Upper urinary tract calculi with infection is a quite difficult acute urologic emergency. And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation. Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk. But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying...

BACKGROUND: With a high rate of recurrence, urolithiasis is a chronic disease that impacts quality of life. The Patient Reported Outcomes Measurement Information System is an NIH validated questionnaire to assess patient quality of life. We evaluated the impact of urolithiasis on quality of life using the NIH-sponsored PROMIS-43 questionnaire. MATERIALS AND METHODS: Patients reporting to the kidney stone clinic were interviewed to collect information on stone history and demographic information and were asked to complete the PROMIS-43 questionnaire...

REVIEW
Martino Marangella
Citrate is a tricarboxylic acid and an intermediate metabolite of Krebs cycle. It contributes to oxidative metabolism of both kidney and liver. Alkaline sodium or potassium salts have the potential to increase alkaline reserve. In the kidney citrate is completely filtered at the glomerulus, undergoing to 10-40% tubular resorption. Renal insufficiency, even early, metabolic acidosis, potassium depletion induce hypocitraturia. Its importance in nephrolithiasis stems from its ability to form soluble complexes with calcium and to interfere with crystal formation, thus exerting a dual inhibition, thermodynamic and kinetic...

CONTEXT: Urolithiasis has a high prevalence and recurrence rate. Prevention is key to patient management, but risk stratification is challenging. In particular, genetic predisposition for urinary stones is not fully understood. OBJECTIVE: To review current evidence of potential causative genes for idiopathic urolithiasis and map their relationships to one another. This evidence is essential for future establishment of molecular targeted therapy. EVIDENCE ACQUISITION: A systematic literature review from 2007 to 2017 was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines...

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)...

The lack of Oxalobacter formigenes colonization of the human gut has been correlated with the formation of calcium oxalate kidney stones and also with the number of recurrent kidney stone episodes. Here, we present the genome sequence of HC-1, a human strain isolated from an individual residing in Iowa, USA.

The association between nephrolithiasis and acromegaly has been previously described. Although the mechanism has been established, the urological literature sparsely discusses clinically suspecting that patients with recurrent nephrolithiasis could have acromegaly and subsequently referring them for accurate diagnosis and treatment. We present a case of occult acromegaly secondary to a pituitary tumor discovered 20 years after the patient's first stone episode.

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...

Context: Options for chronic treatment of hypoparathyroidism include calcitriol, recombinant human parathyroid hormone, and high-dose vitamin D (D2). D2 is used in a minority of patients because of fear of prolonged hypercalcemia and renal toxicity. There is a paucity of recent data about D2 use in hypoparathyroidism. Objective: Compare renal function, hypercalcemia, and hypocalcemia in patients with hypoparathyroidism treated chronically with either D2 (D2 group) or calcitriol...

Bilateral ureteral duplication is a very rare anomaly, a result of two separate ureteric buds arising from a mesonephric duct. Most of the patients are asymptomatic and diagnosed incidentally. Recurrent urinary tract infections, incontinence, haematuria, stone formation and flank pain are common clinical symptoms. Intravenous urography, computed tomography urography, and magnetic resonance imaging are the diagnostic modalities. In this report, a case of bilateral ureteral duplication with stone formation in the lower pole of the right kidney is presented along with its management...

OBJECTIVES: Living-related kidney donation is the main source of renal grafts in Jordan, since kidneys from deceased donors are scarce. Although the Jordanian community accepts the idea of kidney donation to family members, not all potential donors manage to complete the required psychologic and medical evaluations. We review the causes of kidney-donation cancellation and suggest options to increase the number of available organs. MATERIALS AND METHODS: We performed a retrospective chart review of all potential living-related kidney donors at King Hussein Medical Center between January 2008 and June 2016...

The present investigation is focused on exploring the anti-urolithiatic potential of aqueous leaf extract of Tragia involucrata (TIA) and its silver nanoparticles (AgNPs) and to quantify the total phenol, flavonoid, terpenoid and sterol contents present in TIA. Quantification results suggested TIA to be a rich source of phenol, flavonoid and terpenoid and less of sterol content. The AgNPs were synthesized by a simple green method using aqueous extract of T. involucrata. The formation of AgNPs was confirmed through UV spectroscopy, particle size analysis, zeta potential, X-ray diffraction and transmission electron microscopy...
