Uric acid is a product of purine metabolism and has been linked to gout and kidney calculi. Chronic kidney disease (CKD) and hypertension (HTN) are two major public health problems, and both are associated with increased risk of cardiovascular events. Emerging evidence suggests a pathogenic role of hyperuricemia in the development of HTN and CKD, in addition to progression of CKD, by inducing renal inflammation, endothelial dysfunction, and activation of the renin-angiotensin system. In addition, several epidemiological studies have linked hyperuricemia with an increased risk of HTN and CKD...

Upper urinary tract rupture in the absence of trauma is typically related to ureteric calculi causing obstructive nephropathy. Spontaneous extravasation of contrast during CT intravenous pyelography (CT IVP) is infrequently reported. Two cases, who underwent CT IVP to further investigate positive urine cytology and microscopic haematuria, respectively, are described here. In both cases, there was spontaneous extravasation of contrast seen in the postcontrast scans in the absence of ureteric calculi or hydronephrosis which is very unusual...

To assess the outcomes of percutaneous nephrolithotomy (PCNL) in bilateral staghorn calculi in pediatric patients, we have performed a retrospective analysis. Staghorn calculus is defined as stone that fills a greater part of the pelvic-caliceal system. Still, in developing countries, patients may present with staghorn calculus. PCNL is the preferred treatment modality for staghorn calculus both in adult and children. Our study included fifty-one pediatric patients (<15 years) of bilateral staghorn calculi from 2004 to 2015...

INTRODUCTION: Paraplegic patients are at greater risk of developing complications following ureteroscopic lithotripsy because of urine infection associated with neuropathic bladder, difficulties in access due to altered anatomy of urinary bladder and urethra, spinal curvature, spasticity, and contractures. We report the occurrence of large subcapsular hematoma following ureteroscopy and discuss lessons we learn from this case. CASE REPORT: A 48-year-old male patient with spina bifida underwent ureteroscopy with laser lithotripsy and ureteric stenting for left ureteric stone and staghorn calculus with hydronephrosis; laser lithotripsy was repeated after 3 months; both procedures were performed by a senior urologist and did not result in any complications...
