INTRODUCTION: Loss-of-function mutations in cytochrome P450 family 24 subfamily A member 1 (CYP24A1) gene are associated with Idiopathic Infantile Hypercalcemia (IIH) and adult kidney stone disease. The enzyme deficiency leads to an impaired vitamin D catabolism pathway, resulting in a syndrome characterized by recurrent hypercalcemia, hypercalciuria and suppressed parathyroid hormone (PTH) levels. In these patients, the genetic evaluation of CYP24A1 is an important diagnostic tool, allowing the definitive diagnosis of IIH...

Kidney stone disease is an increasingly prevalent condition with remarkable clinical heterogeneity, with regards to stone composition, age of manifestation, rate of recurrence, and impairment of kidney function. Calcium-based kidney stones account for the vast majority of cases, but their etiology is poorly understood, notably their genetic drivers. As recent studies indicate, hereditary conditions are most likely underestimated in prevalence, and new disease genes are constantly being identified. As a consequence, there is an urgent need of a more efficient documentation and collection of cases with underlying hereditary conditions, to better understand shared phenotypic presentation and common molecular mechanisms...

We present a case of pyeloduodenal fistula in an 89-year-old woman with history of nephrolithiasis and recurrent urinary tract infection (UTI) who presented to the emergency department with back pain. CT revealed a malrotated right kidney with a large renal stone and possible fistulous connection between the second portion of the duodenum and the right renal collecting system. Technetium-99m scintigraphy confirmed presence of the fistula. The patient declined intervention and was discharged from the hospital with oral antibiotic suppressive therapy...

Primary hyperoxaluria type 2 is a rare autosomal recessive disorder caused by glyoxylate reductase/hydroxypyruvate reductase deficiency and characterized by recurrent episodes of nephrolithiasis and nephrocalcinosis. Herein, we describe a case of primary hyperoxaluria type 2 in a 33-year-old man who failed to respond to conventional therapies; thus renal transplantation was performed. This case demonstrated that, although primary hyperoxaluria type 2 is rare, hyperoxaluria should be suspected and blood oxalate and stone component be examined in patients with recurrent episodes of nephrolithiasis, particularly in those who are unresponsive to conventional therapies...

OBJECTIVE: To evaluate the association of clinical factors on outcomes in SCI patients undergoing ureteroscopy. Immobility, recurrent urinary tract infection, and lower urinary tract dysfunction contribute to renal stone formation in spinal cord injury (SCI) patients. Ureteroscopy is a commonly utilized treatment modality, however, surgical complication rates and outcomes have been poorly defined. Evidence guiding safe and effective treatment of stones in this cohort remains scarce. METHODS: Records were retrospectively reviewed for SCI patients who underwent ureteroscopy for kidney stones from 1996-2014 at a single institution...

Tilahun Alelign, Beyene Petros
Kidney stone disease is a crystal concretion formed usually within the kidneys. It is an increasing urological disorder of human health, affecting about 12% of the world population. It has been associated with an increased risk of end-stage renal failure. The etiology of kidney stone is multifactorial. The most common type of kidney stone is calcium oxalate formed at Randall's plaque on the renal papillary surfaces. The mechanism of stone formation is a complex process which results from several physicochemical events including supersaturation, nucleation, growth, aggregation, and retention of urinary stone constituents within tubular cells...

Presence of renal calculi (kidney stones) in human urethra is being increasingly diagnosed over the last decade and is considered as one of the most painful urological disorders. Accurate analysis of such stones plays a vital role in the evaluation of urolithiasis patients and in turn helps the clinicians toward exact etiologies. Two highly complementary laser-based analytical techniques; Laser Induced Breakdown Spectroscopy (LIBS) and micro-Raman spectroscopy have been used to identify the chemical composition of different types of renal calculi...

RELEVANCE: Management of patients with large and staghorn stones of a solitary kidney is widely debated among urologists and has not been sufficiently investigated, which determined the relevance of this study. MATERIALS AND METHODS: The study comprised 80 patients with large (>20 mm) and staghorn stones of an anatomically or functionally solitary kidney. Of them, 58 patients underwent percutaneous nephrolithotripsy (PNL), and 22 had open surgery. The criterion of the treatment effectiveness was the complete stone clearance or small residual fragments sized less than 3 mm...

Nephrolithiasis is a common urological disease with high prevalence and recurrence rates. Characterizing gut microbiome profiles of nephrolithiasis patients may provide valuable insights and potential biomarkers for the disease. Therefore, we explored the relation between gut microbiome and nephrolithiasis using 16S ribosomal RNA (rRNA) gene sequencing. 13 patients with multiple kidney stones and 13 matched healthy controls were recruited. A decreasing trend in number of observed species in nephrolithiasis patients was detected, although statistical significance was not reached (p = 0...

OBJECTIVE: A highly sensitive and specific urine marker for the detection of recurrent urothelial cancer and for screening healthy population or people at risk for urothelial cancer has not been found yet. As urine cytology is not sensitive enough, patients with non-muscle-invasive bladder cancer need lifelong follow-up involving multiple invasive cystoscopies. Our aims of study were to examine the expression of semaphorin 3A in urothelial cancer patients and to evaluate semaphorin 3A as a potential marker for urothelial cancer...

BACKGROUND: There is a critical need for improved prognostic discrimination in patients with renal cell carcinoma (RCC) given the increasing awareness that some patients may be managed with active surveillance, while others with higher-risk disease might benefit from adjuvant therapy following surgery. OBJECTIVE: To determine whether a multigene proliferation signature predicts long-term oncologic outcomes in surgically resected RCC. DESIGN, SETTING, AND PARTICIPANTS: The cell cycle proliferation (CCP) score was determined after radical nephrectomy for localized clear cell, papillary, or chromophobe RCC in 565 patients...
