INTRODUCTION: Interventional radiologist may be hesitant to obtain upper pole access for percutaneous nephrolithotomy (PCNL) due to a higher complication rate. Renal access gained by urologists may achieve higher stone-free rates with similar complication rates. We evaluate our institution's contemporary results of percutaneous renal access in the upper pole for nephrolithotomy by urologists, which we believe both safe and efficacious. MATERIALS AND METHODS: This retrospective chart review included all PCNL's performed by fellowship-trained endourologists from 2003 to 2014 at a single institution...

Kidney Stone Disease (KSD) is a complex urologic disorder with strong genetic constituent. Earlier association studies have indicated that the genetic polymorphisms are the potential cause of stone materialization; however unfortunately, the actual genetic signature is still unknown. Therefore, present study was aimed to investigate the potential contribution of two important polymorphisms of calcitonin receptor gene (CALCR): (i) rs1801197 (Leu447Pro) and (ii) rs1042138 (3'UTR+18C>T) in renal stone formation...

BACKGROUND: Transurethral intracorporeal lithotripsy is the modality of choice for the endoscopic disintegration of large, long-standing, radiolucent or high-density stones. Despite several advantages and proven benefits of contact ureterolithotripsy/ureterolithoextraction (CULT), the application of irrigation carries significant risks of untoward perioperative events including retrograde stone migration and postoperative pyelonephritis. METHODS: We describe a new technique - endoscopic intracorporeal lithotripsy in the gas (СО2) medium...

Circadian periodicity of plasma lipid peroxides and serum ascorbic acid and uric acid levels were studied in one hundred renal stone formers (55 women and 45 men; age 20-60 years) and 50 clinically healthy volunteers (21 women and 29 men; age 21-45 years) with diurnal activity from 06:00 to 22:00 and nocturnal rest. A marked circadian variation was demonstrated by population-mean-cosinor for all studied variables in stone formers and healthy subjects. By comparison to the healthy controls, parameter tests indicate that the stone formers had a higher MESOR (±SE) of MDA (2...

BACKGROUND: Urolithiasis is a global problem whose incidence is reported to be on the rise across the world. Previously, urolithiasis was reported as being rare among the indigenous African population but recent data suggest otherwise. This study reviewed the demographic and clinical characteristics of patients with urolithiasis seen at the Aga Khan University hospital Nairobi (AKUHN) as well as the chemical composition of the stones and the modalities of therapy used. METHODS: This was a retrospective study which utilized patients' clinical and laboratory records from 2013 to 2014...

Diabetic kidney disease (DKD) is a major complication of diabetes, and serves as an important cause of end-stage renal disease (ESRD). The role of chronic inflammation in DKD is becoming widely accepted. Pancreatic stone protein/regenerating protein (PSP/reg) is a secretory protein, which is elevated in blood during infected conditions and organ failure. The aim of this study was to investigate the relationship between serum PSP/reg and DKD in patients with type 2 diabetes (T2DM). A total of 120 subjects which includes newly diagnosed T2DM patients, diabetes patients without DKD, DKD patients, as well as healthy controls were enrolled in this study...

In the context of ante-natally diagnosed hydronephrosis, the vast majority of children with a dilated renal pelvis do not need any surgical treatment, as the dilatation resolves spontaneously with time. Slow drainage demonstrated at Tc-99m-mercaptoacetyltriglycine (MAG3) renography does not necessarily mean obstruction. Obstruction is defined as resistance to urinary outflow with urinary stasis at the level of the pelvic-ureteric junction (PUJ) which, if left untreated, will damage the kidney. Unfortunately this definition is retrospective and not clinically helpful...

BACKGROUND: Emergency departments (EDs) are gateways for patients presenting after minor surgical procedures, particularly shockwave lithotripsy. Complications include renal and extrarenal tissue injuries, with the latter having potentially serious consequences if not detected early. CASE REPORT: We describe a 70-year-old male presenting to the ED for syncope. The patient underwent shockwave lithotripsy (SWL) for left kidney stones 1 day prior. Upon initial evaluation, the patient had normal vital signs and a normal physical examination, without complaints of abdominal pain...

Metabolic syndrome (MS) individuals have a higher risk of developing chronic kidney disease through unclear pathogenic mechanisms. MS has been also related with higher nephrolithiasis prevalence. To establish the influence of MS on renal function, we designed a murine model of combined metabolic syndrome and hyperoxaluria. Four groups of male Sprague-Dawley rats were established: (1) control group (n = 10) fed with standard chow; (2) stone former group (SF) (n = 10) fed with standard chow plus 0.75% ethylene glycol administered in the drinking water; (3) metabolic syndrome group (MS) (n = 10), fed with 60% fructose diet; (4) metabolic syndrome + stone former group (MS + SF) (n = 10), 60% fructose diet and 0...
