NSAIDs provide optimal analgesia in renal colic due to the reduction in glomerular filtration and renal pelvic pressure, ureteric peristalsis and ureteric oedema. Prevention of glomerular afferent arteriolar vasodilatation renders these patients at risk of renal impairment. NSAIDs have the additional benefit of reducing the number of new colic episodes and preventing subsequent readmission to h...

BACKGROUND AND PURPOSE Most series on ureteroscopy for urolithiasis use postoperative plain radiography of the kidneys, ureters, and bladder (KUB) or intravenous urography (IVU) to determine outcomes. These imaging modalities, however, are not very sensitive and may overestimate stone-free rates (SFRs). The aim of our study was to assess SFRs after ureteroscopy for urolithiasis using CT follow-...

In this study, we aim to evaluate and compare the effectiveness of flexible ureterorenoscopy (f-URS) for solitary and multiple renal stones with < 300 mm2 stone burden. Patients' charts who treated with f-URS for kidney stone between January 2010 and June 2015 were reviewed, retrospectively. Patients with solitary kidney stones (n:111) were enrolled in group 1. We selected 111 patients with mul...

cartilage hair hypoplasia (chh), is a rare cause of metaphyseal chondrodysplasia and short stature. other features included hair abnormality, immunodeficiency, anemia, gastrointestinal disorders (hirschsprung disease, celiac, …) and increased risk of cancer. the disease is an autosomal recessive disorder and previously has not been reported in iran. we report a 9-year-old boy diagnosed as carti...

BACKGROUND Extracorporeal shockwave lithotripsy (ESWL) is the management of choice for renal stones 20 mm or smaller, with a stone clearance rate of up to 89%. The purpose of the present is to investigate the efficacy of a commercialised ESWL service, being performed as an outsourced treatment using a mobile lithotripsy system on an outpatient basis. Furthermore, the study aims to evaluate the ...

PURPOSE The aim of this study was to evaluate possible predictive variables for the outcome of shock wave lithotripsy (SWL) of renal stones in a single center. MATERIALS AND METHODS Between March 2008 and March 2010, a retrospective review was performed of 115 patients who underwent SWL for solitary renal stones. The patients' characteristics and stone size, location, skin-to-stone distance (...

background: the aim of this study was to describe the one-decade experience in percutaneous nephrolithotomy surgery in children with kidney stones in tehran, iran. methods: all patients (less than 18 years old) undergoing percutaneous nephrolithotomy at our referral medical center, were reviewed in this cross-sectional study. all the demographics, surgical data and post-operative information we...

Renal stone disease is characterized by the differences depending on the age, gender, and the geographic location of the patients. Seventy-five percent of the renal stone components is the calcium (Ca). The most common type of the stones is the Ca oxalate stones, while Ca phosphate, uric acid, struvite, and sistine stones are more rarely reported. Other than these types, triamterene, adenosine,...

Renal stone formation (nephrolithiasis) is a worldwide problem causing substantial morbidity and economic burden. The heritability of stone formation has long been recognized, and with the advent of the genomic era, we have the potential to define the underlying genetic defects. Renal stone formation is multifactorial, with environmental factors interacting with underlying genetic factors. Isol...
