It has been proposed that epithelial dysfunction and inflammation may predispose patients to kidney stone formation. Asthma is another chronic condition related to epithelial dysfunction and inflammation. We hypothesized that pediatric patients with asthma would have an increased prevalence of nephrolithiasis. Furthermore, we investigated if asthma patients with nephrolithiasis have clinical characteristics and urine profiles that point to mechanisms of stone formation. We evaluated 865 pediatric patients who had a diagnosis of nephrolithiasis...

OBJECTIVE: Stoss treatment has also been suggested due to non-skeletal benefits of vitamin D in adults, but no sufficient data are present about the optimal dose of vitamin D replacement in children with vitamin D deficiency/insufficiency without rickets. This study aimed to compare efficiency/side effects of two different stoss therapy regimens (10.000 IU/kg and 300.000 IU vitamin-D3) administered in children with vitamin D deficiency/insufficiency without rickets. METHODS: Sixty-four children who had vitamin-D deficiency/insufficiency were studied...

BACKGROUND: Calcium nephrolithiasis is associated with an increased risk of osteoporosis and fracture. Hypercalciuria has been assumed to be pathogenic for bone loss in kidney stone formers (KSF), although this association was shown in small cross-sectional studies. We explored the association of urine calcium (UCaV) with bone mineral density (BMD) in KSF. METHODS: We retrospectively studied BMD in KSF. Excluded were subjects with hypercalcemia, chronic bowel disease, primary hyperparathyroidism, distal renal tubular acidosis or endogenous creatinine clearance <40 ml/min...

Cystinuria is an inherited disorder characterized by defective renal reabsorption of cystine and dibasic amino acids leading to nephrolithiasis. This study was conducted to analyze the genotypes and phenotypes of pediatric patients with cystinuria. Eight children from Seoul National University Hospital and Asan Medical Center presenting with cystinuria from January 2003 to June 2016 were retrospectively analyzed. Mutational studies were performed by direct sequencing. Two of the 8 were male and 6 were female...

UNOS recommends that fellowship-trained surgeons participate in 15 LDN to be considered proficient. ASTS mandates 12 LDN during abdominal transplant surgery fellowship (ATSF). We performed a retrospective intraoperative case analysis to create a risk-adjusted cumulative summation (RACUSUM) model to assess the learning curve (LC) of novice TSF (nTSF). Between January 2000 and December 2014, 30 nTSF rotated on the Organ Procurement Rotation (OPR) of our ASTS-approved ATSF. Measures of surgical performance included: 1) intraoperative time (ORT), 2) estimated blood loss (EBL), and 3) incidence of intraoperative complications (IOC)...

Inherited distal renal tubular acidosis (dRTA) is caused by impaired urinary acid excretion resulting in hyperchloremic metabolic acidosis. Although the glomerular filtration rate (GFR) is usually preserved, and hypertension and overt proteinuria are absent, it has to be considered that patients with dRTA also suffer from chronic kidney disease (CKD) with an increased risk for adverse pregnancy-related outcomes. Typical complications of dRTA include severe hypokalemia leading to cardiac arrhythmias and paralysis, nephrolithiasis and nephrocalcinosis...

In this study, we explored if urinary lithogenic risk parameters could have some application for monitoring bone health status. We recruited 20 women with postmenopausal osteopenia and a negative medical history for nephrolithiasis. Markers of lithogenic risk were evaluated on 24-h urine and fastingmorning urine. Serum levels of bone turnover markers (BTM) were measured in fasting-blood samples. We found that cross-linked telopeptide of type I collagen (CTX) was significantly correlated with 24-h calcium excretion...

Spinal cord injury patients are at increased risk of developing nephrolithiasis and may require percutaneous nephrolithotomy for treatment of large stone burdens. Our objective was to compare outcomes of PCNL in SCI patients as compared to a matched cohort of non-SCI patients. Data from the Healthcare Cost and Utilization Project State Inpatient Database for Florida and California were used to identify patients by ICD-9 codes who underwent PCNL between 2007 and 2011. SCI was identified by having a paralysis diagnosis on the chronic comorbidity indicator...

BACKGROUND: The efficacy and safety of various modes of medical treatment for primary hyperparathyroidism in pregnancy are largely unknown. CASE PRESENTATION: We report the case of a 34-year-old white woman with primary hyperparathyroidism symptomatic for nephrolithiasis. Her serum calcium was 3.15 mmol/l and parathyroid hormone was 109.0 ng/L. Neck imaging found no pathological parathyroid tissue. Cinacalcet and cholecalciferol were started. She became pregnant 17 months later...

