mean ureteral stone size and its relationship to the incidence of clinically significant hydronephrosis in patients with and without microscopic hematuria...

PURPOSE: Holmium:YAG laser is the most used laser for urolithiasis. Generally, we use metallic scissors to cut the fiber tip to restore its effectiveness. Many cleaving methods have been described to avoid fiber damage and to restore its greatest power to the fiber. There is a lack of information regarding which cleaving method should be used and its effect on the fiber. In order to compare these effects, we studied different cleavage methods in terms of power output and its effects on the fiber...

Background: Recurrent urolithiasis is troublesome for both patient and clinician, and in most cases, an underlying cause is not found. An important and underdiagnosed cause is adenine phosphoribosyltransferase (APRT) deficiency that gives rise to 2,8-dihydroxyadenine (2,8-DHA) stones. If diagnosed early, patient morbidity as well as the financial cost of treating stone recurrence can be avoided with simple medical therapy. Case Presentation: A 36-year-old white, Caucasian male with recurrent urolithiasis was found to have 2,8-DHA stones...

The prevalence of urinary stones in the United States has been described as 1 in 11 persons reporting a history of stones. Imaging plays a crucial role in diagnosis, management, and follow-up for these patients and imaging technology over the last 100 years has advanced as the disease prevalence has increased. CT remains the gold standard for imaging urolithiasis and changes in this technology, with the addition of multidetector CT and dual-energy CT, as well as the changes in utilization of CT, have decreased the radiation dose encountered by patients and allowed for improved stone detection...

BACKGROUND: Many surgeons use a stent after ureteroscopic lithotripsy (URSL). For short-term stenting purposes, a surgeon has the choice of either a tethered or a non-tethered stent. Stents may be associated with complications that entail an additional cost to their use. There is a paucity of data on the direct healthcare cost of using stent type after either primary or secondary URSL. METHODS: We retrospectively reviewed medical records for patients who underwent URSL for uncomplicated urolithiasis between January 2013 and December 2013 at two tertiary referral hospitals...

Urolithiasis is a common disease with increasing prevalence worldwide and a lifetimeestimated recurrence risk of over 50%. Imaging techniques play a critical role in the initial diagnosis, follow-up and urological management of urinary tract stone disease. The are many useful tools for diagnosing urolithiasis, including conventional plain radiography, intravenous urography, ultrasonography, computed tomography and magnetic resonance imaging. All these techniques have their own individual roles to play and also their limitations...

BACKGROUND: Most children with symptoms of urolithiasis and urinary solute excretion abnormalities leading to stone formation have no calculi revealed by ultrasound or X-ray plain film ("occult urolithiasis"). This covers a large group of children presenting with common symptoms such as abdominal pain, hematuria, and dysuria, often faced by general practitioners and pediatricians. However, half or more of children with urolithiasis could present with abdominal/flank pain without specific urinary symptoms...

PURPOSE: Recent reports support renal ultrasound as the initial imaging study to evaluate patients with suspected renal colic. However, urologists often advocate for computerized tomography to better define stone size and location, especially before proceeding with endourological intervention. One concern with using ultrasound as initial imaging is that computerized tomography may be required later, obviating the reduction in costs and radiation gained by using ultrasound. MATERIALS AND METHODS: We retrospectively reviewed the electronic health records of 10,680 episodes of stone disease in a total of 7,659 patients who presented to the emergency department or walk-in clinic with a chief complaint or visit diagnosis of urolithiasis from 2009 to 2015 at a single institution...

PURPOSE OF REVIEW: Flexible ureteroscopy has been widely developed in the last decade been nowadays one of the first line treatment options for urolithiasis and conservative management for upper tract urothelial tumors. Even though some unfavorable features of the reusable flexible scopes can limit the surgical procedure such as their availability, lack of sterilization or costly repairs. Disposable scopes have been developed with the intention of improving such problems. RECENT FINDINGS: To our knowledge, seven devices have been developed...

Diabetes and obesity are already recognized as potential risk factors for nephrolithiasis, especially for uric acid stones. Insulin resistance and hyperinsulinemia actively contribute to impaired ability to excrete an acid load and altered ammonium production, leading to a lower urinary pH compared to non-diabetic controls. All these electrolytic disorders play an important role in stone formation and aggregation, especially in uric acid stones. There are still missing points in scientific evidence if the increased risk in stone formation is already existing even in the prediabetic statuses (isolated impaired glucose tolerance, isolated impaired fasting glucose, and associated impaired glucose tolerance/impaired fasting glucose) as well as it is worth to consider the same level of risk...

Walter L Strohmaier
During the last few years, there has been relevant progress in both understanding and managing urolithiasis. Our knowledge of stone formation has changed; although the importance of urine biochemistry was questioned by several investigators years ago, the decisive role of cellular processes (induced by oxidative stress) and the renal papilla has only recently been generally accepted as the most important step in stone formation. For calcium oxalate urolithiasis, the formation of papillary calcifications plays a key role and is of prognostic relevance...

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...
