INTRODUCTION:  Immediate ureteroscopic treatment for patients presenting to the emergency room with symptomatic ureterolithiasis is more commonly being utilized. Recent reports demonstrate good efficacy for emergency URS, however preoperative predictors of treatment success have not been described. Here, we report our multi-center experience with emergency URS and identify predictors of successful treatment. We also describe the Emergency Ureteral Stone Treatment (EUST) Score, which integrates these predictors and stratifies patients into those that are likely and unlikely to have successful treatment...

AIM: To successfully treat and prevent urolithiasis, the composition and structure of uroliths should be examined using modern analytical techniques. For a long time, studies of the biomineral formation in the human body have been conducted exclusively in the field of medicine. The main attention has been paid to the diagnosis and treatment of diseases leading to the occurrence of pathogenic formations. At the same time, it is quite obvious that it is important to have a clear idea about the causes of pathogenic formations, the mechanisms for their further formation, composition and structure...

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...

Primary hyperoxaluria type 1 is an autosomal recessive hereditary glyoxylate metabolism disorder characterized by excessive production of oxalate, caused by the deficiency of liver specific peroxisomal enzyme: alanineglyoxylate aminotransferase. For patients with end-stage renal disease, combined liver and kidney transplantation was needed. This report describes one patient, with a diagnosis of end-stage renal disease and primary hyperoxaluria 1 confirmed by PCR and direct sequencing with genomic DNA, received the simultaneous combined liver and kidney transplantation after seven months' waiting...

INTRODUCTION: Health related quality-of-life is increasingly important in quality improvement efforts for medical conditions but has proved challenging to measure for urolithiasis given the distinct chronic and acute phases of this disease. We evaluated the utility of using the Patient-Reported Outcomes Measurement System (PROMIS(®)) to assess patient experience through stages of the acute stone episode. MATERIALS AND METHODS: PROMIS(®) pain measures (intensity and interference) were obtained from patients at a subspecialty kidney stone clinic...

INTRODUCTION: Urinary tract infections (UTI) caused by Escherichia coli (E. coli) are common in patients with idiopathic hypercalciuria. As both UTI and hypercalciuria (prelithiasis) have a genetic basis, we wanted to know whether the family history of urolithiasis is more common in children with UTIs caused by E. coli. Secondarily, we wondered if the renal scars are more common in children with prelithiasis. MATERIAL AND METHODS: Ambispective study with collected data from 104 patients (40 male, 64 female) followed after having been diagnosed of UTI by E...

Our previous study has shown that lime powder (LP) had an inhibitory effect against calcium oxalate stone formation. However, the precise mechanisms underlying such beneficial effect remained unclear. Our present study thus aimed to address the effect of LP on excretory level and compositions of urinary proteins using a proteomics approach. From a total of 80 calcium oxalate stone formers recruited into our 2-year randomized clinical trial of LP effect, 10 patients with comparable age and clinical parameters were selected for this proteomic study...

BACKGROUND: Primary hyperoxaluria type 2 is a rare monogenic disorder inherited in an autosomal recessive pattern. It results from the absence of the enzyme glyoxylate reductase/hydroxypyruvate reductase (GRHPR). As a consequence of deficient enzyme activity, excessive amounts of oxalate and L-glycerate are excreted in the urine, and are a source for the formation of calcium oxalate stones that result in recurrent nephrolithiasis and less frequently nephrocalcinosis. CASE PRESENTATION: We report a case of a 10-month-old patient diagnosed with urolithiasis...

Desmosium styracifolium (D. styracifolium), which is considered as a Chinese herbal medicine, has been reported to treat the kidney stone diseases. However, the potential phytochemically active components and the underlying mechanisms associated with its efficacy in targeting urolithiasis remain to be elucidated. This study aims to investigate the anti-urolithiatic effect of total flavonoids of D. styracifolium (TFDS) on calcium oxalate (CaOx) renal stones in Sprague-Dawley rats. Animal models of CaOx urolithiasis were established in male Sprague-Dawley rats by adding 5% w/w hydroxy-L-proline (HLP) in regular rat chow...