Keratinizing desquamative squamous metaplasia (KDSM) in the renal pelvis is a rare condition with unclear malignant potential. Recent reports suggest it is likely benign and favor endoscopic treatment approaches. Medical record review was completed on two cases at our center to obtain history, physical examination, radiographic findings, and management. A literature review was completed to identify all published cases of KDSM. Both patients at our center suffered recurrent urolithiasis, hypothesized to be secondary to KDSM...

BACKGROUND: Patients with medullary sponge kidney (MSK) commonly encounter recurrent nephrolithiasis. The existing knowledge on safety of donors with MSK has not been studied. METHODS: We conducted a retrospective cohort study at a tertiary referral hospital to assess the outcomes of living kidney donors with MSK. All adults with MSK (N = 26) who underwent nephrectomy as living kidney donors between January 2000 and September 2014 were included. Non-donors with MSK (N = 78) were randomly selected by matching the year of birth and the comorbidity score with a ratio of 1:3 for comparison...

BACKGROUND: Adenine phosphoribosyltransferase deficiency is an inborn error of metabolism that can cause kidney disease from crystalline nephropathy or kidney stones. METHODS: We present three cases from a single centre with varied presentations to illustrate how increasing awareness led to better patient identification. We then undertook a cross-sectional survey of all the patients identified from the Purine Research Laboratory in the UK since 1974. RESULTS: Our index case presented with recurrent nephrolithiasis and was diagnosed on stone analysis, the second case presented with acute kidney injury and the third case was identified from a biopsy undertaken for acute on chronic kidney injury...

BACKGROUND: Ovarian torsion is a rare but serious cause of pelvic pain in females. Making the diagnosis is important because misdiagnosis can lead to an ischemic ovary and subsequent infertility. OBJECTIVE: Although all emergency physicians are aware of ovarian torsion, there are several myths regarding its epidemiology, diagnosis, and treatment. This article attempts to review some of these myths to improve emergency diagnosis and evaluation. DISCUSSION: Ovarian torsion is not an easy diagnosis to make and it is commonly missed...

While vitamin D (vitD) deficiency is thought to contribute to poor health in a variety of ways and should be corrected, there is still concern about giving vitD supplements to patients with a history of nephrolithiasis. The aim is to study the prevalence of vitD deficiency and the effect on stone risk of cholecalciferol (vitD3) supplementation in a cohort of idiopathic stone formers (ISF). We screened for vitD deficiency and urinary measures of stone risk, comparing vitD deficient (serum 25-OH vitD ≤30 nmol/L; ≤12 ng/mL) with vitD insufficient (31-75 nmol/L; 13-30 ng/mL) or vitD replete (>75 nmol/L; >30 ng/mL); we investigated the effect of giving vitD3 (20,000 IU orally, weekly for 4 months) to 37 of the vitD deficients...

Already known to ancient Egyptians, gout is one of the first diseases which have been described as a clinical entity. To date, gout is the most common form of inflammatory arthritis. Gout is defined by the deposition of monosodium urate crystals within tissues, causing episodes of acute arthritis and the development of tophi, nephrolithiasis, and urate nephropathy. Hyperuricemia, i.e. levels of serum uric acid above 6.8 mg / dL(404mol/L), is a condition necessary, yet not sufficient for gout to develop. The increasing incidence of risk factors such as hypertension, obesity, and renal failure together with an ever-growing life expectancy has led in recent decades to a significant increase in gout prevalence, which has more than doubled when compared to the 1960s...

Oxalate (Ox) is an end-product of metabolism, important for poor solubility of its calcium salt in biological fluids. Ox can therefore be found in about 70% of urinary calculi. Hyperoxaluria (HOx) defined as Ox exceeding 0.5 mmol)/day, may cause nephrolithiasis/nephrocalcinosis and may be classified as dietary (DH), enteric (EH) or primary (PH). Fractional intestinal absorption of Ox is less than 10%, but increases to over 20% at calcium intakes below 200 mg/day. DH is often related to low-calcium diets. EH is caused by non-absorbed fatty acids which bind to calcium and lower its concentration in the intestinal lumen...

Nephrolithiasis is one of the most frequent urologic diseases. The aim of this paper is to study the composition and frequency of 8854 patient kidney stones and in a subset of them their metabolic risk factors to be related to their type of calculi. Physicochemical and crystallographic methods were used to assess kidney stone composition. In a subset of 715 patients, we performed an ambulatory metabolic protocol with diagnostic purposes. From the total sample 79% of stones were made of calcium salts (oxalate and phosphate), followed by uric acid stones in 16...
