Primary hyperoxaluria (PH) patients overproduce oxalate because of rare genetic errors in glyoxylate metabolism. Recurrent urolithiasis and/or progressive nephrocalcinosis are PH hallmarks and can lead to kidney damage, systemic oxalosis and death. Based on previous studies, we hypothesised that treatment with the oxalate-metabolizing bacterium Oxalobacter formigenes would mediate active elimination of oxalate from the plasma to the intestine of PH patients, thereby reducing urinary oxalate excretion (Uox)...

Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive error of purine metabolism resulting in the generation of 2,8-dihydroxyadenine (DHA), a highly insoluble metabolite of adenine, which can cause radiolucent urolithiasis. This is the second case of DHA stone being reported in India and the first case in India to document the mutation of the APRT gene on blood DNA analysis.

REVIEW
Diana Cardona-Grau, George Chiang
In the United States, there are an estimated 25,000 children ages 0 to 19 years and about 166,000 of all ages currently affected by spina bifida. Management is multimodal and can be complex. Management techniques vary throughout a child's lifetime, but the goals remain the same: prevention of urinary tract infections and establishing acceptable continence. Continence is addressed as the child reaches school age. Additional considerations such as development of urolithiasis and the associated burden are highlighted in adolescence and into adulthood...

BACKGROUND: There are currently three distinct autosomal recessive inherited types of primary hyperoxaluria (PH: PHI, PHII, and PHIII), all characterized by the endogenous overproduction of oxalate. The PH type is difficult to differentiate by clinical features alone. In addition to universal general characteristics to all hyperoxaluria subtypes, specific urinary metabolites can be detected: glycolate in PHI, L-glyceric acid in PHII, and hydroxy-oxo-glutarate (HOG) in PHIII. PHIII is considered to be the most benign form and is characterized by severe recurrent urolithiasis in early life, followed by clinical remission in many, but not all patients...

The cross-sectional study described the epidemiology of 8560 canine urolith submissions from Thailand to the Minnesota Urolith Center between January 2009 and December 2015. The frequency of urolith types, the relationships between urolith type and breed, sex, and neutered status, and change of annual submission proportion over the study period were analyzed. Struvite was the most common canine urolith (44%), and was commonly found in intact females with a mean age of 6.3±3.1years. Calcium oxalate was the second most common (27%), more frequently found in intact males with a mean age of 8...

BACKGROUND: Computed tomography of the kidneys, ureters and bladder is the recommended imaging modality for suspected urolithiasis. Early scanning is advised in guidelines, but there is limited published evidence to support this recommendation. PATIENTS AND METHODS: In a retrospective study, we reviewed patients managed according to a local guideline. Patients without high-risk features were either imaged during their initial visit (if in the daytime) or discharged for outpatient scans...

A shock wave, which carries energy and can propagate through a medium, is a type of continuous transmitted sonic wave with a frequency of 16 Hz-20 MHz. It is accompanied by processes involving rapid energy transformations. The energy associated with shock waves has been harnessed and used for various applications in medical science. High-energy extracorporeal shock wave therapy is the most successful application of shock waves, and has been used to disintegrate urolithiasis for 30 years. At lower energy levels, however, shock waves have enhanced expression of vascular endothelial growth factor, endothelial nitric oxide synthase, proliferating cell nuclear antigen, chemoattractant factors and recruitment of progenitor cells; shock waves have also improved tissue regeneration...

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...

Quercus gilva Bume (QGB, family Fagaceae) is a tall evergreen oak species tree that grows in warm temperate regions in Korea, Japan, China and Taiwan. Quercus plants have long been the basis of traditional medicines. Their clinical benefits according to traditional medicine include relief of urolithiasis, tremors and inflammation. In the present study, the anti-urolithiasis activity including anti-inflammatory and anti-oxidative activities, of some phenolic compounds isolated from QGB were described. Seven compounds were isolated and identified as picraquassioside D (1), quercussioside (2), (+)-lyoniresinol-9'α-O-β-d-xylopyranoside (3), (+)-catechin (4), (-)-epicatechin (5), procyanidin B-3 (6), and procyanidin B-4 (7)...
